Description

  The present invention relates to a sock and a knitting method thereof, and particularly to a sock excellent in a feeling of wearing and a knitting method thereof.

The shape of the foot wearing socks is generally the same in that it includes fingers, arches, heels and heels, and ankles and calves, but the shape of each part is different.
Therefore, in order to fit each of these parts when wearing the socks, as shown in Patent Document 1, when knitting the socks, an elastic yarn is inserted, and a desired part is obtained by the contraction force of this elastic thread. It has been known to fit to different shapes by tightening.

  In the above-mentioned Patent Document 1, a plurality of elastic yarns floated during knitting of socks are tucked every other knitting needle, and the tucked portion is knit with knitting yarn of the next knitting course. A plurality of elastic yarns are held by tucking a knitting yarn onto a knitting needle in a portion where the elastic yarn is missed, and further tucking on a portion where the knitting yarn is missed in the knitting course in the subsequent knitting course. The organization course is repeated.

In such a case, since the plurality of inserted elastic yarns are held in a line shape, the tightening force also acts locally and annularly.
Therefore, for example, when a knitted fabric of such a tissue is applied to a calf or a foot insertion port portion, the tension of the elastic yarn must be increased to prevent the displacement movement, and as a result, only the feeling of wearing is reduced. If the skin elasticity is low, such as elderly people or diabetics, blood flow in the calf or foot insertion port may be obstructed, or pressure marks may be left on the calf or foot insertion port. There was a problem that

  The present invention has been proposed in view of the above-mentioned problems, and by making the tension for tightening the portion where the elastic yarn is inserted uniform, the wearing feeling is improved and the shifting movement is firmly secured even with a weak tension. It is an object of the present invention to provide a sock that can be prevented and a knitting method thereof.

  In order to achieve the above object, the sock according to the present invention is knitted by feeding a knitting yarn in a circular shape from the toe portion to the foot insertion port portion or from the foot insertion port portion to the toe portion, and at least the foot insertion port portion. In a sock formed by inserting a shrink elastic yarn in the vicinity thereof, the knitting yarn is composed of a front yarn that appears on the surface of the sock and a back yarn that appears on the back surface, and the back yarn is formed of an elastic yarn. A shrinkage elastic knitted fabric formed by repeating a knitted portion in which the knitted and tacks are alternately repeated in the knitting course direction of the formed back yarn, and a knitted portion formed by knitting the front yarn and the back yarn made of an elastic yarn. The main feature is that the portion forms the foot insertion opening portion of the sock or the knitted fabric portion in the vicinity thereof.

  Further, in the sock according to the present invention, a plurality of finger bags are formed on the toe side portion, and the tubular knitted fabric portion from the plurality of finger bag portions to the foot insertion opening portion or the vicinity thereof is a surface yarn. It is also characterized in that it is formed of a tentacle structure with a back yarn made of an elastic yarn.

  In the sock knitting method according to the present invention, knitting yarn is fed in a circular manner to a knitting needle of a knitting machine and knitted from the toe portion toward the foot insertion port portion, or from the foot insertion port portion toward the toe portion. In a sock knitting method in which a tubular foot insertion port side portion is knitted with knitting yarns that are knitted and fed in a circular shape, and a contraction elastic yarn is inserted into the foot insertion port portion or its vicinity to knitting The knitting yarn to be fed is composed of a front yarn appearing on the surface of the sock and a back yarn appearing on the back surface, the back yarn is formed of an elastic yarn, and the knitting course direction is formed only by the back yarn formed of this elastic yarn. The foot insertion opening of the sock is formed by a shrinking elastic knitted fabric portion formed by repeatedly repeating a knitting course in which knit and tack are alternately repeated and a knitting course knit with a front yarn and a back yarn made of elastic yarn. Or knitting the knitted fabric part in the vicinity It is an most important feature that was.

In the sock knitting method according to the present invention, the knitting machine is a flat knitting machine provided with at least one pair of front and rear needle beds in which knitting needles are slidably moved back and forth, or knitted from the tips of a plurality of finger bags. The tubular knitted fabric portion from the portion where the plurality of finger bags are united to the foot insertion opening portion to the vicinity thereof is knitted with a tense structure with a front yarn and a back yarn comprising an elastic yarn. This is also a feature.

    According to the present invention, the knitting yarn to be fed is composed of a front yarn appearing on the surface of the sock and a back yarn appearing on the back surface, the back yarn is formed of an elastic yarn, and knit and tack are alternately arranged in the knitting course direction. After that, the back yarn formed by the elastic yarn supplied repeatedly is knitted with the front yarn and the back yarn consisting of the elastic yarn, so that the surface of the structure may have a portion consisting only of the back yarn. It presents an overview of the rib knitting, and the structure itself has great elasticity and can be greatly expanded and contracted.

As a result, the tucked elastic yarn and the knitted elastic yarn are entangled with each other, the tension is dispersed and uniform, and even if the tension is weakened, sufficient holding power can be exerted. There is an advantage that it is possible to provide a sock and a knitting method capable of providing a good feeling and firmly preventing slippage even with a weak tension.
Further, according to the sock knitting method of the present invention, the knitting portion in which the back yarn formed by the elastic yarn is alternately knit and tucked, and the knitting portion is knit by the front yarn and the back yarn made of the elastic yarn. This is a simple method in which a leg insertion opening portion of a sock or a knitted fabric portion in the vicinity thereof is formed by a contracted elastic knitted fabric portion formed by repeating the portion, and there is an advantage that can be carried out with an existing knitting machine.

FIG. 3 is a plan view (back side) of the sock according to the present invention. These are the knitting course figures of the sock concerning this invention. FIG. 2 is a partially enlarged view of a tissue of a sock according to the present invention.

  The most preferred embodiments of the sock and its knitting method according to the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view (back side) of a sock having a tightening portion according to the present invention, and FIG. 2 is a bottom view (back side of a foot) thereof. In the figure, reference numeral 1 generally indicates the sock.
Although not shown in the figure, the sock 1 is provided with a needle bed in which a knitting needle is slidably mounted in a front and back shape in the shape of a letter “C” in a side view in a state where the mouth part is close to each other. Each knitting needle is knitted into a sock with fingers having five finger bags using a so-called flat knitting machine having a well-known structure in which each knitting needle can be moved forward and backward by a carriage that slides on the upper surface of the bed.

As shown in FIG. 3, the yarn feeder that is entrained in conjunction with the sliding of the carriage and feeds the knitting needle is used for feeding at least the front yarn 16 that appears on the front side and for feeding the back yarn 17 that appears on the back side. And are provided.
The above surface yarn is a so-called elastic yarn in which synthetic fibers such as nylon fiber and polyester fiber, natural fibers such as cotton and silk, or a blend of these are used, and the outer periphery is covered with a covering yarn as a polyurethane fiber core as a back yarn (FTY) is used.

A sock with fingers 1 shown in FIG. 1 is a sock with fingers having five finger bags on a toe side portion, and feeds the knitting yarn in a zigzag manner over the knitting needles of the needle beds before and after the flat knitting machine. Then, each of the finger bags 2 for the thumb, the finger bag 3 for the index finger, and the finger bag 4 for the middle finger formed from the toe portion is formed, and these finger bags 2 to 4 are combined. After the main body 5 is knitted for a predetermined course, a finger bag 6 for the ring finger is knitted.
After the four cylinders 7 in which the three cylinders 5 and the ring finger fingers 6 are united are knitted into a cylindrical shape, a finger bag 8 for the little fingers is knitted, and the four cylinders 7 and the fingers for the little fingers are knitted. The five trunks 9 of the sock 1 with one bag 8 are knitted for a predetermined course.

When the five trunks 9 are formed, the arch portion 10 and the heel portion 12 having a substantially triangular shape are formed on the bottom portion, and then the foot insertion port 15 through the calf 14 from the ankle portion 13 where the tightening portion 12 is formed. It is knitted into a cylinder.
At this time, for the tubular knitting from the five finger bags 2, 3, 4, 6, 8 to just before the ankle portion 13 where the tightening portion 12 is formed, the knitting course 1 and the knitting course of FIG. As shown in Fig. 2, the surface yarn 16 made of synthetic fiber such as nylon fiber or polyester fiber, natural fiber such as cotton or silk, or a blended yarn thereof and the elastic yarn are fed in a circular manner on the same knitting course. Yarn is knitted.

Then, the tubular knitting from the ankle portion 13 where the tightening portion 12 is formed to the foot insertion port 15 through the calf portion 14 is performed in the knitting course shown in FIG.
In FIG. 2, the number in the “course” portion on the left is the knitting course by yarn feeding from the yarn feeder, the letter B is the needle bed on the front side of the flat knitting machine, F is the needle bed on the back side, and the “direction” arrow Is a sliding direction of a carriage (not shown) entraining the yarn feeder, and “knitting state” indicates the type of knitting yarn fed to the knitting needle.

The knitting course 1 and the knitting course 2 in FIG. 2 are knitting portions of the ankle portion 13 immediately before the tightening portion 12 in FIG. 1 is formed. In this knitting, the front yarn 16 and the back yarn 17 are front and rear. The cylindrical ankle portion 13 is knitted by supplying the yarn in a circular manner over the knitting needles of the needle bed.
Next, when the back yarn 17 made of an elastic yarn is fed to the knitting needles of the front and rear needle beds in a circular manner in the knitting course 3, the knitting needles of the front and rear needle beds are alternately and repeatedly knit and tucked. Is fed.

In the knitting course 4, the front yarn 16 and the back yarn 17 are knitted by feeding the knitting needles of the front and back needle beds in a circular manner, and in the knitting course 5, the back yarn 17 made of an elastic yarn is used in the same manner as the knitting course 3. After the knitting and the tuck are alternately repeated, the yarns are fed to the knitting needles of the front and rear needle beds, and then the front yarn 16 and the back yarn 17 are fed to the knitting needles of the front and rear needle beds in a circular manner on the knitting course 6. And knit.
Thereafter, the knitting of the knitting course 3 to the knitting course 6 is repeated as many times as necessary to reach the foot insertion opening 15, where the end of the knitting course 15 is processed, bent inward, and sewn to the inner surface. Then, the knitting of the socks 1 is completed.

Thus, the knitted sock 1 has a back yarn 17 formed of elastic yarns that are supplied by alternately repeating knitting and tacking in the knitting course direction as shown in the enlarged view of the structure in FIG. Since the surface yarn 16 and the back yarn 17 made of elastic yarn are knitted, the surface of the structure has an appearance of the rib knitting R as if the portion made only of the back yarn 17 is hollow.
Further, since the tucked elastic yarn and the elastic yarn knitted together with the front yarn 16 are intertwined with each other, the tension is dispersed and becomes uniform.

In the above embodiment, the sock 1 is illustrated as a sock with a finger. However, the present invention can be applied to a sock without a finger pouch, as well as a circular knitting instead of a flat knitting machine. It can also be knitted on a machine.
Furthermore, in the above embodiment, the sock 1 is knitted from the toe portion side, but it goes without saying that the sock 1 can be knitted from the foot insertion port side.
