Abstract
A liquid and stain-resistant antimicrobial fabric is provided that can withstand the high temperatures required for transfer printing. A coating composition comprising a copolymer composition, an antimicrobial agent and a fluorochemical composition is applied to fabric such as polyester, to produce the coated fabric. The liquid and stain-resistant, antimicrobial, printed fabric retains its natural texture, is durable and easy to handle.
