Description

  The present invention relates to knitting a tubular knitted fabric for knitting a tubular knitted fabric with a flat knitting machine including an integrated tubular portion and a plurality of independent branched tubular portions that are continuous in the wale direction of the integrated tubular portion. The present invention relates to a method and a tubular knitted fabric knitted using the knitting method.

  Most of the knitwear has a configuration including a plurality of branch tube portions independent from each other and an integrated tube portion formed by collecting these branch tube portions. For example, an outerwear such as a sweater is a tubular knitted fabric formed by gathering two tubular sleeves and a tubular body, and an underwear such as pants is gathered by two legs at the crotch. This is a tubular knitted fabric connected to one body part. Gloves and socks with finger bags are also tubular knitted fabrics made up of a plurality of tubular finger bags.

  When the tubular knitted fabric is knitted without sewing with a flat knitting machine having at least a pair of front and back needle beds, a plurality of branch tube portions are individually knitted, and the branch tube portions are joined together and then integrated tube portions. It is common to organize. For example, in Patent Document 1, when a knit pant is knitted using a flat knitting machine, a cylindrical left foot and a right foot are knitted, and the left foot and the right foot are joined, and then the trunk is tubular. Is formed. At the time of joining, some stitch groups arranged at the end of the left foot part and some stitch groups arranged at the end of the right foot part are overlapped so that the knit pants have a three-dimensional shape that conforms to the shape of the human body. To form a ridge in the thickness direction of the knit pants.

Japanese Patent No. 3887408

  However, in the knitting method of Patent Document 1, overlapping stitches for overlapping a plurality of stitches of each branch tube portion to be joined are continuously formed at the heel forming position. The double stitches may stand out when the vicinity of the double stitches is plain, and may restrain the comfort of the tubular knitted fabric because it restrains the elongation of the tubular knitted fabric.

  The present invention has been made in view of the above circumstances, and in a tubular knitted fabric in which a heel is formed at the crotch position of a plurality of branch cylinder portions branched from the integrated cylinder portion, a double stitch is formed at the position of the heel. An object is to provide a knitting method of a tubular knitted fabric that is not formed, and a tubular knitted fabric knitted by applying the knitting method.

The knitting method of the tubular knitted fabric of the present invention is integrated using a flat knitting machine having at least a pair of front and back needle beds and capable of transferring stitches locked to the knitting needles of the needle beds to another knitting needle. A knitting method of a tubular knitted fabric for knitting a tubular knitted fabric comprising a tubular portion and a plurality of independent branched tubular portions formed continuously in the wale direction of the integrated tubular portion, The following steps α to ε are provided.
(Step α) Knit the integrated tube portion.
(Step β) Within the knitting width of the integrated tube portion, the knitting needles are locked to the knitting needles by alternately supplying the knitting yarns to the knitting needles of the front and back needle beds where the stitches of the integrated tube portion are not locked. A plurality of locking eyes are formed.
(Step γ) Of the engagement stitches formed on the knitting needle in Step β, the engagement portion engaged with the knitting needle of one needle bed is transferred to the knitting needle of the other needle bed, and the transfer mechanism is transferred. Knitting is performed using a part of the knitting needles within the knitting width of the integrated tube portion including the knitting needles that lock the stop, and one of the branched tube portions following the integrated tube portion is knitted.
(Step δ) Among the stitches knitted in step γ, the stitches locked to the knitting needles of the other needle bed and the stitches in the formation range of the locking stitches formed in step β are knitting needles of one needle bed Move to.
(Step ε) Of the locking stitches formed on the knitting needles in Step β, the locking eyes locked to the knitting needles of the other needle bed that were not transferred in Step γ are applied to the knitting needles of one needle bed. After the transfer, knitting is performed using a part of the knitting needles within the knitting width of the integrated tube portion including the knitting needles that lock the transferred lock, and adjacent to the branch tube portion created in step γ. Create another branch tube.

  Note that there may be a plurality of integrated cylindrical portions in one cylindrical knitted fabric. For example, a five-finger sock described in an embodiment described later is a typical example of a tubular knitted fabric having a plurality of integrated tubular portions.

  As a form of the knitting method of the tubular knitted fabric of the present invention, a process of increasing the number of knitting courses of one branch cylinder portion knitted in step γ and the number of knitting courses of another branch tube portion knitted in step ε Thus, it is preferable to knitting each branch cylinder portion alternately by 1 to 5 courses. When knitting each branch cylinder part, the stitches of the other branch cylinder part overlapping the knitting area of the branch cylinder part are placed on either the front or back needle bed so as not to interfere with the knitting of the branch cylinder part. Keep it biased and locked.

  As a form of the knitting method of the tubular knitted fabric of the present invention, a process of increasing the number of knitting courses of one branch cylinder portion knitted in step γ and the number of knitting courses of another branch tube portion knitted in step ε Thus, it is preferable that the positions at which the stitches of both branch cylinder portions on the front and back needle beds are locked are separated in the knitting width direction so that the knitting regions of both branch cylinder portions do not overlap in the knitting width direction. In that case, only one of the branch tube portions may be moved away from the other branch tube portion by transfer, or both branch tube portions may be moved away from each other by transfer.

  Further, the tubular knitted fabric of the present invention is knitted using a flat knitting machine having at least a pair of front and back needle beds and capable of transferring the stitches locked to the knitting needles of the needle beds to another knitting needle. It is a tubular knitted fabric, and includes an integrated tube portion and a plurality of independent branch tube portions that are formed continuously in the wale direction of the integrated tube portion. This tubular knitted fabric of the present invention is configured by stacking knitting courses from the integrated tube portion side toward the branch tube portion side. The cylindrical knitted fabric of the present invention is a crotch position where two adjacent branch cylinder portions branch, and a part of the stitch group in the first knitting course of one branch cylinder portion and the number of the second branch cylinder portion. It is characterized in that a joining knitting yarn is provided, which is alternately entangled with a part of stitch groups in one knitting course and joins both stitch groups.

  According to the knitting method of the tubular knitted fabric of the present invention, the tubular knitted fabric of the present invention can be knitted with a plurality of branched tubular portions formed continuously in the wale direction on the integrated tubular portion, and adjacent to the tubular knitted fabric. A crease is formed at the position of the crotch of the branching cylinder portion, and no overlap is formed at the crease portion. Therefore, the appearance of the crotch position of the adjacent branch cylinder part is good, and the stretchability of the tubular knitted fabric is not impaired at the crotch.

  Further, in the process of increasing the number of knitting courses of two adjacent branch cylinder parts, each branch cylinder part is knitted alternately by 1 to 5 courses, so that the knitting of both branch cylinder parts can be made smooth. . Temporarily, if only the knitting course of one adjacent branch cylinder part is knitted intensively, the other branch cylinder part locked by the knitting needle and not knitted will cause the one branch cylinder part to be knitted. There is a risk of disruption and organization. Such a problem hardly occurs if the number of courses is about 5 for each branch tube portion.

  Furthermore, in the process of increasing the number of knitting courses of two adjacent branch tube portions, when knitting one of both branch tube portions by preventing the knitting areas of both branch tube portions from overlapping in the knitting width direction. Therefore, it is not necessary to bias the stitches of the other branch cylinder part to either one of the front and back needle beds and lock them. As a result, both branch cylinder parts can be knitted in parallel at the same time, and the knitting efficiency of the tubular knitted fabric of the present invention is greatly improved.

It is the schematic of the knit pants shown in embodiment. It is a knitting process figure of the knit pants shown in the embodiment. (A)-(D) are schematic diagrams which show the knitted state of the knit pants in a knitting process with time. It is a partial loop figure in the crotch part of the knit pants shown in embodiment.

(A) is the schematic of the five-finger socks shown in the embodiment, and (B) to (E) are schematic diagrams showing the knitted state of the socks in the knitting process over time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The knitting described in the present embodiment is an example of knitting using a two-bed flat knitting machine having a pair of front and back needle beds extending in the left-right direction and facing each other in the front-rear direction. The flat knitting machine used may be a four-bed flat knitting machine.

  In this embodiment, an example in which the knitting method of the tubular knitted fabric of the present invention is applied to the knitting of the general knit pants 1 shown in FIG. The knitted pants 1 are a cylindrical torso (integrated tube portion) 2 that covers the waist and buttocks of the human body, and a cylindrical left foot portion (branched tube portion) formed at a position below the crotch portion 3 indicated by a one-dot chain line. 4 and a right foot part (branch tube part) 5. In addition, the knit pant 1 is formed with a heel extending in the thickness direction of the knit pant 1 at the position of the crotch part 3 of both feet 4 and 5, and is three-dimensionally formed so as to follow the shape of the human body. When the knitted pants 1 are knitted, generally, the legs 4 and 5 are knitted independently and both legs are formed so that a heel is formed at the position of the crotch 3 of the legs 4 and 5. The parts 2 and 5 are joined to form the body 2 which is one large cylindrical knitted fabric. On the other hand, in this embodiment, when the knitting is started from the upper end of the trunk portion 2 and the knitting of the trunk portion 2 is finished up to the position of the crotch portion 3, the two independent foot portions 4, which follow the trunk portion 2, are provided. 5 is knitted according to the knitting process shown in FIG.

  FIG. 2 is a knitting process diagram when knitting the legs 4 and 5 from the vicinity of the crotch 3 in the trunk 2 of the knit pants 1. In FIG. 2, “S + number” in the left column is the number of the knitting process, the drawing in the middle column is the stitching state of the stitches or hooks in the needle bed, and the up and down arrows in the right column are the stitches between the opposing needle beds. The left and right arrows indicate the knitting direction. In FIG. 2, FB is the front needle bed, BB is the rear needle bed, ▽ is the yarn feeder, alphabets A to Z, A 'and B' are the positions of the knitting needles on the needle bed, ○ is the stitch, and V is the hook or tack Showing eyes. On the other hand, FIG. 3 is a schematic diagram showing a knitted state of the knit pants 1 at the main points of the knitting process shown in FIG.

  S1 in FIG. 2 shows a state in which the final course of the body portion 2 is knitted by circular knitting using knitting needles every two stitches. This state corresponds to a state in which the body part 2 is knitted to the position of the crotch part 3 of the knit pant 1 which is one tubular knitted fabric as shown in FIG. 3A (see also FIG. 1). From this state of S1, knitting of the foot portions 4 and 5 is started according to the knitting process shown below.

  In S2, a new stitch is formed on the knitting needles A and D of the FB to which the stitches of the body 2 are locked and a tack is formed on the knitting needle G of the FB while moving the yarn feeder 8 in the right direction on the paper surface. The knitting yarns are alternately fed back and forth with respect to the knitting needles of the front and rear needle beds (the knitting needles K, N, Q, and T of the FB and the knitting needles I, L, O, and R of the BB) where the second stitch is not locked. Thus, a hook (locking eye) is formed. Finally, a tuck stitch is formed on the knitting needle V of the BB to which the stitch of the trunk portion 2 is locked (see also FIG. 3B). The hooks formed alternately on the FB and the BB in S2 serve as a foothold for knitting the foot portions 4 and 5 in the subsequent process. The knitting yarn fed from the yarn feeder 8 and zigzag between the FB and the BB to form these hooks is one of the foot portions 4 and 5 in the finished knit pants 1 as will be described later. It becomes the joining knitting yarn 6 which joins parts.

  Since the stitches formed in S2 are transferred in a subsequent process, a stitch is formed in advance with a thread before S2, and a new stitch (locking stitch) following the stitch is formed in S2. It is preferable to form. This is because the stitches can be transferred more easily than the hooks. In that case, when the knitting of the knit pants 1 is finished, the thread is removed from the knit pants 1.

  In S3, the stitches formed on the knitting needles R, O, L, and I of the BB in S2 are transferred to the knitting needles R, O, L, and I of the FB facing each other. In S4, the yarn feeder 8 is moved to the left in the drawing, then moved to the right in the drawing, and the left foot 4 is knitted by the circular knitting that is further moved to the left in the drawing. In the circular knitting, the knitting needles (knitting needles I, L, O, R of the FB) to which the transferred hooks are locked are located on the left side of the paper (one end side in the knitting width direction) from these knitting needles. Knitting needles (knitting needles A, D, G) of the FB, and knitting needles (knitting needles A, D, G, BB of the BB) which are located substantially opposite to the knitting needles of the FB and lock the stitches of the body 2 J, M, P, S) and new stitches are formed.

  In S5, as preparation for knitting the right foot portion 5, after transferring to the knitting needles I, L, O, R of the BB facing the stitches locked to the knitting needles I, L, O, R of the FB formed in S4, Transfer to the knitting needles K, N, Q, T of the BB facing the hooks locked to the knitting needles K, N, Q, T of the FB formed in S2. In S6, the right foot portion 5 is knitted by circular knitting in which a new yarn feeder 9 is introduced from the right side of the drawing and reciprocated (see also FIG. 3C). In the circular knitting, the knitting needles (BB knitting needles K, N, Q, T) to which the hooks transferred to the BB are locked are located on the right side (the other side in the knitting width direction) of the knitting needles. The knitting needles (BB knitting needles V, Y, B ′) for locking the stitches of the portion 2 and the knitting needles (FB knitting needles J, FB) which are located substantially opposite to the BB knitting needles and lock the stitches of the body portion 2 M, P, S, V, Y, B ′) and new stitches are formed.

  In S5, the FB stitch formed in S4 is transferred to the opposite BB. If there is a knitting yarn that crosses between the front and back needle beds in the knitting region of the right foot 5 knitted in S6, this knitting This is because the yarn is entangled with the knitting yarn constituting the right foot 5.

  In S7, a state is shown in which transfer is made to the knitting needles K, N, Q, and T of the FB facing the stitches locked to the knitting needles K, N, Q, and T of the BB formed in S6. As shown in S <b> 7, the left foot portion 4 and the right foot portion 5 are knitted completely independently from the body portion 2.

  Thereafter, the number of knitting courses of the feet 4 and 5 may be increased to complete the feet 4 and 5 (see also FIG. 3D). At that time, similarly to the knitting shown in S3 to S5, when one of the foot portions 4 and 5 is knitted, the knitting yarn knitting the foot portion and the knitting yarn of the other foot portion are intertwined. Do not. For example, when the right foot portion 5 is knitted, the stitch that overlaps the knitting area of the right foot portion 5 among the stitches of the left foot portion 4 is brought close to BB, and the knitting yarn constituting the right foot portion 5 and the left foot portion 4 are configured. Avoid entanglement with the knitting yarn. The BB that keeps the stitches of the left foot part 4 is a needle bed in which the left foot part 4 is approached in S5 when the right foot part 5 is created in S6. Here, the left foot portion 4 and the right foot portion 5 are preferably knitted alternately by 1 to 5 courses.

  Further, in the process of knitting the feet 4 and 5, the positions where the stitches of the feet 4 and 5 are locked are arranged on the left and right sides of the page so that the knitting areas of the feet 4 and 5 do not overlap in the knitting width direction. It is preferable to gradually move away in the direction. Here, if the knitted pants 1 in which the diameters of the foot portions 4 and 5 are gradually reduced are knitted, the knitting widths of the foot portions 4 and 5 are gradually reduced to thereby knitting the foot portions 4 and 5. It is also possible to prevent the areas from overlapping.

  In the knit pants 1 obtained through the knitting process described above, as shown in FIG. 4 which is a partially enlarged loop diagram of the crotch portion 3 of the knit pants 1, some stitches in the first knitting course of the left foot portion 4 The two legs 4 and 5 of the knitted pants 1 are branched by the joining knitting yarn 6 which is entangled so as to alternately sew the group and a part of the stitch group in the first knitting course of the right foot part 5 and joins both the stitch groups. It can be seen that the legs 4 and 5 are joined with the heel formed at the crotch position. Since this joint knitting yarn 6 connects both the foot portions 4 and 5 so that a crease can be formed at the position of the crotch without forming a double stitch, the joint portion is hardly noticeable in the knit pants 1. The stretchability of the crotch position is not impaired by the joint. Further, since both ends of the joined knitting yarn 6 are connected to the body portion 2 and the left foot portion 4 (see S2 to S4 in FIG. 2), the joined knitting yarn is not detached from the knit pants 1. 6 can firmly hold the joints of the feet 4 and 5.

  In addition, embodiment of this invention is not necessarily limited to the knitting of the knit pants mentioned above, It can change suitably in the range which does not deviate from the summary of this invention. For example, the knitting method of the tubular knitted fabric of the present invention may be applied to knitting sweaters, socks and gloves. As a representative, the knitting of the sweater and the knitting of the socks will be briefly described with reference to FIGS. 5 and 6, respectively.

  If the sweater 10 shown in FIG. 5A is knitted, a tubular knitted fabric (integrated tube portion) 101 corresponding to the neck hole of the sweater 10 to the armpit indicated by the alternate long and short dash line is necked using the yarn feeder 8. Knit from the hole side (see FIG. 5B). Next, hooks are formed alternately on the front and back needle beds as shown by S2 in FIG. 2 within the knitting width of the tubular knitted fabric 101 (see FIG. 5B). Then, using these hooks as a foothold, the yarn feeder 9 is introduced in addition to the yarn feeder 8, and the left sleeve 12 and the cylinder portion 15 which are two independent branch cylinder portions are knitted out (see FIG. 5C). Furthermore, hooks are alternately formed on the front and back needle beds within the knitting width of the cylindrical portion 15 (see FIG. 5C), these hooks are used as a foothold, and the yarn feeder 7 is introduced in addition to the yarn feeder 9. The body 11 and the right sleeve 13 which are two independent branch cylinder parts are created (see FIG. 5D). Thereafter, as shown in FIG. 5 (E), if the body 11 and the sleeves 12 and 13 are knitted, the sweater 10 in which a heel is formed at the crotch position between the body 11 and the sleeves 12 and 13 is knitted. be able to. In addition, you may form the three branch cylinder parts of the body 11, the left sleeve 12, and the right sleeve 13 from the cylindrical knitted fabric 101 at once.

  On the other hand, if the sock 20 shown in FIG. 6A is to be knitted, the five torso 205, which is an integrated cylindrical portion, is knitted from the mouth of the sock 20. Next, hooks are alternately formed on the front and back needle beds within the knitting width of the five cylinders 205 (see FIG. 6B), and the four cylinders that are independent two branch cylinders using these hooks as a foothold. 204 and a little finger pouch 25 are knitted (see FIG. 6C). After the four cylinders 204 and the little finger pouches 25 are knitted for a predetermined number of courses, the four cylinders 204 are defined as a new integrated cylinder part, and the stitches are alternately placed on the front and back needle beds within the knitting width of the integrated cylinder part. It is formed (see FIG. 6D). Then, using these hooks as a foothold, the three barrels 203 which are two independent branch tube portions and the finger bag 24 of the ring finger are knitted (see FIG. 6E). Thereafter, the three cylinders 203 are defined as a new integrated cylinder, the two cylinders 202 and the middle finger pouch 23 are knitted, and the two cylinders 202 are defined as a new integrated cylinder, and the thumb pouches are defined. 21 and index finger finger bag 22 can be knitted so as to knitting socks 20 having a heel formed at the crotch position of each finger bag 21-25. Note that five finger bags 21 to 25 may be formed from the five cylinders 205 at a time.
