  • Braiding offers many advantages over knitting or weaving such as, for example, the reduction of frictional forces applied to the yarns used in the creation of the braided structure, the ability to use high denier yarns (e.g., between 800D to 20000D, between 1000D to 10000D, between 1000D to 5000D, and the like), the ability to combine different types of yarns with non-yarn materials such as, for example, rubber strands, ropes, metals, and the like.
  • high denier yarns e.g., between 800D to 20000D, between 1000D to 10000D, between 1000D to 5000D, and the like
  • non-yarn materials such as, for example, rubber strands, ropes, metals, and the like.
  • Braiding is a process of interlacing or interweaving three or more yams diagonally to a product axis in order to obtain a thicker, wider or stronger product or in order to cover (overbraid) some profile.
  • Interlacing diagonally means that the yarns make an angle with the product axis, which can be between 1° and 89° but is usually in the range of 30° - 80°. This angle is called the braiding angle.
  • Braids can be linear products (ropes), hollow tubular shells or solid articles (one, two or three-dimensional textiles) with constant or variable cross-section, and of closed or open appearance.
  • the yarns, filaments, or other materials used for braiding may be formed of different materials having different properties.
  • the properties that a particular yarn or other will impart to an area of a braided component partially depend upon the materials that form the yarn.
  • Cotton for example, provides a softer product, natural aesthetics, and biodegradability.
  • Elastane and stretch polyester each provide substantial stretchability and fast recovery, with stretch polyester also providing recyclability.
  • Rayon provides high luster and moisture absorption.
  • Wool provides high moisture absorption in addition to having insulating properties and biodegradability.
  • Nylon is a durable and abrasion-resistant material with relatively high strength.
  • Polyester is a hydrophobic material that also provides relatively high durability.
  • a yarn may be a monofilament or a multifilament.
  • the yarn may also include separate filaments that are each formed of different materials.
  • the yam may include filaments that are each formed of two or more different materials, such as a bicomponent yarn with filaments having a sheath- core configuration or two halves formed of different materials.
  • braided articles can be formed as tubular braids on a braiding machine.
  • Different types of braiding machines such as a radial, axial or lace are available.
  • One example of a lace braiding machine can be found in Ichikawa, EP 1 486 601, granted May 9, 2007 entitled“Torchon Lace Machine” and EP No. 2 657 384, published Oct. 30, 2013 entitled “Torchon Lace Machine,” the entirety of which are hereby incorporated by reference.
  • the upper portion of an exemplary braiding machine 10 is shown in FIG. 1.
  • Braiding machine 10 includes a plurality of spools 12. In some embodiments, the spools 12 carry the yarn 14 selected for braiding.
  • the yarns 14 from individual spools are selectively interlaced or intertwined with one another by the braiding machine 10. This interlacing or intertwining of strands forms a braided article 16, as further described below.
  • Each of the spools 12 is supported and constrained by a track 18 about the circumference of the braiding machine 10.
  • Each spool 12 has a tensioner 20 (shown schematically in FIG. 1) that operates, along with a roller 22, to maintain a desired tension in the yarns 14 and the braided article 16.
  • a tensioner 20 shown schematically in FIG. 1
  • the braiding point is defined as the point or area where yams 14 consolidate to form braided article 16.
  • the distance between yarns 14 from different spools 12 diminishes. As the distance between yarns 14 is reduced, the yarns 14 intermesh (i.e. interlace) or braid with one another in a tighter fashion and are pulled linearly by roller 22.
  • each spool 12 is carried and supported by a carriage 26.
  • Each spool 12 is movable about the circumference of the track 18 by rotor metals 28.
  • each of the rotor metals 28 can be moved clockwise or counterclockwise.
  • each rotor metal is not intermeshed with the adjacent rotor metal. Instead, each rotor metal 28 may be selectively independently movable. As can be seen by comparing FIG. 3 to FIG.
  • the braiding machine 10 is programmable such that the individual rotor metals 28 rotate the carriages 26, and thus the spools 12 to move them about the circumference of the track 18.
  • the yams 14 carried on the spools 12 interlace to create a desired braid pattern.
  • the movement of spools 12 may be pre-programmed to form particular shapes, designs, and to specify thread densities of a braided component or portions of a braided component.
  • Such an exemplary braiding machine may form intricate braid configurations including both jacquard and non-jacquard braid configurations or geometries. Such configurations and geometries offer design possibilities beyond those offered by other textiles, such as knitting or weaving.
  • the size of braiding machine 10 may be varied. It should be understood that the braiding machine 10 shown and described is for illustrative purposes only. In some aspects, braiding machine 10 may be able to accept, for example, 144 carriages, although other sizes of braiding machines, carrying different numbers of carriages and spools is possible and is within the scope of this disclosure. By varying the number of carriages and spools within a braiding machine, the density of the braided articles as well as the size of the braided component may be altered.
