USE - Used as blended flame-retardant fabric containing graphene fiber. ADVANTAGE - The fabric: has good flame retardance, good antibacterial effect and comfort. DETAILED DESCRIPTION - Blended flame-retardant fabric containing graphene fiber comprises 20-30 pts. wt. graphene- polyacrylonitrile nanofiber, 20-30 pts. wt. rabbit hair fiber, 10-20 pts. wt. basalt fiber, 30-40 pts. wt. cotton fiber and 15-20 pts. wt. seaweed fiber. The pre-processing of the blended flame-retardant fabric containing graphene fibers comprises (1) pre-processing rabbit hair fiber and alginate fiber: opening treatment rabbit hair fiber and alginate fiber, adding lanolin and antistatic agent, uniformly spraying to the fiber to reduce the static, spraying after stewing for > 24 hours, (2) pre-processing of cotton fiber: placing the cotton fiber into sodium dodecyl sulfate aqueous solution before using, ultrasonic for 2 hours, washing with deionized water, using absolute ethyl alcohol, ultrasonic washing for 10-20 minutes, using deionized water washing and drying oven at 70℃ for 1 hours to obtain blank cotton fibers, taking thiourea and urea to dissolve into absolute ethyl alcohol, adding butyl titanate, using 5 wt.% nitric acid to adjust the pH value to 3-4, stirring uniformly, slowly dropping the deionized water into the solution and continuously stirring for 20-23 minutes, allowing to stand for 0.8-1 hours to obtain the wet gel, continuously stirring the sol solution obtained in the step (1), soaking the cotton fiber prepared in the step (1) into the sol solution for 5 -7 minutes after the Tyndall phenomenon appears and drying to obtain the pre-processing of cotton fiber, (3) pre-processing graphene- polyacrylonitrile nano fibers, basalt fibers, pre-processing cotton fibers, pre-processing rabbit hair fibers and pre-processing seaweed fibers into strips, spinning, fabric to obtain blended fabric and (4) blended fabric for flame-retardant finishing: using flame retardant, resin, softening agent and phosphoric acid, dipping and rolling, drying, baking, soda neutralizing, making the pH value 7-8, soaping, water washing and drying to obtain the flame-retardant fabric.
