Description

A kind of fire-resistant antistatic jean and preparation method thereof
Technical field
The invention belongs to technical field of textile fabric, be specifically related to a kind of fire-resistant antistatic jean, the invention still further relates to the preparation method of this fire-resistant antistatic jean.
Background technology
Cotton fiber is natural fiber, its moisture pick-up properties is good, cotton fiber goods good permeability, comfortable and easy to wear, soft and warming, therefore cotton fiber has become the primary raw material of caused by spinning industrial production, but when the volume of perspiration of people is slightly large, cotton fiber can because of moisture expantion, its fortune declines and is pasted onto on skin, meanwhile, moisture content divergence speed is also comparatively slow, thus causes a kind of cold wet sense to human body.
Terylene is hydrophobic synthetic fibre, its moisture pick-up properties is low, ratio resistance is very high, polyester-cotton fabric wear use procedure can because of friction cause electrostatic phenomenon, lighter electrostatic phenomenon can make clothes attracting dust, or react with human body generation electrostatic, reduce the comfortableness of dress; In drier environment, electrostatic phenomenon may produce spark, and initiation fire causes security incident.On domestic piece market in recent years, surging gradually to moisture absorbing and sweat releasing textile demand cry, cause the concern of people in the industry, people are by physics and chemistry modification, or both associated methods are implemented to carry out modification to polyster fibre, prepare and can absorb rapidly skin surface moisture and sweat, by diffusion, be delivered to outer field hygroscopic fibre.
It silk is a kind of cellulose fibre, it is dry strong a little less than terylene, but apparently higher than general viscose rayon, wets and improve significantly than viscose glue by force, there is very high rigidity, good washing dimensional stability (washing shrinkage is only 2%), has higher hygroscopicity, and fiber cross section is circular or oval, gloss is graceful, soft, drapability is good, and elegant property is good; But it is easily hardening under damp and hot condition, cold water to choose suede also bad.
In the electrostatic sensitive such as explosion hazard area and precision instrument places such as liquid gasification station, gas station, oil depots; in order to avoid causing full accident because of electrostatic; protection staff's personal safety and national wealth safety; anti-static clothing must be worn; simultaneously; in fire-fighting and industrial production environment, usually require that clothes have the function of fire protection flame retarding.By cotton fiber, hygroscopic fibre and the blending by a certain percentage of sky silk, achieve between different fiber and have complementary advantages, the jean woven is endurable, moisture permeability is good.At present, most jean only possesses electrostatic-proof function separately, and meanwhile, existing jean is after flame-proof treatment, and feel is partially hard, and finishing technique process is complicated.Therefore, utilize simple technique to arrange jean, the fabric after arrangement, while having antistatic and anti-flaming function concurrently, meets it and takes requirement, has very important meaning to jean in the application of special industry.
Summary of the invention
The object of this invention is to provide a kind of fire-resistant antistatic jean, solve existing jean anti-static effect poor, the problem of antistatic and anti-flaming function can not be had simultaneously concurrently.

Take bipseudoindoxyl dye, be dissolved in water, stir, obtain the dye liquor that concentration is 20 ~ 80g/L, regulate pH value of solution to 4 ~ 7.5, mixed yarn prepared by step 1 is dyeed, obtains dyed yarn;
Step 3: painting cloth is weaved
Selecting step 2 gained dyed yarn, conductive filament are as the raw material of face weave, and by conductive filament and scribbled and twisting obtains conductive yam, in weaving process, interval inweaves conductive yam, obtained antistatic grid painting cloth;
Step 4: washing
Adopt the slurry that in destarch enzyme stripping weaving process, cloth cover produces, then wash out cloth style through rinsing, last cold water flush, dry and obtain Anti-static denim fabric;
Step 5: flame-proof treatment
Be that 5.5 ~ 7.5:1 takes fire retardant and magnesium chloride in mass ratio, and add appropriate amount of addition agent, be placed in water and dissolve, stir, obtaining concentration is the solution of 135 ~ 175g/L, being poured into by solution pads in groove, and the mode adopting two leachings two to roll is padded step 4 gained jean, and pick-up is 60% ~ 80%;
Step 6: drying and processing
Step 5 was padded the fabric of fire retarding treating liquid through 95 ~ 105 DEG C of oven dry, 180 ~ 200 DEG C bake after, cooling, obtain fire-resistant antistatic jean.
Feature of the present invention is also,
In step 1, raw-materially in mixed yarn to consist of: cotton fiber 40% ~ 55%, hygroscopic fibre 40% ~ 55%, tencel fiber 5 ~ 20%, above each weight percentages of components sum is 100%.
In step 3, conductive filament is the one in nylon based conductive fiber long filament, terylene base conductive fiber long filament or black carbon fiber electrically conductive filament, and the twist of gained conductive yam is 25 ~ 55 sth. made by twisting/10cm.
