(It is used as special additives for polyester fiber alkaline dyeing to overcome oligomers, white powder, stained spot.)
Application
Excellent polyester dyeing Auxiliary HK-2008 is a special additive for polyester fiber alkaline dyeing. It can lower comprehensive dyeing cost when uesed to alkali bath dyeing to polyester fiber and blended fabric. The special alkaline cushion dyeing and strong scattered level dyeing could avoid stained spots and color points as well as badly dyed defects that often appeared during traditional acidic dyeing. Compared to acidic dyeing, The alkaline dyeing method makes polyester fabric enjoy a much purer light, softer and smoother hand-feel.
Specifications
Appearance : Light yellow to white powder
Composition: High polymer
Ionic : Anion/non-ionic
pH value: 10±0.5(1% Aqueous solution)
Solubility: Any proportion dilute in water
Characteristics of this product
1. HK-2008 could keep the PH value of dyeing bath at about 9 in a stable condition during the whole dyeing process, which could effectively prevent and remove polyester oligomers to 90% high rate that produced in dyeing process, avoiding white powder, stained spots and color points Removal
2. HK-2008 enjoy strong level dyeing and scattering function that can overcome defects like stained spots caused by ill post-solution, avoiding pickling after T/C, T/R post-solution that makes it more suitable to make use of the “one-bath and one-step”dyeing method during pre-solution and dyeing process
3. As alkaline dyes, HK-2008 make the dyed fiber receive better effects for the dye liquor more scattered and make better level dyeing, PH value of the dyeing bath keeps stable without any influence from the amount of the dye liquor, one jar differs little from another, lofting receives high success, the finished enjoy a high color compared rate
4. As alkaline dyes, HK-2008 could shorten the time for keeping warm, less cleaning to reshape after dyeing, less times to clean jars and equipment, promote utilization of the equipment as well as save water electricity and gas.
5. As alkaline dyes, HK-2008 could reduce the cleaning process before and after dyeing. The polyester cotton blended knitted could further omit bleaching before dyeing.
6. As alkaline dyes, HK-2008 could avoid abrasion to the Knitted without soft wrinkle-free agent while dyeing. Moreover the dyed textile could be soft, smooth. Meanwhile it is easily to be washed and water-saved.
Procedure :
Methods of Application :
Aapplication levels recommended as standard are as follows:
1. 100% polyester fiber bleaching and bathing together
HK-2008 :0.5-1.0g/1
Alkali resistant and scattered dyes :X%(o.w.f)
use hot water of 90℃ to clean after dyeing then use cold water to overflow
2. Polyester-cotton bleaching and dyeing together (omit bleaching process)
HK-2008 : 0.5-1.0g/l
Hydrogen peroxide : 4-6 g/l
( Add scattered dyes 5munites after and add Hydrogen peroxide )
Alkali resistant and scattered dyes : X%(o.w.f.)
use hot water of 90℃ to clean after dyeing then use cold water
to overflow
3. Deep Colour Cotton Blended, Bleaching and Dyeing together :
HK-2008 : 0.5-1.0g/l
Alkali resistant and scattered dyes : X%(o.w.f.)
Soaping powder Floating color
Dyeing cotton by reactive dyes should take anti-staining soaping powder
2-3g/l to wash and remove floating color
Notes :
Present dyeing plants are quite adaptive to the scattered dyes with ph value of 8 or more. Please see to our technology enclosure (recommendation of scattered dyes for alkaline dyeing that are supporting to HK-2008), as Excellent polyester dyes contain dye agent that plants could use directly without modifying. But there are much uncertainties of plants, please use after test to insure smooth operation.
1. As scattered dyes are sensitive to alkali, the using amount of HK-2008 should be controlled at 0.5-1.0g/l. Please use after test for each plant holds different dye structure.
2. When producing sample, please use after blending HK-2008 to 5%, Insuring its accuracy
Storage : Store in cool and dry places with airtight condition, half year of guarantee period under room temperature.
Package : 130k/g plastic drum.
Notes: This product belongs to environmental friendly one without pollution and APEO, Non-corrosive, easily Biodegradable while can not be swallowed and needs immediate wash when touching your skin.
