Description

  The present invention relates to a knitting method of a knitted fabric for knitting a knitted fabric having a structure that is difficult to shrink.

  When knitting a knitted fabric that requires stretchability such as underwear, socks, and supporters with a flat knitting machine, elastic knitting yarn may be used. However, the knitted fabric knitted using the elastic knitting yarn shrinks as compared with the time of knitting. For example, when the width of the knitted fabric locked to the needle bed at the time of knitting is 100, the width of the knitted fabric removed from the needle bed may be 50 to 70 depending on the stretchability of the elastic knitting yarn. A knitted fabric that has shrunk excessively may tighten the wearer excessively and place a burden on the wearer. In view of such a problem, for example, Patent Document 1 proposes a knitting method for a knitted fabric in which the loop length of a stitch is adjusted according to the tension of an elastic knitting yarn.

International Publication No. 2004/094712

  In the knitting method of the knitted fabric of Patent Document 1, the loop length of the stitches is adjusted according to the tension of the elastic knitting yarn by using a flat knitting machine that previously holds the tension of the elastic knitting yarn as data. That is, the knitting method of the knitted fabric disclosed in Patent Document 1 is premised on the use of a flat knitting machine having a dedicated control system including a program, and can be used in a flat knitting machine that does not have such a control system. Can not. Therefore, there is a demand for a knitting method for a general-purpose knitted fabric that can knitted a knitted fabric that is less likely to shrink than during knitting even in a flat knitting machine that does not include a dedicated control system.

  Even when the knitted fabric is knitted using a knitting yarn that is not an elastic knitting yarn, the finished knitted fabric tends to shrink compared to the knitting due to the characteristics of the knit. Therefore, there is a demand for a knitting method for general-purpose knitted fabrics that can knitting a knitted fabric that is less likely to shrink than when knitting even when knitting yarns that are not elastic knitting yarns are used.

  The present invention has been made in view of the above circumstances, and one of its purposes is to provide a knitting method of a knitted fabric having a structure that is less likely to shrink than during knitting.

The knitting method of the knitted fabric of the present invention is a knitting method of a knitted fabric using a flat knitting machine that includes at least a pair of front and back needle beds and can transfer stitches between the front and back needle beds. -Process γ is repeatedly performed.
[Step α]... Select a part of stitches within a selection range of a predetermined width from the base stitch row locked to one needle bed as a starting stitch, and perform an extra for the selected starting stitch. . Here, the entire base stitch row may be set as the selection range of the starting stitch.
[Step β]... The starting stitch transferred to the other needle bed by the additional needle is superposed on a new stitch that satisfies the following condition I on one needle bed.
(Condition I) A stitch formed on the one needle bed in a state of being pulled out from the starting stitch by the extra.
[Step γ]... A knitting stitch continuous in the wale direction of each double stitch formed on one needle bed in step β is knitted, and the double stitches are fixed.
It is also possible to select the double stitch formed in the n-th process γ as the starting stitch in the (n + 1) -th process α.

  Here, the extra is a known knitting operation in which a starting stitch locked to one needle bed is transferred to the other needle bed and a new stitch drawn from the starting stitch is formed on one needle bed. (See Japanese Patent No. 2604653). For example, when the starting stitch is locked to the knitting needle X of the front needle bed, if the premium is added to the starting stitch, the starting stitch moves to the knitting needle Y (knitting needle opposite to the knitting needle X) of the rear needle bed. In the knitting needle X, a new stitch drawn from the starting stitch is formed.

  As a knitting method of the knitted fabric of the present invention, both the starting stitch and the new stitch can be knitted with elastic knitting yarn. For example, polyurethane can be used as the elastic knitting yarn.

  Examples of the knitting method of the knitted fabric of the present invention include a form in which the selection pattern of the starting stitch in the process α is a specific repeating pattern.

As a repetitive pattern, for example, a periodic pattern in which 1 to 3 starting stitches are arranged every other 1 to 3 stitches can be mentioned. For example, when the starting point stitch is “□” and the non-starting point stitch is “×”, the following patterns can be exemplified. Needless to say, the pattern is not limited to the following example as long as it is a regular repeating pattern.
[Exemplary 1] ××× □ × □ × □ × □ × □ ××××
[Example 2] XXXXXX
[Example 3] ××× □□ × □□ × □□ × □□ ××
[Example 4] ××× □□ ×× □□ ×× □□ ×××

  As a knitting method of the knitted fabric of the present invention, when repeating steps α to γ, at least the selection range of the starting stitch in the base stitch row is widened and the selection range of the starting stitch in the base stitch row is at least A form in which one is performed can be mentioned.

  As a knitting method for a knitted fabric of the present invention, a knitting needle provided in a needle bed is a composite needle comprising a needle body having a hook at a tip and a slider having two blades having a tongue formed at the tip, The form which uses the compound needle comprised so that the tongue provided in the front-end | tip of a slider can advance to the position beyond a hook by relative movement of a main body and a slider can be mentioned.

  The compound needle is a knitting needle that uses a tongue of a slider when transferring a stitch from one needle bed to the other needle bed, and does not include a transfer blade (for example, Japanese Patent No. 2917146). See). Due to the structure of such a compound needle, when transferring from the compound needle X of one needle bed to the compound needle Y of the other needle bed, the position of the compound needle X and the position of the compound needle Y in the knitting width direction Match. Therefore, when a premium is added to the starting stitch that is locked to the composite needle X, a new stitch that is drawn straight from the starting stitch transferred to the composite needle Y is formed on the composite needle Y. In contrast, in a knitting needle having transfer blades on the side surface of the needle body, the knitting needle on one needle bed and the knitting needle on the other needle bed are displaced in the knitting width direction. In the extra using the provided knitting needle, a new stitch drawn diagonally from the starting stitch is knitted.

  In the knitting method of the knitted fabric of the present invention, a premium is applied to the starting stitch. In the extra, the starting stitch is transferred from one needle bed to the other needle bed, and the loop length of the starting stitch is ensured. Further, in the knitting method of the knitted fabric of the present invention, the starting stitch is overlapped with the new stitch formed in the state pulled out from the starting stitch by the extra stitch, and the overlapping stitch composed of the starting stitch and the new stitch is fixed by the stop stitch. Is done. By overlapping the starting stitch and the new stitch drawn from the starting stitch due to the extra stitch, the starting stitch and the new stitch inhibit each other's contraction. As a result, the structure knitted by the knitting method of the knitted fabric of the present invention is less likely to shrink than during knitting. The knitting method of the knitted fabric of the present invention is particularly effective when knitting the knitted fabric using elastic knitting yarn. This is because the structure knitted with the elastic knitting yarn is easy to shrink, but with the knitting method of the knitted fabric of the present invention, a structure that is difficult to shrink can be knitted even when the elastic knitting yarn is used. Therefore, it is not necessary to significantly increase the number of stitches in consideration of the shrinkage amount of the tissue in order to knit a desired knitted fabric.

  Here, the knitting method of the knitted fabric of the present invention may be applied to the entire surface of the knitted fabric, or may be applied only to a specific region of the knitted fabric. In the former case, the overall knitted fabric is less likely to shrink than during knitting. In the latter case, a knitted fabric including a non-shrinkable part knitted by applying the knitting method of the knitted fabric of the present invention and other easily shrinkable parts can be knitted. The size of the knitted fabric can be easily adjusted by adjusting the proportion of the portion of the knitted fabric that is difficult to shrink. Further, as shown in the second embodiment, a three-dimensional knitted fabric in which a portion that is difficult to shrink can be knitted.

  By making the selection pattern of the starting stitch a specific repeating pattern, it is possible to make the stretchability of the portion of the knitted fabric that is difficult to shrink uniform. In addition, since the starting stitches are arranged in a regular repeating pattern, there is an effect that the appearance of the portion that is difficult to shrink is improved.

  When the steps α to γ are repeated, by increasing or decreasing the selection range for selecting the starting stitch in the base stitch row, the shape of the portion that is difficult to shrink in the knitted fabric can be changed to a desired shape. By adjusting the shape of the portion that is difficult to shrink, for example, a three-dimensional knitted fabric can be knitted along the shape of the human body like the knit pants of the second embodiment described later.

  According to the knitting method of the knitted fabric of the present invention using the compound needle, it is possible to improve the touch and appearance of a portion that is difficult to shrink. This is because a new stitch is drawn straight from the starting stitch in the premium using the compound needle.

Further, the knitting needles provided in the needle bed may be knitting needles provided with transfer blades.

<Embodiment 1>
Embodiment 1 demonstrates the example which applied the knitting method of the knitted fabric of this invention over the whole surface of a knitted fabric when knitting a knitted fabric using an inelastic knitting yarn. Specifically, the knitted fabric is knitted according to the following procedure.
[Procedure 1] Of the base stitch rows locked to the needle bed, the starting stitches of the qth stitch are selected for every p stitches, the stitches are added to the starting stitches, and the stitches not selected as the starting stitches are selected. Knit regular stitches in the wale direction. This procedure 1 corresponds to the n-th step α in the present invention (n is a natural number).
[Procedure 2] ... A double stitch is formed by superimposing the starting stitch on the new stitch drawn from the starting stitch by the extra. This procedure 2 corresponds to the n-th step β in the present invention.
[Procedure 3] ... The normal stitch knitted in Procedure 1 and the overlap stitch formed in Procedure 2 are used as a new base stitch row, the normal stitch is selected as the starting stitch, the premium is added to the starting stitch, A normal stitch that is continuous in the wale direction of the stitch not selected as the starting stitch (ie, the double stitch) is knitted. The former premium corresponds to the (n + 1) th step α in the present invention. The latter normal stitch knitting corresponds to the stop stitch knitting for fixing the double stitches, that is, the n-th step γ in the present invention.
[Procedure 4]... A double stitch is formed by superimposing the starting stitch on the new stitch drawn from the starting stitch by the extra in procedure 3. This procedure 4 is the same as the procedure 2 and corresponds to the (n + 1) th step β in the present invention.
Thereafter, the same knitting as in steps 3 and 4 may be repeated.

  FIG. 1 is a knitting process diagram when p and q in the above procedure are both “1”. In the figure, “S + number” in the left column indicates the number of the knitting process, and the right column indicates the stitching state of each stitch in each knitting process. The black dots in the right column are the knitting needles on the FB and BB, the alphabets A to K are the positions of the knitting needles, ○ is the old stitch, ● is the stitch knitted in each knitting process, ◎ is the double stitch, and the arrow is the stitch transfer direction Indicates. 2 shows a loop diagram of the knitted fabric knitted according to the knitting process diagram shown in FIG. 1, and FIG. 3 shows a photograph of the knitted fabric.

  S1 shows a state in which the stitches 1, 2, 3, 4, and 5 are locked to the knitting needles B, D, F, H, and J of the FB. This is a base stitch row 100. In the present embodiment, the knitting method of the knitted fabric of the present invention is performed according to a repeating pattern in which starting stitches are arranged every other stitch. Therefore, the stitches locked to the knitting needles B, F, and J of the FB in the base knitted fabric row 100 locked to S1 are selected as the starting stitches.

  In S2, while moving the yarn feeder to the left in the knitting width direction (left in the drawing), the stitches 5, 3, and 1 are increased, and the stitches 7 and 7 that are continuous in the wale direction of the stitches 4 and 2 are performed. 9 is organized. As a result of the increase, the starting stitches 5, 3, and 1 locked to the knitting needles J, F, B of the FB in S1 are transferred to the knitting needles J, F, B of the BB, and the knitting needles J, F, In B, stitches (new stitches) 6, 8, and 10 are formed. The new stitches 6, 8, and 10 are drawn straight from the starting stitches 5, 3, and 1, respectively.

  In S3, the starting stitches 5, 3, and 1 transferred to the BB are superimposed on the new stitches 6, 8, and 10 that are opposed to the starting stitches 5, 3, and 1 in the FB. As a result, the stitches 1; 10, 3; 8, 5; 6 are respectively locked to the knitting needles B, F, J of the FB (see also FIGS. 2 and 3). Here, the stitches 7 and 9 locked to the FB and the double stitches 1; 10, 3; 8, 5; 6 are set as a new base stitch row 100.

  In S4, while the yarn feeder is moved to the right in the knitting width direction, the stitches 9 and 7 are increased and the continuous stitches in the wale direction of the double stitches 1; 10, 3; 8, 5; (Stop stitches) 11, 13, 15 are knitted.

  In S5, the starting stitches 7, 9 transferred to the BB are superposed on the new stitches 14, 12 facing the starting stitches 7, 9 in the FB. As a result, the double stitches 9; 12, 7; 14 are respectively locked to the knitting needles D, H of the FB (see also FIGS. 2 and 3).

  After S5, if the knitting similar to S2 to S5 is repeated with the stop stitches 11, 13, 15 and the double stitches 9; 12, 7; 14 locked to the FB as the new base stitch row 100, good.

  According to the knitting process described above, as shown in FIGS. 2 and 3, a knitted fabric having a structure in which stitches are doubled can be knitted. The two overlapping stitches are a starting stitch and a new stitch drawn from the starting stitch due to the extra stitch, and the loop shape is maintained by the extra stitch. For this reason, the knitted fabric of the first embodiment is a knitted fabric having a smaller shrinkage rate than that at the time of knitting (that is, when the knitted fabric is locked to the needle bed).

<Embodiment 2>
In the second embodiment, an example in which a non-shrinkable tissue knitted according to the procedure described in the first embodiment is formed on a part of knit pants (knitted fabric) knitted using elastic knitting yarn such as polyurethane will be described.

  FIG. 4 is a schematic rear view of the knit pants. In this knit pants, the portion corresponding to the buttocks of the wearer (the portion surrounded by the two-dot chain line in the figure) is the present organization T1 knitted by the knitting method of the knitted fabric of the present invention, and the remaining portion is the conventional knitted fabric. This is a conventional tissue T2 (for example, a tengu tissue) knitted by the knitting method. Since the tissue T1 of the present invention is less likely to shrink than the conventional tissue T2, the tissue T1 of the present invention rises when the conventional tissue T2 shrinks, and becomes a three-dimensional knitted pant along the shape of the wearer's buttocks. With such a knit pant, the knit pant fits the wearer by tightening the tissue T2, and it is possible to avoid excessive tightening of the buttocks by the tissue T1 of the present invention. In addition, since the present organization T1 is an appearance-like organization similar to the Tendon organization (conventional organization T2), there is also an effect that the boundary between the present organization T1 and the conventional organization T2 is not conspicuous.

  Here, when knitting the present invention tissue T1 in the knit pants of FIG. 4, the selection range of the starting stitch in the base stitch row is increased or decreased, and the shape of the present invention tissue T1 is set to a shape corresponding to the buttocks. As a result, the knit pants shown in FIG. 4 are fitted with a rounded collar shape.

  In addition to the knit pants described above, the knitting method of the knitted fabric of the present invention may be applied to supporters of elbow joints and knee joints. For example, if the knitting method of the knitted fabric of the present invention is applied to the part corresponding to the elbow or knee in the supporter and the conventional knitting method of the knitted fabric is applied to the other part, excessive tightening by the supporter can be avoided. Can do.
