ABSTRACT:
A process for making spunlaced nonwoven fabrics comprised of fusible fibers and non-fusible staple length fibers. The preferred process comprises wet-laying a mixture of fusible and non-fusible staple length fibers into a nonwoven web and then lightly bonding the web to melt the fusible fibers. Optionally, the bonded web is then wound on a roll so the web can be easily transported. Thereafter, the lightly bonded web is hydraulically needled to entangle the fibers in a three-dimensional state. The hydraulically needled web is then optionally dried to remelt the fusible fibers and improve durability and abrasion resistance. The resulting spunlaced nonwoven fabrics made by the inventive process are useful in apparel and wiper applications.
