Definitions

  • This invention relates to a woven or knitted fabric used for making various textile products such as bags, which enables strong bond strength to be achieved with heat boding yet with no need of sewing at least two woven or knitted fabric pieces.
  • the bonding of woven or knitted fabrics made of synthetic fibers having thermoplasticity is often carried out by conventional machine-sewing, except when thin woven or knitted fabrics not required to have strong bond strength are bonded together by a combined sealing and cutting technique.
  • Synthetic fibers of thermoplasticity are heat-bonded together with a temperature rise while they shrink by the action of heat. Therefore, when the temperature of a seal bar is kept higher than the heat-bonding temperature, no stable bonding of woven or knitted fabrics is achievable because they shrink concurrently upon coming into contact with the seal bar.
  • An object of the present invention is to provide a woven or knitted fabric which enables textile products having the necessary and sufficient bond strength to be fabricated by a heat-bonding technique while they are kept from shrinkage.
  • the present invention provides a woven or knitted fabric which is textured from at least two types of synthetic fiber yarns of thermoplasticity, between which there is a melting point difference of at least 20°C.
  • two or more types of yarns having a certain melting point difference are incorporated.
  • the sites of the woven or knitted fabric to be bonded together is heated under pressure at a temperature higher than the low melting point of one type of yarns and lower than the high melting point of the other type of yarns, the low-melting yarns melt to have bonding action while the high-melting yarns serve to keep the low-melting yarn from shrinkage that occurs within the period during which the low-melting yarns soften and finally melt, so that the bonded sites can be maintained constant in terms of dimensional stability.
  • the melting point difference of at least 20°C is here understood to define a temperature difference for keeping the high-melting yarns from softening and shrinkage when the woven or knitted fabric is heated under pressure at the low-melting temperature.
  • FIG. 1 shows the texture of one preferable woven or knitted fabric according to this invention.
  • FIG. 1 is a partly plan view of the texture of one embodiment of the woven or knitted fabric according to the present invention.
  • a woven or knitted fabric (A) is textured from yarns which vary in melting point.
  • the woven or knitted fabric is textured from warps (1), each consisting of 24 polyester (m.p.: 250°C) filaments of 50 deniers, and wefts (2), each consisting of polypropylene (m.p.: 160°C) filaments, say, 24 filaments of 50 deniers plus 24 filaments of 75 deniers.
  • the polypropylene wefts serve as an adhesive agent while he polyester warps remain intact.
  • warps (2') lower than in melting point than warps (1) and wefts (2) and warps (1) and wefts (2) may be used, either warps (1) or wefts (2) may be made of a material having a varying melting point.
  • a woven or knitted fabric textured from such yarns it is textured from warps, each consisting of one polyester filament of 20 denies, and wefts, each having a combined core and sheath structure consisting of 12 polyester filaments of 30 deniers, the latter being different in melting point from the former.
  • the melting point of the sheaths is lower than those of the warps and the cores of the wefts.
  • the sheaths of the wefts serve as an adhesive agent while the warps and the cores of the wefts remain intact.
  • FIG. 1 is directed to an example where one yarn is separated into a core and sheath for the purpose of illustration alone, it may be separated any desired parts or the like.
  • the woven or knitted fabric according to the present invention is textured from yarns varying in melting point, so that it can be heat-bonded while the yarns having a lower melting point are used as an adhesive agent.
  • the instant fabric is much more improved in terms of fabrication cost and time and, hence, operation efficiency, and so is best suited for products to be bonded at numerous sites, for instance, bags.
