Fabric

FIELD: textiles; paper.

SUBSTANCE: invention refers to heat-resisting fabrics mainly used for heat insulation. Fabric includes woven core and filling threads. Fabric surface represents alternating projections and cavities containing holes. Surface area of fabric, which is occupied with projections, is not less than 50% of total surface area. Increase in mechanical strength of fabric is reached at maintaining decreased aerotransparency of fabric surface without increase in its thickness, interweaving density and number of layers.

EFFECT: improving operating and economic characteristics of fabric heat insulation.

 

The invention relates to heat-resistant fabrics, mainly used for thermal insulation.

Analogous to the claimed invention is a fabric comprising interwoven warp and weft, the surface of which consist of alternating protrusions and containing holes basin, with a surface area of tissue per protrusions is less than 50% of the total area of the surfaces (see Asbestos technical products. Directory M: Tsniiteneftehim, 1966, p.17-28). The essential features of analogue comprising interwoven warp and weft, the surface are of alternating protrusions and containing holes depression coincided with the essential features of the claimed invention.

The disadvantage of analog is the need to use to ensure the effectiveness of the insulation heavy fabrics or several layers of tissue.

The closest analogue of the claimed invention is a fabric comprising interwoven warp and weft, the surface of which consist of alternating protrusions and containing holes basin, with a surface area of tissue per protrusions is less than 50% of the total area of the surfaces, and the thread is subjected to additional destructive effect, in which the threads of the way the s in the transport fabric, installation and operation of isolation to the partial removal from the surface of the threads of the individual fibers and solutionyou split fibers (see RF patent №2237115, IPC7D03D 15/12, 2004). The essential features closest analogue comprising interwoven warp and weft, the surface are of alternating protrusions and containing holes depression coincided with the essential features of the claimed invention.

The disadvantage is the closest analogue is the reduction of the mechanical strength of the tissue due to special destructive impact and removal of fiber during transportation, installation and operation of the fabric.

The challenge which seeks the invention is to increase the mechanical strength of the fabric while maintaining the reduced aeroprogres the surface of the fabric without increasing its thickness, the density of the weave, the number of layers, etc. that significantly improves performance and economic performance insulation.

To achieve the technical result in tissue, comprising interwoven warp and weft, the surface of which consist of alternating protrusions and containing openings of the cavities, the surface area attributable to the protrusions is not less than 50% of the total area of surfaces.

the Essential features of the claimed invention, the surface area, the attributable to the protrusions is not less than 50% of the total area of the surfaces are different from the characteristics most similar analogue.

The fabric is a cloth made by weaving basic and weft threads on a loom. The fabric can be plain, twill, etc. weave, to be double, etc. Both surfaces of the fabric contain alternating protrusions and depressions. In the hollows are through holes (openings). The fabric comprises filaments (fibers)which are not subjected to special destructive mechanical stress (e.g., crushing), resulting threads are not capable of partial removal from the surfaces of the filaments of the individual fibers during transport, installation and operational loads. Filament fabrics have sufficient deformation capacity to compression fabric on its surface the thickness of the tissue is decreased with a simultaneous increase in the area of the protrusions and the reduction of the area of the depressions and holes so that the tabs had at least 50% of the total area of the corresponding surface of the fabric.

A specific example of the inventive fabric is fabric, the threads of which are asbestos fibers and cotton fibers, which are not subjected to special destructive impact. Fabric subjected the sea otter is rirovanie with such compression, that the tabs have 51÷55% of the surface area of the fabric.

To produce the inventive fabric may be known methods. Using threads having a sufficiently high deformation ability. Manufactured fabric calendarbut, pressed or formed by other methods to achieve the necessary ratio of the squares of the projections and depressions.

The manufacture of cloth, which due to deformation of the threads in the process of manufacture of the fabric on the protrusions is not less than 50% of the surface area of the tissue, reduces Aeroporto the surface of the fabric. Reduction aeroprogres surface helps reduce gas flow through the fabric during operation, and, accordingly improve the insulating characteristics of the tissue. This does not compromise the mechanical strength of the tissue, since there is no specific destructive effect on the threads of the fabric.

The fabric comprising interwoven warp and weft, the surface of which consist of alternating protrusions and containing holes of depression, characterized in that the surface area of tissue per protrusions is not less than 50% of the total area of the surfaces.
