料インキの安定性に問題があり、新しいプロセス
の開発が望まれている。 This sublimation transfer printing method has advantages such as ease of processing, reproducibility of patterns, and non-pollution, but problems remain with the depth of dyed color and texture. However, the biggest drawback is that it is not sufficiently adaptable to natural fibers and their blends. As a technique corresponding to these, methods have been used so far in which fibers are pretreated or modified and then transfer printed, but the dyeing process is complicated and has not been put into practical use much. On the other hand, there is a wet transfer printing method as a transfer method that does not pre-treat or modify the fibers, which involves humidifying the fibers in advance, transferring by sandwiching a moist cloth, or decomposing the fibers during transfer. However, there are problems with controlling the amount of water and the stability of the dye ink, and the development of a new process is desired.

In order to actually make a transfer medium for dye ink, knitted fabrics, nonwoven fabrics, or porous polymer sheets are impregnated or coated with a 20 to 50% by weight aqueous solution of polyvinyl methyl ether, and then gamma rays or electron beams are irradiated. By crosslinking polyvinyl methyl ether, a sheet-like transfer medium made of a crosslinked gel of polyvinyl methyl ether can be obtained. This transfer medium absorbs water below 30°C and
Releases water above ℃. To perform transfer printing using this, first, the transfer medium is immersed in water at 30°C or higher to allow the gel to absorb water. Next, the absorbed water is removed from the surface of the transfer medium, and a pattern is printed on it using dye ink.Then, the printed transfer medium and the cloth to be printed are placed on top of each other, and heated to a temperature of 40°C or higher. Since the gel making up the transfer medium releases water, the dye in the transfer medium is transferred to the fabric. In this case, instead of printing directly on the transfer medium, a porous membrane, a highly smooth and thin non-woven fabric is printed on, the transfer medium is overlapped, and this is brought into contact with the cloth to be printed. Transfer can also be effected by heating to temperatures above .degree. The transferred cloth is
If necessary, post-treatments such as dry heat treatment and steaming are performed to completely fix the dye.
