Pigments for printing continue to excel in the field of colorants due to ease of application on various substrates, meet the demands of fastness properties, regulatory impact/compliance etc and make inroads into new applications like inkjet printing. Colour components in the past were known as pigment emulsions owing to the medium of kerosene emulsion thickening used and later they became pigment dispersions, which transpire now as pigmented or digital inks for textiles abroad.
Understanding the basic concepts provide clarity of the subject and dispel misconceptions thereby forming a sound base for emerging technologies effecting value addition to the downstream users. Thus, it is worthwhile to cover pigment printing system in the curriculum of the educational institutions for virtual learning.
Pigment printing constitutes about 50% share and therefore it is appropriate for an exclusive presentation on this theme to enable users recapitulate the various components used, like color pigment dispersions, binders, fixers, thickeners, rheology modifiers, auxiliaries (emulsifiers and softeners) and their functions.
This bears testimony to the talk of Dr.S.Y.Kamat, Chief Marketing, Pidilite Industries Limited on “Pigment Printing of Textiles” in the K.H.Kabbur Commemorative Lectureship organized by the Dyestuff Technology Department of Institute of Chemical Technology on 4th February 2010 in K.Venkataraman Auditorium, attended by the industry executives, faculty members and students. Dr.N.Sekhar proposed vote of thanks.
Building bonds for 50 years, Pidilite introduced pigment dispersions in early 60's in India and FEVICOL brand adhesive enjoys lion's share of market and with the right kind of advertising the company thrives in its sales. Similarly, Pigment dispersions (TEXCRON), Binders (PIDICRYL), Synthetic thickeners (PIDIPRINT), Fixing agents (PIDIFIX) and Rheology modifiers have been developed for optimal application in printing of textiles.
