Embodiment 1

[0041] Add bishydroxyethyl terephthalate into the esterification reaction tank, keep the temperature at 250°C and the pressure at 1.2×10 5 Pa, 8.25 kg of high-purity terephthalic acid and 3.54 kg of ethylene glycol slurry were gradually added to the esterification reaction layer within 4 hours, and then the esterification reaction was carried out for 1 hour. Finally, 10.2 kg was taken from the obtained esterification reaction product and added to the polycondensation reaction layer.

[0042] The esterification reaction product was kept at 250° C. under normal pressure, and 2-methyl-1,3 propanediol was added in an amount corresponding to 10 mol% of all diols in the obtained polyester and stirred for 30 minutes. Then add phosphoric acid with an atomic weight of phosphorus equivalent to 18 ppm of the polymer, 5 minutes later add antimony trioxide with an atomic weight of antimony equivalent to 230 ppm of the polymer, and cobalt acetate with an atomic weight of cobalt equivalent t...

Embodiment 2

[0050] The chips obtained in Example 1 were dried to keep the moisture content at 50 ppm, then melt-spun at a spinning temperature of 280° C., coiled at a pulling speed of 3000 m to obtain pre-oriented filaments with a circular cross-section, and then processed into untwisted 73D-36-DTY.

[0051] The warp and weft yarns are formed from the above-mentioned 73D-36-DTY and 75D-38-DTY conductive yarns with a twist of 250T / m, wherein the conductive yarns of 75D-38-DTY are made of ordinary yarns and non-dust-generating Conductive fibers are formed by composite processing of carbon fibers, and the conductive yarns are distributed in a grid pattern in the warp direction with a distribution interval of 4 mm. Perform fabric weaving. The finished product weave is plain weave, the density is 158*90 / inch, and the tightness is 2997.

[0052] The fabric obtained above is subjected to scouring, pre-drying, intermediate setting, dyeing, post-drying, and post-finishing setting. The dyeing te...

Embodiment 3

[0055] Dry the slices prepared in Example 1 to keep the moisture content at 50ppm, and then melt-spin them at a spinning temperature of 290°C to make pre-oriented yarns with "cross" and circular cross-sections respectively, and then process them separately Untwisted 75D-36-FDY and 100D-36-DTY were made.

[0056] The warp yarn is formed by the above-mentioned 75D-36-FDY and the conductive yarn of 75D-38-DTY with a twist of 250T / m. The fibers are formed by composite processing of carbon fibers, and the conductive yarns are distributed in strips in the warp direction with a distribution interval of 6 mm.

[0057] Weft yarn selects 100D-36-DTY for use, carries out fabric weaving with above-mentioned warp yarn. The finished product weave is plain weave, the density is 202*82 / inch, and the tightness is 2888.

[0058] The fabric obtained above is subjected to scouring, pre-drying, intermediate setting, dyeing, post-drying, and post-finishing setting. The dyeing temperature is 95°C...

Abstract

The invention discloses a dustproof fabric capable of being dyed at normal pressure, which comprises non-fume-diffusion copolyester fibers containing a 2-methyl-1,3-propylene glycol structure and non-fume-diffusion conductive fibers, wherein the conductive fibers are distributed in a strip shape or a grid shape in the fabric, and the compactness of the fabric is 2000 to 4000. The dustproof fabric has excellent dustproof performance, better antistatic property and higher air permeability. The manufacturing process of the traditional dustproof fabric is simplified, the fabric can be dyed at normal pressure, and the production cost is reduced. The obtained dustproof fabric is light, thin and permeable, is comfortable to wear, is convenient for wearers to work flexibly, and is applicable to dustproof clothing of industries of semiconductors, foods, medicines and the like.

Description

technical field [0001] The present invention relates to a fabric. Specifically relates to a dust-proof fabric dyeable under normal temperature and normal pressure. Background technique [0002] With the rapid development of economy and society, industrial clean rooms and biological clean rooms are more and more widely used in semiconductors, optical instruments, precision electronic instruments and special surgery wards, food, brewing and other industries that require a clean working environment. Human activities and clothing are important sources of dust in cleanrooms. Although fabrics with good dust-proof performance can effectively prevent human body secretions and dust in underwear from being discharged to the environment, and at the same time prevent clothing from absorbing external dust and do not produce lint itself, thereby ensuring the cleanliness of the working environment, but currently Some dustproof fabrics need to be dyed and processed at high temperature, th...
