(6) the printing paper formed by the stamping of one printing roller is stretched by the tension applied by a far-end winding device and is operated by a transmission device of the printing roller, and the printing paper is driven by the tension generated by the next printing roller to operate and separate from the printing roller in the operation process;
(7) and (4) applying the transfer printing paper printed with the patterns obtained in the step (6) to printing and dyeing of fabrics.
In the step (1), the patterns are non-pure color stripes or lattice patterns.
In the step (2), the vibration of the graver and the surface of the rotating roller move relatively to generate a triangular motion track to form a diamond-shaped mesh of the inverted square cone.
In the step (2), the lattice pattern is carved according to a normal carving process, the edge of the normal pattern position is expanded and carved, the expansion distance is 1cm, the depth of the expansion position is shallow, and the color generated on the printing paper and the color of other pattern positions can be ignored after being pressed; the expansion area forms a transition area between the normal pattern position and the non-pattern position, and the phenomenon that a scraper generates a cutter jumping mark due to the rapid change of a plane when a plate roller runs in the production process is prevented.
In the step (2), the depth of the mesh at the normal pattern position is 45-60 microns, the depth of the mesh in the expansion area is 5-10 microns, the number of engraved mesh lines is 48-60 lines/cm, and the engraving angle is 130-145 degrees.
In the step (3), the dye comprises one or a mixture of more of disperse red 60, disperse yellow 54, disperse yellow 60, disperse blue 72, disperse blue 359 and disperse black; the alcohol is one or more of methanol, ethanol, propanol, isopropanol and isobutanol; the auxiliary agent comprises one or more of wetting agent, defoaming agent, stabilizer, flame retardant, antistatic agent and filler.
In the step (3), the viscosity of the slurry is 17-21 s.
The beneficial technical effects of the invention are as follows:
the process can effectively improve the jumping knife mark of the printing roller in the transfer printing process. The angle of the scraper is adjusted, the angle is reduced, the contact area between a knife edge and the printing roller is increased, the phenomenon that a jump knife mark is formed due to strong fluctuation generated at the connection part of the pattern of the printing roller with an overlarge angle is reduced, and when a copper roller is engraved by a normal electric engraving knife, the set data is engraved to form a continuous, compact and regular small mesh. Obvious at the connection part with or without patterns. The engraved cells protrude at the edge positions. On the basis, the novel process is characterized in that 1cm is expanded at the outer edge to serve as a transition area during pattern design, and carving holes in the transition area are small, so that color cannot be generated or is light to be negligible. The transition area can effectively relieve the situation that the pressure of the doctor blade is rapidly changed at the pattern connection position during production.
According to the invention, through specific operation processes of pattern design, roller plate engraving, slurry preparation, transfer printing and the like, the problem of no jump cutter mark of a final product is solved.
