Abstract

Zeolite particles retaining antibacterial metal ion, such as Ag, Cu or Zn ion, at ion-exchangeable sites of the zeolite are included in a low-melting component of conjugated fibers which comprise a low-melting component and a high-melting component. Upon heating, the low-melting component spreads to cause more zeolite particles to be exposed, which yields higher antibacterial activity in a fiber article produced from the conjugated fibers.
