ITOFIX VMS dyes are specifically for dyeing those troublesome deep shades where build up properties of conventional dyes is insufficient.
Our ITOFIX VMS dyes are Poly functional thus offering outstanding build up properties with high tinctorial strength giving improved reproducibility in the deep shade area and outstanding wash off properties couple this to excellent wet fastness.
In these times of ever increasing Environmental concerns the ITOFIX VMS dyes are metal free and have low effluent impact due to their very high fixation even in very deep shades.
These dyes are also suitable for dyeing by Cold Pad Batch or Continuous methods.

Fastness Test Methods
The fastness properties were tested at 1/1 standard depths.
The fastness is given for untreated undefined.
| Light Fastness | ISO 105-B02 |
| Wash Fastness | ISO 105-C02 |
| Perspiration Fastness | ISO 105-E02 |
| Water Fastness | ISO 105-E01 |
