ANTIBACTERIAL COMPOSITION, ANTIBACTERIAL POLYESTER FIBER, AND PROCESS FOR PRODUCTION OF ANTIBACTERIAL POLYESTER FIBER

WIPO Patent Application WO/2010/143317

A1

Disclosed is an antibacterial composition which has good dispersibility in water and can significantly reduce the occurrence of the yellow discoloration of a base material or the like which is subjected to an antibacterial treatment. The antibacterial composition comprises a polyester resin and a silver-containing antibacterial agent, wherein the polyester resin is produced by the reaction between polymerizable components comprising at least one of a terephthalic acid component and an isophthalic acid component as a carboxylic acid component and at least one polyalkylene glycol as a glycol component.  In the antibacterial composition, the polyester resin has a segment derived from the polyalkylene glycol.  Therefore, the antibacterial composition has excellent dispersibility in water, and an aqueous dispersion containing the antibacterial composition can be prepared readily.  Further, when an antibacterial treatment of a base material or the like is carried out by using the antibacterial composition, the yellow discoloration of the base material or the like can be reduced significantly.
