A P Industries apazol Reactive AS/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.

A P Industries apazol Reactive AS/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 600C
  • Possible to produce deepest shades
  • Very much economical for medium and dark shades
  • Excellent shade build-up
  • Excellent solubility in water
  • Excellent leveling characteristics
  • Least sensitivity to variation in dyeing conditions

Exhaust Dyeing Method

Winch/Soft flow jet dyeing : Start dyeing with required amount of dyes at room temperature. Run the fabric for 10 minutes. Add the required amount of salt in 2-3 portions over a period of 20 minutes and raise the temperature to 600C in 20-30 minutes.

Washing Off

To achieve best possible fastness properties,it is essential to remove the unfix / 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 non-ionic or anionic 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 standard test methods at 1/1 std. depth, mentioned below:

Washing ISO-3 and ISO-4 (Ratings by greyscale : 1-poor, 5-excellent).
Rubbing ISO 105x12 (Ratings by greyscale : 1-poor, 5-excellent).
Light AATC 16E 20hrs. (for blacks at 8.0% shade)(Color change ratings by greyscale:1-poor, 5-excellent).
Perspiration ISO 105-E04 (Ratings by greyscale:1-poor,5-excellent).
Chlorinated Water ISO 105-E03 (Ratings by greyscale:1-poor,5-excellent).
Post Mercerisation 300 g/l caustic soda solution at 200C for 5 min. Followed by cold rising 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.
