Abstract
Abstract A wipe material capable of retaining opposed wet and dry facings characterized by (A) a wet facing comprising one or more fiber- or fiber-like-web(s) having hydrophilic/hydrophobic component blends of indicated wt. % ranges and denier and (B) a dry facing comprising one or more fiber- or fiber-like-webs containing one or more hydrophobic components of mixed denier not exceeding a given denier; and a method for obtaining the same.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
153 words
A wipe material comprising in combination, (A) a wet facing consisting essentially of one or more externally positioned and internally positioned fiber-and/or fibrillated film-web of blended hydrophilic/hydrophobic components totaling about 50-90/50-10 wt. % respectively, the hydrophilic component of each web of said wet facing having a denier within a range of about 0.5-2.0 dpf, and the hydrophobic component of each web of said wet facing having a denier not exceeding about 6 dpf; wherein (a) said externally-positioned web of said wet facing contains not less than about 60 wt. % of said hydrophilic component, and fiber- and/or fibrillated film-components thereof are of about the same denier; and (b) said internally-positioned web(s) of said wet facing contain fiber- and/or fibrillated film-components of mixed denier; secured to (B) a dry facing consisting essentially of one or more webs comprising one or more hydrophobic fiber- and/or fibrillated film-components of mixed denier not exceeding about 6 dpf.
