Problems solved by technology

Good thermal protection can be obtained by wearing multiple layers or heavy clothing, but it will reduce the heat and moisture transfer performance and cause excessive physiological heat load, so that firefighters need more frequent and longer breaks during work to eliminate Fatigue and self-generated physiological heat load, which reduces efficiency
Therefore, the biggest defect of current firefighting clothing is that it cannot achieve good heat insulation performance and comfort performance at the same time.

Embodiment 1

[0026] Such as Figure 4 As shown, the basalt fiber / carbon fiber cloth of the fireproof outer layer 1, the shape memory alloy fiber of the heat insulation layer 2, the waterproof breathable layer 3, and the outlast acrylic fiber / cotton cloth of the comfort layer 4 are combined in sequence, and the U-shaped shape memory alloy fiber and The polytetrafluoroethylene film composite cloth is set between the basalt fiber / carbon fiber cloth and outlast acrylic fiber / cotton cloth layers. The arch of the U-shaped shape memory alloy fiber is fixed at a certain position on the basalt fiber / carbon fiber cloth, and this position corresponds to the interweaving part of the carbon fiber. The foot of the U-shaped shape memory alloy fiber is semi-fixed on the polytetrafluoroethylene film composite cloth with a floating thread, and at the same time, a thermal insulation gasket is added to the corresponding position of the polytetrafluoroethylene film composite cloth.

Embodiment 2

[0028] Such as Figure 5 As shown, the basalt fiber / carbon fiber cloth of the fireproof outer layer 1, the shape memory alloy fiber of the heat insulation layer 2, the waterproof breathable layer 3, and the outlast acrylic fiber / cotton cloth of the comfort layer 4 are combined in sequence, and the U-shaped shape memory alloy fiber and The polytetrafluoroethylene film composite cloth is set between the basalt fiber / carbon fiber cloth and outlast acrylic fiber / cotton cloth layers. When the S-shaped shape memory alloy fiber is excited, fix the corresponding position of its peak to the corresponding position on the basalt fiber / carbon fiber cloth, which corresponds to the interweaving of carbon fiber; and fix the corresponding position of the wave trough to the outlast acrylic fiber / cotton cloth At the same time, add a thermal insulation gasket to the corresponding position of the polytetrafluoroethylene film composite cloth.

Abstract

The invention discloses an instantaneous high temperature resistant intelligent fire-resistant heat-insulating composite fabric structure. A vertical section of the composite fabric structure shows that from outside to inside, the composite fabric structure comprises orderly a fire-resistant outer layer, a heat insulating layer, a water-repellent and gas-permeable layer and a comfortable layer. The fire-resistant outer layer and the comfortable layer are sewn into a pipe structure and the heat insulating layer and the water-repellent and gas-permeable layer are wrapped in the pipe structure. Under a temperature excitation, the composite fabric can display a shape memory function, increase a fabric thickness and form an air layer so that a heat insulating performance is improved. The composite fabric has the advantages of reasonable structure, good flame retardancy, excellent thermal insulation performances, good water-repellent and gas-permeable performance, good comfortableness and good reusability of shape memory alloy fiber. Therefore, the composite fabric can be utilized for instantaneous high temperature resistant fire-resistant protective clothing.

Description

technical field [0001] The invention relates to a composite fabric structure, in particular to an instantaneous high temperature resistant intelligent fireproof and heat insulation composite fabric structure. Background technique [0002] In the research and development of firefighting clothing, it is always contradictory to enhance the thermal protection performance and reduce the metabolic heat load, both of which may cause injury or affect the health of firefighters. Good thermal protection can be obtained by wearing multiple layers or heavy clothing, but it will reduce the heat and moisture transfer performance and cause excessive physiological heat load, so that firefighters need more frequent and longer breaks during work to eliminate Fatigue and its own physiological heat load, which reduces efficiency. Therefore, the biggest defect of present firefighting suits is that they cannot realize good thermal insulation performance and comfort performance simultaneously. ...
