Abstract

The invention relates to a cotton fabric digital printing technology, and belongs to the technical field of digital printing. The cotton fabric digital printing technology comprises following steps: 1, pretreatment, wherein fabric is immersed in a pretreatment solution for dipping finishing, wherein the temperature of the pretreatment solution is controlled to be 25 to 50 DEG C, and the pretreatment solution contains hydroxyl-terminated polysiloxane, mercapto or isocyanate alkoxy silane, an alkali agent, and a thickening agent; 2, corona treatment, wherein after pretreatment, the fabric is dried, and is subjected to corona treatment in the air; 3, inkjet printing, wherein after corona treatment, the fabric is subjected to inkjet printing using a digital inkjet printing machine, wherein theadopted ink is active dye ink. The cotton fabric digital printing technology is suitable for small batch customized processing of cotton fabric, and is suitable for batch printing treatment at the same time, is friendly to the environment, is simple in technical operation, and is capable of improving printing clearness, color brilliant degree, and color fastness obviously.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular, the invention relates to a digital printing process for cotton fabrics. Background technique [0002] The development of cotton textiles has a very long history in our country. Cotton fabrics are deeply loved by consumers because of their good wearing comfort. Although synthetic fibers have been widely developed and used in the past hundred years, cotton fabrics are still the most important. One of the most popular clothing raw materials, it has the characteristics of soft hand feeling, strong and durable, strong hygroscopicity and good dyeing performance. At present, my country's textile production capacity accounts for about half of the world. With the continuous expansion of the textile market, the cotton textile industry, especially some high-end cotton product industries, is developing more and more rapidly. In the traditional technology, printing on cotton fabrics n...
