CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

| Résumé : |
Functional polymer modified carbon black (CB) pigment (P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB) with reactive epoxy and quaternary ammonium groups was designed and prepared via a thiol‐ene click chemistry reaction, and its dispersion ability in the aqueous phase, as well as its colouring and anti‐bacterial properties for cotton fabrics, were investigated. In considering both dispersion ability and reactive ability to cotton fabric, the mole ratio of the monomers (methacrylatoethyl trimethyl ammonium chloride [DMC] and 3‐chloro‐2‐hydroxypropyl methacrylate [CHPMA]) was discussed. Morphology and chemical properties of P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB were tested by scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis and X‐ray photoelectron spectroscopy, resulting in a weight content of copolymer (DMC‐co‐CHPMA) in P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB of ca. 18%. P‐(DMC‐co‐CHPMA)‐g‐MPTS/CB was fixed onto cotton fabric via a nucleophilic‐substituted reaction between reactive epoxy groups on the CB surface and the hydroxyl groups of cotton fabric, which endowed good fastness to cotton fabric without either a fixing or an adhesive agent. Also, coloured cotton fabric demonstrated excellent anti‐bacterial activity towards Staphylococcus aureus and Escherichia coli O157:H7. |
