Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 157 words
A particle-packed fiber article having an antibacterial property comprising zeolitic particles retaining therein at least one metal ion having a bactericidal property and having a specific surface area of at least 150 m 2 /g and a SiO 2 /Al 2 O 3 mol ratio of at most 14 and a mixed fiber assembly composed of a natural fiber staple or synthetic fiber staple and a fiber staple containing low-melting thermoplastic synthetic fibers having a melting point at least 30°C lower than the melting point or the decomposition point of the aforesaid natural fiber staple or synthetic fiber staple, at least a part of the intersection points of the staple of said mixed fiber assembly being stuck to each other by the fusion of the low-melting thermoplastic synthetic fibers, whereby said zeolitic particles are incorporated and retained in the fiber assembly in the state of allowing the contact of the foregoing zeolitic particles with an external fluid.
Claim 2
Dependent Claim 157 words
A particle-packed fiber article having an antibacterial property comprising zeolitic particles retaining therein at least one metal ion having a bactericidal property and having a specific surface area of at least 150 m 2 /g and a SiO 2 /Al 2 O 3 mol ratio of at most 14 and a mixed fiber assembly composed of a natural fiber staple or synthetic fiber staple and a fiber staple containing low-melting thermoplastic synthetic fibers having a melting point at least 30°C lower than the melting point or the decomposition point of the aforesaid natural fiber staple or synthetic fiber staple, at least a part of the intersection points of the staple of said mixed fiber assembly being stuck to each other by the fusion of the low-melting thermoplastic synthetic fibers, whereby said zeolitic particles are incorporated and retained in the fiber assembly in the state of allowing the contact of the foregoing zeolitic particles with an external fluid.
Claim 3
Dependent Claim 29 words
The particle-packed fiber article having an anti-bacterial property as claimed in claim 1 wherein the zeolitic particles are composed of A-type zeolite, X-type zeolite, mordenite, or a mixture thereof.
Claim 4
Dependent Claim 45 words
The particle-packed fiber article having an antibacterial property as claimed in claim 1 or 2 wherein the zeolitic solid particles retain at least one metal ion having a bactericidal activity selected from the group consisting of silver, copper, and zinc at the ion-exchangeable sites thereof.
Claim 5
Dependent Claim 47 words
The particle-packed fiber article having an antibacterial property as claimed in one of claims 1 to 3 wherein the amount of the zeolite solid particles packed in the mixed fiber assembly is in a range of 0.1 to 60% by weight (as anhydrous zeolite) to the fiber.
