Synthetic zeolite is stabilized to water by soaking it in a buffered acid solution for a prolonged time. The stabilized synthetic zeolite does not exhibit alkalinity when it is dispersed in water at room temperature for 24 hours or more, and exhibits improved flowability and almost constant ratios among Na, Al and O along the depth direction from the surface of the zeolite particles.

Stablized synthetic zeolite and a process for the preparation thereof

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.
