Transfer-printing method for polyester-based fibrous materials

Abstract

Provided is a transfer-printing method for polyester-based fibrous materials, which requires a small number of steps, which achieves a low fixed cost and a low variable cost, in which a waste water load is small, and with which an excellent-quality transfer-printed product of a polyester-based fibrous material is obtained, the method being characterized by performing transfer printing through bringing, into close contact with a polyester-based fibrous material, and through pressurizing and heating a transfer-printing paper product obtained by performing printing, by using a non-sublimable disperse dye ink, on a transfer-printing paper sheet obtained by providing, to a base-paper sheet, a sizing agent having a functional group selected from the group consisting of an acidic group, an ester,an ether, an amide, an alkaline metal salt, or an alkaline earth metal salt of the acidic group, and a cationic group, or a sizing agent which is selected from a natural gum glue, a cellulose derivative, and a polysaccharide, and in which a carboxylic acid compound is further blended.

Description

technical field [0001] The present invention relates to a transfer printing method of polyester fiber materials using non-sublimation type disperse dyes. Background technique [0002] As methods of printing patterns on polyester fiber materials with disperse dyes, screen printing, roll printing, and rotary screen printing using color pastes of disperse dyes are known and practiced industrially. However, these plate-making printing methods have poor design performance, are not suitable for small batches and short delivery times because of the need for plate making, and need to make excess color paste because of the use of a large amount of color paste, so the drainage load is large, and the operation process is many. It is complicated, requires skilled operation for fine coloring, mold clamping, etc., and the incidence of defective products tends to increase, and there are many problems.

AI Technical Summary

Problems solved by technology

However, this method has the following problems: the cost of the release paper (transfer base paper) is high, and if the humidity of the factory where the transfer is performed, the storage conditions of the transfer printing paper, etc. are not suitable, 100% of the transfer ink cannot be accepted. layer, it will produce defective products, it is also difficult to recycle paper, and the number of processes is large, etc.

However, this method requires a pretreatment process of fiber materials, a printing process, a steam treatment process, and a soaping process, and the number of processes and drainage load are large, and there are problems in terms of economy and quality stability.
