    摘要： A wound dressing which acts as a temporary synthetic skin is provided for the eventual healing of tissue partially or completely denuded of skin. The dressing is a unitary structure which is stretchable in two dimensions and is comprised of an outer component and an inner component. The outer component is a microporous membrane permeable to gases but impermeable to micro-organisms. The inner component is a three dimensional matrix structure made of at least two substantially coextensive layers of knitted fabric each bound into the other at closely spaced points to retain stretchability. Each fabric layer is knitted from threads spaced from each other at such a distance that cellular elements from the denuded tissue may invade the dressing to promote healing. The inner component must be thick enough to allow for uniform invasion by cellular elements from the denuded wound, but not so thick so as to allow a large portion of the dressing to be filled by tissue exudates and body fluids, rather than cellular elements representing fibroblastic ingrowth, and not so thick as to prevent infection within such an accumulation from being recognized.

    摘要： Layers of thin thermoplastic film are brought into contact with opposite surfaces of superposed layers of absorbent material, such as sheets of fibrous crepe paper of facial quality, rayon fibers, or flexible polyurethane foam. The layers of plastic film are covered with a loosely-woven cotton scrim or gauze (or with spun-bonded nylon). Additional layers of the thin plastic film may then cover the exterior surfaces of the scrim layers. The multi-layer article thus formed is then compressed and heated to melt the plastic films. The melted plastic bonds the scrim to the paper, separating as it melts to communicate the absorbent paper core with the exterior of the pad and to gather itself about the threads of the scrim in wrapping, covering engagement. The resultant pad is highly absorbent upon contact with a liquid, yet the absorbed liquid will not ''''bleed'''' back from the pad thus making it highly desirable as a surgical sponge or bandage.

    摘要： Absorbent surgical towels with reduced lint particle generation are provided. The surgical towels are formed from fibrous substrates containing binder material that limits lint particle generation to 5,000 or less according to INDA standard test 160.1. The binder material can limit lint particle generation to 500 or less.
