Filed:

Dec 21, 2000

Appl. No.:

09/746355

Inventors:

Mario A. Perez - Burnsville MN
Betty Z. Mei - Woodbury MN
Michael D. Swan - St Germain en Laye, FR

Assignee:

3M Innovative Properties Company - Saint Paul MN

International Classification:

D01F 600

US Classification:

428359, 428397

Abstract:

Charged, high-strength, high-modulus, melt-processed microfibers, films having a charged, microfibrillated surface, and methods of making the same are described. Charged microfibrillated articles of the invention can be prepared by imparting fluid energy, typically in the form of high-pressure water jets, to a highly oriented, highly crystalline, melt processed film to liberate microfibers or microfibrous flakes therefrom. Microfibrillated articles of the invention find use as tape backings, in the preparation of woven or nonwoven articles, filters for particulate contaminants, such as face masks and water or air filters, fibrous mats, such as those used for removal of oil from water, wipes for dust or debris removal, and thermal and acoustical insulation.

International Classification:

B32B 1504

US Classification:

428343

Abstract:

This invention relates to an oriented embossed film, which may be used as a backing in an adhesive tape. The film is easily and readily hand-tearable without the use of cutting tools or a dispenser and provides a substantially straight, non-curling edge when torn.

International Classification:

B32B 300

US Classification:

4283155, 4283159, 4283166, 264 451, 429254

Abstract:

Microporous material comprising a polypropylene polymer having at least 20 percent crystallinity; and a compatible, amorphous, glassy polymer, wherein said polymers are miscible in a compound when heated above the melting temperature of the polypropylene polymer and wherein a polypropylene polymer phase separates from the compound when cooled below the crystallization temperature of the polypropylene polymer. Microporous material is made by a thermally induced phase separation process using a compound such as mineral oil to form one phase containing both polymers. The pores of the microporous material resist collapse during processing. Membranes made of this material are useful as battery separators having a good combination of strength, porosity, and ionic resistance when imbibed with an electrolyte.
