The Application Of Vinyl Monomers In Printing And Dyeing Wastewater And Continuous Dyeing

This article is intended for the application of vinyl monomers in printing and dyeing wastewater and continuous dyeing. The main contents are as follows:(1) The ability of the ethy copolymer and the fiber modified copolymer absorbed the Fe3+and the dye in printing and dyeing wastewater was discussed with the way of absorbance.(2) The influence of the special acrylate monomer on the color values and color fastness of continuous pad dyed polyester was investigated.(3) Choosing the best dyeing process during which disperse black ECO and black coating dyeing together.The results showed that:(1) The membranes which was polymerize with acrylic acid,acrylonitrile and N- methylol acrylamide by microwave and polyester fabric which was modified by vinyl monomers, could adsorb Fe3+in the water and the dye molecules. And they had a higher degree of Fe3+adsorption. The membranes which was polymerize 10% N- methylol acrylamide, 20% acrylic acid and 20% acrylonitrile had a adsorption with33.40%.(2) K/S and fastness of polyester fabric after dyeing had obvious improved with special acrylic acid ester monomer,and the optimum dosage was 0.4%.(3) The process factors such as binder and thickener had a influence on levelling property of the polyester/polyamide/ cotton fabric. A proper dyeing process of the polyester/ polyamide/ cotton fabric : 24 g/L black coating, disperse dye ECO 16 g/L, adhesive 10 g/L, thickener, 10 g/L L64 2 g/L, L1306 2 g/L, curing temperature 180 ℃. Before the dyeing fabric with 5 g/L XL- 90 pad a pretreatment.
