Description
Rayon produced from cellulose dissolved in sodium hydroxide, then treated with carbon disulfide to form an orange viscous solution of cellulose xanthate (viscose). The process for making viscose was discovered in 1892 by Charles Cross and Edward Bevan in England. Soon after the turn of the century, several companies began manufacturing viscose rayon and it quickly became the most important natural polymer fiber. Viscose has good washability and fair abrasion resistance. It dyes well and has good sunlight resistance. It is dyed with direct dyes at low temperatures. Viscose rayons are used for woven and nonwoven fabrics, rubbers, felts, tire cords, and cellophane.
See also rayon.
Synonyms and Related Terms
cellophane; rayon; viscose; Avtex; regenerated cellulose; artificial silk; wood silk; kuntsilke (Dan.); Kunstseide (Deut.); Viskosefasern (Deut.); viscose (Fr.); rayon viscosa (It.); rayon (Ned., Sven.)
Other Properties
Insoluble in most organic solvents. Viscose fibers have continuous lengthwise striations. Cross sections were originally circular with indentations; now may be dog bone or trilobal. Tenacity = 2.0-2.6 g/denier (dry); 1.0-1.5 (wet); Moisture regain = 11-16.6%; Elongation = 15-13%; (dry); 20-40% (wet)
Burns with small flame, incandescent ash and odor of burnt paper.
