Pigment printing

Pigments. Pigment-printed textiles represent the highest percentage of all printed textiles, accounting for between 40 and 50% of all ceUulose and over 90% of polyester—cotton blend prints. This is primarily the result of the uncompHcated process, low cost of imparting colored patterns to textiles with pigment systems, and theh appHcabiHty to all fibers. 

The use of disperse—reactive dye combinations is popular for printing polyester—viscose blends for fashion fabrics where the drape, handle, and general aesthetic quaUties of such fabrics are adversely affected by pigment printing.

The textiles printing industry has an appreciable interest in P.Y.17 and applies it in the form of pigment preparations. Where its fastness properties satisfy the specifications and where the use requirements are not too demanding, the pigment is also utilized for spin dyeing purposes. Manufacturer recommendations include media such as polyacrylonitrile and cellulose acetate fibers, on which 1/3 SD pigment prints exhibit a lightfastness which is equal to step 5 on the Blue Scale.

In pigment printing the dyestuff pigments are bound to the textile by means of a polymer binder system and no additional washing is performed however, wastewater is released from the cleaning of the equipment and machinery. 

The concept of microfabrication on powder surfaces can be used in many industrial fields, e.g., in pigments, printing inks, paints, foods, pharmaceuticals, detergents, cosmetics, dental materials, implant materials, copy toners, ceramics, cements, electrorheological materials, and metallurgy, etc. (I). 

Blends of polyesterand cellulosic fibers are printed with disperse and reactive dyes only in cases, when pigment printing is unsatisfactory. Dye selection follows basically the rules given for continuous dyeing polyester and cellulose fibers. 

Pigment padding and pigment printing techniques are becoming increasingly popular throughout the world (1, 2,1,4).

The same catalyst system was also used in the pigment print paste of an oil-in-water emulsion system. It also promotes curing with a minimum use of energy. Prints are fixed by mild curing on drying cans at 95-100°C for 1-1.5 minutes instead of conventional curing at 150-160°C for 3-4 minutes.
