采用过氧化氢/醋酸体系降解壳聚糖,得到相对分子质量为3.8×10~5,2×10~5,1.44×10~5,7.2×10~4,3.2×10~4,1.1×10~4,4×10~3的降解壳聚糖,将其分别以不同质量浓度与丁烷四羧酸(BTCA)复配对棉织物进行整理,测试整理后织物的折皱回复角、撕破强力、白度以及对金黄色葡萄球菌的抑菌率,讨论壳聚糖相对分子质量及质量浓度对整理织物抗菌/防皱性能的影响。研究表明:通过一浴一步法,采用相对分子质量为2×105的壳聚糖,以1.0 g/L的质量浓度与BTCA复配整理棉织物,织物的防皱、抗菌性均佳,此时织物的折皱回复角为264.3°,强力保留率为经向77.3%、纬向63.5%,白度为68.3%,抑菌率为68.7%;再加入10.0 g/L的抗菌剂AGP,织物的抑菌率可提高至98.5%,折皱回复角为263.0°,强力保留率经向为83.5%,纬向为76.4%,白度为69.1%。 相似文献

Spun silk and chitosan fiber were blended to fabricate spun silk/chitosan blended yarn with three blending ratios (90/10 and 80/20 and 70/30) by silk spinning technology. The silk/chitosan blended yarn and pure spun silk were used as warp and weft yarn to design and weave 16 fabrics. The 16 mechanical properties about fabric hand feeling were measured at low stress with KES-FB-AUTO fabric style instrument. Six basic style values (stiffness, flatness, suppleness, fullness, smoothness and scroopy) were calculated by Kawabata formula of women's fine dress fabrics. The results reveal that compared with a pure spun silk fabric, spun silk/chitosan blended fabrics have higher stiffness, flatness, smoothness and scroopy, but lower suppleness, and the fullness differs little. © 2017 China Silk Association.

壳聚糖季铵盐在桑蚕丝织物抗菌整理中的应用 总被引:1,自引:0,他引:1
基于壳聚糖季铵盐良好的抑菌性和水溶性,将2,3-环氧丙基三甲基氯化铵与壳聚糖合成了壳聚糖季铵盐。采用最小抑菌浓度法测定和比较了壳聚糖及壳聚糖季铵盐的抗菌性,并将其用于桑蚕丝织物的抗菌整理,采用振荡烧瓶法对处理前后的丝织物进行抗菌性测试。结果表明: 壳聚糖及其季铵盐对金黄色葡萄球菌和大肠杆菌均有显著的抑菌性,且壳聚糖季铵盐的抑菌效果优于壳聚糖;经壳聚糖及其季铵盐处理后,桑蚕丝织物对金黄色葡萄球菌和大肠杆菌的抑菌率均明显提高,且壳聚糖季铵盐的抑菌效果更好。 相似文献

The aim of the current research is to study the improvement of dyeability of silk fabrics using surface modification performed by corona discharge and chitosan pre-treatment. Effects of some operational variables such as corona treatment time, concentration of chitosan, time, and temperature on grafting process were examined through dyeability of silk fabrics using two commercial reactive dyes. Fourier transform infra-red and scanning electron microscopy spectroscopy data revealed the surface modification of the silk by corona discharge and grafting of chitosan onto the silk fabric. Optimal grafting values obtained were corona treatment time 30 min, concentration of chitosan 18% owf, time 2 h and temperature 60 °C. It was found that silk pretreatment with corona discharge and chitosan improved dyeability from 1.84 to 4.58 for RY and from 3.05 to 6.40 for RB. The results indicated that the color fastness and tensile strength of silk fabrics were not significantly affected irrespective of the grafting with corona and chitosan pre-treatment. The results of this study provide the potential making of eco-friendly modification and reactive dyeing of textile fibers using corona discharge and chitosan pre-treatment. 相似文献
