Abstract: The present invention is directed to a fabric composite comprising nylon or polyester fibers having flame-retardant properties without sacrificing many of the desirable properties of the fabric composite. The fabric composite may have external fabric layers (e.g., nylon sheets, etc.) each internally coated with a flame-retardant layer and attached to one another through a thermoplastic polyurethane film. The present invention also provides methods of making such fabric composites.

Abstract: A composite fabric includes: a fabric backing; an adhesive layer; a midlayer barrier bonded to the fabric backing by the adhesive layer; and an external barrier bonded to the midlayer barrier, wherein the composite fabric has a hydrostatic pressure resistance of at least 100 psi and is sufficiently flexible such that it can be formed into a tube and everted. A process and an apparatus for producing the composite fabric are also disclosed. The composite fabric is particularly suitable for use as a liner in a cured-in-place pipe repair method.

Abstract: A method for preparing a composite fabric includes: casting a foamed liquid adhesive onto a smooth release-coated web; applying a fabric to the wet adhesive; fixing the adhesive to the fabric by drying; removing the release-coated web from the adhesive coated intermediate; depositing onto an embossed casting substrate a layer of liquid skin coat composition; applying the porous adhesive layer of the adhesive-coated intermediate to the wet skin layer; drying to fix the skin layer to the adhesive-coated intermediate; and separating the embossed casting substrate from the dried composite to provide the composite fabric. The resulting composite fabrics look and feel like soft shell composite fabrics.

Abstract: A method of forming a composite fabric includes bonding an adhesive layer to a web such that the adhesive layer conforms to surfaces of the web without sealing all web pores, and bonding a barrier layer to the adhesive layer, wherein the composite fabric MVT is at least 25% of the barrier layer MVT; and/or the composite fabric air permeability is at least 20% of the barrier layer air permeability. A composite fabric includes a web, a barrier layer and an adhesive layer therebetween, wherein: (a) the adhesive layer is conformingly bonded to structural members of the web without sealing all pores; (b) the adhesive layer is bonded to the barrier layer; (c) the composite fabric hydrostatic resistance is greater than 200 mbar; and (d) the composite fabric moisture transmission rate is greater than 600 g/m2/24 h and greater than 3000 g/m2/24 by ASTM E96, procedures B and BW, respectively.

Abstract: An air-permeable composite fabric is provided. The composite fabric has an inner fabric layer, an outer fabric layer, and an intermediate vapor barrier. The vapor barrier is selected from adhesive material and an adhesive/membrane combination designed so the composite fabric has a level of air permeability to allow air flow between the first fabric layer and the second fabric layer and a variable level of water vapor diffusion resistance that decreases as air speed impinging on the composite fabric increases.

Abstract: The invention is directed to copolymers, which can be formed into water vapor permeable, water resistant membranes suitable for use in garments, tents, etc. A copolymer includes a random distribution of a soft segment comprising a hydrophilic soft segment and up to about 30 wt % of a hydrophobic soft segment, a hard segment, a cross-linking segment comprising a pendant alkoxysilane, and at least two terminal groups comprising at least one of an amine and an isocyanate having a functionality of at least 2, wherein a number average molecular weight (Mn) of the copolymer is at least about 10,000.

Abstract: A process of laminating textiles for producing air-permeable or moisture-permeable laminated textile materials involves generating a discontinuous layer of adhesive with a precise pattern of voids by means of temporarily introducing sets of parallel yarns or, alternatively, mesh-like webs in contact with an initially uniform layer of adhesive temporarily carried on a release-coated carrier. After the adhesive layer and the mesh-like web have been pushed into contact with a first fabric layer, the release-coated carrier is stripped away, along with the mesh-like web, from the first fabric layer. The adhesive layer remaining on the first fabric layer will exhibit a discontinuous pattern that is complementary to the mesh-like web pattern. Subsequently, a second fabric, or film, is bonded to the exposed adhesive surface on the first fabric to create a laminated material exhibiting air permeability or moisture permeability.
