Abstract
A paperless transfer printing method includes the following steps: (a) printing, by a printing machine, aqueous ink onto a transfer printing temporary carrier in a set pattern, wherein a surface of the transfer printing temporary carrier is made of an elastic polymer material and a surface tension of the aqueous ink is less than the critical surface tension of the transfer printing temporary carrier; (b) drying the to-be-transferred pattern on the transfer printing temporary carrier; (c) wetting the transfer printing temporary carrier by using an aqueous surface tension increasing liquid; and (d) separating the aqueous solution or the aqueous dispersion liquid from the transfer printing temporary carrier at a tight-contact position between the transfer printing temporary carrier and the fabric, so that an aqueous ink dye is transferred onto the fiber of the fabric.
