  • Patent number: 10399114
    Abstract: A tow prepreg manufacturing apparatus applies resin to an original tow of reinforcing fibers. The tow prepreg manufacturing apparatus includes an oiling roller, a scraper, a resin reservoir, a tube pump, and a controller. The oiling roller is supplied with resin while rotating at a predetermined rotation speed. The scraper adjusts the shape of the resin supplied onto the oiling roller. The resin reservoir supplies resin to the oiling roller. The tube pump discharges resin to the resin reservoir. The controller controls the tube pump so that the amount of resin held in the resin reservoir remains constant and controls the rotation speed of the oiling roller so that a resin content of a wound tow prepreg becomes equal to a target resin content.

  • Publication number: 20120156485
    Abstract: A hollow fiber membrane is made by covering a tubular supporting structure with a membrane dope and converting the membrane dope into a solid porous membrane wall. Optionally, a textile reinforcing structure in the form of a circular knit may be added around the supporting structure before it is covered in dope. The reinforcing structure thereby becomes embedded in the membrane wall. The supporting structure may be soluble in a non-solvent of the membrane wall, for example water, and may be removed from the membrane. Alternatively, the supporting structure may be porous. A porous supporting structure may be made by a non-woven textile process, a sintering process within an extrusion machine, or by extruding a polymer mixed with a second component. The second component may be a soluble solid or liquid, a super-critical gas, or a second polymer that does not react with the first polymer.

  • Patent number: 7687111
    Abstract: In a method for structuring the surface of a substrate, a substrate is elastically expanded by the application of a tensile stress so that a surface area of the substrate in which a structure is to be created, is enlarged. Then, in the surface area, a structure is produced that is larger than the structure to be produced. For this purpose at least one solution is applied to the substrate, which solvent contains at least one solid substance dissolved in a solvent. The solvent is then removed from the surface of the substrate so that the solid substance remains behind. The expansion of the substrate is at least partly reversed by the reduction or removal of the tensile stress so that the size of the structure is reduced to the size of the structure to be produced. In the material of the substrate, a compression stress can also be created to reduce the size of the structure to the size of the structure to be produced.

  • Patent number: 6598276
    Abstract: Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form, bonded web body and hook-engageable, free-standing loops extending from the web body. The product is, in important cases, stretched before bonding to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In important cases a binder is added to stabilize the product in its stretched condition. An example of the loop product is produced by needle-punching a batt of staple fibers in multiple needle-punching operations, applying a foamed acrylic binder, and then stretching the needled batt and curing the binder with the batt stretched. Other forming techniques are disclosed and several novel articles employing such loop products are described.

    Abstract: The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structures; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods. Moreover, the uncured or at most, semi-cured, polymer composition applied to the base substrate ensures that the substrate maintains maximum flexibility for subsequent shaping into composite articles prior to curing. The methods described herein produce multiple layer composite articles that are lighter, stronger, more flexible and utilize less material, than composite articles produced by conventional techniques.

  • Patent number: 5068000
    Abstract: A process for the production of bias-oriented reinforcing fabrics for the manufacture of power transmission belts, hoses and the like. The fabric is initially woven on a high speed, flat shuttleless loom, then immersed in a warm liquid solution to soften the sizing. The fabric is then processed to displace one selvedge longitudinally relative to the other, to achieve the desired bias angle of the weft yarns, usually about 120/60.degree. to the warp yarns. After partial drying, and fine adjustment of bias angle in a weft straightener, the fabric is gripped at its selvedges by a clip tenter and retained with the desired bias orientation while being dried. The dry fabric is substantially stabilized in its desired bias orientation. The selvedge edges are then trimmed off hot knives and the trimmed fabric is collected on a roll for shipment to and use by the belt/hose manufacturer, where it is calendered with a rubber compound and banner cut into rhomboid-like sections.

    Abstract: An elastomer coated bias fabric for reinforcing power transmission belts and the like is disclosed wherein one surface of the fabric is provided with an uncured, tacky, elastomeric composition. The fabric is prepared by pre-impregnating the fabric, transversely stretching the fabric on a tenter frame, coating a latex composition on both surfaces of the fabric while maintaining the fabric in its transversely stretched condition, and after drying the fabric, overcoating one surface only of the coated fabric with a tackified, latex composition which may contain a chemical linking agent which enhances the bond between the elastomer and the fabric by forming a chemical bridge between them. A method for manufacturing coated fabric is also disclosed.

  • Patent number: 4751143
    Abstract: The aging period for chemically stabilized, adhesive activated polyester material can be reduced by contacting the material before it is substantially drawn or stretched with a composition containing a defined epoxide compound catalyzed with ions of at least one of potassium, cesium, rubidium or ammonium at a pH of between about 7.5 to about 13.0. The composition preferably also contains chloride, bromide or iodide ions which stabilizes the pH and/or an amine which improves adhesion to rubber.

  • Patent number: 4643916
    Abstract: A method for manufacturing a pressure belt for use with an extended nip press in a paper making machine. The belt is characterized by a base fabric formed of a synthetic fiber filament, and formed with a synthetic resin layer on each outer and inner peripheral side thereof. The outer peripheral side which becomes in contact with the felt is provided with a number of drain channels. In the method of manufacturing, a base fabric in the form of an endless belt is trained around a heating cylinder, guide rolls and stretching rolls. The outer peripheral surface of the base fabric is coated with a curable synthetic resin as the fabric is moved. The layer of synthetic resin is semi-cured by heating means including the heating cylinder. This process of coating and semi-curing is repeated until desired thickness of the resin layer is obtained. Drain channels are then formed in the semi-cured resin by an embossed roll whereupon the resin layer is cured and then ground to provide a desired thickness.
