壳聚糖对棉针织物活性染料染色效果的影响 总被引:2,自引:0,他引:2
探讨了壳聚糖预处理后再染色、壳聚糖与染料同浴以及染色后再壳聚糖处理3种工艺方法对纯棉针织物染色效果的影响。分析了壳聚糖分子量、脱乙酰度、浓度等因素对经壳聚糖预处理后再用活性染料染色的棉针织物的染色性能的影响。在此单因素实验的基础上.通过正交实验确定了壳聚糖预处理后再染色的最佳工艺.并按照最佳工艺条件分析了壳聚糖对不同活性染料染色效果的影响。实验结果表明:采用壳聚糖预处理织物再染色,可以提高织物的色深值.但摩擦牢度和耐洗牢度略有下降;将壳聚糖与染料同浴使用,会使织物的色深值、摩擦牢度和耐洗牢度均下降:染色后再用壳聚糖处理的织物色深值有所下降.但摩擦牢度和耐洗牢度可提高0.5~1级:分子量小、脱乙酰度高的壳聚糖对织物染色的增深效果明显、且织物的K/S值随着壳聚糖溶液浓度的增加而先逐渐增加后减小:织物先壳聚糖预处理再染色的最佳工艺为壳聚糖浓度0.2%.盐浓度20g/L,轧余率100%。 相似文献

The simultaneous in situ synthesis of silver nanoparticles and slenderizing of wool fibers was carried out in one single step process without using external reducing agent. The functional groups of wool fibers were responsible for the reduction of silver ions into silver nanoparticles, and the possible interactions between the synthesized nanoparticles and the protein chains of wool fibers have been thoroughly discussed. According to the hypothesized mechanism, which was further proved by UV–vis absorption spectra, there is also a possibility of cross-linking formation within wool protein chains through diazotion reaction with amine groups of wool fibers. Duration of the process at the applied temperature allowed enough time for complete growth of the silver nucleus inside the protein chains, creating more cross-linking within the protein chains of wool fibers. Findings suggest the potential of the proposed method in producing fine wool fibers with enhanced tensile strength and slight color change. 相似文献

A facile route for the synthesis of high-quality Fe3O4 nanoparticles (FNPs) has been successfully confirmed by employing a co-precipitation technique and then was stabilized onto wool fabric through a simple “impregnating” process. Here, the synergistic effect of BTCA and synthesized FNPs on magnetic and antifungal characteristics of the wool fabric was investigated. The FNPs was stabilized on the wool surface using BTCA cross-linking agent. The role of both FNPs and BTCA concentrations on magnetic and antifungal properties of samples was optimized using response surface methodology. The magnetization properties and uniform distribution of FNPs on the wool surface were characterized by vibrating sample magnetometry, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. The saturation magnetization and antifungal activity against Candida albicans of BTCA/FNPs-optimized wool was 7.8 emu g?1 and 98.31%, respectively. Subsequently, treated wool fabric with optimum concentration of FNPs and BTCA enhanced magnetic and antifungal properties. 相似文献
