There are many ways to classify denim fabrics, mainly from the raw materials, yarns, weaving, finishing, appearance and so on.
According to the different classification of raw material composition, the raw material composition of denim fabric can be divided into pure spinning and blended spinning. At first, it was mainly pure cotton. Later, in order to improve the wearing characteristics of pure cotton jeans, it was added_ Some other chemical fibers, such as polyester, acrylic, vinylon and viscose fibers, especially spandex, which was added to improve the elasticity of jeans, were once popular. In recent years, in order to expand the categories and special needs of denim fabrics, wool, cashmere, silk, hemp and other fibers are also selected to develop special non cotton denim fabrics with denim style.
According to different spinning methods, the original denim fabrics used ring spun cotton thread. With the continuous improvement of spinning technology and the emergence of various new spinning methods, there are many yarn patterns used in denim fabrics, including single yarn, strand, filament and even compound strand. In addition, various fancy threads are selected for the decoration and embellishment of denim fabrics, enriching the categories of denim fabrics.
According to different weaving methods, the traditional denim fabric is mainly woven. The warp is dyed into dark blue first, and then brown, black and other colors, and then interwoven with the natural weft into single-sided left or right twill weave of "2 up and I down" or "3 up and 1 down", or double-sided left or right twill weave of "2 up and 2 down" and "3 up and 3 down". In order to broaden the variety of denim fabrics, some enterprises have introduced twill changes, twill joint organizations and complex organizations with twill as the theme. In recent years, some enterprises have developed knitted fabrics and denim fabrics with special weaving methods.
In the future, the finishing methods are different. Most of the jeans are dyed and finished, and a few are finished and then made. There are two main types of garment finishing, namely, physical and chemical finishing. The former is such as grinding and sand blasting, while the latter is more and more.The most basic method of denim finishing is to use other washing water, such as general washing, stone washing / stone grinding, sand washing, damage washing, etc. With the progress of science and technology, more and more new washing processes are emerging. Due to the limitations of production conditions, processing costs and regional environmental protection, the washing scale of jeans is also greatly limited. The post-processing of anhydrous jeans will become the direction of development in the future.Nowadays, some denim fabrics are processed after different physical and chemical finishing, such as thread embroidery, discharge dyeing, resin, softness, machine embroidery, hot drilling, glue printing, laser and so on. It is difficult to adapt to different consumer needs with only one washing process. Generally, several processes are used together. Cowboy designers are required to understand the washing process and be able to master it, so as to innovate cowboy clothing to the greatest extent. The ever-changing washing process is also an important reason for the popularity of jeans.
