Viscose fibers are obtained from wood of beech, spruce, bamboo, and other woods. The contained cellulose is extracted, and a spinning mass is produced. When the correct viscosity is reached, the viscose fiber is produced by spinning nozzles. The regenerated cellulose is chemically identical to the native fiber cellulose, such as cotton, but has a different elementary lattice in the ordered areas. By modifying the production parameters and the aftertreatment, viscose fibers can be adapted very well to the intended processing and use, e.g. highly crimped, highly wet-strength, color-fast spun-dyed and flame-retardant fibers.
Different crimps and cut lengths make blends with cotton or wool possible, but also used alone there are many applications such as the dressing industry, tamponages, hospital textiles and hygiene. Smooth filaments are used in cord fabrics for tire carcasses, conveyor belts, injection molding reinforcement, filter media for food and other applications.
