preparation example Construction

[0037] The preparation method of the above-mentioned light and thin high-performance heat-insulating protective clothing fabric includes the following steps:

[0038]In the first step, during the airgel synthesis process, the powder microcapsule phase change material is uniformly dispersed in the airgel layered structure by the percolation method to prevent the leakage of the microcapsule phase change powder during processing and use;

[0039] The second step is to combine the outer and inner non-woven fabrics with the airgel and microcapsule phase change material mixed middle layer through lamination and sewing technology to form a heat insulation layer, so that the heat insulation layer has good performance;

[0040] The third step is to laminate the flame-retardant outer layer, waterproof and moisture-permeable layer, and heat-insulating layer through layer-by-layer sewing technology to form an airtight, flat, and non-damaged light and thin high-performance heat-insulating p...

Abstract

The invention provides a light-weight high-performance heat-insulating protective clothing fabric and a preparation method thereof. The light-weight high-performance heat-insulating protective clothing fabric is prepared by successively compounding the following functional structure layers from a direction close to a fire source to a direction close to human body: a flame-retardant outer layer with flame-retardant effect, a waterproof moisture-permeable layer with waterproof and moisture-permeable effects, and a heat-insulating layer with heat-insulating effect. The heat-insulating layer has a three-layer composite structure, wherein the inner and outer layers are non-woven fabric layers; the middle layer is a mixed layer of aerogel and a microencapsulated phase change material; and the structure has high heat insulation performance, effectively reduces natural thickness and weight of clothing, thereby providing excellent protective properties and wear comfortableness for firefighters. The light-weight high-performance heat-insulating protective clothing fabric has the advantages of light weight, convenience in combination and shaping, good reusability and wide range of application, can be used for clothing in emergency lifesaving environments like fire ground and battle ground, and can be also used as an aerospace protective material.

Description

technical field [0001] The invention relates to a light and thin high-performance heat-insulating protective clothing fabric and a preparation method thereof, in particular to a heat-protective fabric with excellent heat insulation performance, comfort performance and slowing down the release of heat storage energy and a preparation method thereof, belonging to textile composite materials and functional technical textiles. Background technique [0002] Protective clothing is commonly used to protect the human body from hazards, such as various thermal hazards and chemical hazards. Among them, firefighting clothing is the protective clothing worn by firefighters during fire fighting or fire rescue. Usually, in addition to high flame retardancy and heat resistance, excellent heat insulation performance is also required to prevent firefighters from being burned and burned. . At present, the structural design of firefighting clothing used in my country mainly includes four lay...
