  • Method of making nonwoven fabric comprising splittable fibers
    Patent number: 6692541
    Abstract: The present invention relates generally to a method of making nonwoven fabrics, wherein the fabrics are formed from splittable filaments or staple length fibers having a plurality of sub-components which are at least partially separable. The filaments or fibers are at least partially separated into their sub-components attendant to hydroentanglement, which can be effected on a three-dimensional image transfer device. Improved physical properties, including improved tensile strength, elongation, and Taber Abrasion resistance are achieved.
    Type: Grant

  • Nonwoven surgical sponge with x-ray detectable element
    Patent number: 4718897
    Abstract: A surgical sponge constructed of a nonwoven fabric is provided with an integral x-ray detectable element in the form of an entangled roving which is positioned on one surface of the non-woven fabric. The fabric is produced by placing the x-ray detectable element atop a fibrous web and subjecting the roving and web to hydraulic entanglement to produce a patterned, nonwoven fabric.

  • Absorbent pads
    Patent number: 4551377
    Abstract: An absorbent pad of non-woven fabric having high absorbency and integrity has on one side a layer of binder material for providing a surface having an absorbency reduced with respect to the remainder of the pad, the remainder of the pad being free of binder.
