Lycocell fabric and its production and characterstics

Textile lycocell and its characteristics and production

1. LYOCELL Lyocell is a semi-synthetic fabric that is commonly used as a substitute for cotton or silk. This fabric is a form of rayon, and it is composed primarily of cellulose derived from wood.

3. HISTORY The development of Tencel was motivated by environmental concerns; researchers sought to manufacture rayon by means less harmful than the viscose method. The Lyocell process was developed in 1972 by a team at the now defunct American Enka fibers facility at Enka, North Carolina. In 2003, the American Association of Textile Chemists and Colorists (AATCC) awarded Neal E. Franks their Henry E. Millson Award for Invention for Lyocell. In 1966–1968, D. L. Johnson of Eastman Kodak Inc. studied NMMO solutions. From 1969 to 1979, American Enka tried unsuccessfully to commercialize the process. The operating name for the fiber inside the Enka organization was " Newcell ", and the development was carried through a pilot plant scale before the work was stopped. 6/22/20XX 3

4. PROPERTIES Fibrillation of Lyocell may produce a "peach-fuzz" feel. Lyocell shares many properties with other fibers such as cotton, linen, silk, ramie, hemp, and viscose rayon (to which it is very closely related chemically). Lyocell is 50% more absorbent than cotton, and has a longer wicking distance compared to modal fabrics of a similar weave. Compared to cotton, consumers often say Lyocell fibers feel softer, and "airier", due to their better ability to wick moisture. Industry claims of higher resistance to wrinkling are as yet unsupported. Lyocell fabric may be machine washed or dry cleaned. It drapes well and may be dyed many colors, needing slightly less dye than cotton to achieve the same depth of colour . 4 6/22/20XX
