Abstract

This study uses Far-infrared fiber (FIR), PET fiber, and Low-Tm PET fiber to prepare FIR/PET/Low-Tm PET composite nonwoven. In the processing, the FIR fiber was constant as 10 wt%, and low-Tm PET fiber was varied from 10, 30, 50, 70 and 90 wt% in order to understand thermo-bonding effect on nonwovens. After being hot-pressed, the FIR/PET Low-Tm PET composite nonwoven was evaluated in terms of tensile strength, bursting strength, air permeability, stab resistance and FIR emissivity. The study shows that tensile strength along cross machine (CD) is higher than that along machine direction (MD), and stronger with increase of low-Tm PET fiber. However, the bursting strength and stab resistance generates the weak property only at 50 wt% of low-Tm PET fibers. The air permeability and far-infrared emissivity display optimal when the low-Tm PET fiber contained 90 wt%.
