The present invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing a mineral wool, (b) humidifying the mineral wool, (c) placing the humidified mineral wool fibers in contact with particles of binder comprising a mixture of thermosetting reagents, (d) shaping the mixture of mineral wool and binder particles, and (e) heating the shaped mixture to a temperature and for a period sufficient to allow the condensation of the reagents and the formation of an insulation product based on mineral wool bound by an insoluble and infusible organic binder.

An industrial textile has a double warp. Yarns (111, 112) of a first warp and yarns (131, 132, 133, 134) of a weft are bonded to each other according to a first predetermined pattern, and yarns (121, 122) of a second warp and the yarns (131, 132, 133, 134) of the weft are bonded to each other according to a second predetermined pattern. The first predetermined pattern and the second predetermined pattern form a textile structure, which includes the yarns (131, 132) of the weft on a first level (L1) and the yarns (133, 134) of the weft on a second level (L2). The yarns of the weft having smaller diameter are configured to alternate with yarns of the weft having a larger diameter on the first level (L1).

The present invention can provide a fiber having a further enhanced strength while serving as a ceramic fiber. To this end, a composite fiber according to the present invention a first fiber component member made of a material having a volume resistivity of 5×10.sup.−6 to 5×10 .sup.6 Ω.Math.m, or a material of a semiconductor or metalloid; and a second fiber component member comprising a ceramic material, wherein the first fiber component member and the second fiber component member are adjacent to each other such that the first and second fiber component members form a fibrous body.

A combustion membrane (14) for a gas burner (2) comprises a fabric or mesh (21) of interlaced metal threads (22), having two opposite interlacing surfaces (19, 20) which form a combustion surface (19) and an inner surface (20) of the fabric/mesh (21), respectively, wherein the metal threads (22) are formed by twisted metal fibers (22) to form a yarn and: the individual metal fibers (22) are shorter than the yarn (22) formed therefrom, and free ends (22″) of the metal fibers (22) protrude divergently from the yarn (22) along its longitudinal extension and make the yarn (22) hairy, and the metal thread (22) is a yarn (22) of mass per length in the range from 0.8 g/m to 1.4 g/m.

Web material structuring belts that impart structure to a web material during a web material structuring operation and/or structured web material forming operation, method for making same and methods for using same to make structured web materials, for example structured fibrous structures, such as structured sanitary tissue products such as structured toilet tissue, structured paper towels and structured facial tissue are provided.

A power transmission belt includes a belt body made of an elastomer, and a cord made of carbon fibers and embedded in the belt body. The belt tension T.sub.0.2 per 1 mm belt width at 0.2% of a belt extension rate is 70 N/mm or more. The belt tension T.sub.0.5 per 1 mm belt width at 0.5% of the belt extension rate is 220 N/mm or more. The ratio of the belt tension T.sub.0.2 to the belt tension T.sub.0.5 is 0.33 or more.

[Task] The object of the present invention is to provide an industrial two-layered fabric with a long durability which exhibits an excellent surface smoothness and excellent marking characteristics, while at the same time improving wear resistance characteristics to balance warps and wefts. [Solution to the Task] An industrial two-layered fabric formed by binding yarns, diameters of all of the upper surface side warps are set to be the same, diameters of all of the lower surface side warps are set to be the same, diameters of the lower surface side warps are set to be larger than diameters of said upper surface side warps, and at least one, or more than one of said upper surface side warps are woven with said lower surface side wefts to constitute binding yarns binding said at least one upper surface side fabric and said at least one lower surface side fabric.

A woven fabric seam area is provided including a top surface and a bottom surface, with the woven fabric being formed of warp yarns interwoven with weft yarns in a repeating pattern, and either the warp yarns or the weft yarns are formed at least in part of a laser energy absorbent material. Within the fabric seam area yarns formed of laser energy transparent material can be bonded to yarns being formed at least in part of a laser energy absorbent material by laser welds in order to maintain or achieve a desired flexibility and/or shear resistance of the fabric. A method of forming such a fabric seam area is also provided.

According to an example aspect of the present invention, there is provided a yarn (100) comprising: a plurality of monofilaments (101 102, 103, 104) twisted together, and a multifilament or a spun yarn (105) wound around the plurality of monofilaments (101, 102, 103, 104), wherein the multifilament or the spun yarn (105) comprises a bio-based material, a recycled bio-based material or a recycled synthetic material.

The invention is directed to a mineral fibre product having a low water leachable chloride content which is suitable as non-corrosive thermal and/or acoustic insulation.
