Abstract

The invention relates to fire-resistant cloth for resisting a temperature of 320-340 DEG C and a preparation method thereof, and belongs to the technical field of textile materials and fire prevention. Warp is prepared from, by mass, 30-70% of polyphosphamide fiber and 30-70% of aramid fiber, and weft is prepared from, by mass, 1-30% of long stapled cotton, 29-70% of polyphosphamide fiber and 29-70% of alginate fiber. The warp is formed by blending polyphosphamide fiber and aramid fiber, the weft is formed by blending long stapled cotton, polyphosphamide fiber and alginate fiber, and the warp and the weft are combined and woven into fire-resistant cloth with certain density through a staggered weaving method; after leaving a fire source, the cloth can automatically flame out without producing molten drops, the cloth is curled at the temperature of 352 DEG C and is carbonized at a high temperature without combusting, and the permanent effect is achieved. The fire-resistant cloth woven through the method has the advantages of being durable, resistant to high temperature, good in breathability, high in strength, good in hand feeling, good in dyeing and finishing performance, comfortable to wear and the like.

Description

technical field [0001] The invention relates to a 320-340°C fire-resistant cloth and a preparation method thereof, belonging to the technical field of textile materials and fire prevention. Background technique [0002] Various industries such as petrochemical, natural gas, public security, and fire protection require fabrics with flame-retardant and fire-resistant properties. At present, there are many kinds of flame-retardant and fire-resistant fabrics. DuPont Company of the United States was the first to use the copolymerization method to improve its thermal stability through the density and cohesion of the macromolecular chains of fiber-forming polymers, and successfully developed a product called " Nomex" aromatic polyamide fiber has very good heat resistance, and its limiting oxygen index is 29. Although its limiting oxygen index is not very high, it can extinguish itself without producing molten droplets after it leaves the fire source; Japan Teijin's "Terjinconex", ...
