Coal mine protective clothing fabric and preparation method thereof

Abstract

The invention provides a coal mine protective clothing fabric which is durable and comfortable to wear, flame-retardant, anti-static, oil-proof, waterproof, good in antifouling performance and low in price. The coal mine protective clothing fabric is prepared from warp yarns and weft yarns by embedding a PET100D conductive filament every 2cm in the warp direction, wherein each warp yarn is a vortex spinning all-cotton MVS CM18.2texX2 two-fold yarn, each weft yarn is a vortex spinning all-cotton MVS CM32.4tex single yarn, warp density is 421 pieces / 10cm, and weft density is 240 pieces / 10cm. The preparation method of the coal mine protective clothing fabric includes the steps: a, spinning; b, weaving including warping, sizing and drafting; c, printing and dyeing; and d, afterfinish including flame-retardant finish and tri-proof finish, wherein during flame-retardant finish, Pyrovatex CP new serves as fire retardant, and RUCOSTAR EEE serves as tri-proof finish agent.

Description

technical field [0001] The invention relates to clothing fabrics, in particular to a coal mine protective clothing fabric and a preparation method thereof. Background technique [0002] Most of the existing domestic coal mine protective fabrics are made of cotton. The warp yarn is generally C27.8tex×2, the weft yarn is C58.3tex, the warp density is 276 threads / 10cm, and the weft density is 165 threads / 10cm. The fabric feels rough and hard , Thick and heavy, with poor vapor and moisture permeability, if you exercise a little bit underground, you will sweat profusely and have poor comfort. At the same time, the existing protective clothing was tested and found that it is easy to burn when it encounters fire, and it can continue to burn when it leaves the flame. It has no flame-retardant function. Once a fire occurs underground, the consequences will be very serious.

AI Technical Summary

Problems solved by technology

[0002] Most of the existing domestic coal mine protective fabrics are made of cotton. The warp yarn is generally C27.8tex×2, the weft yarn is C58.3tex, the warp density is 276 threads / 10cm, and the weft density is 165 threads / 10cm. The fabric feels rough and hard , Thick and heavy, with poor vapor and moisture permeability. If you exercise a lot underground, you will sweat profusely and have poor comfort.

At the same time, the existing protective clothing is tested and found that it is easy to burn when it encounters fire, and it can continue to burn when it leaves the flame. It has no flame-retardant function. Once a fire occurs underground, the consequences will be very serious.

[0003] At present, the common problems of work clothes commonly used in coal mines are poor fabric quality, insufficient tensile strength and tear strength, and poor wear resistance. After washing, work clothes are quite worn on the edges such as necklines, cuffs, pockets, etc.; flame retardant properties Poor. Coal mine work clothes made of pure cotton are used throughout the country. Cotton fibers are combustible fibers without any flame-retardant finishing. The limiting oxygen index LOI is between 17 and 19, which is far lower than the minimum value of 27 that can be self-extinguished in the air. , not only has a fast burning speed, but also has a great combustion-supporting property; the anti-static property is poor, for the textiles worn by the human body, the fabric with static electricity often has a discharge phenomenon, and explosions and fire accidents are prone to occur in flammable and explosive occasions; no Waterproof, oil-proof, and anti-fouling (three-proof) functions, clothes are very easy to get wet and dirty

[0004] Foreign coal mine protective clothing usually uses meta-aramid, polyamide-imide (Kermel) and other fibers as the main raw material, which can achieve an ideal flame-retardant effect, and the fiber strength is high, and the clothes are durable, but The price of the above-mentioned fibers is more than 200,000 yuan per ton, the cost of garments is high, the dyeing performance of some fibers is poor, and the production process is complicated, which cannot be recognized by textile printing and dyeing enterprises and coal mining enterprises
