The Study of the Affect Factors on Color Fastness to Crocking of Inkjet Ink

Abstract

This paper is to determine the effects of various factors on the color fastness to crocking of inkjet printing ink. Firstly, the affects of curing conditions on color fastness to crocking were discussed by altering curing temperature and curing time separately. Secondly, considering curing conditions as a constant, study the affects of the pH of ink, the amount of adhesives and the varieties of adhesives on color fastness to crocking by changing these factors respectively. The results show that: the color fastness to crocking of printing fabric is better when curing temperature is 1800C and curing time is 90s; the wet crocking fastness of printing fabric declined as the pH of ink increased; the color fastness to crocking of fabric printed with ink which prepared use water-based polyurethane is better than use water-based polyacrylate.
