Rayon produced from [http://cameo.mfa.org/materials/fullrecord.asp?name=cellulose cellulose] dissolved in [http://cameo.mfa.org/materials/fullrecord.asp?name=sodium%20hydroxide sodium hydroxide], then treated with [http://cameo.mfa.org/materials/fullrecord.asp?name=carbon%20disulfide carbon disulfide] to form an orange viscous solution of cellulose xanthate ([http://cameo.mfa.org/materials/fullrecord.asp?name=viscose 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.

Viscose rayon dress
MFA# 2013.1585
Viscose rayon yarn at 200x
Viscose rayon yarn at 200 x polarized light

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.
