[0050] Embodiment 2, preparation of high-strength flame-retardant anti-droplet anti-static fabric 2
[0051]1) 17% of aramid fiber (wherein the proportion of aramid 1414 fiber is 80%), 45% of flame-retardant viscose fiber (FR fiber provided by Lenzing Company of Austria) and organic conductive fiber (conductive fiber provided by China Textile Company of Japan) ) 3% mixed evenly, carding, drawing, secondary drawing, third drawing, roving, stand-by; wherein, the sliver speed during carding is 650m / min, and the sliver weight is 5g / m; The stripping speed is 200m / min, and the stripping weight is 7g / m.
[0052] 2) Anti-droplet treatment: pad the flame-retardant nylon filament into the pentaerythritol solution, the treatment temperature of the padding solution is 55°C, and the liquid-carrying amount of the flame-retardant fiber after the padding treatment is 200%; carry out electron beam irradiation According to the graft cross-linking reaction, the electron beam irradiation dose is...
Embodiment 3
[0054] Embodiment 3, preparation of high-strength flame-retardant anti-droplet anti-static fabric 3
[0055] 1) 16.5% of aramid fiber (of which aramid 1414 fiber is 100%), 50% of flame-retardant viscose fiber (FR fiber provided by Lenzing Company of Austria) and organic conductive fiber (conductive fiber provided by Japan China Textile Co., Ltd.) 2.5% mix evenly, carry out carding, drawing, secondary drawing, third drawing, roving, stand-by; Wherein, the sliver speed when carding is 600m / min, the sliver weight 6g / m; The speed is 230m / min, and the delivery weight is 6g / m.
[0056] 2) Anti-melt droplet treatment: pad the flame-retardant nylon filament into a dipropylene glycol solution, the treatment temperature of the padding solution is 70°C, and the liquid-carrying amount of the flame-retardant fiber after the padding treatment is 100%; Electron beam irradiation grafting cross-linking reaction, the electron beam irradiation dose is 300kGy, washed clean, finally combed into s...
