Patent number: 6200669Abstract: Nonwoven webs are fabricated by forming unitary multicomponent fibers comprising a plurality of individual segments partially exposed at the surface of the fiber; bonding the multicomponent fibers, such as by thermal point bonding, and then hydroentangling the bonded multicomponent fibers with a water pressure from about 400 to 3000 psi wherein the entangling process separates the individual segments of the unitary multicomponent fibers into microfibers and also entangles the fibers to form an integrated nonwoven web. The nonwoven webs include entangled webs of thermoplastic multicomponent fibers and microfibers having partially degraded bond areas comprising from about 5% to about 50% at the surface area of the web.Type: GrantFiled: November 26, 1996Date of Patent: March 13, 2001Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Samuel Edward Marmon, Elisha Seidah Wazeerud-Din, Brett Peter Samuels
