Description

  The present invention relates to socks such as socks and stockings that are knitted by a sock knitting machine, and particularly to socks that are characterized by the configuration form of the buttock and a method for manufacturing the same.

  For example, socks such as socks and stockings (including pantyhose) are dedicated sock knitting machines using a circular knitting machine, that is, a cylindrical cylinder capable of rotating forward and reverse, in which a large number of knitting needles are arranged to be movable up and down. For example, in the case of socks, it is composed of an upper end opening, a leg part, a heel part, an instep part, a sole part, and a toe part. Patent Document 2).

  In the sock knitting, the leg part 22, the heel part 23, the instep part 24, the sole part 25, and the toe part 26 are usually knitted in this order from the side of the opening part 21 which becomes the sock's wear mouth shown in FIG. Therefore, the boundary part between the leg part 22 and the collar part 23 is knitted into a cylindrical shape by one-direction rotation (forward rotation) of the cylinder. In the collar part 23, following the leg part 22 The knitting needle is held so as not to perform knitting in the rotational angle range (about half a circle) on the side where the instep part 24 is knitted, and the cylinder is moved by the knitting needle for about a half circumference on the side where the heel part 23 is knitted. Each course is reciprocally rotated (reversed) in the opposite direction to perform so-called reversal knitting, and knitted so as to give the necessary bulge as the buttock 23. At this time, in order to maintain the strength as the heel portion 23, the knitting portion 23 is usually knitted by switching the knitting yarn to another strong yarn. Then, when the knitting of the heel part 23 is completed, the knitting yarn is switched to the original knitting yarn, and the instep part 24 continuous to the leg part and the sole part 25 continuous to the heel part 23 are formed into cylinders by forward rotation of the cylinder. And the toe portion 26 is further knitted, and finally the opening of the toe portion 26 is closed to complete the knitting.

As described above, in the conventional knitting under the socks, the heel portion is formed by the reverse knitting by reciprocating rotation of the cylinder, and the yarn needs to be switched. Due to the switching of the yarn material, there is a possibility that stitching, transmission lines, etc. may occur in the knitting, resulting in a hindrance to productivity. Further, a color difference due to the difference in the thread material occurs between the leg part and the heel part, and the appearance becomes unnatural, and the joints 27 and 28 are formed by switching the thread material at the boundary part between the heel part, the leg part, and the sole part. This part becomes weak and is likely to be unraveled, and there is a problem in durability in use.
Registered Utility Model No. 3058883 Registered Utility Model No. 30613334

  The present invention was made in order to solve the problems caused by the reverse knitting at the heel and the switching of the yarn in the conventional knitting under the socks, and the entire knitting requires the reverse knitting with the same knitting yarn of the same or a plurality of combinations. By knitting continuously into a cylindrical shape, it is possible to form a ridge that forms a bulge shape, and there are few missing stitches or wires on the knitting, and the knitting efficiency can be improved. The present invention provides a sock that has good integration with other parts such as legs and the like, has no noticeable color difference, has excellent appearance and durability, and a manufacturing method that can efficiently produce the sock.

  The socks of the present invention for solving the above-mentioned problems are formed by continuously knitting the leg part, the heel part, the instep part and the sole part in the sock so that the leg part, the instep part and the sole part. At least the area around the buttocks is knitted with a knitting structure having a large contraction, and the buttock is knitted with a knitting structure having a smaller contraction than the knitting structure in the area around the buttocks The ridge is provided with a bulge. Usually, the leg part, the buttocks part, the instep part, and the sole part are continuously knitted with the same knitting yarn by the same or plural combinations.

  According to the socks of the present invention, although the whole from the leg part to the instep part and the sole part, particularly the whole including the heel part is continuously knitted in a cylindrical shape, The heel part of the knitted structure having a small shrinkage in structure is swelled compared to the area around the heel part of the knitting structure having a larger shrinkage than this, and the heel part by the conventional inverted knitting in terms of appearance and strength. An inferior collar part is formed.

  In addition, on the knitting under the socks, it is not necessary to switch the reverse knitting and the yarn that rotate the knitting machine cylinder backward, and the buttock can be easily knitted only by changing the knitting structure. For this reason, there is no seam due to the switching of the thread at the boundary between the heel part, the leg part, and the sole part, there is no risk of breakage or transmission on the knitting and unraveling in use. There is no noticeable color difference between the part and the other part due to the difference in the thread material.

  In the socks, it is preferable that the heel portion is knitted with a boss yarn separately from the knitting yarn for knitting the leg portion, the heel portion, the instep portion, and the sole portion for each one or a plurality of courses. . In this case, the collar portion can be reinforced by the boss thread, and the strength of the collar portion can be increased.

  Further, in the above socks, the knitting structure in at least the area around the heel part in the leg part, the instep part and the sole part is a knitting structure in which a plurality of convex parts by continuous float knitting of a plurality of courses are formed at every required interval. It can be assumed that Accordingly, at least the region around the heel portion can be greatly contracted, and the bulge shape of the heel portion can be more clearly revealed.

  The sole has a knitted structure in which a number of convex portions in the circumferential direction by continuous float knitting are formed in parallel, and the number of courses of the continuous float knitting that forms the convex portions of the sole is 3 to 3. It is preferable that there are 25 courses. Thereby, the convex part by the said continuous float knitting can be formed comparatively large, and the shrinkage | contraction in a knitting up state becomes large, and while providing the acupressure massage effect with respect to a sole, the said convex part also exhibits the effect of a non-slip. Become a thing.

  In the sole part, one or a plurality of courses are preferably formed by knitting boss yarn separately from the knitting yarn knitting the leg part, the heel part, the instep part and the sole part, While being able to reinforce the sole, it is possible to impart moderate hardness to the convex portion and further enhance the acupressure massage effect and anti-slip effect. Various functions can be given by selecting the material of the boss yarn. For example, an antibacterial and deodorizing function can be imparted by using an antibacterial deodorizing yarn.

  In the socks, it is preferable that the knitting yarn knitting the leg part, the heel part, the instep part, and the sole part is made of an elastic thread, which can give stretchability to the entire sock and fit at the time of wearing. And good holding pressure.

  Further, in the present invention, as a method for manufacturing the socks, in the knitting of the socks by the sock knitting machine, the heel part, the instep part and the sole part are continuously knitted in a cylindrical shape from the leg part of the socks. And knitting at least the area around the heel part of the leg part, the instep part and the sole part with a knitting structure having a systematic contraction larger than that of the heel part. A bulge is imparted to the buttocks by knitting with a knitted structure having a smaller contraction in terms of structure.

  As a result, the sock with the swollen portion of the heel portion can be easily and efficiently knitted by the sock knitting machine without reverse knitting at the heel portion and without switching the yarn.

  According to the sock and the method of manufacturing the same of the present invention, the entire knitting can be formed into a tubular shape by continuously knitting the same knitting yarn into a tubular shape without requiring reverse knitting and without requiring yarn switching. The part can be easily formed, and there are few drop-offs or wires on the knitting, so that the knitting efficiency can be improved. Furthermore, as described above, the thread does not need to be switched, so that the heel part and the leg part and other parts are well integrated, and there is no noticeable color difference. Socks with excellent appearance and durability. Can improve the productivity of this type of socks.

  Next, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is a schematic side view showing a sock of an embodiment of the present invention, FIG. 2 is a schematic front view seen from the side of a sole of the same sock, and FIG. 3 is a region around a heel part of the sock of the present invention. An enlarged organization chart is shown. FIG. 4 is a schematic side view showing another embodiment. FIG. 5 is an explanatory view of the structure of the continuous float knitting, and FIG. 6 is an explanatory view of the structure when the boss yarn is knitted.

  The sock A in the illustrated embodiment shows the case of socks. In the figure, reference numeral 1 is an opening at the upper end that becomes a wearing mouth, 2 is a leg part, 3 is a heel part, 4 is an instep part, and 5 is a foot part. The back part and 6 have shown the toe part.

  This sock A is basically made of a sock knitting machine using a circular knitting machine in the same manner as in the past, and from the opening 1 side, the leg part 2, the heel part 3, the instep part 4 and the sole. The part 5 and the toe part 6 are sequentially knitted, but particularly in the case of the present invention, even in the knitting of the collar part 3, the leg part 2, The entire heel part 3, the instep part 4 and the sole part 5 are continuously knitted in a cylindrical shape with the same knitting yarn by one or a plurality of the same or a plurality of combinations, for example. Usually, an elastic yarn is used for the knitting yarn as described later.

  And in order to form the said heel part 3 so that a predetermined bulge shape may be formed, in the present invention, at least the above-mentioned buttock peripheral region in the above-mentioned leg part 2, instep part 4 and sole part 5, for example as shown in the figure In addition, the entire area of the leg part 2, the instep part 4 and the sole part 5 is knitted with a knitted structure having a large contraction systematically apart from the contraction due to the elasticity of the yarn material, and the heel part 3 The knitting structure is knitted with a plain knitting structure whose shrinkage is smaller than that of the knitting structure in the peripheral region, and is usually a flat knitting structure which hardly shrinks systematically. A bulge is given.

  The said heel part 3 shall have the area which can foreput at least the sole side of a heel at the time of wear, Preferably it has the area which can be foreseen from the sole side to the heel vicinity, The shape is a substantially ellipse like a figure, for example The present invention is not limited to the shape, and various shapes corresponding to the shape of the ridge can be used. Usually, the sole portion 5 is continuously formed from the heel portion 3 as shown in the figure. The heel part 3 can be knitted only with the knitting yarn knitting the entire socks, but in practice, a boss yarn is provided separately from the knitting yarn for one or a plurality of courses, preferably for each course. It is preferable that the cut boss is knitted by a technique such as a spliced yarn to reinforce the collar portion 3. FIG. 5 shows an example of the knitting of the boss yarn. The knitting yarn Y1 of the knitting structure as a base is knitted by a knitting yarn knitting method using another boss yarn Y2 as a cut boss, The end Y2a of the boss yarn Y2 is cut to a required length and left on the back side (inner side of the sock) of the knitted fabric.

  The knitted structure having a large shrinkage in the structure may be any knitted structure as long as the knitted structure is contracted more greatly than the heel part 3 of the knitted structure having a small shrinkage in the knitted up state. However, in practice, a large number of convex portions 7 and 8 formed by a continuous float knitting as illustrated in FIG. 6, that is, a continuous float knitting portion 11 that forms a multi-course welt loop 11 a is formed at every required interval. Thus, a knitted structure having unevenness which is contracted is preferable.

  For example, as the knitted structure having a large shrinkage of the leg portion 2 and the instep portion 4, a continuous float knitting in which a welt loop having a plurality of courses, preferably 2 to 20 courses, is formed for each required course based on a flat knitting. Are formed in a structure in which the portions are arranged at an appropriate interval in the knitting width direction, and a plurality of convex portions 7 having a hook shape in the circumferential direction are formed by shrinking the continuous float knitting portion in the knitting direction after knitting. The knitting structure is uneven. In this case, the convex part 7 can stimulate a wearer's leg and can exhibit a shiatsu massage effect, and can also exhibit effects such as elimination of swelling of the leg. In the organization chart of FIG. 3, reference numeral 11 denotes a continuous float knitting portion that forms the convex portion 7 in the leg portion 2 and the instep portion 4, and 12 denotes a flat knitting portion.

  The convex portion 7 does not necessarily have a hook shape that is linearly continuous in the circumferential direction, and is a convex portion that is continuous in a wavy shape in the circumferential direction, a convex portion that forms an oblique hook shape, and a circumferential direction. It is possible to implement with various types of convex portions, such as intermittent convex portions, convex portions arranged in a staggered manner, or a combination of these convex portions. Further, the convex portion 7 is not necessarily formed uniformly over the entire area of the leg portion 2 and the instep portion 4. For example, as in the example of FIG. What is necessary is just to arrange | position at least the peripheral region of the said collar part 3, such as forming.

  In the knitting direction for tubular knitting, the heel portion peripheral region is a region having a course range slightly wider than the heel portion 3 as shown in the example of FIG. 4, and the heel portion 3 and the heel portion 3 It is assumed that the range 9 includes the instep part 4 on the opposite side, and the bulge can be contracted in the heel part 3 by the contraction of the range 9.

  In addition, as the knitted structure having a large shrinkage of the sole 5, for example, a continuous loop in which a welt loop of 3 to 25 courses is formed for each required course on the basis of a flat knitting as in the leg 2 and the like. In the structure in which the float knitted portions are arranged at an appropriate interval, the continuous float knitted portion shrinks in the knitting direction after knitting, so that the wrinkles in the circumferential direction are slightly higher than the convex portions 7 such as the leg portions 2. A knitted structure having irregularities formed by forming convex portions 8 having a shape. In this case, the slightly higher convex portion 8 stimulates the soles of the wearer, and has an effect of relieving fatigue by exerting a massage effect like a good bamboo stepping. In the organization chart of FIG. 3, reference numeral 13 denotes a continuous float knitting part that forms the convex part 8 in the sole part 5, and reference numeral 14 denotes a flat knitting part.

  The convex portion 8 of the sole 5 is not limited to a linearly continuous ridge shape in the circumferential direction, but also has a wavy shape in the circumferential direction, an oblique ridge-shaped convex portion, or an intermittent convex shape. It is possible to implement with various types of convex portions, such as a portion, convex portions arranged in a staggered manner, or a combination of these convex portions. The convex portion 8 does not necessarily have to be formed in the entire area of the sole portion 5, and may be partially formed. If the convex portion 8 is arranged at least in the peripheral region name of the heel portion 3. Good.

  As with the heel part 3, the sole part 5 is separated from the base and the knitting yarn of the knitting structure for each course, preferably for each course, as in the case of the heel part 3 described above. A boss yarn (not shown) having a function different from that of the knitting yarn is preferably knitted. That is, the sole 5 can be reinforced by the boss thread, the acupressure massage effect and the anti-slip effect by the protrusion 8 can be enhanced, and various functions can be given by the boss thread. By using an antibacterial deodorizing yarn, an antibacterial and deodorizing function can be imparted.

  The foot sole 5 substantially corresponds to the portion other than the area of the heel portion 3 and the toe portion 6 on the sole side, and may be substantially the same width as the sole side. In the case of the example, the convex portion 8 is formed and / or the boss yarn is knitted, and the region where the knitted structure is changed from the instep portion 4 side is set slightly narrower than the width on the sole side, and further, the sole The side closer to the toe portion 6 is set to be slightly wider so as to correspond to the shape of.

  In addition, although not shown in the figure, in the region of the heel part 3, a float knitting that plays a role of buffering tissue change in a band along the inner side of the boundary with the other part such as the leg part 2 and the instep part 4. It can be carried out by interspersing.

  As the knitting yarn used for the socks A, an elastic yarn such as a single covered yarn or a double covered yarn in which a nylon filament is covered with a polyurethane elastic yarn is preferably used. By using an elastic yarn, the entire sock can be moderately stretched, and the fit and wearing pressure during wearing can be maintained well. The thickness of the elastic yarn to be used can be appropriately set according to the mode of the socks to be manufactured, and for example, a yarn of 40 to several hundred dtex is used.

  As described above, the sock A of the present invention is a normal knitting which is rotated in the same direction of the knitting machine cylinder in the sock knitting by the sock knitting machine, and the whole is continuously knitted in a cylindrical shape with the same knitting yarn. In addition, as described above, at least the area around the heel part of the leg part 2, the instep part 4 and the sole part 5 is knitted with a knitted structure having a texture and having a large shrinkage, and the heel part 3 The knitting structure is knitted with a knitting structure whose shrinkage is smaller than that of the knitting structure in the peripheral region of the hip, for example, a flat knitting structure.

  For this reason, in spite of the fact that the entire body including the heel part 3 is continuously knitted in the shape of a cylinder with the same knitting yarn, in the knitted up state, the heel part 3 of the knitted structure with small structural shrinkage is A bulge shape is formed as compared with the peripheral region of the heel portion of the knitted structure having a larger shrinkage than this, and the heel portion 3 is formed which is not inferior to the heel portion of the conventional inverted knitting in appearance and strength. Moreover, on the knitting of the socks A, it is possible to easily form the knitted portion 3 by simply changing the knitting structure without the need for reversal knitting and yarn switching by reciprocating rotation of the knitting machine cylinder in order to form the collar portion 3. , There is no seam due to the switching of the thread at the boundary between the heel part 3 and the leg part 2 or the sole part 5, there is no risk of breakage or transmission on the knitting, and unraveling in use. No noticeable color difference due to the difference in the yarn material occurs between 3 and other parts. Therefore, it is possible to obtain socks that are excellent in appearance and durability, and it is possible to improve the productivity of this type of socks.

  The present invention can be suitably used for various socks such as stockings including socks and pantyhose.
