Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing technology, and in particular to a flocking material that can be digitally printed. Background Technology

[0002] Electrostatic flocking is an emerging high-tech method that uses a high-voltage electrostatic field to implant short fiber flocks onto the surface of fabric or other carriers. Currently, most flocked printed products on the market are solid colors or simple combinations of only a few colors, and the patterns are relatively monotonous. The patterns are mainly created by applying glue to screen-printed colors and then implanting flocks of different colors separately. Patent application number 201810962255.4, entitled "Digital Electrostatic Flocking Printing Process," discloses a technical solution for printing on flocked surfaces via thermal sublimation transfer. However, this technical solution suffers from problems such as poor water resistance, easy detachment of the flocked fibers, and low color fastness. To solve these problems, it is necessary to develop new flocking materials that are water-resistant, have high color fastness, and are suitable for digital printing. Utility Model Content
