CS225192B1 - Surface treatment of shoe bottoms made of sole leather - Google Patents

Description

FIELD OF THE INVENTION The invention relates to a method for treating the surface of leather underwear made of underwear, in particular cuts of leather lining, heels, heels of thermoplastics wrapped in foil made by cross cutting ^{1 of} glued underwear, unit lining made by spraying made by cross-cutting the glued leggings and the sole of the leggings.

In the prior art methods of surface treatment of sub-panels made of sub-leather, finishing wax dispersions made of natural, synthetic waxes and emulsifiers are used. Sole sections are pre-stressed with a hot body, then stained and dewaxed. Mixtures containing dyes, pigments, colloid, binder and water are used as incision dyes. Firing waxes include carnauba wax, paraffin and coloring agents. The soles and heels are painted after finishing. After drying the paints are painted with wax and after re-drying are polished on the polishing wheels. The disadvantage of this treatment method is the high labor intensity and low resistance of the waxes to mechanical influences, thus reducing the aesthetic properties of the final product in use. Another method is the treatment with nitrocellulose lacquers. The disadvantage of this method is the low resistance to external influences and solvents, and the solvent system of lacquers disrupts the strength of the glued joint of the glued heel slices or the glued frames. We use the mentioned varnishes also adversely affects the ecology of the environment.

These disadvantages are overcome by the method of surface treatment of the underwear parts made of underwear according to the invention, which is based on the fact that a thermoreactive acrylate dispersion is applied to the treated surface, which crosslinks after drying at temperatures of 120 to 140 ° C.

The technical effect of the invention lies in the reduction of the surface treatment of the bottom panels, the higher resistance of the film thus formed to mechanical and weathering influences, the influence of organic solvents and the improvement of the working environment.

In order to elucidate the invention, the following are examples of uses according to the invention.

Example 1

An aqueous dispersion of styrene and acrylic monomers containing the reactive mono225192 SOKRAT 942 is applied on the face of the glued back leather to the cut and the bottom of the bottom leather sole. The blanks thus prepared are inserted into the cavity of the press tool and sprayed with a thermoplastic such as PVC. The heat generated by the melt spray causes the monomers to cross-link, thereby forming an elastic, water-resistant and organic solvent-resistant film on the cut and face of the sole.

Example 2

Apply the aqueous dispersion of styrene and acrylic monomers containing the reactive monomer SOKRAT 942 to the film produced by cross-cutting the glued back leather. The thus prepared film is inserted into the cavity of the pressing tool and sprayed with a thermoplastic, such as polystyrene. The heat created by the melt spray creates an elastic, water-resistant and organic solvent-resistant wax film on the heel.

Example 3

A layer of styrene and acrylic monomers containing a reactive monomer SOKRAT 942 is applied to the unit heel of the heel formed by nailing the leather and the sole of the leather. diispersion fixes.

Claims (1)

Method of surface treatment of underwear parts made of underwear, characterized in that a thermoreactive acrylate dispersion is applied to the treated surface, which crosslinks after drying at temperatures of 120 to 140 ° C.
