1、摘要?dú)ぞ厶牵藁旒忈樋椢锸且环N具有抗菌性的功能性面料,廣泛應(yīng)用于內(nèi)衣、襪子等產(chǎn)品,具有廣泛的應(yīng)用前景。盡管殼聚糖纖維具有優(yōu)良的抗菌性,但在煮漂及染色過(guò)程中造成抗菌性能的降低。本文比較不同混紡比殼聚糖/棉混紡針織物的抗菌性,當(dāng)殼聚糖/棉混紡針織物中殼聚糖脫乙酰度達(dá)到80%以上,殼聚糖含量達(dá)到5%以上時(shí),具有抗菌性,并且隨著殼聚糖含量的增加混紡針織物的抗菌性提高。課題的研究從實(shí)際生產(chǎn)出發(fā),對(duì)不同煮漂工藝及染色工藝進(jìn)行比較得出:(1)改進(jìn)后的煮漂工藝采用溫和的中性生物精練酶精練一改進(jìn)的氧漂法,避免使用酸,不僅對(duì)殼聚糖纖維損傷小,而且對(duì)混紡織物的抗菌性影響小,并且大大減少環(huán)境污染。(2)殼
2、聚糖/棉混紡針織物采用活性染料,低溫緩染進(jìn)行染色,不僅可以提高勻染性,還可降低殼聚糖質(zhì)量損失,具有較好的織物染色牢度、頂破強(qiáng)力、抗菌性等。本文探討了煮漂方法、染色方法(恒溫法、升溫法和冷軋堆法)、染色工藝條件(溫度,pH值等因素)、染色助劑、染料(活性染料和直接染料)與表面活性劑對(duì)殼聚糖/棉混紡針織物抗菌性的影響,最終得出的工藝參數(shù)用于提供基礎(chǔ)數(shù)據(jù)進(jìn)而指導(dǎo)實(shí)際生產(chǎn)。關(guān)鍵詞:殼聚糖混紡;抗菌性;煮漂,染色AbstractChitosan/cottonblendedknittedfabriciSakindofantibacterialfunctionalfabric.iSwidelyu
