The Difference Between Three Kinds Of Textile Fibers Lyocell, Tencel And Newcell

Lyocell,

Both Newcell and three kinds of fibers belong to regenerated fiber, which is a new generation of pollution free green fibers.

Because of the serious pollution of waste gas and wastewater caused by the use of CS2 in the production of viscose fibers in the past few decades, the production of this fiber has been restricted by strict environmental protection policies, prompting all countries in the world to devotes themselves to research and develop new fibers to reduce environmental pollution.

Cellulose fibers made from NMMO (N- methyl linoline oxide) are known as green fibers because they are non polluting.

Lyocell, Tencel and Newcell fibers are cellulose fibers made from NMMO, that is viscose fiber.

In 1044, it was named LyMell (CLY) by the international synthetic fiber and synthetic fiber Bureau.

The short fiber is called Tencel, and the filament is called Newcell.

Lyocell has been produced in the United States by Koa Tauer Azee (Courtaldo) since 1993, and its trademark is Tencel.

At present, the main varieties and trademarks of Lyocell fiber produced in the world are shown in the following table.

There are many characteristics: strength, such as nylon, finer silk, polyester washability and breathability of cotton fiber.

It also has fibrinolytic effect, which can produce similar peach fiber surface effects that conventional fibers can not get.

Lyocell fiber is known for its high dry strength and wet strength.

A pilot production line has been formed. It is suggested that the effect of the final product be further verified in practice, compared with the final product of the conventional conventional pretreatment process, for example, the effect of removing pulp, especially the effect of removing PVA pulp, the effect of removing cotton hull and main cotton mixture, the fracture strength damage of Lyocell in wet state is only 6%, and the elongation is almost unchanged.

Its high temperature resistance is good. At 190 30s, the strength of staple is damaged. The strength and strength of 7%oNewcell fiber are very good. The pretreatment technology of bulk fiber dyed products is dyed with colored fibers, especially cotton and other natural fibers, which are easy to block after processing. Therefore, it has many requirements for fluffiness, softness, smoothness and so on, so as to improve its spinnability.

It reaches the level of synthetic fiber and seldom contracts.

The fibrillation degree of Newcell fiber is obviously lower than that of Tencel fiber.

The finishing route of Newcell fabric is pretreatment, fibrillation, enzyme treatment and two fibrillation.

and

The processing route is simpler, and the enzyme treatment and fibrillation process can be omitted.
