細丹尼纖維深染助劑配方技術研究
The technology of deep dyeing auxiliary on PET microfiber.
摘要
本研究合成陽離子型深染助劑，藉由染色前處理與染色同時處理之方法，探討染色溫度、助劑組成、助劑添加量、染色時間、升溫速率與助劑分子量等參數，對於細丹尼聚酯纖維之表觀顏色深度(K/S)之影響，並由水洗堅牢度測試與SEM 影像來觀察染色纖維的性質。 首先以3-丙烯醯胺丙基三甲基氯化銨(APTAC)與丙烯腈(AN)為單體，過硫酸銨(APS)為起始劑進行共聚合反應，合成各種組成與分子量之陽離子型深染助劑。 結果顯示，助劑的添加以染色同時處理方式效果較佳，對於K/S 的提昇可高達25％，同時也提高纖維對染色溫度變化的穩定性並且維持良好的水洗堅牢度。不同的助劑組成皆有大幅提昇K/S 的效果，隨著APTAC 的單體含量的增加，可相對減少助劑的使用量，而提高升溫速率與調整適當的助劑分子量則能夠增加纖維染色的K/S 穩定性。

The deep dyeing effect of the disperse dye on polyester microfiber in the presence of cationic auxiliaries synthesized by (3-acrylamidopropyl)trimethyl ammonium chloride (APTAC) and acrylonitrile (AN) as monomers and ammonium persulfate (APS) as the initiator has been developed. The different parameters, dyeing temperature, auxiliary components, auxiliary content, dyeing holding time, dyeing temperature rate and auxiliary’s molecular weight, were discussed. Colour shade depth ( K/S ), wash fastness test and SEM photographs of dyed microfiber were measured. The result showed that the K/S of the dyed microfiber was increased and maintain good wash fastness, with adding cationic auxiliaries (especially with low molecular weight) in the dye bath or decreasing dyeing temperature. The highest value of K/S, 550 (increase 25%), of dyed microfiber was obtained by adding auxiliary.
