Problems solved by technology

The pure cotton cloth printed by this method has dark color and unsatisfactory soaping fastness
In addition, there are also methods for acetylation grafting, resin spraying and swelling of cotton fabrics to achieve thermal transfer printing, but these methods are all due to serious damage to the fabric, toxicity, or hard hand feeling, or color fastness. Unsatisfactory and other reasons have not yet been applied in batches

Abstract

The invention discloses a cotton fabric thermal transfer printing method belonging to the printing and dyeing technology. In the method, the fabric is first pretreated by padding and bridging agent, and the paper or metal foil printed with a pattern is attached to the pretreated fabric. After a short heat press on the transfer machine, the fabric can be printed and dyed with bright colors and firm patterns. The fabric is soft and washable, and it is comfortable to wear. The method is a clean printing and dyeing technology without harm to human skin and without environmental pollution, and has universal popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, in particular to a thermal transfer printing method for cotton fabrics capable of carrying out a clean printing and dyeing process of transfer printing on fabrics Background technique [0002] Thermal transfer printing is one of the fabric printing methods. It is to attach the fabric to the thermal transfer printing paper printed with the pattern, and press it on the heat transfer machine, and the pattern on the paper is transferred to the fabric. The outstanding advantage of this printing method is that it does not consume water and does not produce sewage. However, this method cannot print fabrics containing natural fibers such as cotton, because there is no binding force between these fabrics and dyes that can be thermally transferred. In order to realize the thermal transfer printing of fabrics such as cotton, predecessors have done a lot of research. Chinese patent 96108188 (a...
