Keyword: tie-dye process, dye dip method (cold staining method) will be tied up the fabric into the dye in the preparation of a good soaking period of time, stained After washing with water, solution statement, ironing. Na Futuo dyes and reactive dyes used. Na Futuo dyes and how to use technology procedure: dissolution Naphthol -> fabric padding -> air water reserve -> with Reagent -> into the fabric -> Color -> with lye - -> Caustic -> use a dry wash, the preparation of naphthol bottoming bottoming liquid prescription liquid: naphthol AS 10-15 grams of 36Be Pacific oil 15 ml 15-18 ml of caustic soda plus 1 liter of water will be colored synthetic phenol, Pacific oil mixing into the paste, then stir into the caustic soda; adding boiling water to adjust to the required amount of fluid, the liquid was not muddy sauce color is appropriate. 2, primer into the primer solution to cloth soaked for 15 minutes, remove the air to the dark place without dripping ready to use 3 Reagent Preparation: Take 10 grams of blue color salt VB, adding warm water 800 40-50 ml mix 4 will be played the end of the fabric dye color agent immersed in flip them evenly colored, about 15 minutes before 5, caustic washing the dyed fabrics immersed in alkaline solution color flip about 2 minutes after the heat water rinse, use cold water washing, drying complete. The purpose is to wash away the alkaline cleaning liquid primer left in the yellow fabric, so that the blank space clean. 10 ml of caustic soda lye prescription 36Be synthesis of 1 liter of boiled water will be tied up in fabric dyeing method into the dye pot boiling to achieve the effect of high temperature dyeing. The most common is the direct dyes and acid dyes. Dyes dissolve in water, suitable dyeing cotton, linen, rayon, silk type. Acid dye colorful, easy to spell color, and the optimum dyeing animal fibers. Direct dyes and to use technology program: dissolved dye -> Add Fabric -> boiling dye for 30 minutes -> wash dry use: prepare dyes and auxiliaries soda ash, can also be used instead of salt; to determine the weight of the fabric the use of dyes and auxiliaries, which re-dye the fabric 3% additive of 1.5% (10% salt), water 20-30 times as heavy cloth; hair with a small amount of water soluble dyes and auxiliaries, plus to requirements, and heating; to dye the fabric immersed in stirred with a bamboo stick, about 30 minutes of continuous boiling dry after washing. [email protected]### Page ###@=================steam staining to binding a good soak in the dye in the fabric before dyeing, and then into the steaming pot and fixing a certain time, often have condensation dye. Condensation is a new temporary dye deep dye, can dye cotton, hemp and other fabrics, but also dyeing wool, silk and other animal fiber. Condensation dyes and how to use technology program: warm water soluble dyes -> into fabric dyeing -> with a hair dryer dryer -> steam 6-7 minutes -> rinsing, soaping, wash -> dry iron dry water use Methods: Preparation of dyes, additives (urea), fixing agent (thiourea), baking soda; dye mix with warm water of open, join the good of urea, thiourea, etc., mix well and warm water to the required amount. Immersion dyeing about 30 seconds, flip over to make color uniformity; removed after drying with a hot hair dryer, steam 6-7 minutes (or immersed in sodium sulfide solution solidified fixing color); washing, soaping, ironing. Condensation dyes dye prescription 10-100 grams 50-100 grams urea thiourea 10-30 40-80 grams of baking soda and water, synthesis of 1 liter of sodium sulfide Kejia fixing prescription 20-100 grams of 5% sodium sulfide salt water synthesis 100-200 Ke Jia 1 liter? article transferred from: http://database.texnet.com.cn/db-technology/detail--1453.html
