Seamless socks and their manufacturing methods {Seamless socks and their manufacturing methods}

The present invention relates to 'seamless socks and a method for manufacturing the same' for improving wearing comfort by preventing a user from feeling pressure in the left and right directions by socks when a user wears socks.

As shown in FIG. 1, the conventional sock F manufactured using a circular knitting machine starts weaving from the ankle direction and is woven in a cylindrical shape in the toe direction. At this time, the gap between the toe part F3 and the instep part F4 is An open opening F1 is formed, and a seam line F2 is formed by sewing the open opening F1 in a separate sewing device.

As described above, the conventional socks (F) manufactured in a circular knitting machine have a sharp tip of the toe part (F3) and do not match the shape of the toe, so the toe is pressed in the left and right directions by the sock, and there is an uncomfortable feeling, and the toe part and the instep part There is a foreign body feeling due to the seam line F2 during the process of wearing socks or during wearing by the seam line F2 formed between the socks.

In addition, the lint generated from the conventional socks (F) is caught in the big toenail and causes an odor, which is inconvenient for hygiene management of the feet.

Republic of Korea Patent Registration No. 10-1299590 "Socks capable of distinguishing left and right" Korean Patent Publication No. 10-2022-0063916 "Double-sided circular knitting machine for producing circular knitted fabric having elastic yarn on the surface"

The present invention was created in order to more actively solve the above problems, and in the conventional socks (F), the tip of the toe part (F3) is pointed and uncomfortable wearing feeling caused by not matching the shape of the toe, and the toe part (F3 ) And the main problem is to solve the foreign body feeling caused by the seam (F2) formed between the instep (F4).

In addition, preventing the fluff generated from the conventional socks (F) from being caught in the toenail is another challenge.

In order to achieve the above problem, the composition of the seamless socks and their manufacturing method proposed by the present invention is as follows.

In the manufacturing method of the seamless socks of the present invention, the toe end 10, the toe part 20, the instep part 30, the heel part 40 and the ankle part 50 are formed using a flat knitting machine, In the manufacturing method of seamless socks in which the outer surface is woven so that the cotton yarn (T1) is visible and the inner surface is woven so that the span yarn (T2) is located, the center of the toe portion (20) forms a straight portion (21) in the form of a straight line. And, the outside where the thumb and little toe are worn is characterized in that it has a curved surface shape 22 that widens as it goes from the tip of the toe 10 toward the instep 30.

In addition, the polyurethane is melted and placed in a container (BT) with an open top, and the inside of the seamless socks manufactured by the manufacturing method of seamless socks is turned over so that the inner surface protrudes to the outside, and then the toe 20 is directed downward. The seamless socks are tilted at an angle (R) of 40 to 60 degrees from the surface of the polyurethane solution (P) contained in the container (BT), and then the thumb and little toe are alternately immersed in the polyurethane solution (P). It is characterized in that the sewing socks are taken out of the polyurethane solution (P) and dried to form the coating film (60).

According to the present invention composed of the above-described configuration, by forming the straight portion 21 at the center of the toe portion 20, there is an effect of relieving the pressure of the toe by socks.

In addition, by weaving the shape of the pattern (P) to be formed in the process of weaving the seamless socks using only the span yarn (T2) excluding the cotton yarn (T1), a separate thread to form the pattern (P) is required. It does not, and the thickness of the formed pattern (P) is thinner than the area where the span yarn (T2) and the cotton yarn (T1) are used together, so there is an effect of increasing air permeability.

In addition, by coating the thumb and little toe inside the seamless socks, there is an effect of preventing dirt from being caught between the big toenails due to fluff.

In the seamless socks of the present invention, the outer surface is made so that the cotton yarn (T1) is visible, and the inner surface is made so that the span yarn (T2) is located. The cotton yarn T1 makes the outer surface of the sock look smooth, and the span yarn T2 allows the sock to have elasticity so that the sock can stretch according to the size and shape of the user's feet.

Between the first and second needle beds B1 and B2, a first quadruple head H1 for supplying the span yarn T2 to the needle N and a second quadruple head for supplying the cotton yarn T1 to the needle N ( H2) is provided.

As shown in FIG. 8, the first and second quadruplets H1 and H2 reciprocate in the transverse direction and supply thread to the needles N of the first and second needle beds B1 and B2. The positions of the first and second quadruplets (H1, H2) are changed according to the direction of movement of the two quadruplets (H1, H2), so that the cotton yarn (T1) is located outside and the spandex yarn (T2) is located inside in the seamless socks It is made so that it is made.

To describe this in detail, referring to FIG. 8, when the thread is supplied to the needle N of the first needle bed B1, the second quadruped head H2 is located in the leading direction and the first quadruped head H1 is the second quadruped head. (H2) is followed. At this time, the angle (X1) formed between the cotton yarn (T1) supplied from the second quadruple head (H2) and the first needle bed (B1) is the span yarn (T2) supplied from the first quadruple head (H1). ) and the first needle bed (B1) is smaller than the angle (Y1) formed, the cotton yarn (T1) is located closer to the first needle bed (B1) than the span yarn (T2), and as shown in FIG. 9, the first Among the yarns supplied to the needles N of the needles B1, the cotton yarn T1 is supplied to the outside of the seamless sock and the span yarn T2 to the inside.

Contrary to the above, even when the thread is supplied to the needle N of the second needle bed B2, the second quadruped head H2 is located in the leading direction and the first quadruped head H1 follows the second quadruped head H2, The angle (X2) formed between the cotton yarn (T1) supplied from the second quadruple head (H2) and the second needle bed (B2) is the angle formed between the span yarn (T2) supplied from the first quadruple head (H1) and the first needle bed (B1). By being smaller than (Y2), the cotton yarn (T1) is located closer to the second needle bed (B2) than the span yarn (T2), and the cotton yarn among the yarns supplied to the needle (N) of the second needle bed (B2) (T1) is supplied so that the span yarn (T2) is located on the outside of the seamless sock and is located on the inside. The 'thread' described above refers to cotton yarn (T1) and spandex yarn (T2).

Referring to FIGS. 6 and 7, the process of weaving the yarn supplied to the needle N into a fabric or sock as above will be described. A protrusion N3 is formed at the lower end of the needle N, and the protrusion N3 is The needle (N) moves up and down.

Before the needle (N) rises, the thread (Z) is arranged around the lower part of the hook (N1) while forming a space inside the hook (N1) in the form of a ring, and the auxiliary needle (N2) is placed around the hook (N1). ) has a closed state of the opening (N1a).

And when the needle N rises to a certain height by the cam C, the auxiliary needle N2 is tilted by the thread Z inside the hook N1, and the opening part N1a of the hook N1 is opened. , When the needle (N) reaches the maximum height by the cam (C), the cotton yarn (T1) and the span yarn (T2) are located inside the hook (N1).

Then, when the needle (N) descends by the cam (C), the auxiliary needle (N2) is tilted by the thread (Z) located at the lower end of the auxiliary needle (N2), and the opening (N1a) of the hook (N1) is closed, and when the needle (N) is further lowered by the cam (C) in the above state, the hook (N1) passes through the inside of the thread under the auxiliary needle (N2) and comes out downward.

And, as above, after the hook (N1) passes through the inside of the thread (Z) under the auxiliary needle (N2), the thread (Z) under the auxiliary needle (N2) descends downward due to its own weight, and the needle ( When N) is raised again by the cam C, the yarn inside the hook N1 moves to the upper side of the yarn under the auxiliary needle N2, forming one stitch. Here, 'ko' refers to a loop formed by intertwining threads. When weaving by repeating the above method, the yarn is woven as shown in FIG. 10 to have the form of a fabric.

Referring to FIGS. 3 and 4, the sequence of weaving seamless socks using the above-described method is described by forming a nose on the needles N of the first and second beds B1 and B2 as a starting step to toe the toes. It is woven from the part corresponding to the end 10.

The length formed in the width direction of the toe end 10 can be formed with a length of 80 to 90 mm and 64 to 72 noses for adults, and a length of 60 to 70 mm and 48 to 56 noses for infants. there is. The horizontal length of the toe end 10 formed at the beginning of the above is applied equally to the maximum length of the toe part 20 and the instep part 30, the heel part 40 and the ankle part 50.

After weaving the toe end 10, the toe part 20 is woven. The center of the toe part 20 forms a straight line part 21 in the form of a straight line, and the outside where the thumb and little toe are worn is the toe end. In (10), it is woven to have a curved surface shape (22) that becomes wider in the direction of the instep portion (30).

The straight part 21 at the center of the toe part 20 can be formed with a length of 45 to 55 mm and 35 to 45 noses for adults, and a length of 35 to 45 mm and 28 to 36 noses for infants. . In addition, the vertical length of the toe may be formed in a length of 26 to 34 mm and 26 to 34 stages for adults, and may be formed in a length of 16 to 24 mm and 16 to 24 stages for infants. A hem here refers to a longitudinal layer of yarn being woven.

In the conventional sock (F) woven by a circular knitting machine, the toe portion (F3) is sharp and does not match the shape of the toe, so the toe is pressed by the sock in the left and right directions, so there is an uncomfortable feeling. In the present invention, the toe portion (20 ) By forming the straight portion 21 at the center of the sock, the pressure of the toe due to socks was eliminated.

In addition, since the seam line (F2) formed between the toe part 20 and the instep part 30 in the conventional socks (F) disappears in the seamless socks, the feeling of foreign matter due to the seam line (F2) during the process of wearing the socks or wearing them be able to resolve

Following the toe part 20, the instep part 30 is woven. Since the center of the sole of the person's sole is arched, as shown in FIG. , The rubber thread (T3) was inserted between the front and rear surfaces of the nose composed of the cotton thread (T1) and the spandex thread (T2).

As described above, in order to weave the rubber thread T3, the flat knitting machine H includes a third quad (not shown) for supplying the rubber thread T3 to the needle N.

The vertical length of the instep portion 30 may be formed in a length of 165 to 175 mm and 132 to 140 stages for adults, and may be formed in a length of 55 to 65 mm and 44 to 52 stages for children.

Since infants have small feet and the arch shape of the sole is not clear, it is preferable to apply the above rubber thread (T3) only to adult seamless socks, and the place where the rubber thread (T3) is applied to adult seamless socks is the toe area. It can be formed in a section of 30 to 40 mm (24 to 32 steps) at a location 80 to 90 mm (64 to 72 steps) away from (20).

After weaving the instep portion 30, the heel portion 40 is woven. The instep side of the seamless socks is woven on the first needle B1 and the sole side of the seamless socks is woven on the second needle B2. If so, the heel portion 40 is woven only on the second needle bed B2, and during the weaving process of the heel portion 40, the weaving operation is stopped on the first needle bed B1.

As shown in FIG. 4, the heel portion 40 is woven so that the width is narrowed in an oblique direction in the direction of the ankle portion 50, and then the width is increased in an oblique line again at the center of the heel 41 and then reduced again. ) direction, the heel portion 40 is woven so that the heel portion 40 has a three-dimensional effect.

In the process of weaving the heel part 40, the angle of the oblique line is 45 degrees, and the maximum horizontal width 41b of the heel center 41 is 42 to 48 mm (33 to 38 nose) for adults and 32 to 48 mm for children. 38m (25-30 nose), and the minimum horizontal width (41c) of the center of the heel 41 is 32-38mm (25-30 nose) for adults and 22-28mm (17-22 nose) for children. can be weaved

After weaving the heel portion 40, the ankle portion 50 is woven. The instep surface of the ankle portion 50 extends from the instep portion 30, and the sole surface of the ankle portion 50 is heel ), and weaving takes place.

As shown in FIG. 11, at the tip of the ankle part 50, the rubber thread T3 is inserted between the front and back surfaces of the nose made of the cotton thread T1 and the spandex thread T2, so that the ankle part when the user wears seamless socks (50) is made to hold tightly so that it does not flow down.

The total length of the ankle portion 50 may be formed to be 60 to 70 mm (60 to 70 steps) for adults and infants, and the portion where the rubber thread T3 is formed is 22 to 30 mm from the upper end of the ankle portion 50. (22 to 30 stages) can be formed.

In another embodiment, as shown in FIG. 12, the pattern P can be formed on the instep part 30 and the ankle part 50 of the seamless socks, which are seamless using span yarn T2 and cotton yarn T1. In the process of weaving socks, the pattern P of socks can be formed by weaving the shape of the pattern P to be formed using only the span yarn T2 excluding the cotton yarn T1.

As a method for weaving it, the first quadruple head H1, which supplies the span yarn T2 to the needle N, moves reciprocally without stopping in the transverse direction, but the cotton yarn T1 is supplied to the needle N. The second quadruped head (H2) stops before reaching the area where the pattern (P) is to be formed, and then the needle (N) receives the span yarn (T2) supplied from the first quadruple head (H1) and then moves, thereby creating The pattern P can be formed.

The advantage of the above method is that a separate thread to form the pattern (P) is not required, and the thickness of the formed pattern (P) is thinner than the area where both the span yarn (T2) and the cotton yarn (T1) are used, improving air permeability. can be raised

In the conventional socks (F), the lint generated in the socks is caught in the big toenail and causes an odor. In order to solve this problem, in the other embodiments of FIGS. Forming a seamless sock and presenting a method of manufacturing the same to prevent dirt from being caught between the user's toenails due to fluff generated from the seamless sock.

Since the seamless socks of the present invention do not distinguish between the direction of wear of the thumb and the little toe, both the thumb and the little toe of the inner surface of the seamless socks are coated because they can be worn for both left and right use.

If the coating is applied between the thumb and the little toe, it is emphasized that only the thumb and the little toe should be coated because the elasticity of the toe 20 is reduced due to the coating, resulting in poor wearing comfort.

Polyurethane (PU) can be used as the coating solution, and the polyurethane is melted, put in a container (BT) with an open top, turned over so that the inner surface of the seamless socks protrudes to the outside, and then the toe 20 faces down. face, and incline the seamless sock at an angle (R) of 40 to 60 degrees from the oil surface of the polyurethane solution (P) contained in the container (BT), and then place the thumb and little toe alternately in the polyurethane solution (P). After soaking for ~3 seconds, take the seamless sock out of the polyurethane solution (P) and dry it.

The depth of the toe 20 immersed in the polyurethane solution P may be 15 to 30 mm, and as above, when the toe 20 is immersed in the polyurethane solution P for 2 to 3 seconds, the coating film 60 ) is formed at a thickness of 0.5 to 1 mm.

After drying the seamless socks coated with the toe part 20 as described above, turning them over so that the outer surface faces the outside, and then ironing and packaging, the product can be sold, and the coating film on the thumb and little toe on the inside of the seamless socks By forming 60, it is possible to prevent dirt from being caught between the big toenails due to fluff.

The present invention described above has been described with reference to one embodiment shown in the drawings, but this is only exemplary, and those skilled in the art can make various modifications and equivalent other embodiments therefrom. will have to be clarified. Therefore, the true technical protection scope of the present invention should be construed by the appended claims, and all technical ideas within the equivalent range should be construed as being included in the scope of the present invention.
