    Abstract: Disclosed is a UV stabilized polyarylene sulfide composition, methods of forming the composition, and UV stabilized products that can be formed of the composition. The UV stabilized polyarylene sulfide composition can include a reactively functionalized polyarylene sulfide polymer in conjunction with a UV stabilizer. The reactivity of the polyarylene sulfide polymer is formed during melt processing via reaction of a reactively functionalized disulfide compound with a starting polyarylene sulfide. The reactivity of the polyarylene sulfide can encourage interaction between the polyarylene sulfide polymer and the UV stabilizer, which can improve dispersion of the UV stabilizer throughout the composition and improve miscibility between the polyarylene sulfide polymer and the UV stabilizer. Products can incorporate high concentrations of UV stabilizer and/or can be formed to very small cross sectional dimensions without phase separation between the UV stabilizer and the polyarylene sulfide.

    Abstract: A method produces a flat semi-finished product from a fiber composite material that contains individual carbon fibers, carbon fiber bundles, or a mixture thereof in a defined anisotropic fiber orientation and a thermoplastic matrix material. The anisotropy of the carbon fibers is created in a carding process using the high orientability of admixed non-carbon textile fibers, at least some of the non-carbon textile fibers being thermoplastic, and the carbon fibers having been isolated from waste or used parts. The flat fibrous web which is produced by a carding process and which has a specific orientation of the carbon fibers in the longitudinal direction is compressed into a sheet material under the effect of heat. This enables the use of carbon fibers, for example from production waste, as reinforcing fibers, whereby a less expensive raw material is provided and the carbon fibers are contained in the waste materials are recycled.

  • Patent number: 7578902
    Abstract: An apparatus and method for manufacturing a multi-layer web product. A long fiber stream is directed around a rotating carding cylinder. Two combing cylinders are disposed adjacent the carding cylinder to comb a first web of long fiber and a second web of long fiber, respectively, from the carding cylinder. A first conveyor receives the first web from the first combing cylinder and transports the first web toward a layering point. Similarly, a second conveyor receives the second web from the second combing cylinder and transports the second web toward the layering point. A short fiber deposition unit is disposed adjacent the second conveyor and deposits short fibers onto the second web. At the layering point, the first conveyor deposits the first web onto the second web, with the short fibers sandwiched therebetween, to form a layered web product.

  • Publication number: 20090094793
    Abstract: A drafting assembly for drafting a fibre web having upper and lower rear apron loops which have first and second support surfaces respectively being arranged to grip the card web fibres between them and transport the card web fibres from a rear entrance to a rear nip point on displacement of the rear aprons. Upper and lower front apron loops have third and fourth support surfaces, respectively, being arranged to grip the card web fibres between them and transport the card web fibres from a front nip point to an exit on displacement of the front aprons. The front and rear nip points are adjacent and arranged such that the front nip point receives card web fibres which exit the rear nip point. Proximate to the nip point, each loop is wedge shaped with the arms of the loop on each side of the nip point converging towards nip point and having an acute angle therebetween.

  • Patent number: 7503100
    Abstract: In a spinning preparation machine, a machine element lies opposite the clothing of a roller, bearing surfaces of end portions of the machine element are in engagement with respective bearing surfaces of stationary bearings, and an adjustment means is arranged in the region of each of the end portions and the bearings, the adjustment means being able to alter the radial spacing between the roller and the machine element. To enable the carding nip to be adapted or kept constant, adjusting elements of the machine element and adjusting elements of the bearings each have inclined bearing surfaces, and the machine element, in the event of undergoing thermally induced expansion in its longitudinal direction, is so displaceable along the inclined surfaces that the radial spacing remains the same.

    Abstract: In an apparatus on a spinning preparation machine, at least one machine element lies opposite and spaced apart from the clothing of a roller, and bearing surfaces of the end portions of the machine element are in engagement with respective bearing surfaces of stationary bearings. An adjustment means is arranged in the region of each of the end portions for altering the radial spacing between the clothing of the roller and the machine element. To enable the carding nip to be adapted or kept constant in the event of thermally induced changes in dimensions, the machine element and the bearings each have inclined bearing surfaces, and the machine element, in the event of undergoing thermally induced expansion in its longitudinal direction, is so displaceable along the sloping surfaces that the radial spacing remains the same.

  • Publication number: 20070220711
    Abstract: An apparatus is provided on a spinning preparation machine for adjusting the carding clearance. A clothed roller has a cylindrical peripheral surface and a cladding facing and spaced therefrom, wherein between the peripheral surface of the roller and a part of the cladding there is a carding region with a carding clearance where carding work is performed and carding heat is generated, heat leading to an alteration across the width of the machine in the contour of at least one of the components lying opposite each other. In order in simple manner to allow a uniform carding clearance under different production and processing conditions, the carding clearance can be made smaller by external energy input to at least one of the components facing each other and/or can be enlarged by throttling the energy input and the energy input.

    Abstract: An apparatus on a textile machine for cleaning fibre material has a first roller for conveying a travelling fibre web, and second and third rollers which have respective nips with one another and with the first roller on rotation of the three rollers. The second roller is arranged downstream of the third roller and co-operates with the first roller so that fibre is detached, the fibre is transferred to the nip with the third roller and conveyed by the third roller to the nip with the first roller. The rollers have clothing with tips which are inclined in the direction of rotation. To improve the cleaning the front angle a of the tips of the second roller is about from 10° to 50° and the clothing gaps may be large to obtain a higher filling volume for fibres.
