100% Viscose Rayon. Extremely clean combed top. Lustrous white, with a staple length of 5 to 6 inches. Viscose is a type of rayon, and considered to be the very first successful manmade fibre after numerous attempts to create artificial silk. It is manufactured from wood pulp. Take advantage of the lovely sheen and soft handle to use this in blends for summer garments. Since this is a plant or cellulose fibre dyers must use fibre reactive dyes. Natural dyers can resort to techniques used on cotton, such as alum-tannin premordanting, or Aluminum acetate. We don't know how viscose responds in an indigo vat. That being said, when blended with protein fibres, acid dyes will leave the viscose alone during dyeing, which makes for some wonderful streaky or heathered effects, depending on how well the fibres are blended.
