Cold transfer printing method for viscose fabric

Abstract

The invention discloses a cold transfer printing method for a viscose fabric, which comprises the steps that the viscose fabric and a piece of transfer printing paper enter an interlayer where an annular blanket zone is contacted with a main pressure roller in a transfer printing device; under the action of five compression rollers and the main pressure roller, a dye pattern on the piece of transfer printing paper is transferred onto the viscose fabric; and the pressure of the five compression rollers are set to be 200 kg, 500 kg, 1,000 kg, 2,000 kg and 3,500 kg in sequence. According to the cold transfer printing method, a manner of increasing transfer printing pressure in sections is adopted for the five compression rollers in the transfer printing device, and optimal pressure values are obtained respectively through repeated experiments, therefore, free moisture on the viscose fabric can be extruded out by times in the cold transfer printing process, color paste on the piece of printing paper is moistened sufficiently and absorbs the moisture, further, the permeation on the back side of the fabric is reduced greatly, a flower pattern on the front side of the fabric is prevented from diffusion, and the transfer printing effect is not influenced.

Description

technical field [0001] The invention relates to a cold transfer printing method, in particular to a cold transfer printing method for viscose fabrics. Background technique [0002] At present, the device used in cold transfer printing is mainly the transfer printing device of Shanghai Changsheng Textile Products Co., Ltd., that is, the transfer printing device of the cold transfer printing machine disclosed in Chinese patent document CN201669968U. [0003] The device is mainly composed of a main pressure roller, five pressure rollers, four support rollers, front guide rollers, rear guide rollers and an endless blanket belt. The method of using this device for cold transfer printing is as follows: the printed fabric sent from the cloth feeding mechanism and the transfer printing paper sent from the paper feeding mechanism are closely bonded before the transfer device of the cold transfer printing machine, and enter the ring through the front guide roller. The interlayer of t...

Problems solved by technology

[0005] It is not a big problem to use this device for cold transfer printing on some natural fiber fabrics such as cotton fabrics, but when cold transfer printing is performed on viscose fiber fabrics, it is easy to cause the background of the fabric to permeate and the front of the fabric to permeate, thus affecting the product. quality
