Embodiment Construction

[0008] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0009] Such as figure 1 As shown, the present invention provides a non-woven silk screen printing process, which is used to carry out silk screen printing on the surface of the non-woven fabric 10, comprising the following steps:

[0010] (1), install the net, select the selected screen plate 20 and install the screen plate 20 on the screen printing equipment, the density of the oil drop holes 21 on the screen plate 20 is 100~120T;

[0011] (2), stick low mucous membrane 40, low mucous membrane 40 is pasted on the screen printing platform 30, the glue face 41 of low mucous membrane 40 is upwards, ...

Abstract

A nonwoven fabric silk printing technology comprises the following steps: (1), installing a net, an appropriate net plate is selected and installed in a silk printing device; (2), sticking a low mucosa, the low mucosa is stuck on a silk printing platform and a rubber surface of the low mucosa is upturned, wherein the silk printing platform is provided with some multiple through-holes which a upper end thereof is extended to a table-board of the silk printing platform and a lower end thereof is ran through the silk printing platform and is connected with an external air pump; (3), loading material, the nonwoven fabric is placed on the low mucosa; (4), adding a ink, the ink is pour on the net plate, wherein the ink is a conductive ink and a viscosity of the ink is 200dpa.s-300dpa.s; (5), silk printing. The nonwoven fabric silk printing technology effectively solves a problem that the nonwoven fabric is stuck on the net by using the low mucosa as a bearing material. Based on the low mucosa, a silk net T number, a scrapping printing speed, a scraper pressure and a parameter of the silk printing are adjusted, which can solve an oil leakage of the nonwoven fabric and an unevenness of the silk printing and improve the silk printing quality of the nonwoven fabric.

Description

technical field [0001] The invention relates to a silk screen printing process, in particular to a non-woven silk screen printing process. Background technique [0002] The objects of silk screen processing in the printed circuit board industry are rigid printed boards (epoxy resin or modified epoxy resin sheets), flexible printed boards (PET or PI glued / glued-free flexible materials), traditional silk screen printing The equipment is also designed according to the characteristics of the printed circuit board. Non-woven materials have the characteristics of air permeability, water permeability, and water absorption. Using traditional printed circuit board processing methods to screen-print on non-woven fabrics, serious oil seepage and web sticking problems cannot be solved. Therefore, the silk screen printing of non-woven fabrics has been perplexing technicians in the industry, and a new non-woven silk screen printing technology is urgently needed to make up for the deficie...
