丝素蛋白剂对羊毛织物性能的影响 总被引:1,自引:0,他引:1
对羊毛织物进行丝素蛋白剂浸渍-焙烘工艺整理,分别测试整理前后织物的表面性能、防毡缩性能、抗皱性能、透气性能以及风格指标。实验结果表明:羊毛纤维表面附着了一层丝素蛋白膜,羊毛织物的防毡缩性能有很大改善,可以达到机可洗羊毛要求,折皱回复性和透气性能提高了大约10%,织物风格指标也得到了改善,弯曲性能指标显著提高,织物的滑糯感和丰满感也增强了。 相似文献

利用低温等离子技术(LTP技术)对羊毛织物进行表面改性处理,使其具有更优良的服用性能.经LTP技术处理后,毛纤维鳞片被刻蚀,纤维定向摩擦效应和织物收缩率降低,改善了羊毛的毡缩性,若协同柔软剂处理防毡缩效果更佳;羊毛经LTP技术处理后鳞片破坏易于浸润,亲水性和上染率均能显著提高;羊毛纤维经表面改性,出现的纳米尺度的沟槽和凹凸结构利于后整理,经拒水拒油整理后,羊毛织物的拒水性能达到5级,拒油性达到6级. 相似文献

芬顿试剂法对羊毛织物防毡缩及染色性能的影响 总被引:3,自引:1,他引:2
采用芬顿试剂法对羊毛纤维鳞片进行氧化处理,与单用双氧水预处理、蛋白酶处理等常规氧化法进行比较,探讨了芬顿试剂法对羊毛织物防毡缩及染色性能的影响。此外,还讨论了C12H25NaO4S、Fe2+、生物酶及螯合剂EDTA对织物色差ΔE的影响。利用扫描电镜观察被处理羊毛鳞片表层状态,测试了羊毛织物毡缩率、色差、断裂强力。结果表明,芬顿试剂法与常规氧化法相比,对羊毛鳞片具有较强的氧化作用,对羊毛织物防毡缩效果显著,可明显提高织物上染率,织物断裂强力损失率为8.4%,不会影响其服用性能。 相似文献

Fabric woven from wool/polyester (PES) Murata vortex spun (MVS) blend yarn is a commercially viable proposition particularly on the basis of advantageous wear-resistant properties, compared with fabric made from traditional worsted ring-spun yarn. However, in some early industrial trials with fabric made from 45/55-blend wool/PES MVS yarn, significantly greater relaxation shrinkage was found relative to comparable worsted ring-spun fabric. It was noted at the time that the amount of relaxation shrinkage in MVS fabric could be reduced to a large extent by using steamed MVS yarn. In this study, the extent of variations in the dimensional and mechanical properties of fabric samples woven from a combination of steamed and unsteamed MVS yarn and equivalent worsted ring-spun yarn is examined. In general, greater hygral expansion and relaxation shrinkage were found in loom-state fabrics made from unsteamed MVS yarns, whereas the fabric made from steamed MVS and ring-spun yarns gave relatively low levels of relaxation shrinkage and hygral expansion. Permanent setting of fabrics, by pressure steaming, was found to be more effective than yarn pre-steaming in reducing relaxation shrinkage levels of fabrics made from unsteamed MVS yarn. After pressure steaming, all fabrics showed similar levels of relaxation shrinkage and hygral expansion. Permanent setting of the fabrics, by pressure steaming, resulted in similar levels of relaxation shrinkage and hygral expansion, irrespective of the yarn production method; relaxation shrinkage fell to around 1% and hygral expansion increased by about 1%, relative to the loom-state samples. MVS fabrics were relatively heavier and fuller and had a firmer handle than the worsted ring-spun fabrics, reflecting the greater fabric weight, thickness and shear rigidity measured on these fabrics. These attributes are associated with different structures of the worsted ring-spun and MVS yarns used to make the fabrics. 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.
