Definitions

  • the present invention relates to a warp knit fabric with synthetic fiber and elastomeric yarns.
  • the fabrics must provide different qualities such that they allow an ease in manufacturing the garments and subsequently a better maintenance.
  • the fabrics are preferably made by means of warp knitting to achieve a greater elasticity.
  • Garments incorporating synthetic fibers thus allow laser cutting and ultrasound welding, thus preventing uncomfortable seams.
  • these garments have a certain tendency to roll up at their selvedges or edges, such that the movement of the user's body forms cords or small rolls causing certain discomfort.
  • the garments made with mixtures of natural fibers and elastomers do not have a correct lightness finish and have problems of adaptability to the body compared to previous fabrics of synthetic fibers as they are looser.
  • An example of elastic fabric which is more suitably adapted to the configuration of the body is that describing a fabric in which one yarn is formed by an elastomer and the other yarn is formed by a synthetic fiber.
  • the fabric comprises the elastomeric yarn with a 2-0-1/1-3-2// weave for closed mesh or 0-2-2/3-1-1// for open mesh of the same weave on the reed closest to the needles of a warp knitting machine, whereas in the second reed the synthetic yarn is arranged with a 2-4-3/2-0-1// weave for closed mesh or 4-2-2/0-2-2// for open mesh, the yarning for both yarns being of the all full type.
  • the synthetic fiber yarn is thus on one face of the fabric, making a certain plating, and the elastomeric yarn is on the other face of the fabric, such that said construction prevents said fabric from being able to roll up when it is tensed or stretched on the user's skin.
  • the elastic fabric object of this invention has technical particularities making it especially suitable for manufacturing underwear garments, sportswear, garments that are comfortable to wear, control wear, swimwear, technical garments for their use in medical treatments, garments for protecting muscles and generally all those garments fitting tightly on the human body.
  • the weave between the elastomeric yarns and the synthetic fiber yarns of the fabric forms parallel and resistant four-yarn strands by means of consecutive loops in a longitudinal direction of the fabric, these strands being configured by the two parallel yarns and the turn thereof, the elastomeric yarns and the synthetic fiber yarns being arranged in the diagonal direction, changing in each loop the exit direction with respect to the entrance direction, thus forming a hybrid mesh of extensible and resistant yarns with an improved tension from an inclined entrance direction to an oblique exit direction and vice versa, both in upward diagonals and in downward diagonals with respect to the formation direction of the loops, the fabric having elastomeric yarns and synthetic fiber yarns also aligned in both diagonal directions.
  • This arrangement provides that the stress distribution in the diagonal direction is also benefited since the fabric has elastomeric yarns and synthetic fiber yarns also aligned in both diagonal directions.
  • the fabric comprises from 30% to 70% by weight of synthetic fiber yarn.
  • the fabric in turn comprises from 30% to 70% by weight of elastomeric yarn.
  • the fabric comprises 57% by weight of synthetic fiber yarn and 43% by weight of elastomeric yarn.
  • Said elastomer is mainly an elastane fiber, such as Lycra ® or other trademarks such as Creora ®, Roica ®, etc., which allows a high longitudinal and transverse elasticity.
  • the yarn used is an elastane fiber with a density between 11 and 210 deniers.
  • the synthetic fiber yarn used is preferably a polyamide fiber, such as polyamide PA6, PA66, PES or other synthetic fibers, the density of which comprises from 11 to 210 deniers, with monofilament to multifilament and microfiber yarns.
  • the synthetic fiber together with elastane allows the fabric to be handled with the most modern technologies, allowing the laser cutting of the fabric and its welding by means of ultrasound, thus allowing making multi-piece garments without conventional seams, which lead to a loss of elasticity and comfort of the piece or garment that do not occur in a garment the parts of which are joined by welding.
  • the fabric is formed by a warp knit with an elastomeric yarn (1), in this case a Lycra® type elastane, and a synthetic fiber yarn (2), polyamide in this case.
  • elastomeric yarn (1) in this case a Lycra® type elastane
  • synthetic fiber yarn (2) polyamide in this case.
  • Figure 1 shows how the yarns (1 and 2) are woven in a series of consecutive loops in a longitudinal direction, forming resistant four-yarn strands (3), whereas diagonally the yarns (1 and 2) are arranged alternately between the synthetic fiber yarn (2) and the elastomeric yarn (1).
  • the yarns (1 and 2) entering in a diagonal direction exit in the other oblique direction, the fabric being formed such that the synthetic fiber yarn (2) is arranged on one face thereof, and the elastane yarn (1) is arranged on the other face.
  • the fabric has the elastomeric yarn (1) in a bar of the weaving machine with a warp knit with a 2-0-1/1-3-2// weave in the first reed of the machine, and with an all full yarning, whereas the yarn (2) is arranged in the second reed of the machine, with a 2-4-3/2-0-1// weave in this second reed, and an all full yarning, forming an open mesh.
