Lyocell fiber

Tencel fiber is the trade name of the first generation regenerated fiber produced by the British company COUR TAULDS, with the scientific name Lyocell fiber. Its production process does not pollute the environment, does not damage the ecology, has a soft hand feel, high moisture absorption rate (11%), and similar dry and wet strength, resulting in good dimensional stability of the fabric. Lyocell fibers are made from wood pulp, which is also fast-growing wood, indicating good recyclability of the raw materials. During the manufacturing of Lyocell fibers, organic solvents containing N-methylmorpholine are used to dissolve lignin. Solvent spinning is a closed process route, and the organic solvents containing N-methylmorpholine are harmless. When Lyocell fibers and their fabrics are discarded, they can be biodegraded and decomposed into carbon dioxide and water. Lyocell fibers are divided into two categories: standard Tencel fibers (with microfibrilization) and Tencel A100 fibers (without microfibrilization), both of which have properties such as softness, toughness, anti-static, good wrinkle recovery, and comfortable elasticity.

2、 Polylactic acid fiber

The raw material of polylactic acid fiber is corn. In fact, fibers made from corn include corn protein fiber, corn lactic acid fiber, corn polypropylene fiber, etc. In 1989, Japan's Zhongfang and Shimadzu cooperated to develop corn polylactic acid fiber. In 1994, they developed a fiber called Lactron. Then, in 1997, the American CDP company fully developed corn polylactic acid fiber and formed industrial production, making polylactic acid fiber a new era green fiber in the textile production field.

Polylactic acid fiber has similar crystallinity, transparency, and heat resistance to polyester fiber. Its spinning method adopts melt spinning, which has low cost and less environmental pollution. Polylactic acid fiber (PLA) has high heat resistance and strength. Although it cannot be flame retardant, it has a certain degree of self extinguishing, good elasticity recovery and curl retention, and good morphological stability and wrinkle resistance. PLA is made entirely from plants, making it a renewable green fiber. Additionally, due to its ability to be degraded by microorganisms into carbon dioxide and water in nature, it is also an environmentally friendly fiber.

3、 Soy protein fiber

Soy protein fiber is a type of soybean plant protein synthetic silk. First, soybean meal is soaked and separated to obtain pure spherical protein. Then, functional additives are added to change the spatial structure of the protein, and under appropriate conditions, it is grafted and copolymerized with hydroxyl polymers to produce soy protein fiber through wet spinning. The fiber properties are stabilized by acetalization treatment. The process of using soybeans or waste soybean meal to produce fibers from soy protein fiber is pollution-free, while fully utilizing waste resources. Soy fiber is a biodegradable regenerated fiber with good physical, mechanical, and chemical properties.
