Background
With the development of society, the progress of technical process and the increasing concern of people on environmental protection and sustainable development, more and more artificial fur appears on the market instead of natural fur. General artificial fur is made of polyester fiber through a complicated process, and a felt made of artificial fur belongs to one of the products. The traditional printing process of the artificial fur blanket is to manufacture a net according to required patterns, then adjust color paste, print the patterns on the blanket by the color paste in a flat screen printing or roller printing mode, then press and seep, dry, fix color and post-treat, however, the printing method has the following problems when in use: in the production process, a large amount of waste water generated by the processes of color paste preparation, screen plate cleaning, blanket washing and the like can damage the environment.
But along with the promotion of digital printing technique, more and more people utilize digital printing machine to stamp the woollen blanket, not only can reduce the production of waste water, can also promote stamp quality, stamp efficiency etc..
