Inkjet printing process of cotton fabric
A technology of inkjet printing and cotton fabric, which is applied to plant fibers, textiles, papermaking, and dry-cleaning fiber products. It can solve the problems of insufficient color depth of inkjet printing, limit the development of inkjet printing, and large color difference of electronic patterns. Appropriate color depth, enhanced washing resistance and absorption rate, not easy to fade
