Embodiment 1

[0024] Prepare 100g of digital printing pretreatment agent:

[0025] Weigh 11g of urea, 1g of baking soda, 0.8g of antioxidant, add 85.92g of water, and stir on a stirrer. After all the ingredients are dissolved, weigh 2g of sodium carboxymethylcellulose and slowly add it under stirring. Continue to stir for 2 hours, stop stirring, and puff for 8 hours for later use.

[0026] Padding pretreatment agent: padding car pressure 2kg, one dipping and one rolling, the excess rate is 78%, and drying after padding is completed, and the drying temperature is ≤100°C.

[0027] After digital printing is normally printed, place the viscose fabric in a steamer to steam at a steaming temperature of 102-105°C for 8 minutes, wash in cold water, wash in hot water, wash in cold water, and dry.

Embodiment 2

[0039] Formulating digital printing pretreatment agent:

[0040] Weigh 7 parts of urea, 0.5 parts of baking soda, and 0.5 parts of ascorbic acid, add deionized water, stir, and weigh 1 part of hydroxypropyl methylcellulose after all the ingredients are dissolved, and slowly add hydroxypropyl methylcellulose during the stirring process. For methyl cellulose, continue to stir for 1-2 hours until the paste is fully dispersed, stop stirring, and puff for 6-10 hours for use. The viscosity of the digital printing pretreatment agent is less than 20000mPa·S. .

[0041] Padding pretreatment agent: under the condition of 2kg pressure, one dipping and one rolling, the excess rate is 100%, and drying after padding, the drying temperature is ≤100°C.

[0042] After normal digital printing, place the viscose fiber fabric in a steamer to steam at a steaming temperature of 105°C and a steaming time of 7 minutes. The washing process includes: cold water washing→hot water washing→cold water was...

Embodiment 3

[0044] Formulating digital printing pretreatment agent:

[0045] Weigh 25 parts of urea, 2 parts of baking soda, and 2 parts of astaxanthin, add deionized water, stir, and weigh 3 parts of hydroxyethyl cellulose after all the ingredients are dissolved, and slowly add hydroxyethyl cellulose during the stirring process. For cellulose, continue to stir for 1-2 hours until the paste is fully dispersed, stop stirring, and puff for 6-10 hours for use. The viscosity of the digital printing pretreatment agent is less than 20000mPa·S. .

[0046] Padding pretreatment agent: under the condition of 2kg pressure, one dipping and one rolling, the excess rate is 70%, and drying after padding, the drying temperature is ≤100°C.

[0047] After normal digital printing, place the viscose fiber fabric in a steamer to steam at a steaming temperature of 102°C and a steaming time of 10 minutes. The washing process includes: cold water washing→hot water washing→cold water washing, and finally drying....

Abstract

The invention belongs to the technical field of textile printing and particularly relates to a digital printing process of an artificial cellulose fiber fabric. The digital printing process comprisesthe following steps of preparing of a digital printing pretreatment agent, padding of the pretreatment agent, digital printing spray printing, steaming, washing and drying. The digital printing pretreatment agent comprises, by weight, 1-3 parts of a thickener, 7-25 parts of urea, 0.5-2 parts of printing alkali, 0.5-2 parts of an antioxidant and the balance water. According to the process, the antioxidant is added to the pretreatment agent, so that the problem of yellowing of the fabric caused by oxidation in the drying or steaming process under the alkaline condition of the phenolic substancescan be effectively prevented. Compared with a digital printing process in the prior art, the whiteness of the fabric produced by the digital printing process of the artificial cellulose fiber fabricis remarkably improved, the fabric printing gradation is clear, the stereoscopic impression is remarkable, and the product color is bright. The digital printing process has the beneficial effects of simple process, easy operation and convenient product quality control.

Description

technical field [0001] The invention belongs to the technical field of textile printing, in particular to a digital printing process for man-made cellulose fiber fabrics. Background technique [0002] Man-made cellulose fiber fabrics include viscose fiber and modal fiber fabrics. Man-made cellulose fiber fabrics have good moisture absorption and moisture conductivity, are cool to wear, light in texture, good in resilience and wear resistance, and are good clothing fabrics. Digital printing is printing using digital technology. The pattern is input into the computer in digital form, edited and processed through the computer printing color separation and drafting system, and then the computer controls the micro piezoelectric inkjet nozzle to spray the special dye directly into the computer. On textiles, the desired pattern is formed. The digital printing process has the characteristics of no need for net making, low energy consumption, no waste, and high precision, and can ada...
