Description

Tubular knitting object and knitting method thereof

Technical Field

The present invention relates to a tubular knitted article and a knitting method thereof, and more particularly to a tubular knitted article and a knitting method thereof which are suitably used for socks, stockings, foot warming covers, arm warming covers, support covers (supporters), tights, stockings, and the like having such a tubular knitted article portion.

Background

In one example of the conventional technique that is the background of the present invention, a leg support cover is proposed in which the wearing pressure (tightening force) is set to a low pressure, a medium pressure, a high pressure, a medium pressure, and a low pressure from the ankle side. In the case of the leg support cover, the upper support cover tightens the calf in the vertical center portion thereof with a strong pressure, tightens the calf in both end portions thereof with a weak pressure, tightens the calf in the middle portion between the center portion and both end portions thereof with a medium pressure, and tightens the arch portion of the foot in the lower support cover with a strong pressure (for example, see patent document 1).

The leg support cover is formed by alternately arranging a band-shaped annular portion having a high tightening force and a band-shaped annular portion having a low tightening force in the vertical direction of the lower leg, and promotes blood circulation in the leg by utilizing muscular deformation of the calf portion during exercise.

In another example of the conventional art as a background of the present invention, a press-fit and swing stocking is proposed which is provided with a foot portion to be worn on a foot, a leg portion to be worn on a calf, and a welt rubber portion, wherein a press-fit region for applying pressure to the calf is provided between a lower end of the leg portion and a lower end of the welt rubber portion, and the leg portion is twisted outward or inward and worn on the calf, whereby the press-fit region applies pressure and a twisting force to the calf (for example, see patent document 2).

Problems to be solved by the invention

However, the leg support cover described in patent document 1 is a member that applies pressure in stages of low pressure, medium pressure, high pressure, medium pressure, and low pressure from the lower side of the calf (calf) to the upper side, and applies force in the direction orthogonal to the axis of the calf of the lower limb, so that only the muscle of the calf such as the triceps surae of the calf is compressed toward the axis. In this case, a strong tightening force acts on the entire circumference of the calf, and the calf is always tightly tightened toward the center of the leg. Therefore, the leg support cover has a restricted feeling in a worn state, and the expected effect of preventing or reducing edema cannot be obtained.

Further, although the legs and feet feel light when used for a predetermined period of time, if used for a long time, the blood circulation of the lower limbs may be inhibited, fatigue may be caused, or edema may be caused in the lower limbs. Therefore, it is not suitable as a leg support cover for long-term use such as jogging, hiking, and the like.

In the leg support brace described in patent document 1, the leg is knitted by the same knitting method in the course direction of the shin (calf) side on the front surface of the leg and the calf side on the rear surface, and the whole brace has a relatively strong tightening force, and is therefore difficult to wear.

On the other hand, the effect of applying pressure is questionable from the medical point of view, rather than applying pressure by locally giving a difference in strength to a site in a specific range (for example, calf side).

In the press-and-turn stockings to be worn disclosed in patent document 2, it takes time to wear the stockings, whether the leg is twisted 160 to 200 degrees, more preferably about 180 degrees, on the outer side and worn on the lower leg, or the leg is twisted after the stockings are worn, or the stockings are worn while the leg is twisted.

Accordingly, a primary object of the present invention is to provide a tubular knitted article and a knitting method thereof, which can be worn without taking time and effort, can provide a good fit to the entire wearing portion without causing a wearer to feel any restraint, and can prevent or reduce edema even after long-term use.

Detailed Description

Fig. 1 (a) is a front view illustrating an example of the tubular knitted article of the present invention. Fig. 2 is a perspective view schematically showing the form of the tubular knitted object shown in fig. 1 (a). The knitted fabric 10 has a cylindrical shape, but is illustrated in a cylindrical shape for convenience in fig. 2.

As shown in fig. 2, the tubular knitted object 10 includes a tubular knitted fabric main body 12. As shown in fig. 1 (a) and 2, the knitted fabric main body 12 is provided with a first knitted part 14, and the first knitted part 14 extends in a direction inclined with respect to the axial direction of the knitted fabric main body 12 and is knitted spirally in the circumferential direction of the knitted fabric main body 12. Further, the second knitted fabric portion 16 is disposed adjacent to the first knitted fabric portion 14 in the knitted fabric main body 12. The second knitted fabric portion 16 extends in a direction inclined with respect to the axial direction of the knitted fabric main body 12, and is knitted spirally in the circumferential direction of the knitted fabric main body 12, similarly to the first knitted fabric portion 14.

In an example of a mode for carrying out the present invention, as shown in fig. 2, the first knitting unit 14 and the second knitting unit 16 are knitted by stitches 18 of knitting yarns, and particularly, as shown in fig. 3, for example, are knitted by a plain knitting method.

As shown in fig. 2 and 3, an elastic yarn 20 is knitted into the second knitted fabric portion 16 of one of the first knitted fabric portion 14 and the second knitted fabric portion 16. As shown in fig. 3, the elastic yarn 20 is knitted into the stitches 18 by tucking appropriately from one end side to the other end side in the course direction, or the stitches 18 may be looped by the elastic yarn 20. Note that, in fig. 2, the elastic yarn 20 is shown by a thick line for convenience in order to facilitate understanding of the position where the elastic yarn 20 is knitted, but in fig. 3, the form in which the elastic yarn 20 is knitted by being appropriately tucked is shown by a thick line.

When the elastic yarn 20 is tucked into the stitches 18, the elastic yarn 20 may be tucked into all courses of the second knitted fabric portion 16 and the elastic yarn 20 may be knitted, or the elastic yarn 20 may be tucked every 1 course in the course of the second knitted fabric portion 16 and the elastic yarn 20 may be knitted.

In this case, as shown in fig. 3, in particular, the elastic yarn 20 may be inserted in the first course (1 st course) to perform tucking, the elastic yarn 20 may not be inserted in the next course (2 nd course), and the elastic yarn 20 may be inserted in the next course (3 rd course) to perform tucking, and the following steps may be repeated in this order.

The tubular knitted article 10 shown in fig. 1 (a) has a mouth portion 24 and a mouth portion 26 at one end and the other end in the axial direction, respectively, and the

mouth portions

24 and 26 have substantially the same diameter.

Fig. 1 (B) is a front view showing another example of the tubular knitted article of the present invention. In the tubular knitted article 10, in particular, the diameter of one mouth portion 28 is formed larger than the diameter of the other mouth portion 30, as compared with the tubular knitted article 10 shown in fig. 1 (a). That is, the width of the first knitted fabric portion 14 in the course direction is knitted to be wider near one end side (upper end side) in the axial direction of the knitted fabric object 10 and narrower near the other end side (lower end side) in the axial direction. In the tubular knitted fabric 10 shown in fig. 1 (B), the length of the knitted fabric main body 10 in the course direction can be gradually narrowed by gradually decreasing the number of stitches 18, that is, so-called narrowing, from the side of one mouth portion 28 to the side of the other mouth portion 30. Further, the length of the knitted fabric main body 10 in the course direction may be gradually narrowed by gradually decreasing the size (stitch density) of the stitches 18 from the side of the mouth portion 28 on one side of the knitted fabric body 10 to the side of the mouth portion 30 on the other side.

In addition, (C) of fig. 1 is a front view illustrating a comparative example. The tubular knitted object 1 includes a knitted fabric main body 1a, and the knitted fabric main body 1a does not have the first knitted fabric portion 14 and the second knitted fabric portion 16 knitted in a spiral shape, as compared with the tubular knitted object 10 in fig. 1 (a) and (B). In this case, on one surface (one main surface side) of the tubular knitted fabric main body 1a, a knitted part 3 extending in a direction orthogonal to the axial direction of the tubular knitted fabric main body 1a and surrounding in a tubular shape in the circumferential direction of the knitted fabric main body 1a is knitted. In the knitting portion 3, an elastic yarn (not shown) is inserted or knitted into one surface of the knitting object 3.

Fig. 4 is a perspective view schematically showing a modification of the tubular knitted object shown in fig. 1 (a) and 2. This tubular knitted article 10 is different from the tubular knitted article 10 shown in fig. 1 (a) in that an elastic yarn 20 is knitted in the first knitted part 14 in addition to the second knitted part 16 in particular. In this case, the elastic yarn 20 may be knitted by, for example, appropriately tucking the stitches 18 from one end side to the other end side in the course direction, or the stitches 18 may be knitted with the elastic yarn 20, as in the tubular knitted object 10 shown in fig. 1 (a).

In the tubular knitted object 10 shown in fig. 1 (a), 1 (B), 2, and 4, the first knitted part 14 and the second knitted part 16 having a spiral form extend in the same direction and are knitted in a direction inclined with respect to the axial direction of the knitted fabric main body 12, but the first knitted part 14 and the second knitted part 16 may extend in a direction opposite to each other and are knitted in a direction inclined with respect to the axial direction of the knitted fabric main body 12.

In addition, "wraparound" in the drawings of fig. 9 to 29 represents a case where the first knitted fabric portion 14 and the second knitted fabric portion 16 described above are knitted in the tubular knitted object 10 instead.

In the tubular knitted article 10 shown in fig. 1 (a), 1 (B), 2, and 4, the knitted fabric structure is knitted from a non-patterned knitted fabric structure having no pattern by, for example, plain knitting, but in addition to this, various knitted fabric structures (knitting structures) can be changed by combining various patterns or elastic yarns as shown in, for example, fig. 9 to 29.

That is, in the tubular knitted article 10 shown in fig. 9, one side (front surface) thereof is a rubber tuck, and the other side (rear surface) thereof is knitted in a looped manner.

In the tubular knitted article 10 shown in fig. 10, one side (front surface) is a rubber tuck having a JQ (jacquard) pattern of stripes (vertical stripes), and the other side (rear surface) is knitted in a loop.

The outline of the knitting method of the tubular knitted article 10 (see fig. 30) is that, for example, in a weft knitting machine, knitting is performed on a pair of front and rear needle beds,

(1) By inserting or knitting an elastic yarn (e.g., a rubber thread) into the elastic yarn, and at the same time,

(2) First, every time the stitches at the front and rear ends are knitted in the course 1, the front side stitch is moved to the rear side stitch, the rear side stitch is moved to the front side stitch, and the knitting is repeated,

(3) Then, every time knitting 1 course of the stitches at both front and rear ends, the front side stitch is moved to the rear side stitch, the rear side stitch is moved to the front side stitch, and the knitting is repeated,

basically, the second knitted fabric portion 16 of the tubular knitted object 10 shown in fig. 1 (a), 2, and 3 can be knitted by repeating the steps (1), (2), and (3).

At this time, in the step (2), when the transfer start of the pair of front and rear needle beds is the left end, the rotation direction of the object to be knitted 10 is clockwise, and in the step (3), when the transfer start of the pair of front and rear needle beds is the right end, the rotation direction of the object to be knitted 10 is counterclockwise.

That is, if the knitting process is described in detail in the following steps with reference to fig. 30, the knitting process includes: (step 1) after the yarn carrier No.2 to yarn carrier No.1 are left-hand moved in the carriage traveling direction, the yarn is looped. In this case, the yarn carrier nos. 2 to 1 are moved to the right in the carriage traveling direction without needle selection. Then, the carrier nos. 2 to 1 are left-hand moved in the carriage traveling direction and then looped.

(step 2) the yarn carrier Nos. 4 to 3 are left-hand moved in the carriage traveling direction to carry out front knitting. In this case, the yarn carrier nos. 4 to 3 are caused to travel rightward in the carriage traveling direction for front loop formation. Then, the carrier nos. 4 to 3 are moved leftward in the carriage traveling direction without needle selection.

(step 3) the stitches are held on the knitting needle slider of the front needle bed opposed to the knitting needles of the back needle bed.

(step 4) the back needle bed is shifted leftward by 1 pitch, the stitches held on the slider of the knitting needle of the front needle bed are returned to the knitting needle of the back needle bed, and the back needle bed is shifted rightward by 1 pitch. In this case, the needle selection preparation process is performed only by the movement of the carriage. Then, the yarn carrier nos. 4 to 3 are made to travel rightward in the carriage traveling direction, and only the yarn carrier is made to move rightward.

(step 5) the left end (1) needle of the knitting needle of the front needle bed is transferred from the front needle bed to the needle opposite to the back needle bed. In this case, the yarn carriers No.4 to No.3 are moved in the left direction without needle selection in the carriage traveling direction.

(step 6) the stitches are held on the knitting needle slider of the back needle bed opposed to the knitting needles of the front needle bed.

(step 7) the back needle bed is shifted leftward by 1 pitch, the stitches held on the slider of the knitting needle of the back needle bed are returned to the knitting needle of the front needle bed, and the back needle bed is shifted rightward by 1 pitch.

(step 8) the right end (1) needle of the knitting needle of the back needle bed is transferred from the back needle bed to the opposite needle of the front needle bed.

(step 9) the yarn carrier No.5 tucks and inserts an elastic yarn (for example, a rubber thread) into the knitting needle of the back needle bed. In this case, the loop formation may be performed.

(step 10) the yarn carrier No.5 inserts the tuck of the elastic yarn into the knitting needle of the front needle bed. In this case, the loop formation may be performed.

(step 11) the yarn carrier Nos. 2 to 1 are moved rightward in the carriage traveling direction, and then stitch is formed. In this case, the carrier nos. 2 to 1 are left-hand-moved in the carriage traveling direction and then looped. Then, the carrier nos. 2 to 1 are moved to the right in the carriage traveling direction without needle selection.

(step 12) the yarn carrier Nos. 4 to 3 are moved rightward in the carriage traveling direction to perform front loop formation. In this case, the yarn carriers No.4 to No.3 are moved in the left direction without needle selection in the carriage traveling direction. Then, the yarn carrier nos. 4 to 3 are moved rightward in the carriage traveling direction to perform front knitting.

(step 13) the stitches are held on the knitting needle slider of the front needle bed opposed to the knitting needles of the back needle bed.

(step 14) the back needle bed is shifted leftward by 1 pitch, the stitches held on the slider of the knitting needle of the front needle bed are returned to the knitting needle of the back needle bed, and the back needle bed is shifted rightward by 1 pitch. In this case, the needle selection preparation process is performed only by moving the carriage. In this case, the stitches of the left end (1 needle) of the front needle bed knitting needle are spread by the float selection (the operation of only the sinking).

(step 15) the left end needle (1) of the front needle bed knitting needle is transferred from the front needle bed to the opposite needle of the back needle bed.

(step 16) the loop is held on the knitting needle slider of the back needle bed opposed to the knitting needle of the front needle bed.

(step 17) the back needle bed is shifted leftward by 1 pitch, the stitches held on the slider of the knitting needle of the back needle bed are returned to the knitting needle of the front needle bed, and the back needle bed is shifted rightward by 1 pitch.

(step 18) the right end needle (1) of the knitting needle of the back needle bed is transferred from the back needle bed to the opposite needle of the front needle bed.

(step 19) the yarn carrier No.5 inserts the tuck of the elastic yarn into the knitting needle of the back needle bed. In this case, the loop formation may be performed.

(step 20) the yarn carrier No.5 inserts the tuck of the elastic yarn into the knitting needle of the front needle bed. In this case, the loop formation may be performed.

In

steps

4, 7, 14, and 17 of the knitting process, the winding-in is performed at 1 pitch in the case of the tight stitch, and at 2 pitches in the case of the draw stitch.

Fig. 31 is an explanatory diagram showing an example of a measuring method for measuring the wearing pressure of a tubular knitted object of the present invention, the upper column of fig. 31 is an explanatory diagram showing a measurement site of the tubular knitted object to be measured, and the lower column of fig. 31 is an explanatory diagram showing an example of a workpiece on which the tubular knitted object is worn and showing a state in which a measuring instrument is attached to a position (measurement site) corresponding to the measurement site of the tubular knitted object. The tubular knitted object shown in the upper column of fig. 31 shows a state in which the tubular knitted object 10 shown in fig. 9 is worn on a workpiece shown in the lower column of fig. 31, for example.

Therefore, an example of a measuring method for measuring the wearing pressure of the tubular knitted object of the present invention will be briefly described below. In this case, the wearing pressure indicates a tightening force of the tubular knitted fabric 10 applied by contacting a specific body part when the tubular knitted fabric 10 is worn.

First, as a measuring device, for example, a contact pressure measuring instrument (product number AMI 3037-10) manufactured by AMI techon co.

Next, as shown in the lower column of fig. 31, the measurement device is constituted by an air bag (pressure receiving sensor) constituted by a bag and a tube, an air cylinder provided with a piston valve and an exhaust hole, and a pressure measuring instrument with a display portion incorporating a pressure sensor for measuring a pressure difference with the atmosphere.

In this measuring apparatus, the pressure measuring device including one pressure sensor measures that the pipe of the pressure sensor placed at a position is connected to the connection portion, the relay pipe is connected to the connection port, the cock is pulled out, the air sealing operation is performed, and the measured value (pressure value) is displayed on the display portion. In this measuring apparatus, the tube of each air bag (pressure sensor) attached to the measurement site is connected to the connecting portion of the pressure measuring instrument, and the measurement operation is repeated, whereby multi-point measurement can be performed. In addition, reference numerals are omitted for the measurement device and its respective instruments shown in fig. 31.

As a measurement method, for example, a device is prepared in which airbags (pressure sensors) each composed of a bag and a tube are attached to each of 8 measurement sites a, B, C, D, E, F, G, and H of a workpiece (for example, a vinyl chloride tube) regarded as a simulated living body, and a tubular knitted object 10 shown in fig. 9, for example, is worn on the workpiece.

Then, the pressure values at the respective 8 measurement portions a, B, C, D, E, F, G, and H of the tubular knitted object 10 corresponding to the respective 8 measurement portions a, B, C, D, E, F, G, and H are measured by the measurement device. Similarly, the pressure values at the measurement portions a, B, C, D, E, F, G, and H of the tubular knitted object 10 shown in fig. 10 to 29 are measured.

Fig. 32 is an explanatory view showing a table of measurement results of the wearing pressure (pressure value) of the tubular knitted articles of samples nos. 1 to 12 shown in fig. 9 to 20. Fig. 33 is an explanatory view showing another table of measurement results of the wearing pressures (pressure values) of the tubular knitted articles of samples nos. 1 to 12 shown in fig. 9 to 20. Fig. 34 (a) is an explanatory view showing a table of measurement results of the wearing pressures (pressure values) of the tubular knitted articles of samples nos. 13 to 15 shown in fig. 21 to 23, and fig. 34 (B) is an explanatory view showing another table of measurement results of the wearing pressures (pressure values) of the tubular knitted articles of samples nos. 13 to 15 shown in fig. 21 to 23. Fig. 35 (a) is an explanatory view showing a table of measurement results of the wearing pressures (pressure values) of the tubular knitted articles of samples nos. 16 to 18 shown in fig. 24 to 26, and fig. 35 (B) is an explanatory view showing another table of measurement results of the wearing pressures (pressure values) of the tubular knitted articles of samples nos. 16 to 18 shown in fig. 24 to 26. Fig. 36 is an explanatory view showing a table of measurement results of the wearing pressure (pressure value) of the tubular knitted articles of samples nos. 19 to 21 shown in fig. 27 to 29.

The "wraparound" in the tables of fig. 32 to 37 represents, instead, a case where the first knitted fabric portion 14 and the second knitted fabric portion 16 described above are knitted in the tubular knitted object 10 from the viewpoint of the structure, and represents, instead, a knitting step of performing the above-described

steps

4, 5, 7, 8, 17, 18 and the like from the viewpoint of the knitting method.

In more detail:

the stitch looping refers to a knitting fabric knitted in a tubular shape or a tubular shape having a substantially C-shaped cross section with the front and rear needle beds, in which a stitch located at one of the left and right side ends among stitches located on one needle bed is moved to the outside of the side of the stitch located at the one of the left and right side ends among stitches located on the opposite needle bed, that is, the knitting fabric is rotated on the needle beds. As a specific method of the stitch looping, for example, when the same number of stitches are held in the needles of the front needle bed and the rear needle bed so as to face each other, the rear needle bed is, for example, laterally moved in the right direction, and the stitches held in the needles of the front and rear needle beds are arranged so as to be shifted in position in the right-left direction. At this time, the needle of the front needle bed facing the stitch of the right end of the rear needle bed has no stitch, and the needle of the rear needle bed facing the stitch of the left end of the front needle bed has no stitch. Therefore, the knitted fabric is, for example, rotated clockwise by transferring the stitches of the side end shifted in position to the empty needles of the opposing needle bed.

The following shows the examination of the measurement results of fig. 32 and 33 and the examination results.

< examination >

The pressure values (wearing pressures) were higher in the cases with wraparound than in the cases without wraparound, respectively, in samples nos. 1 to 12.

When the case of the sample No.1 with the wraparound and the case of the sample No.4 with the wraparound were compared, the pressure value (wearing pressure) of the loop formation was slightly increased as compared with the tuck.

In samples No.1 and No.4, the difference in pressure values (difference in wearing pressure) between the region where the rubber thread is inserted and the region where the rubber thread is not inserted is increased. At this time, the difference in pressure value (difference in wearing pressure) of sample No.4 is larger.

In the case of the presence or absence of the wraparound of the samples No.7 and No.10, the pressure value (dressing pressure) was not greatly different depending on the presence or absence of the wraparound.

When sample No.1 and sample No.7 are compared, the overall pressure value (wearing pressure) is higher in sample No.7, but the difference between the pressure values (difference between wearing pressures) is larger in sample No. 1.

In samples nos. 1 to 3 and 7 to 9, the pressure value (wearing pressure) was larger when the rubber thread was knitted on the entire surface than when the rubber thread was knitted only on one surface, regardless of the presence or absence of the winding and the difference in the face yarn structure.

In the case of the samples nos. 1 to 3 and 4 to 6, when the wraparound is present, the pressure value (wearing pressure) of the JQ becomes small in the case of the loop formation, and becomes large in the case of the tuck.

The difference in pressure values (difference in wearing pressure) across the surface was small between samples 1 to 6 and samples 7 to 12.

The difference in pressure values (difference in wearing pressure) between samples No.1 to No.6 and samples No.7 to No.12 is larger when wound than when not wound. That is, the difference in pressure values (difference in wearing pressure) is significantly increased in the case where the wraparound occurs as compared with the case where the wraparound does not occur.

In samples nos. 1 to 3 and 4 to 6, the pressure value of the opposite surface tends to be lower in the case where the rubber thread is inserted (rubber tucked) on one surface and the rubber thread is not wound than in the case where the rubber thread is not inserted and the rubber thread is not wound.

< examination results >

By winding in, the partial pressure value (wearing pressure) increases.

When the area (wearing pressure area) where the rubber thread is inserted or tucked is located on one surface, the difference between the pressure values is larger, and an effective pressure value (wearing pressure) is exerted.

In samples No.1 to sample No.12, the pressure value (wearing pressure) tends to be stronger in the case of loop formation as a whole than in the case of tuck, but the difference in pressure value (difference in wearing pressure) is more effective in the case of tuck.

The effective pressure values (wearing pressures) were considered to be exerted by sample Nos. 1, 4 and 6.

Based on the examination and examination results of the measurement results of fig. 32 and 33, the pressure value (wearing pressure) of the region (wearing pressure region) where the rubber thread is inserted or tucked is increased by winding the region (wearing pressure region) where the rubber thread is inserted or tucked on one side.

Here, in the measurement results of fig. 32 and 33, particularly, when the measurement results of sample No.1, sample No.4, sample No.7, and sample No.10 were extracted and examined, in the case of comparing the presence or absence of the wraparound of the one-side rubber tuck of sample No.1, the pressure value of the region (wearing pressure region) into which the rubber thread is inserted is higher in the case of the wraparound. In addition, in the case of comparing the presence or absence of the wraparound of the single-sided rubber loop of sample No.4, the pressure value of the area (wearing pressure area) where the rubber loop was tucked was higher in the case of the presence of the wraparound. In addition, in the case of comparing the presence or absence of the wraparound of the entire surface rubber tuck of sample No.7, the presence or absence of the wraparound does not cause a large difference in the pressure value (wearing pressure). In addition, in the case of the comparison sample No.10, in which the presence or absence of the wraparound of the entire-surface rubber loop does not cause a large difference in the pressure value (wearing pressure) depending on the presence or absence of the wraparound.

That is, the pressure value of the rubber thread insertion portion having the wraparound is higher with respect to the presence or absence of the wraparound. In addition, in the case where the winding-in is not performed, the pressure value of the opposing face portion is higher than that of the rubber wire insertion portion. In addition, when the rubber thread is inserted over the entire surface, the pressure value (wearing pressure) of the entire tubular knitted object becomes high, but the difference in pressure value (difference in wearing pressure) becomes small.

In particular, in the case of one-sided rubber tucking in which a rubber thread is inserted on one side or in the case of one-sided rubber looping in which a rubber thread is knitted on one side, the difference between the pressure value (putting-on pressure) of the rubber thread insertion portion caused by winding and the pressure value of the portion (portion on the opposite surface) in which the rubber thread is not inserted caused by winding can be increased.

In the tubular knitted article 10 used for carrying out the embodiment of the present invention, when the knitted article 10 is worn on a specific part of an upper limb or a lower limb, a wearing pressure difference can be applied to the specific part by the above-described wraparound and knitting of the elastic yarn. In this case, it is considered that blood flow in the deep part of the muscle is promoted at the part where the tubular knitted article 10 is worn, blood circulation is promoted, and relaxation of edema and laziness is promoted. Therefore, the tubular knitted fabric 10 having excellent effects of reducing the body fit, wearing pressure comfort, swelling, and fatigue feeling when worn, and the like can be obtained.

The knitting structure of the tubular knitted article 10 used in the embodiment of the present invention is not particularly limited, and a pattern may be knitted by knitting a stitch, tuck, stitch of a stretch hole, or a combination thereof.
