改性黏胶/棉纬编面料开发

采用改性黏胶纤维ComfortechTM与长绒棉纤维按质量比40/60混合,经赛络紧密纺工艺纺制成19.44 tex改性黏胶/棉混纺纱,测试并分析该混纺纱的捻度、毛羽、摩擦因数、条干不匀和力学性能等指标;再经组织结构设计、针织和染整加工,开发含成圈、集圈、浮线等花色组织的改性黏胶/棉纬编面料,测试与分析该面料的扭曲性、刚柔性、抗起毛起球性、透气性、缩水性、染色牢度、pH值、甲醛含量、偶氮含量和抗菌性等指标。结果显示改性黏胶/棉纬编面料不仅具有手感柔软、透气性好等优良的服用性能,且染色牢度高,抗菌功能良好。

Development of modified viscose/cotton weft knitted fabrics

The modified viscose fiber ComfortechTM was mixed with long-staple cotton fiber according to the mass ratio of 40/60 to prepare 19.44 tex modified viscose/cotton blended yarn by Siro-compact spinning process.The indexes including twist,hairiness,frictional factor,unevenness and mechanical properties of the blended yarn were tested and analyzed.Then,the modified viscose/cotton weft knitted fabrics containing such fancy stitches as loop,tuck and floating thread were prepared through structutre design,knitting,dyeing and finishing processes.The indexes including tortuosity,stiffness,anti-pilling and fuzzing,air permeability,washing shrinkage,color fastness,pH value,formaldehyde content,azo content and anti-bacterial properties of the fabics were tested and analyzed.The results showed that the modified viscose/cotton weft knitted fabric not only had excellent wearability such as softness handle and good air permeability,but also its color fastness was high and anti-bacterial function was good.
