  • Patent number: 11033078
    Abstract: The present invention is for a slip resistant shoelace comprising a shoelace tube and one or more friction inducing features such as a plurality of bumps made of rubber or silicone disposed over at least a portion of the length of the shoelace tube. The bumps can also be disposed over a rope in any desired manner to make it a slippage resistant rope. The plurality of bumps, when come in contact with each other or with any other surfaces in a tied knot, offer higher co-efficient of friction and thus resist slipping of the knot. A knot tied with the slip-resistant shoelace or the slip-resistant rope prevents slipping and prevents from getting loosened and untied inadvertently.

  • Patent number: 6260343
    Abstract: Strands and wire ropes composed of materials such as high carbon steels and stainless steels can be provided in a compacted, mechanically stress relieved and thermally stress relieved condition. The wires are compacted during stranding to form the individual strands of the wire ropes. The wires can be thermally stress relieved prior to stranding to remove tensile residual stresses. Compaction produces a compressive residual stress state in the strands which increases fatigue resistance. The strands can be thermally stress relieved subsequent to closing. The wires and strands can be heated using a process such as induction heating. The wire ropes can be torque balanced or rotation resistant. The wire ropes have high strength, a high strength-to-weight ratio and enhanced fatigue life. Stainless steel wire ropes also provide corrosion resistance.

  • Patent number: 4928464
    Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.

  • Patent number: 4724664
    Abstract: A method and apparatus for producing thread or yarn-like material by electrostatically flocking it or covering it with fibers. Grounded base or carrier threads that are provided with adhesive are moved through an electrostatic field of high voltage, where the surfaces of the carrier threads are flocked all the way around with pretreated short fibers (flock material). During the course of producing the flocked thread or yarn, selective lengths of the carrier threads are nonuniformly flocked in an irregular sequence, with the flock material, in different flock patterns.

  • Patent number: 4719744
    Abstract: Vacuum spinning of yarn produces yarns having good properties, and which may have a wide variety of different effects and constructions. A core filament yarn may be fed into operative association with a nipped sliver or roving, and then fed to a perforated rotating hollow shaft operatively connected to the vacuum. The core filament yarn may be a full stretched textured yarn, which is placed under tension and while under tension is dragged over a sharp edge of nonconductive material, and after the tension is relieved develops crimp. This causes individual fibers to be repelled, and provides for intermixing of the nipped sliver or roving fibers and the core filament yarn fibers. Alternatively, the filament yarn may be acted upon by draft rollers before the entrance to, and after the exit from, the hollow rotating shaft, to apply a force that breaks up to about 20% of the fibers. The yarns produced utilizing the broken fibers has a spun-like appearance.

  • Patent number: 4663927
    Abstract: A slub yarn, in which a sheath component is wound around a core component to form a plurality of slub portions along the axis of the yarn, which structure is obtained by simultaneously false-twist texturing the core and sheath components. The slub yarn has a feature that the slub portion includes a multilayered winding structure of seven or more layers of the sheath component wound around the core component. A method for producing the slub yarn includes a step of overfeeding a sheath component to a core component in the direction substantially perpendicular to a passage of the core component in a twisting zone of a false-twist texturing machine while the sheath component is guided by a guide repeatedly traversed along a passage of the core component, a distance between the guide and the passage of the core component being kept in a range not shorter than 10 cm. An apparatus for randomly traversing the sheath component along the core component during the false-twist texturing process is also provided.

  • Patent number: 4615167
    Abstract: A method and apparatus for forming a yarn or sewing thread from core and effect yarns. The effect yarn is drawn at no higher than a normal drawing ratio for material from which the effect yarn is made and the effect yarn is softened by sufficient heating, in order to prevent rupturing of the effect yarn during drawing. The core or effect yarn is passed through a wetting device to aid aspiration and entanglement of the core and effect yarns in a fluid jet device. The effect yarn is overfed to the jet device to aid in the formation of a highly entangled looped yarn which is subsequently set by a heated roller while contraction of the yarn is prevented. The core yarn can also be drawn at or below its normal drawing ratio in order to aid in developing thread tenacity and ensure an acceptable elongation at break after dyeing or subsequent wet processing.

  • Patent number: 4567720
    Abstract: A new process is provided for producing highly resilient, textured, continuous multifilament polymeric yarns and combinations of such yarns with other continuous filament yarns and with spun yarns. The unstable or wild loops which form in conventional air jet textured yarns are substantially eliminated in the product yarns of this invention. The product yarns are formed by continuously drawing polymeric yarn under controlled temperature conditions, texturing the yarn in an air jet texturizer and subjecting the textured yarn to saturated steam while restraining the linear shrinkage of the yarn in the presence of the steam, followed by continuous take-up of the yarn on a package.

  • Patent number: 4528809
    Abstract: Apparatus and method for making loop chenille type yarns and yarns produced thereby are disclosed. An elongated spindle having a tapered needle surface at one end thereof is provided. The spindle has a passage therein in communication with the needle surface for feeding a core thread to the needle surface. Effect thread is overfed to the needle location where a nose piece member cooperating with the needle aids in wrapping the effect thread about the needle to form loops. The binder yarn is fed to the needle and twisted about the core and effect threads. In a preferred embodiment, means are provided for reciprocating the nose piece relative to the needle between effect thread loop forming and effect thread non-loop forming dispositions. In this manner, "thick" and "thin" novelty yarns are provided in which the thick sections of the yarn comprise looped effect threads whereas the loops are not provided in the thin yarn sections.

  • Patent number: 4505100
    Abstract: A fasciated yarn, consisting of wholly aromatic polyamide fibers, which is excellent in mechanical properties, especially in creep durability in a high temperature atmosphere and is suitably utilized for industrial usage. The yarn can be produced by a method comprising the steps of: stretch-breaking a filament tow of the wholly polyamide fibers to form a staple fiber bundle and imparting a false-twist to the staple fiber bundle by a vortex while retaining parallelism of the staple fibers composing the bundle, thereby obtaining the fasciated yarn. Structural characteristics of the yarn reside in a mean fiber length in the range of from 150 mm to 600 mm, a crimpability of less than 5%, a mean degree of parallelism of less than 3.degree., and a number of wrap fiber groups in a range of from 0.5 to 20 per 1 cm in length of the yarn.

  • Patent number: RE31808
    Abstract: A method and apparatus for producing novelty yarn with an unusual configuration. An effect yarn is fed to a novelty yarn jet, and a core yarn is fed to a different yarn port in the same jet, the core yarn being maintained substantially taut. The combined core and effect novelty yarn is taken up from the jet and periodically (preferably pseudo-randomly) a pronounced variation in linear density is provided in the combined yarn. This linear density variation is accomplished by introducing a first fluid pulse into the jet at a first position to form a loop in the effect yarn, which loop extends substantially coincident with a portion of the core yarn, and then utilizing a second fluid pulse at a spaced position from the first pulse to impart a spiraling and/or rotating action to the loop of effect yarn to wind the effect yarn around the core yarn.
