  • Publication number: 20040121677
    Abstract: Textile fabric composed of synthetic fibers is subjected to a gas phase fluorination in a fluorine/inert gas atmosphere having a fluorine concentration in the range from 0.1 to 10% in order that the synthetic fiber surfaces may be activated in such a way that they are able to react with organic or inorganic compounds. Thereafter, the fabric is coated with a fluorocopolymer which is free of adhesion promoters. Similarly, yarn composed of synthetic fibers is first gas phase fluorinated and thereafter coated with a fluorocopolymer. Sewing yarn or thread, having been gas phase fluorinated, is bonded by means of a fluoropolymer coating. The improved adhesion makes the coated materials useful for a wide range of industrial applications. Textile fabric composed of synthetic fibers is subjected to a gas phase fluorination in a fluorine/inert gas atmosphere having a fluorine concentration in the range from 0.

  • Patent number: 6214094
    Abstract: The thermally stimulated discharge current of an electret article can be used to identify electret articles that exhibit superior filtration properties. Electret filters that exhibit superior properties not achieved in similarly constructed filters contain fibers that are made from a blend of a polymer and a performance-enhancing additive. The electret filters exhibit an initial detectable DOP penetration of less than 5% and an average Min@Chl of greater than 200 mg DOP as measured by DOP Filter Web Loading Test Procedure 1. These new electrets are particularly useful in a respirator.

  • Patent number: 6177365
    Abstract: This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. The first layer (base coat), being in contact with the airbag surface, comprises a non-silicone composition of at least one coating material, provides excellent adhesion, excellent tensile strength, and lower cost than standard silicone materials. The second layer, being a coating for the first layer, provides excellent reinforcement and aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.

  • Patent number: 6121165
    Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes and toilet tissue. These articles are essentially dry to the touch prior to use, but deliver liquid when subjected to in-use shear and compressive forces. In one aspect, the articles of the present invention comprise a carrier and an emulsion applied to the carrier, the emulsion comprising a continuous external nonpolar phase and an internal polar phase dispersed in the external nonpolar phase, wherein the article is capable of retaining fluid prior to use. In another aspect, the emulsion-treated articles exhibit improved ability to release fluid when subjected to in-use pressures. The articles of the present invention offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like) and wet-like toilet tissue.

  • Patent number: 6001749
    Abstract: A patterned conductive textile is provided by applying a finish to selected parts of a fabric which inhibits the formation of a conductive polymer coating on those areas. A conductive polymer is then oxidatively synthesized onto the remaining areas from an aqueous solution comprising the starting monomer, an oxidizing agent, and, optionally, a doping agent or counterion. The areas with the inhibitor finish remain substantially free of conductive polymer and a pattern of conductive and nonconductive areas is thus produced.
