Definitions

  • the present invention relates to a method of forming a widening stitch on an inner side from the end in a knitting width direction of a knitted fabric when knitting a knitted fabric with a flat knitting machine, and a knitted fabric formed with such widening stitch.
  • One method is a method of forming a new stitch on an empty needle positioned on the outer side of the stitch at the end of the front knitted fabric part or the back knitted fabric part in the knitting width direction to increase the knitting width (hereinafter referred to as outer widening).
  • the other method is a method of forming a new stitch on an empty needle in a knitting region of the knitted fabric made by moving the stitches of a plurality of wales at the end of the knitted fabric in the knitting width direction to the outer side to increase the knitting width (hereinafter referred to as inner widening).
  • a new wale is formed at the edge of the knitted fabric in the knitting width direction every time a widening stitch is formed in the outer widening, the edge of the knitted fabric becomes uneven, and the outer appearance becomes unsatisfactory.
  • a new wale is formed at a location other than at the edge of the knitted fabric, and thus wales formed in a series appear at the edge of the knitted fabric, and the wales with the boundary line of the front and back knitted fabric parts in between are formed in a parallel and even state.
  • the widening stitch is formed by feeding a knitting yarn to an empty needle on which the stitches of the previous course do not exist. Therefore, a newly formed stitch is pulled up by the stitch of the next course at the location formed with the widening stitch, whereby a large hole forms at the location formed with the widening stitch, and the appearance degrades.
  • the applicant of the invention has proposed a method of forming a widening stitch through inner widening so that the hole formed at the location formed with the widening stitch is less likely to stand out (see patent document 2).
  • This widening stitch forming method first feeds the knitting yarn to a first needle while transferring the stitch held on the first needle to a second needle where the first needle and the second needle are arranged facing each other on front and back needle beds respectively, and forming a new stitch on the first needle in continuation to the stitch transferred to the second needle.
  • the stitch transferred to the second needle becomes the widening stitch as a result of forming the new stitch on the first needle.
  • the stitch transferred to the second needle is transferred to the relevant empty needle, so that the widening stitch is formed next to the stitches held on the first needle.
  • the widening stitch is formed using transfer between the needles arranged on the different front and back needle beds, and the stitch is split into two to form the widening stitch (hereinafter referred to as split knitting).
  • the widening stitch When forming the widening stitch by split knitting, the widening stitch will be held at the stitch of the previous course, and thus will not be pulled up by the stitch of the next course.
  • the knitted fabric having a widening stitch with a very small hole opening is thereby knitted, and the knitted fabric of satisfactory outer appearance is obtained.
  • a method of knitting a knitted fabric of the present invention is a method of forming a widening stitch on an inner side from an end of a knitted fabric in a knitting width direction with a flat knitting machine having at least a pair of front and back needle beds, at least either of which is capable of being racked in a transverse direction so that stitches can be transferred between the front and back needle beds, wherein the widening stitch is formed according to the following steps.
  • the steps include:
  • the step of knitting a next course from one end to the other end of the knitting region while missing the knitting needle holding the stitch transferred in step a out of the stitches transferred in step d is preferably performed at least once in continuation to step d described above.
  • the method of forming the widening stitch of the present invention preferably includes, between step b and step c, a step of knitting a next course from one end to the other end of the knitting region on the previous course including the hooked loop hooked by step b on the knitting needle on which the widening stitch is to be formed.
  • the method of forming the widening stitch of the present invention can be applied to a case where a first yarn feeder and a second yarn feeder are arranged in the flat knitting machine, and the widening stitch is formed on the inner side from the end of the knitted fabric in the knitting width direction by performing a double system knitting using the two yarn feeders.
  • the knitted fabric is preferably knitted to a tubular form.
  • the two knitting yarns tend to cross at one end in the knitting width direction that becomes an inverting position in the traveling direction of the yarn feeders if knitting is performed to a tubular form with the preceding first yarn feeder 6 being arranged on the far side and the following second yarn feeder 5 being arranged on the near side when seen from the front side of the knitting machine, as shown in Fig. 9 .
  • the knitting yarn is pulled by the surrounding stitches, and a hole g as shown in Fig. 10 forms at the boundary X of the front and back knitted fabric parts.
  • knitting is performed such that the hole at the crossing portion hardly stand out, but a hole still exists in the knitted fabric although the hole is less likely to stand out.
  • the method of forming the widening stitch of the present invention preferably forms a boundary wale, which serves as a boundary of a front knitted fabric part and a back knitted fabric part when forming the widening stitch while knitting the knitted fabric to a tubular form by double system knitting.
  • the boundary wale is formed by continuously forming stitches by twisting the stitches, and winding a knitting yarn different from the knitting yarn forming the twisted stitch on the twisted stitch, whereby a hole does not form at the crossing portion of the yarns.
  • the knitted fabric formed with a widening stitch on the inner side from the end of the knitted fabric in the knitting width direction includes a widening stitch formed by feeding a knitting yarn to a hook of a knitting needle which is empty as a result of transferring the stitch already held on the knitting needle on which a widening stitch is to be formed to the opposing needle bed.
  • the knitted fabric formed with the above-described method includes a stitch hidden between the widening stitch and a stitch adjacent to the widening stitch, which was transferred to the opposing needle bed, wherein a new stitch is formed on the hidden stitch.
  • the knitted fabric formed with the widening stitch on the inner side from the end of the knitted fabric in the knitting width direction of the present invention is preferably a tubular knitted fabric.
  • a stitch is formed in advance on the knitting needle on which a widening stitch is to be formed, the stitch is transferred to the opposing needle bed, a widening stitch is formed on the relevant knitting needle which became empty as a result of the transfer, and then the transferred stitch is returned next to the widening stitch.
  • the widening stitch is not formed by splitting the already formed stitch into two, and thus the widening stitch can be easily knitted and the load on the yarn becomes small even when knitting with a yarn that easily breaks or knitting at a small mesh.
  • step d the next course is knitted from one end to the other end of the knitting region while missing the knitting needle holding the stitch transferred in step a, and thus a new stitch on the stitch transferred in step a is formed in the course after the course in which the knitting needle is missed.
  • the stitch transferred in step a is pulled up by the newly formed stitch, and the hole formed at the location formed with the widening stitch becomes more unlikely to stand out.
  • step a When the next course is knitted on the hooked loop hooked on the empty needle at between step b and step c, a new stitch is formed on the stitch transferred in step a and the stitch transferred in step a is pulled up. Accordingly, the hole formed at the location formed with the widening stitch becomes more unlikely to stand out.
  • the method of forming the widening stitch of the present invention enables knitting for two courses as well as transferring of stitches while a carriage mounted with a plurality of knitting systems travels one course when the widening stitches are formed while knitting is performed in a double system.
  • the productivity enhances while easily forming the widening stitch so as not to form a large hole at the location formed with the widening stitch.
  • the productivity enhances by knitting the knitted fabric into a tubular form.
  • a hole that was formed conventionally does not form if the boundary wale, which serves as the boundary of the front and the back knitted fabric parts, is formed by twisting the stitches and winding a knitting yarn different from the knitting yarn forming the twisted stitch on the twisted stitch.
  • an outer appearance similar to the stitches formed by a sewing machine is obtained by the twisted stitch and the winding of the knitting yarn, and a knitted fabric excelling in design is obtained.
  • a knitted fabric is knitted with a four-bed flat knitting machine having a pair of front and back needle beds extending in a transverse direction and disposed opposite to each other in a cross section, the back needle bed is capable of being racked in the transverse direction so that stitches can be transferred between the front and back needle beds.
