Artificial fiber mutualism mixing composite material with warmth retention, heat insulation and sound absorption functions and preparation method and application thereof

Abstract

The invention discloses an artificial fiber mutualism mixing composite material with the warmth retention, heat insulation and sound absorption functions and a preparation method and application thereof. The fiber mutualism mixing composite material is formed by direct spinning of polymer raw materials and airflow thermal phase mixing cohesion, the fiber in the material is generated by polymer particle raw materials on different spinning components on the same device within the same time and mixed through the airflow mixing device to form a mutualism fiber assembly, and the material has the thermal dual-fiber curling characteristic, the high breathability high heat preservation, high water repellency, high winding and twisting resistance, and is light, skin-friendly, washable, capable of achieving warmth retention and heat insulation and soft.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to a man-made fiber symbiotic hybrid composite material with heat-retaining, heat-insulating and sound-absorbing properties, its preparation method and application. Background technique [0002] The various known man-made fiber thermal insulation and sound-absorbing materials are all made of a ready-made fiber after being loosened, and bonded by an adhesive to form a thermal insulation material, and there are also no adhesives but reinforced by quilting. thermal insulation material. There are also thermal insulation materials mixed with fibers of different finenesses, and their common feature is that at least one source of fibers is made of existing, ready-made fibers as raw materials, and the fibers are all short fibers of discontinuous length. The disadvantage of such thermal insulation materials is that they are easy to loosen and agglomerate when used, and are not res...

AI Technical Summary

Problems solved by technology

The disadvantage of this kind of thermal insulation material is that it is easy to loosen and agglomerate when used, and it is not resistant to rubbing. It needs to be reinforced by quilting or other methods when using it.

[0003] The existing various artificial fiber thermal insulation materials have the disadvantages of long production cycle, labor-intensive use, easy breakage, and high overall manufacturing cost.
