Printing and dyeing production process of dustproof yarn

Abstract

The invention discloses a printing and dyeing production process of dustproof yarn, relates to the field of textiles, and aims to achieve the purpose of improving the dyeing effect of the dustproof yarn. The process is technically characterized by comprising the steps of (1) preparation of a conductive fiber yarn core, wherein polyester fiber is provided, and the surface of the polyester fiber isplated with copper by means of a chemical plating method to serve as the conductive fiber yarn core; (2) coating of the fiber; (3) singeing; (4) mercerizing treatment; (5) prefabricating of a dyeing agent; (6) ionized adsorption, wherein skein is arranged in an ionization chamber and positively charged or grounded, the prepared dyeing agent is led into an electrostatic sprayer, and high-voltage negative electricity is connected with a metal current guide pipe on a nozzle of the electrostatic sprayer, so that the sprayed dyeing agent is adsorbed on the skein; (7) drying; (8) forming. By utilizing the printing and dyeing production process of the dustproof yarn for ionized adsorption of the dyeing agent, the adhesion effect is good, and no pollutant can be generated.

Description

technical field [0001] The invention relates to the field of yarn printing and dyeing, more specifically, it relates to a printing and dyeing production process of dust-proof yarn. Background technique [0002] With the rapid development of the economy and society, the development of textile technology is also changing with each passing day, and new products of various functional yarns and fabrics are continuously introduced.

Problems solved by technology

However, fabrics with good dustproof properties can effectively prevent human body secretions and dust in underwear from being discharged to the environment, and at the same time prevent clothing from absorbing external dust and do not generate lint, thereby providing a clean working environment, such as patent No. The Chinese patent CN101008121A discloses a dust-proof composite yarn, in which the conductive fiber accounts for 10-30%, and the polyester long fiber accounts for 70-90%, wherein the conductive fiber contains conductive components, and The distribution of conductive components on the fiber cross-section is uniform or exposed. However, the dyeing and finishing process of the above-mentioned composite yarn is still using the traditional dyeing and finishing process, resulting in poor color adhesion, and a large amount of wastewater will be generated during the dyeing and finishing process. and consume huge energy
