Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stocking with a handle and a method of producing the same, which is controlled by a computer.

[0002]

2. Description of the Related Art In recent years, "making your legs look slender" or "strong"
Supporting types of panty hose or stockings (hereinafter, both are collectively referred to as "stockings") are widely available with the catchphrases such as. The support type stocking uses a conventional woolly nylon as a raw yarn by using a polyurethane elastic yarn as a core yarn and using a raw yarn with a strong compressive force obtained by covering a nylon yarn with this, or by devising a knitting method. It has a stronger tightening force on the legs than stockings.

Such a support type stocking is usually a high-speed knitting machine (usually 600 to 1500 rpm).
Is knitted in. An example of this knitting machine is shown in FIG. In the figure, 2 is a main body part in which a knitting mechanism part is incorporated,
3 is pan roll (or corn roll, cheese roll, etc.)
It is a stand (four front and rear are erected) for holding the thread 4 thus formed. Also, 5 is a tension device, and 4 threads 4
After the outer peripheral surfaces of the tension rollers 6 arranged in one horizontal line are rotated once and then introduced into the yarn feeder (not shown), the tension of the yarn 4 is constantly maintained.
Reference numeral 7 is a motor for rotationally driving the tension roller 6, and 8 is a frequency setting device for setting the rotation speed of the motor.

By the way, conventionally, in the above-mentioned support type stocking, it has been performed to give a patterned stocking by applying a simple repeating pattern using the high-speed knitting machine, but recently, a more complicated It has been proposed to provide a high quality watermark pattern. For example, FIG.
As shown in FIG. 5, in the panty hose, a product in which a gorgeous watermark pattern 1 is inserted at the boundary between the panty part 20 and the leg part 21 or, as shown in FIG. 5, in the stockings up to the thigh, a watermark is provided around the thigh part. A product with pattern 1 is being developed.

[0005]

However, since it is difficult to knit such a complicated watermark pattern with a high-speed knitting machine, in this case, a low-speed knitting machine equipped with computer control means (usually 200- 300 rpm) is used. However, when the support stocking is knitted using the low-speed knitting machine, even if the tension device 5 (see FIG. 6) of the high-speed knitting machine is used as it is to apply tension evenly to the thread 4, Since the compressive force is strong, it has been found that the yarn may be pulled out or the tension of the yarn 4 may be uneven. Therefore, the product obtained is
Horizontal stripes were generated based on the irregular stitches, which was unattractive.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an excellent patterned stocking that is patterned by computer control, has uniform stitches, and has a good appearance, and a manufacturing method thereof.

[0007]

In order to achieve the above object, the present invention is a support type patterned stocking in which at least a part of the cloth is patterned by computer control, and the patterned stocking is adapted to the shape of the foot. Each part knitted by changing the tension of the thread for each predetermined area and knitted with the same tension is composed of uniform stitches in which the dimensional error of the course width constituting the part is within 10%. A method of knitting a support type patterned stocking using a stocking knitting machine that performs patterning by computer control is described in the first gist of the present invention, in which a plurality of yarn feeders of the knitting machine are provided. When the yarns are supplied, each yarn first goes around the outer peripheral surface of the first tension roller and then passes through the intermediate guide to the outside of the second tension roller. After the surface is rotated once, it is supplied to the yarn feeder, and at least one of the first and second tension rollers is rotationally driven at a predetermined rotation speed, and the rotation speed is controlled by the size control means of the knitting machine. The second gist is the manufacturing method of patterned stockings that are changed while synchronizing with the set count.

As used herein, "uniform stitches with dimensional error of course width within 10%" means that the obtained fabric is pulled vertically and horizontally to widen the stitches and then the microscope is used. The width A of each course is measured, and the error between them is within 10%.

[0009]

Next, an embodiment of the present invention will be described.

First, the patterned stocking to which the present invention is applied has a watermark pattern 1 formed on a part of its material as shown in FIGS. 4 and 5, or the watermark pattern 1 is formed on the whole. It is a patterned stocking. And, the patterning must be done by computer control, and must be a support type stocking.

As the thread used for obtaining the support type stocking, various kinds of thread conventionally used for the support type can be used. Examples include SCY (single covered yarn) and DCY (double covered yarn). Of course, there is no problem even if these covering yarns and other yarns are aligned and knitted or knitted every predetermined course.

In order to knit the patterned stocking of the present invention, a special low-speed knitting machine equipped with computer control means is provided with a special tension device 10 as shown in FIGS. 1 and 2, for example. is necessary.

The tension device 10 is a modification of the tension device 5 (see FIG. 6) used in the conventional high-speed knitting machine. The tension rollers 6 which are conventionally arranged in a horizontal row are arranged in two upper and lower stages. An intermediate guide 12 is provided between each pair of upper and lower tension rollers 6, 6 '. The upper tension roller 6 is driven to rotate by a motor 7, and the lower tension roller 6'is driven to rotate.

Reference numeral 13 is a cymbal tension for introducing the thread 14 into the tension device 10, and a predetermined tension is applied to the thread 14 by the pressing bias of a compression coil spring 13a provided on the right side of the drawing. Has become. Reference numeral 15 is a guide for guiding the yarn 14 to the yarn feeder.

Therefore, when knitting the patterned stocking of the present invention, when the yarns 14 are supplied to a plurality of (normally four) yarn feeders of the knitting machine, each yarn 14 is first fed to the tension device 10. Cymbal tension 1 on the top
3, then the outer peripheral surface of the upper tension roller (first tension roller) 6 is rotated once, and after passing through the intermediate guide 12, the lower tension roller (second tension roller) 6 ' Make a round of the outer peripheral surface. Then, the yarn 14 is supplied to an appropriate yarn feeder through the lower guide guide 15.

In this state, when the first tension roller 6 is rotationally driven and the second tension roller 6'is sub-rotated to perform knitting, the yarn 14 is a support type yarn having a strong compressive force. Yes, even though this is knitted at a low speed, the above two upper and lower tension roller 6,
Since the slip of the yarn 14 is regulated by 6 ', the tension on the yarn 14 is always constant, and a uniform knit stocking can be obtained.

In a normal knitting machine, the stitch length adjusting device is used to change the size of the stitches to change the lateral stretch of the fabric, so that an optimum fit can be obtained for each part such as the ankles, lower knees and thighs. The adjustment is made so that the yarn 14 can be adjusted by the above-described stitch adjusting device if the slip of the yarn 14 is restricted by the upper and lower tension rollers 6, 6'as in the present invention. Therefore, in the present invention, not only the special tension device 10 is provided, but the frequency control means (shown by the chain line 11 in FIG. 6) is connected to the frequency setter 8 (see FIG. 6) for setting the rotation speed of the motor 7. Then, the rotation speed of the tension rollers 6 and 6'is changed by changing the frequency of the frequency setting device 8. Thread 1
The feeding speed of No. 4 is changed and the tension of the yarn 14 is changed to change the lateral elongation of the obtained knitted fabric. Then, the change in the rotation speed is caused by the main body 2 of the knitting machine.
The movement of a racking pole (not shown) that operates in synchronization with the size control means built in the sensor is detected by the sensor of the frequency setting device 8 and the timing thereof is measured.

The stockings thus obtained are
By the frequency control means, the rotational speeds of the tension rollers 6 and 6'are changed and the tension of the yarn 14 is changed for each knitting portion, so that it fits to any portion of the foot and exhibits an excellent support force. Moreover, since the slippage of the thread 14 is regulated by the special tension device 10, in each portion knitted with the same tension,
The stitches are evenly arranged, and the quality is significantly superior to that of conventional computer patterned stockings.

The uniformity of the stitches can be evaluated as follows. That is, as shown in FIG. 3, the obtained fabric is stretched constantly in the vertical and horizontal directions to widen the stitches and enlarged by a microscope or the like, and the width A of each course is measured to calculate the mutual error. Then, the error is 10
When it is within the range of%, it can be said that it is the “state in which the stitches are aligned” of the invention.

Further, the tension device 10 used in the present invention
Is not limited to those shown in FIGS. 1 and 2, but may be any one as long as the yarn 14 is set so as to sequentially pass around the outer circumferences of the first and second tension rollers 6, 6 '. But it doesn't matter. For example, a pair of two tension rollers 6 and 6'may be arranged side by side or obliquely arranged. Alternatively, a plurality of two rollers or four rollers may be used and arranged as a pair of two tension rollers 6, 6 '. The means for introducing the yarn 14 into the first tension roller 6 may be other than the cymbal tension 13 as described above. Further, the means for feeding the yarn 14 from the second tension roller 6'is not limited to the guide guide 15 as described above, and any means may be used. In some cases, the cymbal tension 13 and the guide guide 15 may not be used.

Furthermore, in the above example, when the frequency of the frequency setting device is changed by the frequency control means, the timing is measured by sensing the movement of the racking pole operating in synchronization with the knitting machine. However, the sensing location does not necessarily have to be the racking pole, and may be any location that operates in synchronization with the count of the size control device of the knitting machine. Further, the timing may be sensed as an electric signal directly from the size control device.

Next, examples will be described.

[Table 2]

The patterned panty hose thus obtained had uniform stitches without horizontal stripes, and fit properly to any part of the foot. By the way, the foot part of this pantyhose,
An arbitrary part was picked up from each part of the leg part and the panty part, the course width A (see FIG. 3) was measured by the above-described method, and the error between them was calculated. The error was within 3 to 5%, and it was confirmed that the stitches were even.

[0027]

As described above, the patterned stocking of the present invention is knitted by changing the tension of the thread for each predetermined area according to the shape of the foot, so that it fits on any part of the foot. Shows excellent support. Moreover, by passing through the first and second tension rollers,
Since the yarn is supplied while the yarn slippage is regulated and the tension is evenly applied, the stitches are uniformly arranged in each part. Therefore, the fabric does not have horizontal stripes, and looks much better than the conventional computer patterned stocking.
