Description

Manufacturing method of shoes upper and shoes upper

The present invention relates to a shoe upper comprising a knitted fabric and a method of manufacturing the shoe upper.

The shoe has a sole cover which covers the sole of the wearer and a shoe upper which has an instep cover covering the part of the wearer's foot. In the outdoor shoes, an outer sole made of synthetic resin is attached to the sole cover of the shoes upper. In recent years, it has been attempted to manufacture a shoe upper having a light weight and excellent fit by constituting most of the shoes upper as a knitted fabric.

For example, in Patent Document 1, it has been attempted to fabricate shoes with high productivity by forming an in-one cover constituting a shoes upper as a single knitted fabric. In the case of manufacturing a shoes upper using the in-stap cover disclosed in Patent Document 1, the shoes cover is joined by sewing the separately prepared in-sit cover and the sol cover, thereby completing the shoes upper.

≪ Embodiment 1 >

"Full Configuration"

In Embodiment 1, an example of manufacturing the shoes upper 1 shown in Figs. 1A, 1B, 2A, and 2B will be described. The shoe upper 1 is a knitted fabric knitted with a knitting yarn at least partly made of a thermally fusible yarn and has a sole cover for covering the soles of the wearer's foot, (2), and an instep cover (3) covering the instep side of the wearer and formed with an insertion port (4). An outer sole (not shown) made of resin or the like may be attached to the outside of the solenoid cover 2 in the shoe upper 1. 2A and 2B, the brush cover 2 is viewed from the side for the sake of convenience, but the brush cover 2 is in a substantially invisible state on the side surface.

The insertion port 4 of the shoe upper 1 of the present embodiment is extended in a slit shape toward the toe side and a tongue 5 is formed at the end of the slit groove. In addition, eyelets 6 for passing the shoelace are formed at positions on both sides of the slit in the in-situ cover 3. The tongue (5) and eyelet (6) are arbitrary configurations.

The shoe upper 1 having the above-described configuration is a knitted fabric knitted using a weft knitting machine and has a three-dimensional shape according to the shape of the wearer's foot. Particularly, the heel side portion and the toe side portion of the shoe upper 1 are in a three-dimensional shape corresponding to the foot shape. The reason why the shoe upper 1 is formed in a three-dimensional shape is that the shoe upper 1 is divided into a hock knitted fabric 10 and a body knitted cloth 11 as shown in a manufacturing method of a shoe upper, This is because the body knitted fabric 11 is knitted after the knitting yarn 10 is knitted. 1A and 1B, a knitting width direction (a direction in which stitches are arranged in the longitudinal direction of the needle bed) of the knitting fabric 10 and the body knitting fabric 11 is defined as a thin line, Respectively. In other words, the direction orthogonal to the fine line is the wale direction. Here, the tongue 5 is a knitted fabric, but the knitting width direction is omitted in Figs. 1A, 1B, 2A, and 2B.

"Heel knitting pattern"

The heald knitted fabric 10 is a knitted fabric that covers a portion extending from the Achilles tendon of the wearer to the heel. The knitting start portion 10s of the hitting knitting yarn 10 is arranged on the side of the sole cover 2 in such a state that the knitting start portion 10s is folded in two at the center in the knitting width direction (see Fig. More specifically, the central portion (see the blackened arrow) of the two-folded knitting start portion 10s is disposed on the heel side, and both ends (see the arrows in the rim of the frame) are disposed on the toe side. The line (the second line L2) folded back to the knitting start portion 10s in two directions extends in a straight line toward the toe. On the other hand, the knitting end portion 10e of the heald knitted fabric 10 forms a part of the heel side of the insertion opening 4 formed above the instep cover 3 (see Fig. 1A).

The knitting starting portion 10s of the knitting fabric 10 is knitted in a substantially trapezoidal shape having a width wider than the knitting end portion 10e. 1 (a), the left edge portion extending from the vicinity of the center of the soles of the sole at the boundary between the sol cover 2 and the in-stap cover 3 to the insertion port 4 10a and the right side edge portion 10b are inclined toward the heel side together. 1B, the left side edge portion 10a (right side edge portion 10b) extending from the center portion of the solenoid cover 2 toward the left (right) side is inclined toward the heel side. The heald knitted fabric 10 may be formed in a substantially triangular shape. In this case, both side edges 10a and 10b are inclined toward the heel side.

"Body knitting fabric"

The body knitted fabric 11 is knitted continuously to the left side edge portion 10a and the right side edge portion 10b of the heald knitted fabric 10 and at the position of the edge portions 10a and 10b, The end stitch in the knitting width direction of the body 10 and the end stitch in the wale direction of the body knitted fabric 11 are connected. As a result, the heald knitted fabric 10 and the body knitted fabric 11 are mutually supported, and the heel side portion of the shoes upper 1 is shaped into a three-dimensional shape.

The left knitted fabric 10 is knitted with the left knitted fabric 11 which is continuous to the left side edge 10a of the knitting fabric 10 and the left knitted fabric 11 which is continuous to the right side edge 10b of the knitting fabric 10, 11 are connected without seam at a position near the foot of the side of the instep cover 3 as shown in Fig. 1A. The portion where the left portion 11L and the right portion 11R are not connected forms the insertion port 4 together with the knitting completion portion 10e of the heald knitted fabric 10. On the other hand, on the sole cover 2 side, a seam (toe side joining portion 13) to which the left side portion 11L and a part of the toe side of the right side portion 11R are connected by knitting is formed. The toe side joining portion 13 (The first line L1 to be described later) are connected by sewing instead of knitting.

The toe side joining portion 13 is formed by joining the edge portion on the wale side end side of the body knitted fabric 11 to the center side in the knitting width direction of the body knitted fabric 11 and joining it. More specifically, the edge portion on the wale-direction end side of the left portion 11L of the body-woven fabric 11 and the edge portion on the wale-direction end side of the right portion 11R of the body- The to-be-joined portion 13 is formed. By this toe-side joining portion 13, the front end portion of the body-knitted fabric 11 is shaped in such a shape as to cover the toe of the wearer.

The left side edge portion 11a and the right side edge portion 11b in the knitting width direction of the body knitted fabric 11 which has been returned to the soles cover 2 side by the formation of the toe side joint portion 13 are in a state of being in contact with each other. The first line L1 extending in a straight line from the left side edge portion 11a to the right side edge portion 11b extends in a straight line so that the knitting start portion 10s of the above- 2 line (L2). That is, in the shoe upper 1 of the present embodiment, the sewing portion 14 for sewing the left and right knitted fabrics by sewing is formed at the position of the soles cover 2.

&Quot; Organized tissue of the inset cover "

At least a part of the shoes upper 1 (the heel knitted fabric 10 and the body knitted fabric 11), in this embodiment, the entire shoe upper 1 is knitted using front and rear needle beds It is composed of thick knit organization. The method of knitting a thick knitted fabric is not particularly limited. It is possible to knit a thick knitted fabric by appropriately combining knitting using front and back needle beds such as rib knitting and tubular knitting. Such a knitted structure is thicker and stronger than a knitted fabric (for example, a plain stitch structure) knitted by using any one of the front and rear needle beds. If the shoe upper 1 of the shoe in which the load is applied in use is made of a thick knitted structure, the shape of the shoe upper 1 is not easily disturbed and the shoe upper 1 having excellent durability can be obtained. Here, the fact that the front and back needle beds can be used for knitting a thick knitted fabric means that the left portion 11L and the right portion 11R are arranged in the longitudinal direction of the needle bed, as shown in the knitting process described later with reference to Fig. 3 Because they are arranged and knitted.

"Manufacturing method of shoes upper"

The shoe upper 1 includes a knitting process for knitting the heald knitted fabric 10 and the body knitted fabric 11, the first line L1 and the second line L2 arranged on the sol- A sewing step for sewing, and a heat treatment step for heat-treating the shoes upper 1.

[Knitting Process]

In the knitting process, the heald knitted fabric 10 is knitted using at least a two-bed flat knitting machine having a pair of front and rear needle beds, and then the body knitted fabric 11 is knitted. Of course, these knitted fabrics 10, 11 may be knitted with a four-bed flat knitting machine.

In the description of the knitting process, Fig. 3 is referred to. Fig. 3 is a schematic view showing a knitting procedure of a knitting method. Arrows left in the frame of Fig. 3 indicate the progression direction of the knitting (same as the wale direction), and the horizontal lines in the parts 10 and 11 indicate the knitting width direction (the direction in which the stitches are arranged). In addition, in the figure, an uppercase letter is added to a part of a knitting element.

First, the heald knitted fabric 10 is knitted (corresponding to step?). Concretely, a knitting start portion 10s (see point A-point B) of the knitting fabric 10 is knitted and a plurality of stitch rows (stitch row). At that time, the knitting width of the stitch row is gradually narrowed. The stitches and the right side edge portion 10b (see point B-point D) arranged at the left side edge portion 10a (see point A-point C) in the knitting width direction of the obtained heel woven fabric 10 The stitches to be arranged are put on the needle bed. On the other hand, the knitting end portion 10e (see the point C-point D) which is the wale-direction end portion of the knitting fabric 10 becomes narrower than the knitting start portion 10s. The knitting end portion 10e is removed from the needle bed by a bind-off process or the like.

Herein, when knitting the heald knitted fabric 10, the inside widening may be performed at at least two places with the central portion in the knitting width direction of the heald knitted fabric 10 interposed therebetween. For example, the inner width is increased at two places near the center in the knitting width direction indicated by the double-dashed line in the figure and two places outside the knitting width direction than the two knitting positions. The inner width increasing means a knitting operation in which the knitted fabric is stretched within the knitting width of the knitting fabric. For example, a known inner width stretch forming a split stitch or a stitch hooked by the knitting needle Can be used. By increasing the inner width in knitting the heald knitted fabric 10, the heald knitted fabric 10 becomes bulged, and the shape of the heald knitted fabric 10 can be changed to a shape corresponding to the shape of the foot.

The left part 11L of the body-woven fabric 11 starts to be knitted from the position of the point C, and the knitting is started from the position of the point C, The knitting of the right portion 11R of the body-woven fabric 11 is started from the position of the point D (corresponding to the step?) In succession to the knitting widthwise right side edge portion 10b of the knitted fabric 10. The left portion 11L and the right portion 11R are knitted using respective feeding ports.

The left side portion 11L and the right side portion 11R of the body knitted fabric 11 are formed on the needle bed so as to be tapered toward the end of the body knitted fabric 11 after the step & And knitted in an arrayed state (process?). In knitting the body knitted fabric 11, after the knitting of the shoe upper 1 is completed, the heald knitted fabric 10 is folded in half at the center in the knitting width direction, The right side edge portion 11b in the knitting width direction of the left side edge portion 11a and the right side portion 11R in the knitting width direction of the left side portion 11L when the left side portion 11L and the right side portion 11R are folded in the thickness direction, The knitting width of the left side portion 11L and the knitting width of the right side portion 11R are adjusted so as to have a straight line shape (see Figs. 2A and 2B). In adjusting the knitting width, the width and height of the shoes upper 1 are also considered. The left portion 11L and the right portion 11R do not have to be symmetrical, and it is preferable that the knitting widths of the left portion 11L and the right portion 11R are different in accordance with the shape of the foot. Here, the first line L1, which is located between the left part 11L and the right part 11R, may be deviated from the center of the brush cover 2 to the left or right as long as the first line L1 is straight.

In the process y of the present example, the tongue 5 and the eyelet 6 are also formed. The tongue 5 starts to be knitted between the left portion 11L and the right portion 11R (refer to the point G-point H), and is connected to the body knitted fabric 11 when the length becomes a certain length . In addition, the eyelets 6 can be formed by nose reduction or the like.

The body knitted fabric 11 to be knitted in the process? Is knitted so as to have a tapered shape toward the tip of the foot as described above. Concretely, the knitting width of the body knitting fabric 11 is gradually reduced by flechage knitting or the like, so that the body knitting fabric 11 becomes tapered toward the end. By knitting in this manner, the left curved edge portion 11c (see the point I-point K) formed on the toe side of the left portion 11L and the right curved edge portion 11d (see the point I-point K) forming the toe side of the right portion 11R ) (See point J-point K) is coupled to the needle bed.

Also, in knitting the body knitted fabric 11, the knitting width may be increased after the knitting width of the body knitted fabric 11 is once shortened so that the portion on the toe side has a three-dimensional shape. For example, the knitting width of the body knitted fabric 11 is reduced so that stitches at the knitting width direction end portions are arranged at point a-point b indicated by chain double-dashed line, and body knitting is performed so that point- The knitting width of the cloth 11 is increased. By such a knitting, the portion of the body-woven fabric 11 on the toe side becomes a shape that is pushed to the inside of the paper, and the subsequent sewing work is facilitated.

The left curved edge portion 11c formed on the toe side of the left portion 11L and the right curved edge portion 11d forming the toe side of the right portion 11R are formed by the process 11, (Corresponding to step < RTI ID = 0.0 > 8). ≪ / RTI > This step? Can form the toe-side joining portions 13 shown in Figs. 1A, 1B, 2A, and 2B, so that the toe portion of the shoes upper 1 can have a three-dimensional shape.

The method of joining both curved edge portions 11c and 11d is not particularly limited. For example, a method of joining two curved marginal portions 11c and 11d by knitting a knitted fabric for joining both curved marginal portions 11c and 11d or a method of joining stitches of both curved marginal portions 11c and 11d And a method of direct bonding by knitting. In the former case, the stitch excluding the stitch at the boundary side end portion of the left curved edge portion 11c is moved to the boundary side and the stitch except the stitch at the boundary side end portion of the right curved edge portion 11d is moved to the boundary side. By this movement, a double stitch embroidering two stitches at the border side end portion of the left curved edge portion 11c and a double stitch embroidering two stitches at the border side end portion of the right curved edge portion 11d Stitches are formed. Followed by knitting two new stitches continuing in the wale direction of each of the two double stitches. The stitches on the border side end portion of the left curved edge portion 11c are superposed on the new stitch on one side and the stitches on the boundary side end portion of the right curved edge portion 11d are superimposed on the other stitch, And forming two new stitches successive to each pair of double stitches is repeated until the stitches of both curved edge portions 11c and 11d are eliminated. On the other hand, in the latter case, the stitches at the border side end portion of the left curved edge portion 11c and the stitch at the border side end portion of the right curved edge portion 11d are directly superimposed, and a new stitch is formed in the double stitch.

The shoe upper 1 of Figs. 1A, 1B, 2a, and 2B having a heel side portion and a toe side portion formed in a three-dimensional shape and composed of a thick knitted structure can be knitted by the steps? . At this point, since the first line L1 and the second line L2 of the shoes upper 1 are not yet joined, the next sewing step is performed.

[Sewing Process]

In the sewing process (corresponding to the process epsilon of the present invention), the first line L1 is arranged between the left side edge portion 11a and the right side edge portion 11b in the knitting width direction of the body knitted fabric 11, And the second line (L2) folded back to the knitting start portion (10s) of the cloth (10) is joined by sewing. As a result, it is possible to complete the shoes upper 1 having the straight sewing portion 14 shown in Fig. 1B.

Here, the first line (L1) and the second line (L2) to be sewn are arranged in a linear shape as shown in Figs. 2A and 2B. This is because the knitting widths of the left portion 11L and the right portion 11R of the body knitting fabric 11 are adjusted so as to be the same. Since the sewing of the straight line can be easily performed without requiring a special skill to the sewing worker, the shoes upper 1 of the present embodiment is excellent in productivity. Further, in the shoe upper 1 of the present embodiment, it is not necessary to sew the shoe upper 1 in a shape other than the sewing portion 14 in order to make the shoe upper 1 into a three-dimensional shape. Productive.

A reinforcing member or a decorative member may be attached to the shoes upper 1 by sewing. For the sake of convenience, sewing of the reinforcing member or the decorative member is different from sewing of the shoes upper 1 in a three-dimensional shape.

[Heat treatment process]

The shoes upper 1 after sewing may be heat-treated by sandwiching it with a vertebra. By fusion bonding the knitting yarn which is a knitting yarn used for knitting the shoe upper 1 by heat treatment, the shoe upper 1 can be molded in three dimensions. Further, the stitches are fused together by the hot-melt bonding yarns to provide a sturdy shoes upper 1 having appropriate flexibility.

[Other Processes]

The shoes upper 1 after the heat treatment is composed of a thick knitted structure and since the soles cover 2 is already integrated, it can be used as it is. Of course, a decoration member, a reinforcing member, an insole, an outer sole, and the like may be attached to the shoes upper 1. Since the shoe upper 1 of the present embodiment has a three-dimensional shape corresponding to the shape of the foot, it is possible to easily attach the insole, the outer sole, and the like.
