Cloth refers to a heat-resistant fabrics, mainly for thermal insulation. The fabric is made of threads, capable of mechanical effects to the partial removal from the surface of the threads of the individual fibers and solutionyou split fibers. This fabric differs effective insulation.
The invention relates to heat-resistant fabrics used mainly for thermal insulation.
Analogous to the claimed invention is a fabric comprising interwoven warp and weft (see Y. A. Baturin. The manufacture of asbestos textiles. M.: Chemistry, 1981, S. 122-125; 133-138). 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 prototype of the claimed invention is a fabric comprising interwoven warp and weft (see Asbestos and technical products. The Handbook. M: NIITA-Neftekhim, 1966, S. 17-28). The essential features of the prototype including PE the STATCOM prototype is also the need to use to ensure the effectiveness of the insulation heavy fabrics or several layers of tissue.
The problem to which the invention is directed, is the effectiveness of the insulation by reducing passing through the fabric heat flows by reducing the possibility of passing through the fabric removes heat gas streams (e.g., convection) due to the decline aeroprogres the surface of the fabric without increasing its thickness, density weave (weight), number of layers, etc.
To achieve the technical result fabric comprising interwoven warp and weft made of threads, capable of mechanical influences during 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.
The essential features of the claimed invention “made of threads, capable of mechanical influences during transportation, installation and operation of isolation to the partial removal from the surface of the threads of the individual fibers and solutionyou split fibers are different from the characteristics of the prototype.
The fabric is a cloth made by weaving basic and weft threads on dactory made fabric, contain fiber, capable of mechanical influences on the fabric to the elimination of thread, with most useplease fibers cleaved not completely, remaining in a portion of its length recorded in the threads. Further mechanical influences split-off part of the fibers and some completely usapurchase fibers intertwined (solicitada), blocking the gaps between the threads.
A specific example of the inventive tissue is the tissue type at-16, the threads of which are asbestos fibers, cotton fibers, and the fibers are subjected to special destructive mechanical stress (for example, destructive fiber, some forms of waste fibers and others). Destructive fibers have a high capacity for removal compared to conventional fibers. When this destructive mechanical action is chosen in such a way as to ensure mainly partial, but not complete removal of the fibers.
To produce the inventive fabric may by known methods on a loom.
Making fabric using the composition yarns of fibers having a high capacity for removal due to the additional destr the ski impacts during transportation of the fabric, the installation and operation of tissue in part of the insulation to reduce Aeroporto the surface of the fabric. This contributes to the reduction of gas flows (e.g., convection), passing through the fabric during operation and, accordingly, reduce heat, i.e. improves the insulating properties of the fabric. For more effective isolation is not required increasing the thickness of the fabric, the number of insulating layers, the density of the weave and other
The fabric comprising interwoven warp and weft, wherein the fabric is made of threads, capable of mechanical effects to the partial removal from the surface of the threads of the individual fibers and solutionyou split fibers.
