NILACOLOR AFFINITYXTRA

GLOBAL PROCESS FOR POLYAMIDE DYEING

1 PRE-TREATMENT

NILACOLOR AFFINITYXTRA reduction of the stripes caused by the stretching difference during yarn processing of polyamide fiber.

DYEWET SPA LEDIGAL PA

The differences of affinity in polyamide fiber mainly caused by stretching difference after extrusion during the yarn production produce the kinetic stripe. This difference is very noticeable according the type of dyes used. For instance, turquoise and pre-metallized, which have got lower mobili-ty of the molecules of the dye, give bad migration and consequently bad leveling effect.

Because of this, the NILACOLOR AFFINITYXTRA process starts with a pre-wash before dying, in order to modify the surface of the fiber and to reo-rient it in a way that gives a greater mobility of the molecules of the dye.

NILACOLOR AFFINITYXTRA substantially improves the leveling effect, even when using a combination of dyes with very different exhaustion curves. This process is very suitable for polyamide dyeing in cross-bobbin and also for the other types of dyeing systems.

With NILACOLOR AFFINITYXTRA the best results can be achieved for swim-ming wear, which have to fulfill requirements like fastness to chlorine, ye-llowing, sea water, hard water, alkali and acid sweat, etc., without using dyes or/and processes much more costly.
