Therefore, new materials and new technologies are also in progress in the textile field. For example, the fabric with ecological perception function is obtained by dyeing the fabric with plant pigment, but similar technical application and product development often have the defects of single product color and low fastness. Therefore, on the premise of ensuring that the lac pigment is used as a functional material for textile printing to endow the textile with a clean visual function, the defects of single color, single pattern and low fastness are effectively overcome, and a wider choice is provided for the application of the technology, so that the method is a good research direction. And the research direction also lays a foundation for similar technical application in the future.

The shell fabric has a clean visual function by utilizing the lac pigment through a printing process, and four processes of single color, single pattern and low fastness of the lac pigment can be solved to different degrees, wherein firstly, the lac pigment paste and the reactive dye paste are mixed for printing; secondly, performing full-color printing on the cellulose fabric by using the lac pigment paste, and performing color register printing on the fabric subjected to the lac pigment printing by using the active paste; thirdly, performing full-color printing on the cellulose fabric by using an active thickener, and performing color register printing on the actively printed fabric by using a shellac pigment thickener; fourthly, dyeing the cellulose fabric by using the reactive dye, and then carrying out chromatography printing on the fabric dyed with the reactive dye by using the lac pigment paste. In order to enable the development of the fabric with the clean visual function to be more diverse and practical, the process which has the clean visual function, can obtain various colors, various patterns and higher fastness is imperative through experimental design and sample test, and the invention also provides guarantee for the industrial production of the shellac pigment printing fabric.
