Abstract: A flame-retardant fabric was developed by blending para-aramid fiber with flame-retardant Modal fiber, which has solved the problems of thermal shrinkage and cracking in fire of the flame-retardant fabric. With the characteristics of high strength, high hygroscopicity, high heat resistance and low price, this fabric has broad prospects in the field of thermal protective garment. This paper introduces the difficulties in the spinning and weaving process and related solutions. And the experimental results show that this blended fabric has excellent performance.

Key words: para-aramid fiber; flame-retardant Modal fiber; blended fabric; development
