Repair technology for leather clothing with coating cracks

Abstract

The invention discloses a repair technology for leather clothing with coating cracks. The repair technology comprises steps such as cleaning, filling, sizing and the like. The key process of the repair technology is the filling process, which is the key to solve the cracks of the coating. In the filling formula, excellent filling ability and permeability of filling type acrylic resin are utilized to radically realize the purpose of filling cracks and solving chromatic aberration. Meanwhile, the excellent penetrating quality of the filling fluid enables the formed resin film to form an extremely thin three-dimensional netted structure on the surface layer and inner part of the lather, so that the bonding firmness of the film is very high. The lather clothing treated by the repair technology has uniform, smooth and flat surfaces and bright color, and solves a problem that the leather clothing is difficult to repair due to cracks of coating after being worn for a long time. The repair technology provided by the invention can be used for repairing the leather clothing with coating cracks.

Description

technical field [0001] The invention relates to a method for refurbishing leather garments, in particular to a process for repairing cracked leather garments. Background technique [0002] During long-term wearing of leather garments, due to constant friction and scratches on the coating, or due to improper maintenance, the coating will be thinned, exposed and even cracked, which not only affects the appearance, but also And once fine cracks appear in the coating and come off, it will cause the complete scrapping of leather garments, directly resulting in economic losses. [0003] In the prior art, when cracks appear on the surface of the crust leather, the usual method is to first clean the leather surface, then use a leather crack repair paste, and finally use a leather renovation dyeing agent. The specific operations are as follows: [0004] Step 1 (use leather oil film cleaner or denatured alcohol): [0005] Find a relatively absorbent dry cloth, pour leather oil film ...

AI Technical Summary

Problems solved by technology

[0011] The above-mentioned repairing method adopts the combined use of leather cracking repair paste and leather renovation dyeing agent, but the repairing film formed is relatively thick, and then the fastness is not good, and cracks and shelling are prone to occur, which makes the repaired The leather is unnatural and destroys the original texture of the genuine leather; in addition, the above repair methods are aimed at the leather fabric, and the existing garment repair methods are much more complicated than the repair of the leather fabric

[0012] Chinese invention patent application CN102500539 discloses a "repair and renovation process of the two-layer film commercial method with partially peeled off coating", which adopts steps such as grinding, cleaning, scraping, secondary grinding, brushing the adhesive layer, and brushing the surface paste. The surface of the rear sofa is uniform and flat, which solves the problem that the coating of the two-layer film sofa is partially peeled off and is difficult to repair and refurbish. Some parts of the fabric should be easy to bend, and the coating should not be too thick or too hard, otherwise it will feel uncomfortable to wear; moreover, there is a big difference between clothing and sofa leather, because the sofa is thicker, larger in area and flatter. , can be sanded and scraped with emery cloth, and leather for clothing is not suitable for sanding and scraping because it is relatively thin
