| 摘要: | 本研究主要係以不同強鹼劑(NaOH、KOH及LiOH)對新纖維素材Tencel織物進行絲光 加工，並於定張力下改變鹼液濃度、加工溫度及時間，探討Tencel織物之絲光效果及染著性 。由實驗結果得知：鹼液濃度愈高，絲光效果及染著性愈好；但處理時間及溫度對其絲光效 果、染著性並無明顯的影響，而三種鹼液之絲光效果其順序為KOH>NaOH>LiOH，染著性之順 序為KOH>NaOH>LiOH。
Mercerization of Tencel fabrics using different alkali hydroxides (such as NaOH, KOH and LiOH) under constant tension had been studied. The influences of concentration 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 fabrics had the tendency to increase with the concentration of alkali solutions increased. In addition, the treating temperature and duration had no significant effect on the experimental results. The effectiveness of alkali hydroxides for BAN value is in the order as follows: KOH>NaOH>LiOH, and the colourabilities (K/S values) in the order, KOH>NaOH>LiOH. |
