Definitions

  • the present invention has been made in view of the above situations, and an object of the present invention is to provide a knitted fabric including a warp pattern section where the knitting yarns are bridged across in a substantially wale direction between the base knitted fabric sections spaced apart from each other, and a knitting method of the same.
  • the textile-like structure section is formed by a loop-shaped warp where the knitting yarn is bridged across in substantially the wale direction so as to be turned back to connect the base knitted fabric sections and a woof crossing the warp and appearing on the front and the back of the knitted fabric, so that a knitted fabric of a novel design with the textile-like structure section imitating a woven fabric can be obtained.
  • the knitting of the base knitted fabric section may be performed singularly or in combination of various types of knitting patterns such as plain knitting, rib, and purl knitting.
  • Each base knitted fabric section that exists in plurals may have the same color, pattern, or knitting structure, or may have a different color, pattern, or knitting structure.
  • the woof of the textile-like structure section is a knitting yarn extending in a direction of crossing the warp bridged across in substantially the wale direction.
  • the woof crosses the warp so as to appear at the front and the back of the warp at least one time each. That is, the warp and the woof of the textile-like structure section are in an crossing state similar to the crossing state of a vertical weaving yarn and a horizontal weaving yarn of the woven fabric.
  • the woof may be at least one, but is preferably in plurals so that the design of the textile-like structure section can be variously changed.
  • the woof can also adopt a yarn of the same type (same color) as or a different type (different color) from the warp.
  • the woof is preferably fixed so as not to detach from the warp as it is not knitted at the area crossing the warp.
  • the woof 52 is knitted and fixed to a waste knitted fabric 20 that is independently knitted at a position spaced apart in the knitting width direction from the knitted fabric 10 to be knitted (see Fig. 3 ).
  • the step of forming the temporarily-held knitting yarn is performed, with the stitch of the last course at the base knitted fabric section as the starting point, by bridging across the knitting yarn to the needle spaced apart in at least one direction of left or right from the starting point and returning to the starting point.
  • the knitting yarn is pulled out to at least one side in the transverse direction (course direction) of the needle bed from the starting point to form the temporarily-held knitting yarn, but after the knitting of the knitted fabric is finished, the turn-back unit (temporarily-held knitting yarn in knitting) is pulled to the lower side by the weight of one base knitted fabric section since one base knitted fabric section is on the bottom and the other base knitted fabric section is on the top, whereby the warp pattern section (warp) where the knitting yarn is bridged across in substantially the wale direction between the pair of base knitted fabric sections is formed.
  • warp warp
  • the knitting yarn is hooked to the needle spaced apart in the transverse direction from the distal end (end on the side spaced apart from the starting point) of the temporary knitted portion, and turned back towards the starting point side.
  • the temporary knitted portion is resolved by pulling the pair of base knitted fabric sections sandwiching the warp pattern section after the knitting of the knitted fabric is finished, and becomes part of the loop-shaped turn-back unit formed so as to be bridged across both the knitted fabric sections. According to such a method, the length of the temporarily-held knitting yarn can be obtained with the temporary knitted portion even if the spaced distance is relatively short, and thus the turn-back unit longer than the spaced distance can be formed.
  • the woof of the textile-like structure section is weaved between the warps described above using a "step of transferring temporarily-held knitting yarn” and a “step of feeding yarn between temporarily-held knitting yarns divided to the front and back needle beds".
  • the knitting yarn (woof) is fed between the temporarily-held knitting yarns held divided to the front and back needle beds, and such a woof is crossed with a plurality of warps lined in parallel in the course direction and sandwiched with the warps from the front side and the back side of the knitted fabric.
  • a twist may be formed in the warp pattern section including a plurality of turn-back units. That is, in the knitted fabric of the present invention, with the knitting yarn bridged across from the base knitted fabric section to another base knitted fabric section so as to be turned back to form a loop-shape as the turn-back unit, the base knitted fabric section side of the turn-back unit as the basal end, and the another base knitted fabric section side as the turn-back end, the lined order in the course direction of the plurality of turn-back units is preferably reversed for the basal end side and the turn-back end side.
  • a step of reversing the lined order of the basal end and the lined order of the turn-back end in the knitting width direction of a plurality of temporarily-held knitting yarns is suitably provided prior to knitting another base knitted fabric section with respect to the plurality of temporarily-held knitting yarns, where the starting point side of the temporarily-held knitting yarn is the basal end and the end on the opposite side of the basal end is the turn-back end.
  • a more specific method for reversing the lined order of the basal end and the lined order of the turn-back end in the knitting width direction of the temporarily-held knitting yarns includes a method of reversing the lined order when forming the temporarily-held knitting yarn and a method of reversing the lined order after forming the temporarily-held knitting yarn.
  • the temporarily-held knitting yarn from the starting point A is formed on the needle on the left side close to the starting point A, and the temporarily-held knitting yarns from the starting points B ... E are sequentially formed on the needles farther to the left side than the temporarily-held knitting yarn corresponding to the starting point A.
  • the length of each temporarily-held knitting yarn will not be even, but the lined order on the turn-back end side of the temporarily-held knitting yarn becomes E to A from left to right, whereby the warp pattern section with a twist can be formed.
  • the knitting method of the present invention may be performed with a two-bed flat knitting machine including a front needle bed and a back needle bed, in addition to being performed with a four-bed flat knitting machine.

  • the woof can be knitted without having the waste knitted fabric described above. Specifically, turning back the woof inserted between the warps so as to be hooked to the warp at the ends in the knitting width direction of the knitted fabric is repeated to knit the woof of the textile-like structure section with the woof of consecutive length. In this case, the crossing number of the warp and the woof becomes greater at both ends in the course direction of the textile-like structure section of the knitted fabric than at the intermediate part.
  • the number of times of transfer of a specific temporarily-held knitting yarn may be reduced by sequentially using two or three temporarily-held knitting yarns (e.g., temporarily-held knitting yarns of needles D and P in Fig. 15 ) near both ends in addition to the temporarily-held knitting yarns at both ends (temporarily-held knitting yarns of needles C and Q in Fig. 15 ).

  • the woof is inserted to the front knitted fabric section, and thereafter, the same woof is hooked to at least one of the warp at the end of the front knitted fabric section or the warp at the end of the back knitted fabric section and pulled back and then inserted to the back knitted fabric section.
  • the woof crosses the front and back knitted fabric sections as if short cutting.
  • the length of one round of the woof is shorter with respect to the peripheral length of the knitted fabric, and the region of the warp where the woof is not hooked from the area where the woof is hooked to the ends in the knitting width direction cannot be effectively used as a tubular portion. Therefore, the position of the warp to turn-back the woof is preferably four to five yarns worth, at most, from the ends in the knitting width direction.
  • the yarn feeder 8 is reciprocated more than once so as to transverse the knitted fabric to sandwich the woof between the temporarily-held knitting yarns held on the FB and the BB, similar to the knitting block 8.
  • the knitting blocks 7 to 10 are repeated for a plurality of times. According to the knitting blocks 7 to 10, the textile-like structure section 5 in which the warp 51 and the woof 52 cross in a lattice form as shown in Figs. 3 and 4 can be formed in the knitted fabric 10.
