Garfix(Conc):Dye fixing agent for dyeings with Tie-dye technique

In recent years, the importance of handicrafts has been surged due to their cultural and financial values. The small scale industries including handicrafts can play a major role in the development of the economy of both developed and the developing countries.

Tie-dye is a modern term for a set of ancient resist-dyeing techniques. Tie-dye commonly referred to as "bandhani" from the Sanskrit root "bandh" meaning "to tie", is one of the oldest forms of surface design. The process of tie-dye typically consists of folding, twisting, pleating, or crumpling fabric or a garment and binding with string or rubber bands followed by application of dyes. The manipulations of the fabric prior to application of dye are called resists as they partially or completely prevent the applied dye from colouring the fabric. More sophisticated tie-dyes involve additional steps, including an initial application of dye prior to the resist, multiple sequential dyes and resist steps, and the use of other types of resist (stitching, stencils) and discharge.

Unlike regular resist-dyeing techniques, tie-dye is characterized by the use of bright, saturated primary colours and bold patterns. In some patterns, ties may be opened and re-tied for different dye baths. The dyers generally use the dyed thread for the tying process. This colour then becomes imprinted on the fabric, leaving coloured, rather than white, rings. After the final dye bath, the cloth is given a thorough rinsing to remove excess dye.

Several classes of dyes can be used in the tie and dye technique for cellulosic fibres, such as direct, vat, reactive and napthol. The choice of dye class used depends on factors such as there cost, ease of application and fastness properties. Reactive and Direct dyes have gained more popularity due to its cost-effectiveness, brighter shade and ease of application.

It is well-known to treat the textile after dyeing with a dye fixing agent in order to improve the wet fastness property of the dyed substrates. It is observed that fabrics treated with formaldehyde-based dye fixing agents release formaldehyde into the atmosphere directly or during processing. Due to several disadvantages of the formaldehyde-based dye fixing agents, demand for low/non-formaldehyde based fixing agents has arisen.

SAREX has developed Garfix (Conc) which is a concentrated dye fixing agent specially developed to improve wet fastness properties of fabrics dyed with direct and reactive dyes by Tie-dye technique. Due to its unique characteristics, it not only leads to excellent fixation of dyes but also prevents migration of direct dye before drying.

Unique Features:

  • Improves wash and water contact fastness
  • Improves fastness to perspiration
  • Re-matching does not require as it does not affect shade
  • Can be applied by exhaust as well as pad application
  • Compatible with cationic and non-ionic softeners
  • No adverse effect on handle of the fabric
  • Can also be applied to garments

 Recommended dosage:

Pad application

Garfix (Conc)  : 20-30g/l

Pick-up            : 65-70 %

pH                   : 5.0-5.5

Drying             : 130-170°C

Exhaust application

Garfix (Conc)   : 2-3%

pH                     : 3.5-4.0

Temperature      : 40°C

Time                  : 15-30min

  It could be seen that fabric dyed with 4% Direct Black 17B in tie-dye technique shows staining on adjacent cotton fabric during washing whereas fabric dye-fixed with 2.5% Garfix (Conc) show absolutely no staining on the adjacent fabric giving brilliant tie-dye effect.


Garfix (Conc) is concentrated dye fixing agent which not only gives excellent Tie-dye effect but also prevents migration of direct dye before drying.
