Description

  The present invention relates to a knitting method of innerwear and a material for forming innerwear mainly by a circular knitting machine, and particularly to a knitting structure and a knitting method of a foot portion which becomes a knitted fabric end of a tubular knitted fabric. is there.

The end of a general knitted fabric has a curling property.
For example, in a knitted fabric formed in a cylindrical shape by a circular knitting machine or a flat knitting machine, the end of the set-up side or the end of the knitting end side is wound outward, and a pipe is attached to the part.
Therefore, in order to eliminate such curling wrinkles, for example, when forming a knitted fabric product with a cut and saw, as shown in Patent Document 1, the part is cut with an angle with respect to the knitted fabric wale. Has proposed to correct curl at the cut end portion.

However, such a method for preventing curling can be carried out when parts are cut to form a knitted fabric product, but a knitted fabric formed in a cylindrical shape by a circular knitting machine or a flat knitting machine is used as the method. It cannot be carried out when used in a cylindrical state, and the part is cut at an angle with respect to the wales of the knitted fabric, so there are many knitted fabrics that become unusable chips. There was also a problem that the yield would deteriorate.
Therefore, by using the tubular knitted fabric as it is, for example, in innerwear such as underwear for correction and underwear for sports, the end portion of the knitted fabric of the tubular knitted fabric is folded and doubled to prevent curling. At present, the edge processing is performed.

However, in innerwear that has been end-treated to prevent curling by folding the end of the knitted fabric into a double, it is used for correction to correct the body shape due to the thickness of the knitted fabric of the double part. In the case of underwear, there is a problem that this double part appears outside and the fashionability is impaired.
Furthermore, if the end of the knitted fabric is folded back and doubled, the tightening force of the part becomes too strong, and there is a risk of blood circulation being impaired in corrective underwear, and sports underwear impairs mobility. There was also a problem of fear.
Republished patent WO2004-1000068

  The present invention has been proposed in view of the above problems, without impairing fashionability when performed on underwear for correcting the body shape, and without local tightening when performed on sports underwear, It is an object of the present invention to make it possible to easily and inexpensively provide innerwear having a beautiful appearance and a high commercial value that does not impair sports performance.

  In order to achieve the above object, in the knitting method of the innerwear and the material for forming the innerwear according to the present invention, the innerwear and the innerwear knitted in a cylindrical shape from the foot portion toward the waist side A knitting method of forming material, in which loops are formed on all knitting needles by a set-up course, and in the subsequent knitting course, a knitting course in which three knitting needles are missed to form one loop is repeated a predetermined number of times. After that, one knitting needle forming the loop is missed, and a knitting course for forming a loop on the knitting needle formed on the three missed knitting needles and the three knitting needles are missed to form one loop. The knitting course is alternately and repeatedly knitted a predetermined number of times to form a curling prevention portion of the set-up portion of the foot portion, and then a tubular knitting above the foot portion with all knitting needles It is an most important feature that was to form the earth.

  Further, the innerwear and the innerwear forming material according to the present invention are innerwear and innerware forming material knitted in a cylindrical shape from the foot portion toward the waist, and are knitted by a set-up course. The set-up portion and the portion where three loops are missed following this set-up portion to form one loop, and the structure where the missed portion of the knitting yarn is a crossover yarn is repeated a predetermined number of times, A portion where the one knitting needle that formed the loop is missed, and the knitting structure in which the loop is formed on the knitting needle that is formed on the three missed knitting needles is alternately repeated a predetermined number of times, The main feature is that a curling prevention portion is formed in the set-up portion, and a tubular knitted fabric above the foot mouth portion is knitted from this curling prevention portion with all knitting needles. Than is.

In the present invention, the knitting machine used for knitting the inner wear and the material for forming the inner wear is a circular knitting machine having a plurality of yarn feeders, or the inner wear is sports underwear or straightening underwear. This is also a feature.

  According to the present invention, since there is no persimmon that curls the end of the tubular knitted fabric, a single knitted fabric can be obtained. As a result, it is possible to eliminate adverse effects such as the loss of fashionability due to double processing of the end portions as in the prior art and the possibility of impeding sports mobility due to strong tightening.

  In addition, when the tubular knitted fabric is knitted, the curling prevention portion is formed at the same time, so that there is no occurrence of a knitted fabric that becomes unusable chips like those described in Patent Document 1, so that productivity and economy are achieved. There is also an advantage that can be improved together.

  In order to achieve the above object, preferred embodiments of innerwear and a knitting method of a material for forming innerwear according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a rear view of underwear (so-called tights) which is an innerwear for sports according to the present invention. In FIG.
The underwear 1 is formed by combining left and right leg parts 2 and 3 formed in a cylindrical shape.

Each of the leg parts 2 and 3 is formed in a cylindrical shape by a circular knitting machine, and the circular knitting machine in this example has a yarn feeder (yarn feeder) 5 for the rotating cylinder 4 as shown in FIG. It is provided with 4 pieces and is highly productive so that 4 courses can be knitted with one rotation of the cylinder. It is knitted from the foot part 6 at the lower part of the figure, and is cylindrical toward the waist 8 through the heel part 7 Is organized.
And the curling prevention part 9 is formed in the foot mouth part (knitted fabric edge part) used as the set-up part.

Next, the formation of the curling prevention unit 9 will be described with reference to FIGS.
FIG. 3 shows the operation of the four yarn feeders (F1, F2, F3, F4) 5 of the circular knitting machine, and FIG. 4 is a structural diagram showing the structure of the curling prevention unit 9.
The numbers on the left side in FIGS. 3 and 4 indicate the order of the knitting course. The square ridges in FIG. 3 correspond to the knitting needles, the blanks indicate mistakes that do not form loops in the knitting needles, and x in the square ridges. Each part represents a knit forming a loop.

In the knitting course 1 of FIG. 3, loops are formed on every other knitting needle with the feeder 5 of F1, and loops are formed on all the needles in the knitting course 2, and at this time, other F2 and F3 are formed. -Feeder 5 of F4 is at rest.
As shown in FIG. 4, when all the knitting needles are formed in the knitting course 2 and the set-up is completed, one loop is formed by the feeder 5 of the F1 in the knitting course 3 and knitting is performed in which three knitting needles are missed. .
The knitting of the knitting course 3 is repeated in the knitting course 4, and the knitting yarn fed from the feeder 5 of the F1 in the knitting course 3 and the knitting course 4 passes through the three missed knitting needle portions and is in a state of a crossover yarn. It has become.

Thereafter, in the same way as the knitting course 3 and the knitting course 4 in the knitting course 5, the knitting yarn formed from the feeder 5 of the F1 forms one loop and misses three knitting needles. Knitting (knitting course 6 in FIG. 4) in which one of the knitting needles where the loop is formed by the feeder 5 of F1 is missed with the knitting yarn fed from 5 and loops are formed on the three knitting needles missed above. , A knitting (knitting course 7 in FIG. 4) that forms a loop on one knitting needle of the part missed by F2 with the knitting yarn fed from the feeder 5 of F3 (knitting course 7 in FIG. 4), and a feeder of F4 A knitting (knitting course 8 in FIG. 4) in which one of the knitting needles where the loop is formed by the feeder 5 of the F1 with the knitting yarn fed from 5 is missed and a loop is formed on the three knitting needles missed above. Rotating cylinder 4 makes one rotation Sequentially carried out by the.
In other words, four courses can be knitted by rotating the rotary cylinder 4 once.

Then, after the rotating cylinder 4 is further rotated once, the four courses are knitted (knitting courses 9 to 12 in FIG. 4), and then the bulge of the heel part 7 is formed with all the needles, and the lumbar part 8 side is reached. Be organized.
The tubular knitted fabric thus formed is cut from one upper side to the vicinity of the lower part of the buttocks, and two tubular knitted fabrics are formed in a state in which the cut portions are combined. When sewn face to face, underwear 1 as shown in FIG. 1 is formed.

  Here, after the knitting course 1 and the knitting course 2 are set up, when the curling prevention portion 9 shown in the knitting course 3 to the knitting course 12 is formed in FIG. 4, three knitting needles are crossed between one loop. The part that is the yarn (knitting course 3-knitting course 5, knitting course 7, knitting course 9, knitting course 11), and on the contrary, the part for three knitting needles that are the crossover yarn in the previous knitting course The part where the loop is formed and the part where the one loop is formed is a crossover yarn (knitting course 6, knitting course 8, knitting course 12) cooperates to generate the firewood of the knitted fabric. To prevent.

That is, after forming the loop with all the needles, curling occurs due to the elastic contraction force peculiar to the loop, whereas after forming three loops in the wale direction as in the present invention, alternately, the course direction By providing 1: 3, the shrinkage elasticity function peculiar to the knitted fabric is greatly increased by the synergistic effect of the strong shrinkage due to the loop and the knitting yarn with a low shrinkage elasticity that has been missed and does not form a loop. Without damaging, it is possible to suppress the occurrence of curling wrinkles while the edge of the knitted fabric is clean.
Incidentally, in order to increase the contraction elastic force of the curling prevention portion 9, it is desirable to use an elastic yarn such as FTY for the knitting yarn of the portion.

In the above-described embodiment, seven courses are formed by alternately forming loops and mistakes after forming three loops in the wale direction after setting up, or after making mistakes for three courses. The number of courses in which the loop and the miss are alternately formed can be arbitrarily set.

  In the above embodiment, after setting up, after repeating a knitting course in which three knitting needles are missed to form one loop a predetermined number of times, one knitting needle that has formed the loop is missed, and the above-mentioned mistake is made. A knitting course in which loops are formed on three knitting needles and a knitting course in which the above three knitting needles are missed to form one loop are alternately knitted a predetermined number of times. Is set to 1: 3 · 3: 1. If the ratio of the error and the loop of the curling prevention portion is set to 1: 2 · 2: 1 or less, the curling prevention effect of the curling prevention portion is reduced. This is because if the ratio between the mistake and the loop is 1: 4 · 4: 1 or more in the knitting direction, the transition yarn portion becomes longer, the curling prevention portion does not stretch, and it becomes difficult to wear.

Further, in the above embodiment, a circular knitting machine in which four yarn feeders 5 are provided with respect to the rotating cylinder 4 is illustrated. However, the present invention is not limited to this, and one yarn feeder 5 may be used. Of course, the number is not limited to this example.
Needless to say, the present invention is not limited to circular knitting machines, and can also be carried out when knitting into a cylindrical shape with a flat knitting machine.

FIG. 2 is a rear view of tights which is innerwear for sports according to the present invention. FIG. 4 is a schematic view showing the position of a feeder with respect to a cylinder of a circular knitting machine for knitting innerwear for sports according to the present invention. FIG. 5 is a view showing yarn feeding from a plurality of feeders for knitting a foot opening portion from the set-up of sports innerwear according to the present invention. FIG. 4 is an organization chart of the foot and mouth portion from the set-up of the innerwear for sports according to the present invention.
