在线热熔法涤纶保暖非织造絮片的研制

为了实现热熔法涤纶保暖非织造絮片的在线生产,对热熔粉、远红外粉、纤维原料的配比、纤维网的蓬松度、撒粉条件、热熔加固等工艺进行了研究。结果表明:当热熔粉质量占纤维网质量10%,复合远红外粉质量占热熔粉质量11%,纤维网的蓬松度控制在35～40g/cm3,撒粉高度控制在8～20cm时,可获取较好保暖性能的涤纶非织造絮片。

Development on line of hot melting PET nonwoven wadding with warmth retention property

In order to manufacture the hot melting warmth retention PET nonwoven wadding,the ratio of the heat-bonded powder,far infrared powder and fiber material,the bulkiness of the fiber net,the process of powdering and heat-bonded strengthening were studied. The results indicated that better warmth retention PET nonwoven wadding can be achieved with the amount of heat-bonded powder as 10% of fiber net,the far infrared powder as 11% of heat-bonded powder,the bulkiness of the fiber net as 35～40 g/cm3,the height of powdering is 8～20 cm.
