Problems solved by technology

[0004] 1) The existing technology is molded by vulcanization, and each LOGO needs a mold with LOGO, and the mold cost is expensive, and the production mold is about 15,000 yuan per pair;
[0005] 2) Due to the limitation of the size of the button, the size of the LOGO on the mold must be very small and thin, which is easily damaged;
[0006] 3) Due to the need to manufacture molds in the existing technology, the general production cycle is more than one month, which cannot meet the customer's rapid response requirements

Abstract

The invention relates to the technical field of garment accessory production, and particularly relates to a method for removing a laser mark of a urea-formaldehyde resin button. The method for removing the laser mark of the urea-formaldehyde resin button comprises the steps of A) polishing the urea-formaldehyde resin button after laser treatment; and B) soaking the urea-formaldehyde resin button obtained in the step A) in post-treatment liquid for a period of time, taking out the urea-formaldehyde resin button, and cleaning the urea-formaldehyde resin button to obtain a laser mark removed urea-formaldehyde resin button, wherein the post-treatment liquid comprises the following components in parts by weight: 100 parts of water; 1-15 parts of trisodium phosphate, 0.5-1 part of a surfactant,and 1-10 parts of sodium silicate. According to the removing method, LOGO on the surface of the button is not whitened, and characters are consistent with the bottom color of the button. Moreover, theurea button with the colorless LOGO can be manufactured without using a LOGO mold, the effect and the performance of the manufactured product meet the colorless requirement of a customer for the LOGO, the production cost is effectively reduced, and the production period is shortened.

Description

technical field [0001] The invention relates to the technical field of garment accessories production, in particular to a method for removing laser marks on urea-formaldehyde resin buttons. Background technique [0002] Button products are widely used in clothing, shoes and hats, and are a common type of clothing accessories. At present, common button products on the market are mostly made of unsaturated polyester resin, urea-formaldehyde resin, plastic or metal materials. As a popular button substrate, urea-formaldehyde resin is widely used in various garments. The products are diversified. Customers demand urea buttons with LOGO. However, due to the characteristics of urea-formaldehyde resin material, whitening will inevitably occur after laser engraving. This cannot meet the customer's demand for the urea-formaldehyde resin buckle LOGO not to change color. [0003] The method adopted in the prior art to solve the above-mentioned problems is: making a mold with LOGO, and...
