Abstract A disposable liquid absorbent pad is illustrated wherein a wicking sheet of creped paper is utilized for supporting a cast film of acrylic polymer capable of forming a gel upon application of liquid thereto, there being a direct mechanical connection between the ridged surfaces of the creped paper and the film, and preferably voids between the ridges of the wicking sheet. The film is laminated to the creped wicking sheet by moistening one surface of the film as by a spray mist of liquid and then applying the resulting gel or tacky side to the ridges of the creped sheet. The product thus formed is suitable for use adjacent the human body and has particular application for use as diapers, underpads and bandages or wherever the absorption of liquids quickly and in relatively large amounts is desirable.
The method of making a disposable liquid absorbent pad for use as a diaper sanitary napkin and the like comprising the steps of: forming a film of polymeric material capable of forming a gel upon application of liquid thereto; providing a crinkled absorbent sheet having apex portions for receiving said film thereacross; and producing a controlled amount of gel on said film forming a limited bond with said sheet at the apex portions facilitating wicking of liquid applied to the pad thus formed through voids between apex portions of said crinkled absorbent sheet.
