Improving the development of high-value multifunctional wool fabrics was essential to satisfy diverse needs. Considering the various characteristics of chitosan macromolecules, herein, a padding-cross-linking process was adopted and then multifunctional wool fabrics with outstanding printing effects, shrink resistance, and antibacterial properties were fabricated. The test results showed that chitosan macromolecules loaded successfully on the wool fiber surface by Schiff base reaction. Wool fabrics changed from hydrophobic to hydrophilic due to the existence of chitosan macromolecules. The color strength (K/S value) of the reactive dye inkjet-printed wool fabric was greatly increased from 20.48 to 26.6. The area shrinkage of final samples was 2.53%, which was exceedingly lower than that of the original wool (10.96%). Moreover, the chitosan macromolecules with reactive amino groups endowed wool fabrics with certain antibacterial properties against E. coli and S. aureus. Generally, this study provided guidance for manufacturing multifunctional digital inkjet-printed wool products in mass production.

席夫碱反应制备用于活性染料数码喷墨印花的壳聚糖多功能毛织物

提高高附加值多功能毛织物的开发水平，对于满足多样化需求至关重要。考虑到壳聚糖大分子的各种特性，本文采用浸轧交联工艺，制备出具有优异印花效果、抗缩水和抗菌性能的多功能毛织物。试验结果表明，壳聚糖大分子通过席夫碱反应成功负载在羊毛纤维表面。由于壳聚糖大分子的存在，羊毛织物由疏水变为亲水。颜色强度（K / S活性染料喷墨印花羊毛织物的值）从 20.48 大幅提高到 26.6。最终样品的面积收缩率为2.53%，远低于原毛的10.96%。此外，具有活性氨基的壳聚糖大分子赋予了羊毛织物对大肠杆菌和金黄色葡萄球菌的一定抗菌性能。总的来说，这项研究为大规模生产多功能数码喷墨印花羊毛产品提供了指导。
