Problems solved by technology

The above-mentioned process method has two disadvantages: on the one hand, it increases the workload of subsequent fabric washing and increases the discharge of printing and dyeing industrial wastewater; on the other hand, it is difficult to control the degree of wetting of various fabrics, making the dye The transfer stability is not good. If the fabric is wetted, the pattern will be blurred. If the fabric is not wet enough, the color will be too light.

Abstract

The invention discloses dry heat transfer printing paper and a preparation method thereof for textiles. The method includes preparing viscous fluid with a solid content of 2-10% w / w from a high polymer thickener and a water-soluble hot melt adhesive according to a mass ratio of (1:5)-(5:1); adding assistants such as acid, alkali, an absorbent and a fixing agent into the viscous fluid according to categories of fabric and dye so as to produce a transfer substrate; and subjecting the transfer substrate to coating, drying and press polishing processing for the paper to obtain the dry heat transfer printing paper for the textiles. The paper can generate strong adhesive force on the surface under a certain temperature and pressure and can be tightly attached to the fabric. If the paper is used for printing of non-thermoplastic fabric, modified or dewing treatment is not required any more before the printing, transfer printing can be directly performed on dry-state fabric, the dye transfer stability is guaranteed, and clean and high-quality printed patterns can be obtained; and simultaneously, the processing time is shortened, waste water emission of the printing and dyeing industry is reduced, and energy saving and environment protection are facilitated.

Description

technical field [0001] The invention relates to a dry heat transfer printing paper and a preparation method thereof, belonging to the technical field of textile printing processing. Background technique [0002] The earliest dry heat transfer printing paper for textiles is widely used in the printing of polyester fabrics. This kind of printing is the well-known disperse dye sublimation transfer printing. Under high temperature and pressure, the pattern is transferred to the fabric by sublimation of disperse dyes. This printing method has the advantages of clear layers of printing patterns, strong three-dimensional effect, short process flow and strong processing flexibility. Once it came out, it attracted wide attention from people in the industry. [0003] Yet above-mentioned method is only suitable for the synthetic fiber fabrics that have thermoplasticity such as dacron, is not suitable for fabrics such as cotton, real silk. The early method is to modify the surface of ...
