Abstract: The present invention provides a method for producing a continuous filament nonwoven fabric under conditions which modify the surface characteristics of the filament and the fabric formed by the process. A blend of thermoplastic polymers, wherein at least one is a polyolefin polymer and containing a majority polymer component of low MFR, is extruded through a heated die under conditions which are responsible for controlled oxidation of the filament surface of at least one component so that they are capable of efficient bonding. During spinning, the continuous filaments display good drawability and good filament distribution on the collection surface. Preferably, the filaments are drawn to a fine denier (i.e., 5 or less). The corresponding continuous filament fabric possesses desirable strength properties, as a result of high interfilamentary bond strength.

Abstract: 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.
