Viscose fiber can not only supplement the shortage of natural fibers in quantity, but also is superior to conventional synthetic fibers in some aspects of its properties, so it has a wide range of uses.
1. the civil viscose fiber can be spun pure and blended with cotton, wool, hemp, silk and various synthetic fibers. The fabric is fine and soft, with smooth feel, good air permeability, comfortable in wearing, bright color after dyeing, and suitable for underwear, coat and various decorative fabrics. In addition, it is also widely used in the manufacture of nonwoven fabrics.
2. the industrial and other aspects of viscose fiber have many industrial uses. Viscose fiber strength silk has high strength, good heat resistance and low price. It has an important position in tire, pressure hose, conveyor belt, canvas, coated fabric and other industries. The hemostat, gauze, bandage and medical sheets, clothing, artificial kidney and blood dialysis device made of viscose fiber are widely used in the medical and health department. General use; mixed with pore forming agent in viscose. The formed fiber contains a large number of micropores and large surface area. It has good dyeability, high water absorption and can be used as filter cloth, mask and gas mask. It can also be used as a cigarette filter. Because of its high water retention rate, it can be used for medical, health, health care products and so on. The adhesive fiber with acrylic acid has a high ion exchange capacity, which can be used for air purification, sewage purification, or the collection of trace radioactive elements and rare and precious metals from the waste liquid, and the carbonization of viscose fibers to high strength and high modulus carbon fibers. It is the aviation, aerospace, military industry and many high-tech departments. It is necessary to strengthen the material; graphite is mixed into viscose, and the graphite fibers made from it can be used as industrial sealing materials. The graphite viscose fiber developed by Austria Lenzing is used for gas seals and rollers, with a temperature range of up to 200 degrees centigrade.
