Hemp fabric design blended raw material selection
Hemp blended chemical fiber fabric has 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 raw materials for blended chemical fiber fabrics 1. Hemp: The raw material used in hemp and other fiber blended chemical fiber fabrics is usually carded hemp (sometimes cut hemp leaves). Due to the unusual structure of hemp, 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 with chemical fiber fabrics, 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 with chemical fiber fabrics, cow velvet can be used to achieve soft luster, good elasticity, soft and smooth feel and UV shielding properties. 3. Tencel Tencel is called the “21st century green fiber” and is a man-made fiber that has been successfully developed 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 finishing and production process. After blending chemical fiber fabrics, Tencel can take advantage of its good luster, high strength and elongation, and good moisture absorption properties. 4. Composite fiber: Composite fiber is an environmentally friendly fiber that uses high-tech means to sort waste plastics through extraordinary processes. The advantages of this fiber are high strength, good length, linear density, and uniformity. When blended with hemp fiber, yak down, and Tencel into chemical fiber fabrics, it can effectively improve the quality of the yarn and improve the wearing performance of the fabric.
