Abstract

The invention relates to an indigo blue jean fabric made of aramid fiber. The indigo blue jean fabric is formed by interweaving warp and weft which include meta-aramid fiber. The warp is formed by blending, by weight, 19%-79% of dyed meta-aramid fiber, 19%-78% of dyed fire resistant viscose fiber and 1%-3% of antistatic fiber. When the dyed meta-aramid fiber is navy blue, the dyed fire resistant viscose fiber is dark blue, and when the dyed meta-aramid fiber is dark blue, the dyed fire resistant viscose fiber is navy blue. The weft is formed by blending, by weight, 97%-99% of raw white meta-aramid fiber or dyed meta-aramid fiber and 1%-3% of antistatic fiber. Compared with the prior art, the indigo blue jean fabric made of the aramid fiber has the advantages of being smooth, cool, breathable, antistatic and gorgeous after being dyed.

Description

A kind of indigo jean

Technical field

The present invention relates to a kind of garment material, particularly a kind of non-fire-retardant, environmental protection indigo jean through post processing be made up of aramid fiber.

background technology

Denim (Denim) is also called tannin fabrics, is that a kind of thicker look is knitted through face jean, and warp thread color is dark, and be generally indigo, weft yarn is of light color, is generally the raw white yarn after light gray or kiering.Also known as indigo denim.Start from US West, the personnel that herd gain the name in order to make clothing, the existing popular whole world.

The sewage that tradition denim produces in process is difficult, serious environment pollution, or the burden adding factory because sewage disposal device cost is high.Traditional denim is not washable, not wear-resisting simultaneously, and COLOR FASTNESS is poor, and especially some physical properties of denim are as anti-flammability, heat resistance, the limitation of electrical insulating property, under severe conditions, should not use as industrial work clothes.At present at home and international, realize the anti-flaming function of denim, usually arrange in process and will add fire retardant, but fire retardant is very harmful to environment, the U.S. prohibitted the use and add fire retardant in denim from 2011.

For the anti-flaming function of fabric, useful meta-aramid replaces cotton yarn as the technology manufacturing garment material at present.Meta-aramid full name poly(isophthaloyl metaphenylene diamine), english abbreviation MPIA, another name aramid fiber 1313, its molecular structure is arrange the regular large molecule of sawtooth pattern, just decomposed before melting, vitrification point Tg is 270 DEG C, can not occur significantly to decompose and carbonization below 350 DEG C.When temperature is more than 400 DEG C, fiber gradually embrittlement, charing until decompose, but can not produce molten drop; Combustion is not prolonged in flame, there is good anti-flammability, limited oxygen index LOI is 29%-32%, there is excellent heat-resisting quantity, good DIMENSIONAL STABILITY, excellent spinnability, fire line and corrosion resistance, be a kind ofly to develop early, application is wide, output is large, develop fast high-temperature fibre kind, its total amount occupies the second of special fibre.Can be used for fire-entry suit, forest People's Armed Police clothes, the vamp of army's footwear and shoestring etc.

Present denim dyeing is mainly carried out yarn with bipseudoindoxyl dye.Only dyeed in the top layer of yarn, yarn interior fiber difficulty or ease dye, like this when jean adds man-hour through wearing away, after the very thin one deck dyestuff of yam surface is ground off, expose more white yarn core, color and luster is shoaled very soon, thus makes clothes after the short time wears away, the adverse consequences of fading immediately.

summary of the invention

Object of the present invention is to overcome aforementioned the deficiencies in the prior art just, one is provided not only to have fire-retardant, heat-resisting, the performance of electric insulation, also has the manufacture method of a kind of indigo COARSE DRILL cloth jean made by aramid fiber that washable and wearable not easily fades or do not fade.

For this reason, technical scheme provided by the invention is: this indigo jean, formed by the warp thread and weft yarns that comprise meta-aramid composition, warp thread is by dyeing meta-aramid fibers, dyeing flame retardant viscose and antistatic fibre blending form, the percentage by weight of the meta-aramid fibers that wherein dyes is 19%-79%, the percentage by weight of dyeing flame retardant viscose is 19%-78%, the percentage by weight of antistatic fibre is 1-3% and dyeing flame retardant viscose is royalblue when the meta-aramid fibers that dyes is navy, when the meta-aramid fibers that dyes is royalblue, dyeing flame retardant viscose is navy, weft yarn is formed by colour prime white meta-aramid fibers or dyeing meta-aramid fibers and antistatic fibre blending, and the percentage by weight of the meta-aramid fibers that wherein dyes or the meta-aramid fibers that dyes is 97%-99%, and the percentage by weight of antistatic fibre is 1-3%.It is to be noted that Fire resistant viscose fiber is the cellulose fibre produced for raw material with cotton or other natural fabric at this.Its moisture percentage meets the physiological requirement of human body skin most, have smooth nice and cool, ventilative, antistatic, dye the characteristic such as gorgeous.

Preferably, the composition of said antistatic fibre is polyamide or the polyethylene terephthalate of living.

Preferably, warp thread is blending after mixing with dye Fire resistant viscose fiber again after being mixed with antistatic fibre by dyeing meta-aramid fibers.

The present invention compared with prior art, not only have fire-retardant, heat-resisting, the performance of electric insulation, and due to the present invention be not the color with bipseudoindoxyl dye yarn being dyeed but produces after directly utilizing navy meta-aramid fibers to mix with royalblue Fire resistant viscose fiber, the clothes made can not produce the adverse consequences of fading after washing, wearing and tearing, and interpolation Fire resistant viscose fiber not only has fire-retardant, heat-resisting performance, and have smooth nice and cool, ventilative, antistatic, dye gorgeous characteristic.
