Peter Wyndham Shipp - Woodstock GA

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

B01D 3916

US Classification:

210505

Abstract:

The invention provides a sheet filter medium having autogenously bonded uncrimped conjugate fibers which contain a polyolefin and another thermoplastic polymer that have different melting points. The filter medium has a density between about 0. 07 g/cm. sup. 3 and about 0. 2 g/cm. sup. 3. The invention additionally provides a three-dimensionally thermoformed filter medium that has a density between about 0. 07 g/cm. sup. 3 and about 0. 5 g/cm. sup. 3.

International Classification:

D04H 100

US Classification:

428198

Abstract:

A floor mat having costs of manufacture consistent with disposability and yet extended properties. The mat comprises a combination of a continuous filament nylon nonwoven wear surface, and absorbent inner layer comprising a mixture of polymeric microfibers and wood pulp, and a liquid impervious film backing layer. The combination is intermittently bonded such as by means of sonic energy and preferably has means for positioning and retaining the mat on a floor surface. Such means may include a holder device or tacky adhesive applied to the bottom film surface. In use the floor mat of the invention may be printed for decorative or promotional purposes and is sufficiently durable to last up to several weeks under high use conditions while yet being economical to produce. Applications for the floor mat include many consumer and industrial situations where protection from inclement weather is desired as well as in industrial clean rooms, laboratories and hospitals.

Inventors:

Clifford M. Vogt - Roswell GA
Peter W. Shipp - Woodstock GA

Assignee:

Kimberly-Clark Corporation - Neenah WI

International Classification:

B01D 3916

US Classification:

55528

Abstract:

HEPA or pre-HEPA filter media are made by forming a web of melt-blown polypropylene fibers. The melt-blown process is accomplished at a low through-put of about 1 pound per inch of die width per hour and at a high fluid flow rate of about 250 to 325 standard cubic feet per minute. The resulting web has fibers with an average diameter of about 5 microns and surface pores of less than 30 microns in size. By cold calendering the web with pressure of between 100 and 300 psi, further filter efficiency can be achieved. The resulting calendered web has surface pore sizes less than 20 microns.

International Classification:

B32B 3116

US Classification:

156 732

Abstract:

The present invention provides a self-supporting laminate filter medium having an electret lofty spunbond web and an electret microfiber web, wherein the spunbond web has a density between about 0. 01 g/cm. sup. 3 and about 0. 1 g/cm. sup. 3.

Assignee:

Kimberly-Clark Corporation - Neenah WI

International Classification:

B01D 4602

US Classification:

55279

Abstract:

A composite stove hood filter consists of a primary metal mesh filter and a nonwoven, secondary disposable filter. The secondary filter is a low basis weight (0. 2 oz. /yd. sup. 2 to 1. 0 oz. /yd. sup. 2) spun-bonded polymer sheet which is attached to the primary filter by means of elastic bands or Velcro strips. A patch of melt-blown polymer material, impregnated with air freshener, may be attached to the spun-bonded sheet of the secondary filter to freshen the air as it is filtered.

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

D04H 100

US Classification:

442352

Abstract:

There is provided in accordance with the present invention a lofty filter medium for filtering fluid-borne particles, which comprises a nonwoven fiber web of crimped fibers selected from the group consisting of spunbond fibers and staple fibers, wherein the filter medium has a density between about 0. 005 g/cm. sup. 3 and about 0. 1 g/cm. sup. 3. The lofty filter medium is highly suitable for fluid-borne particle filtration applications, such as filtration media for transmission fluids, hydraulic fluids, swimming pool water, coolant oil or cutting fluid for metalworking, metal forming and metal rolling, air-borne particle filtration and the like.

Clifford M. Vogt - Roswell GA

Assignee:

Kimberly-Clark Corporation - Neenah WI

International Classification:

B32B 702

US Classification:

428212

Abstract:

A filter medium is formed by sequentially depositing layers of melt-blown thermoplastic fibers, having the same composition but different sizes, onto a collector. The resulting laminate web has a fiber size gradient across its depth so that the large particulate can be trapped across the filter's depth without prematurely plugging the fine fiber, high efficiency layers.
