Description

[0001] METHOD FOR KNITTING KNITTED FABRIC [0002]

The present invention relates to a knitting method of a knitting fabric (knitting fabric) knitting a knitting start portion by using a weft knitting machine and knitting a base knitting shoulder continuously to the knitting start portion.

In the case of knitting a knitted fabric using a weft knitting machine, first, the knitting start portion is knitted, and the base knitting shoulder which becomes the main body of the knitted fabric continues to be knitted in the wale direction (wale direction) of the knitting start portion. By knitting the knitting start portion, it is possible to knit a base knitting shoulder portion in which the stitches of the base knitting around portion are not loosened. Here, when the knitting start portion is knitted, a draw thread stitch row is knitted by a draw thread different from the knitting start portion, and the knitting start portion is knitted successively to the draw thread stitch row There is also. The draw thread is excluded from the knitted fabric after knitting of the knitted fabric is completed. That is, in the finished knitted fabric, the knitting start portion is the start end of the knitted fabric.

As a technique for knitting a knitting start portion, for example, a technique described in Patent Document 1 is known. For example, in FIG. 4 of Patent Document 1, a stitch row is knitted in a zigzag form on the front and back needle beds, and the stitch row is stitched to the needle bed After one stitch row (one side stitch row) connecting a plurality of stitches in the course direction (course direction) is knitted, the other stitch row connecting the plurality of stitches coupled to the other needle bed in the course direction The other side stitch row is formed by tubular knitting to form a knitting start portion.

Japanese Patent Application Laid-Open No. 2015-63765

Since the knitting start portion of the related art has a portion knitted by knitting, the knitting start portion tends to be thicker than the base knitting around portion. Also, in the case where the knitting start portion is less likely to be shrunk due to knitting by the knitting, and the base knitting will be made into a knitted structure that is easy to shrink in the knitting width direction such as a rib structure, Side is likely to spread in the knitting width direction.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and one of its objects is to provide a knitting method of a knitting fabric capable of knitting a knitted fabric which does not increase the knitting start portion. Another object of the present invention is to provide a knitting fabric knitting method in which the knitting start portion is hard to spread in the knitting width direction.

The knitting method of the knitted fabric of the present invention is a knitting method,

A knitting start portion is knitted by using a weft knitting machine having a first needle bed and a second needle bed facing each other in the front and back direction, In which a base knitted fabric portion is knitted continuously,

The knitting start portion

A set-up stitch row serving as a start end portion of a knitted fabric is stitched on one of the needle beds (either one of the first needle bed and the second needle bed) (A) in which the stitches are alternately stitched to the needle beds (the other one of the first needle bed and the second needle bed)

A knitting yarn (knitting yarn) for supporting a sinker loop of the knitting start stitch row is provided between a plurality of stitches coupled to the one needle bed in the knitting start stitch sequence and a plurality of stitches coupled to the other needle bed, A step (B) of inserting a thread,

(C) of knitting a new stitch row for fixing supporting the knitted loop of the knitting start stitch row continuously in the wale direction (wale direction) of the knitting start stitch row

.

Here, in the knitting start stitch row in which one needle bed and the other needle bed in the step (A) are alternately stitched one by one, stitches are formed alternately one by one on the needle bed and the other on the other needle bed Or may be obtained by dividing a knitting start stitch row knitted on one of the needle beds into one needle bed and the other needle bed. The knitting yarn used in the step (B) may be different from the knitting yarn used for knitting the knitting start stitch row, or may be the same. The knitting yarn used for knitting the knitting yarn and the fixing stitch row used for knitting the knitting start stitch row may be the same or different.

As a form of the knitting method of the knitted fabric of the present invention, the knitting used in the step (B) includes a form including elastic yarn.

As a form of the knitting method of the knitted fabric of the present invention, there is a form of knitting the knitting start portion connected in a tubular form.

As a form of the knitting method of the knitted fabric of the present invention, the knitting yarn may be inserted into the base knitted shoulder portion by inlay knitting when the knitted base knitting shoulder is knitted.

The inlay knitting is a method of dividing the stitches of the base stitch row on the front and rear needle beds and sandwiching the knitting yarn between the divided stitches. For example, Japanese Patent Application Laid-Open No. 60-199953 and Japanese Patent Laid- A known knitting method as described in JP-A-2007-277738.

According to the knitting method of the knitted fabric of the present invention, the knitting yarn is inserted between the stitches divided into the front and back of the knitting start stitch row constituting a part of the knitting start portion, and each sinker loop of the knitting start stitch row is pressed to support the sinker loop . In addition, by supporting the knit loop of the knitting start stitch row with the fixing stitch row, the support of the sinker loop by the knitting yarn is fixed, and the loosening of the knitting start portion can be prevented. That is, by the simple method of inserting the knitting yarn between the front and rear stitches of the knitting start stitch row without the previously required knitting of the knitting stitch, it is possible to prevent the knitting start portion, which is the starting end of the knitting fabric, from unwinding. The knitting start portion in which no bag knitting structure is present is completed to be thinner than the conventional knitting start portion. The knitting start portion shrinks with the contraction of the base knitting surrounding portion because the knitted knitting structure which is difficult to expand and contract in the knitting width direction is not present at the knitting start portion and therefore the starting end portion of the base knitting around portion So that it is unlikely to spread in the knitting width direction.

By arranging the knitting yarn including the elastic yarn between the stitches of the knitting start stitch row, the stretchability of the knitting start portion can be further increased.

In the case of knitting a tubular base knitting ambipad, the knitting start portion is also knitted into a tubular shape. By knitting the tubular knitted fabric starting portion by the knitting method of the knitted fabric of the present invention, it is possible to effectively prevent the leading end of the tubular base knitted fabric portion from spreading in the truncated form.

By inserting the knitting yarn that is the same as the knitting yarn used in the knitting start portion into the base knitting surrounding portion, the base knitting will and the knitting start portion have the same structure, so that the boundaries of both can be made inconspicuous.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a knitting process diagram of a knitting start portion in a knitted fabric according to Embodiment 1. FIG.
Fig. 2 is a process chart of knitting a base knitting will in the knitted fabric according to Embodiment 1. Fig.

&Lt; Embodiment 1 >

In Embodiment 1, an example of knitting a tubular knitting start portion by using a four-bed flat knitting machine will be described. Further, the flat knitting machine used for knitting may be a two-bed flat knitting machine, and the knitting start portion may not have a tubular shape.

1 is a knitting process chart for knitting a knitting start portion of a knitted fabric. 1 denotes the number of the knitting process, the reverse triangular mark denotes the feed mouths 8 and 9, the FD denotes a lower front needle bed (the first needle FU is an upper front needle bed (first needle bed), BD is a lower back needle bed (second needle bed), BU is an upper back needle bed needle bed (second needle bed). Upper case letters indicate the position of knitting needles. The arrows in the drawing indicate the movement of the stitches, and the portions where knitting operations are actually performed in each knitting step are indicated by bold lines.

S0 is a state in which drawing thread stitch rows 1 and 2 knitted with drawing threads are combined with knitting needles B to K of BD and knitting needles B to K of FD, Respectively. From this state, the knitting start portions 3 and 4 (refer to S4 and S6) connected in a tubular form continue in the wale direction (wale direction) of the draw thread stitch rows 1 and 2. Here, in the case of using a weft knitting machine equipped with a movable sinker (see Japanese Unexamined Patent Application Publication No. 2015-132026) that presses a knitting yarn when knitting, the draw thread stitch rows 1 and 2 The knitting start portions 3 and 4 may be knitted.

In S1, the stitches of the knitting needles C, E, G, I and K are moved to the knitting needle of the facing FU from the draw thread stitch row (1) (So) D, F, H) of the BD are moved to the right side of the drawing so that the knitting start stitch row 10 continuing in the wale direction of the draw thread stitch row 1 is knitted by the knitting needles B, D, F, H , J) and knitting needles (C, E, G, I, K) of the FU. The knitting yarn Y8 is a yarn different from the draw yarn.

Here, it is also possible to knit the knitting start stitch row 10 in the BD without moving a part of the draw thread stitch row 1 to the FU (the same applies to the knitting start stitch row 20 described later).

In step S2, stitches of the knitting needles B, D, F, H and J are moved to knitting needles of the opposed BUs in the draw thread stitch row 2 (So) coupled to the FD, The stitches of one knitting start stitch row 10 are returned to BD. In the case where the draw thread stitch row 1 is not moved from S1 to FU, it is not necessary to return the stitches of the knitting start stitch row 10 to BD.

In S2, the yarn feeder 8 is moved to the left so that the knitting start stitch row 20 continuing in the wale direction of the draw thread stitch row 2 is knitted by the knitting yarn Y8 by knitting needles K, I, G , E, C) and knitting needles (J, H, F, D, B) of BU.

In S3, the stitches of the knitting needles C, E, G, I, K are shifted to the knitting needle of the opposing FU among the stitches of the knitting start stitch row 10 to be joined to the BD (knitting of the knitting start portion 3 And the stitches of the knitting start stitch row 20 formed in the BU in S2 are returned to the FD. The stitches of the knitting start stitch row 10 are alternately stitched to BD (one needle bed) and FU (the other needle bed) by the movement of stitches of the knitting start stitch row 10 The stitches are engaged one by one (combined state of 1x1). If the knitting start stitch row 10 is in the engaged state other than the 1x1 engagement state (for example, 1x2 engagement state), adjacent stitches in the knitting start stitch row 10 are joined to the same needle bed And therefore, such a joined state is not provided.

In S3, the yarn feeder 9 for feeding the knitting yarn Y9 is moved in the rightward direction so that the stitches of the knitting start stitch row 10 joined to the front and back needle beds, that is, BD, The knitting yarn Y9 for supporting the sinker loop of the knitting start stitch row 10 is inserted between the stitches of the stitch row 10 (in the step (B) of knitting of the knitting start portion 3 Equivalent).

The material and shape of the knitting yarn Y9 are not particularly limited. For example, as the knitting yarn Y9, a knitting yarn including an elastic yarn may be mentioned. If the knitting yarn Y9 including elastic yarn is used, the knitting start portion 3 can have high stretchability. Here, as the knitting yarn to be inserted into the knitting start stitch row 10, a knitting yarn Y8 fed from the yarn feeding port 8 may be used. A tuck is made to the stitch (the knitting needle K of the FU) at the right end (right end) of the knitting start stitch row 10 so that the knitting yarn is not loosened in that case, It is preferable to form a stitch hooked by the knitting needle. In the case of forming the engaging stitch, the engaging stitch may be removed from the needle bed later than S5 described later.

D, F, H, and J) of the BD, the fixing stitch row 11 continuing in the wale direction of the knitting start stitch row 10 is moved in the rightward direction, (Corresponding to the step (C) of the knitting of the knitting start portion 3) on the knitting needles (C, E, G, I, K) The knit loop of the knitting start stitch row 10 is supported by the fixing stitch row 11 and the knitting yarn Y9 placed between the stitches of the knitting start stitch row 10 is released from the knitting start stitch row 10 . The knitting start portion 3 is constituted by the knitting start stitch row 10, the knitting yarn Y9 disposed between the knitting stitch rows 10 and the fixing stitch row 11 following the knitting start stitch row 10.

Unlike the example shown in the drawing, when the stitches of the knitting start stitch row 10 to be joined to the FU are returned to the BD, It is preferable to knit the stitch row 11 for use.

In step S5, the stitches to be bonded to the FUs are moved to the opposing BD knitting needles among the stitches in the fixing stitch row 11, and knitting needles B, D, F , H, and J are moved to the knitting needle of the opposing BU (corresponding to the step (A) of knitting of the knitting start portion 4). The stitches of the knitting start stitch row 20 are alternately stitched one by one to the FD (one needle bed) and the BU (the other needle bed) by the movement of the stitches of the knitting start stitch row 20 1 x 1 coupled state).

In S5, the yarn feeder 9 is moved to the left so that the stitches of the knitting start stitch row 20 and the knitting start stitch row 20, which are coupled to BU, between the front and back needle beds, The knitting yarn Y9 for supporting the sinker loop of the knitting start stitch row 20 is inserted between the stitching knitting stitch row 20 and the knitting start stitch row 20 (corresponding to the step (B) of knitting of the knitting start portion 4).

I, G, E and C of the FD and the knitting needles J, H, F, and B of the BU, the stitch row 21 for fixing which continues in the wale direction of the knitting start stitch row 20, D, B) (corresponding to the step (C) of knitting of the knitting start portion 4). The knit loop of the knitting start stitch row 20 is supported by the fixing stitch row 21 and the knitting yarn Y9 placed between the stitches of the knitting start stitch row 20 is released from the knitting start stitch row 20 . The knitting start portion 4 is constituted by the knitting start stitch row 20, the knitting yarn Y9 sandwiched between the knitting stitch rows and the fixing stitch row 21 following the knitting start stitch row 20. [

In S7, the stitches to be coupled to the BU in the stitches of the fixing stitch row 21 are moved to the opposing FDs. With the above-described knitting, the knitting start portion 3 coupled to the BD and the knitting start portion 4 coupled to the FD are connected in a tubular manner. Particularly, in this example, after the steps (A, B, C) concerning the knitting of the knitting start portion 3 are performed, the steps (A, B, C) Since the knitting yarn Y9 inserted into the knitting section 3 and the knitting yarn Y9 inserted into the knitting start section 4 are connected to each other, it is possible to effectively prevent the starting end of the knitted fabric from spreading in the truncated form .

Thereafter, the base knitting needles 5, 6 continuous in the wale direction of the knitting start portions 3, 4 are knitted. In this example, the knitting yarn Y9 used for knitting the knitting start portions 3 and 4 is knitted into the base knitted fabric portions 5 and 6 by inlay knitting. An example of such a combination will be described with reference to Fig. The method of viewing the drawing is the same as that of Fig.

In S10 of FIG. 2, the knitting start portions 3 and 4 shown in S7 of FIG. 1 are completed. From this state, in S11, the stitch of the knitting start portion 3 is divided into BD and FU, and the yarn feeder 8 is moved to the right to knit the base stitch row 50 succeeding the knitting start portion 3. [ The base stitch row 50 may be knitted as a stitch row constituting a part of the base knitting needles 5 and a knitting yarn fed from a feeding opening different from the feeding opening 8. [

Here, in the step S11, the stitches of the knitting start portion 3 are divided in the 1x1 engagement state, but they may be different distribution systems. The base knitting needles 5 and 6 are not loosened like the knitting start portions 3 and 4 at the start of the knitting fabric and do not loosen even if they are engaged in a state other than the 1x1 coupling state to be. For example, the stitches of the knitting start portion 3 may be divided so as to be in a combined state of 1x2, 2x1, and 2x2. Also, after the base stitch row 50 is knitted, the stitches of the base stitch row 50 may be divided into BD and FU.

In S12, the yarn feeder 9 is moved to the right, the knitting yarn Y9 is inserted between the front and back needle beds, and the knitting yarn Y9 is placed between the stitches of the base stitch row 50 arranged on the BD and FU .

In S13, the stitches of the base stitch row 50 connected to the FU are moved to the opposing BD knitting needles, and the stitches of the knitting start portion 4 coupled to the FD are divided into FD and BU, 8 are moved to the left side to knit the base stitch row 60 subsequent to the knitting start portion 4. [ The base stitch row 60 is a stitch row constituting a part of the base knitting portion 6.

In S14, the yarn feeder 9 is moved to the left to insert the knitting yarn Y9 between the front and back needle beds, and the knitting yarn Y9 is placed between the stitches of the base stitch row 60 arranged on the FD and BU . Thereafter, by repeating the knitting similar to that of S11 to S14, the base knitting needles 5 and 6 incorporating the knitting yarn Y9 can be knitted.

As shown in the knitting step described above, since the knitting start portions 3 and 4 are not knitted at the time of knitting, the knitting start portions 3 and 4 are not conspicuous, The knitting start portions 3 and 4 of the knitting yarns 5 and 6 are prevented from spreading in a trumpet shape so that the appearance of the knitted fabric can be improved. The knitting yarn Y9 used for the knitting start portions 3 and 4 is also used for inlaying the base knitting needles 5 and 6 so that the boundary between the knitting start portions 3 and 4 and the base knitting needles 5 and 6 It is not necessary to perform yarn out of the knitting yarn Y9 in the knitted fabric Y. This makes it possible to reduce the number of places for finishing the knitting yarn Y9 in the entire knitted fabric.
