Viscose fabrics and applications in the manufacture of compressed paper towels

What is a viscose fabric?

Conventional viscose when not made into fabric they are called rayon, but when they become a rayon fabric will be called viscose, this is a semi-synthetic fabric. Before being clothed, rayon was a liquid like honey that, after being cooled, became solid.

The material used to make fibers is the fiber of regenerated cellulose fibers from trees such as soybeans, sugarcane, bamboo, … Viscose has a structure similar to cotton and is widely used in many fields.

Viscose fabric production process

Step 1: Grind cellulose raw material, then dissolve it in sodium hydroxide solution to form alkaline cellulose. Impurities are removed in the process. To achieve purity, the cellulose ratio must reach 90%.

Step 2: Alkaline cellulose is treated with carbon disulfide to form cellulose natrixanthate. Rayon fibers are then produced from solutions from mineral acids such as sulfuric acid, in this process, the xanthate groups are broken down to regenerate cellulose and release dithiocarbonic acids.

Step 3: The condensate solution is pushed through the extruder to produce viscose fibers. These are called derivative cellulose fibers. The fibers are soaked in sulfuric acid solution then pulled and washed

Step 4: Viscose fiber will be pulled into and weaved into large size fabric for use.
