Fabric with enhanced flame retardant performance and preparation method thereof

Abstract

The invention discloses a fabric with enhanced flame retardant performance and a preparation method thereof. Both warp and weft of the fabric are blended yarns that are prepared from 70-80 weight percent of cellulose fiber and 20-30 weight percent of high-strength Vinylon fiber, wherein before blending, the high-strength Vinylon fiber is treated with a softening agent, and the fabric is prepared by processing the blended yarns into grey cloth, then singeing, scouring, bleaching, mercerizing, padding flame retardant liquor, pre-shaping, continuously fumigating with ammonia to tidy the fabric, oxidation rinsing, softening and shaping. Through adoption of the preparation method for the fabric with enhanced flame retardant performance, the fabric maintains the strength after flame retardant treatment, the preparation cost is low, the fabric can be produced efficiently in an environment-friendly way, and the treated fabric has better flame retardant performance.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a flame-retardant reinforced fabric and a preparation process thereof. Background technique [0002] Cellulose fiber fabrics are favored by people because of their good moisture absorption and air permeability, good skin-friendly properties, and comfortable wearing. However, due to the low limiting oxygen index of cellulose fiber, it is a flammable fiber and has a large combustion-supporting property, which limits the application range of cellulose fiber fabrics; fires caused by the burning of cellulose fiber-containing clothing also occur frequently. In order to protect people's lives and property safety, it is extremely necessary to endow cellulose fiber fabrics with flame retardant properties. [0003] At present, the methods for imparting flame-retardant properties to cellulose fibers mainly include the method of adding flame-retardant fibers and the method of f...

AI Technical Summary

Problems solved by technology

Phosphorus-based flame retardants are mainly based on CP method and PROBAN finishing method. The former has great damage to strength, poor flame retardant effect and durability, and has obvious defects; the latter has certain damage to fabric strength, and ammonia fumigation process A large amount of ammonia gas is emitted, and free formaldehyde is released, which has attracted great attention from relevant research institutes and manufacturers

[0005] Due to the disadvantage of high price in the preparation technology of flame-retardant fibers, and the effect of reducing the strength of phosphorus-based flame-retardant technology, how to control the cost under the premise of ensuring the flame-retardant effect, while ensuring the basic performance of the fabric, is the research and development and production need to consider main problem
