Embodiment Construction

[0016] The specific technical solutions of the present invention are further described below, so that those skilled in the art can further understand the present invention, without limiting their rights.

[0017] A kind of printing preparation method that improves printing fastness, comprises the following steps:

[0018] (1) Continuous printing:

[0019] First, mix the disperse dyes with water to fully dissolve the dyes. After filtering, add them to the evenly stirred printing paste under constant stirring, then add thickeners, wetting agents, anti-reduction agents, leveling agents, and defoamers. Warm to 20-80°C, stir quickly to fully expand the molecules in the color paste; use hot-melt dyeing method for multi-color printing.

[0020] (2) drying and color fixing:

[0021] After printing, the fabric enters the continuous drying and color-fixing integrated machine, which effectively locks the effective moisture of the dye while drying. After drying, the moisture content of ...

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...
