Sustainable Cross-Linking of Man-Made Cellulosic Fibers with Poly(carboxylic acids) for Fibrillation Control

Lyocell-type fibers often exhibit a high tendency to fibrillate under wet abrasion conditions, and fibrillation must be diminished for better quality of the textile product. In this study, we propose green route cross-linking regenerated cellulose using citric acid (CA) 1,2,3,4-butanetetracarboxylic (BTCA) prevent from fibrillation. We investigated influence process conditions additives on fiber properties. The cross-linked highly depended concentration cross-linker solution, curing temperature, time. BTCA showed performance in comparison CA. CA also suffer yellowing issues due formation unsaturated side products during curing. Thus, glycerol xylitol were added avoid reaction that led compound. Washing fastness tests confirmed has stability when is 100 g/L are cured at 180 °C 5 min. disadvantage was relatively low mechanical performance. study demonstrated adding softener solution enhanced properties able reduce temperature without deteriorating index fibers.
