to one or more internal lengthwise open channels. Each open
channel has an opening and at least one groove which has a
defined mouth. The mouth has a width such that the average
transverse
cross-sectional area of the groove is greater than or equal to
B(width) /8 and a durable hydrophilic surface modifier is2
associated with the channel (Brief, page 2).
Claim 1 is illustrative of the subject matter on appeal
and is reproduced below:
1. A thermoplastic fiber demonstrating moisture wicking
properties comprising:
a) a fiber surface defining an outer boundary and
one or more internal lengthwise open channels each having an
opening and at least one groove having a longest dimension, a
deepest point and a mouth, said mouth defined by moving a line
which is perpendicular to said longest dimension from said
deepest point along said longest dimension until a largest
convex set is defined, said mouth having a width wherein the
average transverse cross-sectional area of the groove is
greater than or equal to (B(width) )/8; and2
b) a durable hydrophilic surface modifier
associated with said channel.
