Manufacturing Technique and Physical Properties of Environment-Protective Composite Nonwoven Fabrics

Abstract:

Rapid technical advancement threatens the earth ecology, driving people by degrees to develop green energy and green products. Tencel^® fiber uses natural fibers. Products made of Tencel^® fiber could be biodegraded, which solves the problems for the increasing consumptions of disposable nonwoven product. In this research, Tencel^® fiber, polylactic acid (PLA) fiber, and high absorbent fiber (HAF) were used to produce Tencel^®/PLA/HAF composite nonwoven fabrics. Among the nonwoven processing parameters, to increase the Tencel^® fiber content helped heighten the water absorbency. When there were 80 wt% Tencel^® fibers, the basis weight was 100 g/m² and the needle-punching density was 300 needle/cm², the Tencel^®/PLA/HAF composite nonwoven fabric exhibited the optimum water absorbency in cross machine direction (CD), which was 5.0 cm. The air permeability of the Tencel^®/PLA/HAF composite nonwoven fabrics reached 164.4 cm³/cm²/s when the basis weight was 100 g/m² and the needle-punching density was 300 needle/cm²
