Specific zeolite particles retaining therein a metal ion having a bactericidal activity are packed and retained in a mixed fiber assembly composed of low-melting thermoplastic synthetic fibers and ordinary fibers. The zeolite particles are retained by welding of the low-temperature thermoplastic syn ...
A polymer article containing zeolite particles on which metal ion having a bactericidal property, e.g. Ag, Cu or Zn, is provided by an ion exchange reaction shows an excellent bactericidal effect and durability of the effect, but no deterioration of physical properties of the polymer.
Zeolite particles retaining at least one metal ion having bacteriostatic properties on their ion-exchangeable sites in an amount up to 41% of the zeolite's ion exchange capacity are described.
Zeolite particles retaining silver ions having bacteriostatic properties on their ion-exchangeable sites in an amount up to 41% of the zeolite's exchange capacity are described.
