Automatic high temperature disappearing car line paste and preparation method thereof

Abstract

The invention relates to an automatic high-temperature stitching disappearing paste and a preparation method thereof. The automatic high-temperature stitching disappearing paste is prepared from the following raw materials in parts by weight: 40 parts of purified water, 0.3 part of raising agent, 10 parts of automatic de-coloring powder and 0.5 part of mixing liquid. The preparation method comprises the following steps of: weighing the purified water, the raising agent, the automatic de-coloring agent and the mixing liquid in parts by weight, placing the materials into an agitator and agitating the materials evenly; grinding the mixture obtained by means of the agitation into paste by using a grinder and filtering through a filter; and cooling the filtered pasty mixture at normal temperature for 1 hour and packaging in barrels. Compared with the traditional stitching pastes, the automatic high-temperature stitching disappearing paste has the following beneficial effect of causing the stitching to disappear without white marks after baking at high temperature of 75 DEG C for 6 minutes, so that the trouble of cleaning vamps is excused, the cleaning labor cost is saved and the vamps are ensured to have original leather color without water cleaning.

Description

technical field [0001] The invention relates to the field of printing materials, in particular to an automatic high-temperature disappearing thread paste and a preparation method thereof. Background technique [0002] At present, when printing shoe uppers at home and abroad, it is necessary to print the track with white thread paste on the front leather surface of the shoe upper, so that the sewing workers can go to the sewing machine according to the lines. However, the traditional sewing thread is pasted on the shoe surface after the sewing machine. Because there are white spots beside the thread, it is necessary to send workers to scrub the shoe surface and keep it clean. This causes a waste of labor to a certain extent. A normal production line starts from It will waste 3-6 people from needle car to molding, and what is even more frightening is that some leather such as: imitation fur and nubuck leather are pasted with traditional printing car thread, because they will b...
