Specification

| PRECID?? CORE-ALK | DYE | Alkali donor and pH regulator for reactive dyes fixation in dyeing cellulosic fibres; also suitable for setting an initial slightly alkaline pH in dyeing polyamide articles. |
| PRECID?? WC LIQ. | PRE DYE PRI FIN |
Synergic blend of non volatile organic acids with high core neutralizing power, suitable to neutralize goods after every alkaline process. Very good sequestering and anti-crystallization action, free from phosphorous and nitrogen. Neither buffers effect nor neutralizing residuals salt on the material; after a simple rinsing the product is completely removed. |
| PRECID?? AYC | DYE | Acid donor. Gradually liberates acidity as the bath temperature rises, until final pH around 3,5 – 6. Very slow dyes exhaustion rate even on polyamides with very high affinity: best migration, levelness and reproducibility, with all type of dyes in all shades. |
| PRECID?? SLA | DYE | SMELL LESS Acid donor to gradually reduce pH to 5 – 6,5 as temperature rises. Very slow dyes exhaustion rate even on polyamides with very high affinity: best migration, levelness and reproducibility. |
| PRECID?? BIO | DYE | Acid donor and pH regulator?? in dyeing cellulosic fibres |
Neutralizing action:
The pictures represents sections of cotton fibers neutralized after bleaching. It is well evident the substantial difference between a good and complete neutralizing action with PRECID WC LIQ. and a result that may cause problems during the subsequent processing.
