Influence of Anti-Crease Finish on the Shade of Textiles

Abstract

The influence of anticrease agents on the shade was investigated. These agents increase the washfastness, but their effect on the light fastness is different. Their influence is favourable if atomic groups, which are electron donors, are built into them (for instance OH-groups). Anticrease agents also exert influence on the change of the shade. Particularly remarkable effect is that of DMEU and melamine resin. The influence of DMDHEU on the shade is meaingless and for this reason the most favourable for application. The possibility of simultaneous deying of cotton with acid dyestuffs and finishing with basic resins are the subjects discussed. Also fabrics, if crease-proof pretreated, can be dyed. The possibility of simultaneous deying (with Indigosols) and crease resist finishing on polyester/cotton mixed fabrics is pointed out. The investigation of the process of finishing and dyeing on polyester/cotton mixed fabrics with disperse dyestuffs in liquid ammonia is described.
