Embodiment 1
[0039] Example 1. Preparation of flame-retardant anti-melt dripping anti-static fabric 1
[0040] 1) The first step of fiber mixing: 20% aramid fiber (of which aramid 1414 fiber accounts for 60%), flame-retardant viscose fiber (FR fiber provided by Austrian Lenzing Company) 53% and organic conductive fiber (Nakabo, Japan) Conductive fiber provided by the company) 2% mixed evenly for use;
[0041] 2) The second step of mixing nylon filaments: Combine 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. Mix the strips evenly and set aside;
[0042] 3) Spinning in the third step: carding, drawing, second drawing, tertiary drawing, roving of the mixed fiber, and then mixing with the nylon filament in the second step for core spinning spun yarn; Process to obtain the blended core-spun yarn used for combat fabrics, and then weave. Among them, th...
Embodiment 2
[0043] Example 2. Preparation of flame-retardant anti-melt dripping anti-static fabric 2
[0044] 1) The first step of fiber mixing: 17% aramid fiber (of which aramid 1414 fiber accounts for 80%), flame-retardant viscose fiber (FR fiber provided by Austrian Lenzing Company) 61% and organic conductive fiber (Nakabo Conductive fiber provided by the company) 1% mixed evenly for use;
[0045] 2) The second step of mixing nylon filaments: mix the flame-retardant nylon 66 filament with a phosphorus content of 6000ppm and a strength of 3.5cN / dtex at 18% and a high-strength non-flame retardant nylon 66 filament with a strength of 8cN / dtex at 3%. Draw and mix evenly for use;
[0046] 3) Spinning in the third step: carding, drawing, second drawing, tertiary drawing, roving of the mixed fiber, and then mixing with the nylon filament in the second step for core spinning spun yarn; Process to obtain the blended core-spun yarn used for combat fabrics, and then weave. Among them, the delivery sp...
Embodiment 3
[0047] Example 3. Preparation of flame-retardant anti-melt dripping anti-static fabric 3
[0048] 1) The first step of fiber mixing: 18% aramid fiber (of which aramid 1414 fiber accounts for 100%), flame-retardant viscose fiber (FR fiber provided by Austrian Lenzing Company) 61% and organic conductive fiber (Nakabo Conductive fiber provided by the company) 1% mixed evenly for use;
[0049] 2) The second step of mixing nylon filaments: Combine 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. Mix the strips evenly and set aside;
[0050] 3) Spinning in the third step: carding, drawing, second drawing, tertiary drawing, roving of the mixed fiber, and then mixing with the nylon filament in the second step for core spinning spun yarn; Process to obtain the blended core-spun yarn used for combat fabrics, and then weave. Among them, the deli...
