DOUBLE-SIDED PRINTING AND DYEING OF POLYESTER FABRICS WITH DISPERSED DYES

摘要

P The present invention relates to a process for printing and double-sided dyeing of polyester fabrics with dispersed dyes. /P P This process is characterized in that the polyester fabric, as it is or previously dyed in a pastel color, is treated in an aqueous bath containing hydrophobic substances, then is dried, printed on one or both sides faces using coloring compositions based on dispersed dyes, the dye fixing on the support by heat treatment. This process gives rise to various color effects, resistant to light, to wet treatments and to rubbing, the final touch of the fabric remaining soft. /P
