织物紧度和抗皱整理工艺对纯棉机织物折皱回复性的影响

为提升棉织物的抗皱性能,研究了织物紧度和抗皱整理工艺的协同作用对棉织物抗皱性能的影响。选取了不同紧度的斜纹、平纹2组棉织物试样,测试了其在抗皱整理前后的急弹与延迟回复角、表面形貌和化学结构。在实验基础上,结合双因素方差分析,确认了织物紧度、树脂质量浓度双因素的协同作用对织物抗皱性影响的显著性,分析了双因素单独和协同情况下的作用效果。结果表明:织物紧度、树脂质量浓度分别对织物抗皱性有显著、积极的影响;增加树脂质量浓度,低紧度的棉织物回复角增长幅度高于紧度大的棉织物;树脂质量浓度超过80 g/L时,低紧度棉织物回复角高于同组织结构的高紧度试样。

Influence of fabric tightness and anti-crease finishing on wrinkle recovery of pure cotton woven fabrics

In order to improve the anti-creasy property of cotton fabrics,the influence of the independent and cross-coupling effect of fabric tightness and anti-crease finishing parameters on wrinkle recovery performance of pure cotton woven fabrics were explored.Two groups of pure cotton woven fabrics,twill and plain woven fabrics,were selected as specimens for this research.For each type of fabric specimen before and after the crease-resistant finishing,the instant/slow recovery angle,surface morphology and surface chemical structure were tested.Based on the experimental data,the effects of fabric tightness and resin concentration on wrinkle recovery of cotton fabric were studied.Double-factor analysis of variance was adopted to evaluate the significance of the cross-coupling effect of fabric tightness and resin concentration on wrinkle recovery of cotton fabrics,and the synergistic effect of fabric tightness and resin concentration on wrinkle resistance of cotton fabrics was analyzed.The results show that fabric stiffness and resin concentration demonstrate significant and positive effect on wrinkle recovery of the fabric respectively.When the resin concentration rises,the growth rate of the wrinkle recovery angle of cotton woven fabric with lower fabric tightness is generally larger than that with higher fabric tightness.In addition,when treated by resin with concentration higher than 80 g/L,the winkle recovery angle of lower-tightness fabric is mostly larger than that of higher tightness with same structure.
