Abstract
The purified tencel fabrics were treated with NaOH, liquid ammonia (NH$_3$), NaOH and subsequently NH$_3$, and also market product tencel (MPT) treated arith NH$_3$. Finally the pretreated tencel fabrics were processed with enzyme (cellulase). The crystalline structure, SEM, moisture regain, water absorbency, tensile strength, and dyeing behavior of the specimens were studied. The degree of crystallinities decreased in the order of MPT-NH$_3$ > NaOH/MH$_3$ ) MH$_3$ > NaOH > MPT > untreated tencel. However moisture regain and water absorbency of the NH$_3$-treated tencel were lower than those of the untreated because of swelling characteristic of MH$_3$. The NH$_3$ treated-tencel fabric increased in the dry strength compared to untreated tencel. The increase in rate of dyeing was in the order of NaOH > NaOH > NH$_3$ > MPT-NH$_3$ > MPT > untreated tencel fabrics. The equilibrium exhaustion appeared In the order of NaOH > NaOH/NH$_3$ > MPT-NH$_3$ > untreated > MPT The fiber surface of the NH$_3$-pretreated tencel fabrics was remarkably fibrillated by cellulase treatment. The weight loss by cellulase treatment increased in the order of NaOH/NH$_3$> NH > NaOH-treated tencel fabrics and equilibrium exhaustion decreased by cellulase treatment.
