Cloth

FIELD: textile, paper.

SUBSTANCE: invention is related to heat resistant cloths, used, mostly, for heat insulation. Cloth, which includes woven threads of warp and weft, additionally contains fibrous powdered material.

EFFECT: increased mechanical strength of cloth with preservation of reduced aerotransparent surface of cloth without increase of its thickness, density of weaving, number of layers, etc, and also - improved operational characteristics and economic parametres of 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 (see Asbestos technical products. Handbook, M., "Tsniiteneftehim", 1966, SS-28). The essential features of analogue comprising interwoven warp and weft" match 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, subjected to additional destructive effect, in which the thread is able to process 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" match 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 of the 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 fabric comprising interwoven warp and weft, further comprises fibrous dust-like material.

The essential features of the claimed invention further comprises a fibrous pulverulent material are distinctive signs are the closest equivalent.

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. In 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. Threads contain only those split-off part of the fibers, which are formed in p is acesse the manufacture of the fabric. The tissue contains between threads and fibers of the fibrous dust particles, mainly from the same material of the fabric. When mechanical stresses, and deformations in the process of transportation, installation and operation of thread or lint intertwined (solicitada), gradually blocking the gaps between the threads 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. The fabric also contains asbestos and cotton lint in an amount of 0.01÷0,9% by weight of threads.

To produce the inventive fabric may be known methods. When the required quantity of dust fibrous component may be provided by various methods, for example by coating the finished fabric dust, adjustment dust extraction system in the manufacture of yarns and other

Making fabric using the composition of the fibrous dust particles, owing to skolachivaniya of these particles with the fibers, partially derived from threads during manufacture of the fabric, to reduce Aeroporto the surface of the fabric. This skolachivaniya possible mechanical influences during transportation, installation and operation TKA is I. 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, because participation in skolachivaniya fibrous dust particles reduces Aeroporto surface without special destructive impact.

The fabric comprising interwoven warp and weft, wherein the fabric further comprises a fibrous dust-like material.
