Classification of denim fabrics

Classified by raw material composition

Denim can be divided into pure spinning denim and blended denim according to the composition of raw materials. At first, it was mainly made of pure cotton. Later, in order to improve the performance of pure cotton denim, some other chemical fibers were added, such as polyester, acrylic, vinylon and viscose fibers. In particular, spandex was added to improve the elasticity of denim clothing and made of

Elastic denim is all the rage. In recent years, in order to expand the types and special needs of denim clothing fabrics, wool, cashmere, silk, hemp and other fibers are also used to develop non-cotton denim fabrics with denim style.

Different classifications of spinning methods

All denim fabrics are made of ring-spun cotton thread. With the continuous advancement of spinning technology and the emergence of various new spinning methods, more and more yarn patterns are used on denim, which can be single yarn, strand yarn, filament or even multi-strand yarn. In addition, various fancy threads are used for denim decoration and embellishment, enriching the variety of denim

Class. In the existing spinning system, it can be broadly divided into ring spinning and rotor spinning. Ring spinning is a traditional spinning method, which relies on the high-speed rotation of the spindle to drive the high-speed rotation of the steel hook to realize twisting and winding. Ring spinning has wide adaptability to fibers and high yarn strength, but there are many hairs in the yarn. Spinners

Long art and low production efficiency. Siro spinning and compact spinning actually only improve ring spinning. Rotor spinning is a new type of spinning method that uses the rotation of the air flow to drive the fibers to rotate, so that the fibers are twisted, and then the twisted yarn is wound out through a winding mechanism. Rotor spinning can realize short process, large roll production,

High production efficiency, but poor adaptability to yarn count. Most of them can only spin medium and low count yarns. Due to insufficient carding, fiber parallelism is low, single fiber strength utilization is low, and yarn strength is low. Rotor spinning, air-jet spinning, and vortex spinning are actually air spinning.

Classified by knitting method

Traditional denim fabrics are mainly woven. Warp yarns are dyed dark blue first, then black and other colors, and then interwoven with natural weft yarns into single-sided left and right twill fabrics of "two up and one down" or "three up and one down", or double-sided left and right twill fabrics of "two up and two down" and "three up and three down". Classified by appearance style

The style of denim clothing sometimes depends on the style of denim fabrics. They complement each other and are greatly influenced by the popularity of consumption. Most denim has a bold, strong and exaggerated appearance, but also has delicate, colorful and delicate special effects. In the past, denim fabrics were influenced by the popularity of clothing, and the varieties and styles gradually diversified, such as denim fabrics such as plaid, jacquard, bump, and color ribbon.
