Description
Technical field
The present invention relates to a kind of manufacturing methods of footwear, especially with regard to a kind of shoemaking installation step.The present invention is separately closed
In a kind of amendment solution that aforementioned shoemaking installation step is applied.
Background technology
The manufacturing method of general footwear include there are many step of and program, one of which method be by material be rubber and
The sole of EVA (plastic of poly vinyl acetate) is connect with vamp material (substrate), and sole and vamp bonding are fitted together,
The material of aforementioned vamp can be PU (polyurethane), synthetic leather, leather, reticular structure or fabric；
In order to which vamp and sole can reliably and firmly be combined, for each component (sole, vamp) of shoes
Continuous preprocessor need to be bestowed, such as：Degreasing, polishing, brushing, baking oven heating, label and coating adhesive, and aforementioned painting
Sole or vamp can be individually coated on by covering the program of adhesive, can also be coated on sole and vamp simultaneously；
Adhesive commonly used in shoemaking is the adhesive suitable for PU (polyurethane), and such adhesive can be with different shape
Mode present, such as：The kenels such as solution, adhesive, hot melt film and powder hot melt adhesive (TPU- thermoplasticity PU).
Wherein, using solution, adhesive as solvent/water base rubber " formation " application, it will be generated before the drying of aforementioned adhesive agent
About 100-200 microns of wet layer thickness, and adhesive agent drying activation after, thickness be 20-60 micron, therefore, be coated with compared with
In the case of thick glue layer, the drying time grown very much is needed, and need to consume higher energy；Conversely, in adhesive
In the case that layer coating is relatively thin, the case where may result in adhesive force insufficient even failure (air chamber for sticking surface), it is based on
Previous reasons, coated in the single layer solvent/water base rubber on single surface and can not to provide shoe parts (sole and vamp) appropriate
Adhesion.
Aforementioned to solve the problems, such as, the solution of industry is through on sole and vamp while coating gluing respectively
Agent/promoter layer needs to divide on sole and vamp respectively in the case of certain special (characteristic for depending on material)
It is not coated with double-deck binder, can realize adhesion amount appropriate.
Good binder between sole and vamp part is to use powder hot melt thermoplastic polyurethane (TPU) binder, such as
No. 20140093655 shoe parts gluing method of U.S. Patent Application No. of Orisol companies application is to use thermoplastic poly
Urethane (TPU) arogel.
Caused by the chemical characteristic of thermoplastic polyurethane (TPU), the program of solvent/water evaporation is needed not move through,
And can only coat the thickness of 100 to 500 microns of single layer, thus just can only be coated on wherein side (sole and vamp
Wherein side) on, then by viscous liquid layer will be coated in or through electrostatic force technology gluing to shoes materials surface, it can
It is attached on any 3D substrates in shape.
It is applicable to any shoe parts material type of gluing (porous material or dense material), and is executing in short term
It is all environmental protection in activation process and does not have toxic solvent (VOC) volatilization.
Although TPU materials possess outside aforementioned advantages, it is understood that there may be some limitations, such as：
In order to realize bonding appropriate between material for sole of shoe (material coated with TPU binders) and vamp material, need
To have and be applicable in various vamp materials or different types of brushing composition, each brushing composition all have specific viscosity with
Porosity with vamp material to be binded.
For example, full-bodied priming paint (3000- may be needed by being easy to the porous vamp substrate (such as net) of glue penetration
6000cP) filling pore；
And low-viscosity priming paint (being less than 3000cP) will infiltrate into the bottom of web material without being formed continuously in web material surface
It sticks together, therefore, the big material of density may need first to be handled with the primer solution of low-viscosity, so that inorganic agent can be easier to ooze
Thoroughly in material hole.
In order to " processing " corresponding different characteristics vamp material, it is necessary to handle and manage different types of inorganic agent,
With the demand suitable for different materials, thus will lead to the problem of inventory and the problem of term of validity, in turn result in high
Expensive expense.
In addition, in known shoemaking installation step, sole and vamp all need cumbersome pretreatment, specific implementation method
As shown in Figure 1：

Rapid 53, coating powders step 54；
Vamp must be executed sequentially：Cleaning step 61, markers step 62, coating processing step 63, the second baking procedure 64；
Drying and processing step 71, assembling steps can be carried out after sole and vamp have executed foregoing pre-treatment step
72, process is quite cumbersome.
