Abstract

The present invention relates to a method of rendering a textile antimicrobial by treating the textile in a liquor application process with at least one amino acid and/or at least one amino acid derivative, and to a wash-durable antimicrobial textile obtained by the method.

Claim(s)

?. A method for rendering a textile antimicrobial, comprising a main process cycle comprising the steps of: – treating the textile in a main liquor application process such as padding or preferably exhaustion, the liquor of the main liquor application process comprising at least one amino acid and/or at least one amino acid derivative, – subjecting the treated textile to a heat treatment, – optionally washing the heat-treated textile, and – optionally drying the washed textile, and the method preferably comprising a secondary process cycle being performed after the steps of the main process cycle and comprising the steps of: – treating the textile using a secondary liquor application process, such as an exhaust or preferably a padding process, wherein the liquor of the secondary liquor application process comprises at least one amino acid, at least one amino acid derivative, and/or at least one antimicrobial agent; – subjecting the treated textile to a heat treatment, – optionally washing the heat-treated textile, and – optionally drying the washed textile.;
2. The method of claim ?, wherein the amino acid and/or amino acid derivative comprised in the liquor of the main and/or secondary liquor application process has an isoelectric point equal to or above 7, preferably equal to or above 8, more preferably equal to or above 8.5, and/or has a pH-independent positive charge.
