  • High bulk nonwoven sorbent with fiber density gradient
    Patent number: 5811178
    Abstract: Disclosed is an improved high sorbency nonwoven fabric and its use particularly as an oilsorb material. The high sorbency nonwoven is preferably made by multi-bank meltblowing and different perturbing thermoplastic fibers of, for example, propylene polymers in separate banks to provide a fiber density gradient through the thickness of the fabric. The sorbent nonwovens have high bulk and strength, oil capacity and oil absorption rates making them particularly suited to such applications. Treatments and additives for such materials are also disclosed.
    Type: Grant
    Filed: November 15, 1996
    Date of Patent: September 22, 1998
    Assignee: Kimberly-Clark Worldwide, Inc.
