汽车座椅用人造麂皮面料的耐沾污性研究

非织造超细纤维人造麂皮绒面革通常作为一种高档的高附加值产品应用于汽车座椅面套,但其表面的超纤结构及较强的吸水性使之在使用中不易打理,特别是遇液态污染物后表现出耐沾污性差的特点。为提升其耐沾污性,文章以某车型座椅人造麂皮面料为例,探究提升其耐沾污性的功能整理技术,并采用马丁代尔法进行耐磨性测试后测试其耐沾污性能变化。结果表明,在2500 r的耐磨测试后,该面料对牛奶、可乐、咖啡、酱油全部保持有4级以上耐沾污效果,在5000 r的耐磨测试后,仅对牛奶、可乐仍具有4级以上耐沾污效果,对咖啡和酱油则无耐沾污效果。

Study on the Stain Resistance of Suedette for Car Seats

As a high-end,high value-added product,nonwoven ultra-fine fiber suedette is usually used in car seat covers.However,its superfine fiber structure and strong absorptivity make it difficult to take care of,especially for liquid contaminants.In order to improve its stain resistance,this paper takes suedette of a certain model car seat as an example to study related functional finishing technology.The Martindale method was used for the change of stain resistance performance after the abrasion resistance test.Results showed that after the abrasion resistance test at 2500 r,the stain resistance of suedette for milk,cola,coffee,and soy sauce was maintained above level 4.However,after the abrasion resistance test at 5000 r,the suedette only maintained the stain resistance above level 4 for milk and cola,and for coffee and soy sauce,it has no stain resistance effect.
