轻量保暖吸湿发热内衣面料开发

采用膨体腈纶黏胶混纺纱、锦纶氨纶包芯丝、棉黏胶混纺纱和锦纶长丝4种纱线在20G罗纹机上交织开发了变化罗纹组织针织面料。通过设定适当的编织线长，里层膨体腈纶黏胶混纱线进行针布起毛整理，染缸中和热定型柔软加工，得到210g/m2轻量保暖吸湿发热针织内衣面料。保温率达到30%以上，吸湿发热值达到2.8℃以上，且手感柔软、横向拉伸性好、穿着舒适，可用于冬季保暖内衣产品。

Development of Moisture-absorption and Heat-generating Light Weight Thermal Underwear Fabric

The bulked acrylic and rayon blended yarn,nylon and spandex covering yarn,cotton and rayon yarn and nylon filament were used to develop knitted fabrics with variable rib weave on 20 G gauge rib machine.Through the appropriate loop length setting,needle cloth raising process on bulked acrylic and rayon blended yarn,dyeing vat neutralization,heat setting and soft process,210 g/m² light weight thermal knitted fabric was got.The heat preservation rate was more than 30%,and moisture-absorption and heat-generating value was more than 2.8℃.The fabric had soft hand feel,good lateral elongation and comfort,which could be used in winter thermal underwear product.
