Description
Technical field
The present invention relates to a kind of waterproof moisture permeable fabric and processing method thereof and purposes, be specifically related to a kind of Waterproof Breathable coating fabric of being obtained by a cutter coating and processing method thereof and purposes.
Background technology
In short time motion and durable motion, mainly comfortableness is referred to the requirement of gym suit performance.And in moving out of doors, can extraneous factor be resisted to requiring to include of gym suit performance, such as strong wind, sunlight, sleet etc., should be able to help to keep health and extraneous heat balance simultaneously, namely, when body metabolism speed is accelerated, clothes can help human-body radiating, perspire.
Along with the development of high functional coating and laminated fabric production technology, the waterproof moisture permeating fabric that wherein can manage body surface moisture is not only specious, ventilative, and comfortableness is good, and can resist extraneous factor.
Existing waterproof moisture permeating fabric is typically employed on fabric and carries out two-layer dry coating, containing coating enhancer in ground floor, to ensure coating agent and good suddenly the putting forth effort of base cloth; The hot melt polyurethane resin contained in the second layer is in order to improve the wearability in glue face and the water pressure resistance of fabric of fabric.Because needs twice coating causes final coated weight comparatively large, generally about 30-80g/m
2, fabric feeling is comparatively hard, and finished product easily has sound.Special on the light and thin fabric of current trend, thick and heavy coating also can cause product style to change.
In patent document CN102535165A, introduction be a kind of waterproof and breathable coated fabric, have employed the conventional coatings technique of primer+face glue, coating process relative complex, cost is higher, and product stable uniformity is bad.
Summary of the invention
The object of the present invention is to provide a kind of technique simple and low production cost, processed the waterproof moisture permeable fabric of the soft handle obtained and processing method thereof and purposes by a cutter dry coating.
Waterproof moisture permeable fabric of the present invention, this fabric at least comprises Ji Bu and urethane resin film.Meet the condition of following (1) ~ (3):

(3) according to JIS L 1092 B method, the water pressure resistance of this fabric is 500 ~ 8000mmH
2o; According to JIS L 1099 B method, the moisture permeability of this fabric is 5000g/m
2.24h more than.
The thickness of above-mentioned urethane resin film is 10 ~ 150um.
The preparation method of waterproof and breathable coated fabric of the present invention, comprises the steps:
(1) woven fabric of coverage coefficient between 1800 ~ 3000 is selected first to carry out waterproof resin processing as base cloth.If the coverage coefficient of woven fabric is less than 1800, the front of the fabric that coating adhesive can permeate, can cause that fabric has pitch streak, if coverage coefficient is greater than 3000, fabric face is more coarse, uneven, causes gluing irregular.And to the woven fabric of coverage coefficient in particular range first do waterproof resin processing be to tentatively give base cloth water proofing property.The present invention preferably adopts carbon 6 waterproof resin to carry out padding processing to make base water washing durability (20 times) of deploying troops on garrison duty reach more than 80.
(2) again the Ji Bu of step (1) is carried out press polish process, obtaining gas permeability is 0.3 ~ 10cm
3/ cm
2the cloth of/s.This is the glossiness in order to improve fabric face, makes fabric face more smooth, is convenient to that coating adhesive is more homogeneous entirely to be adhered to.
(3) then on the base cloth trowel finish of step (2), polyurethane resin solution is coated with by a cutter dry coating processing, obtain product, wherein polyurethane resin solution here, comprises following composition: polyurethane resin 100 weight portion, surfactant 4 ~ 7 weight portion, mill base 0 ~ 10 weight portion, bridging agent 1 ~ 10 weight portion, promoter 0.1 ~ 1.0 part, curing agent 0.5 ~ 5 weight portion.
Surfactant is silicone-based, and bridging agent is melamine class or isocyanates, and promoter is organic amine.
The resin of the preferred solid content 15 ~ 60% of the present invention's polyurethane resin used, viscosity 70000 ~ 90000 (CPS/25 °).
Waterproof of the present invention, moisture-permeable shell fabric can directly use, also stamp processing can be carried out at face, or to fit again one deck woven fabric or knit goods at the opposite side of Ji Bu, can be used for making leisure jacket, charge garment, combat trousers, athletic competition clothes, CRUX clothes etc.
