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.

The fabric according to claim 1, in which the denier of the second polyester fiber is about 4.75. 6. The fabric according to claim 1 which has a weight of from about 3.8 to about 5.8 ounces per square yard. 7. The fabric according to claim 6 which has a weight of 4.8 ounces per square yard. 8. The fabric according to claim 1 in which said mechanical entanglement is needle punching. 9. The fabric according to claim 1 having a thickness from about 0.055 inches to about 0.125 inches. 10. The fabric according to claim 9 in which the thickness is 0.090 inches. 11. 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 not chemically or mechanically binding with chlorhexidine gluconate of the solution containing chlorhexidine gluconate. 12.
