Problems solved by technology

Among them, the post-processing process requires the use of more harmful chemicals than inks, and also requires high-temperature treatment, which will volatilize the chemicals into the air, threatening the health of employees
[0005] At the same time, bacteria are everywhere. Many of the existing textiles are cotton fabrics or quilted fabrics, which are easy to breed bacteria in humid environments. If the human body is in close contact with such textiles for a long time, bacteria will become the cause of human disease and threaten the human body. healthy

Abstract

The invention discloses environmentally-friendly textile printing ink. The ink is prepared from the following raw materials, in parts by weight: 26-32 parts of a polyurethane binding material, 38-44 parts of alcohol-soluble color paste, 2-3 parts of an antibacterial agent, 20-30 parts of a solvent, 10-12 parts of a plasticizer, 1-2 parts of a stabilizer, and 4-6 parts of a rheological auxiliary agent. The invention also discloses a preparation method of the environmentally-friendly textile printing ink. According to the method provided by the invention, polyurethane is used as the binding material of the ink, a compound of ethanol, ethyl acetate and water is used as a solvent of the ink, the antibacterial agent is added into the ink, so that the obtained printing ink is energy-saving and environmentally friendly, has less pollution to the air, and meets modern environmentally-friendly requirements; the antibacterial agent is added, so that the ink has good antibacterial properties; through micro-amount assisted cooperation of auxiliary agents such as the plasticizer and the stabilizer, the mechanical properties and thermal stability of the ink coating can be improved; and the obtained environmentally-friendly textile printing ink has good stability, no color difference, good drying performance and antibacterial activity.

Description

technical field [0001] The invention belongs to the technical field of textile printing, and in particular relates to an environment-friendly textile printing ink and a preparation method thereof. Background technique [0002] The process of making color paste from dyes or pigments of various colors and printing them on textiles to form patterns is called textile printing. [0003] Due to the characteristics of textile materials, the textile printing process is divided into screen printing (rotary screen / flat screen), transfer printing and digital printing. The printing pigment ink (commonly known as ink) used in these three printing processes contains Many chemical elements that pollute the environment, so it is not environmentally friendly. [0004] The printing process is relatively long, generally including pattern design, pattern making, color paste preparation, pattern printing, drying, post-processing (steaming, washing, finishing) and other processes. Among them, t...
