use direct orange s is used to dye cotton and viscose fibers to obtain red, light and orange, with poor dye transfer, sensitivity to salt and good dye uptake. It is also used for direct printing of cotton and viscose fabrics, especially viscose fabrics. It can be used alone or with yellow, red, gray, brown and other colors to adjust color light and increase chromatography. It can also be used for dyeing silk, wool, vinylon, nylon and direct printing of silk fabrics.
It is used for dyeing cotton, hemp, viscose and other fabrics, and can also be used for dyeing silk, nylon, and pulp
production method using scarlet acid (5,5 '-dihydroxy -2,2'-naphthylurea -7,7 '-disulfonic acid) and aniline as raw materials, aniline is first diazozed, then coupled with scarlet acid to obtain the product, and salted out, filtered, dried and crushed to obtain the finished product.. After diazotization reaction of 19.5kg of aniline (100%), 26kg of sulfuric acid (100%), 14.5kg of sodium nitrite (100%) and 240kg of water, coupling reaction is carried out with 50.4kg of scarlet acid (100%), 26.95kg of sodium carbonate (100%), 3.91kg of sodium hydroxide (100%) and 200kg of water, and then salting out, pressure filtration and drying to obtain about 100-110kg of products.
