Abstract
Fibrous structures, especially fibrous structures incorporated into facial tissue, toilet tissue and paper towel and napkin products, that comprise a 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, wherein the fibrous structures exhibit a lint value of greater than about 3.5 to about 15, and processes for making such fibrous structures are provided.
Claims22
A fibrous structure comprising 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, wherein the said fibrous structure has a lint value of greater than about 3.5 to about 15.
A process for making a 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;
- and
- c. drying said embryonic fibrous web such that that the dried fibrous structure is formed.
A process for making a soft fibrous structure comprising the steps of:
- a. identifying a first fiber that exhibits a softness value greater than a second fiber, wherein a fibrous structure comprising the first fiber has a lint value about equal to or less than a fibrous structure comprising the second fiber;
- and
- b. incorporating the first fiber into a fibrous structure to form the soft fibrous structure.
A process for making a soft fibrous structure comprising the steps of:
- a. identifying a first fiber, that when incorporated into a first fibrous structure at a level of at least 10% by weight of the total fibers present in the first fibrous structure, exhibits a first softness value and a first lint value;
- b. identifying a second fiber, that when incorporated into a second fibrous structure at the same level as the first fiber is incorporated into the first fibrous structure, exhibits a second softness value which is less than the first softness value and a second lint value which is greater than the first lint value;
- and
- c. incorporating the first fiber into a fibrous structure to form the soft fibrous structure;
- and
- d. optionally, incorporating the soft fibrous structure into a paper product.
