Chemifix S/W Dyes

Chemifix S/W Dyes are High Performance dyes, made from speciality dyestuff intermediates and reactive groups. These dyes are specially engineered to give very high tinctorial value and therefore can be used for producing deep shades by exhaust dyeing.

Chemifix S/W Dyes can also be used in combination with regular VS or ME Dyes for producing mixture shades.

Salient Features

  • Suitable for exhaust dyeing at 60° C
  • Possible to produce deepest shades
  • Very much economical for medium and dark shades
  • Excellent shade build-up
  • Excellent solubility in water
  • Excellent levelling characteristics
  • Least sensitivity to variation in dyeing conditions
  • Very good fastness to washing, rubbing and light

Exhaust Dyeing Method

Winch/Soft Jet Dyeing

Start dyeing with required amount of dye at room temperature. Run the fabric for 10 min. Add the required amount of salt in 2-3 portions over a period of 20 min. and raise the temperature to 60 C in 20-30 min. time. Continue dyeing at 60 C for 15-30 min. Add Alkali in 2-3 portions over a period of 20 min. and continue dyeing for 60-90 min.

Salt and Alkali requirement

Washing off

To achieve best possible fastness properties. it is essential to remove the unfixed/hydrolysed dye completely from the substrate. Following sequence can be used for this purpose:

Cold rinse -------> Hot rinse -------> Neutralise (with acetic acid) -------> Soap (1-3 times) -------> Hot rinse -------> Cold rinse.

Soaping can be done with 1-2 g/l anionic or non-ionic detergent or polymeric washing off agent at boil for 15 min. (M:L::1:15 to 1:20)

Fastness Properties

Fastness of dyed material to various agencies was assessed as per the standard test methods at 1/1 std. depth, mentioned below:

  1. Washing: ISO-3 and ISO-4 (Ratings by greyscale: 1 - poor, 5 - excellent)
  2. Rubbing: ISO 105 x 12 (Ratings by greyscale: 1 - poor, 5 - excellent)
  3. Light: AATCC 16E 20 hrs. (for blacks at 8.0% shade)(Color change ratins by greyscale: 1 - poor, 5 - excellent)
  4. Perspiration: ISO 105-E04 (Ratings by greyscale: 1 - poor, 5 - excellent)
  5. Chlorinated Water: ISO 105-E03 (Ratings by greyscale: 1 - poor, 5 - excellent)
  6. Post Mercerisation: 300 g/l caustic soda solution at 20 C for 5 min. Followed by cold rinsing and neutralization with sulfuric acid. (Ratings by greyscale: 1 - poor, 5 - excellent)

Note:1

Since post mercerization results are more sensitive to processing conditions/ sequence, the data mentioned in this shade card is only indicative, without any guarantee/ assurance.

Note:2

Standard depth was determined by using 40S mercerised poplin fabric, M:L::1:10, common salt:60gpl, soda ash : 20gpl : Dyeing time : 90 min.
