Embodiment Construction

[0034] The needle punching netting method of the present invention comprises the following steps: 1. coating thermosetting powder slurry on the screen; 2. needle punching with color separation patterns; 3. heating and curing.

[0035] figure 2 Shows the schematic diagram of the mesh making method of the present invention, step 1 coating thermosetting powder slurry on the screen includes: tensioning the screen 1 on the flat mesh frame 2, such as figure 1 shown; then the thermosetting powder slurry is coated on the screen 1 to block the mesh, and after drying, the coating screen 6 is obtained; the thermosetting powder slurry is a mixture of thermosetting powder and glue, and the particle size of the thermosetting powder is between 0-200 μm, the thermosetting powder is hot-sol powder, the melting temperature is lower than 150° C., and the hot-melt powder is nylon hot-sol powder.

[0036]Step 2 color separation pattern injection includes: fixing the coating screen 6 on the print...

Abstract

A matrix print method for preparing the screen plate includes coating the thermosetting paste on screen, matrix printing according to the color separating pattern, heating and solidifying. Its apparatus is composed of vertical main frame, screen locating-locking unit, high-precision 2V driver, printing carriage, matrix print head on said carriage and computer.

Description

technical field [0001] The invention relates to a method and equipment for making a textile printing screen, in particular to a method and equipment for making a screen by needle punching. Background technique [0002] Textile printing is to scrape and print the color paste with dye on the fabric through the fine holes of the screen to produce color, and the printed shape is determined by the block pattern left on the screen that can pass through the fine holes of the printing color paste. [0003] As early as the 1950s, there was a photosensitive netting method. With this method, the original pattern must be drawn in different colors to make a "black and white film", that is, the pattern shape of each color Trace onto special film with black ink. The so-called "photosensitive screen making method" is to add light-sensitive substances such as ammonium dichromate into a special viscous glue, and then apply this glue to a blank screen plate, and dry it in a dark room at low t...
