Abstract
Antimicrobial nonwoven webs are provided which have odor control properties in addition to antibacterial properties, and which can be used in personal care absorbent articles. The nonwoven webs are treated with a stable halogenated polystyrene hydantoin which does not release halogen during storage or use of the absorbent article. The halogen atoms are attached to the amide nitrogen atoms in the polystyrene hydantoin, and are not attached to the imide nitrogen atoms.
Claims37
An antimicrobial nonwoven web having odor control properties, comprising:
- a plurality of nonwoven fibers;
- and
- a halogenated polystyrene hydantoin including a plurality of repeating units and halogen atoms chemically linked to the repeating units;
- each of the repeating units including an amide nitrogen atom and an imide nitrogen atom;
- wherein at least about 90% of the halogen atoms are chemically linked to the amide nitrogen atoms.
An antimicrobial absorbent nonwoven web having odor control properties, comprising:
- a plurality of absorbent nonwoven fibers;
- and
- about 0.1-10% by weight of a chlorinated polystyrene hydantoin including a plurality of repeating units and chlorine atoms chemically linked to the repeating units;
- each of the repeating units including an amide nitrogen atom and an imide nitrogen atom;
- wherein at least about 90% of the chlorine atoms are chemically linked to the amide nitrogen atoms.
An antimicrobial nonabsorbent nonwoven web having odor control properties, comprising:
- a plurality of non-retentive nonwoven fibers;
- and
- about 0.1-10% by weight of a chlorinated polystyrene hydantoin including a plurality of repeating units and chlorine atoms chemically linked to the repeating units;
- each of the repeating units including an amide nitrogen atom and an imide nitrogen atom;
- wherein at least about 90% of the chlorine atoms are chemically linked to the amide nitrogen atoms.
