　　 shoes There are two types of impurities on the surface: silver pencil line and solid impurity Such as glue overflow and dust, which make particles produced in the process of modification; The other is oil stain, wax sensitive agent, hand feel agent, oil sensitive agent, sweat spot, etc. These impurities cause the phenomenon of scuffing, pinhole, paint peeling, etc. during the vamp modification. The role of cleaning is to remove these two kinds of impurities and lay the foundation for the next process.

2、 Function of cleaning extender

The extender contains special surfactant ingredients, which can soften the skin and expand the pores, enhance the clarity of the grain surface, clean the water-soluble impurities and residual oily cleaner in the leather, enhance the permeability and wettability of the leather, improve the leveling, improve the adhesion, and thus facilitate the penetration, bonding and leveling of the modified materials in the next process, If the extender is not applied, it is easy to appear blossoming, whitening, and poor bonding.

3、 Function of filler

The filler contains a unique penetrant, which can make the treatment agent penetrate into the pores, play the role of bonding between the leather fiber and the finishing layer, obviously improve the adhesion of the paint, remove the small wrinkles on the leather surface, fill the pores, and make the skin more plump and compact.

4、 Function of brightener

improve Upper Gloss, hand feel, wax feeling and color can also cover the natural defects of the leather surface to a certain extent, and have a certain protective effect on the vamp, enhancing the waterproof, antifouling, wet rub resistance, folding resistance and other properties.

5、 Function of filling wax
