Embodiment 1

[0062]Prepare modifier 3-chloro-2-hydroxypropyltrimethylammonium chloride solution 120g / L and sodium hydroxide solution 20g / L volume ratio 1:1 and mix evenly, then pad pure cotton fabric fabric, fabric specification 40×40, 133×72, one dipping and one rolling, the liquid retention rate is 75%. After drying at 100°C, bake at 120°C for 1.5min. Next, wash with water at room temperature, wash with hot water at 95-98°C twice, wash with water at room temperature, wash with 2 g / L citric acid solution to neutralize water, wash with water at room temperature, and dry at 100°C.

[0063] The digital printing is normally printed, and after drying at 100°C, the fabric is steamed in a steam box at a steaming temperature of 100-103°C and a steaming time of 10 minutes.

[0064] Prepare 80g / L aqueous solution of sodium polysulfonylstyrene, pad and pad the steamed fabric with a liquid retention rate of 75%, and then dry it at 100°C.

Embodiment 2

[0066] Prepare modifier epoxy propyl trimethyl ammonium chloride aqueous solution 60g / L, sodium hydroxide aqueous solution 10g / L, mix evenly at a volume ratio of 1:1, then pad and pad pure cotton fabric fabric, fabric specification 40×40, 133 ×72, one soaking and one rolling, the liquid retention rate is 76%, and it is stacked at room temperature for 24 hours. Next, wash with water at room temperature, wash with hot water at 95-98°C twice, wash with water at room temperature, neutralize and wash with 2g / L citric acid solution until nearly neutral, wash with water at room temperature, and dry at 100°C.

[0067] Digital printing is normally spray printed, dried at 100°C, and the fabric is steamed in a steam box at a steaming temperature of 100-103°C and a steaming time of 10 minutes.

[0068] Prepare 80g / L aqueous solution of sodium polysulfonylstyrene, pad the steamed fabric with 75% liquid, and then dry it at 100°C.

Embodiment 3

[0070] Prepare modifier 3-acrylamide-2-hydroxypropyltrimethylammonium chloride 80g / L, sodium hydroxide aqueous solution 10g / L volume ratio 1:1 and mix evenly, then pad pure cotton fabric fabric, fabric specification 40 ×40, 133×72, one soaking and one rolling, the liquid retention rate is 76%, and it is stacked at room temperature for 24 hours. Next, wash with water at room temperature, wash with hot water at 95-98°C twice, wash with water at room temperature, neutralize and wash with 2g / L citric acid solution until nearly neutral, wash with water at room temperature, and dry at 100°C.

[0071] Digital printing is normally spray printed, dried at 100°C, and the fabric is steamed in a steam box at a steaming temperature of 100-103°C and a steaming time of 10 minutes.

[0072] Prepare 80g / L 2-naphthalenesulfonic acid formaldehyde polymer sodium salt aqueous solution, pad the steamed fabric with 75% of the liquid, then dry at 100°C

Abstract

The invention provides a digital printing process of a cellulosic fiber fabric. The digital printing process comprises the following steps: sequentially carrying out pretreatment modification, water washing, drying, digital printing jet printing, drying, ageing and post-treatment on the cellulosic fiber fabric, wherein the modifier for pretreatment modification is a cationic modifier, and the auxiliary agent for post-treatment is an anionic auxiliary agent. According to the method provided by the invention, a thickener sizing agent is not needed for sizing, the washing process can be reduced or washing is not needed after printing, the wastewater treatment cost is reduced, zero chromaticity of wastewater can be truly achieved, and meanwhile, the digital printing white ground is prevented from staining.

Description

technical field [0001] The invention belongs to the technical field of printing prevention, and in particular relates to a digital printing process of cellulose fiber fabrics. Background technique [0002] Digital printing has the characteristics of no screen making, low energy consumption, no waste, and high precision, and can adapt to the market of personalization, small batches, and fast delivery. The cost of digital printing ink is relatively high, and the color fixation rate of reactive dye ink is about 70%, which causes a lot of waste of reactive dye, and increases the chroma of sewage, making sewage treatment difficult. [0003] Chinese patent CN 108589347 A discloses a finishing method based on cationic modifier ink for reactive dye inkjet printing. The cationic modifier ink and reactive dye ink are spray printed on the sized cellulose through the inkjet printing process. The pattern area of ​​the fiber fabric is steamed or baked, and finally soaped to obtain a reac...
