ABSTRACT
The present study was carried out with blended fabrics developed from 25:75, 50:50, 75:25 Calotropis/cotton-blended yarns. The cloth count of warp way was significantly different in all the four blends but it was highest in weft way. Shrinkage was higher in calotropis blends than in cotton warp way. Weft-way shrinkage was much lower and less varied between blend cotton fabric had a high degree of crease recovery angle in warp and weft direction. It was observed that the crease recovery angle was less in the weft way in all the four fabric. Calotropis-blended fabric has a less crease recovery angle than the 100% cotton fabric which has increased after dyeing and finishing both warp and weft way. The addition of Calotropis fiber appeared to increase the bending length indicating that the Calotropis fiber was stiffer than cotton fiber which has decreased after dyeing and finishing both warp and weft way.GSM (Grams per square meter) weight, air permeability was highest in 25:75 blended fabric compare to other blended fabrics which have been improved after dyeing and finishing. 75:25 Calotropis/cotton fabrics have a high tensile strength and the Extension of blended fabric are higher in the 50:50 blend compared to other fabric warp way.
摘要
采用25:75、50:50、75:25钙/棉混纺纱混纺织物进行了研究. 四种混纺织物经向织物数差异显著，纬向织物的经纱条数最高. 钙质混纺织物的收缩率高于棉经纱. 纬向收缩率较低，混纺棉织物的经纬向折皱回复角较高. 结果表明，四种织物纬向折皱回复角均较小. 纯棉混纺织物的折皱回复角小于经、纬两种染整后增加的100%纯棉织物.在经纬两种染整方式下，纤维的加入使弯曲长度增加，说明纤维的硬度比棉纤维高. 25:75混纺织物的透气性最高，与其他经染整后有所改善的混纺织物相比，透气性最高. 与其他经纱方式相比，75:25钙/棉混纺织物具有较高的拉伸强度，50:50混纺织物的延伸率较高.
