Descrição

Comunicação apresentada no 20th IFATCC Congress, Weimer, Germany, 5 - 6 Maio 2005. In the present work, some specific amino compounds were linked to the cotton fabrics on a process that can impart at the same time dyeability and durable antimicrobial properties. The process was monitored on-line in a prototype dyeing system since the addition of cationic agents will influence dye uptake. Different dyeing conditions were tested with direct dyes, with and without salt, until the exhaustion curve was at least equivalent to the standard dyeing curve in the presence of salt.
