Problems solved by technology

[0005] In home textile products, traditional sound-insulating materials are extremely difficult to apply. Thin-layer fabrics have never appeared in sound-insulation research, and there are no sound-absorbing and sound-insulating fabric products at present. The preparation technology of thin-layer fabric sound-insulating materials in the home textile industry is extremely lacking

preparation example Construction

[0028] A preparation method of a honeycomb element structure sound-insulating fabric of the present invention comprises the following steps:

[0029] (1) Weave hollow polyester fibers into a porous fabric with a pore size less than or equal to 1mm, use the porous fabric as a base, and use aluminum with a purity of 99.99% as a target, and coat a layer of thickness on the surface of the base by magnetron sputtering For the aluminum film of 300-800nm, the porous fabric layer of the aluminized film is obtained;

[0030] (2) Weave a special-shaped composite fiber layer with special-shaped cross-section fibers, and the special-shaped cross-section fibers can be selected from one or more of T-shaped composite cross-section fibers, Y-shaped composite cross-section fibers or triangular cross-section fibers; The cross-section fiber is formed by connecting 4-5 fibers with a T-shaped cross-section; the Y-shaped composite cross-section fiber is formed by connecting 4-5 fibers with a Y-shap...

Embodiment 1

[0036] This embodiment includes the first porous fabric layer 1, the first metal film layer 2, the special-shaped composite fiber layer 3, the second metal film layer 4 and the second porous fabric layer 5 connected successively by quilting; The porous fabric layer 1 and the second porous fabric layer 5 are respectively composed of hollow polyester fibers; the first metal film layer 2 and the second metal film layer 4 are respectively aluminum film layers; the pattern shape formed by the quilting It is honeycomb shape 6 .

[0037] The special-shaped composite fiber layer 3 is woven by special-shaped cross-section fibers, and the special-shaped cross-section fibers are T-shaped composite cross-section fibers, Y-shaped composite cross-section fibers, and triangular cross-section fibers; image 3 , the T-shaped composite cross-section fiber described in this embodiment is formed by connecting 4 fibers 7 whose cross-sectional shape is T-shaped; according to Figure 4 , the Y-shap...

Embodiment 2

[0045] This embodiment includes the first porous fabric layer 1, the first metal film layer 2, the special-shaped composite fiber layer 3, the second metal film layer 4 and the second porous fabric layer 5 connected successively by quilting; The porous fabric layer 1 and the second porous fabric layer 5 are respectively composed of hollow polyester fibers; the first metal film layer 2 and the second metal film layer 4 are respectively aluminum film layers; the pattern shape formed by the quilting It is honeycomb shape 6 .

[0046] The special-shaped composite fiber layer 3 is woven from special-shaped cross-section fibers, and the special-shaped cross-section fibers are selected from T-shaped composite cross-section fibers, Y-shaped composite cross-section fibers and triangular cross-section fibers; Figure 5 , the T-shaped composite cross-section fiber described in this embodiment is formed by connecting 5 fibers 7 whose cross-sectional shape is T-shaped; according to Figur...

Abstract

The invention relates to a honeycomb element structure sound insulation fabric and a preparation method thereof. The fabric comprises a first porous fabric layer, a first metal film layer, a special-shaped composite fiber layer, a second metal film layer and a second porous fabric layer which are sequentially connected through quilting seams; the first porous fabric layer and the second porous fabric layer are respectively composed of hollow polyester fibers; the first metal film layer and the second metal film layer are aluminum film layers respectively; patterns formed by the quilting seamsare in a honeycomb shape.

Description

technical field [0001] The invention relates to a fabric and a preparation method thereof, in particular to a sound-insulating fabric with a honeycomb element structure and a preparation method thereof. Background technique [0002] With the development of social economy and science and technology, people's consumption concept and demand for various textile products are also constantly changing. They not only have requirements for the appearance and comfort of textiles, but also pay more and more attention to the functionality of fabric materials. Therefore, various A new kind of fabric came into being. [0003] Textile sound-absorbing and sound-insulating materials, as the name implies, are composite materials processed from textile fibers and applied in the field of sound-absorbing and sound-insulating materials. Since it was reported in the literature in 1973, textile materials have become a research hotspot in the field of sound absorption and insulation due to their po...
