Embodiment 1

[0028] Using meta-aramid fibers, para-aramid fibers and antistatic fibers to process a yarn number of 19.7tex flame-retardant antistatic yarns, of which: the weight percentage of meta-aramid fibers is 93%, and para-aramid fibers The weight percentage of the antistatic fiber is 5% and the weight percentage of the antistatic fiber is 2%, and the processing steps are as follows.

[0029] A). Preparation of mixed fiber, the specification of 94.9% by weight is the meta-aramid fiber of 2.5D × 51mm and the specification of 5.1% by weight is the para-aramid fiber of 1.5D × 51mm for the spinning industry The usual cotton blending machine is used to mix the meta-aramid fiber and the para-aramid fiber while spraying the antistatic emulsion. The antistatic emulsion is obtained by dissolving the antistatic agent in water. The antistatic agent The concentration in water is 3.5%, that is, every 100g of water contains 3.5g antistatic agent, and the spraying amount of antistatic emulsion is 2....

Embodiment 2

[0038] Change the weight percent of meta-aramid fiber to 70%, change the weight percent of para-aramid fiber to 26%, change the weight percent of organic antistatic fiber to 4%, and change the number of flame-retardant antistatic yarn to It is 16.4tex.

[0039] Only change the percentage by weight of the meta-aramid fiber in step A) into 72.9%, change the percentage by weight of the para-aramid fiber into 27.1%, and change the concentration of antistatic agent in water into 2.5%; An antistatic fiber strip and seven aramid mixed fiber pre-drawings are merged to make an antistatic fiber pre-mixed strip containing 0.58 grams of antistatic fiber per meter, and then 6 aramid mixed fiber pre-drawings are combined with 2 antistatic fiber premixed strips are mixed; in step F), only the total draft ratio, jaw gap, traveler type and twist of the compact spinning machine are changed, so that the dry weight is 1.56g / 100m, and the twist is 1.56g / 100m. It is a blended compact yarn with 85 ...

Embodiment 3

[0041] Change the weight percentage of meta-aramid fiber to 85%, the weight percentage of para-aramid fiber to 13.5%, change the weight percentage of organic antistatic fiber to 1.5%, and the yarn number of flame-retardant antistatic yarn Change the number to 24.6tex.

[0042] Only change the percentage by weight of the meta-aramid fiber in step A) into 86.3%, change the percentage by weight of para-aramid fiber into 13.7%, and change the concentration of antistatic agent in water into 2.8%; 1 antistatic fiber strip and 7 aramid blended fiber pre-drawings are combined to make antistatic fiber premixed strips containing 0.45 grams of antistatic fiber per meter; change the total traction of the compact spinning machine in step F) Elongation, jaw gap and traveler type and twist, so as to obtain dry basis weight is 2.34g / 100m, twist is the blended compact yarn of 70 twists / 10cm; Change the vacuum in step G) to be-0.06Mpa, temperature 90 ℃ and holding time is 115min. All the othe...

Abstract

The invention relates to retardant anti-static yarn and a processing method thereof, which belongs to the technical field of spinning. The yarn is composed of the following materials by the weight percentage: 70 percent to 95 percent of meta aramid fiber, 3 percent to 28 percent of para aramid fiber and 1.5 percent to 4 percent of anti-static fiber. The afterflame time of the retardant anti-static yarn obtained by the disclosed technical proposal is short (shorter than 4S), the damage length is less than 100mm, the wear resistance level is higher than or equal to 3.5, and the mass specific resistance is less than 7.4*10<10>; because of the meta aramid fiber, the para aramid fiber and the anti-static fiber, the retardant and anti-static effect are permanent and do not fade; the recommended process requirements are not harsh and can ensure the technical effect of the retardant anti-static yarn.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a flame-retardant and antistatic yarn, and also relates to a processing method of the flame-retardant and antistatic yarn. Background technique [0002] Clothes made of flame-retardant fabrics are widely used in aerospace, military, fire protection, petrochemical, electrical, gas, mechanical metallurgy and other fields, and the basis of flame-retardant fabrics is undoubtedly flame-retardant yarns. The raw materials used to process flame-retardant yarn mainly include the following two types, one is the conventional synthetic fiber with surface flame-retardant treatment such as polyester fiber, nylon fiber or polyester-nylon composite fiber, or the regenerated fiber with surface flame-retardant treatment such as viscose Fiber, etc.; the second is to use meta-aramid fiber. The processing method of the yarn is through opening and cleaning, carding, drawing, roving, spin...
