ABSTRACT:
This invention relates to the transfer printing of cellulosic fabric by in situ polymerization of monomers to form polyamides and polyesters. The process involves treating the fabric with a diamine or bisphenol and then treating with a diacid chloride, drying, rinsing with neutralizing agent, and then heat transfer printing the fabric after drying. The reverse procedure can also be employed in which case the fabric is treated initially with the diacid chloride.
