Potential of Two Synthetic Organic and Inorganic White Pigments as Substitutes for Titanium Dioxide in Textile Printing Pastes

Titanium dioxide is a pigment with the highest consumption amongst all other white and colored pigments in different industries which solely is produced from mining procedures and its consumption in Iran is thousands of tons per annum. In the present research, two new synthetic white pigments based on organic and inorganic materials were evaluated for their potential for substitution of TiO2 in white textile printing formulations. According to the results, both synthetic white pigments were capable of full substitution of TiO2 in textile printing formulations. Rubbing, washing and light fastness of printed patterns using synthetic white pigments were acceptable and inorganic white pigment showed very high stability even up to 600 oC whilst organic white pigment could only withstand temperatures of up to 190 oC.
