摘要/Abstract

摘要： 利用非离子表面活性剂NP-10与纤维素酶协同制备了稳定的有机颜料水性分散体系，并研究其对阳离子改性棉织物的染色性能。首先，利用紫外吸收光谱验证了NP-10与纤维素酶在溶液中通过疏水作用发生缔合；其次，通过稳定性测试表明纤维素酶能够提高颜料分散体的稳定性，通过粒度测试发现纤维素酶有助于减小颜料粒径，通过电位测试发现纤维素酶的加入可增加颜料颗粒的Zeta电位；最后，通过颜色深度测试，表明纤维素酶的加入有助于织物染色深度的提高，在pH为4的条件下可获得最大染色深度。

Abstract: In this study, nonionic surfactant NP-10 and cellulase were used to prepare a stable organic pigment waterborne dispersion system, whose dyeability on cationically modified cotton fabrics was studied. The UV absorption spectrum revealed that NP-10 and cellulase were associated in solution by hydrophobic interaction. The stability test showed that cellulase could improve the stability of pigment dispersion. The particle size test showed that cellulase helped to reduce the particle size of pigment. The potential test indicated that the addition of cellulase could increase the zeta potential of pigment particles. The color depth test showed that the addition of cellulase could help to improve the dyeing depth, and the maximum dyeing depth could be obtained under the condition of pH 4.

Key words: cellulase, organic pigment, dispersion system, cotton fabric, dyeing
