Low-torque arc-proof composite fabric and preparation method thereof

Abstract

The invention discloses a low-torque arc-proof composite fabric and a preparation method thereof. The composite fabric sequentially comprises a flame-retardant heat-insulating layer, a flame-retardantadhesive connecting layer and an antibacterial heat-resistant layer from outside to inside, wherein the flame-retardant heat-insulating layer mainly comprises, by weight, the following components: 10-50 parts of blue essence flame-retardant adhesive, 20-40 parts of vinylon, 10-30 parts of aramid fiber 1313, 5-15 parts of aramid fiber1414, 10-30 parts of polyimide and 1-3 parts of conductive fiber, the antibacterial heat-resistant layer is mainly formed by blending 20-60 parts of silicon-nitrogen flame-retardant adhesive, 20-40 parts of vinylon, 10-30 parts of polyaryloxy diazole fiber, 10-30parts of aramid fiber1313 and 1-3 parts of conductive fiber, the yarn twist degree of the antibacterial heat-resistant layer is 60-65 twist / 10 cm. The low-torque arc-proof composite fabric obtained bycompounding a plurality layers of structures has good arc-proof and anti-explosion performances to the outside and good soft comfort and air permeability to the inside under the condition of being light and thin.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a low-torque anti-arc composite fabric and a preparation method thereof. Background technique [0002] In some workplaces with combustible dust or gas or charged electricity, when the composition of combustible dust or gas in the combustion-supporting gas reaches a certain concentration and has enough ignition energy, violent combustion will occur, while generating high temperature Shock waves are also generated, which can cause double damage to surrounding humans. Or when the current discharges through some insulating medium (such as air), an arc can be generated. When the fault current is large, the arc can generate a high temperature exceeding 10,000 degrees Celsius. . [0003] Both of the above situations may cause serious burns to the staff, and wearing arc-proof clothing can effectively reduce the damage to the human body caused by high-temperature shock waves caused by ...

AI Technical Summary

Problems solved by technology

Therefore, the arc protection fabric should not only block the conduction of heat, but also keep it from breaking under the action of high temperature, otherwise the heat flow will directly act on the human body, which will cause serious burns

Existing arc protection fabrics are usually thick and heavy, with poor comfort and breathability. The higher thickness is used to obtain effective protection performance. Therefore, the interior of arc protection clothing made of heavy fabrics is stuffy, and the arc protection clothing is stiff and inconvenient to move around.
