Abstract
Through-air dried (“TAD”) fibrous structures, especially TAD fibrous structures incorporated into sanitary tissue products, that comprise a short fiber furnish having a length of from about 0.4 mm to about 1.2 mm and a coarseness of from about 3.0 mg/100 m to about 7.5 mg/100 m, and processes for making such TAD fibrous structures are provided.
Claims20
A through-air dried fibrous structure comprising:
- a. a short fiber furnish comprising a short fiber having a length of from about 0.4 mm and about 1.2 mm and a coarseness of from about 3.0 mg/100 m to about 7.5 mg/100 m, and
- b. a physical property ingredient selected from the group consisting of permanent wet strength resins, chemical softeners and mixtures thereof.
A process for making a through-air dried fibrous structure comprising the steps of:
- a. preparing a fibrous furnish comprising a short fiber furnish comprising a short fiber having a length of from about 0.4 mm to about 1.2 mm and a coarseness of from about 3.0 mg/100 m to about 7.5 mg/100 m, by mixing the short fiber with water to form the short fiber furnish;
- b. depositing the fibrous furnish on a foraminous forming surface to form an embryonic fibrous web;
- c. adding a permanent wet strength resin to the fibrous furnish and/or the embryonic fibrous web;
- and
- d. through-air drying said embryonic fibrous web such that the through-air dried fibrous structure is formed.
A process for making a through-air dried, chemical softener-containing fibrous structure comprising the steps of:
- a. preparing a fibrous furnish comprising a short fiber furnish comprising a short fiber having a length of from about 0.4 mm to about 1.2 mm and a coarseness of from about 3.0 mg/100 m to about 7.5 mg/100 m, by mixing the short fiber with water to form the short fiber furnish;
- b. depositing the fibrous furnish on a foraminous forming surface to form an embryonic fibrous web;
- c. through-air drying said embryonic fibrous web such that through-air dried fibrous structure is formed;
- and
- d. applying a chemical softener to the fibrous furnish and/or embryonic fibrous web and/or through-air dried fibrous structure such that the through-air dried, chemical softener-containing fibrous structure is formed.
