With the increasing demand for slim and tight styles in the jeans market, the development demand for elastic denim fabrics is also growing. It is reported that around the world, in addition to women's clothing, men's clothing also began to use a large number of elastic denim fabrics, especially overseas large-scale manufacturing and retail (SPA) and international brands. The overall utilization rate of elastic denim fabrics is high.What is stretch denim?In the process of denim production, a certain percentage of elastic fiber is added to the weft, which will have a certain degree of elasticity and comfort. In 1962, cone mills was the first factory in the United States to use and promote elastic denim. Legler (Italy) was the first factory to produce special denim in the late 1970s, although it was not very successful at that time.
In 1978, the earliest elastic jeans were produced by Peter Golding, and Mustang began to produce elastic jeans in 1983. In 1980, Levi's, with the help of lauffenmuhle's elasthenim, began to launch women's stretch jeans in the UK. This initiative has received a good response in the UK, and other brands have begun to follow suit. Marks & Spencer is the second brand to launch elastic jeans, which uses Legler's denim series. In the next few years, probably 1983-1984, elastic fabrics and jeans in Europe flourished.
In the 1990s, the use of lycra elastic fiber began to increase, and elastic denim continued to be popular. However, in this decade, the use of elastic cloth gradually decreased with the popularity of pocket pants and non tight pants. In 1998, some elements of fabrics began to regain popularity, which greatly promoted American manufacturers to produce elastic denim. The revival of super tight jeans in 2006 has become an inevitable trend to increase the output of elastic denim. A large number of contemporary boutique denim include Agave, rock & Republic, chip & pepper and gold sign. They all use modern elastic denim today. Therefore, denim manufacturers began to produce this kind of elastic denim. This kind of cloth has a natural appearance, and the tights made by it are incomparable to its previous generation products. This kind of fabric can be shared by men and women at the same time.
Q: What do 40d, 70D, 200D and 300D mean?A: 40d and 70D represent the specifications of spandex filament. 200D and 300D represent the specifications of weft raw materials.Q: What does it mean if the weft specification has both 40d and 200D? What do 40 and 200 mean? The weft direction is 200D 40d polyester denim.
A: Remember, the larger number in the front is the main polyester yarn, and the 40d or 70D behind is the spandex elastic yarn wrapped in the middle by polyester.High elastic denim fabric
The warp yarn of high elastic denim fabric uses air coated yarn or twist yarn of polyurethane fiber and polyester fiber. With the design of fabric technology, the elongation performance is increased by 40% and the recovery performance after elongation is increased by 30% compared with previous commodities, and the tension is reduced at the same time. At the same time, it can also prevent the deformation of high elastic denim fabric and knee bulge, and maintain the close fitting effect. In addition, the dyeing and finishing process of the fabric is the same as that of general commodities, and does not damage the aging feeling of elastic jeans. The weight of the fabric is about 227 283 grams, and the colors are indigo, black and white for garment dyeing.
Why does elastic fiber spandex bifurcate?First, spandex belongs to chemical fiber, which is obtained by spinning and texturing. When spinning chemical fiber, several single fibers are usually combined together and then wound into rollers. In order to eliminate static electricity and increase the stability and closure of the tow, it is often oiled, that is, the process of adding an oil tanker in the silk road. The chemical fiber without oil will not only bifurcate, but also be easy to damage and fracture. There will also be problems such as floating wire and insufficient strength in post-processing. This is one of them.Second, the machine package may be several chemical fibers wrapped together to make wrapping yarn, which is one of the uses of chemical fiber DTY yarn, such as spandex, nylon, or cotton thread. Under the high-speed operation of the roller, static electricity will be generated by friction between them. Elimination method: first, the humidity of the processing workshop environment can be increased, which is generally controlled at about 60%. Second, you can analyze whether the purchased spandex is not oiled and contact the supplier. Third, check whether your wrapping process is appropriate.
