MULTIPLE APPLICATION MELTBLOWN NONWOVEN WET WIPE AND METHOD

摘要

A wet wipe which includes a pattern bonded polypropylene nonwoven web adapted to provide a sustained controlled release to a surface of an aqueous alcoholic composition contained within the nonwoven web. The nonwoven web has a basis weight of from about 17 to about 100 grams per square meter and includes polypropylene meltblown fibers having diameters in a range of from about 0.01 toabout 50 micrometers. The aqueous alcoholic composition contained within the polypropylene nonwoven web is present in a range of from about 300 to about 600 weight percent based on a dry weight of the nonwoven web of 34 grams per square meter. The wet wipe provides a first release of the aqueous alcoholic composition in a range of from about 40 to about 70 weight percent, a second release in a range of from about 10 to about 25 weight percent and a third release in a range of from about 5 to about 18 weight percent, of the composition originally present in thenonwoven web. The total amount of the aqueous alcoholic composition remaining inthe nonwoven web after three releases is no more than about 25 weight percent based on the amount of the composition originally present. Also provided is a method of applying a sustained controlled release of an aqueous alcoholic composition to a surface.
