COMPOSITE NONWOVEN FABRICS

摘要

The present invention provides composite nonwoven fabric laminates and processes for producing such. The fabric (10) is comprised of a web (11) of thermoplastic filaments laminated to at least one other web. Preferably, the filaments are spunbonded continuous polyolefin filaments which have an oxidatively degraded outer sheath portion to promote better interfilamentary bonding and improved fabric laminate strength. In a preferred embodiment, two outer nonwoven webs (11, 13) comprise oxidatively degraded spunbonded filaments and are positioned around and laminated to a web (12) of meltblown microfibers thus forming an spunbond/meltblown/spunbond fabric. Additionally, a stretch compatible fabric may be formed in which a web of oxidatively degraded filaments is laminated to an elastic web. The fabrics of the invention may be advantageously used in numerous applications such as medical garments and disposable absorbent products.
