Mechanical Properties of Nonwoven Wiping Material with Different Spunlace Processes

摘要

A new wiping material made through wet-laid and aquajet-spunlace nonwoven technology has been developed,which is composed of wood pulp and viscose staple fibers.The aim of this paper is to analyze the microstructures of wet-laid and aquajetspunlace material and wet-laid preliminary spunlace material,and elucidate the stretching and bending mechanism of machine direction (MD) and cross-machine direction (CD).The results suggest that composite material is mainly formed by wood pulps,while viscose fibers serve as the reinforcement.Meanwhile,spunlacing improves the entanglement and cohesion between wood pulp and viscose staple fibers.In spite of the slight loss in breaking strength,fluffiness,hand feeling and elongation of the material after spunlacing have been improved significantly.
