Abstract

PROBLEM TO BE SOLVED: To provide stockings that does not ruin wearability and texture of the stocking and has a design fitting to a shape of legs to obtain a comfortable fitting feeling (pressurized feeling) of individual parts; and a method for forming the stockings.SOLUTION: Elastic yarn, such as polyurethane yarn, in a bear state without being covered is used for at least one thread among threads to be used in the formation of the stocking, and in the formation of the stocking with the use of the bear elastic yarn, different tension is applied to the bear elastic yarn by using yarn tension control and a yarn feeding device depending on parts to be formed. In other words, the tension of the bear elastic yarn to be used is decreased for the formation of thigh parts of leg parts, and the tension of the bear elastic yarn is increased for the formation of ankle parts. In order to further improve the fitting feeling, the size of stitches (mesh size) is varied depending on the parts to be formed; for example, the mesh size of the thigh parts of the leg parts is increased, and the mesh size of the ankle parts is decreased in the formation.SELECTED DRAWING: Figure 1

Description

  The present invention relates to stockings and a knitting method that can freely change a feeling of wearing for each part, and thereby can provide a feeling of fit and softness that has not been conventionally available.

  Stockings here refers to all legwear including long-length or short-length stockings, pantyhose, thin tights, leggings, trenka, etc., regardless of the presence or shape of the panty, leg, or foot. Point to.

  Normally, stockings are made by covering non-elastic yarn such as nylon yarn (single covering or double covering) with a core yarn of elastic yarn such as polyurethane yarn (hereinafter simply referred to as “supporty yarn”). Or two types of yarns, that is, the support yarn and an inelastic yarn such as nylon yarn.

  The support yarn is produced by winding (covering) an inelastic yarn while stretching the elastic yarn of the core yarn (while applying a so-called constant tension). When knitting using this support yarn, knitting is performed while applying a certain tension.

  When knitting stockings, if the type is plain, the same support yarn or support yarn and non-elastic yarn such as nylon yarn are usually used from the thigh to the toe portion. By changing only the size (degree) of the stitch according to the part, the dimension (perimeter) is changed. That is, when knitting with the same yarn and the same knitting machine, the thigh part with a large circumference is knitted with a large stitch, the ankle part with a small circumference is knitted with a small stitch, and the number of stitches in the course direction itself changes. There is no.

  In order to increase the fit (wearing pressure), there are a method in which the size of the stitch is designed to be small and the size (circumferential length) is reduced, or a method in which the elastic yarn of the core yarn is thickened and the stretch back is strengthened. However, these methods result in products that are difficult to wear as a result of improving fit. Further, since the size of the stitches is determined by the knitting machine and the thickness of the yarn, there is a certain limit. Moreover, thickening the elastic yarn results in a product having a hard texture because the stockings are not transparent and the eyes are clogged.

  In recent years, a lot of products with a pressure-applying function have appeared, and in women's stockings, ankles have a pressure of 9-30 hPa, and in medical elastic stockings, more than 30 hPa have appeared, widely recognized by women. Has been. Among these, the pressure stockings as ladies' miscellaneous goods mainly have three kinds of knitting methods. That is, one is a product of zokkiki (plain knitting) using only the above-mentioned supporty yarn in the leg part, one is a product of knitting using supporty yarn and inelastic yarn in the leg part, and the other is supporty It is a product of knit mistake knitting (not plain knitting) using yarn and inelastic yarn in the leg part.

  However, the Zokki product has a high followability to the movement at the time of wearing, so that it is easy to obtain a comfortable wearing feeling when worn, but there is a drawback that it takes time to wear because the flat dimension is small. In addition, the knitting product has a large flat size and is easy to wear, but because the amount of supporty yarn used is half that of the Zokki product, it is difficult to produce a high pressure value, and compared to the Zokki product. Therefore, there is a drawback that the followability is low. In addition, the product of knitting mistake knitting has a large flat size, a high pressure value with a design that is difficult to stretch, and easy to wear, but it is easy to loosen if it does not match your size when worn, There is a drawback of being cramped.

  Therefore, in order to obtain a stronger pressure value and a stronger fit, it is still necessary to make the stitches smaller or make the elastic yarn thicker. As a result, it is difficult to wear and has a tight feeling. There is a problem that the product is far from a comfortable fit.

None

None

  In view of such a conventional problem, the present invention has a comfortable fitting feeling (compression feeling) for each part by making the design suitable for the shape of the leg part without impairing the ease of wearing and texture of the stockings. The present invention relates to stockings that can be obtained and a knitting method thereof.

  One of the features of the present invention is knitting using elastic yarns such as bare polyurethane yarns that are not covered with at least one of the yarns used when knitting stockings. To do.

  Another feature of the present invention is that when inserting the bare elastic yarn into the knitting machine, a portion to be knitted using a yarn tension control or a yarn feeding device (for example, a rolling feeder). Knitting with different tension on the bare elastic yarn. That is, the tension of the bare elastic yarn used for knitting the thigh portion of the leg portion is weakened, and when the ankle portion is knitted, the tension of the bare elastic yarn is increased.

  Further, the present invention adjusts the degree of the knitting machine when knitting by inserting the above-described bare elastic yarn, and knitting by changing the size of the stitch (degree) according to the part to be knitted. . That is, the leg is knitted with a large thigh stitch and a small ankle stitch.

  As described above, according to the stockings according to the present invention, the stretch rate of the elastic yarn of the bear can be freely changed depending on the portion to be knitted, so that, for example, the thigh fit and the ankle fit It can be changed according to the circumference of the leg part, and it becomes stockings having a high fit with a wearing pressure.

  Furthermore, since it can be adjusted only by the tension of the bare elastic yarn without changing the size of the stitches, the texture of the stockings is good and the stockings are easy to wear.

  Further, in addition to the strength of the bare elastic yarn, by changing the degree of the knitting machine and adjusting the size of the stitch, it is possible to design a larger adjustment range for the fit and the wearing pressure. As a result, it is a stocking with a good texture that has high follow-up performance and is easy to wear even though it has a high wearing pressure design.

  Furthermore, even if non-elastic yarn such as 10-40 denier nylon yarn having low fit and excellent transparency is used, the above knitting method provides a fit and high transparency stockings. You can also

It is explanatory drawing which shows an example of the knitting structure of the state which expanded the stitch of the stockings which concerns on this invention. It is a microscope picture of the knitting structure | tissue shown in FIG. (A)-(c) It is an image figure which shows the difference between the pantyhose according to the prior art and the present invention, and FIG. 3 (a) is a conventional Zokki knitting or cross knitting pantyhose with a large thigh stitch and ankle part The stitches are made small and knitted so that the whole is tapered toward the toe portion. FIG. 3B shows an example in which one or more of the elastic yarns of the bear used are knitted with different tensions depending on the part without changing the size of the stitches from the thigh to the ankle. It is. In addition to the method of FIG. 3 (b), FIG. 3 (c) is an example in which the thigh part has a larger stitch and the ankle part has a smaller stitch to give a stronger fit and wearing pressure. Show.

  Hereinafter, as an embodiment of the present invention, a pantyhose will be described as an example and described with reference to the attached Table 1 and FIGS.

  The following Table 1 is a table showing examples of combinations of knitting yarns used when knitting stockings according to the present invention.

  In the present invention, knitting is performed by using bare (uncovered) elastic yarn (for example, polyurethane yarn) in which at least one of the yarns constituting the knitting yarn is not covered with non-elastic yarn such as nylon yarn.

  In Table 1, “elastic yarn + inelastic yarn” indicates that at least one bare polyurethane yarn elastic yarn and one or more non-elastic yarns such as nylon yarn are bundled (so-called alignment). It means something. Further, the expression “elastic yarn + support yarn” means that at least one elastic yarn such as bare polyurethane yarn is arranged in addition to the above-described support yarn.

  Accordingly, the present invention includes not only knitting with two types of support yarns and elastic yarns, but also knitting with a combination of two types of yarns of non-elastic yarns and elastic yarns that do not use any support yarns. One or more bare elastic yarns may be used.

  That is, according to the present invention, from Table 1, one of the yarns constituting the knitting yarn is only a bare elastic yarn such as a polyurethane yarn, only a non-elastic yarn such as a nylon yarn, only a support yarn, and the elasticity of the bear. Any one of the alignment yarns of the yarn and the support yarn, or the alignment yarn of the bare elastic yarn and the inelastic yarn, and the other is only a plurality of bare elastic yarns, the bare elastic yarn and the inelastic yarn The knitting can be performed using a combination of any one of the yarns with the yarn and the yarns with the bare elastic yarn and the support yarn.

  Therefore, as an embodiment of the present invention, the “supporty yarn” in which the polyurethane yarn marked with “*” in Table 1 is covered with the nylon yarn and the polyurethane yarn and the nylon yarn are simply aligned. An example of knitting thick pantyhose using two types of yarns of “elastic yarn + inelastic yarn” on a knitting machine will be described.

  In the pantyhose according to the present invention knitted with the use of yarn as described above, the waist part and the panty part may have specifications of other knitting methods.

  FIG. 1 is an explanatory diagram showing an example of a knitting structure in which the stitches of stockings according to the present invention are forcibly slightly expanded. In FIG. 1, course 1 uses polyurethane elastic yarn 1 (core yarn) and support yarn 3 in which nylon inelastic yarn 2 is covered (single covering in the figure), and course 2 is polyurethane elastic yarn (one in the figure). 4 is used as a bear, and at the same time, a draw yarn 6 composed of a plurality of nylon inelastic yarns 5 (4 to 5 in the figure) is used. Then, the two types of knitting yarns are knitted while being simultaneously inserted into the knitting machine.

  When the bare polyurethane elastic yarn 4 of the aligning yarns 6 constituting one of the knitting yarns is inserted into the knitting machine, for example, by using a rolling feeder (yarn feeding device), the rotational speed of the rolling feeder is reduced. The polyurethane yarn 4 can be positively fed into the knitting machine while adjusting the tension. Unlike the support yarn that has already applied tension to the polyurethane elastic yarn at the time of covering, the tension of the polyurethane yarn 4 can be increased or decreased.

The stretch rate of the bare polyurethane elastic yarn 4 can be freely changed from 0% (when both rotation speeds are the same) by appropriately adjusting the rotation speed of the rolling feeder and the rotation speed of the knitting machine. It is possible.
For example, when the rotational speed of the knitting machine is constant, the lower the rotational speed of the rolling feeder, the stronger the tension of the elastic yarn and the higher the fit. In other words, different tension can be applied to the thigh, knee, calf, and ankle of the leg by changing the number of rotations of the rolling feeder. It is also possible to easily design by changing the wearing pressure stepwise by the vertical width, or gradually increasing the tension from the thigh to the ankle or from the calf to the ankle.

  2 is a photomicrograph showing the knitting structure of the stockings shown in FIG. 1, where course 1 in FIG. 2 means course 1 in FIG. 1, course 2 means course 2 in FIG. The polyurethane elastic yarn 4 is a bare polyurethane yarn 4 in the draw yarn 6 of FIG.

  In FIG. 1, the draw yarn 6 uses a nylon yarn 5 composed of one polyurethane elastic yarn 4 and 4 to 5 filaments. The denier and the number of filaments of the nylon thread 5 to be used are not particularly limited.

  1 and 2, nylon yarn 5 is used as an example of the aligning yarn 6, but this nylon yarn 5 may be a pre-dyed yarn, a post-dyed yarn, an original yarn, or an undyed yarn. It may be in a dyed state, and can be used regardless of dyeing, undyed or dyeing timing.

  The nylon inelastic yarn 5 of one knitting yarn in FIG. 1 is simply configured in the state of the aligning yarn 6, and is not in the state of being covered like the support yarn 1 of the other knitting yarn. If a thread is used, it will be in a state with a high freedom degree, Therefore It can be set as a highly soft goods.

  FIGS. 3A to 3C are image diagrams showing the difference between the conventional pantyhose and the pantyhose according to the present invention.

  FIG. 3 (a) shows a conventional zock knitted or cross knitted pantyhose, and the dimensions are changed by changing the size of the stitch while applying the same tension to the support yarn used. The thigh part has a large stitch, the ankle part has a small stitch, and the whole is tapered toward the toe part. Therefore, the flat dimension becomes smaller toward the ankle part.

  In Fig. 3 (b), the size of the thigh and ankle stitches is almost uniform, but only the tension of the polyurethane elastic yarn is controlled, the thigh is weak and the ankle is tight. Indicates that Compared to FIG. 3 (a), the product does not change much, so that the appearance of the product is less disturbed at the thigh and ankle.

  Further, FIG. 3 (c) further changes the size of the stitches in addition to FIG. 3 (a), the thigh part has a large stitch and the tension is weak, the ankle part has a small stitch and the tension is strong. Indicates that Thereby, it is possible to obtain a feeling of fitting and pressure that are higher than those of FIG. 3 (b), and the appearance is less disturbed than ordinary stockings, and the product is easy to wear.

  By adopting these designs, a new fit along the body, which is not found in conventional stockings, can be obtained, and a strong pressure value can be obtained by changing the stitches. Moreover, if it is a thick polyurethane elastic yarn, it can be a pressure stocking having a stronger feeling than ever before, and if it is a thin polyurethane, it can be a pressure stocking with transparency.
