Printing preparation method for improving printing durability

Abstract

The invention provides a printing preparation method for improving the printing durability. The method comprises the steps of printing, drying and fixing, washing, dehydrating in vacuum, and drying for shaping. By adopting the method, the hot melting condition is effectively ensured, the textile has bright color, the tinctorial yield is increased by 5-30 percent, the printing durability is promoted, and the problems that polyester fabrics do not have bright hot molten printing colors or light dyeing, which trouble the printing industry for a long time, can be solved.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a printing preparation method for improving printing fastness. Background technique [0002] Printing is local dyeing. It is a process of making color paste from dyes or paints, pastes, auxiliaries and other necessary chemicals, and applying them to textiles through printing equipment to print patterns. At present, the printing equipment for polyester velvet fabrics mainly includes flat screen printing, rotary screen printing, roller printing, etc. According to incomplete statistics, flat screen printing and rotary screen printing account for 90% of the textile printing market. Conventional polyester fabric printing production line process: printed gray cloth→screen printing→drying→high temperature and high pressure steaming (or normal pressure high temperature long loop steaming)→water washing→dehydration→cloth sorting→drying and setting, except for screen p...
