Abstract

The invention discloses a heat-transfer printing technology for pure cotton cloth. The heat-transfer printing technology comprises the following steps: (1) pretreatment of the pure cotton cloth: soaking the pure cotton cloth in an acrylic ester monomer solution for padding pretreatment, carrying out shaping and drying, and then carrying out graft polymerization modification according to a low-temperature plasma technology; (2) preparation of heat-transfer printing paper: printing transfer paper by utilizing a disperse dye, and drying the prepared heat-transfer printing paper and the disperse dye in an electric oven after printing; (3) heat-transfer printing: adhering the heat-transfer printing paper to the front surface of the pure cotton cloth subjected to graft polymerization modification on a heat-transfer printing machine for heat-transfer printing; (4) rolling for packaging and warehousing. The heat-transfer printing technology provided by the invention is novel in design, pollutant-free, environmentally friendly and lower in resource consumption; the pure cotton cloth printed according to the heat-transfer printing technology is bright in color, relatively high in color fastness to washing and softness, comfortable to wear, and broad in market prospect; the heat-transfer printing technology is a novel method for environment-friendly and efficient printing and dyeing of cotton and other fabrics containing natural fibers.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a heat transfer printing process for pure cotton cloth. Background technique [0002] Compared with the traditional printing process, the transfer printing process does not require steaming and washing processes, and has the advantages of saving water and energy. In addition, transfer printing fabrics have high artistry, fine contours, clear layers, and strong three-dimensionality, which are incomparable to traditional printing fabrics. However, thermal transfer printing cannot print fabrics containing natural fibers such as cotton, because the molecules of natural fibers such as cotton contain a large number of hydrophilic groups, while the existing dyes that can be thermally transferred do not contain hydrophilic groups. There is no binding force between them, so that the dyeing effect of the product is poor, and the color fastness is not good. The prior art is to...
