Since the knitting yarn after cutting is pulled into the inside of the tubular fabric and absorbed, the yarn end can be kept invisible from the outside of the tubular fabric.
  • the knitting yarn of the floating section is retained by tucking into knitted loops forming the fabric, the knitting yarn need not be pulled in as in the case of knitting, and can be kept to a minimum length to be knitted into the fabric. Even when the yarn-fworked portion comes to the portion where the yarn-worked portion tucks, a load to pull in the knitting yarn can be reduced.
  • the knitting yarn of the floating section is retained to a fabric by passing the knitting yarn over the knitted loop that forms a fabric, the knitting yarn of the floating section can be retained without being knitted into the fabric.
  • retention of the knitting yarn of the floating section is conducted by passing the knitting yarn of the floating section alternately between on surface side and the other surface side after the knitting yarn near the folding-back position is wound. Since the wound yarn is cleared away after the knitting yarn is allowed to pass the fabric, the portion allowed to pass through the fabric can be easily removed after the floating yarn is cut.

  • a knitting yarn of a length enough to absorb errors of the position of the yarn-worked portion 2 should be pulled out as the floating yarn 4 which is not knitted into the fabric.
  • the floating yarn 4 is folded back at the leading end in such a manner that the floating yarn makes a round trip between the outward floating section 4a and the homeward floating section 4b.
  • tucking sections 5a and 5b are provided, respectively, in the fabric.
  • the floating yarn 4 is cut and removed in the subsequent process after knitting the fabric 1 having the yarn-worked portion.

  • the fabric 1 of a border pattern 3 as shown in Fig. 1 can be knitted by assigning each color of knitting yarn to each yarn feeder respectively, when the number of colors used is not large. In such event, if regions of the same color exist in distant locations, a floating yarn is generated in the longitudinal direction of the figure along the surface of the intermediate region in the knitting ends of the fabric 1. In an example disclosed in Patent Citation 2, this kind of floating yarn is generated in a plurality of places in the vertical direction of the figure. For cutting the floating yarn, scissors and other tools must be allowed to work on the direction perpendicular to the paper. Since the direction on which the tool is allowed to work is perpendicular to the direction in which the floating yarn to be treated is disposed, the floating yarn must be cut individually in multiple times. Furthermore, in the event that a long floating yarn is pulled out to the side end of the fabric in short section, the floating yarn must be cut under a condition in which the floating yarn hangs down from the side end, which still more decreased the cutting efficiency.

  • the leading end pulled out in such a manner as to contain the yarn-worked portion 2 is retained to the fabric by the retaining portion 6 and the floating yarn 4 is folded back, so that the knitting yarn is returned from the homeward floating section 4b to the inside of the tubular shaped fabric.
  • the knitting yarn of the homeward floating section 4b to be returned to the fabric is switched to a color-B knitting yarn at the yarn-worked portion 2, and a tucking section 5b is formed in a fabric knitted by the rear needle bed; then, the color-B region 3b of Step 3 continues to be knitted.

  • Step 4 the subsequent process to cut the floating yarn 4 takes place.
  • the transfer yarn 4 is cut at a position 7 closer to the tucking section 5 side than the yarn-worked portion 2. Since the section to be cut is exposed to the outside of the fabric along the surface of the tubular shaped fabric, cutting operation can be performed easily. Furthermore, if a plurality of cut positions 7 are disposed along the straight lines 7a, 7b, and 7c as shown in Fig. 1 , the plurality of positions can be cut efficiently. After cutting, as shown as Step 5, the leading end side of the floating yarn 4 containing the yarn-worked portion 2 is removed from the fabric.

  • Step 4-2 knitted loops are transferred from knitting needle “d” of BU to knitting needle “D” of FD and are put back in place.
  • Step 5 the knitting yarn is fed to the right direction and tucked to knitting needles "j", “I”, and “n” of BD.
  • the knitting yarn pulled out to the left in Step 4-1 forms the outward floating section 4a of the floating yarn 4.
  • the floating yarn 4 is pushed out to the outside of the needle bed gap on the front needle bed side, and can be exposed to the outside of the tubular shaped fabric.
  • the retention of the folded-back portion at the leading end of the floating yarn 4 is formed by winding the knitting yarn over a knitted loop only, and therefore, even when the knitting yarn is folded back at the yarn-worked portion 2, the knitting yarn is able to be retained without being tucked into the fabric.
  • Fig. 9 shows an example in which the treatment of the floating yarn 4 to be winded over a knitted loop retained at the knitting needle "D" of FD is conducted by transferring stitch later as in the case of Fig. 8 .
  • Step 3 transferring of a knitted loop to be retained on the knitting needle “D” of FD is not conducted but knitted loops to be retained to knitting needles "E” through “H” are transferred to knitting needles "e” through “h” of BU, respectively.
  • the knitted loop to be retained to the knitting needle “D” is transferred to the knitting needle "d" of BU in Step 4-2.
  • the knitting yarn is pushed out to the needle bed gap on the rear needle bed side by the knitted loop transferred to the knitting needle "d” of BU.
  • the floating yarn 4 enters the inside of the needle bed gap of the knitted loop to be retained to the knitting needle "d” of BU and is retained by winding over the knitted loop at the folded back portion.
  • the portion inside the needle bed gap when it is retained to the knitting needle "d” of BU before stitch transferring becomes the outside of the tubular shaped fabric and the portion pushed out to the outside the needle bed gap on the rear needle bed side becomes the inside of the tubular shaped fabric on the inside of the needle bed gap.
  • Fig. 10 partially shows schematic structure of fabrics 11, 21, and 31 having a yarn-work portion of another embodiment of the present invention with respect to the vicinity of the yarn-worked portion 2.
  • the same reference numbers are assigned to the elements which have the corresponding portions in Fig. 1 and Fig. 2 and redundant description will be omitted.
  • the fabric 11 having the yarn-worked portion shown in Fig. 10(a) is formed by passing the vicinity of the leading end at which the floating yarn 4 is folded back through the inside of the tubular shaped fabric at positions of a plurality of knitted loops 12, 13, and 14.
  • the floating yarn 4 is allowed to pass to the outside of the tubular shaped fabric between knitted loops 12, 13, and 14 or at positions of adjacent knitted loops.
  • the floating yarn 4 is passed alternately inside and outside the knit fabric in this way to form the retaining portion 16.
  • the point in which the outward floating section 4a and the homeward floating section 4b, both containing the yarn-worked portion 2, are brought outside the tubular shaped fabric is the same as that of the fabric 1 having the yarn-worked portion of Fig.
  • the retaining portion 16 by the section containing a plurality of knitted loops 12, 13, and 14 is not retained to the fabric at the leading end of the folded-back floating yarn 4.
  • the floating yarn 4 in a fabric 11 has the vicinity of the leading end merely allowed to alternately pass inside and outside the fabric at the section containing knitted loops 12, 13, and 14, and thus the floating yarn 4 can be easily removed after cutting. Since the floating yarn 4 is retained by a plurality of knitted loops 12, 13, and 14, the transfer yarn 4 is able to be securely retained until the transfer yarn 4 is cut.
  • a knit fabric 21 having a yarn-worked portion shown in Fig. 10(b) the majority of the floating yarn 4 is fixed to the inside of the tubular shaped fabric, and only the vicinity of the leading end to be folded back is allowed to pass a knitted loop 22 to the outside of the tubular shaped fabric to form the retaining portion 26.
  • the floating yarn 4 at the retaining portion 26 is retained by allowing the floating yarn 4 to pass alternately inside the tubular shaped fabric in the knitted loop 22, and outside the tubular shaped fabric in a knitted loop adjacent to the left of the knitted loop 22.
  • the floating yarn 4 is only pulled out to the outside of the tubular shaped fabric with raveling-stop provided in the tucking section 5, and retention to the vicinity of the leading end is omitted. Even if the floating yarn 4 is not retained, manual cutting is possible.
  • Fig. 11 through Fig. 14 schematically show a procedure for knitting the fabrics 11 and 21 having the yarn-worked portion as shown in Fig. 10(a) and Fig. 10(b) by a four-needle-bed knitting machine having two-tiered needle beds in front and rear.
  • Description on knitting in Fig. 11 through Fig. 14 is made under the conditions same as those for the description in Fig. 3 through Fig. 9 .
  • the number of knitting needles are described to be different, respectively, this is merely for the convenience for explanation, and in actual knitting of a fabric, a necessary quantity of knitting needles should be used.
  • Fig. 11 and Fig. 12 the fabric 11 having the yarn-worked portion shown in Fig. 10(a) is knitted.
  • Step 1 a course on the front needle bed side of a tubular shaped fabric is knitted by a color-A knitting yarn in the left direction.
  • Step 2 a course on the rear needle bed side is knitted by a color-A knitting yarn in the right direction.
  • Tubular knitting by this kind of round-knitting is repeated and in the final course shown as Step 2, no knitting is conducted in the final knitting needle "w" of BD.
  • the color-A region 3a of Fig. 10(a) is knitted except the final knitted loop.
  • Step 3 knitted loops retained on knitting needles "K” through “P” of FD corresponding to the section from which the floating yarn 4 of Fig. 10(a) is pulled out are moved to knitting needles "k” through “p” of BU by transferring.
  • knitted loops retained on knitting needles "E”, “G”, and “I” adjacent to knitting needles “F”, “H”, and “J” of FD corresponding to knitted loops 12, 13, and 14 are moved to knitting needles "e”, "g", and "i” of BU by stitch transferring.
  • next Step 4 the color-A knitting yarn is tucked to knitting needles "V” and “S” of FD and is pulled out from the vicinity of he position of the knitting needle “R” to the position of the knitting needle “D". Furthermore, the knitting yarn is hanged over the knitting needle “D” which is kept vacant and the outward floating section 4a of Fig. 10(a) is formed. In next Step 5-1, the knitting yarn hanged over the knitting needle “D” is folded back and tucked to knitting needles "s" and "v” of BD. The knitting yarn which forms the tacking section 5 of Fig.
  • Step 6 of Fig. 12 a knitted loop is formed on the final knitting needle "w" of BD by the color-B knitting yarn.
  • the yarn feeding direction is the left direction, reversal to the right direction in which the color-A knitting yarn is fed to knitting needles "a" through “v” in Step 2, and in Step 7-1, the yarn feeder is kicked back to form a twisted loop to the knitting needle "w", and the yarn feeder is brought on the right side of the knitted width.
  • this kind of treatment which is same as in Step 7 to Step 8 of Fig. 4 .
  • Step 7-2 the loop of the floating yarn 4 hanged over the knitting needle "D” of FD is removed.
  • the leading end of the floating yarn 4 is disengaged from a hook of the knitting needle “D” but it passes inside and outside the tubular shaped fabric alternately in the section of knitting needles "E” through “J", and this enables the floating yarn 4 to keep the retention condition.
  • Step 7-3 the knitted loop is returned from the knitting needle "d” of BU to the knitting needle "D” of FD. In such event, the folded-back portion of the leading end of the floating yarn 4 is pushed out to the outside of the needle bed gap by the knitted loop retained to the knitting needle "D" on the front needle bed side.
  • Step 8 with the knitting yarn switched to color-B, the course on the front needle bed side of the tubular shaped fabric is knitted in the left direction. Thereafter, repeating the same procedures when the knitting yarn is switched from color-B to color-A or any other colors can knit the tubular shaped fabric having the regions of the border pattern 3 as shown in Fig. 1 in multicolors.
  • the knit fabric 21 having the yarn-worked portion shown in Fig. 10(b) is knitted. From Step 1 to Step 2 of Fig. 13 , the fabric is knitted in the basically same manner as in the case of Step 1 to Step 2 of Fig. 11 . In Step 3 of Fig. 13 , knitted loops retained are moved from the knitting needle "E” adjacent to the knitting needle "F” of FD for retaining the knitted loop 22 of Fig. 10(b) and the knitting needle "D" which the floating yarn 4 is to be passed over, to knitting needles "e” and "d” by stitch transferring.
  • Step 4 the color-A knitting yarn is pulled out from the knitting needle "q"of BD which formed the final knitted loop in Step 2 to the position of the knitting needle "D" of FD, the yarn is hanged over the knitting needle "D" which is vacant, and the outward floating section 4a of Fig. 10(a) is formed.
  • Step 5-1 the knitting yarn with which a hanged-over loop was made on the knitting needle "D” is folded back and the homeward floating section 4b is formed.
  • the knitting yarn is switched from the color-A on the outward side to the color-B on the homeward side by the switching at the yarn-worked portion 2 of Fig. 10(b) .
  • Step 5-2 the knitted loop retained to the knitting needle "e” of BU is returned to the knitting needle "E” of FD.
  • the floating yarn 4 at the position of the knitting needle “E” is pushed out to the outside of the needle bed gap by the knitted loop retained to the knitting needle “E” on the front needle bed side.
  • Step 6 of Fig. 14 a knitted loop is formed by the color-B knitting yarn on the final knitting needle "r" of BD.
  • the yarn-feeding direction is the left direction, which is reversal to the right direction in which the color-A knitting yarn is fed to knitting needles "a" through “q” in Step 2.
  • Step 7-1 the yarn feeder is kicked back to form a twisted loop to the knitting needle "r”, and is brought on the right side of the knitted width. This kind of the twisted loop is formed in the same manner as is the case of Step 6 to Step 7-1 of Fig. 12 .
  • Step 7-2 to Step 7-3 same as Step 7-2 to Step 7-3 of Fig. 12 , a knitted loop of the floating yarn 4 hanged over the knitting needle "D" of FD is cleared away; the knitted loop is returned to the knitting needle "D” of FD from the knitting needle "d” of BU; and folded-back portion of the leading end of the floating yarn 4 is pushed out to the outside of the needle bed gap by the knitted loop on the front needle bed side.
  • Step 8 with the knitting yarn switched to color-B, the course on the front needle bed side of the tubular shaped fabric is knitted in the left direction.
  • repeating the same procedures when the knitting yarn is switched from color-B to color-A or any other colors can knit the tubular shaped fabric having the regions of the border pattern 3 as shown in Fig. 1 in multicolors.
  • Knitting of the fabric 31 having the yarn-worked portion as shown in Fig. 10(c) is conducted, for example, by carrying out the treatment, like as carried out at the knitting needle "D", at the knitting needle "J” instead of carrying out processing in knitting needles "E” through “J” of FD from Step 3 of Fig. 11 through Step 7-3 of Fig. 12 .
  • the folded-back portion at the leading end of the floating yarn 4 is temporarily hanged over the knitting needle "J” of FD but is cleared away from a hook of the knitting needle "J” and is pushed out to the outside of the needle bed gap on the front needle bed side. Since the floating yarn 4 pushed out to the outside of the needle bed gap is located on the outside of the tubular shaped fabric after completion of knitting, the directions can be aligned by manual operation and the portion containing the yarn-worked portion 2 can be easily cut.
  • the yarn-worded portion 2 may be formed not only by disposing an piecing device, or the like in the knitting yarn feeding route and working the knitting yarn in real time but also may be formed in advance by working the knitting yarn by prior batch treatment.
  • time restriction is alleviated.
  • the treatment can be satisfactorily carried out.
