生物酶在天然彩色棉针织物整理上的应用研究

A Study on the Application of Biological Enzyme on Natural Coloured Cotton Knits

天然彩色棉是用杂交和基因改性技术培育出的棉花。尽管天然彩色棉不需染色、印花 ,但为了织造方便 ,纺织厂仍对彩色棉进行浆纱处理 ,并且天然彩色棉同样含有果胶、含氮物、油脂等杂质。为了使彩色棉符合“绿色纺织品”的要求 ,必须采用无害、无污染或少污染的前处理工艺。应用生物酶对彩色棉进行前处理可降低成本、减少污染。文中对酸、碱。

Natural coloured cotton is a kind of cotton cultivated by hybridization and gene modification. Some processess including dyeing and printing are not necessary for coloured cotton. However, in order to make weaving (or knitting) easy and to get rid of the impurities contained in the cotton, such as pectin, nitrogenous matter and grease, sizing process is always taken in spinning mill. A harmless, non pollution or less pollution pretreatment must be adopted for meeting the requirements of 'Green Textiles'. While the pre treating of coloured cotton with biological enzyme is a process with low cost and less pollution. A comprehensive introduction on the influence of acid, alkali, oxidizing agent and biological enzyme on coloured cotton is given.
