Hot-melting veiled car line paste and preparation method thereof

Abstract

The invention relates to a hot-melting veiled car line paste and a preparation method thereof. The car line paste is composed of 100 parts of high-saturated fatty acid, 5 to 10 parts of polyoxyethylene-type nonionic surfactant and 180 to 220 parts of purified water. The preparation method comprises the following steps of: 1) putting the high-saturated fatty acid and the polyoxyethylene-type nonionic surfactant into a container; heating to the temperature of 70 to 80 DEG C and melting, thereby preparing an oil phase; 2) slowly dropwise adding the purified water preheated to the temperature of 70 to 80 DRG C into the oil phase in a stirring manner; after dropwise adding, heating to the temperature of 78 to 85 DRG C; preserving heat and stirring for 30 minutes, thereby obtaining an emulsifying body; and stirring and cooling to the room temperature, thereby obtaining the hot-melting veiled car line paste. By adopting the screen plate printing, a white positioning line formed on the surface of a fabric material is clear, long in retention time and free of blocking a screen plate during the printing process. The positioning line can be automatically molten to disappear after the fabric material is shaped in a processing manner, and cannot generate any residual trace. The raw materials and the product provided by the invention are safe, environment-friendly and free of toxic effect to a human body.

Description

technical field [0001] The invention relates to the field of printing materials, in particular to a hot-melt concealed thread paste used in the production of shoes, clothing, bags and leather and a preparation method thereof. Background technique [0002] In the production process of shoes, clothing, luggage and leather, it is necessary to sew different shapes or sizes of leather, woven fabrics and velvet into designed patterns. Thread paste is such a fine chemical product, which is printed on the surface of raw materials such as leather, woven cloth, and velvet in the production process of shoes, clothing, bags, and leather by screen printing to form lines, which are used as sewing marking lines for positioning. It is used for cutting, sewing, and sewing along the line to ensure that the shape will not be skewed or deviated. Lin Qingfu (CN102702843A) discloses a water-based thread paste and a preparation method thereof, which is prepared by mixing powdery bentonite and cal...

Problems solved by technology

It will cause blockage of the screen during use, making it impossible to print clear and uniform lines through the screen

In addition, the substances that disappear automatically at high temperature mainly refer to solid sublimation substances such as elemental iodine, sulfur, and liquid mercury. After sublimation, these substances become gases and disappear in the surrounding environment, causing harm to the human body and affecting human health.
