Spacers are configured to be applied on the braid such that when in contact with each other form an annular cylinder having an external diameter selected to fit inside the sleeve. The spacers have a bevel at one longitudinal end. A substantially cylindrical insert has a bevel at one longitudinal end at substantially a same bevel angle as on the spacers. A diameter of the insert combined with twice the wall thickness of the braid is larger than an internal diameter the spacers. When axial tension is applied to the braid, the bevel on the insert with braid thereon laterally urges the spacers outward. The sleeve limits lateral outward movement of the spacers.

  • Publication number: 20110086224
    Abstract: A planar sheet comprises a plurality of polyamide yarns having a yarn modulus of from 3.7 to 6.8 N/dtex, an elongation to break of from 2.9 to 4.7% and a denier of from 130 to 15,000 and a plurality of steel wires wherein the steel wire is provided with a first crimp and a second crimp, the first crimp lying in a plane that is substantially different from the plane of the second crimp. The first and second crimp pitches and amplitudes of the steel wire are such that, when the steel wire and polyamide yarns are combined, the elongation to break of the wire is similar to that of the polyamide yarn. The wires and yarns are arranged such that they are oriented parallel to each other within the planar sheet. The sheet has utility in the construction of elastomeric components for tires and belts.

  • Patent number: 7914592
    Abstract: The present invention relates to the production of textiles and more particularly pertains to a method for manufacturing cotton towels comprising the steps of: combining a yarn of 120S combed long staple cotton and a yarn of 10S combed long staple cotton by means of a double winder and winding onto a bobbin or bobbins after combining; feeding the bobbin or bobbins of the combined yarn into a double twister for plying; winding the plied yarn onto a bobbin and weaving into greige; impregnating the greige in the solution of a combined desizing, scouring and bleaching machine to be soaked and steamed for removing the sizes and the impurities in the cotton yarn; treating the greige by means of deoxidization, dyeing, enzymatic desizing, softening, relaxation drying and sewing into towels. The present invention adopts the 120S combed long staple cotton for plying which achieves a definitive binding effect on the loosened fibers on the surfaces of the yarn, thereby forming fewer fluffs on the surfaces of the towel.

  • Patent number: 7810308
    Abstract: The invention relates to a method for producing a towel, specifically a low twist towel, comprising the following steps: Z twisting a thick yarn and separately Z twisting a fine count yarn; unevenly S twisting the Z-twisted yarns to make the volume of the thick yarn more than that of the fine count; weaving the yarn to produce a fabric; processing the fabric with hot water to reduce inner tension in the yarn and make the fabric become fluffy. Fabric produced by this method can solve the dependency on PVA, reduce energy consumption and material consumption, and prevent water pollution. This method for producing a low twist towel is environmentally friendly, healthy, and energy saving.

  • Publication number: 20100256326
    Abstract: A water-insoluble polyglutamic acid (PGA) fiber and a preparation method thereof are provided. In the preparation method, the PGA is cross-linked by a cross-linking agent and then passes through a spinning nozzle to form PGA fibers. Therefore, the highly water-absorbing PGA, which cannot be spun by conventional methods, can be spun to form PGA fibers and maintain the high water-absorption ability.
