Dr. Petry presented new type of neon pigments at the recently held ITMA in Barcelona. Made from minerals which occur in nature, the Pericolor Eco is a range of natural inorganic colour pigments. They can be applied in pigment dyeing of garments and textiles just as conventional synthetic colour pigments and used for garments made of cotton and cotton blends.

Pericolor Eco pigments are natural, inorganic, coloured salts and oxides. They are delivered in powder form. Depending on the used binder system they can also be applied for creating particular washing effects on garments. In contrast to conventional synthetic organic pigments, they are not based on petrochemistry. They have a high light and heat stability. The pigments are insoluble in water and resistant to chemicals, alkali and acids under usual operating conditions, said Dr. Petry in a media statement.

For good dyeing results the pieces to be dyed, made of cotton or cotton blends, should be free of preparations, sizes, or disturbing fibre accompanying substances. First of all, the ready-for-dyeing garments are precationised. The precationising is carried out on a drum washing machine with Perfixan Fdp for 20 minutes at 60 °C. After draining, the garments are rinsed. Then the dyeing liquor with the Pericolor Eco pigments is added and the pieces are treated for 20 minutes at 60 °C. After the addition of the binder Peripret Pw New the treatment is carried out for another 20 minutes.

Perfixan Fdp is a formaldehyde and heavy metal-free precationising agent for pigment dyeing in exhaust processes. The product is used for the precationising of garments. The method is especially suitable to achieve fashionable effects on ready-made pieces made of cotton and blends with cotton.

Peripret Pw New is a binder for pigment dyes, preferably applied on woven and knitted fabrics of cellulose and blends thereof with synthetic fibres. Depending on the binder quantity and the pigment concentration used, very good fastness levels can be achieved. The film of Peripret Pw New is colourless, clear, flexible and not tacky. (PC)
