在线热熔法涤纶保暖非织造絮片的研制

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

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。

In order to manufacture the hot melting warmth retention PET nonwoven wadding, the ratio of the heatbonded 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/cm^3, the height of powdering is 8 -20 cm.
