Abstract: There is disclosed a novel cellulosic web and a method for its manufacture. The web is fabricated of fibrous material and is characterized by one of its surfaces being nubby. Such web is formed by the deposition of fibers from an aqueous slurry onto the surface of a multiplex forming fabric defining pockets in one surface thereof, under conditions of flow and rate of water removal that establish high shear fluid flow and result in the orientation of fibers and/or fiber segments at an angle with respect to the plane of the forming fabric. The resultant web has a high apparent bulk and good absorbency and strength properties.

Abstract: A food packaging material suitable for a variety of food service applications, including fast food restaurants is provided. The packaging is preferably formed from a flexible laminate sheet that includes at least one moisture impervious layer and has been formed into a receptacle having a shape suitable for enclosing and sealing fast food sandwiches and the like. Attached to the sheet is a length of rip cord having at least one free end that can be grasped and pulled by the consumer to tear the laminate sheet, thereby opening the sealed food-containing receptacle. The rip cord can be attached so that it causes one portion of the receptacle to be partially or completely separated from a remaining receptacle portion. The separated portion of the receptacle can be folded out of the way or discarded, and the remaining receptacle portion used to enclose the food product to form a convenient pouch for protecting the consumer's hands while holding the food product.

Abstract: A wetlaid paper-like nonwoven structure having a permanent crepe which does not wash out. The paper-like structure contains a synthetic bicomponent fiber in an amount of less than 20% by weight and as such possesses both wet and dry strength and improved absorbent properties.

Abstract: A method is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, embossed webs separated from one another and longitudinally displaced relative to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. Prior to recombining the webs, the embossments on one of said web is smoothed out increasing the absorbency and softness if the web.

Abstract: A converted product which is particularly high both in bulk and in perceived softness is produced by pre-embossing the plies individually, joining the plies and calendering and again embossing. In another example, the pre-emboss step is omitted.

A method of forming a delaminated stratified web of paper towel material includes supplying a first furnish directly to a wire and supplying a second furnish of a bulky anfractuous fiber blend directly onto the first furnish disposed on the wire. Drying the first and second furnishes forms a web of paper towel material having a predetermined dryness. The web of paper towel material is thereafter creped off of the drying device and embossed to a predetermined emboss depth. The web of paper towel material has an enhanced rate of absorption and water holding capacity.
