An implant and a process for preparing such an implant are disclosed. The implant includes a porous layer including collagen, a non-porous layer including a collagenic constituent, and a reinforcement component. The non-porous layer is joined to the porous layer and the reinforcement member is embedded into the non-porous layer. The porous layer has a three dimensional density ranging from about 20 mg collagen/cm.sup.3 to about 200 mg collagen/cm.sup.3.

A scrim reinforced roofing membrane comprising a coated scrim layer having a first side and a second side and a first polyvinyl chloride layer on the first side of the coated scrim layer. The coated scrim layer contains a scrim fabric which contains a plurality of warp yarns in a first direction and a plurality of weft yarns in a second direction approximately perpendicular to the first direction. The warp yarns cross the weft yarns at crossing points. The scrim fabric has a polyvinyl acetate coating which is located along the length of the warp yarns and the weft yarns and between the warp and weft yarns at the crossing points. The coated scrim is at least partially embedded in the first polyvinyl chloride layer.

A scrim reinforced roofing membrane comprising a coated scrim layer having a first side and a second side and a first TPO layer on the first side of the coated scrim layer. The coated scrim layer contains a scrim fabric which contains a plurality of warp yarns in a first direction and a plurality of weft yarns in a second direction approximately perpendicular to the first direction. The warp yarns cross the weft yarns at crossing points. The scrim fabric has a polyvinyl acetate coating which is located along the length of the warp yarns and the weft yarns and between the warp and weft yarns at the crossing points. The coated scrim is at least partially embedded in the first TPO layer.

Lightweight, flexible protective fabrics for protecting a person, animal or other object from hot burning materials, hot high heat capacity and/or hot corrosive materials, such as hot molten metal, hot oily liquids (e.g., heating oil), hot gels, hot solids, hot sparks, and hot acids. The lightweight protective fabrics can be used to protect a person, animal or other object from hot molten metals, such as liquid metal zinc heated to a temperature of about 950 F. (510 C.) or greater, hot molten aluminum heated to a temperature of about 1150 F. (620 C.) or greater, burning phosphorus at temperature of about 1550 F. (843 C.) or greater, hot solid iron having a temperature of about 500 F. (260 C.) or greater, hot heating oil having a temperature of about 500 F. (260 C.) or greater, and hot hydrochloric acid having a temperature of about 300 F. (150 C.) or greater.

A self-wrapping, non-woven sleeve for routing and protecting elongate members and method of construction thereof is provided. The sleeve includes an elongate non-woven wall having opposite sides extending along a longitudinal axis of the sleeve. The sides are self-wrapping about the longitudinal axis to provide a tubular cavity. The sides are extendable away from one another under an externally applied force to expose the cavity for insertion of the elongate members, wherein the sides return to their self-wrapped configuration upon removal of the externally applied force. The wall includes discrete first regions of a material and discrete second regions of a material. The first and second regions of material are different and provide the wall with non-uniform physical properties.

A family of selectively absorbable/biodegradable, fibrous composite constructs includes different combinations of biostable and absorbable/biodegradable yarns assembled as initially interdependent, load-bearing components, transitioning to exhibit independent functional properties during in vivo end-use. The family of constructs consists of two groups, one group is made of fiber-reinforced composites of high compliance, absorbable matrices of segmented polyaxial copolyesters reinforced with multifilament yarn constructs, which are combinations of ultrahigh molecular weight polyethylene fibers and at least one absorbable/biodegradable fiber selected from silk fibers and multifilament yarns made from linear segmented, l-lactide copolyesters and poly (3-hydroxyalkanoates, are useful in orthopedic, maxillofacial, urological, vascular, hernial repair and tissue engineering applications. The second group is made of coated and uncoated, warp-knitted mesh constructs for use in hernial, vascular, and urological tissue repair and tissue engineering.

A knit fabric containing a stitch yarn set containing pairs of stitch yarns, a warp yarn set containing in-lay warp yarns, and a weft yarn set containing weft inserted yarns. Each pair of stitch yarns comprises a first stitch yarn and a second stitch yarn, where the first stitch yarn has a two bar first stitch pattern comprising repeating pattern of at least one tricot stitch optionally followed by at least one pillar stitch and the second stitch pattern comprises a mirror image to the first stitch pattern. The first stitch yarn and the second stitch yarn within each pair of stitch yarns are interlinked together, but the first stitch yarn and second stitch yarn of one pair of stitch yarns are not interlinked with first stitch yarn and second stitch yarn of adjacent pairs of stitch yarns.
