The Difference Between Lyocell Fiber And Tencel

Lyocell fiber belongs to the third generation of regenerated cellulose fiber.

The development of regenerated cellulose fibers can generally be divided into three stages, forming three generations of products.

The first generation was the common viscose fiber introduced in the early 20th century to solve the shortage of cotton.

The second generation is the high wet modulus viscose fiber that began to achieve industrial production in the 1950s, and its main products include the tiger Kapokay developed in Japan (later named Polynosic) and the variable high wet modulus fiber HWM developed in the United States, and the Modal fiber produced by Lenzing Company in the late 1980s using a new process. Since the late 1960s, due to the rapid development of synthetic fiber production technology, sufficient raw material sources and low cost, synthetic fibers have greatly impacted the market position of recycled cellulose fibers. Many research institutions and enterprises pay more attention to the development and application of new synthetic fiber. During this period, the world's development of recycled cellulose fibers has stalled.

The third generation of products is represented by the short fiber Tencel and filament Newcell introduced in the 1990s. Under the influence of health and environmental awareness, advocating nature and other factors, people have a new understanding of recycled cellulose fibers, and the physical and chemical properties of the new generation of recycled cellulose fibers have also been fully improved, so the application of recycled cellulose fibers has re-emerged a rapid development.

Lyocell fiber, commonly known as "tencel", with natural plant fiber as raw material, came out in the mid-1990s and is known as the most valuable product in the history of man-made fiber for nearly half a century.

Lyocell fiber is a new kind of textile and clothing fabric, which rose in Europe and America in the middle and late 1990s. It not only has the characteristics of comfort, good hand feel and easy dyeing of natural fiber cotton, but also has the environmental protection advantages that traditional viscose fiber does not have.

Lyocell fiber with renewable bamboo, wood and other pulp formed after crushing as raw materials, advanced technology makes its solvent recovery up to 99.7%, not only energy saving, environmental protection, and sustainable development. The clothes made of this fiber not only have natural luster, smooth feel, high strength, basically no shrinkage, but also have good moisture permeability and air permeability, and the fabric blended with wool has a good effect.

Lyocell fiber is the international man-made and synthetic fiber standards Bureau of cellulose fiber through organic solvent spinning process collectively, at present, only a few countries in the world have mastered the production technology of this new fiber, the global annual capacity of only 150,000 tons, the domestic has not yet industrialized production.
