Assignee:

Eastman Chemical Company - Kingsport TN

International Classification:

B29C 4904

US Classification:

264540, 264523, 264532, 264537, 26432818, 264349

Abstract:

The present invention relates to new polyester compositions, novel processes to prepare molded articles from these new polyester compositions, and novel containers fabricated from polyester/clay composites for food and beverages. The processing methods employed in this invention enable containers to be formed which exhibit excellent clarity. Specifically, the present invention relates to a process comprising forming a parison from a composite composition comprising about 0. 01 to about 25 weight % platelet particles dispersed in at least one polyester at a processing temperature which is at least 50Â above the Tg of said polyester; and molding said parison into a clear, thin walled article.

International Classification:

D02G 300

US Classification:

428397, 428357, 428400, 428401, 428480, 428482

Abstract:

The ability to transport body liquids in consumer products such as diapers, incontinents and feminine napkins is a key factor in their performance. This invention is designed to provide specific high fluxes (volume of liquid/(time*mass of polymer) of aqueous liquids in designated directions using bundles of new specially designed fibers. The key factors for the bundles are a high specific adhesion for the liquid of interest, a high specific volume of the bundle itself, and alignment of the fibers within the bundle. The invention includes novel liquid acquisition/distribution systems and absorbent products that include a liquid acquisition/distribution system which may incorporate the novel bundles of fibers.

International Classification:

A61F 1315

US Classification:

604370, 604372

Abstract:

The invention provides synthetic polymeric fibers which have utility as temporary acquisition/distribution absorbent structures and permanent storage/distribution absorbent structures in a wide range of absorbent products such as diapers, feminine napkins, and adult incontinent pads. These fibers are short, highly distorted, and bulky characterized by lengths between 2 and 37 mm, short-range distortion factors between 5 and 70, long-range distortion factors between 0. 05 and 0. 9, and single fiber bulk factors between 0. 5 and 10. They may or may not have capillary channels on the surface. The advantages of these materials are their increased absorbency, reduced wet collapse at low densities, reduced rewet, reduced loss of liquid under pressure, and their ability to be desorbed by distribution materials such as capillary channeled fibers or by conventional storage materials such as fluff pulp or superabsorbent polymer fiber or powder.

Abstract:

This invention relates to novel multilayer formed articles including, but not limited to containers such as bottles, tubes, pipes, preforms and films (including oriented films such as biaxially oriented) comprising a melt processible resin having dispersed therein a platelet filler. The multilayer formed articles have improved barrier while maintaining excellent clarity. More particularly, the multilayer structures of the present invention display haze values of less than about 2% and carrier resins which are substantially free from platelet particles having a diameter greater than about 15 microns.
