  • Patent number: 5733822
    Abstract: The present invention provides composite nonwoven fabric laminates and processes for producing such. The fabric is comprised of a web 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 comprise oxidatively degraded spunbonded filaments and are positioned around and laminated to a web 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 adsorbent products.

  • Patent number: 5614306
    Abstract: Conductive meltblown fabrics are disclosed which have improved strength and hand over conventional conductive meltblown fabrics. Also disclosed is a process for spraying a solution containing a conductive agent into a molten stream of meltblown fibers before they are deposited onto a forming wire. By applying the solution onto the fibers before they are deposited onto the forming wire, the heat of the molten stream vaporizes the solvent carrying the conductive agent and thereby eliminates the need to subsequently dry the formed material. By eliminating the drying step, degradation of the strength and hardening of the hand of the material normally resulting from the wetting and drying of meltblown fabrics are avoided. There is also disclosed a conductive SMS laminate having a conductive meltblown layer sandwiched between two untreated and nonconductive spunbond layers.
