Description

The present invention relates to a sock, a foot cover, a supporter such as an elbow / knee / calf, an arm cover, a tubular textile product such as a soccer stocking, and more specifically, a tubular textile product having a non-slip function.

In tubular textile products such as socks and supporters that can be worn from the thin part to the thick part of the body, the part corresponding to the thick part slips, shifts, or swells easily toward the thin part. For example, even if you wear socks and pull the upper end up from the ankle, the upper end will shift downward due to gravity or fiber contraction, or will be lifted by the movement of the ankle joint when walking or running. In addition, if it is a knee supporter, by bending and stretching the knee, it will come from the thick part of the thigh or lower leg toward the knee.

In order to alleviate or prevent such slippage and sagging of tubular textile products, anti-slip liquid or glue is applied to the inside of the opening or through-hole of the textile product when worn, or anti-slip resin is applied in the final process. It has been practiced to attach and knit non-slip threads. As an example of using a non-slip yarn, for example, Patent Document 1 proposes a knee joint supporter provided with a tightening portion for preventing vertical slippage by inserting a polyurethane elastic yarn and knitting it with an inlay knitting. ing.

However, anti-slip liquids and glues may affect the skin such as rashes. In addition, the spots where the anti-slip liquid is applied remain in dots, which adversely affects the original function and fashionability. The method of attaching the non-slip resin in the final process is costly due to the increased number of processes, and since the non-slip resin is attached to the knitted fabric later, distortion and misalignment occur, the quality is not stable, and several times. It may come off when worn or washed. In order to improve the adhesion to the skin, the non-slip yarn contains a large amount of expensive yarn with a high coefficient of friction such as polyurethane yarn such as Downstop (registered trademark), silicon yarn, and fine polyester yarn such as Nanofront (registered trademark). Must be used for, making the product expensive.

Patent No. 4964443

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a tubular knitted fiber product having a high anti-slip effect, an inexpensive price, and good fashionability.

As a means for solving the above-mentioned problems, the present invention is woven with a thread having a higher coefficient of friction than other adjacent knitted fabrics at a portion in contact with the non-slip target portion toward the non-slip target portion. A plurality of protruding parts are woven.

In the present invention, the plurality of protrusions woven with the yarn having a high coefficient of friction come into contact with the non-slip target portion, so that the high friction yarns of the plurality of protrusions come into contact with each other so as to be pressed against the non-slip target portion. High anti-slip effect.

The protruding portion is woven with a large degree as compared with other knitted fabrics adjacent in the course direction or the wale direction.
In the present invention, since the protrusion has a large degree, the protrusion fits into the anti-slip target surface, and the anti-slip effect is enhanced.

The protrusion has less elasticity than the adjacent knitted fabric.
In the present invention, since the protrusion has low elasticity and does not expand or contract, the protrusion sticks to the anti-slip target surface, and the anti-slip effect is enhanced.

The protruding portion may be woven by a float knitting. In the present invention, the knitted portion formed by the high friction yarns on both sides of the floated knitting yarn is raised to become a protruding portion.

The knitting yarn floated in the float knitting is provided on the side in contact with the non-slip target portion. In the present invention, the floated knitting yarn also functions as a non-slip together with the stitches.

The protruding portion may be woven by tuck knitting. In the present invention, the knitted portion formed by the high friction yarn on both sides of the tacked knitted yarn is raised to become a protruding portion.

The protruding portion is woven by an insertion knitting in which a rubber thread is inserted, and the rubber thread is woven by adjusting the insertion interval.
In the present invention, due to the contraction of the rubber thread on the back side straddling between the rubber thread insertion portions, the knitted portion by the high friction yarn corresponding to the rubber yarn straddling between the rubber thread insertion portions rises and becomes a protruding portion. .. The area of the protrusion can be changed by adjusting the insertion interval of the rubber threads.

The protruding portion is woven into the knitted fabric in contact with the non-slip target portion of the folded portion of the knitted fabric.
In the present invention, the high friction yarn is raised on the front surface of the knitted fabric of the folded portion and the protruding portion is woven, but by folding the folded portion, it comes into contact with the non-slip target portion.

According to the present invention, a plurality of protrusions woven with threads having a high coefficient of friction come into contact with the non-slip target portion, so that the high friction threads of the plurality of protrusions come into contact with each other so as to be pressed against the non-slip target portion. Therefore, the anti-slip effect is high.

Further, since it has a plurality of protrusions woven with a yarn having a high friction coefficient, it can be manufactured at a lower cost than knitting a high friction yarn on the entire surface.

Furthermore, the plurality of protrusions are woven with a thread having a high coefficient of friction and are knitted in the same manner as the adjacent knitting parts, so that there is no discomfort like an anti-slip agent and the anti-slip resin is peeled off. There is no fear, and fashionability is improved by arranging a plurality of protrusions regularly.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a sock 1 which is an example of a tubular knitted fiber product according to the present invention. The sock 1 is composed of a leg portion 2, a heel portion 3, a foot portion 4, and a toe portion 5. At the upper end of the leg portion 2, a cuff 2c is knitted by a folded inner portion 2a and a folded outer portion 2b. In the folded-back inner portion 2a, a plurality of substantially rectangular projecting portions 6 projecting toward the surface of the lower limbs of the person wearing the sock 1, that is, the non-slip target portion, are arranged in a plurality of rows (4 rows in the embodiment) at regular intervals in the course direction. It is woven with.

As shown in FIG. 2, the plurality of protrusions 6 in the row adjacent to the wale direction W are arranged in the Kanoko with a deviation in the course direction C. That is, the center of the protrusion 6 of the adjacent row is located on the line of the wale direction W between the protrusions 6 arranged in the course direction C of a certain row. When the protrusions 6 are in four rows, the distance between the protrusions 6 in the first row and two rows and the protrusions 6 in the next three rows and four examples in the wale direction W is one row and two rows. It is arranged wider than the interval of the wale direction W between the three rows and the interval of the wale direction W between the third row and the fourth row.

The protruding portion 6 is woven with a yarn having a higher coefficient of friction than the ground yarn of the knitted fabric adjacent to the wale direction W to perform a non-slip function. As the ground yarn, a yarn obtained by aligning a natural fiber such as cotton or a synthetic fiber such as polyester with a back yarn such as spandex (or a yarn using a rubber insertion knit) or the like can be used. On the other hand, as the yarn having a high coefficient of friction, a high friction yarn such as a polyurethane yarn such as Downstop (registered trademark), a silicon yarn, and a fine polyester yarn such as Nanofront (registered trademark) can be used. .. By knitting the protruding portion 6 with the high friction yarn, the high friction yarn comes into contact with the non-slip target surface so as to be pressed against the surface, so that the protrusion 6 becomes hard to slip.

The protruding portion 6 is woven with a large degree of stitches as compared with the stitches of other knitted fabrics that are separated and contacted in the wale direction. Since the protrusion 6 has a large degree, the protrusion 6 becomes familiar with the non-slip target surface of a person, and the anti-slip effect is enhanced.

As shown in FIG. 3, the degree of adjustment is such that the sinker 23 and the hook 24 of the lowered needle 22 are adjusted by moving the cylinder 20 of the circular knitting machine up and down or changing the degree of pulling down of the needle 22 by the degree mountain 21. This can be done by changing the size of the loop of the stitch by changing the dimension h between the stitches.

The protrusion 6 has less elasticity than other adjacent knitted fabrics. That is, while the other adjacent knitted fabrics use spandex for the back yarn, the protruding portion 6 does not use the back yarn spandex, so that the elasticity is small. Since the protrusion 6 has low elasticity and does not expand or contract, the protrusion 6 sticks to the non-slip target surface of a person, and the anti-slip effect is enhanced.

FIG. 4 shows the knitting structure of the protruding portion 6 by the float knitting seen from the back side. In FIG. 4, a normal knitted portion is knitted from the lower part to the course A1 by the ground yarn 7 (rubber insertion knitting using the back yarn spandex). From the course a, the stitches are made larger than the stitches of the normal knitting portion, and the yarn is switched to the high friction yarn 8 (without back yarn spandex). In stitch B1, skip without making stitches and knit the next stitches 1 to 9 stitches. In the stitch B2 after the ninth stitch, as in the stitch B1, the stitch is skipped without making a stitch, nine stitches are knitted, and this is repeated as appropriate to complete one course.

This is repeated for 7 courses from a to g, the degree is returned to the normal degree in the course A2, the yarn is switched to the ground yarn 7, and the normal knitted portion is knitted. Here, in the stitches B1 and B2, the stitches held by the needles in the course A1 are entwined with the stitches of A2 to form the stitches. As a result, the stitches 1 to 9 of the 7 courses from a to g are pulled by the stitches of the courses A1 to A2 in the stitches B1 and B1, and the stitches are lifted to the front side in the wale direction. In addition, since the fabric shrinks in courses A1 and A2 due to the rubber insertion knitting using the back thread spandex up to course A1 and after course A2, the stitches 1 to 9 of the 7 courses from a to g also float in the course direction. .. As a result, the rectangular region surrounded by the stitches 1 to 9 and the stitches a to g is knitted as a protruding portion 6 protruding from the adjacent normal knitting portion.

FIG. 5A is a simplified view of the knitting structure of the float knitting of FIG. 4, that is, the loop of the knitting structure of the float knitting of FIG. 4 is shown by a circular line, and the floated yarn (crossing yarn) is shown by a horizontal line. Shown, the ground thread is shown by a thin line, and the high friction thread is shown by a thick line.
FIG. 5B is a knitting structure of a modified example of the float knitting shown in FIG. 5A, in which the floating position is shifted by one stitch every two courses. In this case, the protruding portion 6 has a parallel four-sided shape, and no gaps (B1 and B2 in FIG. 4) are formed in the course direction, so that the anti-slip effect is enhanced.
In this way, the shape of the protrusion 6 can be changed by changing the floating position.

FIG. 6 is a developed view showing the knitting structure of the sock 1. The sock 1 is knitted from the leg 2 toward the toe 5 by a circular knitting machine.

First, the leg portion 2 is knitted into a cylindrical shape from the folded inner portion 2a by normal rotation knitting. Four rows of protruding portions are knitted on the folded inner portion 2a of the leg portion 2. After the folded inner portion 2a, the folded outer portion 2b is knitted. When the outer portion 2b is knitted, the knitting start end of the folded inner portion 2a is connected to the knitting end. Following the folded outer portion 2b, the entire leg portion 2 is knitted. Following the leg portion 2, the heel portion 3 is knitted into a bag shape by forward / reverse inversion knitting. After knitting the heel portion 3, the foot portion 4 is knitted into a cylindrical shape by forward knitting. Following the foot part 4, the toe part 5 is continuously knitted in a forward / reverse reverse knitting. The sock 1 is formed by joining the knitting end of the toe portion 5 and the knitting end of the foot portion 4.

FIG. 7 shows an actual tubular knitted fiber product in which the protruding portion 6 is knitted on the folded inner portion 2a. High friction yarns are raised on the front surface of the knitted fabric and the protruding portion 6 is woven into the folded inner portion 2a, but by folding the folded inner portion 2a inward, it comes into contact with the non-slip target portion. Since the protruding portion 6 is on the front surface of the knitted fabric, the appearance is beautiful and the functional fashionability expressing the function is improved.

FIG. 8 is a modification of the sock 1 of FIG. 1, in which the cuff 2c of the leg 2 is not folded inward, and the inside of the cuff 2a of the leg 2, that is, the non-slip target portion of a person. The protrusion 6 is knitted on the side that comes into contact with.

In this case, as shown in FIG. 9, two float knits that float one stitch for one stitch are performed, three courses of normal stitches are knitted, and then one stitch is floated for one stitch. By performing the float knitting on two courses, the stitches of the high friction yarns of the first two courses and the latter two courses and the floated yarns are raised on the back side, so that the elongated two rows of protruding portions 6 are on the back side, that is, the cuffs 2c. Protrudes inward.

The protruding portion 6 can be knitted by a tack knitting or an insertion knitting in addition to the float knitting shown in FIG.

FIG. 10 shows the knitting structure of the protruding portion 6 by the tack knitting seen from the back side. In FIG. 10, after knitting a normal knitted portion with a ground yarn 7 (rubber insertion knitting using back thread spandex) from the lower part to the course A1, the degree is larger than the degree of the normal knitted portion from the course a. Then, switch to high friction yarn 8 (without back yarn spandex). In the stitch B1, the stitch is held on the needle without making a stitch, and nine stitches are knitted from the next stitch 1 which is the start of the protrusion 6. In the stitch B2 after the ninth stitch, as in the stitch B1, the stitch is held on the needle without making a stitch, nine stitches are knitted in sequence, and this is repeated as appropriate to complete one course.

This is repeated for 7 courses from a to g, the stitches are returned to the normal stitches in the course A2, and the stitches are switched to the ground thread 7 to knit the normal knitted portion. Here, in the stitches B1 and B2, the high friction yarn 8 held on the needle without forming a stitch from the courses a to g is put together together with the ground yarn 7 of the courses A1 and A2 to form a stitch. As a result, the stitches 1 to 9 of the 7 courses from a to g are pulled by the tacks of the stitches B1 and B2, and the stitches are lifted to the front side in the wale direction. As a result, the region surrounded by the stitches 1 to 9 and the stitches a to g is knitted as a protruding portion 6 protruding from the adjacent normal knitted portion.

FIG. 11 shows the knitting structure of the protruding portion 6 by the insertion knitting seen from the back side. In FIG. 4, after knitting a normal knitted portion with a ground yarn 7 (rubber insertion knitting using back thread spandex) from the lower part to the course A1, the degree is larger than the degree of the normal knitted portion from the course a. Then, while switching to the high friction thread 8 (without back thread spandex), the rubber thread 9 is inserted. At the stitch B1 which is the start of the protrusion 6, the rubber thread 9 is knitted by insert knitting, and when the stitch B1 is passed, the rubber thread 9 is skipped to the back side without knitting, and nine stitches are knitted. In the stitch B2 after the ninth stitch, the rubber thread 9 is knitted by insert knitting in the same manner as the stitch B1, and then the nine stitches are knitted in sequence, and this is repeated as appropriate to complete one course.

This is repeated for 7 courses from a to g, the number is returned to the normal degree in course A2, and the yarn is switched to the ground yarn 7 (rubber insertion knitting using back thread spandex) to knit the normal knitted portion. As a result, the stitches 1 to 9 of the 7 courses from a to g are pulled by the contraction of the rubber thread 9 on the back side, the stitches rise to the front side in the course direction, and the stitches sink in the stitches B1 and B2. In addition, since the fabric shrinks in courses A1 and A2 due to the rubber insertion knitting using the back thread spandex up to course A1 and after course A2, the stitches 1 to 9 of the 7 courses from a to g are also in the course direction. Float. In addition, since the fabric shrinks in courses A1 and A2 due to the rubber insertion knitting using the back thread spandex up to course A1 and after course A2, the stitches 1 to 9 of the 7 courses from a to g also float in the course direction. .. As a result, the rectangular region surrounded by the stitches 1 to 9 and the stitches a to g is knitted as a protruding portion 6 protruding from the adjacent normal knitting portion.

In FIG. 11, the protruding portion 6 of the 9 × 7 stitch is knitted, but the region of the protruding portion 6 can be increased by adjusting the interval of the rubber threads 9 knitted on the front side (insertion interval of the rubber threads). It can be made smaller and changed according to the non-slip target surface. In addition, by changing the rubber insertion position for each course in units of left and right glances, various shapes can be created considering the function and design.
