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

[0015] A kind of printing technology of printing color paste, described technological process is:

[0016] (1) Preparation of printing paste: in parts by weight, mix 5 parts of 11# red, 20 parts of acrylic emulsion, 30 parts of water and 50 parts of sodium alginate, and stir at 1500r / min for 20min to obtain ;

[0017] (2) Printing: apply water-sensitive photosensitive glue on the screen, then dry it at 40°C, and finally draw the sample to make a film, and then output the film; feed the printing color paste in step (1) into the screen, and start the rotary screen printing machine, the guide belt drives the fabric, and when the screen rotates synchronously with the guide belt, the printing paste overflows through the small holes on the screen, and then prints on the fabric;

[0018] (3) Drying: the fabric processed through step (2) is dried in a steam box, and the temperature of the steam box is 120° C.;

[0019] (4) Shaping: the dried fabric is shaped for 15 minutes at a temp...

Embodiment 2

[0021] (1) Preparation of printing paste: in parts by weight, mix 10 parts of 31# blue, 50 parts of acrylic emulsion, 20 parts of water and 60 parts of sodium alginate, and stir at 1500r / min for 20min to obtain ;

[0022] (2) Printing: apply water-sensitive photosensitive glue on the screen, then dry it at 60°C, and finally make a sample and produce a film; feed the printing color paste in step (1) into the screen, and start the rotary screen printing machine, the guide belt drives the fabric, and when the screen rotates synchronously with the guide belt, the printing paste overflows through the small holes on the screen, and then prints on the fabric;

[0023] (3) Drying: the fabric processed through step (2) is dried in a steam box, and the temperature of the steam box is 100° C.;

[0024] (4) Shaping: the dried fabric was shaped for 20 minutes at a temperature of 80°C.

Embodiment 3

Abstract

The invention discloses a printing technology of printing color paste. The technology comprises the steps of printing color paste preparing, film making, platemaking, sample making, drying and shaping. The printing technology solves the problems that pattern and color in screen printing is not bright, and the pattern definition is poor and overcomes the detects that in digital printing, the yield is low, and the breadth is limited. The printing breadth is increased, and the printing speed is high.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a printing process of commonly used printing color paste. 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. Contents of the invention [0003] In view of the above-mentioned problems existing in the prior art, the applicant provides a printing process of printing color paste. The pro...
