摘要

本研究主要係對新纖維素材Tencel紗以不同強鹼劑於改變張力下進行絲光加工，探討Tencel紗之絲光效果及物性變化。本研究採用LiOH、NaOH及KOH此三種鹼劑並改變張力、鹼劑濃渡、加工時間及溫度等條件針對Tencel紗之絲光效果、染著效果、強力、收縮率及膨潤現象進行研究。由實驗結果顯示：當鹼劑濃度愈高，染色性及絲光效果效果愈好。溫度低時，絲光效果及染色效果較好。張力愈小，絲光效果及染色效果較好。三種鹼劑中，絲光效果以KOH較好。

Mercerization of Tencel yarns using different alkali hydroxides (such as LiOH , Na OH and KOH) under different tension had been studied. The influences of concentration of alkali agents, treating temperature and duration on mercerization of alkali agents, treating temperature and duration on mercerization were investigated. The barium activity number (abbr. BAN values) and colour ability (K/S values) of Tencel yarns had the tendency to increase with the concentration of alkali solutions increased. In addition, Inducing yarns shrinkage in width and length which is not the tension applied. The barium activity and colour ability of Tencel yarns had tendency to increase with the treating temperature and tension decrease. The best effectiveness of alkali hydroxides for BAN value is KOH.
