What is the difference between regenerated fibers and Lesel fibers?
Which is the international fiber artificial and synthetic fiber Standard Bureau of collectively by organic solvent spun cellulose fiber, only a few countries in the world to master this new fiber production technology, the global annual production capacity of 150 thousand tons but, there is no domestic industrial production.
Lesel (Lyocell) fiber, commonly known as "Tencel", with natural plant fiber as raw material, in the middle of 1990s was known for nearly half a century of man-made fibers in the history of the most valuable products.Which fiber is a new textile and apparel fabrics, in late 1990s the rise in europe. It not only has the natural fiber cotton comfort, feel good, easy to dye and other characteristics, but also has the traditional viscose fiber does not have the advantages of environmental protection. Viscose fiber takes petroleum as the raw material, in the production process will release the carbon disulfide, the hydrogen sulfide and so on harmful gas, pollutes the environment, therefore is gradually eliminated in the developed country. Which fiber formed by renewable bamboo and wood pulp as raw material after crushing, advanced technology makes the solvent recovery rate as high as 99.7%, not only energy saving and environmental protection, and sustainable development. Made of this fiber clothing not only natural luster, feel smooth, high strength, no shrinkage, and moisture permeability, good air permeability, and good effect of wool fabric.
The development of regenerated cellulose fiber can be divided into three stages on the whole, forming the three generation products. The first generation was the ordinary viscose fiber, which was released in the early twentieth Century to solve the cotton shortage. The second generation was started in 1950s to realize industrialized production of high wet modulus viscose fiber, its main products include Japan R & D toramomen (named Polynosic) and the change of American R & D high wet modulus fiber HWM and Lenzing Co in late 80s by the new process of production of Modal fiber. In late 60s, due to the rapid development of synthetic fiber production technology, low cost and adequate sources of raw materials, synthetic fibers have greatly affected the market position of regenerated cellulose fiber. Many research institutions and enterprises to pay more attention to the development and application of new synthetic fiber. During this period, the development of regenerated cellulose fibers in the world tended to be stagnant. Third generation products are introduced in 1990s staple fiber Tencel (Tencel), filament Newcell as a representative. Influenced by the awareness of health and environmental protection, nature and other factors, people have a new understanding of the physicochemical properties of regenerated cellulose fiber, a new generation of regenerated cellulose fibers has been fully improved, therefore, the application of regenerated cellulose fibers of the re emergence of rapid development.
