Product character

1. Sulphur blue CV is suitable for dyeing Cotton, Jeans ,Denim and so on.
2.Especially suitable for dyeing cotton, linen, viscose, vinylon and other thick fabrics dark color spectrum, simple process, easy to use, need to add antioxidants when dyeing light colors, no antioxidants when dyeing dark colors, stable color, bright color, high wetness fastness, small color difference, can improve the qualified rate of finished products.
3.The dye has a high dyeing rate on the fiber and good uniformity; However, the rate of oxidation is slower. After dyeing, the water should be washed sufficiently, so that the sulfide alkali remaining on the cloth surface is removed, the dye oxidation is accelerated, and the cloth surface is uniform. The temperature is below 70 °C, the color is dark and vivid, the temperature is too high, the color light turns gray, and the uniformity is poor.
4.When used for cotton dyeing, baking soda can be added to the rolling and dyeing solution, the amount is 10% ~ 15% of the sulfide alkali, should not be too much, otherwise the dyeing is not transparent, resulting in white core.
5.When dyeing vinylon, the color is lighter than that of dyed cotton, the color light is also dark, and the uniformity is also poor.
