What is a new type of recycled fiber?
Modal fiber is a new kind of cellulose fiber. The raw material of Modal fiber comes from the wood of nature. It can be degraded naturally after use. Because of this kind of fiber is made of natural cellulose as raw material is biodegradable, serious environmental pollution problems and produce similar viscose fiber in fiber production process, is a new environmental protection fiber, twenty-first 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 play their respective characteristics of fiber, to achieve better effect. Modal fabric has better moisture absorption and breathability than pure cotton fabric. It has a soft feel, good drape, comfortable wearing and bright color. It is a kind of natural mercerized fabric.
Soybean protein fiber is out of oil after the soybean dregs as raw material, the use of biological engineering technology, the soybean meal ball in protein purification, and through the role of biological enzyme, the purified globulin change spatial structure, then add hydroxy and amino polymer, preparation of protein spinning solution concentration, spinning a wet spinning process. Soybean meal is a by-product of the oil workshop. It is rich in resources in China and belongs to the comprehensive utilization of waste. The resources are inexhaustible. Soybean protein fiber can be called "green fiber" in the new century". Because the outer layer of soybean protein fiber is basically protein, and has good affinity with human skin, and contains many kinds of amino acids required by human body, and has good health care function. Chinese herbal medicine and protein side chain adding quantitative in the spinning process of soybean protein fiber in the bactericidal anti-inflammatory effect by combination of chemical bond, significant efficacy and lasting, avoid functional cotton products finishing method developed products, the effect is difficult to continue the disadvantages. The soybean protein fiber fabric feels soft and smooth, has good moisture absorption and breathability, has silk like luster, crease resistance is superior to silk, and the dimension stability is good.
Tencel fiber is mainly coniferous wood pulp, water and solvent mixed amine oxide, heating to dissolve completely, any derivatives and chemical effects will not occur in the dissolution process, the impurity and direct spinning, its molecular structure is simple carbohydrates. Tencel fiber can be completely decomposed in the soil, no pollution to the environment; in addition, used in the production of amine oxide solvent completely harmless to the human body, almost all of the recovery, can be used repeatedly, in the production of raw materials of pulp cellulose molecules contained no chemical change, no by-products, no waste discharged outside the factory, can be called for the environmental or green fiber. The fabric has excellent moisture absorption, comfort, drape and stiffness and good dyeing, and can be blended with cotton, wool, linen, acrylic, polyester etc., can ring spinning, air spinning, core spun spinning, spinning into various cotton core spun yarn and Mao Xingsha, etc..
As a textile raw material, regenerated fiber has excellent moisture absorption and comfortable wear. It is one of the most ideal and most promising textile materials in the textile and clothing industry. In recent years, in the textile production, in addition to the use of viscose fiber, but also used. Tencel fiber, Modal fiber, soybean protein fiber, bamboo fiber and viscose chitin fiber as a new generation of regenerated fiber, in order to develop production and choose to use a new regenerated fiber fabrics, it is necessary to understand the new types of regenerated fiber and discriminant analysis.
Tencel fiber, Modal fiber, soybean protein fiber, bamboo fiber and viscose chitin fiber, and compared the physical properties of these 5 kinds of new regenerated fiber and viscose, cotton, silk, wool and fiber; method of identification of these new regenerated fiber were studied, using microscope identification, then with dissolution method, to verify the combustion method and coloring method.
