Abstract
A process for the treatment of a synthetic textile (T) with a cationic biocide (B) and at least one anionic polymer (P) which comprises the step of treating the synthetic textile with an aqueous composition containing the cationic biocide (B) in a concentration (c1) and containing the anionic polymer (P) in a concentration (c2), wherein the concentrations (c1) and (c2) are selected so that the ratio (R) of negative charges of the anionic polymer (P) to the positive charges of the cationic biocide (B) is between 10:1 and 1:1, leads to textiles with long term biocide activity.

Process for the treatment of a synthetic textile (T) with at least one cationic biocide (B) and at least one anionic polymer (P) which comprises the step of treating the synthetic textile with an aqueous composition containing the cationic biocide(s) (B) in a concentration (c1) and containing the anionic polymer(s) (P) in a concentration (c2), wherein the concentrations (c1) and (c2) are selected so that the ratio (R) of negative charges of the anionic polymer (P) to the positive charges of the cationic biocide (B) is between 10:1 and 1:1.
Biocide composition for the treatment of a synthetic textile (T) comprising a cationic biocide (B) and at least one anionic polymer (P), containing the cationic biocide (B) in a concentration (c1) and containing the anionic polymer(s) (P) in a concentration (c2), wherein the concentrations (c1) and (c2) are selected so that the ratio (R) of negative charges of the anionic polymer (P) to the positive charges of the cationic biocide (B) is between 10:1 and 1:1, and wherein the cationic biocide (B) and an anionic polymer (P) are homogenously distributed within the composition.
