  • Publication number: 20130273283
    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: Vehicular upholstery fabric is woven by using chenille yarn and multi-fiber yarn for weft yarns. The weaving interval between chenille yarns is set up less than the apparent thickness of the chenille yarn, which is specified as an observed value of the thickness. The apparent thickness of the multi-fiber yarn is less than one-fifth of the apparent thickness of the chenille yarn. There are tight portions where a great number of warp yarns passes over the chenille yarn, and rough portions, where a small number of warp yarns passes over the chenille yarn that is formed on the surface of fabric. PPT-fibers are used for the pile of the chenille yarn and the warp yarn.

    Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.

    Abstract: A composite prepreg material (10) with improved resistance to core crush and porosity incorporates a plurality of different fiber forms having varying cross-sectional configurations. Preferably, the fibers are interwoven in a warp (14) and fill (18) perpendicular orientation pattern. The varying cross-sectional configurations of the different fiber forms causes the fiber forms to have different levels of spreadability and frictional resistance to movement of the fiber. The present invention overcomes the susceptibility to many defects (specifically core crush and porosity) associated with composite material of a single fiber form having a set cross-sectional configuration, by incorporating multiple fiber forms having varying cross-sectional configurations. This multi-fiber form incorporation allows the strengths of one fiber form's properties to help compensate for the weaknesses of another fiber form's properties, and vice versa.

  • Publication number: 20030035919
    Abstract: Tuftable fabrics comprise a plurality of warp and weft tapes in a balanced construction of tapes with balanced dimensions of tapes in the warp and the weft and stabilization of the fabric to impart dimensional stability. The fabrics are useful as backings for tufted carpets and especially patterned carpets and carpet tile owing to a surprising combination of tuftability, resistance to edge curl and stability during tufting.

  • Publication number: 20020102894
    Abstract: A fabric for the forming, press and dryer sections of a paper machine, for use as a reinforcing base for a polymeric-resin-coated paper-processing belt or as a corrugator belt, or in other industrial settings where a material is being dewatered, is formed from a monofilament yarn, which is spirally wound in the form of a closed helix, adjacent turns thereof being abutted against and joined securely to one another. The monofilament yarn has a first side and a second side which are oppositely and correspondingly shaped, so that, when spirally wound in a plurality of turns, the first side fits closely into or against the second side of an adjacent and abutting turn, and adjacent spiral turns are secured to one another at the abutting first and second sides to form the fabric.

  • Publication number: 20010039158
    Abstract: A decorative outdoor fabric including a woven structure formed of warp effect yarns and at least some of the fill yarns comprising self-coating yarns formed of high melt and low melt yarn constituents. When the fabric is tentered, the low melt constituents melt and cross-flow to the other fibers in the fill and warp yarns. Both the warp yarns have deniers in the range of 50-4000 and the fill yarns have deniers in the range of 150-4000. Because of the cross-flow of the low melt constituents, the resulting fabric achieves acceptable abrasion resistance, stability, and load recovery and hand without the need for a latex backing.

  • Patent number: 6184161
    Abstract: The present invention relates to a method for manufacturing a three-dimensional textile product, characterized in that at least the pile thread of which is subjected to one or more of the following textile treatments: a) the textile thread is enveloped; b) several textile threads are added to the textile thread; c) the textile thread is structured by making use of at least one monofilament and at least one multifilament; d) the textile thread is structured by making use of at least one monofilament and at least one multifilament thread of thermoplastic fibres; e) each of the textile treatments mentioned in points a-d are performed under such circumstances that the textile thread is kept sufficiently flexible during a first textile treatment and can be stiffened in a subsequent treatment.
