探讨了丝素/纳米银溶胶对粘胶织物整理的最佳工艺,以及在该工艺条件下粘胶织物的抗菌性、服用性与染色性能。研究表明,纳米银离子溶胶整理粘胶织物的最佳工艺条件为丝素/纳米银溶胶质量浓度100 mg/L、浸渍温度80℃、浸渍时间15 min。整理后粘胶织物对大肠埃希菌与金黄葡萄球菌的抑菌率均达到85%以上,且织物的抗静电性能、吸湿回潮率、折皱回复角、力学性能及染色性能都有不同程度的提高,验证了丝素/纳米银溶胶整理对粘胶织物功能整理的可行性。 相似文献

芳砜纶产品在生产和使用过程中极易产生静电,限制了芳砜纶在多种场合的应用。研究证明,使用阴离子型表面活性剂作为抗静电剂,可以消除芳砜纶在纺纱过程中的静电;采用吸湿性能好的纤维与芳砜纶混纺或在针织机上混织,当混合比适当时,既可以保持芳砜纶良好的阻燃性能,又可以改善芳砜纶织物的抗静电性能。10%羊毛、20%阻燃粘胶及碳纤维等纤维原料,与芳砜纶进行混纺或混织,其织物的阻燃性能达到国家阻燃产品的标准要求,抗静电性能也可以得到最为显著的改善。 相似文献

大麻与棉及其混纺纱线吸放湿性能研究 总被引:1,自引:0,他引:1
纱线的吸湿透湿性能是影响纺织品舒适性的基本条件和重要因素。测试大麻、棉、棉/大麻和棉/大麻/莫代尔这4种纱线在不同温湿度条件下的吸放湿性能。结果表明:大麻纱线的毛效数值最高,可达11.0cm,说明大麻纱线具有很好的吸湿性能;同一温湿度条件下,当纱线吸湿达到平衡时,大麻、棉和棉/大麻混纺纱线的回潮率接近,棉/大麻/莫代尔混纺纱线的回潮率明显比前3种纱线高;棉/大麻/莫代尔混纺纱线的吸湿放湿速率最大,吸湿放湿速率减小的最快;大麻纱线的吸湿放湿速率比棉、棉/大麻混纺纱线快。 相似文献

为改善麻纤维因自身性能缺陷与传统纺织工艺局限性所导致的成纱毛羽问题,将旋流喷嘴纺纱技术应用于精细化亚麻/长绒棉/天丝和大麻/棉/粘胶2种混纺纱的纺制,选择适当的细纱工艺参数并测试成纱后的主要性能指标。结果表明:当旋流喷嘴中通入的气流压强为0.1 MPa时,亚麻混纺纱的有害毛羽数量相对于传统环锭细纱降低了89.9%,压强为0.05 MPa时,大麻混纺纱的有害毛羽数量降低了99%;显微镜下2种混纺纱线的纱体结构紧密,纤维排列整齐,纱线表面光洁,大麻混纺纱中的黑色粘胶长丝均匀包裹在纱体表面,使得纱线色泽更为均匀;纱线断裂强力与条干不匀率稍有降低,但变化不明显。 相似文献

Novel engineering approach to optimization of thermal comfort properties of hemp containing textiles
Snežana B. Stanković Milada Novaković Dušan M. Popović Goran B. Poparić Matejka Bizjak 《纺织学会志》2013,104(9):1271-1279
The aim of this research was to investigate the possibilities of producing comfort hemp containing textile fabrics by assembling a pure hemp yarn with other-fibre containing yarn. The plain knitted fabrics were produced from two-assembled hemp and three variants of cotton yarns which differed in twist level, all having the same linear density. The transport properties (air permeability, water vapour permeability and thermal resistance) of the hemp-based knitted fabrics were quantitatively analysed. The results obtained demonstrated that the introduction of cotton into hemp-based textiles reduces air and water vapour permeability with the downward trend in thermal resistance. The extent to which the transport properties varied among the hemp/cotton knitted fabrics was dependent on the twist intensity of the cotton yarns. Therefore, the yarn assembling technique is an effective way not only to combine different fibre properties but to take advantage of intrinsic properties of component yarns. 相似文献

UHMWPE fiber has high specific strength and specific modulus, hut poor moisture absorption.In the paper, with viscose staple fiber as the outer fiber, and UHMWFE staple fiber yarn( 14.75 tex) and filament( 16.67 tex) as the core yarn, 34 tex core-spun yarn was spun.With viscose staple fiber as the intermediate fiber, and UHMWPE staple fiber yarn ( 14.75 tex) and filainent( 16.67 tex) as wrapping fiber, 34 tex Sirofil yarn was spun.The performance of Sirofil yarn was optimized by changing the spacing between the UHMWPE staple fiber yarn or filament and the fiber strand.The results showed that for yams with the same linear density, except for elongation at break, core-spun yams and Sirofil yams with UHMWFE filament as the core yam or wrapping fiber were better than core-spun yams and Sirofil yarns with UHMWFE staple fiber yarn as the (tore yarn or wrapping fiber in strength, evenness and hairiness.When Sirofil yams are spun, the spacing between the UHMWPE staple fiber yarn and fiber strand is preferably 8 mm, and the spacing between the UHMWPE filament and fiber strand is preferably 6 mm. © 2021 China Silk Association.

为更好地探究柔洁纺技术对粘胶强捻纱质量和其机织物服用性能的影响,对相同工艺参数下粘胶强捻柔洁纺纱线与环锭纺纱线的均匀度、毛羽、单纱强力、捻缩率和表观结构进行测试对比,同时分析了相同规格柔洁纺和环锭纺粘胶强捻纱织物的强伸性、顶破性能、撕破性能、透气透湿性、吸湿性、柔软性和抗起毛起球性能。结果表明:柔洁纺粘胶强捻纱的毛羽少,条干均匀,强力高,捻缩率低;相比环锭纺粘胶强捻纱织物,柔洁纺粘胶强捻纱机织物的强伸性、顶破性能、撕破性能、透气透湿性、柔软性和抗起毛起球性显著提高,但吸湿性有所降低;柔洁纺粘胶强捻纱具有柔顺、整洁、牢固等特点,其机织物的综合服用性能优于环锭纺。 相似文献
