  • Durable hydrophilic nonwoven mat
    Patent number: 7329623
    Abstract: A nonwoven web of a wettable fiber matrix, wherein the wettable fiber matrix are thermoplastic polymeric fibers blended with at least one hydrophilic melt additive. In alternate embodiments, the nonwoven web further includes binder fibers which may be wettable or non-wettable or combinations of both.
    Type: Grant
    Filed: August 30, 2002
    Date of Patent: February 12, 2008

  • Durable hydrophilic nonwoven webs and articles formed therefrom
    Patent number: 6696373
    Abstract: Nonwoven webs in accordance with the present invention include multicomponent fibers bonded by a multiplicity of bond sites to form a coherent web. The multicomponent fibers include a first component formed of a hydrophobic polypropylene and a second component formed of a blend of a hydrophobic polyolefin and a hydrophilic melt additive. This second component is disposed at the surface of the fibers. The hydrophilic melt additive-modified polyolefin component can be arranged in various configurations in the cross-section of the fiber and the fibers can have various cross sections. For example, the hydrophilic component can occupy a portion of the surface of the fiber, as would occur for example with a side-by-side or segmented pie multicomponent fiber configuration. Alternatively, the modified hydrophilic polyolefin can occupy substantially the entire surface of fiber, as for example by producing the fibers in a sheath core configuration with the hydrophilic modified component forming the sheath.
