Appl. No.:

09/732258

Inventors:

Charles Edward Edmundson - Roswell GA
Bryon Paul Day - Canton GA

Assignee:

Kimberly-Clark Worldwide, Inc. - Neenah WI

International Classification:

B01D 5302

US Classification:

95 52, 96 4, 96 10, 21050027, 21050035, 21050036, 21050038, 21050042, 521 54, 523218, 442370, 442375

Abstract:

A breathable, stretch-thinned barrier film having improved strength, processability and/or breathability is formed from a mixture of a thermoplastic polymer and cavated filler particles such as cyclodextrin. The cavated filler particles provide the film with enhanced breathability to water vapor due to their ring-like, conical, cylindrical or otherwise hollow molecular structure, yet the film remains substantially impermeable to aqueous liquids. The enhanced breathability occasioned by the cavated particles permits the use of relatively low filler levels and correspondingly high polymer levels, thereby enhancing the film strength. The filler may melt during extrusion of the molten polymer into a film, facilitating smooth processing, and re-crystallize into particles after the film is formed and cooled.

International Classification:

B31F 112

US Classification:

156183, 162111, 162113, 264283, 442327

Abstract:

The present invention provides a one or two step method for bonding and creping or double creping a nonwoven web. In the method of the present invention, a nonwoven web is adhered to a creping roll and bonded while on the creping roll. The bonding of the nonwoven adheres the nonwoven to the creping roll in a pattern of the bonding roll. Once creped from the creping roll, the resulting nonwoven web is creped in the pattern of the bonding roll. The creped nonwoven webs of the present invention are useful in a wide variety of application including as wipes, liners, transfer or surge layers, outercovers, other fluid handling materials and looped fastener materials.

Abstract:

A multilayer, breathable film that contains a base layer and at least one skin layer is provided. The skin layer is incorporated with a filler that is capable of reducing odor. The base layer may be substantially free of the odor-reducing filler to maintain the integrity of the resulting film. As a result, it has been discovered that the multilayer film of the present invention can be used to reduce odor in a variety of applications, while still maintaining the desired breathability.

International Classification:

US Classification:

264103, 264211

Abstract:

A technique for incorporating a liquid additive into a nonwoven web is disclosed. Specifically, the liquid additive is loaded into filler particles to form a “dry liquid concentrate”, i. e. , pulverulent granular solid or powder loaded with the liquid additive. The incorporation of the liquid additive into dry liquid concentrates provides a variety of benefits. For example, prior to extrusion, the dry liquid concentrates generally retain the properties of filler particles from which they are formed as the liquid remains isolated. In this manner, a higher level of the liquid additive may be compounded with a melt-extrudable base composition without adversely affecting the extrusion process. Only upon extrusion of the composition will a significant portion of the liquid additive be released to provide the desired properties to the resulting nonwoven web.

International Classification:

B24D011/00

US Classification:

451/526000

Abstract:

A colored loop material suitable for use with a hook-and-loop fastening system, wherein the loop material includes a first fibrous nonwoven web having a first surface and a second surface and includes side by side bicomponent spunbond fibers in which the fibers have a melting point differential of at least about 15 C. and in which said bicomponent spunbond fibers are comprised of a polypropylene component including at between about 2% to 4% by weight of a coloring formulation, and a copolymer component. The first fibrous nonwoven web has a thickness of at least about 0.15 mm and a basis weight of at least about 20 grams per square meter; a pattern on the first surface thereof of continuous bonded areas defining a plurality of discrete unbonded areas formed by the application of heat and pressure, wherein individual fibers within the discrete unbonded areas have at least a portion thereof extending into and bonded within the continuous bonded areas; and a percent bonded area of from about 20 to about 50 percent. If desired, a film layer may be bonded to the second surface of the first fibrous nonwoven web. Alternatively, a second fibrous nonwoven web may be bonded or laminated to the second surface of the first fibrous nonwoven web. The loop material is particularly suitable for the preparation of a releasably attachable abrasive sheet material.

Abstract:

The present invention provides a method for creping a nonwoven web using a hot melt adhesive as the creping adhesive. As a second aspect of the present invention, an internal adhesive is added to the polymers used to produce the nonwoven web during the nonwoven web forming process and this internal adhesive adheres the nonwoven web to the creping roll. Using the processes of the present invention, more energy efficient methods are provided for creping nonwoven webs. The creped nonwoven webs of the present invention are useful in a wide variety of application including as wipes, liners, transfer or surge layers, outercovers, other fluid handling materials and looped attachment materials for hook and loop fasteners.
