全聚赛络纺双芯纱及其弹性电磁屏蔽针织物的制备
|
摘要
为开发弹性回复性更强的防辐射针织物,在全聚纺细纱机上采用嵌入式纺纱方法纺制3种不同线密度的棉/不锈钢/氨纶双芯纱和3种对应线密度的棉/不锈钢包芯纱,设计织制成1+1罗纹组织织物,测试分析纱线的包覆效果和主要性能及织物的弹性回复性、电磁屏蔽等性能。结果表明:6种纱线包覆效果及成纱性能均良好;相比不锈钢包芯纱线织物,双芯纱织物在弹性回复和屏蔽电磁波方面有很大的优势,达到一般性民用电磁屏蔽织物的要求且能保证人体舒适性,这种新结构纱线在全聚纺设备上生产是可行的;开发弹性电磁屏蔽织物时,不仅要合理选择长丝预牵伸倍数等工艺参数,还要考虑到织物的服用性、耐久性及生产成本。
In this paper,a kind of radiation resistant knitted fabric with higher elastic response ratio was developed. Three kinds of cotton/stainless steel/spandex double filament core-spun yarns and three kinds of cotton/stainless steel core-spun yarns with different linear density were spun by using complete condensed Siro-spinning. In the spinning,the double filament core-spun yarns were spun by feeding the stainless steel and spandex filament into the front roller of spinning machine,and corresponding 1 + 1 rib loop weaves was knitted. Then,the covering effect and the qualities of six simple yarns,and the elastic recovery ratio,electromagnetic shielding properties and fabric styles of six sample fabrics were tested and compared. The test results indicated that all the yarns have good covering effect and good yarn performance. Compared to stainless steel core-spun fabric, the double-core fabric have a better advantages in elastic recovery ratio and shielding electromagnetic waves to meet the requirements of general civil electromagnetic shielding fabric and to guarantee human comfort. The development of flexible electromagnetic shielding fabric not only focus on selection of a reasonable filament pre-draft multiple and other processes,but also take the usability,durability and production costs of the fabric into account.
