Problems solved by technology

[0002] Due to the unreasonable design of the screen of the printing plate and the unreasonable setting of the parameters of the printing scraper and the setting of the color fixing parameters of the printing squeegee, the flat screen printing process used for clothing fabrics is prone to blurred patterns and outlines in the actual printing process. Blurred, low color fastness of printed pattern, uneven color

Embodiment Construction

[0014] In the following, the present invention will be further described in conjunction with specific embodiments, so as to understand more clearly the technical idea claimed in the present invention.

[0015] A flat screen printing process, comprising the following steps,

[0016] S1. Preliminary preparation;

[0017] S2. To print the pattern, first sort the printing plates in the order of shallow and then deep, and then replace the magnetic bar of the printing machine with a magnetic bar with a diameter of 13mm. The pressure of the printing scraper is 13-35kg, and the scraper speed is 0.8-2.5m / s , the scraper angle is ±3-±25°, and the scraping times are at least 5 times;

[0018] S3, post-processing, the fabric after the printing process in step S2 is sent to a pre-dryer with a temperature of 120°-180° to dry at a speed of 7-12m / s, and then the fabric is sent to a steaming temperature of 85 °-145°, steam pressure 0.4-0.5MPa in a steamer for at least 40 minutes, and finally...

Abstract

The invention discloses a flat screen printing technology. The flat screen printing technology comprises three steps including pre-preparation, decorative pattern printing and post-treatment, whereinthe pre-preparation step comprises two procedures of pulping and platemaking; in the platemaking procedure, the mesh number of a printing plate silk screen is 360 meshes; when a decorative pattern isprinted, printing plates are sorted according to the sequence from deep to shallow; then a magnetic rod of a printing machine is changed into a magnetic rod with the diameter of 13mm and parameters ofa printing scraping knife are subjected to optimized design; the post-treatment comprises three processes including pre-drying, steaming and water washing; the printing plate silk screen, the printing scraping knife and drying and color fixing parameters of the post-treatment are subjected to the optimized design and decorative patterns, which are clear and have high color fastness and uniform colors can be printed on a clothing fabric; the problems in a printing process that the decorative pattern is blurry, the outline is not clear, the color fastness of the decorative pattern is low and the colors are not uniform can be avoided.

Description

technical field [0001] The invention belongs to the technical field of garment fabric printing processing, and in particular relates to a flat screen printing process. Background technique [0002] Due to the unreasonable design of the screen of the printing plate and the unreasonable setting of the parameters of the printing scraper and the setting of the color fixing parameters of the printing squeegee, the flat screen printing process used for clothing fabrics is prone to blurred patterns and outlines in the actual printing process. Unclear, low color fastness of printed pattern, uneven color. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a flat screen printing process that helps to ensure clear patterns with high color fastness and uniform design and color are printed on clothing fabrics. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005...
