Cellulose as a raw material, the structure of cellulose II recycled fibers. Due to the reduction of arable land and the depletion of petroleum resources, the production of natural fibers and synthetic fibers will be increasingly constrained; people are paying attention to the value of regenerated cellulose fibers while paying attention to the environmental performance of textile consumption. Know and discover. The application of regenerated cellulose fiber has now obtained an unprecedented opportunity for development. The development of regenerated cellulose fibers can be generally divided into three stages, forming three generations of products. The first generation was the ordinary viscose fiber that was introduced in the early 20th century to solve the cotton shortage. The second generation is a high-wet-modulus viscose fiber that began industrial production in the 1950s. Its main products include Japanese-developed tiger kapok (later named Polynosic) and the United States developed and developed high-modulus fiber HWM and blue The company's Modal fibers produced in the late 1980s using a new process. Since the late 1960s, due to the rapid development of synthetic fiber production technology, abundant sources of raw materials and low cost, synthetic fibers have greatly impacted the market position of regenerated cellulose fibers. Many research institutions and companies pay more attention to the development and application of new synthetic fibers. During this period, the development of the world's regenerated cellulose fibers has stagnated. The third-generation products are represented by staple fiber Tencel and filament Newcell launched in the 1990s. Affected by health and environmental awareness and advocacy for nature, people have a new understanding of regenerated cellulose fibers, and the physical and chemical properties of the new generation of regenerated cellulose fibers have also been fully improved. Therefore, the application of regenerated cellulose fibers has reappeared. Rapid growth. According to reports, the total synthetic fiber production in the world in 2005 was 34.6 million tons, a decrease of 0.30% compared to the 34.7 million tons in 2004. However, there has been a significant increase in the production of regenerated cellulose fibers. According to statistics, the total production capacity of regenerated cellulose fibers in the world was 2.264 million tons in 2003, which was 2.463 million tons in 2004, and reached 292.7 in 2005. Million tons, in 2006 the total amount of global regenerated cellulose reached 3.4 million. 1.Tencel fiber Tencel fiber, also known as "Tiansi", recently also known as "Lyocell (Lyse)." Coniferous wood pulp, water, and solvent amine oxide are mixed and heated to complete dissolution. No derivative and chemical reactions are produced during the dissolution process. Spinning is performed by impurity removal and the molecular structure is simple. Compound. Tencel fiber can be completely decomposed in soil and has no pollution to the environment; in addition, the amine oxide solvent used in production is completely harmless to the human body and can be recovered almost completely. It can be used repeatedly, and the cellulose molecules contained in the raw material pulp are produced. No chemical change, no by-products, no waste discharged outside the plant, environmental protection or green fiber. The fiber fabric has good hygroscopicity, comfort, drapability and stiffness and good dyeing property, and can be blended with cotton, wool, hemp, nitrile, polyester, etc., and can be ring-spun, air-spinned, and core-spun. Spun into a variety of cotton and wool yarn, core yarn and so on. Therefore, the fiber can be used not only in the production of underwear fabrics, but also in the use of fabrics for outerwear garments. 2. Modal fiber Modal fiber is also known as “Modal†and “Modalâ€. It is a brand new cellulose fiber. The raw material of Modal fiber comes from nature's wood and can be naturally degraded after use. Because this type of fiber uses natural cellulose as a raw material, has biological decomposability, and does not produce serious viscous fiber-like environmental pollution during fiber production, it is a new type of 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 fibers can be blended and interwoven with a variety of fibers to give full play to the characteristics of their fibers and achieve better results. Modal fiber fabric has better moisture absorption and breathability than pure cotton fabrics. Its soft hand feeling, good drape, comfortable wear, and bright color are natural silk fabrics. Because of its comfortable fabric, good elasticity, and good breathability, modal fabrics are used by many well-known underwear brands such as Septwolves, Elites, David archy, etc., and more and more domestic consumers love Modal underwear. But because of these characteristics, modal fabrics are used less in garments because it is more difficult to achieve the effect of shaping. 3. Bamboo fiber Bamboo fiber is a new type of regenerated cellulose fiber developed and industrialized by our country after soybean protein fiber. Bamboo fiber is divided into bamboo fiber and bamboo fiber. Bamboo fiber is made of bamboo as a raw material, and is added with a functional aid in bamboo pulp and processed by wet spinning. Bamboo fiber is a fiber obtained by treating bamboo with natural biological agents. Bamboo pulp, which is a raw material for spinning, is derived from fast-acting fresh bamboo and is rich in resources. The buried and incinerated litter will not cause environmental pollution. It is an environmentally friendly fiber and meets the needs of green consumption. Bamboo fiber is similar in performance to viscose fiber. Bamboo fiber fabric has good moisture absorption and air permeability. Its drape and dyeing properties are also relatively good. It has silky luster and feel, and it has antibacterial, deodorant and anti-ultraviolet functions. These natural characteristics of bamboo fiber make it an exclusive seat in the textile of personal clothing fabrics. With the healthy and naturalized concept of consumer spending, bamboo fiber has been sought after by major underwear manufacturers. 4. Viscose-based chitin fibers Chitin is widely present in the shells of arthropods such as aquatic products such as shrimps and clams and insects, and is also present in the cell walls of fungi and algae. Viscose-based chitin fibers are fibers made by mixing a mixture of chitin, chitosan, and cellulose through a conventional wet spinning process. It has biological activity, biodegradability and biocompatibility, and has excellent moisture absorption and moisturizing function. The deodorizing function of fabrics made of chitin fibers mixed with cotton has broad prospects for application in the development and application of health apparel. In short, all fibers that are recycled using cellulose as raw material can be called regenerated cellulose fibers.
