Problems solved by technology

However, there are many ecological problems in the pretreatment of this method. For example, the treatment agent used is toxic and requires a large amount of water to wash. This method will produce a lot of sewage and cause serious harm to the environment.
[0004] Wet transfer printing of some ionic dyes such as reactive dyes is also being studied and applied. The disadvantage is that a large amount of transfer paper is consumed. After printing, it is washed with water, which consumes water and produces sewage at the same time.
[0005] On the other hand, in the prior art, the printing of natural fibers, rayon and lyocell fabrics can only be cut one by one, and it is impossible to realize batch printing of the entire fabric

Abstract

The invention discloses a sublimation transfer printing process for natural fabrics or rayon. The process comprises the following steps: printing a layer of surface treating agents on cloth, and drying; and printing transfer paper coated with patterns to the cloth printed with the surface treating agents for cooling under the conditions of the temperature of 180-220 DEG C, the pressure of 6-15KG per square inch and the time of 15-20 seconds, and cooling. According to the sublimation transfer printing process, the color and the cloth are totally natural in the process of printing natural fibers, rayon and Leisel cloth, the cloth is non-tactile, is extremely soft in handfeel and vivid in effect, is just like a photo, is almost as vivid as colored rough sketch, is basically not discolored after washing and is also bright and beautiful. In the pretreatment link, only the surface treating agents are sprayed or printed, washing is not needed, only drying is needed, and any damage to the environment is avoided.

Description

【Technical field】 [0001] The invention relates to a sublimation transfer printing process of natural fabrics or rayon, belonging to the technical field of textile printing. 【Background technique】 [0002] The existing sublimation transfer printing process is: first print the pattern on the transfer paper, then press the transfer paper on the cloth with high temperature, and transfer the pattern to the cloth. The existing sublimation transfer printing at home and abroad is aimed at chemical fibers. Sublimation transfer printing is done on chemical fibers, the effect is realistic, soft to the touch, no touch, and can be perfectly integrated with the fabric. Compared with natural fibers, rayon and lyocell fabrics, it is not feasible, only pigment printing process can be used. The disadvantage of pigment printing is that it feels hard, the printing effect is unnatural, and it will fade after washing. [0003] Disperse dye transfer printing is also used for natural fibers. In o...
