Abstract

The invention relates to an environment-friendly and energy-saving digital printing process which comprises the steps of fabric pretreatment, ink selection, direct injection printing, drying, baking, post-treatment, drying and finished product obtaining, and specifically comprises the following steps: 1) performing plasma treatment on a fabric which is not subjected to soft finishing treatment; 2) carrying out ink selection; (3) carrying out ink-jet printing on the pretreated fabric; 4) drying the printed fabric on a drying machine; 5) implementing a baking process; (6) through two-dipping and two-rolling post-treatment, enabling an auxiliary agent to act on the cloth cover to achieve a treatment effect; and 7) drying the post-treated fabric on a drying machine. A conventional paint is pretreated before digital printing, and corresponding ink is selected according to fabric components; and in the post-treatment, the printed fabric is further subjected to color fixation finishing, so that the color fastness is improved, the defects that the digital printing color of the paint is not bright enough and the dry and wet rubbing fastness is low are effectively improved, and the requirements of environmental protection and energy conservation are really met.

Description

technical field [0001] The invention relates to a digital printing process, in particular to an environment-friendly and energy-saving paint digital printing process. Background technique [0002] In recent years, the environmental protection and energy saving requirements of the printing and dyeing industry have become more and more stringent. Although the country is now beginning to use digital printing to replace some traditional dyeing methods, it is indeed more environmentally friendly, and it can also meet the needs of more and more small batches, multiple varieties, and customization. [0003] Compared with the traditional digital printing process, the general digital printing process greatly reduces the use and waste of dye ink, but there will still be some waste. The patent of the present invention mainly introduces a paint digital printing process, which simplifies the production process, without water washing and sewage discharge, and truly meets the needs of env...
