Naphthol Dyes comprise phenols that offer solubility in alkaline solution and is substantive to cotton especially in presence of salt. These small molecules come with low to moderate substantivity but have properties of rapid diffusion into fibers. The higher substantivity also helps in achieving better rubbing fastness due to less AZO pigment formation on fiber surfaces.

Features :

• As naphtholate ions are coplanar with elongated molecular structures, these work as colorless, low molecular weight direct dyes
• When used in combination with bases, these provide for achieving large number of shades including red, maroon, brown, yellow, orange, blue, black
• Superior dyeing possesses with good light fastness
• Can also be produced on viscose & jute
• With modifications, it can also be used for nylon, silk, wool, polyester fibers
• Can be supplied through different methods like jigger, padding, tub-dip, open beck, circulating and others

Specifications :

• Available in micro pulverized form
• Dyes are water insoluble and contain simple water soluble diluents
• Are highly alkaline with pH of approximately 12-14
