Blenching And Dyeing Of Camel Hair Material

Camel is a good textile raw materials. But now, as camel hair with deep brown itself,can only be processed into textiles dyed natural light tan or dark, resulting in a singlespecies, color and monotonous. Thus in bleaching and dyeing the camel hair processing,colorful dyed the color of the product to broaden the use of camel hair, meet consumerdemand, are of great significance.The subject of camel hair dye decolorization and a preliminary study. The difficultylies in camel hair bleaching are protein fibers, cellulose fibers in the traditional bleachingprocess is carried out under alkaline conditions. camel hair decolorization using the firstpart of our heavy metal ions and complex re-oxidation of pigment bleaching method.Through the process conditions of temperature, time, pH, hydrogen peroxide concentrationin the analysis of comparative experiments, as well as the products of the program to makewhiteness, strength of comparative analysis, to find a more ideal bleaching process，In theweak acid condition of camel hair decolorization treatment with hydrogen peroxide. Thecamel can achieve higher brightness, but will also of camel hair fiber strength damagecontrol in a smaller range. better conditions for the bleaching liquor ratio1:40,decolorization time4h, bleaching temperature40℃, hydrogen peroxide concentration of8g/L, oxygen bleaching stabilizer sodium pyrophosphate concentration of6g/L, bleachingpH6.5.In the dyeing process, we use the Lanasol dyes are a class of brominated acrylamideactive group reactive dyes for wool, and its ability to respond with high, bright color, thecolor fastness. We use two-step two-bath dip, respectively, discussed the concentration ofsodium carbonate alkaline agent, dyeing temperature, dyeing time, fixation temperature,fixation time, pH value of camel hair dyeing properties, the apparent color of the dyedcamel hair volume and tested for color fastness. Final results showed that: Optimumdyeing conditions for the concentration of sodium carbonate alkaline agent20g/L, dyeingtime60min, dyeing temperature80℃, fixing the time30min, fixing temperature80℃,pH6.
