『紮染』是一種使織物在染色時部分結紮起來使之不能著色的一種染色方法，是中國傳統的手工染色工藝之一，有著悠久的歷史，流傳至今，不僅是傳統文化亦為一種時尚元素。本文利用紮染的概念結合現代的染色製程及染料特性等技術，應用液流染色機，嘗試以人造纖維來模擬紮染量化生產的可能性，期望能夠在本文所使用的尼龍針織布上產生類似紮染效果的多樣性變化外觀。
本研究設定多個不同的染色條件；條件分為3組，觀察在各條件下的外觀變化及差異性。
第一組：常溫加入染料及助劑及加藥順序不同
1.1先加入染料及硫酸銨後加入冰醋酸
1.2先加入冰醋酸後加入染料及硫酸銨
第二組：在不同溫度下加入染料
2.1在70℃加入染料
2.2在98℃加入染料
第三組：在特定溫度下持溫
3.1在70℃持溫30分鐘
3.2直接升溫至98℃持溫30分鐘|
Tie-dye is one of the traditional ways of dyeing in China. When the greige fabrics proceed tie-dye, part of the fabric are tied or knotted to remain un-dyed at some area throughout the dyeing process. To this day, tie-dye has become a traditional culture added with elements of modern fashion. It has a long history and reserved until now. As the market demands grow, pattern design for tie-dye becomes more and more complicated and diversified. Its application is no longer limited to apparel. Some of them are widely used on upholstery, such as use on curtains or covers for sofa or bed.
Combined tie-dye concept with modern dyeing process and characteristics of dyestuff, this study uses existing liquid-flow dyeing machine for dyeing Nylon fabrics. Not only is it aimed at creating plentifully varied appearances similar to tie-dye for Nylon knitted fabrics. Also, it is trying to explore the possibility of simulating duplicating tie-dye products massively for knitted fabrics made of synthetic fibers.
In order to observe the appearance change and find the difference between different tested conditions, there are three groups experiment of the dyeing process in this study.
I.Dyeing conditions: Dyestuff and auxiliary are added under
II.Add the dyestuffs at different temperatures,
III.Dyeing is proceeded with or without keeping temperature at 70℃.
