Crosslinking agent for pigment printing & oil and water repellents

摘要

TEXTILE printing is the branch of textile wet processing industry and is becoming increasingly popular for all fibres and varieties of fabrics as well as garments. Printing of cellulosic fibres are considered to account for more than 70% of all printed substrates and pigment printing is a major method. The use of pigments for printing of textile products has dramatically increased over the last 50 years. Pigments are used to produce printed products for a number of end use including apparels, home furnishing, crafts and nonwoven articles. Over 18 billion liners yards of printed fabric produced worldwide each year, about 50% of this yardage is pigment printed. Pigments are substance in particular forms. They are essentially insoluble in the media into which they are incorporated and are mechanically dispersed in order to modify the colour and light scattering properties of such media. Ancient Chinese used pigments for colouring textile by the block pigment printing method. Pigment printing was on rise in the 18th century however it met with limited success due to inadequacy of the binder as a fixing agent for pigment on the fabric and relatively poor pigment dispersion available at that time.
