the introduction of viscose
Viscose fiber is a regenerated cellulose fiber. It is based on natural cellulose as raw material, through alkalization, aging, sulfonation and other processes to make soluble cellulose sulfonate, and then dissolve in dilute alkali to make viscose, made by wet spinning. Ordinary viscose fiber, high wet modulus viscose fiber and high strength viscose fiber can be obtained by different raw materials and spinning process. Common viscose fiber has general physical mechanical properties and chemical properties, and cotton, wool and filament, commonly known as rayon, rayon and rayon. High wet modulus viscose fiber has higher polymerization, strength and wet modulus. This kind of fiber can bear 22.0cN load per unit linear density in wet state, and the wet elongation under this load is not more than 15%, mainly rich and strong fiber. High strength viscose fiber has high strength and fatigue resistance.
Viscose fiber is one of the earliest chemical fibers put into industrial production. Because of good hygroscopic, comfortable to wear and good spinnability, it is often blended with cotton, wool or various synthetic fibers, interwoven, used in all kinds of clothing and decorative textiles. High strength viscose fiber can also be used for tire cord, transport belt and other industrial supplies. Viscose fiber is a kind of widely used chemical fiber.
