覆膜加工后对棉织物防钻绒性能的影响

The Effect of Film-coated Processing on the Down Proof Performance of Cotton Fabrics

为开发新型防钻绒羽绒制品,采用粘合工艺对棉织物进行覆PE膜加工.实验采用滚箱法对比测试了覆膜前后棉织物的钻绒性能差异;采用平板法对比测试了覆膜前后棉织物羽绒制品的保温性能,具体包括克罗值及保温率;采用斜面悬臂法对比测试了覆膜前后棉织物的硬挺度即柔软度的变化.结果表明:对棉织物进行覆膜处理后,其防钻绒性能得到极大改善,达到优秀防钻绒性标准;覆膜前后保温性能无明显变化,覆21g/m2透气PE膜后棉织物保温性能甚至稍有提高;覆膜后棉织物柔软度虽略有下降,但无明显变化.

In order to develop a new type of down proof down products,the cotton fabric is coated with PE film by the bonding process.In the experiment,the difference between the down proof performance of the cotton fabric before and after the film-coated was tested by the roller box method.The warmth retaining property of the cotton fabric before and after the film-coated was tested by flat panel method,including the heat transfer coefficient,Clo value and thermal insulation rate.The change of the stiffness or the softness of the cotton fabric before and after the film-coated was tested by using the inclined plane cantilever method.The results showed that the down proof performance of the cotton fabric was greatly improved after being coated with the film,and the excellent down proof performance was achieved.Before and after the coating,the warmth retaining property did not change significantly.After the cotton fabric was coated with the breathable PE film of 21 g/m2,the warmth retaining property was even slightly improved;Although the softness of the cotton fabric after the film-coated fell slightly,but there was no obvious change.
