Why Are Jeans so Soft? Reasons for Jeans Fabric

What are the specifications of denim? There seem to be many classifications, right? Jeans, as the name suggests, are made of denim fabric. If someone asks what fabric jeans are made of, I believe many people will laugh. The fabric used in jeans is a thick yarn dyed warp twill cotton, in which the warp color is darker, indigo, and the weft color is lighter. Generally, it is light gray or white yarn after scouring. The Chinese view of this kind of cloth is like linen, so it is called labor cloth.In the past, when jeans were just launched, Chinese people didn't buy it. They thought that this kind of heavy cloth clothing was only suitable for working. Unexpectedly, in a few years, this kind of jeans clothing was highly respected by young people. Now even the old man won't ask what material jeans are.China's cowboy products started relatively late, but they started relatively high because they learned from foreign production levels. Chinese denim products have production equipment such as rotor spinning, automatic winding, shuttleless loom and so on. Therefore, the quality of the produced denim fabric is not inferior to that of foreign brands. What is the fabric of jeans? Jeans are the fabric jointly produced by the above equipment. At first, denim fabrics generally faded. Some of today's jeans have added special processes to prevent them from fading.What material are jeans? Foreign countries are constantly improving denim fabrics, and China is constantly pushing new denim fabrics. This kind of fabric has become an indispensable kind of fabric in the market, and this kind of fabric will continue to contribute to the beautiful human beings. People who like denim fabrics can have a look at the production technology and common sense of denim fabrics, which is the best lesson for buying high-quality jeans.

Key points: the demand for eco-friendly denim fabrics is leading this category whose sales have been declining for many years to make a comeback. traditional cowboy brands are implementing more environmentally friendly production processes to cope with the rise of emerging enterprises, which have integrated sustainability into their DNA. truly sustainable development needs to go beyond the production stage and focus on the life cycle of denim.After years of declining sales, denim fabrics are making a comeback. According to Euromonitor, sales of jeans in the United States have fallen by 11% in the past five years. However, driven by sports and leisure clothing, the sales of overall clothing increased by 10%. Globally, cowboy sales fell 2.3%. Euromonitor predicts that by 2023, the revenue of American jeans will increase by 5% to US $17.5 billion, while the global revenue will increase by 11% to US $111.6 billion.LYST, a global fashion search platform, said that the search volume of jeans was 13 times per second, ranking third in the global search volume, second only to sneakers and dresses. Consumer inquiries reflect changes in demand. On the LYST platform, the search volume of "sustainable" jeans has increased rapidly in the past year, with an increase of 193%, surpassing the search terms such as "Mom jeans" and "skinny denim". This transformation takes place in a new era of sustainable development, and this transformation is touching every corner of the industry. "People are more aware than ever of the impact of fashion and excessive shopping on the environment," said Chana Baram, retail analyst at MintelThis has prompted jeans manufacturers rooted in traditional country images and brands to change their practices. For example, Wrangler is abandoning the marketing concept of "original denim jeans" and promoting its new foam dyeing and anhydrous production process. The process claims that compared with the traditional method, its energy consumption is reduced by 60% and the chemicals used are reduced by 90%."Today's situation is different. In the past, enterprises need to deal with global issues such as climate change. In the case of continuous innovation in other industries, it would be irresponsible if the cowboy industry stagnates," said roian Atwood, director of sustainable business of WranglerEnvironmental cost of denim fabricDenim is everywhere, but it is very harmful to the ecological environment. According to Greenpeace, 1.7 million tons of chemicals are needed to produce 2 billion pairs of jeans a year, and the water consumption of each pair of jeans is as high as 7000 litres.The measures to solve this problem are led by emerging enterprises directly facing consumers such as everlane and transformation. They believe that sustainability is the key to their DNA and a big difference from traditional brands. But traditional enterprises are also changing.Levi's, for example, focuses on significantly reducing water consumption in the production of denim fabrics. In terms of retail value, the company is the best-selling jeans brand in the world. The company's goal is that by 2020, 80% of its products will be produced by technology with water saving up to 96%. At present, 67% of its products will be produced by this method.In order to greatly improve efficiency, Levi has set their own water use goals for key suppliers according to the local water shortage. According to the data of the World Resources Institute, India and Pakistan are the locations of several denim fabric factories, and they are also one of the countries with high risk of water shortage crisis. "This will save a lot of water in the short term for areas that need more water," said Michael Kobori, Levi's global vice president for sustainable development. The company plans to reduce the cumulative water consumption of "water deficient areas" by 50% by 2025.It is not just traditional denim companies that are changing their production methods.Fast Retailing, which owns brands such as UNIQLO, J brand, Helmut Lang and comptoir des cotonniers, produced about 18 million jeans in autumn and winter 2019, but the company said that compared with the traditional method, the water saving this time was reduced by at least 90%. The company established the jeans Innovation Center (JIC) in Los Angeles to produce jeans for all its major brands. The Japanese group plans to produce 40 million jeans by 2020.Masaaki Matsubara, chief operating officer of JIC under Fast Retailing, said: "as the world's third largest clothing retailer, our scale is accompanied by responsibility. We don't want to manufacture or sell products that are not conducive to the environment. Our goal is to redefine the sustainability of clothing and let customers make sustainable purchases without worry."The efforts of these companies have also been recognized. In 2018, Levi's contribution to sustainable development ranked 37th on Fortune magazine's "change the world" list, which recognizes companies that have a positive impact on society. In Barron #s's annual ranking of more sustainable U.S. companies, PVH group (clothing group) jumped to No. 12, after ranking No. 37.Return on investment from sustainable developmentResearch shows that sustainable supply chain can improve profits: a report released by global fashion agenda and Boston Consulting Group in 2018 shows that the potential savings and efficiency obtained through sustainable operation can increase the profit margin of enterprises by 1-2 percentage points by 2030.Tommy Hilfiger of PVH group launched a permanent 100% sustainable denim series in 2019. Tommy Hilfiger believes that environmental initiatives are an investment, not a cost. Daniel grieder, CEO of Tommy Hilfiger global and PVH Europe, said that the sales of these styles of clothing in the past two quarters were "above average", and there were still great opportunities to develop and occupy market share. Although jeans account for 10% of Tommy Hilfiger's global business, the executive hopes to increase this proportion to at least 30% in the next few years.According to Atwood, Wrangler's rooted series, including sustainable and traceable products, is one of the more successful series of the brand and will become a popular online series in 2019.Preparing for circular economyThe real sustainability is not limited to a certain stage of garment production, but also includes reducing the amount of water and chemicals in the production process. The whole production cycle needs to be considered.Cowboy industry executives say there is no technology that fully supports recycling. "For cowboy brands, 100% circulation is a great goal, but there is still a lot of work to do to achieve this goal. This is not achievable by the infrastructure or technology we have today," Atwood said.Some companies have taken some early measures. Levi#s encourages resale and provides repair services through its authorized Vintage collection. "We are moving towards a more circular economy," Kobori said. Such services also provide brands with the opportunity to double profits from the same product.Brands that invest in the production process of environmentally friendly denim fabrics can get free information, which is also conducive to the formalization of industry standards. In July 2019, Ellen MacArthur Foundation, a non-profit organization focusing on circular economy and sustainable practice, issued a series of guidelines to strive to solve the waste problem in the cowboy industry by setting minimum requirements for materials and durability. The sustainability of open source can also promote group cooperation.Atwood said: "it is irresponsible for any brand to let important sustainable technologies enter the market and hold for themselves only. We encourage other brands to take advantage of our bubble dye technology." he pointed out that shortly after its launch, Gap discussed the use of foam dye technology in its brands (including Old Navy and Banana Republic). "We need to work together to change the historical footprint of such serious damage to the environment," Atwood said

Many people like to wear jeans, but do you know how to choose jeans?1. Look at the cloth. First, the quality of jeans with thick fabric is better. Second, if it is all cotton fabric, the longer the cotton wool, the better the cotton quality.2. It depends on the workmanship. Workmanship is also a key condition to measure the quality of jeans, which directly affects the experience and quality of jeans. First, check whether the sewing threads of jeans are dense and neat (those with many ends and broken threads are of poor quality). Secondly, check whether the trouser leg and waist seams are double lines and whether there is thread leakage.3. Look at the cloth inside the trouser pocket. This is the least concerned place to choose jeans, but it is also the focus of checking the brand details and quality. If the cloth in the trouser pocket is made of inferior leftovers (pilling, etc.), the quality will not be much better.4. Look at the version. Lay the jeans flat on the table to see if the left and right sides of the jeans are symmetrical.5. Look at the color. Look at the color of jeans to see if they are symmetrical, flawed, dotted and color difference. When buying jeans, try to buy pants with bright colors and soft feel. At the same time, you can tear them gently by hand at the hem. If there are slight cracks, you'd better not buy them.Jeans Maintenance Tips:Maintenance method 1: remember to soak new jeans with (white vinegar water)The new jeans have to be maintained. Before launching for the first time, prepare a basin of warm water, add a little white vinegar or salt, and then soak the newly bought jeans for about half an hour. This will help jeans better maintain the primary color and reduce the fading phenomenon!Maintenance method 2: remember to wash less jeansMany people's jeans often throw sweat stains into the washing machine. As a result, after cleaning several times, the jeans are more and more ugly, and the previous version no longer exists. Levis maintenance experts said that the maintenance secret of cleaning jeans as little as possible, and the maintenance skill he adopted is (when there are a small amount of stains, hang the jeans to be cleaned on the hook, rinse them gently with the water sprayed from the nozzle, and then scrub the stained parts with a sponge. Then he will come for a big cleaning every 6 months. The maintenance method of the big cleaning is: first fill the bathtub with warm water, add two spoonfuls of detergent in the water, and then add a little white vinegar to soak the jeans in the bath In the cylinder for a period of time).Maintenance method 3: jeans are best washed by hand, not by machineTo be honest, the biggest killer of cotton jeans is the washing machine. Often, jeans will shrink and fade seriously because they will destroy the fiber of denim cloth after machine washing, so pay special attention to maintenance.

How to distinguish the washing and maintenance of general jeans and primary jeans? When buying primary color jeans, you will certainly hear the words "Unwash" and "onewash", which are unwashed water and once washed water. Unwash is: jeans without factory washing, polishing and other treatment processes. The difference of onewash is that it has undergone pre shrinkage and desizing process before leaving the factory, so as to meet those jeans who love the softness of the upper body and want to wear their own texture beauty. Today, let's talk about some basic methods of washing and maintenance.Washing and maintenance of general jeans:1 Basic washing method(1) Before dark jeans are launched, soak them in white vinegar water (white vinegar: water, 1:20) or salt water for about 20-30 minutes to maintain the original color.(2) Wash dark and light colors separately; Mixing together will cause colors to dye each other.(3) Do not use bleach. Wash with detergent without enzyme and with blue particles. Because the detergent with enzyme has bleaching effect, it has an impact on the color of jeans.(4) Prevent direct sunlight exposure: direct sunlight exposure will cause serious oxidation and discoloration.(5) Exposure to the sun in a ventilated place: lack of ventilation will make the pants not easy to dry and will produce peculiar smell.(6) Do not wash or sun as much as possible.(7) If your jeans are made of special fabric, you can also refer to the instructions on the washing label and wash them according to the instructions listed above.2 Basic maintenance method(1) Dark cotton jeans can be worn about 3-5 times or washed once a week.(2) Light color: white, khaki, camel and other light colors depend on the dirt situation.Washing and maintenance of primary color jeans:1 Basic washing method(1) Primary color jeans can be worn when they are not dry after washing, which can produce texture faster.(2) A little white vinegar and salt are prepared in the water and dissolved in warm water. This is color fixation. The temperature of water varies from person to person. If you need to shrink more, the temperature will be higher. Even if you cook with boiling water, it will not be bad. Violent desizing will shrink very badly. If the trousers length or waist circumference is suitable at all, use cold water. It should be measured after soaking for half an hour to prevent too much shrinkage.(3) If you sweat a lot in summer, you can hang your jeans in a ventilated place, spray some water and let it dry in the wind, so that the sweat smell on your jeans won't disappear; If the jeans are stuck with some unclean things, you can spray clean water on the dirty place, then gently pick up the dirty things, hang them in a well ventilated place and dry them naturally! Reduce the amount of washing powder as much as possible, and even wash with clean water.2 Basic maintenance method(1) The cleaning time of jeans is 6-12 months.(2) Wear more and wash less. You don't need to wash in the water if you can stand the peculiar smell.(3) When wearing on the body, touch the surface of the pants with your hands. Due to the oxidation and fading of the jeans and the local area touched by the body, there is a slight role of oil esters.(4) Ordinary friends wear jeans for a week or put them into the washing machine when they are a little sweaty (dirty). In fact, it is fatal damage to the jeans. If you do this for a long time, it will make your jeans out of shape, and there will be no comfortable and beautiful leg shape. If you insist on not washing jeans, they will fit your body more and more.

What is the fabric of jeans? Let's wear jeans. They are good-looking and durable. They have been popular all over the country since they came from abroad, but do you know what the fabric of jeans is? We can't just wear jeans when we wear jeans. Today, Xiaobian will take you to know the fabric of jeans. I hope it can help you clean and maintain when you wear jeans and supplement knowledge.What are jeansJeans, also known as "strong tweed pants", is a kind of tight slacks suitable for men and women. Its structure is that the front pants have no pleats, and the back pants have no province. There are lapels and zippers in the door. An inclined pocket is installed on both sides of the front, and two straight patch pockets are installed at the back. Then the seams of the pocket opening are nailed with metal rivets and decorated with open lines. The above is the standard configuration of jeans.Jeans are widely loved by people, not only because of its unique shape, but also because jeans are wear-resistant, some fabrics are soft, fashionable and comfortable on the body, which is loved by young people.Jeans is a very special kind of clothing. Its most distinctive feature from other cloth clothing is that it has a long service life, and the value of a pair of jeans will increase with the increase of normal use and wearing time. How about it? Is it as magical as an antique. Because of the special production technology and fabric selection of jeans, jeans will become more beautiful as long as they are properly maintained and worn. The older they are, the more delicious they are. This magical feature makes jeans fans crazy.However, it is difficult to achieve the effect that the more you wash, the more delicious it is. First, jeans with good and bad fabrics not only have a very short service life, but also are uncomfortable to wear, and are easy to deform and fade. The more you wash, the more delicious it is.What are the jeans fabricsJeans are generally made of denim, ox tendon denim, which is biased towards indigo water grinding fabric. They are also made of suede, corduroy, velveteen and other fabrics. They are collectively referred to as jeans "jeans".In the beginning, the jeans were made of 100% cotton materials, and even the stitches were made of cotton thread. The dyes were synthetic indigo, copper rivets, iron zippers and buttons, plus designer signs made of cloth, leather and plastic.In recent years, the most popular market trend of jeans is to use environmentally friendly colored cotton as raw materials. The good thing about this material is that there will be no harmful by-products, and the products will not fade due to washing.

What kind of jeans do you think is good? I'd like to recommend weft stretch denim and special color denim to you. So, what kind of jeans are the best sellers this year? What type of jeans do consumers like? Let's study it?[what kind of jeans fabric is good]Weft elastic denim: with the adoption of spandex elastic wire, the variety of denim has developed to a new field, which can make the denim clothing close to the body and comfortable, coupled with bamboo knots or different colors, so that the denim products can better adapt to the fashionable and personalized consumer demand, so it has great development potential. At present, elastic denim is mostly weft elastic, and the elastic elongation is generally 20% 40%. The elastic elongation depends on the fabric organization design. The smaller the warp and weft organization tightness on the loom, the greater the elasticity. On the contrary, under the condition of fixed warp organization tightness, the greater the weft elastic yarn tightness, the smaller the elasticity and the weft tightness to a certain extent, There may even be a loss of elasticity.Special color denim: the clothing made of super indigo dyed or ultra deep indigo dyed denim can obtain the special effect of rich and bright color after grinding and processing, which is widely welcomed by consumers. "Super indigo" dyed denim has two characteristics: the dyeing depth is very deep and the color fastness to grinding is very good. The former refers to the amount of indigo dye dyed on the yarn per unit weight (generally expressed as% of the dry weight of the yarn, referred to as the dyeing depth%). For example, the indigo dyeing depth of conventional denim warp yarn is 1% 3%, while the "super indigo" dyeing depth needs to reach more than 4%, which can be called super indigo or extra deep indigo.[best selling jeans]July and August is the hottest season of the year. Among Zhixing's many denim products, denim fabrics made of Tencel, flax cotton and other materials are widely favored by customers because of their comfortable and breathable effect. At the same time, a new denim fabric with heatstroke prevention function and integrated into cold silk fiber has also been recognized by many customers.In recent years, affected by the strong rise of denim printing elements in the world, enterprises in the industry have strengthened the R & D of printed denim fabrics. As the leader of these enterprises, with years of experience and sensitive fashion sense, Zhixing has selectively formulated invisible printing and color printing jeans as the main R & D direction this year. On this basis, enterprises will also adjust the printing patterns in their products according to different fashion trends in each quarter.[consumers gradually love soft jeans]In traditional denim, stiffness, ruggedness and wildness are the basic characteristics of its hand feel. Coarse yarn, high density, heavy weft beating and rigid finishing are the inevitable requirements of traditional denim production. Some people even think that the produced jeans can "stand naturally on the ground" is the best denim effect. However, the prevailing trend of "leisure and comfort" also makes Cowboys deviate from the original characteristics. Consumers put forward higher requirements for the softness and comfort of cowboy fabrics. Denim fabric is soft, comfortable, skin friendly and does not lose the characteristics of denim. It has become a new development direction of denim fabric.In fact, Zhixing textile is far from the only one who has changed the characteristics of traditional denim fabrics. Zaozhuang Haiyang Dynasty Textile Co., Ltd. is also such an innovator. Wang Fang, the sales manager of the company, said in an interview with the reporter of textile and garment weekly that through the use of design and various processing means, the denim fabric brought to the Intertextile autumn and winter flour accessories exhibition not only has the current popular soft and comfortable characteristics, but also has the unique "charming" characteristics of denim fabric.Through the understanding of the above contents, I wonder how much you have absorbed the above knowledge now? I hope that through the study of these contents, you can know more about jeans fabric.

Denim should be very familiar to everyone. Jeans are the most commonly seen. It can be said that there are a few in everyone's wardrobe. Jeans can enter thousands of households, mainly due to the three advantages of denim fabric, one is wear-resistant and more flavor, the other is versatile and not pick people, and the other is moisture permeability and comfort. Today, Xiaobian will tell you why denim has these advantages and how to buy high-quality denim.What is denim?Denim is generally made of cotton yarn, twill weave and yarn dyed process. It belongs to a kind of cotton twill. If you carefully observe the denim, you can clearly see the oblique grain. Now denim fabrics are also developed into cotton, wool, silk, hemp and chemical fiber blends, but they are mainly cotton, cotton polyester blends and cotton ammonia blends. The higher the spandex content, the better the elasticity.Due to the different yarn thickness and textile density, denim can be divided into light, medium and heavy. The light fabric weighs 200-340g per square meter, the medium fabric weighs 340-450g per square meter, and the heavy fabric weighs more than 450g per square meter. The heavier the fabric, the thicker the fabric, and the better the wear resistance and firmness.Characteristics of denimMoisture absorption and air permeability: because denim is usually woven with cotton or yarn with high cotton content, it has the excellent characteristics of moisture absorption, air permeability and comfort.Wear resistance: the yarns used in denim are less than 20, the yarns are relatively thick, and the textile is relatively tight, so the firmness and wear resistance of the fabric are relatively good.The older the denim, the more it tastes: this characteristic of denim is mainly because its yarn dyeing process is different from that of other fabrics. In general, yarn dyed weaving is to soak the yarn in the dye so that the dye can penetrate into the yarn, while denim yarn uses a process called "indigo dyeing". In other words, it only dyes the surface of the yarn, Moreover, Indigo is a non solid color. With wearing and constant friction, the indigo on the surface will gradually fade, and the white yarn will slowly appear. So the more white jeans go through, the more delicious they go through. Some jeans have many white places when they are bought because the manufacturer deliberately whitens them, mainly to create an old style, and some are woven into white yarn.And all kinds of clothes: there are two main colors of denim, one is black (with a little white in black) and the other is indigo (with a little white in blue). Black and white belong to colorless, which is harmonious with clothes of any color. Indigo can be said to be a color that kills the trend circle, that is, it is fashionable no matter how you wear it.These characteristics of denim cast the advantages of denim, which is also the reason why it can be loved by the public.How to buy good denim1. Look with your eyes. Good denim fabric, whether on the front or back, must be very fresh, with clear lines, uniform and straight lines, closely arranged, without too many black spots and other flying impurities. The white yarn will be slightly yellow, and those pure white with reflection must be polyester chemical fiber. If sand washing is done, there will be a nostalgic effect, and the weft on the bottom will appear yellow, which is also normal.2. Touch it with your hand. Hand touch is mainly to feel the fit and texture of denim fabric by hand. When touching, you should not only pinch with your fingers, but cover the jeans with your whole palm and slide up and down repeatedly, so as to deeply feel the fitness of the fabric. A good denim fabric should be smooth without roughness.When touching with your hand, it doesn't mean that the softer the better. The yarn count of denim is not high, so it can't be very soft. Some high-grade denim will be hard because the yarn is arranged too closely, and the denim with high twist and good firmness will also be hard. Those very soft denim are basically treated with softener or liquid ammonia in the washing process. Generally speaking, denim fabric should rely on its own natural characteristics to achieve a close fitting style. If it relies too much on chemical treatment to achieve soft effect, it is actually unfavorable to the texture of the fabric and human health.Black Denim3. Smell with your nose. Smell close to the fabric. Good denim fabric should not have any irritation or other chemical odor. Those with special odor are caused by excessive chemical treatment.Through the three steps of eye observation, hand touch and nose smell, I believe you should be able to preliminarily judge whether a denim belongs to a good fabric. In addition, good denim fabrics should not only achieve beautiful appearance, comfortable fit, wear resistance, moisture absorption and perspiration, and wrinkle resistance, but also fully reflect the style that the more washed the denim is, the more old the denim is, and the more delicious it is.Little knowledge: those cowboy libraries that make particularly fancy or label decorations are often not good cowboy fabrics. The main purpose of businesses is to use these to attract the attention of buyers, so as to reduce the attention of buyers to fabrics. Good cowboy libraries are often simple in style.

What is denim knowledge? Jeans is a very special kind of clothing. Its main feature is that it has a long service life, and the product value is increasing with the increase of service life. The more washed, the more beautiful, the older, the more delicious, which is the remarkable feature of jeans different from ordinary clothes. To achieve this goal, the texture of the fabric is undoubtedly very important. Jeans with poor fabric not only have short product life, are uncomfortable and uncomfortable to wear, but also are easy to deform and fade.At the same time, the added value of jeans is often reflected by washing, and the quality and effect of washing completely depend on the texture of fabrics. Without good fabrics, it is impossible to make a very high-grade washing effect. It can be said that the grade of jeans is largely determined by the grade of fabrics. Real jeans are made of 100% cotton fabric, and even their seams are cotton. Polyester blended fabric can also be used instead of cotton, but it is not very popular, but there are many kinds of fabrics used in luggage. The most commonly used dye is synthetic indigo. Traditional rivets are made of copper, but zippers and buttons are mostly made of iron. The sign is made of fabric, leather or plastic. It can also be in the form of cotton thread embroidery on jeans.At present, the popular trend in the market is to use environmentally friendly colored cotton as raw materials. Scientist Sally fox grows a lot of natural green and brown cotton on her farm in Arizona. She hopes to grow yellow, red and gray cotton one day, but it can't be blue (this color chromosome can't be found in cotton). Generally speaking, cotton is colored by bleaching and dyeing, but the advantage of fox cotton is that it does not need bleaching and dyeing. Therefore, the processing process of this raw material will not produce substances harmful to human body, and its robe will not fade due to washing.The reason why denim ready-made clothes can survive for a hundred years is not the changes in style design and production process, but the ever-changing finishing process. Often the denim clothing produced by the same batch of orders, different washing methods will produce different appearance effects, and the reaction of putting into the market in different periods will be different. In other words, the most important link to determine the style effect of denim ready-made clothes is not in the design department and production department, but in the finishing and washing department. Of course, there are many kinds of denim fabrics, which we will introduce below.
