Claims (5)

A non-tobacco product comprising, a non-tobacco material having fibrous structures and a total oven volatiles content of about 20% by weight or greater; and two layers of melt-blown polyurethane structural fibers positioned on opposite sides of the non-tobacco material such that one layer of the melt-blown polyurethane structural fibers is positioned on each of the opposite sides, the melt-blown polyurethane structural fibers having a diameter of 100 microns or less.
The non-tobacco product of claim 1, wherein each layer of melt-blown polyurethane structural fibers comprises a basis weight of about 30 grams per square meter (gsm).
The non-tobacco product of claim 1, wherein the non-tobacco material comprises a herbal composition.
The non-tobacco product of claim 3, wherein the herbal composition comprises a culinary herb, thyme, lavender, rosemary, coriander, dill, mint, peppermint, a medicinal herbs, dahlia, cinchona, foxglove, meadowsweet, Echinacea, elderberry, willow bark, or combinations thereof.

Description

This disclosure generally relates to a smokeless tobacco product including smokeless tobacco entangled with structural fibers to form a tobacco-entangled fabric. Methods of making and using the tobacco-entangled fabric are also described.

Smokeless tobacco is tobacco that is placed in the mouth and not combusted. There are various types of smokeless tobacco including: chewing tobacco, moist smokeless tobacco, snus, and dry snuff. Chewing tobacco is coarsely divided tobacco leaf that is typically packaged in a large pouch-like package and used in a plug or twist. Moist smokeless tobacco is a moist, more finely divided tobacco that is provided in loose form or in pouch form and is typically packaged in round cans and used as a pinch or in a pouch placed between an adult tobacco consumer's cheek and gum. Snus is a heat treated smokeless tobacco. Dry snuff is finely ground tobacco that is placed in the mouth or used nasally.

A smokeless tobacco product is described that includes a smokeless tobacco material and structural fibers of a material having a composition different from the smokeless tobacco. The structural fibers form a network in which the smokeless tobacco is entangled to form a tobacco-entangled fabric. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers. A method of preparing the smokeless tobacco product is also described.
