Description
The invention discloses the manufacture method of water-proof air-permeable shoes for use both in sunny lining, belong to the innovation and creation of daily necessities footwear.
Along with the raising and the inhabitation urbanization of standard of living, for a long time, people wish that the footwear worn can waterproof, again vapour thoroughly.Dress all feels comfortably cool under any weather conditions, needn't worry for the overcast and rainy vexed pin of traditional rain boots of putting on, and this both will plant saturating vapour, the gum shoes surfacing material of waterproof again, softness comfortable and easy to wear.And its lining of traditional cloth shoes is a cotton fabric, its saturating vapour, good hygroscopicity.For the anti-footwear lining that loses shape need carry out starching and handles, but starching rear vamp material cloth hole is blocked and adopts during shoemaking, thereby steam-proof, and it was not only non-watertight but also to feel pin vexed to put on this footwear, and footwear can be smelly, and pin is easily given birth to the ringworm of the foot.This has become the difficult problem of shoe industry long-term existence puzzlement.Many inventors handle the gum shoes surfacing material fabric with water repellent agents such as silicone, fluorine carbons in order to solve this difficult problem.Though accomplish that steam permeability is good, not wear-resisting, not anti-fold, water proofing property difference and life-span are short, just lose water resistance after the washing for several times.EP0110627 has selected for use the polytetrafluoroethylene (PTFE) of not being afraid of wrinkle to make water-repellent layer and other fabric is compound, can be wear-resisting, fold, permanent waterproof, but the hydrophobic film material must be the super high molecular weight resin, be difficult for obtaining, and the fabric compound with hydrophobic film must be to select the polymer that has hydrophilic radical for use, or, expand away its saturating vapour amount＞1000g/m by hydrophobic film to help steam with the textiles that hydrophilizing agent is handled
2, day, saturating vapour amount＞2000g/m in the time of preferably
2, day, hydrostatic pressing is 250mm, 15 minutes are non-leakage.Yet, really reach rainproof, just must hydrostatic pressing play the 1400mm water column, it is just qualified to reach the 2000mm water column during extra torrential rain, and it is that little amount of exercise needs 1000g/m that people's saturating vapour amount comfortable and easy to wear requires
3, day, middle amount of exercise need reach 2000-2500g/m
2, day, large amount of exercise need reach 3500-4000g/m
2, day, if lower the requirement the EP0110627 patent is difficult to accomplish water-proof air-permeable, with the gum shoes surfacing material of this patented method making and the water-proof air-permeable difficult problem of unresolved footwear.And the saturating vapour amount of hydrophobic film itself that this patent is made is little, and compound footwear material will pass through sizing technique, passes through sulfuration process again.More can not satisfy the requirement of waterproof and saturating vapour amount after these technologies.
The purpose of this invention is to provide a kind of can waterproof the manufacture method of the gum shoes surfacing material of vapour thoroughly again, that gum shoes surfacing material constructed in accordance has is wear-resisting, wrinkle, permanent waterproof and the saturating measured characteristics of vapour.
For reaching the object of the invention, can be in order to method realization down, quote the disclosed compound gum shoes surfacing material structure of Chinese patent ZL932258514 weather air-permeable shoes: lining-water-repellent layer-lining material, its water-repellent layer is that the water-proof air-permeable film is to apply for a patent the saturating steam film of polytetrafluoroethylene (PTFE) hydrophobic (PTFE) that the disclosed manufacture method of 941120570 inventions is used the low-molecular-weight resin gained, its saturating vapour amount＞1000g/m by China
2My god, its hydrostatic pressing of resistance to water＞6000mm water column, 2 hours non-leakage, water feeler＞90 °, have crease-resistant, to roll over, draw performance and have certain elasticity be a kind of very desirable water-proof air-permeable material, the film and the fabric of the saturating vapour amount of this height are compound, its fabric needn't carry out hydrophilic treatment, compoundly also needn't select hydrophilic vapour glue such as polyethers-poly-urethane etc. for use with binding agent, therefore compound gum shoes surfacing material does not have hydrophilic layer, lining, lining and hydrophobic film compound, available various natural, to synthesize adhesives directly compound.Example ordinary hot melten gel or curing glue, the ordinary hot melten gel has the copolymerization and the blend of polyamide, polyester, polyethylene, vinyl acetate etc.Its method is with the glue hot melt, be coated on film above, put lining and lining material respectively for two of film then, at hot down bonding compound gum shoes surfacing material.Compounded fabric is soft, not well-pressed, not starching after selecting for use the fabric of different-thickness, density compound, can be made into garment material, silo drop cloth, tent cloth, instrument and equipment cover, they all have the excellent waterproof permeability performance, being used for the compound material of shoemaking need pass through sizing technique, can make just that compound material is well-pressed a skeleton, classical starching raw material is use rubber solutions, with after its starching thoroughly the cloth of vapour hole plug with regard to steam-proof.Therefore sizing agent of the present invention be with a kind of itself be the polymer substance that has hydroxyl, ether, amido, epoxy radicals of the waterproof also air proof of vapour, its method for sizing still routinely technology carry out.Compound gum shoes surfacing material through starching, have well-pressed characteristics after the drying, the polymer substance of slurry enters the hygroscopic vapor transmission that does not influence fiber in the cotton fiber, and to increasing certain moisture after the chemical fibre starching of moisture absorption not, therefore its hygroscopic vapor transmission of compound gum shoes surfacing material after the starching good human body is not had yet times watch influence, and can resist 150 ℃ again, 90 minutes vulcanizing treatment.Therefore can satisfy the technological requirement of shoe industry and keep the excellent waterproof permeability performance.
By embodiment, the various superperformances of compound gum shoes surfacing material can be described better.
