Application 10/065,436
by specified fluid absorption properties. The product absorption property is
recited as a volume percent moisture absorption and/or is conveyed in terms
of other allegedly related physical properties, such as length of the fibers
and/or the number or functional character of openings in the filament.
Claims 2, 4, 8, 15, 16, 28, 29, 30, 37, and 72 are illustrative and reproduced
below:
2. A hollow polyester filament consisting essentially of
polyethylene terephthalate having sufficient openings therein for said hollow
filament to substantially fill with a liquid selected from the group consisting
of water, water-based solutions, and water-based suspensions.
4. A staple fiber cut from the hollow filament of Claim 2.
8. A nonwoven fabric formed from a plurality of staple fibers
according to Claim 4.
15. A hollow staple fiber consisting essentially of polyethylene
terephthalate and having sufficient openings therein for said staple fiber to
substantially fill with water.
16. A polyester filament having a moisture absorption capability of
between about 10 and 30 percent by volume.
28. A staple fiber consisting essentially of polyethylene terephthalate
and having a moisture absorption capability of between about 10 and 30
percent by volume.
29. A hollow filament having an asymmetric cross section and having
sufficient openings therein for said hollow filament to substantially fill with
liquid.
30. A hollow polyester filament having an asymmetric cross section
and having sufficient openings therein for said hollow filament to
