DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubular three-dimensional knitted fabric such as socks, high socks, over knees and supporters knitted by a flat knitting machine, and a method of knitting the same.

[0002]

2. Description of the Related Art Socks, high socks, over knees,
When knitting a knit product (tubular knitted fabric) such as a supporter with a flat knitting machine, knit the front part of the tubular knitted fabric with the front needle bed and the rear part of the tubular knitted fabric with the rear needle bed. When expanding or reducing the inner diameter of the tubular knitted fabric according to the undulating shape of the foot or body, change the number of wales by increasing or decreasing the stitches at both ends of the needle bed evenly left and right, The inner diameter of the tubular knitted fabric is changed.

[0003]

However, the above socks,
A body that wears a knit product such as a high sock, an over knee, a supporter, or the like has a large undulating shape between the front surface portion and the back surface portion. However, in the knitting of the above-mentioned conventional knit product, the front knitted fabric portion of the knit product is used in one of the front needle bed or the rear needle bed of the pair of needle beds facing each other, and the knit product is used in the other. Since the rear knitted fabric portions are knitted respectively, the number of loops in either the front knitted fabric portion or the rear knitted fabric portion cannot be increased or decreased, and it is difficult to follow the shape of the body to be worn. Had become a product.

That is, the number of loops hooked on the knitting needles of the front needle bed and the number of loops hooked on the knitting needles of the rear needle bed must be substantially equal to each other. The tension of the transfer yarn passing from the knitting needle to the knitting needle of the rear needle bed is locally increased, causing thread breakage or a longer loop length due to the expanded knitting yarn, thereby deteriorating the commercial value of the product. Therefore, the number of loops hooked on the knitting needles of the front needle bed and the number of loops hooked on the knitting needles of the rear needle bed are greatly changed, so that the shape differs before and after the tubular knitted fabric. The undulation cannot be formed.

The number of loops in either the front knitted fabric portion or the rear knitted fabric portion is increased or decreased to determine the number of loops hooked on the knitting needles of the front needle bed and the knitting needles of the rear needle bed. In order to eliminate this difference when there is a difference between the number of loops and the number of loops to be hooked, it is considered in some cases to transfer between the front and rear needle beds. At present, it takes a lot of time and effort to perform operations such as transfer, low productivity, and practically no practical use.

[0006] The present invention has been proposed in view of the above problems, and an object of the present invention is to enable a low-cost knit product having a high commercial value that fits well with the shape of a body to be worn. .

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, a tubular three-dimensional knitted fabric according to the present invention differs in the number of wales between a front part and a rear part of a tubular knitted fabric, and is different from a front part. A different undulation is formed on the rear surface portion.

The knitting method of a tubular three-dimensional knitted fabric according to the present invention uses a flat knitting machine having a pair of needle beds opposed to each other in a front-to-back direction, after knitting is performed from one end of the tubular knitted fabric. The yarn is fed in a circular shape to knit a tubular knitted fabric, and one side of the tubular knitted fabric on one side of the front and rear needle beds,
On the other hand, in knitting the other side surface portion of the tubular knitted fabric, and forming undulations by increasing or decreasing the stitches on the front portion and the rear portion of the tubular knitted fabric, a needle forming the front portion of the tubular knitted fabric By making the wale of the bed part and the wale of the needle bed part on the side forming the rear part different, the number of increase and decrease is different, so that different undulations are formed on the front part and the rear part of the tubular knitted fabric. It is assumed that.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a knitting method for a tubular three-dimensional knitted fabric according to the present invention will be described below using a sock as an example. In this embodiment, a sock as shown in FIGS. 1 and 2 which is an example of a tubular knitted fabric is knitted, and reference numeral 1 in the figure indicates the sock as a whole.

The sock 1 is knitted from the foot insertion opening 2 and has a bulging shin 3 having a swelling, an ankle 4 having a small diameter, a swelling heel 5, a shaved arch 6 and a toe 7. It is formed by sequentially knitting.

A predetermined width portion from the foot insertion opening 2 is formed into a rib knit into which a rubber thread is inserted, and the rib knit and the elastic force of the rubber thread form a straight small-diameter fastening portion 8.
Then, as shown by the imaginary line in FIG. 2, the shape of the foot on which the socks are worn is such that the front portion 9 has a gentle swelling, while the rear portion 10 has a large and swelling shape.

The flat knitting machine used in the present invention comprises:
A needle bed in which two knitting needles are slidably inserted into a gauge is disposed in front and rear in a "C" shape in a side view in a state in which the teeth are close to each other. Each knitting needle is moved forward and backward by a carriage that slides on the upper surface, and a well-known structure in which the front and rear needle beds are relatively movable (racking) is used. One side portion (for example, left side portion) 11 of the tubular knitted fabric is knitted on the other side, and the other side portion (right side portion) 12 of the tubular knitted fabric is knitted on the other side.

Therefore, the knitted fabric portion of the front part 9 of the foot is the left half of the front and rear needle beds, and the rear part 10 of the foot is
Will be knitted in the right half of the front and rear needle beds, respectively. The calf shin 3 following the small-diameter tightening portion 8 increases or decreases the number of stitches as shown in FIG. It is organized while.

That is, the knitting of the loop at the right end of the knitted fabric for knitting the knitted fabric of the cylindrical small-diameter tightening portion 8 made of ribs into which rubber yarns have been inserted after the knitting is finished, is performed by using two loops at a time.
This stitch reduction operation is performed by transferring the loop hooked to the knitting needle of the needle bed facing the front and back at the right end of the knitted fabric to one knitting needle side, A new loop is formed by feeding yarn to a knitting needle with a double loop, and the needle bed is moved to the side where the newly formed loop overlaps the loop of the knitted fabric, and then a new loop is formed. This is a well-known stitch reduction operation in which the loop is transferred to and overlapped with the loop of the knitted fabric, and a new loop is formed here.

At the places where the eyes are reduced, so-called "fashion marks" 13, 13, 13,. Then, at the ankle 4 part, the loop is increased for the ankle 5 part, and the loop is increased by the eyes. This increase is
It is called "split increase", and one of the loops at the end of the knitted fabric is also split into the empty needles of the other needle bed and hooked, and the knitting yarn supplied at the time of the introduction knitting, respectively. To form a new loop.

When the cylindrical knitted fabric has a predetermined diameter by the above-mentioned "split increase", five heels are formed in the right half of the knitted fabric.

The knitting of the heel 5 portion is such that the knitting needle which is hooked on the loop of the left half of the knitted fabric is in a rest state, and the knitting yarn extends over the knitting needles before and after knitting the right half of the knitted fabric. When the number of needles to be fed is gradually reduced, and then the number of needles to be fed is returned again, five minutes of heels are formed. After the heel 5 portion is formed, the instep portion 14 is formed in a cylindrical shape having substantially the same diameter, and when the toe portion becomes 7 portions, the eyes are gradually reduced from both ends to the center portion of the knitted fabric. It becomes the small-diameter toe 7 portion to be edge-processed.

In the end treatment of the toe 7, the tubular fabric formed by the front and rear needle beds is transferred to one of the front and rear needle beds and overlapped, and a new loop is formed therein to form a cylindrical opening. After closing the new loop, the new loop is bound off from one side to the other. When the knitted fabric is wiped off from the flat knitting machine after the edge portion is bound off, the sock 1 is completed.

In the above example, the rear part 1 of the calf 3 is used.
4, the front part 9 of the calf 3 is also reduced by reducing the front part 11 in addition to the rear part of the calf 3 as shown in FIG.
It goes without saying that it can be made to fit the gentle bulge. Furthermore, in the above example, the knitting of socks has been described as an example, but the present invention is not limited to such a knitting, and it goes without saying that the present invention can be applied to a tubular knitted fabric such as high socks, over knees, and supporters.

[0020]

As described above, according to the present invention, after knitting is performed from one end of a tubular knitted fabric, the yarn is fed in a circular manner to knit the tubular knitted fabric, and one of the front and rear needle beds is knitted. When knitting one side portion of the tubular knitted fabric and the other side portion of the cylindrical knitted fabric on the other side, when forming undulations by increasing or decreasing the stitches on the front and rear portions of the tubular knitted fabric,
The knitting of the tubular knitted fabric is made different by increasing and decreasing the number of the wale of the needle bed portion on the side forming the front portion of the tubular knitted fabric and the wale of the needle bed portion on the side forming the rear portion of the tubular knitted fabric. Different undulations can be formed between the front part and the rear part.

[0021] Thereby, there is an advantage that a knit product which is comfortable and has a high commercial value according to the shape of the body to be worn can be produced.

Moreover, by increasing or decreasing the loop on one side of the front and rear needle beds, different undulations can be formed between the front part and the rear part. The tension of the jumping yarn passing over the knitting needle of the needle bed is locally increased, which may cause yarn breakage and increase the loop length due to the expanded knitting yarn, lowering the commercial value of the product. The number of loops of only one of the front knitted fabric portion and the rear knitted fabric portion is increased or decreased, and the number of loops hooked on the knitting needles of the front needle bed and the rear needle When there is a difference between the number of loops to be hooked on the knitting needles of the bed and to eliminate this difference, knit products with increased productivity without the need to transfer between the front and rear needle beds Made inexpensively There is also an advantage that it is possible to be.
