Hemp fabric design, blended raw material selection and composite fabric information

Hemp blended fabric combines the excellent properties of human hemp and yak hair, and also has the characteristics of high strength and good drape. It is a natural and environmentally friendly fabric that people are pursuing in the 21st century. (1) Selection of blended raw materials 1. Hemp The raw material used for blending hemp with other fibers is usually carded hemp (sometimes cut hemp leaves). Due to the particularity of its own structure, the quality of hemp fluctuates greatly. The main manifestations are large differences in fiber length, high short staple rate, and many super-long and double-length fibers. In addition, hemp fiber has high rigidity, poor cohesion, and small elongation. , easy to break and waiting point, hemp must be pre-treated before use. After blending, hemp can be used to prevent bacteria, mildew, health care, moisture absorption, breathability, antistatic and other properties. 2. Yak velvet is a specialty product on the ancient Tibetan Plateau. The velvet scales are ring-shaped with neat edges and are close to the hair shaft. It has a soft luster, good elasticity, soft and smooth feel, and shields against ultraviolet rays. The length uniformity and linear density uniformity of yak cashmere are poor, and the strength of the medium fiber is low. After blending, cow velvet can be used for its soft luster, good elasticity, soft and smooth feel and UV shielding properties. 3． Tencel Tencel is called the “21st century green fiber” and is the most successfully developed man-made fiber in recent years. It has the comfort of cotton, the strength of polyester, the drape of viscose fiber, and the feel of silk. At the same time, it is pollution-free during its processing and production. After blending, Tencel can take advantage of its properties such as good luster, high strength and elongation, and good hygroscopicity. 4. Composite fiber: Composite fiber is an environmentally friendly fiber that uses high-tech means to process waste plastics through special processes. The advantages of this fiber are high strength, good length, linear density, and uniformity. When blended with hemp fiber, yak hair, and Tencel, it can effectively improve the quality of the yarn and improve the wearing performance of the fabric.
