US Patent:

6586073, Jul 1, 2003
Filed:

Sep 20, 2001
Appl. No.:

09/957405
Inventors:

Mario A. Perez - Burnsville MN
Sundaravel Damodaran - Maplewood MN
Michael D. Swan - St. Germain en Laye, FR
Assignee:

3M Innovative Properties Company - St. Paul MN
International Classification:

B32B 524
US Classification:

428141, 428143, 428147, 428152, 428155, 428910, 428213, 428220, 442408, 264504, 264442, 2642888, 2642902
Abstract:

Fibers and microfibrillated articles are provided by imparting fluid energy to at least one surface of a highly oriented, voided, melt-processed polymeric film. The fibers and microfibrillated articles are useful as tape backings, filters, thermal and acoustical insulation and as reinforcement fibers for polymers or cast building materials such as concrete.

US Patent:

7001475, Feb 21, 2006
Filed:

Dec 11, 2001
Appl. No.:

10/016544
Inventors:

Ronald Wayne Ausen - St. Paul MN, US
Sundaravel Damodaran - Maplewood MN, US
Hak-Rhim Han - Newport MN, US
David Wayne Hegdahl - White Bear Lake MN, US
Assignee:

3M Innovative Properties Company - St. Paul MN
International Classification:

B32B 31/00
B32B 31/14
B32B 31/30
US Classification:

156229, 156250, 156252, 156253, 156256, 156257, 156295
Abstract:

A method of making a three-dimensional film structure having controllable contact properties comprises making separable surface elements on a top portion of a film structure and stretching the film structure to separate the separable surface elements, thereby obtaining a desired surface structure which delivers a certain contact property such as a pressure sensitive adhesive property. The separable surface elements are provided using a cut film surface, a stemmed film, or a layer of particles.
