A textile with an electrically conductive first side and an electrically conductive second side where the two sides are separated by an electrically insulating part of the textile and where the electrically conductivity is provided by a graphene coating on the respective sides and where a capacitance can be formed between the respective conductive sides.

The present invention relates to a composite comprising a nonwoven fabric being the substrate of the composite, wherein the nonwoven fabric comprises a polymer (A) selected from the group consisting of polyethylene, polypropylene, polyethylene terephthalate and polyamide; and a coating layer, wherein the coating layer comprises a polymer (B), wherein said polymer is an ethylene copolymer, preferably a polar ethylene copolymer; whereby the coating layer overlays at least one surface of the nonwoven fabric; and whereby the composite has a water vapor transmission rate (WTVR) according to ASTM E-96 ((water cup method) at 38° C. at 50% RH at the outside of the sample and 100% RH at the inside of the samples) of more than 50 g/[m.sup.2/24 h], preferably of more than 100 g/[m.sup.2/24 h].

Disclosed herein is a medical implant component comprising a composite biotextile, which biotextile comprises i) a polyolefin fibrous construct comprising at least one strand with titer of 2-250 dtex, tensile strength of at least 10 cN/dtex and comprising high molar mass polyolefin fibers and ii) a coating comprising a biocompatible and biostable polyurethane elastomer comprising a polysiloxane segment and/or having one or more hydrophobic endgroups, wherein the polyurethane coating is present on at least part of the surface of the biotextile and in an amount of 2.5-90 mass % based on composite biotextile. Such composite biotextile, like a partly coated woven fabric, shows an advantageous combination of good biocompatibility, especially hemocompatibility, high strength and pliability, and laser cuttability; allowing to make pieces of fabric having well-defined regular edges that have high suture retention strength. The invention also provides a method of making said composite biotextile. Further embodiments concern the use of such biotextile in or as medical implant component for an implantable medical device and the use of such medical implant component in making an implantable medical device; such as in orthopedic applications and cardiovascular implants. Other embodiments include such medical devices or implants comprising said medical implant component.

Disclosed herein is a method of making a composite fabric for use in or as a medical implant component, the method comprising steps of providing a textile comprising at least one strand having titer of 2-250 dtex and comprising fibers made from a biocompatible and biostable synthetic polymer; determining locations on the textile where a cut is to be made for an intended use of the textile; optionally pretreating the textile at least at the determined locations on at least one side of the textile with a high-energy source to activate the surface; solution coating the textile at least at a determined location with a coating composition comprising a biocompatible and biostable polyurethane elastomer and a solvent for the polyurethane; removing the solvent from the coated textile; and laser cutting the coated textile as obtained at least a one coated location with an ultra-short pulse laser; to result in a composite biotextile wherein polyurethane is present in an amount of 2.5-90 mass % based on composite biotextile and polyurethane is present at least at a laser-cut edge. Such composite biotextile as made shows an advantageous combination of good biocompatibility, especially hemocompatibility, high strength and pliability, and has well-defined regular edges that have high suture retention strength. Further embodiments concern the use of such composite biotextile in or as medical implant component for an implantable medical device; such as in orthopedic applications and cardiovascular implants. Other embodiments include such medical devices or implants comprising said composite biotextile or medical implant component.

A smart material includes a composite textile that includes a textile substrate and a material disposed via an additive manufacturing technique onto the textile substrate based on an additive manufacturing pattern. The composite textile includes a gradient in least one of mechanical property, material property, or structural property and/or exhibits a change in at least one mechanical property, material property, or structure in response to at least one external stimulus.

Hemp fibers may be disposed throughout or in selected portions of a compression garment (e.g., glove, posture support garment, pants, leggings, tights, shorts, long sleeve top, short sleeve top, sock, etc.). The hemp fibers deployed in the compression garment enhance the durability of the compression garment, and imparts various advantageous properties (e.g., anti-microbial or anti-bacterial, mildew-resistant, odor reduction, moisture wicking, etc.) to the compression garment, enabling the compression garment to be provided with comfort and style.
