Dianix Red SE 3B - Reference Information
| Introduction | disperse red 343 is a kind of disperse dye with bright color and excellent fastness, which is suitable for dyeing polyester fiber. Because the dye has two cyanide radicals, the color light is bright, the color giving amount is high, and the affinity to the fiber is high, so it is suitable for ultrafine fiber dyeing. |
| Application | disperse red 343 is an azo disperse dye, which can be used for dyeing polyester and its blended fabrics, suitable for carrier method, high temperature and high pressure method and hot melt method dyeing, can also be used for printing of polyester, acetate fiber, triacetate fiber, permanent pressing finishing. The dye has bright color, good levelness, various fastness, especially sublimation fastness and washing fastness, which are better than the disperse red FB commonly used at present, and the amount of three wastes is small and easy to handle. |
| Application example | CN201810579216.6 discloses a colorant for polyester fabric transfer printing paper and its production process, including the following mass fraction of components: disperse red 343#, disperse red 92#, diffusing agent, levelling agent, anti-migration agent, the colorant production process, including (1) in the jar to add cold water;(2) add the above dose of levelling agent, anti-migration agent;(3) adjust Ph with glacial acetic acid;(4) after the first temperature rise, add the above dose of disperse red 343#, disperse red 92#, diffusion agent and maintain;(5) the temperature rise was continued and maintained, and then the color matching was performed. |
| preparation | in A ml flask, add 10.6g of Intermediate A, Intermediate B, toluene 40g, water 15.2g, dodecyltrimethylammonium bromide 0.15g, copper salt catalyst 0.01g, cyanohydrin 3.22g, several g of sorbent, TLC detection at 120 ℃, the reaction was finished, filtered, washed and desalted, then washed, the product was obtained in 7.63g with a yield of 91%. |
| Use | is suitable for dyeing polyester fiber, especially suitable for dyeing Ultrafine fibers |
