Aqueous fluorescent invisible stitching plaster and preparation method thereof

Abstract

The invention relates to an aqueous fluorescent invisible stitching plaster comprising the following materials by weight part: 10-20 parts of thickening agent, 0.1-0.9 part of decomposition agent, 0.5-1.5 parts of distiller liquor and 65-80 parts of purified water. A preparation method of the aqueous fluorescent invisible stitching plaster comprises the following steps: infusing the thickening agent, the decomposition agent and the distiller liquor into the purified water for 2-3 hours and then pouring into a stirrer to stir for 1.5-2 hours, and then adding a proper amount of fluorescent powder after cooling for barreling and packaging. The invention has the advantages that: 1. the aqueous fluorescent invisible stitching plaster can ensure that a printed white mark is invisible under natural light compared with the traditional white and grey stitching plaster, thereby avoiding the trouble of cleaning the vamp and saving the labour cost for cleaning; 2. the printing output can be increased by about 1 / 3 to 1 / 2, a halftone can be prevented from being blocked and is hard to scrap, printing is easier for workers, the output and the quality are more stable; and 3. the aqueous fluorescent invisible stitching plaster can save much illumination power charge.

Description

Technical field [0001] The invention relates to the field of printing materials, in particular to a water-based fluorescent invisible car thread paste and a preparation method thereof. Background technique [0002] The water-based fluorescent invisible sewing thread paste is used on the printed shoe surface, because the front leather surface of the upper sewing machine must be printed with a traditional white marking line, so that the sewing worker can follow the line to the sewing machine. The traditional marking printing used in the past is called "white Water-based car line paste". The disadvantage of the traditional white water-based car thread paste is that it will block the printing screen and will fall off during the handling process after printing, which will affect the stitching line. Moreover, after the shoe upper stitching, because of the leakage of white spots beside the stitching line, workers need to be sent. Scrubbing the cleanliness of the shoe surface is a waste...

AI Technical Summary

Problems solved by technology

The disadvantage of the traditional white water-based thread paste is that it will block the printing screen, and it will fall off during the handling process after printing, which will affect the sewing line, and after the shoe upper is stitched, there are white spots beside the thread, so workers need to be dispatched Scrubbing the cleanliness of the upper is a waste of manpower. A normal production line will waste 3-6 people from sewing machine to molding

What is even more frightening is that some leather such as: imitation fur and nubuck leather are pasted with traditional printing lines, because they will be absorbed into the surface of the leather body, and white marks will appear again after cleaning, and because the surface of the leather will harden after washing , discoloration, or even mildew, seriously affecting the quality
