A kind of sound-insulating multi-layer coated knitted fabric

Abstract

The invention discloses soundproof multi-layer film-covered knitted fabric. The fabric comprises a surface layer, a connecting layer and a lining; the surface layer and the lining are connected to the upper end surface and the lower end surface of the connecting layer through knitting; the outer surface of the surface layer is covered with a polyurethane film a; the outer surface of the lining is covered with a polyurethane film b; the surface layer adopts doubled and twisted filaments formed by doubling and twisting aluminum fiber filaments and hollow nylon filaments; the lining adopts ultrafine polyester fiber filament / aluminum fiber filament core-spun yarn, and covering fibers of the ultrafine polyester fiber filament / aluminum fiber filament core-spun yarn are cotton and bamboo charcoal polyester fibers; and the connecting layer of the fabric adopts core-spun yarn, core yarn adopts polyester fiber high-stretch yarn, after the fabric is formed, with shrinkage of the high-stretch yarn, staple fibers covering the surface of the core yarn can be accumulated, the stable gap between the upper layer and the lower layer can be well kept, low-melting-point polyester fibers are melted through moderate heating and then are cooled, and the adjacent fibers can be bonded together by the low-melting-point polyester fibers, so that the fabric has the shape keeping ability under certain pressure.

Description

technical field [0001] The invention relates to a knitted fabric, in particular to a sound-insulating multi-layer coated knitted fabric. Background technique [0002] With the continuous development of science and technology, textile fabrics that meet people's different needs emerge in an endless stream to meet the needs of consumers and play an increasingly important role in people's daily life. [0003] Textile materials have become a research hotspot in the field of sound absorption and insulation due to their porous structure, good processability, and light and thin materials. In the field of home decoration, automotive interior manufacturing, construction, recording studios, and stages, it has broad application prospects. [0004] Textile materials can be attributed to porous sound-absorbing materials because of their looseness, softness and porosity. According to the sound absorption mechanism of porous sound-absorbing materials, when sound waves are incident on the ...
