Problems solved by technology

At present, the research on aramid fabrics in the field of firefighters' protective clothing is mainly to coat the surface of aramid fabrics with a fireproof adhesive layer or to laminate aramid fabrics with aluminum foil layers or glass fibers to achieve high temperature resistance and fire prevention. However, the adhesive layer coated on the surface of the aramid fabric is easy to fall off after long-term use; in addition, although the aramid fabric has certain high temperature resistance and comfort, when it is used as a protective clothing base fabric, its air permeability is of great importance to the whole The breathability of protective clothing is extremely critical, because once the aramid fabric has poor breathability, the sweat emitted by firefighters during the battle will be blocked. Wet feeling will seriously affect the combat efficiency of firefighters

Abstract

The invention relates to waterproof and oil-proof flame-retardant breathable aramid fabric and a preparation method thereof, and belongs to the technical field of textile fabric. The preparation method of the waterproof and oil-proof flame-retardant breathable aramid fabric comprises the following steps: sequentially carrying out pretreatment, softening finishing, primary drying, padding finishing, secondary drying, washing and ternary drying on the aramid fabric, so as to obtain the waterproof and oil-proof flame-retardant breathable aramid fabric. The waterproof and oil-proof flame-retardant breathable aramid fabric has good water and oil repellency and good pollution resistance; and furthermore, the waterproof and oil-proof flame-retardant breathable aramid fabric not only has excellent breathability and comfort, but also has excellent adhesiveness on various fireproof coatings.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a waterproof, oil-proof, flame-retardant and breathable aramid fabric and a manufacturing method thereof. Background technique [0002] Aramid, namely m-phenylene terephthalamide, has excellent properties and is widely used in the field of composite materials and protective clothing. It has ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, Insulation, anti-aging and other excellent properties. Its strength is 5 to 6 times that of steel wire, its modulus is 2 to 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is only about 1 / 5 of that of steel wire. It does not decompose at a temperature of 560 degrees. Does not melt. [0003] In recent years, due to its excellent performance, aramid fiber fabrics have been widely used in the field of firefighter pro...
