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

摘要

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/m~2 and the needle-punching density was 300 needle/cm~2, 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 cm~3/cm~2/s when the basis weight was 100 g/m~2 and the needle-punching density was 300 needle/cm~2.
