  • Publication number: 20020192449
    Abstract: The present invention relates to aliphatic polyester microfibers, films having a microfibrillated surface, and methods of making the same. Microfibers 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, aliphatic polyester film to liberate microfibers therefrom. Microfibrillated films of the invention find use as tape backings, 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 and those used as wipes, and thermal and acoustical insulation. Microfibers of the invention, when removed from the film matrix may be used in the preparation of woven or nonwoven articles and used as wipes for the removal of debris or dust from a surface. The microfibers and microfibrillated articles of the invention may be biodegradable, rendering them useful for geotextiles.

  • Patent number: 6461724
    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.

  • Publication number: 20010031594
    Abstract: A composite formed of a polymer matrix phase having a reinforcement phase including polymeric microfibers. The microfibers are preferably formed of a highly oriented polymer, having a high modulus value and a large surface area. The large surface area can serve to tightly bind the microfibers to the polymer matrix phase. The microfibers can be provided as a fully- or partially- microfibrillated film, as a non-woven web of entangled microfibers, or as a pulp having free fibers. The microfibers can be embedded in, or impregnated with, a polymer or polymer precursor. Some composite articles are formed from thermoset resins cured about a highly oriented polypropylene microfiber reinforcement phase, providing a strong, tough, moisture resistant article. One composite includes a matrix and reinforcement formed of the same material type and having substantially equal refractive indices, allowing the composite to be optically clear.
