Rayon- Viscose

There are two types of rayon- viscose rayon and high-wet-modulus (HWM) rayon, categorized on the basis of two principal methods of making rayon. Whatever the method used for making rayon, they are essentially made from cotton linter or wood pulp usually obtained from pine, spruce, or hemlock trees.

Wood chips or cotton fibers are used to make viscose solution, which is forced through a spinneret into sulfuric acid to produce cellulose filaments. After extrusion from spinneret, the viscose rayon fibers are processed to make filament or spun staple yarns through various spinning processes, such as Pot Spinning, Spool Spinning, and Continuous Spinning. Different varieties of yarns such as monofilament yarns, multifilament yarns, spun yarns etc. are made that are further woven into a wide variety of fabrics. Spun rayon yarns can be used for making fabrics similar to cotton, linen or wool. Rayon filament yarns can make fabrics like silk. Various finishes are also applied to these fabrics that give numerous properties to viscose rayon.

Detailed Product Description:
Used in the national defense uniform, extinguishing and protection uniform, special protection clothes and so on.
Flame-retardant viscose staple fiber is the fiber that regularly mixes the N-P complex flame-retardant and viscose solution with the static mixer before weaving. Then the flame-retardant viscose staple fiber is shaped after the acid bath and the processing.
