The Type of Sheet Mask(non-woven)-Cupra

* Cupra side *

What is ?

__

It was invented by French Dispaisys in 1890 and started production in 1895 by the Germans Bronnell. In 1918, Schoenberg of Germany adopted a new spinning method to produce a yarn thinner and taller than viscose rayon. The trademark is called Bemberg.

How made ?

__

The process is made by cotton linters (short fibers sampled from cotton) as raw materials, dissolving them in ammonia solution of copper oxide (copper oxide), and threading them by tension spinning. It is called cuprammonium rayon according to the characteristics of this process. It belongs to the fiber regenerated fiber and has the characteristics similar to viscose rayon, but it can make yarn thinner and tighter than it, and it is also close to the elegant luster and soft texture. It is used in thin fabrics, blouses, dresses, underwear, lining and so on because it does not change so much even when wetted with water.

Why good? or bad?

* Cupra cross section *

1. Beauty-like rayon

The cross-section of the fiber is of a garden type, has a beautiful luster and has a nuts-like appearance.

2. Good skin feel

Because the texture of the cupra is similar to the nuts, the texture of the skin is soft. Also, the fibers are thin and smooth.

3. It is strong

Compared to similar fibers, it is quite strong. Particularly, even when wet, there is little drop in strength, and light resistance and abrasion resistance are superior to rayon. There is a characteristic common to the regenerated fibers that they are excellent in hygroscopicity and dyeability.
