牛奶蛋白纤维不锈钢长丝包芯纱的研制

分析用于纺织品中的不锈钢长丝的表面形态及力学性能。介绍了不锈钢丝牛奶蛋白纤维包芯纱的纺纱装置、工艺流程及原理。并对5种不同特数、不同不锈钢丝含量包芯纱力学性能、纵向形态及毛羽指数等进行对比分析。结果表明:将不锈钢长丝与牛奶蛋白纤维做成包芯纱用于设计电磁屏蔽面料是可行的。既有牛奶蛋白纤维的舒适性,又具有防电磁辐射的功能。与纯牛奶蛋白纤维纱比较,其断裂强度随不锈钢丝含量增大而减小;断裂伸长在不锈钢丝含量30%以内时,降低不明显,30%以上时明显减小。成纱2 mm、3 mm毛羽数高于纯牛奶蛋白纤维纱。

Development of Milk Protein Fibre Stainless Steel Filament Core-spun Yarn

Surface morphology and mechanical properties of stainless steel filament used in textile products were analysed.Spinning device,technology process and principle of milk protein fibre stainless steel filament core-spun yarn were introduced.Mechanical properties,lonnitudinal morphology and hairiness indexes of five kinds of milk protein fibre stainless steel filament core-spun yarn with different count and different stainless steel filament content were contrasted and analysed.The result shows that it is feasible that using milk protein fibre stainless steel filament into core-spun yarn design the electromagnetic shielding fabric.The fabric not only have comfortableness of milk protein fibre but also have the function of anti-electromagnetic radiation.Comparing with pure milk protein fibre yarn,the breaking tenacity of the yarn is increasing when the content of stainless steel filament is reducing.When stainless steel filament content is less than 30%,decrease of breaking elongation is not obvious,but when the content is more than 30% the decrease is obvious.2 mm and 3 mm hairiness indexes of the yarn are more than that of pure milk protein fibre yarn.
