Benefits of technology

[0007]The present invention relates to a multiply fibrous structure product comprising: two or more plies of fibrous structure wherein the fibrous structure has a High Load Caliper of from 17 mils to about 45 mils. The present invention further relates to a multiply fibrous stru

Problems solved by technology

Usually, however, the improvement of one attribute, may compromise the quality of another attribute.
For example, increasing bulk of a fibrous structure may increase the absorbency while also increasing the stiffness of the product thereby decreasing the softness.
Therefore, providing a product with improved bulk and therefore an improved impression of strength and durability without sacrificing the softness and flexibility of the product is difficult.

example 1

[0079]One fibrous structure useful in achieving the fibrous structure paper products of the present invention is a through-air-dried (TAD), differential density structure formed by the following process. (Examples of TAD structures are generally described in U.S. Pat. No. 4,528,239.)

[0080]A Fourdrinier, through-air-dried papermaking machine is used. A slurry of papermaking fibers is pumped to the headbox at a consistency of about 0.15%. The slurry consists of about 70% Northern Softwood Kraft fibers, about 30% unrefined Eucalyptus fibers, a cationic polyamine-epichlorohydrin wet burst strength resin at a concentration of about 25 lbs per ton of dry fiber, and carboxymethyl cellulose at a concentration of about 5 lbs per ton of dry fiber, as well as DTDMAMS at a concentration of about 6 lbs per ton of dry fiber.

[0081]Dewatering occurs through the Fourdrinier wire and is assisted by vacuum boxes. The embryonic wet web is transferred from the Fourdrinier wire at a fiber consistency of ...

[0086]One fibrous structure useful in achieving the fibrous structure paper products of the present invention is a through-air-dried (TAD), differential density structure formed by the following process. (Examples of TAD structures are generally described in U.S. Pat. No. 4,528,239.)

[0087]A Fourdrinier, through-air-dried papermaking machine is used. A slurry of lo papermaking fibers is pumped to the headbox at a consistency of about 0.15%. The slurry consists of about 70% Northern Softwood Kraft fibers, about 20% unrefined Eucalyptus fibers, and about 10% of bicomponent fibers of copolymers of polyester (polyethylene terephthalate) / polyester (polyethylene terephthalate) such as “CoPET / PET” fibers, which are commercially available from Fiber Innovation Technology, Inc., Johnson City, Tenn. The slurry further comprises a cationic polyamine-epichlorohydrin wet burst strength resin at a concentration of about 25 lbs per ton of dry fiber, and carboxymethyl cellulose at a concentration of...

Abstract

A fibrous structure product having two or more plies of fibrous structure having a High Load Caliper from 17 mils to about 45 mils. In addition a multiply fibrous structure product having two or more plies, a High Load Caliper from about 17 mils to about 45 mils; a basis weight from about 26 lbs / 3000 ft2 to about 50 lbs / 3000 ft2; and a Flex Modulus from about 0.1 to about 0.8.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 60 / 797,245 filed on May 3, 2006.FIELD OF THE INVENTION[0002]The present invention relates to fibrous structure products, more specifically multi-ply fibrous structure products having multiple enhanced attributes and methods of making the same.BACKGROUND OF THE INVENTION[0003]Cellulosic fibrous structures are a staple of everyday life. Cellulosic fibrous structures are used as consumer products for paper towels, toilet tissue, facial tissue, napkins, and the like. The large demand for such paper products has created a demand for improved versions of the products and the methods of their manufacture.[0004]Consumers prefer cellulosic fibrous structure products having multiple attributes. These attributes include softness, absorbency, strength, flexibility, and bulk. Consumers may especially prefer fibrous structure products having higher bulk, including those having rela...
