Digital printing process for polyester fabric

Abstract

The invention discloses a digital printing process for a polyester fabric. The process comprises the following steps that a digital printing thickner is prepared; a pretreatment agent is prepared; thepolyester fabric is cleaned by adopting deionized water, dried, and then placed in the pretreatment agent in S2, dipping is carried out twice, rolling is carried out twice, then the polyester fabricis taken out and dried to obtain a pretreated fabric; then sizing treatment is performed on the surface of the pretreated polyester fabric in S3 through the thickner obtained in S1; after the surfaceof the pretreated polyester fabric is sized, the pretreated polyester fabric is sent into a hot press, and the fabric is placed in a high-temperature high-pressure environment for hot pressing; the hot-pressed fabric in S5 is dried. A printing thickner colorant has stable colored light, bright color, a high color yield, a clear printing outline and good washing fastness and rubbing fastness, and is environmentally friendly and safe; the use of the pretreatment agent on the fabric can improve the mechanical properties of the fabric; the whole process is simple to operate, has a good printing effect and low cost, and the obtained pattern effect is exquisite and beautiful.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a digital printing process for polyester fabrics. Background technique [0002] Digital printing is printing using digital technology. Digital printing technology is a high-tech product that integrates machinery, computer, electronic information technology and gradually formed with the continuous development of computer technology. In recent years, digital printing technology has developed rapidly. Compared with traditional printing, digital printing has a clean process, flexible production process, remote ordering, and integration into the supply chain network. It is the direction of future textile printing technology development. However, due to the characteristics of polyester, its fabric surface is relatively smooth, and inkjet printing cannot achieve the expected effect in practical applications. There are many problems, such as the color depth of inkjet printing ...

Problems solved by technology

However, due to the characteristics of polyester, its fabric surface is relatively smooth, and inkjet printing cannot achieve the expected effect in practical applications. There are many problems, such as the color depth of inkjet printing on textiles is not enough, and the color difference with electronic patterns is large etc., thereby limiting the development of inkjet printing of textiles, so the surface of polyester fabrics needs to be treated to improve the color fastness of digital printing on the surface of polyester fabrics, therefore, a digital printing process for polyester fabrics is needed
