腈纶基吸湿发热单面绒面料的设计与生产

为研究吸湿发热保暖纤维的保暖机制及性能特点,开发保暖面料。以线密度为28 tex的棉纱为经纱,以单纱线密度为15.5 tex 2合股的腈纶/铜氨纤维(60/40)发热混纺纱为纬纱,设计开发腈纶基吸湿发热单面绒面料。优化各道工序:络筒速度575 m/min、络筒张力垫圈质量13 g、整经速度690 m/min、浆纱速度52 m/min、上浆率为9%,织机速度196 r/min、开口时间295°、后梁高度100 mm,车间温湿度偏大控制、车间温度范围24~30℃、相对湿度70%~75%。结果表明:选用吸湿发热纤维是提升面料保暖效果的主要措施,选用粗支纱线、起绒面料、紧密织物组织等,可以进一步提升面料保暖效果。

Design and production of acrylic-based moisture absorption & heat generating fabric with single raising face

In order to further improve the thermal protection function of the fabric,the heating mechanism and performance characteristics of moisture absorption&heat generating fibers were studied.The cotton yarn of 28 tex was used as warp yarn and the acrylic/cuprammonia(60/40)moisture absorption&heat generating yarn of 15.5 tex×2 was used as weft yarn.The optimized process parameters were:winding speed was 575 m/min,winding tension was 13 g,warping speed was 690 m/min,sizing speed was 52 m/min,sizing percentage was 9%,weaving speed was 196 r/min,open-time was 295°,rear beam height was 100 mm,temperature and humidity should be controlled strictly,temperature was 24~30℃,humidity was controlled between 70%and 75%.The results showed that the heat protection function of the fabrics could be further improved by using thick yarns,fleece fabrics and tight fabric.
