ITOVAT dyes applied on cellulosic fabrics such as cotton or linen show outstanding fastness characteristics.
ITOVAT dyes are especially suitable for home furnishings, work wear and service uniforms as well as for parasol and tenting textiles.
ITOVAT dyes can be separated into three different classes all with individual dyeing characteristics dependant upon dyeing temperature, vatting method and salt, caustic and hydrosulphite levels.

Fastness Test Methods
The fastness properties were tested at 1/1 standard depths.
The fastness is given for untreated undefined.
| Light Fastness | |
| Wash Fastness | |
| Peroxide Bleaching | |
| Hypochlorite Bleaching |
The fastness properties were tested at 1/1 standard depths.
The fastness is given for untreated wool.
