摘要:
A carrier material comprising at least a first thermoplastic fiber layer (A1) and a second thermoplastic fiber layer (A2), characterized in that at least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.

A solar reflective fibre having a longitudinal axis, the fibre comprising: a substantially continuous primary portion having a first refractive index; and a plurality of secondary portions, each secondary portion having a second refractive index different from the first refractive index. The primary and secondary portions are arranged to run substantially continuously along at least a portion of a length of the fibre, the primary portion providing a host medium within which the secondary portions are provided. The primary and secondary portions are arranged to constitute a dielectric mirror structure whereby a phase of a plurality of scattered beams of radiation each beam being scattered at one of a plurality of respective interfaces between primary and secondary portions interfere constructively with one another thereby to reduce an amount of radiation transmitted through the fibre.

The present invention relates to a heat reflective coated structural article comprising a heat reflective component and a coated structural article component which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge. The coating of the coated structural article consists essentially of a filler material and a inder material wherein the binder material bonds the filler material together and to the substrate and wherein the coating does not bleed through the substrate. Nonlimiting examples of the heat reflective component include, elastomeric coatings, aluminum fiber coatings, acrylic and polyurethane coating systems, ceramic coatings insulating paints, metal pigment paints, metal pigment pastes and aluminum flakes. The heat reflective coated structural article of the present invention may be incorporated into commerical roofing products.
摘要:
the present invention provides a method for the production of bounded non-wovens carriers. The method includes providing a glass staple fiber containing non-woven which is pre-consolidated with a binder. The glass staple fiber non-woven is placed adjacent to one or more non-wovens of synthetic fibers and hydro-dynamically needling at a water beam pressure in the range of 100 to 400 bar.
摘要:
The invention concerns a fibre mat useful for forming bituminous membranes, comprising glass fibres, organic fibres and a binder, characterised in that the organic fibres have a shrinking ratio at 130 DEG C not more than 5 %. The invention also concerns a bituminous membrane comprising a substrate coated, lined or impregnated with a bituminous matrix, wherein the substrate consists of said mat. The mat and the membrane are useful for roofing and/or waterproofing.

摘要:
A method of preparing modified asphalt includes mixing polyethylene (12), such as linear high density polyethylene, with an asphalt composition and heating. The method optionally includes mixing a styrene butadiene rubber (13) with the polyethylene (12) and asphalt (26). The modified asphalt (30) is coated (38) on a substrate material, such as a fiberglass mat or other substrate, imparting strength, durability and waterproofing characteristics. The mixing process suspends the polyethylene and optional styrene butadiene rubber as a three dimensional, reinforcing matrix within the asphalt. One example of a source of polyethylene material (12) includes recycled polyethylene food containers. The recycled polyethylene material (12) is reduced to polyethylene chips (18) together with the optional styrene butadiene rubber (13) and maintained in suspension in the asphalt composition (30) with mixing and heating.
摘要:
A lightweight, high-strength composite fabric (110) suitable for use in a carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric (110) comprises a layer of nonwoven material (116) disposed between a layer of low shrinkage warp strands (112) and a layer of low shrinkage weft strands (114). The layers are stitched or knitted together and the resultant fabric (110) may be coated with a resin or sizing agent (122) to prevent slippage between the several layers of the fabric (110) and impart a measure of stiffness to the fabric (110). The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric (110) may function as a ready-to-use roofing membrane or other high-strength fabric product.
摘要:
The invention concerns a roof-lining material allowing diffusion, which is hydrophobic and/or has a hydrophobic finish and which includes an at least three-layered composite of thermoplastic non-wovens, at least to a major extent of continuous filaments and at least one inner non-woven layer being made at least to a major extent of melt-blown microfibre. One or more of the layers are optionally compacted individually or together by a pattern-embossing process in which the inner melt-blown microfibre layer is provided with a hydrophobic finish and has a weight per unit area of 10 to 100 g/m , preferably 20 to 60 g/m . In addition, the surface of the iner layer is heat-treated to give a film-like layer with residual porosity, thus providing permeability to water vapour. The invention also concerns a method of manufacturing the material. 00000
摘要:
The present invention relates to a method of producing a fabric impregnated with an aqueous binder composition of thinned starch and optionally non-thinned starch. In one aspect, such a method includes providing an aqueous binder composition; providing a fabric, applying an aqueous binder composition to the fabric; and drying the fabric. The invention also relates to the fabric obtained and the use thereof in bituminous membrane layer.
