Abstract

The invention relates to a high-flame-retardant breathable protective fabric and a preparation method thereof, and belongs to the technical field of textile fabrics. The high-flame-retardant breathable fabric comprises base cloth and a flame-retardant layer bonded to the surface of the base cloth, and the base cloth is formed by weaving modified ramie fibers and polyester fibers. Firstly, modified ramie fibers with good air permeability are selected as main fibers, the air permeability and heat dissipation performance of the base cloth are guaranteed, the ramie fibers are modified, and the elasticity, cohesion and spinnability of the ramie fibers are improved; secondly, in order to ensure the air permeability of the base cloth, the outer layer of the base cloth is subjected to single-side modification, and a flame-retardant layer is grafted on the outer layer of the base cloth; thirdly, the flame-retardant layer is subjected to single-side modification, so that the bonding performance between the flame-retardant layer and the base cloth is improved; and finally, the flame-retardant layer contains a flame retardant, the flame-retardant property is excellent, and the flame retardant contains a fluorine-containing branched chain, so that the flame-retardant layer is endowed with high flame-retardant property, water resistance and chemical reagent resistance.

Description

technical field [0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a high flame-retardant breathable protective fabric and a preparation method thereof. Background technique [0002] Ordinary chemical fibers, synthetic fibers and natural fibers are relatively easy to burn. In high-temperature industries such as firefighting and smelting, strong radiant heat can make ordinary clothing rapidly melt, decompose and burn, which can easily burn the skin of operators and threaten their lives. Due to the addition of flame retardant fibers in the fabric or the coating of flame retardants on the fabric, the flame retardant clothing can greatly slow down the burning speed, extinguish itself immediately after moving, and the burning part is quickly carbonized without melting or dripping Or piercing, giving people time to evacuate the burning scene or take off the burning clothes, reduce or avoid burns and scalds, and achieve the purpose ...
