Methods of making soft absorbent sheets and absorbent sheets made by such methods
A method of making a fabric-creped absorbent cellulosic sheet. The method includes compactively dewatering a papermaking furnish to form a web, creping the web under pressure in a creping nip between a transfer surface and a structuring fabric, the structuring fabric including knuckles formed on warp yarns of the structuring fabric, with the knuckles being positioned along lines that are angled relative to the machine direction of the fabric. The angle of lines relative to the machine direction is between about 10° and about 30°. The method also includes drying the web to form the absorbent cellulosic sheet.
A METHOD FOR PRODUCING A FILM COMPRISING NANOCELLULOSE, AND A FILM COMPRISING NANOCELLULOSE
The present invention relates to a method for producing a film comprising nanocellulose, which method comprises: providing a suspension comprising 50-100 weight-% of nanocellulose based on total dry weight; forming a fibrous web of said suspension on a non-porous support; providing a press fabric comprising a web-side first surface and an opposite second surface, wherein said press fabric comprises a woven first fabric layer arranged in the press fabric as a layer providing said web-side first surface such that said press fabric has a woven surface structure at said web-side first surface; applying said web-side surface of said press fabric into direct contact with said web; wet-pressing said web by conducting said web, arranged between said press fabric and said non-porous support, through a pressing equipment, and drying the dewatered web so as to form said film. The invention further relates to a film produced from said method.
Woven papermaking fabric including stabilized weave providing textured contacting surface
The present invention relates to papermaking fabrics useful in the manufacture of paper products, such as tissue paper. Particularly this invention relates to a woven papermaking fabric that includes a stabilized weave providing a textured contacting surface. The woven papermaking fabric includes a plurality of warp and shute filaments woven together to provide at least one protuberance on the web contacting side of the fabric that extends longitudinally over at least five shute filaments. The at least one protuberance is stabilized by including an offset shute float weave pattern configured such that a majority of the shute filaments forming the at least one protuberance are woven in an anti-nesting configuration.
WOVEN PAPERMAKING FABRIC HAVING CONVERGING, DIVERGING OR MERGING TOPOGRAPHY
Provided are woven papermaking fabrics having a web contacting surface having protuberances formed from woven warp and shute filaments. The protuberances, which may be oriented in the machine direction (MD) converge, merge, or diverge and may be arranged to form a pattern. In certain instances, the protuberance may comprise a first MD oriented protuberance having an element angle from about 0.5 to about 15 degrees, a second MD oriented protuberance having an element angle from about −0.5 to about −15 degrees wherein the first and second protuberances converge at a convergence area to form a third MD oriented protuberance having an element angle from about −15 to about 15 degrees.
TISSUE PRODUCTS HAVING EMBOSS ELEMENTS WITH REDUCED BUNCHING AND METHODS FOR PRODUCING THE SAME
Products having reducing tissue wrinkling, puckering, and bunching and improved emboss definition, emboss visibility, and perceived softness are described. The methods comprise embossing the tissue sheet with a emboss elements having segments aligned in the machine direction and including an abatement component, such as a tapered width or a multi dual-apex, that can absorb machine direction stretch during the production of the product.
Mask and Papermaking Belt Made Therefrom
A fibrous structure may have a lower side and an upper side, and may comprise three-dimensional, out-of-plane features formed by knuckles on a papermaking belt, the features may exhibit at least two Z-direction spatially separated surfaces defined in order spatially with respect to the lower side, wherein each successive surface progressing in a Z-direction away from the lower side may have a projected area less than the projected area of the surface adjacent and closer to the lower side, and each projected area may be bounded completely by the area of the projected area of the surface adjacent and closer to the lower side.
Unitary Deflection Member for Making Fibrous Structures Having Increased Surface Area and Process for Making Same
A unitary deflection member. The unitary deflection member can have a fluid pervious reinforcing member and a patterned framework. The patterned framework can have a plurality of regularly spaced protuberances extending from the reinforcing member. At least two of said protuberances can be similar in size and shape, and can have linear segments having different cross-sectional areas along the z-direction.
PAPERMAKING MACHINE WITH PRESS SECTION
A machine or apparatus for producing structured tissue or towel using a press section.
Creped fibrous structures
Creped fibrous structures having pillows and knuckles, wherein the creped fibrous structures may exhibit improved knuckle properties, such as Knuckle Roughness Ra, Knuckle Roughness Rq, and Knuckle Creping Frequency and methods for making same are provided, and/or may comprise elongate knuckles comprising discrete pillows and/or elongate pillows between first and second elongate knuckles.
METHOD FOR PRODUCING A FOAM WEB
Method for producing a sterilized foam web, wherein the method comprising the steps of preparing a wet foam (1),feeding the wet foam (1) to a head box (2, 11),distributing the wet foam by the head box (2, 11),treating the wet foam (1) with electron beam radiation (3a, 3b, 3c) to immobilize and sterilize the wet foam (1),receiving the electron beam treated foam on a moving wire (4) to form a foam web (6, 13), pressing and the foam web (6, 13),and drying the foam web (6, 13).
