Abstract
In this study fireretardant polyester fibers FRPFs which are hollow and have a 3Dcrimp shape were processed using nonwoven manufacturing technology to create fireretardant fibrous material The content of lowT m fibers 10 20 30 40 50 and number of layers of loose nonwoven sheet 1 2 3 4 5 layers were changed to determine tensile strength and elongation thermal conductivity air permeability and the limiting oxygen index The purposes of this study are to develop a manufacturing procedure for convenient installation of thermal insulation material and improve the application of fiber materials in thermal insulation Experimental results demonstrate that due to the loose nonwoven sheet combined with needle punching nonwoven sheets tensile strength FRPFs increased to 100 The contents of the polyester lowmeltingtemperature fiber and the number of combined layers affected thermal conductivity results In the test for the limit oxygen index the optimal sample was manufactured using 778 dtex FRPFs 10 PET lowmeltingtemperature fiber and 5 layers of loose nonwoven sheet The limit oxygen index is 35
