Embodiment 1
[0039] Embodiment 1, preparation of flame-retardant anti-droplet anti-static fabric 1
[0040] 1) Fiber mixing in the first step: 20% of aramid fiber (of which aramid 1414 fiber accounts for 60%), 53% of flame-retardant viscose fiber (FR fiber provided by Lenzing Company in Austria) and organic conductive fiber (Japan China Textile Co., Ltd. Conductive fiber provided by the company) 2% mixed evenly for use;
[0041] 2) Mixing of nylon filaments in the second step: 25% of flame-retardant nylon 66 filaments with a phosphorus content of 4000ppm and a strength of 5cN / dtex and 2% of high-strength non-flame-retardant nylon 6 filaments with a strength of 7cN / dtex are mixed mix well and set aside;
[0042] 3) The third step of spinning: carding, drawing, secondary drawing, third drawing, and roving of the uniformly mixed fibers, and then performing core-spun spun yarn with the nylon filaments uniformly mixed in the second step; process, to obtain the blended core-spun yarn used in c...
Embodiment 2
[0043] Embodiment 2, the preparation of flame-retardant anti-droplet anti-static fabric 2
[0044] 1) The first step of fiber mixing: 17% of aramid fiber (of which aramid 1414 fiber accounts for 80%), 61% of flame-retardant viscose fiber (FR fiber provided by Lenzing Company in Austria) and organic conductive fiber (Japan China Textile Co., Ltd. Conductive fiber provided by the company) 1% mixed evenly for use;
[0045] 2) The second step of nylon filament mixing: 18% of flame-retardant nylon 66 filament with a phosphorus content of 6000ppm and a strength of 3.5cN / dtex and 3% of high-strength non-flame-retardant nylon 66 filament with a strength of 8cN / dtex Draw and mix evenly for later use;
[0046] 3) The third step of spinning: carding, drawing, secondary drawing, third drawing, and roving of the uniformly mixed fibers, and then performing core-spun spun yarn with the nylon filaments uniformly mixed in the second step; process, to obtain the blended core-spun yarn used in...
Embodiment 3
[0047] Embodiment 3, preparation of flame-retardant anti-droplet anti-static fabric 3
[0048] 1) Fiber mixing in the first step: 18% of aramid fiber (of which aramid 1414 fiber accounts for 100%), 61% of flame-retardant viscose fiber (FR fiber provided by Lenzing Company in Austria) and organic conductive fiber (Japan China Textile Co., Ltd. Conductive fiber provided by the company) 1% mixed evenly for use;
[0049] 2) Mixing of nylon filaments in the second step: 18% of flame-retardant nylon 66 filaments with a phosphorus content of 4500ppm and a strength of 4cN / dtex and 2% of high-strength non-flame-retardant nylon 66 filaments with a strength of 8cN / dtex are combined mix well and set aside;
[0050] 3) The third step of spinning: carding, drawing, secondary drawing, third drawing, and roving of the uniformly mixed fibers, and then performing core-spun spun yarn with the nylon filaments uniformly mixed in the second step; process, to obtain the blended core-spun yarn used i...
