In this paper,Viscose fiber is also called artificial cotton, is a kind of regenerated cellulose fiber, natural fiber as raw materials by wet spinning, with skin core layer structure, active cui LAN structure because of its special copper phthalocyanine dyes, lead to dye molecules diffusion within the fiber is more difficult, withering printed fabric color light and color. So it is difficult to dye diffusion penetration, printing need a lot of urea to hygroscopic help dissolve, help dissolve dye. As the earth's environmental protection consciousness enhancement, as a result, water pollution, eutrophication of material namely, nitrogen and phosphorus compounds, to reduce their consumption have become the subjects of dyeing and finishing industry. This article on how to reduce artificial cotton reactive cui LAN K - the amount of urea in the GL dye printing process to explore.
