Abstract

The invention discloses a heat transfer printing method of a silica-gel screen mesh, comprising the following steps of: (1) processing transfer paper; (2) coating CPU adhesive and PI hot melt powder by using the screen mesh; (3) coating hot melt adhesive and PI hot melt powder by using the screen mesh; (4) coating silica-gel and a curing agent by using the screen mesh; (5) drying; and (6) hot stamping at high temperature. The invention not only has reasonable and practical method, good practical effect, wide generalization and favorable guaranteeing of benefit and economy, but also can ensure that printing finished products have environment-friendly performance and soft hand feeling and are not easy to fall off and fade. meanwhile, the printing finished products has favorable washing bearing force on receiving articles (clothes), small volume and convenient transportation; and in addition, printing shops deliver the products to manufacturers at lower transportation cost for hot stamping, so that the transportation cost and the time of the manufacturers can be saved.

Description

technical field [0001] The invention relates to a silica gel screen thermal transfer printing method. Background technique [0002] Conventional screen printing methods are performed under normal atmospheric pressure, and there are screen printing using a stencil such as metal and screen printing using a screen composed of a gauze plate. In the former screen printing using a stencil such as metal, the stencil is brought into contact with the printing surface of the printed matter, and the pattern formed by pouring a paste-like or ink-like coating into the hole of the stencil is printed without using a squeegee. Covered, printed by a squeegee. [0003] CN02149136.4 discloses a screen printing method. In this screen printing method, the object to be printed is placed at a predetermined position on the printing table, a paste-like or ink-like coating is supplied to the surface of the screen for printing, and a squeegee is used to slide on the surface of the screen to print on...
