摘要:
The present invention provides a laminiferous nonwoven fabric with a high woodpulp content suitable for use in wipes, absorbent articles and other applications, and a method of making the same. The laminiferous nonwoven comprises 3 layers bonded together, where the outer layers are lightweight meltspun webs and the middle layer comprises mainly woodpulp fibers. Each of the first (3), second (2) and third (4) nonwoven layer are preferably first formed separately and individually to be self-supported webs, whereafter the three self-supported webs are brought together essentially immediately before bonding them together. When used as a substrate for wet wipes, the inventive fabric exhibits a combination of several useful properties; good wet and dry softness and bulk, good wet abrasion resistance and low wet linting propensity, and where the majority raw material is woodpulp.
