Introduction To Several Recycled Fibers

Introduction to several recycled fibers

Recycled fiber has excellent moisture absorption and wearing comfort, and is the most ideal and most promising textile raw material in the textile and garment industry.

Overview of recycled fiber:

1.Tencel fiber

Tencel fiber is a combination of conifer-based wood pulp, water and solvent amine oxide, heated to complete dissolution, does not produce any derivatives and chemical effects during the dissolution process, and is directly spun by impurity removal, and its molecular structure is simple. Carbohydrates. Tencel fiber can be completely decomposed in the soil and has no pollution to the environment. In addition, the amine oxide solvent used in the production is completely harmless to the human body, can be almost completely recovered, and can be repeatedly used to produce cellulose molecules contained in the raw material pulp. Can not afford chemical changes, no by-products, no waste discharge outside the factory, is environmentally friendly or green fiber. The fiber fabric has good hygroscopicity, comfort, drape and stiffness and good dyeability, and can be blended with cotton, wool, hemp, nitrile, polyester, etc., and can be ring-spinning, air-spinning, core-spun, Spinning into various cotton and wool yarns, core yarns, etc.

2.Modal fiber

Modal fiber is a brand new cellulose fiber. The raw material of Modal fiber comes from natural wood and can be naturally degraded after use. Because this kind of fiber is made from natural cellulose, it has biological decomposability, and it does not produce serious pollution environment problems like viscose county committee in the fiber production process. It is a new environmental protection fiber in the 21st century. Modal fiber is half the price of Tencel fiber and is the second generation of regenerated cellulose fiber. Modal fiber can be blended and interwoven with a variety of fibers to achieve the characteristics of their respective fibers for better results. Modal fiber fabric is superior to pure cotton fabric in moisture absorption and breathability. It has soft hand feeling, good drape, comfortable wearing and bright color. It is a natural mercerized fabric.

3. Soy protein fiber

Soybean protein fiber is made from soybean waste sputum after oiling, using bio-engineering technology to purify the globulin in soybean meal, and through the action of auxiliaries and biological enzymes, the purified globulin changes the spatial structure, and then adds hydroxyl groups. A polymer such as an amino group is formulated into a certain concentration of a protein spinning solution and spun by a wet spinning process. Soybean meal is a by-product of the grease workshop. It is very commanded in China's resources. It is a comprehensive utilization of waste, and resources are inexhaustible. Soy protein fiber can be called the "green fiber" of the new century. Since the outer layer of soybean protein fiber is basically protein, it has good affinity with human skin and contains a variety of amino acids necessary for human body, and has a good health care effect. In the soybean protein fiber spinning process, a quantitative bactericidal and anti-inflammatory effect of the Chinese herbal medicine and the protein side chain are combined by chemical bonds, and the drug effect is remarkable and long-lasting, thereby avoiding the functional product developed by the post-finishing method for cotton products, and the drug effect is difficult. Consequent shortcomings. Soy protein fiber fabric is soft and smooth, has good moisture permeability, silky luster, wrinkle resistance is better than silk, and dimensional stability is good.

4. Bamboo fiber

Bamboo fiber is a new type of regenerated cellulose fiber developed and industrialized by China after soybean protein fiber. Bamboo fiber is divided into bamboo fiber and bamboo fiber. Bamboo fiber is made from bamboo and is added to the bamboo pulp by functional additives and processed by wet spinning. Bamboo fibrils are fibers obtained by treating bamboo with natural biological agents. Bamboo pulp, which is a raw material for spinning, is derived from the fast-growing fresh bamboo and is rich in resources. The waste soil is buried and burned without causing environmental pollution. It is an environmentally friendly fiber that meets the needs of green consumption. Bamboo fiber is similar in performance to viscose fiber. Bamboo fiber fabric has good moisture absorption and gas permeability. Its drape and dyeing properties are also good. It has silky luster and hand feeling, and has antibacterial, deodorant and anti-ultraviolet functions.

5. Viscose-based chitin fiber

Chitin is widely found in the outer shells of aquatic products such as shrimps, oysters, and other arthropods, as well as in the cell walls of fungi and algae. The viscose-based chitin fiber is a fiber produced by a conventional wet spinning process by mixing chitin, chitosan and cellulose. It is biologically active, biodegradable and biocompatible, and has excellent moisture absorption and moisturizing functions. The use of chitin fiber and cotton blended fabrics to take deodorizing functions has broad prospects for the development of health apparel applications.

Using Tencel fiber, Modal fiber, soybean protein fiber, bamboo fiber and viscose-based chitin fiber with viscose fiber, cotton, silk, wool and polyester fiber by microscopy, dissolution method, combustion method and coloring method respectively
