Abstract

The invention relates to a digital printing non-slurry preprocessing method for silk cloth. The method comprises a padding step, a drying step, a jet printing step, an ageing step, a washing step and a drying step, wherein padding liquid configured in the padding step comprises 0.2-1 g / l of softener, 0.2-1 g / l of water repellent, 20-40 g / l of sodium chloride and water; the solution concentration ratio of the softener to the water repellent is 1 to 1; the padding liquid is prepared by the steps as follows: adding the water, the softener and the water repellent, uniformly stirring, and adding sodium chloride; the softener belongs to a mixture of a cationic softener or cations and a nonionic softener, and comprises a quaternary ammonium salt softener, fatty acid ester softener and a paraffin wax softener; and the water repellent belongs to a weak cation water repellent and is a perfluoroalkyl polyacrylic copolymer. Due to the adoption of the non-slurry preprocessing process, the printed product is excellent in fineness, the obtained color is rich and gaudy, the color light is stable, and the overall quality is improved.

Description

technical field [0001] The invention relates to a slurry-free pretreatment method for silk digital printing. Background technique [0002] As a brand-new printing method, digital inkjet printing has developed rapidly in recent years and represents the development trend of the textile printing field in the future. Compared with traditional printing, digital printing has four advantages: (1) The plate-making process in traditional printing methods is omitted, which greatly speeds up the printing and proofing speed, and reduces the proofing cost. (2) It is not limited by the size of the flower circumference and the number of sets of the pattern. It has precise pattern matching, rich layers, and good printing effect. It can be used for printing high-end textiles. (3) Realize the small batch and quick response customer needs, and can produce high-grade and personalized printing products. (4) On-demand inkjet, little pollution before and after printing. The printing and dyeing ...
