Description

  The present invention relates to socks such as stockings and socks that have been improved in the knitting of a toe portion including a toe zone and the knitting of a heel portion having a gore line zone, and a low elastic yarn for sock knitting used therein.

  In the text, the stitching edge at the tip of the toe portion and the peripheral portion thereof are referred to as a leading (forward) zone, and the gore line forming portion and the peripheral portion thereof are referred to as a gore line zone.

  The socks are knitted into a cylindrical knitting shape (circular knitting) by using a circular knitting machine to make the stitches coarse or dense. The circular knitting machine has a different number of needles, and is mainly used from a class of 100 called a course gauge to a class of 176 called a middle gauge and a class of 400 called a high gauge.

  In the case of the above course gauge and middle gauge, since the stitches are large, it is possible to knitting a sock with a top seam type in which the seam of the toe part is on the upper part of the base of the toe. On the other hand, in the case of using a high gauge, the number of needles is large, the stitches are small, and the shrinkage is small. Therefore, when knitting socks with the toe portion as the top seam 14, conventionally, the same as other portions. Since the yarn is used, an ear-shaped projecting angle portion (hereinafter simply referred to as an ear) 15 is formed at the end of the tip zone, and a low-value product is manufactured (see FIG. 3B). For this reason, in the case of using a high gauge, a side seam 16 method (see FIG. 3C) is employed in which the toe portion is knitted straight and the tip edge is sewn with a sewing machine.

  However, in the case of a sock made of a side seam type, there is a problem that the seam formed on the front edge of the toe hits the toe of the foot and the feeling of wearing is not good. On the other hand, in the case of a sock with a top seam type, although there are advantages such as prevention of per-seam, improved appearance of the toes, and improved wearing feeling, the ears 15 projecting to the left and right are formed as described above. There was a fatal problem.

  The left and right ears projecting as described above, for example, the knitting of the toe part including the pointed zone and the knitting of the heel part having the gore line zone are matched to the thickness of the yarn forming the leg part and the foot part. In the same way, for example, a highly elastic (high elasticity) elastic yarn (hereinafter referred to as spandex (trade name), etc., which is made of a highly elastic polyurethane elastic yarn, stretched 3-6 times, and double-covered with a nylon yarn. This elastic yarn was conventionally produced using an elastic yarn), and this occurred.

  In addition, the products using the above-mentioned conventional elastic yarns have the greatest characteristic in contractibility (stretching strength), and in this state, the knitting and buttocks of the toe part are finished small and look good. When worn, the toe portion may become painful due to the tightening power of the conventional elastic yarn, which is not necessarily suitable for long-time wearing.

  In view of the above situation, the present inventor can provide a sock by a top seam type high gauge in which ears are not formed to protrude from the left and right ends of the leading zone or the left and right ends of the gore line zone. It has succeeded in making it.

  That is, in the present invention, the elongation of the core yarn, which has been used in the state of being stretched 3 to 6 times as in the leg portion and the foot portion, is 1.5 to 2.5 times the stretch state in the present invention. A new low elastic yarn is obtained by double covering two nylon yarns in the state of the core yarn having a low stretch rate while making the core yarn in a low state, and selectively using the low elastic yarn. It was possible to find out while repeatedly making prototypes of the top seam and gore line zone with high gauge.

  In the text, the above-mentioned low elastic yarn is a yarn having a property of low elasticity that is difficult to stretch and shrinks, and is used as a synonym of a high elasticity yarn of a property having high elasticity that is easy to stretch and shrink. .

  An object of the present invention is to provide an improved high gauge sock and a low elastic yarn for sock knitting so as not to have an ear protruding at the end of the leading zone or the end of the gore line zone.

  In order to achieve the above object, the sock according to claim 1 has a tip zone, a toe portion including the tip zone, a gore line zone, and at least one of the heel portions including the gore line zone. Unlike conventional thread use, polyurethane elastic yarn core yarn is knitted with low elastic yarn that is double covered with covering yarn such as low elastic nylon yarn while keeping 1.5 to 2.5 times the stretched state. It is characterized by becoming.

  The low elastic yarn for sock knitting according to claim 2 is a core yarn having a low expansion / contraction rate by extending the core yarn, which has been stretched 3-6 times, to 1.5-2.5 times. In addition, it is characterized in that the core yarn in the state of low expansion and contraction is constituted by double covering a covering yarn such as a low elastic nylon yarn.

  According to the present invention, for at least one of the tip zone, the toe portion including the tip zone, the gore line zone, and the heel portion including the gore line zone, conventionally, the leg portion, the foot portion, etc. The core yarn of the polyurethane elastic yarn used in the state of being stretched 3 to 6 times in the same manner as in the part No. 1 is made 1.5 to 2.5 times the stretched state, and this low stretch rate core yarn is obtained. At the same time, it is knitted using yarn obtained by double-covering a low-elasticity nylon yarn or other covering yarn to the low-stretching stretched core yarn. The conditions that can improve the appearance with the shrinkage rate and the conditions that can alleviate the discomfort that the toes of the toes are tightened and hurt when worn are satisfied, and as a result, the end of the fore zone and the left and right ends of the gore line zone To without the ear is protruded, we can provide a sock by superior high-gauge with high commercial value never discomfort caused when worn.

  The sock according to the embodiment of the present invention shown in FIG. 1 and FIG. 3A is an extension of a conventional core yarn (common name: draft) that has been used by stretching an elastic yarn material such as polyurethane yarn 3 to 6 times. ) To 1.5 to 2.5 times the stretched state of the core yarn 1 having a low stretch rate (hereinafter referred to as the new core yarn 1), and the low stretched state of the new core yarn 1 has a low elasticity. The low-elastic yarn 4 is completed by double-covering the upper and lower covering yarns 2 and 3, and the low-elastic yarn 4 forms a shallow bag having a deep toe portion 6 including a leading zone 5 and a gore line zone 7. This is a stocking 9 in the form of a top seam 9 a knitting the heel part 8.

For example, a polyurethane elastic yarn of about 20 denier is used for the core yarn 1, and a nylon yarn of about 70 denier is used for the covering yarns 2 and 3, for example. In the figure, reference numeral 13 denotes a gore line provided on the toe portion 6.
In addition, the thread | yarn used for the piercing | opening part 10, the leg part 11, and the foot part 12 is the same thread use as the past, and the nylon thread was double-covered to the core thread which extended the polyurethane elastic thread 3-6 times. Since it is manufactured using a conventional elastic yarn having a high stretch force (high elasticity), detailed description thereof is omitted here.

  In addition, when the elongation state of the core yarn 1 is smaller than 1.5 times or larger than 2.5 times, the condition that the appearance can be improved with the minimum shrinkage rate and the condition that the feeling of strangeness at the time of wearing can be alleviated are satisfied. It is not possible to obtain sufficient results.

  In addition, since the present invention may be a new core yarn and covering yarn satisfying the conditions that can improve the appearance with a minimum shrinkage rate and the conditions that can alleviate discomfort (pain) when worn, Name), etc., and low elasticity upper and lower covering yarns using nylon yarn. Also, a finished product in which only the leading zone 5 or only the gore line zone 7 or both are knitted with the low elastic yarn 4, a finished product in which the entire toe portion including the leading zone 5 is knitted with the low elastic yarn 4, gore line It is optional to obtain a finished product obtained by knitting the entire collar including the zone 7 with the low elastic yarn 4 or a finished product obtained by knitting both with the low elastic yarn 4.

  According to the present invention, if the low elastic yarn is used, it is possible to manufacture a side seam type sock and an under seam type sock in which the seam of the toe portion is on the lower side of the base of the toe (the sole side). Even in this case, the same effect as the top seam type socks can be obtained.

It is a side view which shows embodiment of this invention. It is a conceptual diagram which shows a low elastic yarn. It is an expansion conceptual diagram which shows a toe | tip part, (a) shows the toe part of this invention, (b) shows the example made into the conventional top seam type, (c) shows the example made into the conventional side seam type.
