When knitted textile layer clot in described step (2) is processed, it is ensured that knitted textile layer tensile stress stretching and roll up circle in the form of a roll under 0.5~0.9 kilogram of state, and edge cuts edging, knitted textile layer neat in edge is without burr。Knitted textile layer correspondence extravagance in described step (3) is carried out compound tense, knitted textile layer tensile stress is stretched under 0.5~0.9 kilogram of state corresponding compound, carry out knitted textile layer eliminating electrostatic simultaneously。Knitted textile layer is carried out elimination electrostatic and adopts a conductive light sliding rail rod, compound after making knitted textile layer derive electrostatic through smooth iron staff and smooth knitted textile layer surface and polyurethane film surface coating。By in described step (4) polyurethane film and the knitted textile layer of compound be placed on temperature 15-25 DEG C and carry out abundant compound with humidity 30%-70% relative humidity, holding time 50-100 hour。Standing time in described step (4) is 72 hours, temperature 20 DEG C with humidity 50% relative humidity in carry out abundant compound。
A kind of high gas permeable material, is made up of through gluing and rubberised layer (4) compound knitted textile layer (1) and polyurethane film (2)。Described polyurethane film (2) is provided with aperture (3), described aperture (3) diameter 30~100 microns。Described polyurethane film (2) upper punch 300-600 aperture of every 100 sq (3)。Described high gas permeable material Air permenbility is more than 2.0~4.0 liter/square meter per seconds (liter/sqm/sec)。
During real work, originally polyurethane film is mainly compounded between the cloth back side or two-layer knitted textile product with the technique of polyurethane film compound by the material of knitted textile product and polyurethane film compound by the knitting shortcoming non-watertight, not Radix Saposhnikoviae spinning product, uses the physical characteristic of polyurethane film to carry out Radix Saposhnikoviae, waterproof and moisture-inhibiting;Its moisture-inhibiting principle be the physical characteristic using polyurethane film by the hydrone of human body skin generation through with the physical exchange of polyurethane film after be discharged into outside clothes, thus can reach the function of waterproof, warming and moisture-inhibiting;But it is because human body static very big with the thermal difference of generation when moving, walking or user can often feel excessively sultry, moist because the molecular weight water of generation alreadys more than the emission limit of the material of knitted textile product and polyurethane film compound on the heat of at this moment human body generations and skin during motion, and user is excessively incubated。
General knitted textile product are below 0.4 liter/square meter per second with the material of polyurethane film compound at 100 handkerchiefs (Pa) pressure purgation Air permenbility in the market, although under so low ventilative condition can waterproof, warming and moisture-inhibiting but because environmental change and wearer movement amount increase can feel very sultry when wear, aqueous vapor and heat that human body skin in clothes discharges cannot be discharged near outside clothes and be accumulated inside clothes, and this can cause the discomfort sultry, moist of garment wearer to be internally formed the tiny globule even at clothes。
The ventilative processing technique of material height after a kind of knitted textile product and polyurethane film compound:
(1) material of knitted textile product Yu polyurethane film compound is placed on specific temperature (15-25 DEG C) and maintenance under humidity (30%-70% relative humidity) 72 hours, allow material moisture regain and bridge formation, this material making compound good can carry out high ventilative processing technique under complete stability state。
(2) inspection before high ventilative processing and clot steady quality degree before materials processing after accurately controlling its tension force (longitudinal tension force is at 0.5~0.9 kilogram) and flatness (adopt laterally expand cloth draw runner wheel expand cloth 5%) close inspection knitted textile product and polyurethane film compound, clot afterwards by justified margin (employing optics edge-adjusting device opposite side)。
(3) yardage roll is rolled out: controlled well by the cloth accomplishing fluently rolling after eliminating electrostatic with air blowing type static elimination bar after tension force (longitudinal tension force is at 0.5~0.9 kilogram) and flatness (adopt laterally expand cloth draw runner wheel expand cloth 5%) and roll out yardage roll and deliver to high ventilative processing unit (plant)。High ventilative processing unit (plant): adopt needle-like mould that knitted textile product are calculated the ventilative processing unit (plant) of suitable punching processing parameter height for using needle-like arrangement of molds density to be processed different air penetrability from polyurethane film composite according to the air penetrability of its physical property and dress materials design, it is divided into male and female mould, upper die mold bent axle principle carries out up and down reciprocatingly action and is punched out, and lower mold is for fixing to bear rapidoprint punching impulsive force。Having two groups of digital control selvage guides and work feed cylinder group, it is with mold knee-action connection line operation simultaneously, punching longitudinal pitch and density can be adjusted and so can control punching density and reach to adjust the effect of different air penetrability。
(4) trimming is synchronized: when clean edge in order to clothing processing factory cut out version operation accurate opposite side will be cut out with the round cutting knife of high speed rotating in material both sides through the material after too high ventilative manufacturing procedure and cut to reduce waste material。
(5) material batches: clot batch rolling after justified margin (adopting optics edge-adjusting device opposite side) after accurately controlling its tension force (longitudinal tension force is at 0.5~0.9 kilogram) and flatness (adopt laterally expand cloth draw runner wheel expand cloth 5%) after eliminating electrostatic with air blowing type static elimination bar after inspecting high ventilative Compound Machining quality。
(6) material packaging: stick shipping mark after packing according to customer requirement and get final product shipment。
High the adopted technique of processing of breathing freely looks dress designing to be needed necessary on average at 100 square centimeters of (mm with use2) upper punch 300-600 aperture of area, each hole is between 30~100 microns (micron);Processing technique controls these little hole number and size according to the material after different grammes per square metres and the knitted textile product of style and polyurethane film compound and dress designing demand calculating processing using and carries out the correct running of high ventilative number。
After too high ventilative processing more than 100 handkerchiefs (Pa) pressure purgation Air permenbility is up to 2.0~4.0 liter/square meter per seconds (liter/sqm/sec), this considerably increases the Air permenbility of clothing and fraction of vapor transfer rate (about 10), so it is possible not only to maintain script waterproof, warming and moisture-inhibiting function, aqueous vapor produced by human body skin and too much heat can being allowed again to be discharged at once outside clothing and allow the enough convection current of inner air and outer air, this can keep wearer dry and comfortable, comfortable and all without feeling sultry in various environment。
On dress materials use, its inside stuffing of many clothing (such as warming fiber and eider down) all cannot use because knitted textile product weaving process reason fiber gap each other is big when having much dress designing, because out can must only be used closely knit woven fabric as garment material when wearing by the interval training one another of its fiber;Causing warmth retention property not good because knitted textile product fiber gap each other is big again, knitted textile product can cause again the overheated outer clothing of wearer also the clothing of inside stuffing can have been allowed to rouse as balloon air bag effect can allow wearer's inconvenience action because air penetrability is not good with the material of polyurethane film compound。
But designers know that knitted textile product its outward appearance except than tatting softness also can seem closes the characteristic of Fashion Design agitation and many changes than higher gears comparison operators;In the past this made designer be difficult to select correct material because material on the market none can reach this requirement。
High ventilative processing can allow the problems referred to above be readily solved, allow knitted textile product with the material of polyurethane film compound because high ventilative processing technique has market widely, also the alternative product that simultaneously allowed the design of clothing many, makes garment market more diversified with design。
