    Abstract: The invention relates to a food casing with textile backing material which has been coated with a layer of regenerated or precipitated cellulose. This casing combines the properties of a textile skin with those of a cellulose fiber skin. Besides the surface texture for which textile skins are known and prized, it also has the transparency and the barrier properties, i.e. water-vapor permeability, oxygen permeability and smoke-constituent permeability, of a cellulose fiber skin. At the same time the casing is impervious to fat. It is used preferably as an artificial sausage casing.

  • Patent number: 7632764
    Abstract: The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.

    Abstract: Organic inherently conductive polymers, such as those based on polyaniline, polypyrrole and polythiophene, are formed in situ onto polymeric surfaces that are chemically activated to bond, ionically, the conductive polymers to the substrates. The polymeric substrate is preferably a preshaped or preformed thermoplastic film, fabric, tube, or a medical device for tissue repair regeneration and/or replacement, although other forms of thermoplastic and thermoset polymers can be used as the substrates for pretreatment using, most preferably, C-succinylation-based processes followed by exposure to an oxidatively polymerizable compound capable of forming an electrically conductive polymer. The resultant conductive surface imparts unique properties to the substrates and allows their use in antistatic clothing, surface conducting films for electronic components and the like, and electromagnetic interference shielding for civilian and military installations as well as implantable medical devices.

    Abstract: A method for manufacturing an artificial leather comprises the following steps. First, ultramicrofiber-forming fibers having an islands-in-sea type cross-sectional configuration are formed by blend spinning or conjugate spinning. Secondly, a porous reinforcement sheet of low compactness is formed from polyester, polyurethane or polyolefin by spunbonding, meltblowing or calendering. Next, the ultramicrofibers are entangled with the reinforcement sheet by needle punching or spunlace to form the complex reinforced ultramicrofiber nonwoven fabric. The nonwoven is impregnated or coated with an elastomer resin composition, and then subjected to a coagulating process, a washing process, a drying process and a removing process to produce a semi-product leather. Finally, the semi-product leather is then processed to produce the artificial leather.

  • Publication number: 20040116026
    Abstract: A resin charged media can be a single or layered construction needled together to provide a graded-density structure of fine fibers intermixed with finer fibers. This resulting media possesses a higher particulate loading retention capability, particularly early in the filtration cycle, relative to other cellulose, spun-bonds, or other similar materials commonly applied to filtration applications where filtration is predominantly a surface-loading phenomenon. The filtration media provides for depth filtration with the multi-layered needled layers, thereby enhancing the overall particulate-holding capacity of the charged media. This results in more resistance to fine particulates and improvements in efficiency due to increased sub-micron particle loading. With the filter media consisting of a graded structure, surface loading phenomenon can be reduced and filter life improved. Since the layers in the media are physically combined using needling technology, they will not separate.

  • Publication number: 20040034942
    Abstract: A process for drying/heat-treating nonwoven webs in which the web is partially dried under tension in a first drying zone and further heat treated under low tension or in a substantially tensionless state a second drying zone. The process significantly reduces the occurrence of stretch-type defects in the nonwoven webs.

  • Patent number: 6638579
    Abstract: A paper machine substrate modified to resist contamination by adhesive materials. The paper machine substrate includes: a paper machine substrate; and an active agent that is grafted to the surface of the paper machine substrate to lower the surface energy of the paper machine substrate so that the substrate resists contamination by adhesive material. The papermachine substrate may be made by a process that includes the steps of: providing a paper machine substrate; applying an active agent to the paper machine substrate; and exposing the paper machine substrate to greater than about 2 million rads (Mrad) of radiation to cause a reaction between the active agent and the substrate so the active agent becomes joined to the substrate. The active agent may be a fluorinated monomer, a fluorinated polymer, a perfluorinated polymers, or a polyalkyl siloxane.

  • Publication number: 20030109187
    Abstract: A landscaping fabric that includes a pesticide is made by extruding molten polypropylene from a plurality of holes to generate filaments. The filaments are cooled and drawn to cause the filaments to become reduced in diameter. The filaments are distributed onto a belt to form a mat and the mat is compressed to bond the filaments into a nonwoven fabric. An insecticide is applied to the nonwoven fabric and the nonwoven fabric and insecticide combination is dried.
