Abstract

The objectives of this research work were to investigate the effect of air pressure on properties of polyester/nylon intermingled yarn and melange fabric with special reference to melange fabric appearance. Air pressure has significant negative correlation with all the intermingled yarn properties except mingle stability. Air pressure has positive correlations with melange fabric appearance in terms of black pixels and negative correlation with fabric weight. Regression analysis show that the effects with intermingled yarn properties and melange fabric properties are statistically significant except the number of mingle points. Melange appearance varies from stripe to homogeneous distribution when the air pressure is increased. Air pressure does not have significant influence on the number of mingle points. Mingle stability results indicate that 2 bar air pressure is not adequate for intermingling and the pressure between 3 bar and 4 bar seems more economical to operate that gives higher mingle stability. Higher yarn linear density at 3 bar and 4 bar air pressures indicate higher level of entanglements. Melange fabric weight decreases when air pressure is increased, but the weight difference between 3 bar 4 bar is not significant. Therefore, it can be concluded that air pressure is a critical parameter in developing melange fabrics from polyester/nylon intermingled yarns and the air pressure from 3 bar to 4 bar seems more economical and gives better intermingled yarn and fabric permeance.

摘要

这项研究工作的目的是研究空气压力对聚酯/尼龙混纺纱和混杂织物性能的影响，特别要注意混杂织物的外观。除混合稳定性外，气压与所有混杂的纱线性能均具有显着的负相关性。空气压力与混杂织物外观呈黑色像素正相关，与织物重量呈负相关。回归分析表明，除了混合点的数量外，具有混合的纱线特性和混杂织物特性的影响在统计学上是显着的。当气压增加时，混合物的外观从条纹到均匀分布不等。气压对混合点的数量没有显着影响。混合稳定性结果表明2 bar的气压不足以进行混合，并且3 bar和4 bar之间的压力似乎更经济实惠，可以实现更高的混合稳定性。在3 bar和4 bar气压下较高的纱线线密度表明缠结程度更高。当气压增加时，混合面料的重量会减少，但是3 bar和4 bar之间的重量差并不明显。因此，可以得出结论，空气压力是由聚酯/尼龙混纺纱线开发混杂织物的关键参数，从3 bar到4 bar的气压似乎更经济，并具有更好的纱线混纺和织物渗透性。在3 bar和4 bar气压下较高的纱线线密度表明缠结程度更高。当气压增加时，混合面料的重量会减少，但是3 bar和4 bar之间的重量差并不明显。因此，可以得出结论，空气压力是由聚酯/尼龙混纺纱线开发混杂织物的关键参数，从3 bar到4 bar的气压似乎更经济，并具有更好的纱线混纺和织物渗透性。在3 bar和4 bar气压下较高的纱线线密度表明缠结程度更高。当气压增加时，混合面料的重量会减少，但是3 bar和4 bar之间的重量差并不明显。因此，可以得出结论，空气压力是由聚酯/尼龙混纺纱线开发混杂织物的关键参数，从3 bar到4 bar的气压似乎更经济，并具有更好的纱线混纺和织物渗透性。
