DYAN ATP finds useful applications in almost all areas where it is helpful to even the strike rate of acid dyes without adding a strong retarder. This includes carpets, hosiery, knits and wovens in equipment ranging from becks to jigs.

DYAN ATP is a completely nonionic product, designed especially to prevent the premature or cold fixation of dyestuffs on type 6 Nylon during continuous operations. The main problem in continuous processing the deeper dyeing nylons, such as Type 6, is that they preferentially absorb the dye out of a pad bath, and this leads to shade changes during the course of a run, and tailing-out.
DYAN ATP is most effective in preventing this preferential absorption and tailing-out on any continuous process such as Kuster pad, slop pad, space dye application, etc. The use of 3 - 10 g/l DYAN ATP is sufficient to prevent these conditions.

By preventing the premature fixation of dyestuffs, DYAN ATP allows many styling opportunities, and in many cases will allow the dyer to handle type 6 Nylon as easily as type 6,6. This is especially noted in the gum-TAK area of carpet dyeing. The usage levels in this type of application range from 2 - 20 g/l DYAN ATP, depending on the desired results.

DYAN ATP also has the unique advantage of eliminating crocking when heavy shades are continuously dyed on type 6 or 6,6 yarns. It prevents the dyes from striking on the tips of the loop or pile, thus letting them penetrate down into the carpet to the root of the loop or pile and giving a completely level shade; this is particularly useful when Acid Red 151 is used. Normally, 1 - 2 g/l of DYAN ATP in the pad bath will eliminate crocking.

Another feature of DYAN ATP is the fact that it has anti- precipitation characteristics, and can be used in both batch and continuous operations for this purpose, the usage level ranging from 0.5 to 1% in normal work.

The QUALITY of DYAN ATP is monitored by DyeTech, Inc.'s quality system, which has been certified to meet the ISO9001 internationally recognized quality standard.
