摘要
为解决酸性纤维素酶水洗整理中的靛蓝返沾现象,研究了阴离子(SDS)、两性离子(PC)和非离子表面活性剂(T60和AEO-9)对纤维素酶吸附和水解性能的影响,同时测试了表面活性剂复配对牛仔织物水洗性能的影响。结果显示:在靛蓝对纤维素酶的吸附性能上,3种表面活性剂影响程度较弱;在微晶纤维素对酶的吸附上,阴离子和非离子表面活性剂有较好的抑制作用;在水解性能上,阴离子表面活性剂易造成酶失活,而非离子表面活性剂以及两性离子影响较小,甚至还有一定激活作用;CIE L和CIE|b|值测试表明,阴离子与非离子表面活性剂复配对纤维素酶水洗性能的提升较差,而非离子与非离子表面活性剂复配后则可以达到较好的水洗效果。
In order to solve the problem of indigo back staining in cellulase bio-washing, the influences of anionic surfactant （SDS）, zwitterionic surfactant （PC） and nonionic surfactants （T60 and AEO-9 ） on cellulase adsorption and hydrolysis were investigated, as well as the impact of complex system of different surfactants on denim bio-washing. The results showed that the selected surfactants had slight effect on indigo adsorption with cellulase. However, anionic surfactant and nonionic surfactant could decrease the adsorption amount of cellulase onto micro-crystalline cellulose. For the cellulase hydrolysis, anionic surfactant greatly reduced the cellulase activity, while zwitterionic surfactant and nonionic surfactants had little effect on it, or even had certain activation. Finally, the CIE L and CIE ｜b｜ values showed that the synergism of anionic surfactant and nonionic surfactant didn＇t reach a good bio-washing result while the synergism of non-ionic surfactants had a better performance.
