Once-through method of aluminum-plating film resin transfer printing

Abstract

The invention relates to a once-through method of aluminizer resin transfer printing, which is used in the thermal transfer printing technology and comprises the following steps: A. after hot melting resin is hot-melted into liquid, a photogravure press is used for printing a pattern on the aluminium layer of the aluminizer under the condition of keeping the melting state of the resin, and after being cooled to room temperature, the aluminizer is rolled up for standby; and B. when printing is needed, the surface of the aluminizer with the hot melting resin pattern is adhered on a printing stock, treated with impressing at the temperature of between 85 DEG C to 120 DEG C, and the thin film is stripped away after cooling, thus forming the finished product. The method combines the traditional transfer printing of two times, i.e., the pattern thermal transfer printing and the transfer printing of a metallic film layer plated with a metallic film, into the transfer printing of one time, the transfer printing pattern is distinct and smooth, the luster is strong, the color is abundant, and stereoscopic impression can be given.

Description

technical field [0001] The invention relates to thermal transfer printing technology. Background technique [0002] The printing and dyeing industry of fiber fabrics and leather has become a world-wide strictly restricted industry due to serious environmental pollution. However, no matter how restrictive and what kind of wastewater treatment in the factory, it cannot overcome the discharge of a large amount of wastewater, which has prompted all walks of life. Technicians go to study a new non-polluting or less polluting printing technology route, and then thermal transfer printing technology, supercritical carbon dioxide dyeing technology, etc. appear. There are also many kinds of thermal transfer printing technologies, basically in A transfer film is printed with a resin pattern. After the resin is cured, the side of the transfer film with the resin pattern is pasted on the fiber fabric to be printed, or on the leather. After hot pressing, the resin pattern is transferred t...

AI Technical Summary

Problems solved by technology

However, a large amount of organic solvents are used in the existing thermal transfer printing, such as methyl ethyl ketone, cyclohexanone, and toluene, which are volatilized in large quantities when printing resin patterns, causing serious pollution in the workshop

In addition, if the surface of the printed surface is not smooth, such as leather, the surface of the resin pattern will not be smooth after thermal transfer, resulting in a rough surface and poor gloss.
