MODE FOR CARRYING OUT THE INVENTION

Embodiments of a method for knitting a knitted fabric of the present invention will be hereinafter described based on the drawings. A knitting example using a two-bed flat knitting machine including a front needle bed (hereinafter referred to as FB) and a back needle bed (hereinafter referred to as BB) extending in a traverse direction and disposed opposite to each other in a front-back direction, and a yarn feeder that feeds a knitting yarn, the BB being rackable in the traverse direction and stitches being transferable, will be described. The flat knitting machine to be used is not, of course, limited to the two-bed flat knitting machine, and may be, for example, a four-bed flat knitting machine.

First Embodiment

<<Overall Configuration>>

In the first embodiment, a method for knitting a knitted fabric of the present invention will be described using a shoe upper (knitted fabric) 100 shown in FIG. 1 by way of example. The shoe upper 100 is configured by an instep cover 110 that covers a portion on an instep side of a foot and a sole cover 120 that covers a sole, and is knitted in a seamless manner with the flat knitting machine. A decoration pattern 111 in which a plurality of box-shaped decoration units 2 is connected in a chain form is formed in the instep cover 110. The decoration pattern 111 appears as if formed by sewing, but is formed by knitting. For the sake of convenience, a portion on an upper side of the decoration pattern 111 of the instep cover 110 is referred to as an instep portion 112, and a portion on a lower side is referred to as a side portion 113.

The box-shaped decoration unit 2 is configured by a lower edge 2D, a left edge 2L, a right edge 2R, and an upper edge 2U. The lower edge 2D and the upper edge 2U are configured with a cross-over yarn extending in a knitting width direction of a base knitted fabric portion 1 (instep cover 110). The left edge 2L and the right edge 2R are configured with stitches stretched in a wale direction (direction intersecting the knitting width direction) of the base knitted fabric portion 1. The stitch configuring the left edge 2L is connected to a left end of the cross-over yarn configuring the lower edge 2D. The stitch configuring the right edge 2R appears as if not connected to a right end of the lower edge 2D. This is because one part of the right end of the lower edge 2D is arranged on a back side of the base knitted fabric portion 1 on purpose so that the decoration unit 2 has a sewn appearance, and actually, the stitch configuring the right edge 2R is connected to the cross-over yarn configuring the lower edge 2D on the back side of the base knitted fabric portion 1. In the present example, the right edge 2R of the decoration unit 2 on the left side also serves as the left edge 2L of the decoration unit 2 on the right side. The decoration unit 2 including these sides 2D, 2L, 2R, and 2U is knitted in a seamless manner using the flat knitting machine. Hereinafter, the method for knitting the knitted fabric of knitting the decoration unit 2 will be described.

<<Method for Knitting Shoe Upper>>

Before describing the knitting procedure of the decoration unit 2, an overall knitting procedure of the shoe upper 100 will be described first. The shoe upper 100 can be knitted, for example, according to a procedure shown in FIG. 2. In the procedure shown in FIG. 2, the shoe upper 100 is knitted sideways on the needle bed. In FIG. 2, only the right side portion is illustrated for a portion where the decoration pattern 111 is formed, the side portion 113, and the sole cover 120, and the left side portion thereof is arranged on the far side of the right side portion.

In FIG. 2, a set up section 100s is first formed on the FB and the BB. Following the set up section 100s, the instep portion 112 of the instep cover 110 is knitted using the FB (or BB). Next, after the portion where the decoration pattern 111 is formed is knitted using the FB and the BB, the side portion 113 of the instep cover 110 is knitted through the tubular knitting and the reciprocate knitting using the FB and the BB. The reciprocate knitting is carried out separately for the FB and the BB to knit the right side portion and the left side portion of the sole cover 120, and lastly, the right side portion and the left side portion are joined by knitting.

<<Knitting of Decoration Pattern as if Sewn>>

The portion where the decoration pattern 111 is formed shown in FIG. 2 can be knitted according to the knitting process diagrams shown in FIGS. 3 to 5. “S+number” of a left column of FIGS. 3 to 5 indicates a number of a knitting process, and a formed state of the stitches in the FB and the BB is shown in a right column. The portion where knitting is actually carried out in each process is shown with a thick line. Upper case alphabets in the drawings indicate the positions of knitting needles. The stitches of a base knitted fabric portion 1F are indicated with a diamond shaped mark, the stitches of a base knitted fabric portion 1B are indicated with a pentagon shaped mark, and the stitches knitted with a decoration knitting yarn Y8 different from a base knitting yarn Y7 for knitting the base knitted fabric portions 1F, 1B are indicated with a circular mark. The double mark indicates a double stitch.

In S0, a state in which the stitches of the base knitted fabric portion 1F are held on the knitting needles B to P of the FB, and the stitches of the base knitted fabric portion 1B are held on the knitting needles B to P of the BB is shown. The base knitted fabric portions 1F, 1B are knitted with the base knitting yarn Y7. Wool yarn, elastic yarn, thermally fusible yarn, or the like can be used for the base knitting yarn Y7. When forming the decoration pattern 111 in the shoe upper, the base knitting yarn Y7 is preferably a thermally fusible yarn. An empty needle is not formed within a knitting width of the base knitted fabric portions 1F, 1B and the base knitted fabric portions 1F, 1B including closely formed stitches are obtained. The knitting of the decoration unit 111 (see FIGS. 1 and 2) is carried out from such state.

In S1, a part of the base knitted fabric portions 1F, 1B is moved in the knitting width direction, and an empty needle is formed within the knitting width of the base knitted fabric portions 1F, 1B. The empty needle formed in the BB (FB) is provided to temporarily move the stitches of the base knitted fabric portion 1F (1B) when forming the decoration unit 2 in the base knitted fabric portion 1F (1B) (see next S2 for operation of temporarily moving the base knitted fabric portion 1F). The position of forming the empty needle is preferably selected such that the moving distance of the stitch becomes small when temporarily moving the base knitted fabric portion 1F (1B) to the BB (FB). In the present example, the stitches held on the knitting needles E, G, K, M of the FB and the knitting needles E, G, K, M of the BB are overlapped with the stitches on the immediate left of the plane of drawing so that the knitting needles E, G, K, M become the empty needles. The double stitches formed in S1 are indicated with a single mark instead of a double mark after S2.

In S2, the stitches of the base knitted fabric portion 1F held on the knitting needles B, F, H, L, N of the FB are transferred to the knitting needles A, E, G, K, M of the BB. According to such transfer, the stitches of the base knitted fabric portion 1F remain on the knitting needles C, D, I, J, O, P of the FB (corresponding to process α). Some of the stitches remaining on the FB are a left side starting stitch 11 that becomes a starting point for forming the left edge 2L of the decoration unit 2 and a right side starting stitch 19 that becomes a starting point for forming the right edge 2R of the decoration unit 2 shown in a circled enlarged view of FIG. 1. This is specifically described as below.

• • The stitch of the knitting needle D of the FB is the left side starting stitch 11 for forming the left edge 2L of the decoration unit 2 on the left side.
  • The stitch of the knitting needle J of the FB is the right side starting stitch 19 for forming the right edge 2R of the decoration unit 2 on the left side, and the left side starting stitch 11 for forming the left edge 2L of the decoration unit 2 on the right side.
  • The stitch of the knitting needle P of the FB is the right side starting stitch 19 for forming the right edge 2R of the decoration unit 2 on the right side.

In S3, the decoration knitting yarn Y8, which is a knitting yarn different from the base knitting yarn Y7, is fed from the yarn feeder 8 to form a pickup stitch 25 on the knitting needles B, F, H, L, N of the FB, and form a stitch following the starting stitches 11, 19 of the knitting needles D, J, P of the FB (corresponding to process β). The stitch formed on the knitting needle D of the FB is a left edge stitch 21 that becomes the left edge 2L of the decoration unit 2 on the left side. The stitch formed on the knitting needle J of the FB is a right edge stitch 29 that becomes the right edge 2R of the decoration unit 2 on the left side, and is also the left edge stitch 21 that becomes the left edge 2L of the decoration unit 2 on the right side. The stitch formed on the knitting needle P of the FB is the right edge stitch 29 that becomes the right edge 2R of the decoration unit 2 on the right side. The decoration knitting yarn Y8 is a knitting yarn that differs from the base knitting yarn Y7 in material, texture, thickness, or color. In particular, the decoration unit 2 can be formed to stand out by differing the color of the decoration knitting yarn Y8 from the color of the base knitting yarn Y7.

Either the left edge stitch 21 or the right edge stitch 29 may be formed first. Which stitch 21, 29 to be formed first depends on the moving direction of the yarn feeder 8.

Furthermore, the position of forming the pickup stitch 25 is not particularly limited. In the case of the present example, the pickup stitch 25 is formed on the FB since the empty needle is not provided on the BB, but the pickup stitch 25 may be formed on an upper back needle bed when, for example, the four-bed flat knitting machine is used. As the pickup stitch 25 is removed from the needle bed in the next S4, the pickup stitch may be formed on the knitting needle of any needle bed.

In S4, the pickup stitch 25 formed in S3 is removed from the FB (corresponding to process γ). As a result, the lower edge 2D configured with the decoration knitting yarn Y8 that traverses the front side of the stitches of the base knitted fabric portion 1F (stitches of the knitting needles A, E, G, K, M of the BB) transferred to the BB in S2 is formed. Since the yarn length between the left edge stitch 21 and the right edge stitch 29 becomes long by the amount of the pickup stitch 25 removed from the FB, the stitches 21, 29 can be enlarged. In S4, in addition to removing the pickup stitch 25 from the FB, the knitting needles D, J, P of the FB on which the left edge stitch 11 and the right edge stitch 19 are held may be withdrawn from a needle gap to enlarge the left edge stitch 21 and the right edge stitch 29.

In S5, the stitches of the base knitted fabric portion 1F temporarily moved to the knitting needles A, E, G, K, M of the BB in S2 are returned to the knitting needles B, F, H, L, N of the FB. After S5, the knitting similar to S2 to S5 is also carried out with respect to the base knitted fabric portion 1B. The held state of the stitches when the knitting with respect to the base knitted fabric portion 1B is completed and the arrangement state of the decoration knitting yarn Y8 are shown in S6.

In S7 of FIG. 4, the arrangement of the stitches in the FB is changed. Specifically, the stitches of the base knitted fabric portion 1F held on the knitting needles C, I, O of the FB are transferred to the knitting needles D, J, P of the FB, and the left edge stitch 21 and the right edge stitch 29 held on the knitting needles D, J, P of the FB are transferred to the knitting needles E, K, Q of the FB. The arrangement of the stitches is changed here to make the interval of each stitch of the base knitted fabric portion 1F equal, so that the size of each stitch of the base knitted fabric portion 1F is made the same when knitting the base knitted fabric portion 1F in the next S8.

In S8, the yarn feeder 7 is moved in one direction to form a new stitch on the stitches held on the knitting needles B, D, F, H, J, L, N, P of the FB, and form the pickup stitch on the knitting needles E, G, K, M of the BB (corresponding to process δ₁). According to S8, the base knitted fabric portion 1F is branched to a base front part 10F knitted with the FB and a base back part 10B knitted with the BB.

In S9, a new stitch is knitted on the stitch of the base back part 10B held on the BB, and in S10, a new stitch is knitted on the stitch of the base front part 10F held on the FB. S9 and S10 are repeated as necessary (corresponding to process δ₂). The lengths of the left edge 2L and the right edge 2R of the decoration unit 2 are determined by the number of repetitions. A tube shape in which the cross-section of the portion where the decoration unit 2 is formed in the base knitted fabric portion 1F is a substantially circular shape is obtained by repeating S9 and S10 by the same number of times. A tube shape in which the cross-section is a substantially D-shape is obtained by making the number of times to carry out S10 greater than the number of times to carry out S9 or by repeating only S10 without carrying out S9. In such a case, a side to be touched by the wearer of the base knitted fabric portion 1 can be formed to a flat shape.

When the base knitted fabric portion 1B is formed to a tube shape, similar to the base knitted fabric portion 1F, a hole at an end of the base knitted fabric portion 1F and a hole at an end of the base knitted fabric portion 1B may be connected. When connecting the holes, the pickup stitch may be formed on the outer side of the knitting width of the base knitted fabric portion 1F when increasing the knitting course of the base knitted fabric portion 1F, and the pickup stitch may be interweaved in the base knitted fabric portion 1B when knitting the base knitted fabric portion 1B.

In S11, the base back part 10B held on the knitting needles E, G, K, M of the BB is overlapped with the base front part 10F held on the knitting needles D, F, J, L of the FB. S11 is a process carried out to connect the base front part 10F and the base back part 10B, but the parts 10F, 10B are not yet connected at this point of time.

After S11, knitting similar to S8 to S11 is also carried out with respect to the base knitted fabric portion 1B. The held state of the stitches when the knitting with respect to the base knitted fabric portion 1B is completed is shown in S12.

In S13 of FIG. 5, the base knitted fabric portions 1F, 1B are knitted for one course (corresponding to process δ₃). According to S13, the base front part 10F and the base back part 10B of the base knitted fabric portion 1F (1B) are connected.

In S14, the stitches of the base knitted fabric portion 1F held on the knitting needles B, D, H, J, N, P of the FB are transferred to the knitting needles C, E, I, K, O, Q of the BB. According to such transfer, the stitches of the base knitted fabric portion 1F remain on the knitting needles F, L of the FB (process ζ). The stitch of the knitting needle F of the FB is a left fixing stitch 13 for fixing the left end of the upper edge 2U in the decoration unit 2 on the left side shown in a circled enlarged view of FIG. 1. The stitch of the stitch L of the FB is a right fixing stitch 17 for fixing a right end of the upper edge 2U in the decoration unit 2 on the left side, and is also the left fixing stitch 13 for fixing the left end of the upper edge 2U in the decoration unit 2 on the right side. For the sake of convenience of the plane of drawing, the right fixing stitch 17 for the decoration unit 2 on the right side is not shown in S15.

In S15, the yarn feeder 8 is moved in one direction to carry out tuck on the stitches 13, 17 of the knitting needles F, L of the FB, and to carry out miss on other portions (corresponding to process η). As a result, the upper edge 2U configured with the decoration knitting yarn Y8 that traverses the front side of the stitches of the base knitted fabric portion 1F (stitches of the knitting needles C, E, I, K, O, Q of the BB) transferred to the BB in S14 is formed.

In S16, the stitches of the base knitted fabric portion 1F temporarily moved to the knitting needles C, E, I, K, O, Q of the BB in S14 are returned to the knitting needles B, D, H, J, N, P of the FB. After S16, knitting similar to S14 to S16 is also carried out with respect to the base knitted fabric portion 1B. The held state of the stitches when the knitting with respect to the base knitted fabric portion 1B is completed and the arrangement state of the decoration knitting yarn Y8 are shown in S17.

In S18, a new stitch following a wale direction of the stitches of the base knitted fabric portions 1F, 1B, the left edge stitch 21, and the right edge stitch 29 are knitted and a twisted stitch shown with an outlined arrow is knitted on the empty needle (corresponding to process ε). According to S18, the left edge stitch 21 and the right edge stitch 29 are connected to the base knitted fabric portions 1F, 1B, and the left edge 2L and the right edge 2R of the decoration unit 2 are formed. The twisted stitch formed in S18 is provided to return the number of stitches lined in the knitting width direction reduced in S1 of FIG. 3 back to the original number.

According to the knitting process described above, the decoration pattern 111 shown in FIG. 1 can be formed in the shoe upper 100 in a seamless manner. The knitted fabric including such decoration pattern 111 is a novel knitted fabric which has not existed before.

Second Embodiment

A variety of decoration units 2 can be knitted by applying the method for knitting the knitted fabric described in the first embodiment. One example of such decoration unit is illustrated in FIGS. 6A to 6D. In FIG. 6, the left edge 2L and the right edge 2R configured by stitches are shown with a thick line for the sake of convenience of explanation.

FIG. 6A shows the decoration unit 2 configured by the lower edge 2D, the left edge 2L, and the right edge 2R. When knitting such decoration unit 2, the knitting of S1 of FIGS. 3 to S13 of FIG. 5 is carried out, and thereafter, the knitting corresponding to S18 is carried out without carrying out the knitting corresponding to S14 to S16 with respect to the base knitted fabric portions 1F, 1B.

FIG. 6B shows the decoration unit 2 in which the left edge 2L and the right edge 2R are inclined. When knitting such decoration unit 2, the knitting corresponding to S18 is carried out after moving the left edge stitch 21 and the right edge stitch 29 to different positions in the knitting width direction after S17 of FIG. 5. In FIG. 6B, the lower edge 2D and the right edge 2R are connected, but this can be achieved by leaving only the starting stitches 11, 19 on the FB in S2 of FIG. 3.

FIG. 6C shows the decoration unit 2 formed to a dotted line form. When knitting such decoration unit 2, the lower edge 2D of a dotted line form and the short left edge 2L and right edge 2R are first knitted. In S2 of FIG. 3, the lower edge 2D can be knitted by allocating a plurality of stitches between the left side starting stitch 11 and the right side starting stitch 19 to the FB and the BB, in S2 of FIG. 3.

After fixing the left edge 2L and the right edge 2R to the base knitted fabric portion, the base knitted fabric portion and an auxiliary edge 2Lh (auxiliary when forming the base knitted fabric portion 1B to a tube shape 2Rh) following the left edge 2L (right edge 2R) is knitted. The auxiliary edges 2Lh, 2Rh can be formed by knitting stitches in the base knitted fabric portion with the decoration knitting yarn. The upper edge 2U can be knitted by allocating a plurality of stitches between the left fixing stitch 13 and the right fixing stitch 17 to the FB and the BB, in S14 of FIG. 5.

FIG. 6D shows the decoration unit 2 continuing in the wale direction of the base knitted fabric portion. In this example, the lower edge 2D of the decoration unit 2 on the upper course also serves as the upper edge 2U of the decoration unit 2 on the lower course. In such a case, the lower edge 2D, the left edge 2L, and the right edge 2R of the decoration unit 2 on the upper course are knitted after the lower edge 2D, the left edge 2L, and the right edge 2R of the decoration unit 2 on the lower course are knitted. The upper edge 2U of the decoration unit 2 on the upper course is obtained through the knitting similar to the knitting of S14 to S16 of FIG. 5. Such knitting can also be carried out while shifting the decoration unit 2 on the lower course and the decoration unit 2 on the upper course. Accordingly, a decoration of a brick wall like pattern can be formed.

Although not shown, the decoration unit in which the lower edge, the left edge, and the right edge form a triangular shape can be formed. In such a case, the left edge stitch 21 and the right edge stitch 29 are overlapped when carrying out S18 of FIG. 5.

A plurality of decoration units can be formed at positions spaced apart in the knitting width direction. The decoration unit on the left side and the decoration unit on the right side can be knitted continuously all at once. For example, when moving the yarn feeder for feeding the decoration knitting yarn toward the right side, the left edge stitch, the cross-over yarn of the lower edge, and the right edge stitch of the decoration unit on the left side are formed, and thereafter, the decoration knitting yarn is passed to the back side of the base knitted fabric portion, and then the left edge stitch, the cross-over yarn of the lower edge, and the right edge stitch of the decoration unit on the right side are formed.

<Others>

The decoration unit 2 described in the first and second embodiments can also be applied to a knitted fabric other than the shoe upper 100. For example, the decoration unit 2 can be applied to knitwear, knit pants, small knitted articles such as a handkerchief, and furthermore, a knitted cover, and the like, thus enhancing the designability thereof.
