Viscose Rayon Staple Fiber Flame Retardant For Disposable Hygiene Products

3. Production of viscose fiber

Viscose is a biodegradable material made from natural wood cellulose. The journey starts from renewable tree plantations where trees have an average harvesting cycle of 5 years in equatorial climate. These wood logs are then debarked and cut into small pieces of wood chips, which are then processed in large digesters to remove lignin, a glue-like substance that binds fibres together. The end product after a few rounds of filtering and washing is dissolving wood pulp.  

Dissolving wood pulp is further dissolved into a viscous liquid which is then crystallised into regenerated cellulose threads called viscose fibres.  To make soft, silky and absorbent viscose clothing, these fibres are spun into yarns via a process called spinning, which is the twisting together of drawn out strands of fibres. At the end of this process, these yarns are ready to be woven or knitted into fabric to make clothing. To make wet wipes, facial masks and other hygiene products, viscose fibres are bonded together using non-woven technology by entangling the fibres mechanically, thermally and etc.
