Abstract
Commercial polymer chemicals are provided as auxiliaries for improving the color fastness to crocking of dyed fabrics. Indigo and sulphur dyes, the principal class of dyestuffs used to produce jeans, were used. The dyed fabrics present low dry-wet crocking fastness. Application of polyacrylic and polyourethane polymers to the dyed fabrics by aftertreatment process results in the fastness to crocking improvement of Indigo and CI Sulphur Black 1 dyed cellulosic fabric, whilst retain its other desirable properties. Stiffness, colour changes, and tear resistance measurements of the dyed fabrics were carried. Polyacrylates raised most the stiffness and hardness of the fabrics, compared to aliphatic polyurethanes. Tear resistance of the dyed fabrics was not significantly affected by the auxiliaries’ application. Finally aftertreatment with the above finishing agents affected colour change in different ways.
