Description
Technical field
The present invention relates to garment material, specifically, is that a kind of coal mine protective takes fabric and preparation method thereof.
Background technology
Domestic existing coal mine protective fabric composition great majority are cotton, warp thread is generally selected C27.8tex * 2, weft yarn is selected C58.3tex, warp-wise density is 276/10cm, and latitudinal density is 165/10cm, fabric wiriness, thick and heavy, water vapor permeability can be poor, slightly large at the down-hole amount of exercise, will be soaked with sweat, comfort level is relatively poor.Simultaneously detect discovery for existing protective clothing, meet fiery easy firing, leave flame energy afterflame, do not have anti-flaming function, in case the condition of a fire occurs in the down-hole, consequence will be very serious.
At present the colliery ubiquitous problem of Work Clothes commonly used is that fabric quality is poor, and TENSILE STRENGTH, tearing strength are inadequate, and ABRASION RESISTANCE is also relatively poor, and is quite severe in the wearing and tearing of the marginal portions such as neckline, cuff, pocket through the Work Clothes after the washing; Fire resistance is poor, and the colliery Work Clothes of pure-cotton fabric is all used in the whole nation, and cotton fiber is combustible fibre, through any anti-flammability arrangement, limited oxygen index LOI is not between 17～19, far below the minimum of a value 27 that can certainly put out in the air, not only burning velocity is fast, and has very large combustion-supporting property; Static electricity resistance is poor, and for the textiles of human body dress, the fabric of static electrification often has electric discharge phenomena, blasts easily and fire incident in inflammable and explosive occasion; Without waterproof, grease proofing, antifouling (three is anti-) function, clothes is very easily moist and dirty.
External coal mine protective clothes adopt the fibers such as meta-aramid, fragrant sulfone synthetic fibre, polyamide-imides (Kermel) as body material usually, can play desirable flame retardant effect, and fibre strength is high, clothes is solid endurable, but above-mentioned several fiber price per ton is all more than 200,000 yuan, the ready-made clothes cost is high, and the part fiber dyeing performance is poor, production process route is complicated, can not obtain the approval of textile printing and dyeing enterprises and coal mining enterprise.
Summary of the invention
The purpose of this invention is to provide a kind of durable, comfortable, fire-retardant, antistatic, grease proofing, waterproof, antifouling property coal mine protective good, that price is low worn and take fabric.
This coal mine protective takes fabric, warp thread is vortex spinning cotton MVS CM18.2tex * 2 doublet cords, and weft yarn is vortex spinning cotton MVS CM32.4tex single thread, through close be 421/10cm, filling density is 240/10cm, and warp-wise embeds a PET100D electrically conductive filament every 2cm.
Beneficial effect of the present invention: colliery operating personnel's protective clothing must possess good durability, can bear repeatedly and rub, pull and wash, so the seam strength of the intensity of garment material, ABRASION RESISTANCE, morphological stability, clothes processing etc. all is very important factor.This fabric warp thread is selected MVS CM18.2tex * 2, and the brute force of doublet cord and ABRASION RESISTANCE are all far above single thread, and the durability of fabric also can correspondingly strengthen; Weft yarn is selected MVS CM32.4tex.The moisture pick-up properties of purified cotton yarns is better, cooperate the special core structure of vortex spinning yarn the moisture content that yarn absorbs can be derived rapidly, the sweat that coal miner produces during operation under mine is absorbed very soon and the sandwich layer by yarn distributes, and snugness of fit improves greatly.
The cotton clothes can not substitute antistatic clothing, because cotton textiles itself also are insulators, when relative humidity was lower than 30%, the carried charge of pure cotton cloth was sometimes also greater than chemical fabric.When only having relative humidity to be higher than 50%, because the cotton textiles suction does not just play static, although in humidity higher area or place, also can play the effect of certain antistatic, but the down-hole natural conditions are complicated, humidity is not identical yet, and such as the mine in the north or when winter, weather was dry, potential safety hazard has been buried in the use of pure-cotton fabric undoubtedly.Therefore, adding electrically conductive filament in cotton coal mine protective clothes is very important.
Material also constantly neutralizes when electric charge constantly produces in friction process, and corona discharge and charge leakage are two kinds of Neutralizing modes.Corona discharge is that conductive fiber in the fabric is under the effect of electrostatic field, make ambient air generation ionization and form negative ions, a kind of and fabric in the negative ions with mutually on the contrary neutralization of electrostatic charge, another kind then with the neutralization of environment electric charge the earth, thereby eliminated static.And the mainly volume conduction by rubber self of charge leakage, surface conductive and the three approach such as radiation in the air, wherein surface conductive is main, this is because the volume conduction depends primarily on the volume coefficient of conductivity, surface conductive depends primarily on surface resistivity, improve its surface electrical conduction thereby manage to reduce its sheet resistance, just can play the effect that prevents static.This project is intended embedding the good electrically conductive filament of conducting function when face weave, makes that institute's static electrification neutralizes by corona discharge on the fabric, thereby effectively prevents the fire that causes because of static.
When fire damp concentration is higher, can set off an explosion such as spark.Textile Work Clothes can prevent the clothes accumulation of static electricity in the higher situation of ambient humidity, in order to guarantee also possess good antistatic behaviour in the less situation of humidity, colliery operating personnel's protective clothing can adopt the pure-cotton fabric through antistatic design processing.It is antistatic that the present invention adopts the method for adding conductive fiber in fabric, and it has effective, does not affect fabric style, the advantage of consistency of performance.Use conductive fiber so that textile material is antistatic, its antistatic mechanism is because conductive fiber can produce a kind of very corona discharge of mitigation, when electrostatic pressure reach must numerical value after, namely produce nonarcing corona discharge, make the static elimination.This phenomenon is commonly referred to be conductive fiber in the fabric under the effect of electrostatic field, make ambient air generation ionization and form negative ions, a kind of and fabric in the negative ions with mutually on the contrary neutralization of electrostatic charge, another kind then with the neutralization of environment electric charge the earth, thereby eliminated static.The remarkable difference of corona discharge and electrostatic leakage is that corona discharge also can well be eliminated the static on the fabric in earth-free situation, and electrostatic leakage then needs kiss the earth or static is eliminated.
Therefore, the present invention is that a kind of durable, comfortable, fire-retardant, antistatic, grease proofing, waterproof, antifouling property coal mine protective good, that price is low can worn takes fabric.

Four, technological parameter and technology
One), spinning process
In clear comb connection operation, in order to guarantee the uniform continuity of yarn qualities, adopt many shipping marks in the process of distributing cotton, because shipping mark is more, for making the abundant shredding of cotton fiber and mixing, grabs and adopt " duty is grabbed and grabbed less the meticulous cotton that grabs " method in the cotton process; According to mic value, short flannel and the impurity content of raw cotton, when cotton cleaning process, use rational Beater Speed and dirt rod to space simultaneously.By the cotton knot in the sheet cotton AFIS data, short flannel impurity content, have stress further carry out combing, removal of impurities at carding process.
In mixing in doubling step, take the technique of " in quantitatively, heavily pressurization is spaced greatly, falls drawing-off, reasonable tension draft is fully and close, anti-tangle anti-blocking ", suitably amplify horn mouth production is carried out smoothly, it is flat to improve ripe rule solid carbon dioxide.Secondly adopt draft process, cotton fiber in sliver, reach fine stretch parallel and two road irregularities little, reduce yarn unevenness.
In combing process, in order to remove short flannel, cotton knot, the impurity in the cotton layer, reduce simultaneously the short flannel that combing processing itself produces, adopt the technique of " many combs are few to be beaten, fall more ", suitably reduce each hired roughneck's speed, reduce striking point.
The vortex spinning operation, process using booth high draft; The relative chemical fibre of cotton fiber length shorter, roller grip apart between floating fiber more; In the spinning process, sliver is very easily siphoned away by negative pressure, causes resultant yarn weight to change, and number variation occurs; Need increase the test period, better monitoring for this reason.
The reciprocal griping cotton machine of FA009 is according to quality requirement and rear road demand, and its hired roughneck's rotating speed is 1000r/min; The Beater Speed of FA105 Single axial waste silk opener is 500r/min; FA116 master's de-burring machine main frame speed is 400r/min; The licker-in speed of FA203B carding machine is 800r/min, and cylinder speed is 400r/min, and sliver exporting speed is 120m/min; 6 of the pre-parallel operation number of doubling of FA306A, 1.8 times of back area drafts; JSFA288 combing machine linters rate is 18%; The FA306A drawing frame 4 * 9mm that spaces, head and 8 also close back area draft 1.8, and end and 6 also close back area draft 1.2; The roller gauge of NO.861 vortex spinning: MVS18.2tex: 37 * 39mm draws yarn speed: 380m/min; The roller gauge of MVS32.4tex: 37 * 39mm draws yarn speed: 380m/min.
Two), weaving process parameter
For making this fabric have anti-static function, we have added electrically conductive filament at the warp-wise of fabric, weave engineering two warp systems have also just been arranged, two kinds of different warp thread are arranged: a kind of MVS of being CM18.2tex * 2 doublet cords, another kind is the PET100D electrically conductive filament, two kinds of warp thread thicknesses differ larger, warping process how to make tension in Warping all even warp beam to reel smooth be crucial.MVS CM18.2tex * 2 doublet cord total quantity of warps are many, need share on 10 warp beams of reeling, and tension in Warping is wanted grasp bigger than normal.The PET100D electrically conductive filament only has 79 in the view picture fabric, cannot be whole on a warp beam separately, the PET100D long filament should be divided equally as far as possible wherein on 5 warp beams, distance on every warp beam between the adjacent filament keeps identical, for guaranteeing that warp beam is smooth and unwinding tension is even, PET100D long filament tension in Warping is wanted grasp less than normal, and drum pressure suitably strengthens.
The sizing operation is when putting warp beam, 5 warp beams that are wound with the PET100D long filament to be placed on rear one group of creel, doing the district when merging through the warp thread of two stock tanks like this, the yarn sheet of PET100D conductive filament just can place the upper strata, will put twisted wire during the sizing doff with two kinds of warp thread separately.Slashing technique prescription and knitting technology parameter are also very important, two kinds of warp thread of this fabric, and composition is different, and the sizing prescription is completely different, therefore will make overall plans.MVS CM18.2tex * 2 doublet cords are whole cotton threads, and when take starch slurry as main, the rate of sizing should not be too high, and the sizing purpose focuses on to be increased wear resistance and suitably increase powerful; PET100D conductive filament main body composition is terylene, and the brute force of long filament can satisfy woven demand, and the sizing purpose focuses on the convergence of strengthening long filament, when take chemical pulp as main.We are decided to be 7:3 with the ratio of starch and chemical pulp in the sizing prescription for above-mentioned situation, substantially can guarantee the sizing quality of two kinds of yarns.The stock tank slurry viscosity is middle low viscosity, and squeezing roller pressure is moderate, and the sizing speed of a motor vehicle should not be too fast.
The operation of gaiting will be combined folder to two kinds of yarns with two respectively and clamp before beam of a loom is pushed to the frame of gaiting, and the PET100D conductive filament is placed the front row, and MVS CM18.2tex * 2 place rear row, mainly are for the worker's operation of conveniently gaiting.The worker that gaits will wear first 84 MVS CM18.2tex * 2, and the order of gaiting is 1,2,3,4, wears a PET100D conductive filament again, is through the 5th page to sum up, so just can guarantee that the conductive filament interval equates.
The key point of weaving process is the input of pegging plan.Front four pages is 3/1 tissue, and the 5th page is 1/3 tissue, and ability and two kinds of yarn correspondences weave the style of design like this.The loom opening time is postponed, and regulates through the position line and opening amount, so that the shed open opening or cleaning.Calibrate main and auxiliary nozzle angle, in time change the problem nozzle, guarantee that air-jet weft insertion is smooth and easy.
