Description
Technical field：
The present invention relates to leather correlative technology fields, and in particular to a kind of production method of the upper leather of highly-breathable.
Background technology：
Upper leather is the raw material for making shoes, the surface for making shoes is used in, with Chinese shoes already presented production
Industry Clustered Development state, causes China's leather industry to be rapidly developed, and production scale expands, increase of production, technological progress
Accelerate, product quality also accordingly improves.There are many raw material of technology of waterproof shoe upper leather at present, there is corium upper leather, PU upper leathers, PVC shoes
Upper leather etc..The preferable technology of waterproof shoe upper leather of quality, grain is thinner, soft, and wearability is all relatively good, but preferable after all
Corium limited amount, causes cost to improve.And common water-proof vamp grain is more coarse, Boardy Feeling, intensity is low, folding resistance with
And wearability is all bad, is easily deformed, and is handled even across sanding, it is still uncomfortable and existing with the position of skin contact
The vamp material of some leather shoes cannot be taken into account in waterproof, comfort level, endurable quality, folding line and ventilative performance.
In existing upper leather technical field, CN201621295337.0 discloses a kind of environmental protection breathable synthetic leather,
Its key points of the technical solution are that including leather substrate in this application utility model, the corium being equally spaced is sewed on leather substrate
Portion, flexible part is sewed between corium portion, and flexible part includes being recessed to leather substrate direction to reduce flexible part apparent height
Loose lines, the side wall in corium portion are equipped with for increasing and the extension of the contact area of flexible part, and corium portion increases this
The aesthetic appearance on synthetic leather surface, flexible part help to enhance the pliability of synthetic leather, and the loose lines on flexible part surface has
Help the gas permeability of the synthetic leather, extension keeps the connection of corium portion and flexible part even closer, in use the conjunction
It is not easy to be scattered at leather, so, the synthetic leather soft-touch, thinner thickness gas permeability is good, has excellent usage experience sense,
And the leather has both environmental protection characteristic after aqueous polyurethane impregnates.
A kind of synthesis air permeable waterproof upper leather is disclosed in CN201720670512.8, one is disclosed in this application utility model
Kind synthesis air permeable waterproof upper leather, including upper leather main body, the upper leather bottom part body are provided with cellucotton bottom, the fibre
Vinylon and cotton blend bottom top is connected with leather substrate, and the leather substrate is equipped with the first air hole, is set above first air hole
It is equipped with unsaturated zone, the second waterproofing membrane is fixedly connected at the top of the unsaturated zone.The utility model passes through in suede and leather
Multiple air holes are formed in base, to solve the permeability of upper leather, and make vamp using the processed synthetic leather,
Due to the micro-pore diameter very little on the first waterproofing membrane, the second waterproofing membrane and third waterproofing membrane, visually see in appearance not
Out, it both ensure that gas permeability, also effectively reach waterproof effect, suede is compound so that upper leather main body jail with corium paste layer
Gu durable, simple in structure, laminating degree is high, and good permeability is comfortable and easy to wear, is suitble to be widely popularized.
