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 described in Spanish utility model U200601425 , and which describes a fabric in which the yarn of the weft is formed by an elastomer and the yarn of the warp is formed by a synthetic fiber.
  • the fabric comprises the elastomeric yarn with a 3-1-1/0-2-2// weave on the reed closest to the needles or first reed of a warp knitting machine, whereas in the second reed the synthetic fiber is arranged with a 1-2-1/1-0-1// weave, the yarning or weaving 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 of this invention has technical particularities making it especially suitable for manufacturing underwear garments, sportswear, garments that are comfortable to wear, swimwear, technical garments for their use in medical treatments and generally all those garments fitting tightly on the human body.
  • the weave 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.
  • These weaves also allow the elastane yarns and the synthetic fiber yarns to change in each loop the exit direction with respect to the entrance direction in the transverse direction, thus forming a hybrid mesh of extensible and resistant yarns with an improved tension.
  • These changes of direction of the fibers in the loops allow arranging the yarns from a horizontal entrance direction to a diagonal entrance direction and vice versa, both in upward diagonals and in downward diagonals with respect to the formation direction of the loops. This arrangement provides that the stress distribution in the diagonal direction is also benefited since the fabric has elastane yarns and synthetic fiber yarns also aligned in both diagonal directions.
  • the yarn of the weft is of a chlorine-resistant elastomer, for example, by means of a neutralization agent.
  • the fabric can optionally also comprise a silver salt coating on the fabric, with antibacterial and odor elimination functions, being adapted to the final needs and standards to be complied with or final use.
  • the fabric thus allows a more prolonged use in contact with the user's skin and can be used as swimwear, since its durability is increased but also since it does not allow the proliferation of bacteria and microorganisms responsible for body odor and of the garments as they are constantly wet.
  • the synthetic fiber yarn can comprise embedded therein microcapsules of delayed-release substances, such as aloe vera, anti-dust mite substances, anti-static substances and/or moisturizing substances.
  • delayed-release substances such as aloe vera, anti-dust mite substances, anti-static substances and/or moisturizing substances.
  • the garment made with this fabric thus also has cosmetic properties or anti-allergic advantages making it more comfortable to wear, according to its final use.
  • the fabric comprises added silver yarns, carbon fiber yarns and/or yarns of other materials incorporated among the synthetic yarns to confer antibacterial, static electricity conducting or heat insulating properties, according to its final use.
  • This allows defining the fabric as a technical fabric for professional uses where the garments must comply with functions apart from high comfort, or for its use in very demanding sports, in which the fabrics of the garments play a very important factor.
  • These added yarns can substitute part of the yarns of the second bar, without the elasticity of the fabric being reduced due to this.
  • the fabric comprises between 30% and 70% by weight of synthetic fiber yarn, although the percentage by weight is preferably 60% of the total.
  • the fabric in turn comprises between 30% and 70% by weight of elastomeric yarn, although the percentage by weight is preferably 40% of the total.
  • Said elastomer is mainly an elastane, such as Lycra ® or other trademarks such as Creora ®, Roica ®, etc, which allow a high longitudinal and transverse elasticity.
  • the yarn used is an elastane fiber 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 which can range from 11 to 210 deniers, with monofilament to multifilament and microfiber yarns.
  • This 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 elastane yarn (1) and a polyamide type synthetic fiber yarn (2), a microfiber yarn 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 transversely it has a yarn with a section perpendicular to said strands (3) of loops and a yarn with a section in each of the respective diagonals, said sections being alternately formed by the yarns (1 and 2), simultaneously providing the fabric with elasticity and resistance.
  • the fabric has the elastomeric yarn (1) in a bar of the weaving machine with a warp knit with a 3-1-1/0-2-2// 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 1-2-1/1-0-1// weave in this second reed, and an all full yarning.
  • This fabric has the synthetic fiber yarn (2) mainly arranged on one face and the elastane yarn (1) on the opposite face.
