A method for hydrophilizing a hydrophobic surface of a substrate includes the steps of (a) defining a temperature range of: (i) greater than or equal to an anticipated lower use temperature (LUT), or (ii) less than or equal to an anticipated upper use temperature (UUT), or (iii) from a LUT to an UUT, wherein LUT≦UUT, within which the substrate is intended to be used in the presence of water, and (b) depositing at least one polymer on at least a portion of the surface, said polymer being soluble in water to the extent that an aqueous solution of such polymer exhibits: (i) a lower critical solution temperature (LCST), wherein LCST<LUT, or (ii) an upper critical solution temperature (UCST), wherein UUT<UCST, or (iii) a LCST and a UCST, wherein UCST<LCST and: (1) LCST<LUT, or (2) UUT<UCST.
A method for hydrophilizing a hydrophobic surface of a substrate, comprising:
A hydrophilized fabric intended for use in the presence of water within a temperature range of greater than or equal to an anticipated lower use temperature (LUT), or less than or equal to an anticipated upper use temperature (UUT), or from a LUT to an UUT, wherein LUT≦UUT, comprising:
A disposable absorbent article intended for use in the presence of water within a temperature range of greater than or equal to an anticipated lower use temperature (LUT), or less than or equal to an anticipated upper use temperature (UUT), or from a LUT to an UUT, wherein LUT≦UUT, comprising a hydrophilized fabric, said fabric comprising:
A disposable absorbent article selected from diapers, adult incontinence products, wipes, and feminine hygiene products, comprising at least one porous hydrophilized fabric substrate, said porous hydrophilized fabric substrate comprising fibers having hydrophobic surfaces and at least one polymer deposited on at least a portion of the fiber surfaces, said polymer being soluble in water to the extent that an aqueous solution of such polymer exhibits a lower critical solution temperature of less than 20° C.
