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

Abstract

The invention discloses a low-torque anti-arc composite fabric and a preparation method thereof, which sequentially includes a flame-retardant and heat-insulating layer, a flame-retardant adhesive connection layer and an antibacterial and heat-resistant layer from outside to inside, and is flame-retardant and heat-insulating in parts by weight. The layer mainly consists of 10-50 parts of Lenzing flame-retardant viscose, 20-40 parts of acrylic, 10-30 parts of aramid 1313, 5-15 parts of aramid 1414, 10-30 parts of polyimide and 1-3 The antibacterial and heat-resistant layer is mainly composed of 20-60 parts of silicon nitrogen flame-retardant viscose, 20-40 parts of acrylic fiber, 10-30 parts of polyarylene oxadiazole fiber, 10-30 parts of aramid 1313 It is blended with 1 to 3 parts of conductive fiber, and the twist of the antibacterial heat insulation layer is 60 to 65 twists per 10 cm. The low-torque anti-arc composite fabric obtained by compounding the multi-layer structure can have good anti-arc and anti-explosion performance on the outside, and has good softness, comfort and breathability on the inside.

Description

Technical field[0001]The present invention relates to the field of textile technology, and in particular, there is a low torque anti-arc composite fabric and a preparation method thereof.Background technique[0002]In some working places with flammable dust or gas or charged, when the combustible dust or gas constitutes a certain particular concentration in the combustion gas, there is a severe combustion, while generating a high temperature while producing a high temperature There is also a shock wave, which can generate double damage to the surrounding human body. Or when the current is discharged through certain insulating media (e.g., air), an arc can generate an arc. When the fault current is large, the arc can generate more than 10,000 degrees Celsius to a higher high temperature, and the high heat of the arc allows air to heat and generate high heat gas flow shock waves. .[0003]The above two cases can lead to serious burn in the staff, while wearing a power-saving shot can effe...

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.
