  • n. A semisynthetic fibre (and associated fabric) made from wood pulp


From a trademark. (Wiktionary)


  • Because the manufacture of viscose rayon which constitutes 95 percent of the rayon currently marketed has always been a highly polluting process, the pressure of environmentalism has led to the introduction of a new rayon fiber, under the brand name Tencel and the generic name lyocell, that is now being promoted as environmentally favorable or low-impact.


  • It turns out that Tencel is a brand name for a fiber called lyocell which is made of the cellulose found in wood pulp.

  • Tencel it is also known as lyocell and is made out of wood pulp.


  • Among the many products that have already earned the label are Procter & Gamble's Gillette ProGuide Fusion razor package; Papermate mechanical pencils, made from Mirel biodegradable plastic; the Greenware line of cold cups, made from NatureWorks' plant-based Ingeo polymer; and intermediates such as Lenzing's TENCEL lyocell fiber, made from eucalyptus, and DuPont's Sorona polymer.

  • This was extremely useful as many of us are familiar with eco-fibers like bamboo, hemp, organic cotton or wool, and soybean, but are less familiar with abaca, lyocell, mud silk, sasawashi, or peace silk, for example.

  • Like all rayon, lyocell is made of cellulosic polymers derived from wood pulp, which is a renewable resource that uses little fertilizer or pesticides.


  • The so-called natural fibers (cotton, linen, silk, wool, ramie, hemp) and the cellulosic man-made fibers (rayon and lyocell) are all absorbent and hydrophilic or water-attracting.

  • But lyocell is said to be taken from sustainably harvested tree farms; and, unlike conventional rayon, it is made in a solvent spinning process that is “close-looped,” meaning that the dissolving agent is used over and over rather than being discarded as waste with each new batch.


  • Hydrophilic fibers all the natural fibers and rayon and lyocell absorb both oily and water-soluble soils, but since they also absorb water and detergent very readily, they tend to give up both types of soil easily too.
