    摘要： The present invention provides a method of treating a porous substrate that includes contacting a surfactant or a mixture of surfactants to a surface of the porous substrate such that opposite surface of the porous substrate contacts a lesser amount of the surfactant or mixture of surfactants than the first surface contacts. The present invention also provides a porous, treated substrate that includes a first surface that includes a first amount of a surfactant or mixture of surfactants and a second surface that includes a lesser amount of the surfactant or the mixture of surfactants.

    摘要： Multipurpose cleaning articles are provided comprising a porous cleaning sheet containing an aqueous cleaning composition comprising (a) water as the major component; (b) 5% to 45% by weight water-immiscible solvent; (c) less than about 1.8% by weight emulsifier; and wherein the aqueous cleaning composition has a vertical wicking rate of about 1 cm/minute or more. The porous cleaning sheet can comprise any one of numerous materials, including hydrophobic materials, such as nonwoven webs, textile fabrics, foams and so forth. The cleaning articles are capable of removing water insoluble materials from various surfaces and including cleaning the skin and hands as well as hard surfaces.

    摘要： A coated porous substrate composed of a hydrophobic polymer which is substantially uniformly coated with a hydrophilic polymeric material. The substrate may be a sheet-like material, examples of which are foams, fibers, and fibrous webs. The fibrous webs desirably will be nonwoven webs. The coating on the substrate is durable to an aqueous medium at a temperature in a range of from about 10.degree. C. to about 50.degree. C. and does not significantly suppress the surface tension of an aqueous medium with which the coated substrate may come in contact. The hydrophobic polymer may be a polyolefin, such as polyethylene or polypropylene. The hydrophilic polymeric material with which the polymer fibers are coated may be a polysaccharide or a modified polysaccharide. Also provided is a method of preparing a coated porous substrate which involves providing a porous substrate composed of a hydrophobic polymer. At least a portion of the substrate then is exposed to a field of reactive species. At least a portion of the porous substrate, including the portion exposed to the reactive species, is treated with a mixture which includes water and a hydrophilic polymeric material under conditions sufficient to substantially uniformly coat the porous substrate with the hydrophilic polymeric material.
