Tencel (TM) is the brand name for a cellulose fiber made by Courtaulds from wood pulp. It is assigned to a new generic class "lyocell." Tencel is stronger than cotton or regular viscose rayon and does not lose strength when wet as viscose rayon does. Tencel stretches more than cotton, but less than viscose. It is often blended with cotton and/or polyester, mainly in woven fabrics, rather than knits. It is absorbent and comfortable for wear in conditions of high humidity because it is cellulosic. It is manufactured by solvent spinning, but the solvent is recycled so that Courtaulds claims its manufacture is an environmentally friendly process compared to other rayons. The spinning process results in a round filament fiber with a smooth surface, but it can have a bright luster or matte finish.
