Filed:

Sep 24, 1997

Appl. No.:

8/936156

Inventors:

William Francis Cartwright - Roswell GA
Carol Ann Blaney - Roswell GA

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

B32B 516

US Classification:

442417

Abstract:

Disclosed is a fabric which includes a microbial adsorbent and which is capable of providing a microbial barrier while still being able to allow passage of water vapor. The fabric is formed from a plurality of fibers which define at least one microporous passageway which allows communication, through the fabric, between its respective first and second surfaces. In particular, a portion of the microporous passageway is defined by the microbial adsorbent so that microbes attempting to pass through the fabric via such a passageway must pass in close proximity to the microbial adsorbent. This arrangement allows the microbial adsorbent to interdict the microbe by adsorbing it. Passage of the microbe through the fabric is thereby prohibited. Laminates of the fabric with other materials are also disclosed.

US Classification:

131365

Abstract:

There is disclosed a method of coloring cigarette paper. Cigarette paper is made by forming a furnish, adding at least one colorant to the furnish, forming a sheet of paper from the thus treated furnish, and adding at least one colorant to the paper to produce a variety of tans/browns and red-brown cigarette wrapper.

US Classification:

131370

Abstract:

An improved method of making reconstituted tobacco using a dry-forming process. Fiberized tobacco stems and scrap are combined with tobacco material of a fine particle size. The resulting tobacco mixture is conveyed in an airstream and deposited on a moving foraminous surface. An adhesive is incorporated into or applied to the web bonding the tobacco particles into a coherent sheet, and the sheet is dried if necessary. The dried sheet may be divided into leaflets or shredded for further processing as reconstituted tobacco. In preferred embodiments, cellulose fibers are mixed with the tobacco particles prior to web formation to impart increased sheet strength. In a further embodiment tobacco fines are mixed with the adhesive and applied to the web in the adhesive composition. Results obtained by means of the present invention include cost savings particularly in terms of reduced capital costs. Because the tobacco is used substantially in its natural state, the aroma and other desirable tobacco attributes are retained.

US Classification:

131332

Abstract:

Nonwoven web comprising thermoplastic meltblown fibers or filaments predominantly present as agglomerates or multiple fused fiber areas. Such agglomerates in the web act as columns and impart a desired degree of strength and resistance to compaction. In contrast to prior art webs where such agglomerates have been considered undesirable, the webs of the present invention find particular utility when formed into cylinders as filter plugs for smoking articles. In smoking articles of the invention, the filter plugs have a desired pressure drop while demonstrating an unexpected degree of firmness, all at an economically attractive cost. Preferred embodiments include those where the machine direction strength to cross machine direction grab tensile ratios in the range of from about 1:1 to 4:1 and the fibers or filaments are made from polypropylene. Other embodiments include webs and filter plugs containing additives distributed throughout the web.

US Classification:

131365

Abstract:

A flavor release material and method for producing the same where the material contains a calculated amount of active surface agent and flavorant adsorbed onto the active surface agent. The flavor release material is capable of controllably releasing flavor and aroma when exposed to a predetermined elevated temperature.

International Classification:

B32B 326

US Classification:

4283155

Abstract:

A self-regulating breathable microporous film layer transmits water vapor at normal use conditions, and reduces or eliminates the vapor transmission when the vapor in the environment becomes excessive. The film layer includes a voided polymer matrix and a plurality of fine water-swellable filler particles disposed within the voids. When there is an excess of vapor, the filler particles swell to block or partially block transmission of vapor through the voids and the film layer.

Abstract:

There is disclosed a method of producing a non-burning wrapper for use with smoking products. A non-burning wrapper is formed by treating a base paper with a solution consisting essentially of water, calcium chloride and a reactive size for paper; drying the thus treated paper; coating one side of the thus treated base paper with a solution consisting essentially of water, calcium carbonate, potassium silicate and sodium carboxymethycellulose; and drying the thus treated and coated paper to form a non-burning wrapper for use with smoking products.
