  • Non- limiting examples of processes for making fibrous structures include known wet-laid papermaking processes, which includes rush transfer and/or fabric creping and/or wet-micro contraction and/or wet pressing papermaking processes and air-laid papermaking processes.
  • Such processes typically include steps of preparing a fiber composition in the form of a suspension in a medium, either wet, more specifically aqueous medium, or dry, more specifically gaseous, i.e. with air as medium.
  • the aqueous medium used for wet-laid processes is oftentimes referred to as a fiber slurry.
  • the fibrous slurry is then used to deposit a plurality of fibers onto a forming wire or belt such that an embryonic fibrous structure is formed, after which drying and/or bonding the fibers together results in a fibrous structure. Further processing the fibrous structure may be carried out such that a finished fibrous structure is formed.
  • the finished fibrous structure is the fibrous structure that is wound on the reel at the end of papermaking, and may subsequently be converted into a finished product, e.g. a sanitary tissue product.
  • the fibrous structures of the present invention may be homogeneous or may be layered. If layered, the fibrous structures may comprise at least two and/or at least three and/or at least four and/or at least five layers.
  • the fibrous structures of the present invention may be co-formed fibrous structures.
  • Porate as used herein means a granular substance or powder.
  • Fiber and/or “Filament” as used herein means an elongate particulate having an apparent length greatly exceeding its apparent width, i.e. a length to diameter ratio of at least about 10.
  • a "fiber” is an elongate particulate as described above that exhibits a length of less than 5.08 cm (2 in.) and a “filament” is an elongate particulate as described above that exhibits a length of greater than or equal to 5.08 cm (2 in.).
  • Fibers are typically considered discontinuous in nature.
  • Non-limiting examples of fibers include wood pulp fibers and synthetic staple fibers such as polyester fibers. Filaments are typically considered continuous or substantially continuous in nature. Filaments are relatively longer than fibers.
  • Non-limiting examples of filaments include meltblown and/or spunbond filaments.
  • Non-limiting examples of materials that can be spun into filaments include hydroxyl polymers, for example natural polymers, such as starch, starch derivatives, cellulose and cellulose derivatives, hemicellulose, hemicellulose derivatives, and synthetic hydroxyl polymers including, but not limited to polyvinyl alcohol filaments and/or polyvinyl alcohol derivative filaments, and thermoplastic polymer filaments, such as polyesters, nylons, polyolefins such as polypropylene filaments, polyethylene filaments, and biodegradable or compostable thermoplastic fibers such as polylactic acid filaments, polyhydroxyalkanoate filaments and polycaprolactone filaments.
  • the filaments may be monocomponent or multicomponent, such as bicomponent filaments.
  • the hardwood and softwood fibers can be blended, or alternatively, can be deposited in layers to provide a stratified web.
  • U.S. Pat. No. 4,300,981 and U.S. Pat. No. 3,994,771 are incorporated herein by reference for the purpose of disclosing layering of hardwood and softwood fibers.
  • fibers derived from recycled paper which may contain any or all of the above categories as well as other non-fibrous materials such as fillers and adhesives used to facilitate the original papermaking.
  • suitable hardwood pulp fibers include eucalyptus and acacia.
  • suitable softwood pulp fibers include Southern Softwood Kraft (SSK) and Northern Softwood Kraft (NSK).
  • “Repeating design element” as used herein with respect to a surface pattern means a design element that repeats two or more, and/or a plurality of times within the surface pattern. In one example, two or more and/or greater than 15% and/or greater than 25% and/or greater than 50% and/or greater than 75% and/or 100% of the repeating design elements are connected to at least one other adjacent design element within the surface pattern. In one example, the plurality of repeating design elements covers greater than 5% and/or greater than 10% and/or greater than 20% and/or greater than 30% and/or greater than 40% and/or greater than 50% and/or greater than 60% and/or greater than 70% and/or to about 100% and/or to about 90% and/or to about 80% of the surface area of the sanitary tissue product.
  • the surface pattern 20b comprises a plurality of repeating design elements 10b as shown in Fig. 7.
  • two or more repeating designs 10b are connected to each other through their respective opposing open termini 16 as represented by the letter "O", which forms a channel 22b between the connected repeating design elements 10b.
  • This channel 22b is sandwiched between two opposing closed termini 18 as represented by the letter "C” of two adjacent repeating design elements 10b.
  • This arrangement of the connected opposing open termini 16 of repeating design elements 10b being sandwiched between opposing closed termini 18 of repeating design elements 10b gives the appearance of a woven surface pattern and/or woven cloth and/or fabric.

A eucalyptus fiber slurry is pumped through the top headbox chamber, a eucalyptus fiber slurry is pumped through the bottom headbox chamber (i.e.
