Problems solved by technology

[0002] In the prior art, conventional printing mainly consists of screen printing and digital printing. Screen printing mainly includes rotary screen printing and flat screen printing. Poor, the printed fabric is hard, the hand feels poor, and the dyes used pollute the environment; although digital printing solves the problem of pattern resolution and clarity, the printing speed is relatively slow, generally only 10m 2 / h, and, limited by the digital printing machine, the printing width is limited, and most of them can only be printed on polyester-cotton and other fabrics, and pure cotton cannot be printed

Embodiment 1

[0025] The technological process of dyeing in the technical solution of the present invention is: printing color paste preparation→printing→drying.

[0026] (1) Preparation of printing paste: 5% (mass percentage) of No. 11 magenta and 95% (mass percentage) of 118A printing paste are selected as raw materials. The composition of the slurry is 15% (mass percentage) acrylic acid emulsion, 5% (mass percentage) water and 80% (mass percentage) sodium alginate, the three are mixed and stirred, the stirring speed is 2500r / min, and the processing time is 30 In minutes, printing color paste can be obtained.

[0027] (2) Printing: First, apply water-sensitive photosensitive glue evenly to the nickel screen, dry it at 40°C, then draw the sample and make a film, and then release the film; feed the printing color paste in step (1) into the screen or nickel screen, and start the rotary screen In the printing machine, the guide belt drives the fabric or fabric to move, and when the nickel me...

Embodiment 2

[0032] This embodiment is the same as Example 1, the difference is that the raw material selection is 2% (mass percentage) No. 31 royal blue and 98% (mass percentage) 118A printing paste, wherein the fineness of the finely ground royal blue is 250 mesh , the composition of the printing paste is 18% (mass percentage) of acrylic emulsion, 3% (mass percentage) of water and 79% (mass percentage) of sodium alginate, the stirring speed is 2000r / min, and the processing time is 20 minutes.

Embodiment 3

[0034] This example is the same as Example 1, the difference is that the raw material selection is 3% (mass percentage) of No. 21 magenta and 97% (mass percentage) of 118A printing paste, wherein the magenta fineness after grinding and finishing is 300 mesh , the composition of the printing paste is 25% (mass percentage) of acrylic emulsion, 5% (mass percentage) of water and 70% (mass percentage) of sodium alginate, the stirring speed is 2500r / min, and the treatment time is 30 minutes.

Abstract

The invention discloses a printing paste preparation and printing process thereof and belongs to the technical field of textile printing or printing. The method for preparing the printing paste comprises the following steps: performing finish machining on each raw material, and mixing with printing paste, wherein the pigment accounts for 1-10 mass percent, and the printing paste accounts for 90-99 mass percent. The printing paste prepared by the method is dyed, dried and set. By the adoption of the technical scheme, the problems that the design and color are not bright and the pattern definition is low during screen printing are solved, the defects of low yield and limited breadth during digital printing are overcome, the printing breadth is improved, the printing speed is high, and the speed is generally 3,000m / h; and moreover, the adopted pigment and base material are pollution-free green dyes, and the dye is environment-friendly, has the effects of energy conservation and emission reduction and can be widely applied to the textile printing or printing process.

Description

technical field [0001] The invention relates to the preparation of a printing color paste and its printing process, belonging to the technical field of textile dyeing or printing. Background technique [0002] In the prior art, conventional printing mainly consists of screen printing and digital printing. Screen printing mainly includes rotary screen printing and flat screen printing. Poor, the printed fabric is hard, the hand feels poor, and the dyes used pollute the environment; although digital printing solves the problem of pattern resolution and clarity, the printing speed is relatively slow, generally only 10m 2 / h, and, limited by the digital printing machine, the printing width is limited, and most of them can only be printed on polyester and cotton fabrics, while pure cotton cannot be printed. [0003] Based on this, make the present invention. Contents of the invention [0004] The object of the present invention is to provide a method for preparing printing co...
