摘要
Highloft nonwoven was produced by heat bonding of bicomponent polyester fibers. The effect of fiber properties and processing parameters on the mechanical properties of the nonwoven was investigated. The heat bonding processing parameters for the nonwoven were optimized. The results show that the range of processing temperature is wider while the shell melting point of the bicomponent fibers (Tm1) is lower. The best processing temperature is about 15℃ higher than Tm1 while the shell melting point (Tm1) is higher.
