The invention discloses a high-strength PET felt and a preparation method thereof. The high-strength PET felt comprises PET fine fibers, water-repellent PET fibers and high-crystallization BICO fibers which are mixed according to a certain weight ratio. Uniformly mixing PET fine fibers, water-repellent PET fibers and high-crystallization BICO fibers according to a certain weight ratio to obtain a mixture; heating the mixture to melt the high-crystallization BICO fibers, and sticking the PET fine fibers and the water-repellent PET fibers to obtain a three-dimensional net-shaped composite material; carding the three-dimensional net-shaped composite material into a net shape and laying the net; and the high-strength PET felt is prepared by needling. The material has the advantages of good performance, such as high strength, light weight, water resistance, high temperature resistance, low VOC (volatile organic compound), low odor, 100% recovery of materials and the like.
本发明公开一种高强度PET毡及其制备方法,包括按照一定重量比例混合的PET细纤维、拒水PET纤维和高结晶BICO纤维。将PET细纤维、拒水PET纤维和高结晶BICO纤维按照一定重量比例混合均匀,获得混合物;加热混合物,使得高结晶BICO纤维熔化,将PET细纤维和拒水PET纤维粘住,获得立体网状复合材料;将立体网状复合材料梳理成网状并铺网;利用针刺制备获得高强度PET毡。本发明具有一些良好的性能,如强度高、质量轻、防水耐高温、低VOC、低气味和材料可100%回收等优点。
