Cotton transfer printing paper and its machining method

Abstract

A transfer paper for printing on cotton fabric is composed of paper, isolating layer and dye layer. Its preparing process includes such steps as concentrating sodium silicate glass liquid, coating it on paper, baking, regulating the pH value of dye slurry to 4-5, printing the patterned dye layer on the surface of dried sodium silicate glass layer, and chemical reaction to generate an isolating layer between them.

Description

(1) Technical field [0001] The invention relates to transfer printing paper for cotton printing, and also relates to a processing method of the printing paper. (2) Background technology [0002] Transfer printing is the technology of continuously transferring pre-printed patterns from printing paper to fabrics. The printing paper and the fabric are in continuous contact with each other in a transfer area, and the pattern transfer is realized by pressing rollers. At present, transfer printing is divided into two types, namely heat transfer and cold transfer. The thermal transfer process uses hot-melt ink to transfer to the fabric by hot pressing. Before the thermal transfer, the surface of the fabric is coated with a modified treatment solution that can accept ink dyes. This treatment solution is easy to destroy the natural characteristics of cotton fibers, making Cotton fabrics lose their original air permeability, softness, and water absorption, so the heat transfer proce...

Problems solved by technology

This increases the process in actual operation, and it is difficult to achieve the goal of shortening the transfer time and transferring fully through the action of the catalytic layer. First, the catalytic layer and the isolation layer are on both sides of the carrier paper, and the dye layer is in isolation. The surface of the layer, so that the catalytic layer cannot touch the dye layer before it penetrates into the carrier paper and the isolation layer, that is, when it penetrates into the dye layer, the carrier paper has already been crushed under the strong pressure of the pressure roller, and the transfer cannot be achieved.
