Unsaturated fatty acids based materials as auxiliaries for printing and finishing of cellulosic fabrics

Abstract

Surface-active agents were used in textile industries in all processes. Fatty acid derivatives based materials known as important auxiliaries. This research aims to develop some unsaturated fatty acids derivatives to be used as textile auxiliaries. Three unsaturated fatty acids were reacted with materials having different structure (PEG; 1000, 4000 and 6000 g/mole), polyethylenimine (PEI), stearyl alcohol and Octadecylamine). Synthesized auxiliaries were characterised by measuring FT-IR, HLB and cloud point and stability over different time period. Produced materials after characterisation were classified to be used as O/W emulsifiers or softeners. Applied these materials as softeners on cotton fabrics provide good physical and mechanical properties. Furthermore, using these materials as emulsifiers to prepare printing pastes and apply them into cotton fabrics provide good colour strength and colour fastness of printed fabrics.
