Abstract
The present invention provides shaped articles incorporating mixed particulate metals comprising fine particles of a first metal or a compound thereof capable of releasing a metal ion having a first antimicrobial function, and a second metal having an ionization tendency different from that of the first metal or a compound thereof capable of releasing a metal ion having a second antimicrobial function, together with a polyester compound having specific properties, dispersed therein, and thus being capable of effectively releasing gradually over a long period a trace amount of the metal ions having an antimicrobial function from the particulate metals and maintaining an excellent antimicrobial function. The fibers according to the present invention also have excellent durability of the antimicrobial function and have excellent mildew resistance, in repeated washings and in service.
