Environment-friendly and activator-free water transfer film and transfer printing method thereof

Abstract

The invention provides a water transfer film with environmental protection and activator-free and a transfer printing method thereof. The steps include: laying a super absorbent film on a water surface; arranging a hydrophilic material on the surface of the super absorbent film to A hydrophilic material layer is formed, and the hydrophilic material can contain a message body, or another message body is coated on the hydrophilic material layer; the super absorbent film absorbs water and softens at the end face of the contacting water surface, and is cross-linked at the other end face. Hydrophilic material layer; a transfer object is laminated into water toward the hydrophilic material, so that the hydrophilic material layer and the superabsorbent film are transferred to the transfer object; thus, the present invention does not need to use an activator , the water transfer process can be carried out, which can avoid the environmental pollution caused by the use of activators, harm the human body, and cause the deformation of the transfer lines, and can reduce the water transfer time and raw material costs, thereby achieving environmental protection. It can improve the efficiency and production yield of water transfer printing.

Description

technical field [0001] The present invention relates to the technical field of water transfer film without using activator, especially a method of water transfer printing without using activator, so as to avoid environmental pollution, harm to human body and transfer lines caused by the use of activator Environmental protection and activator-free water transfer film and its transfer printing method that can avoid the effects of deformation and achieve environmental protection. Background technique [0002] Press, Water Transfer Printing (Water Transfer Printing) technology, which is mainly through printing graphics on water-soluble resin film and laying it on the water surface, and then hydrolyzing the water-soluble resin film into a free state through an activator, so as to convert the water-soluble resin film into a free state. The object to be transferred is pressed into the water from the top of the water-soluble resin film, so that the graphics and text can be transferr...

AI Technical Summary

Problems solved by technology

[0003] However, the activator of water transfer printing is an organic solvent, which has VOC (volatile organic compound) emissions, so whether it is produced, transported or used in the process of water transfer printing, it will volatilize and cause damage to the environment and ecology and harm The doubts of the relevant construction personnel; moreover, due to the spraying rate, uniformity, concentration, formula and other conditions of the activator, it will affect the dissolution of the printed graphics on the water-soluble resin film, and the process will lead to uneven dissolution. Factors such as the force generated by spraying and spraying will lead to deformation, which will affect the accuracy, aesthetics and production yield of water transfer printing
