Abstract: Webs are formed by mixing chemically modified cellulose fibers in a carrier and dewatering to form a mixture of gel-like consistency having a minimum of external water wherein the fibers have not lost their individual structures. This mixture is sprayed or injected into a gas stream of volume and velocity such that the individual fibers are separated. These fibers are collected into highly-absorbent webs having varying structures. Due to the rapid separation of fibers and subsequent drying, reduced interfiber hydrogen bonding takes place resulting in good tactile properties such as softness and drape. By controlling the direction and velocity of the fibers, webs can be produced having structures ranging from very dense mats to loose, fluffy batt-like products. The webs of the invention possess high absorbency, good wicking, and strength sufficient for handling. They may be used as components for wipers, surgical sponges, and personal care products such as sanitary napkins, tampons, and disposable diapers.

Abstract: Absorbent paper sheets in multi-ply web form in which the outer webs of the sheet are creped and consist of a series of ribs and grooves. The webs have their ribs secured together by adhesive dispersed in a pattern consisting of individual adhesive zones. The adhesive zones are obtained by providing in embossing apparatus cooperable rolls each having alternating ribs and grooves, the ribs of one roll being provided with protuberances and the other with recesses. The protuberances cover a relatively small area of the total rib area and carry a web on the protuberances through an adhesive applicator so that a relatively small area of the web receives adhesive for attachment to a second web.
