The invention discloses a
water washing and color fixing method for a Sichuan painting, belongs to the field of silk painting processes, and solves the problem of low yield caused by surface
dyeing, difficulty in cleaning, easiness in
diffusion and
pollution of a traditional Sichuan painting after
ageing. The method comprises the following steps: S1, performing high-pressure washing to primarily remove flooding, straightening four corners of the Sichuan painting silk subjected to high-temperature
ageing, enabling the front surface of the picture to face downwards, washing from any corner with flowing water, staying at the same position for 2-3 seconds, changing the position, slightly lowering the washing direction to prevent water accumulation, and increasing the washing frequency in a heavy-color area; s2,
rubbing with
clean water for the second time to remove flooding, and slightly
rubbing the picture with flowing water after high-pressure washing; s3, surface
dyeing inspection: flatly laying the kneaded silk picture in a
clean water basin, and inspecting the surface
dyeing overflow condition; s4, performing color fixation soaking, if no abnormity exists, changing clear water to reinforce a color fixation auxiliary agent, and squeezing water after soaking. The method provided by the invention has the advantages that flooding is efficiently removed,
pollution is prevented, the silk texture and picture
chromaticity firmness are guaranteed, the integrity rate of the Sichuan painting finished product is improved, large-scale production can be realized, and the service life of the product is effectively prolonged.
