Dye Fixing Agent

Dikofix-DFNF is eco-friendly non-formaldehyde based dye fixing agent for direct and reactive dyestuff for imparting excellent light-fastness, chloride-fastness, etc. There is no dye blending during washing.

Advantages:

• Formaldehyde free
• Improves the fastness properties and prevents dye blending
• Typical Properties of Dikofix-DFNF:
• color: Pale yellow liquid
• Odour: None
• Chemical Composition: Cationic Polymeric
• Ionic Nature: Cationic
• pH (2 % In D. W): 3.5 to 5.5
• Solid % @ 105 °C: 35 +/- 2
• Sp. Gravity @ 30 °C: 1.1000 +/- 0.0200
• Solubility: Easily miscible in water
• Shelf life: Six Months

Applications:

• Dikofix-DFNF is cationic in nature, it combines with loosely absorbed dyestuffs forming a complex molecule which is insoluble, thus reducing the bleeding tendency of such Dyeing Processes
• Generally Direct or Reactive dyed fabrics is treated with 2.50 –3.50 g / l of product DIKOFIX-DFNF
• Bleeding of colour during washing of Direct and Reactive dyed goods is a well known phenomenon mainly because of loosely held dyestuffs in the case of former and loosely held hydrolysed dyestuffs in the case of the later
• Conventional dye fixing agents generally available in market are Formaldehyde based condensation products which contain free formaldehyde
• Due to persistent demand from consumers and stringent ECO friendly restriction for exporters, a new Eco- friendly dye fixing agent which does not contain any formaldehyde is developed
• Dikofix-DFNF can be applied by padding from aqueous bath at slightly acidic pH (5.0 to 6.5) @ 13 to 40 gpl at 30 to 40 °C
• By Exhaust: Running in liquor containing 0.5-2.5 % owf, of DIKOFIX-DFNF @ 30 to 40 0C & pH 5.5 to 6.5 for 10 to 20 min
• Packing Size Availability: Dikofix-DFNF is available in 50 Kgs HDPE carboys

Other Details:

• No formaldehyde is used and hence no combined formaldehyde
• Ideally suited for fixation treatment after rinsing stage so as to reduce bleeding of Direct and Reactive dyes
• It gives much better Dye fixing results compared to normal Dye fixing Agents manufactured from Formaldehyde in relation to tone / colour change & bleeding of dyes
