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.

Viscose fiber is also called artificial cotton, is a kind of regenerated cellulose fiber, natural cellulose as raw material by wet spinning and made, with skin core structure, because of its excellent properties, widely used in dyeing and finishing industry, especially active in the printing process, the products are deeply welcomed by consumers. While the reactive turquoise blue dye due to its special copper phthalocyanine dye molecule structure, makes more difficult diffusion into the fiber, light and color printing fabric wilt. So the stamp is needed when the amounts of urea to moisture to help dissolve, help dye dissolution. Urea containing nitrogen rich, in recent years, with the improvement of people's consciousness of environmental protection of the earth, as causing water pollution (eutrophication) material, namely the nitrogen, the phosphorus compounds, reduce its consumption has become an important research topic in the dyeing and finishing industry. At the same time, the traditional printing methods using steam fixation, because when steaming water supply, the demand for auxiliaries is not high, we can achieve the dyeing effect is good. But the steam fixation requires a very long time, usually for half an hour, energy consumption is very large. In the current global resource shortage situation, everyone started, as far as possible to reduce energy consumption, saving resources, to the enterprise sustainable development from personal road, the new direction is the development of printing and dyeing industry. So this paper is how to reduce urea reactive turquoise blue K-GL dye printing process of artificial cotton in the amount of exploration, printing methods curing fixation, shorter fixation time (30min → 130s), reducing energy consumption, saving resources. In the experiment we will look for a series of environmental protection urea alternative or adjuvant, to add to the printing paste, while the corresponding reduction in the amount of urea, printing effect is different, to find the best formula is printing effect, we explore the purpose.
