What are the solutions to the color bleeding of custom Pet Nonwoven printing?

Because the fiber of China Wholesale Nonwoven Fabric printing fabric is wet and contains water, the color paste will extend and bleed to the part outside the pattern due to the capillary action of the fiber, resulting in bleeding. Moisture on the rubber guide belt has not been scraped dry, causing water to penetrate into the fabric, causing bleeding. Therefore, when the spunlace non-woven fabric is printed, the fabric must be dry, and the water on the conduction belt must be scraped dry.

The viscosity of custom Pet Nonwoven printing paste should be well controlled. If the viscosity is too low, the color paste will bleed into the fabric from the edge of the pattern. According to the properties of the spunlace non-woven printing fabric, the amount of reactive dyes should be adjusted reasonably, and the amount of resist and reducing agent should be controlled properly. In addition, SYA102, a disperse spunlaced non-woven printing color enhancer, can be added before sizing. Adding it to the pre-treatment coating can increase the color yield of digital printing, so as to achieve a more uniform inkjet effect and better clarity.
