Abstract

<P>PROBLEM TO BE SOLVED: To provide a production method capable of imparting a desired function, e.g. a non-slip function to only necessary places of hosiery. <P>SOLUTION: When knitting the hosiery by a circular knitting machine, a functional area is formed at a part in the peripheral direction of the hosiery by weaving a functional yarn different from a knitting yarn of the hosiery by utilizing a reciprocating rotating function of the circular knitting machine. The functional area is preferably formed by weaving the functional yarn so as to constitute substantially the same face as the peripheral part or adjacent part. Areas (20, 21, 22, 23 and 24) having a non-slip function can be formed in a plantar part, a part adjacent to the plantar part of heel or a part adjacent to the plantar part of tiptoe by weaving the functional yarn having the non-slip function. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a method for manufacturing socks, for example, a method in which a non-slip function can be imparted to a sole portion of socks by a knitting structure.

  For example, when wearing socks or stockings (hereinafter simply referred to as “socks”) and wearing sandals or shoes, depending on the type of knitting yarn, it may be difficult to walk because the soles may slip. Desired.

  Therefore, socks have been proposed in which polyurethane resin or silicon resin is dispersed and fixed to the sole portion in a dotted manner (Patent Document 1, Patent Document 2, Patent Document 3). In addition, socks have been proposed in which a heel part or a sole part is impregnated with polyurethane resin or vinyl chloride resin, or a film of polyurethane resin or vinyl chloride resin is adhered (Patent Document 4, Patent Document 5). .

  However, in the socks described in Patent Documents 1 to 5, since the protrusions are dispersed on the soles of the socks, it is easy to feel uncomfortable, and it is necessary to perform non-slip treatment after knitting the socks. The number of processes increases, and it is necessary to perform post-processing using a polyurethane resin or silicon resin, resulting in high costs.

  In view of such problems, the present invention provides a method of manufacturing socks that can form a region having a necessary function, for example, a region having a non-slip function, in a necessary part while maintaining an excellent feeling of touch. This is the issue.

  Therefore, in the method of manufacturing socks according to the present invention, when knitting socks by knitting yarn with a circular knitting machine, the socks are revolved in the circumferential direction of the socks using the reciprocating rotation function of the circular knitting machine. A functional region is formed by knitting a functional yarn different from the knitting yarn.

  One of the features of the present invention resides in that a functional region is formed by knitting functional yarns in a part of the circumferential direction of socks using the reciprocating rotation function of the circular knitting machine. This makes it possible to form necessary functional areas such as soles, heels or toes, for example, functional areas having a non-slip function, and processing resin such as polyurethane and silicon as in the past. Therefore, the excellent feel of the whole socks will not be impaired. The present invention has a great effect when applied to socks, but some recent stockings are manufactured by the same knitting method as socks, and such stockings can be similarly applied.

  The reciprocating rotation function of the circular knitting machine is a function used when knitting the sock's heel part or toe part part, using a part of the needle in the circumferential direction of the cylinder, rotating the cylinder forward by an arbitrary angle, rotating it backwards, By repeating this forward and reverse rotation, the heel part and the toe part are knitted in a half bag shape. The circular knitting machine may be either a single cylinder type or a double cylinder type.

  If the reciprocating rotation function of the circular knitting machine is simply used, the functional area swells round compared to the adjacent part. The soles of humans are very sensitive, and very small pebbles are covered with the soles of socks, and even if they hit the soles, they feel uncomfortable and painful. Therefore, if a functional area with a bulge is formed on the sole part of the socks, the part adjacent to the sole part of the heel part, or the part adjacent to the sole part of the toe part, the person wearing the socks feels uncomfortable. There is a fear.

  Therefore, it is preferable to form the functional region by knitting functional yarns different from the knitting yarns of the socks so as to constitute substantially the same surface as the surrounding portion or the adjacent portion. Thereby, the possibility of giving a sense of incongruity to a person wearing socks can be reduced.

  Here, when the functional area is knitted on the same surface as the surrounding part or the adjacent part using the reciprocating rotation function of the circular knitting machine, the surrounding part or the adjacent part is changed depending on the size of the socks or the type of knitting yarn used. It may swell a little compared. The “same surface” in the claims includes not only a geometrically identical surface, but also a substantially identical surface slightly expanded as described above (hereinafter, for convenience of explanation, simply “ "Substantially the same surface").

  In order to use the reciprocating rotation function of the circular knitting machine to form the functional area on substantially the same surface as the surrounding or adjacent portion, the number of stitches is gradually increased or decreased gradually, for example, every two courses. It is necessary to devise such as gradually increasing or decreasing one eye or two eyes, or forming a functional area extending in the width direction in the sole part, the heel part, or the toe part. It is necessary to select appropriately according to the size. For example, in the case of women's socks, the functional region can be configured on the substantially same surface as the surrounding portion or the adjacent portion by knitting the functional region into a shape as shown in FIG. Of course, even if other shapes are adopted by devising the increase / decrease of the stitches, the functional region can be formed on the substantially same surface as the surrounding or adjacent portion.

  The functional yarn may be knitted instead of the sock knitting yarn, or may be knitted together with the knitting yarn. If the non-slip area is formed by using a thread having a non-slip function, for example, a covering thread using polyurethane as a core thread, preferably a nylon-wrapped polyurethane thread or a polyester-wrapped polyurethane thread wound with nylon or polyester. Although the effect is great, of course, other functional yarns such as a functional yarn having a deodorizing function, a sterilizing function or an aroma function can also be adopted.

  The functional region, for example, the non-slip region, is preferably formed in the sole portion. In this case, one non-slip region or a plurality of non-slip regions can be formed.

  Further, the non-slip region may be formed not only at the sole portion but also at a portion adjacent to the sole portion of the heel portion or a portion adjacent to the sole portion of the toe portion.

  There are no particular restrictions on the material of the hosiery knitting yarn, and it is used in socks such as cotton yarn, cotton acrylic blended yarn, wool yarn, wool acrylic blended yarn, silk yarn, silk acrylic blended yarn, hemp yarn, hemp acrylic blended yarn, nylon yarn, etc. Can be used. The knitting structure of the socks is not particularly limited, and plating knitting and flat knitting can be adopted. Moreover, socks can be knitted by combining knitting yarn and elastic yarn. As the elastic yarn, rubber yarn, nylon yarn, polyester yarn, polyurethane covered yarn, and core yarn can be used.

  The functional region only needs to be formed in a part of the socks in the circumferential direction. For example, the functional region may be formed so as to extend over the entire width of the sole, heel, or toe of the socks. You may make it extend and form a part.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 5 show a preferred embodiment of a method for manufacturing socks according to the present invention, which is an example applied to socks. The sock 10 basically includes a cuff portion 11, a leg portion 12, a foot portion 13, a sole portion 14, a heel portion 15, and a toe portion 16.

  The sock 10 is knitted using, for example, a single cylinder type circular knitting machine, and is knitted in a cylindrical shape from the cuff portion 11 toward the tip side of the instep portion 13 and the sole portion 14, and the heel portion 15 and the toe portion 16 are round. Knitted by the reciprocating rotation function of the knitting machine, and the opening between the terminal edge of the toe portion 16 and the tip edge of the instep portion 13 is sewn by linking or Rosso (17 in FIG. 1 is a sewing location). .

  Further, the sole portion 14 is formed with a non-slip region 20 extending to the entire width, and the non-slip regions 21 and 22 are formed extending partly in the width direction. Non-slip regions 23 and 24 are formed to extend to the full width at adjacent portions and portions adjacent to the sole portion 14 of the toe portion 16.

  The anti-slip regions 20 to 24 use the reciprocating rotation function of the circular knitting machine, and instead of the knitting yarn of the sock 10, the functional yarn having the anti-slip function is knitted so as to constitute substantially the same surface as the adjacent portion. Can be organized.

  Next, a manufacturing method will be described. The circular knitting machine is provided with a needle hook (cylinder) 30 shown in FIG. 3, and around the needle hook 30, a large number of knitting needles (needles) 31, for example, 220 knitting needles 31, are supported in a vertically movable manner. 30 is rotated in the forward direction (forward rotation) and rotated in the reverse direction (reverse rotation), the knitting needle 31 is lifted at a predetermined rotational position, and the knitting yarn is hooked to perform knitting.

  When the sock of this example is manufactured by the circular knitting machine, the sock 10 is first knitted in a cylindrical shape from the cuff portion 11 toward the toe portion 16, and at that time, the needle hook 30 is rotated forward 360 ° (in FIG. 4). (See (a) (e)).

  When the sock 10 is knitted into a cylindrical shape, the needle hook 30 is rotated forward and reverse by the reciprocating rotation function of the circular knitting machine when it reaches the heel part 15 (FIGS. 4B, 4C, and 4D). For example, after the forward rotation and the reverse rotation are repeated, the number of knitting needles 31 to be used is reduced to 110 to 64, for example, and then increased to 64 to 106, and a half bag-like portion is knitted. The heel part 15 is knitted.

  Similarly, when reaching the toe portion 16, the needle hook 30 is repeatedly rotated forward and backward by the reciprocating rotation function, and for example, the number of knitting needles 31 to be used is reduced to 110 to 64, and the knitting needles 31 are continuously moved. The toe portion 16 is knitted by this, and the opening between the terminal edge of the toe portion 16 and the tip edge of the instep portion 13 is sewn by linking or Rosso.

  When knitting the heel part 15, the sole part 14, and the toe part 16 as described above, the reciprocating rotation function of the circular knitting machine is used, and the functional yarn is used instead of or together with the knitting yarn of socks. For example, nylon-wrapped polyurethane yarn is used, and the non-slip regions 20 to 24 are formed by knitting so as to constitute substantially the same surface as the surrounding portion or the adjacent portion. For example, in the case of the non-slip region 20, the number of knitting needles 31 to be used is increased from 84 to 109 every 2 courses from 84 to 2 after every 109 courses. By reducing the number to 84 at a time, it is possible to configure the surface substantially the same as the surrounding portion or the adjacent portion. In the first course and the last course, the stitches are almost halved due to the relationship between the knitting start position and the knitting end position of the needle hook 30.

  Further, in the case of the non-slip regions 21 and 22, it is smaller than the non-slip region 20, but it can be configured on the same surface as the surrounding part or the adjacent part by making it similar to the non-slip region 20. it can.

  Further, in the case of the non-slip regions 23 and 24, by adopting the half shape of the non-slip region 20, it is possible to configure the same part as the surrounding part or the adjacent part. In the case of the non-slip regions 20 to 22, the shape shown in FIG. 5 or a similar shape is used in order to ensure a large length in the front-rear direction. The same shape as 23 and 24 can be adopted.

  As described above, using the circular knitting machine and utilizing the reciprocating rotation function used when knitting the heel part 15 and the toe part 16, the anti-skid regions 20 to 24 are knitted. The regions 20 to 24 can be knitted on substantially the same surface as the surrounding portion or the adjacent portion, and the excellent feel of the entire socks is not impaired.
