摘要
研究原料种类和纺织工艺对PTT/毛织物弹性的影响,结果表明:试制产品的弹性从优到劣的次序为毛与PTT/PET长丝sirofil复合纺织物>毛与PTT长丝sirofil复合纺织物>经短纤纱与纬PTT长丝交织织物>PTT/毛混纺织物;改变煮呢工艺,提高煮呢温度,热定型中加强超喂都有利于提高织物弹性。采用多元线性回归方法分析PTT/毛混纺织物结构参数与弹性伸长的关系,认为织物的经向上机紧度对织物弹性伸长的影响最大,其次为组织浮长和纬向上机紧度。
The influence of raw materials and weaving processing on the elasticity of PTT/wool fabric was investigated through experiments. The order of elasticity of different materials is as follows： wool and PTT/PET filament sirofil 〉 wool/PTT filament sirofil fabric 〉 the fabric interwoven with wool/PTT and PTT filament 〉 PTT/wool blended fabric;varying boiling process, raising the boiling temperature, and increasing overfeed in heat setting all facilitate the elasticity improvement of the fabric. The relation equation between the structure parameters and the elastic elongation of PTT/wool blended fabric was established using multivariate linear regression method. The result shows that the loom warp tightness is the most important factor on elastic elongation, and followed by float, and finally, loom weft tightness.
