6In warm water or alkaline warm water, all resolve into orthophosphates and play demineralized water, heavy metal ion in chelating calcium magnesium ion and the dye liquor makes heavy metal ion etc. produce water-soluble huge legendary turtle compound, prevents that dyestuff from meeting heavy metal ion and variable color makes fabric coloured light pure simultaneously.And reduced the calcareous heat exchange efficiency decline that waits deposition to cause of dying in pusher side wall and the heat exchanger, and save production cost, prevent that fabric from abrading.
Soda ash makes dye liquor be alkalescence in dye liquor, and ultra slow dying and the washing effect, and it can remove the fabric face dirt also can remove textile loose colour, makes to dye afterwards finished product and need not reduction cleaning and can not have loose colour, and coloured light is bright-coloured.Make dye liquor smooth simultaneously, reduced fabric and dyed the machine body, abrade between fabric and the fabric and between fabric and the dye liquor, improve yield rate.
Borax plays the buffer effect in dye liquor, stablize the dye liquor pH value, makes dye liquor pH value variation minimum in the dyeing course, dyestuff is dyed, to reduce the aberration that impels each dyestuff dye-uptake to change and produce because of the variation of dye liquor pH value under the stable alkali condition.
Simultaneously above-mentioned three kinds of components are had an effect jointly in actual production and are played that peptizaiton is gentle dyes effect; Make dye liquor dye the stage pH value between 9.5-10 rising; Dye the stage pH value eventually between 9-9.5, guarantee coloration of textile materials environment pH value, improve the once successful top-quality product rate of fabric; And making even dyeing, even dyeing effect is good.
The present invention compared with prior art, it is remarkable to have a practical function, experiment product finished fabric top-quality product rate all reaches 99%, and color and luster is pure bright-coloured.Its characteristics are following:
1, alkaline assistant dyes under alkali condition and makes product color bright-coloured, and the gorgeous degree of finished product is high, has improved added value of product; Stable processing technique, it is less influenced by extraneous factors such as steam, so the cylinder difference is little, makes the finished product rate height of checking colors, and aberration is little, and coloured light is pure; Basic dyeing has cushioning effect in the absorption phase of processing, and can increase the levelling coefficient, has reduced look flower fault, makes the cloth cover even dyeing; Basic dyeing makes dye liquor smooth, reduces fabric and in dyeing course, produces scratch and fluffing, and can make the finished product cloth cover smooth, has increased the cloth cover added value; Basic dyeing can prevent that oligomer from separating out, and thoroughly eliminates cylinder bottom and stains fault, improves product high-class product rate, can make the comprehensive high-class product rate of product improve more than 5%.
2, alkaline assistant dyeing has reduced fabric and must heat up through alkali number processing poststaining and add acetic acid and carry out pickling and dye back adding soda ash and sodium hydrosulfite carries out the production process of reduction cleaning; Thereby reduced the production time and make every cylinder cloth reduce the production time more than 35 minutes, can practice thrift every day and promptly be equivalent to a cylinder cloth output in 4 hours and promptly increase output about 15%; It is poor that basic dyeing reduces cylinder; Improved the dyeing one-time success rate, thereby reduced rebuilding in the cylinder, and can thoroughly eliminate because of basic dyeing and fault such as to stain in the cylinder; Reduce return something for repairs chance and clear cylinder number of times; Product yield is improved,, makes product yield improve 29% with suitable for reading because of basic dyeing has increased the effective time
