Inventor(s):	Allen; Jennifer (Crystal Lake, IL)
Assignee:	Sage Products, Inc. (Cary, IL)
Application Number:	11/208,079
Patent Claims:	1. A non-woven fabric in combination with a solution containing chlorhexidine gluconate, comprising 60% to 80% by weight of a first polyester fiber having a length of from about 1.0 inches to 3.0 inches and a denier of from about 1.2 to 2.0, and 40% to 20% by weight of a second polyester fiber having a length of from about 3.0 inches to 4.0 inches and a denier of from about 4.0 to 5.0, said fabric being formed by subjecting said fibers to carding, crosslapping and mechanical entanglement to produce a fabric with inter-engaged fibers, and said fabric absorbing and holding the solution containing chlorhexidine gluconate and releasing the chlorhexidine gluconate when wiped on skin. 2. The fabric according to claim 1, in which the length of the first polyester fiber is about 1.5 inches. 3.
