A method for manufacturing an antimicrobial synthetic textile, comprising the steps of:
- a) providing a treatment solution comprising a polycarboxylic acid and a catalyst;
- b) applying the treatment solution on a synthetic textile to produce a polycarboxylic acid treated synthetic textile;
- and
- c) curing the polycarboxylic acid treated synthetic textile;
- wherein the polycarboxylic acid is one or more selected from citric acid (CA), isocitric acid (ICA), tricarballylic acid (TCA) 1,2,4-butanetricarboxylic acid (BTRCA), 1,2,3,4-butanetetracarboxylic acid (BTCA), oxalic acid, tartaric acid, succinic acid, malic acid, malonic acid, glutamic acid, aspartic acid, glutaric acid, 1,3,5-pentanetricarboxylic acid or a salt, a hydrate or an isomer thereof,
- wherein the catalyst is one or more selected from sodium hypophosphite (SHP), an SHP hydrate, monosodium phosphate (MSP), an MSP hydrate or any mixture thereof,
- characterized in that the curing is performed at a temperature ranging from 150° C. to 180° C., and
- wherein the synthetic textile is noncellulosic, optionally wherein the synthetic textile is of a polymer material having no free hydroxyl groups other than optionally up to one free hydroxyl group at each end of a polymer molecule.
A synthetic textile comprising an antimicrobial finish comprising a polycarboxylic acid cured in the presence of a catalyst,
- wherein the polycarboxylic acid is one or more selected from citric acid (CA), isocitric acid (ICA), tricarballylic acid (TCA) 1,2,4-butanetricarboxylic acid (BTRCA), 1,2,3,4-butanetetracarboxylic acid (BTCA), oxalic acid, tartaric acid, succinic acid, malic acid, malonic acid, glutamic acid, aspartic acid, glutaric acid, 1,3,5-pentanetricarboxylic acid or a salt, a hydrate or an isomer thereof,
- wherein the catalyst is one or more selected from sodium hypophosphite (SHP), a SHP hydrate, monosodium phosphate (MSP), an MSP hydrate or any mixture thereof,
- characterized in that the polycarboxylic acid is cured in the presence of the catalyst at a temperature ranging from 150° C. to 180° C., and
- wherein the synthetic textile is noncellulosic, optionally wherein the synthetic textile is of a polymer material having no free hydroxyl groups other than optionally up to one free hydroxyl group at each end of a polymer molecule.
Use of a polycarboxylic acid as an antimicrobial finish on a synthetic textile, wherein the polycarboxylic acid is one or more selected from citric acid (CA), isocitric acid (ICA), tricarballylic acid (TCA) 1,2,4-butanetricarboxylic acid (BTRCA), 1,2,3,4-butanetetracarboxylic acid (BTCA), oxalic acid, tartaric acid, succinic acid, malic acid, malonic acid, glutamic acid, aspartic acid, glutaric acid, 1,3,5-pentanetricarboxylic acid or a salt, a hydrate or an isomer thereof,
- wherein the polycarboxylic acid is cured in the presence of a catalyst, wherein the catalyst is one or more selected from sodium hypophosphite (SHP), a SHP hydrate, monosodium phosphate (MSP), an MSP hydrate or any mixture thereof,
- characterized in that the polycarboxylic acid is cured in the presence of the catalyst at a temperature ranging from 150° C. to 180° C., and
- wherein the synthetic textile is noncellulosic, optionally wherein the synthetic textile is of a polymer material having no free hydroxyl groups other than optionally up to one free hydroxyl group at each end of a polymer molecule.
