Description

TECHNICAL FIELD The present invention relates to a tubular knitted fabric having a non-slip portion formed by exposing a high-friction material, and a method for manufacturing the same.

Tubular knitted fabrics such as socks and gloves are sometimes provided with a non-slip portion that has a non-slip function against the wearer's skin, external shoes, objects held, etc.
As a conventional tubular knitted fabric having a non-slip part, there is one in which the knitted fabric is coated with a high-friction material such as silicone rubber to give the non-slip part an anti-slip function (for example, Patent Document 1 )

Japanese Patent Application Publication No. 2014-43662

Conventionally, when coating a knitted fabric with a high-friction material to provide an anti-slip function to the anti-slip part, a relatively complicated coating process is required, making it difficult to reduce the cost of tubular knitted fabric products. It becomes an inhibiting factor. Furthermore, since the thickness of the coated portion coated with the high-friction material is larger than that of the surrounding area, unevenness occurs in the knitted fabric, and these unevenness become a factor that impairs the wearing comfort of the wearer.

In view of this situation, the main object of the present invention is to provide a cylindrical knitted fabric having a non-slip part made of exposed high-friction material and a method for manufacturing the same, which can be made into a cylindrical knitted fabric at low cost while suppressing deterioration in wearing comfort and quality. The object of the present invention is to provide a technology capable of imparting an anti-slip function to an anti-slip part of a knitted fabric.

A first characteristic configuration of the present invention is a method for manufacturing a tubular knitted fabric having an anti-slip portion formed by exposing a high-friction material, the method comprising:
a knitting step of knitting the non-slip portion using a covering yarn obtained by covering the core yarn made of the high friction material with a wound yarn that can be dissolved and removed;
The method further includes a dissolving and removing step of dissolving and removing the winding yarn from the anti-slip portion knitted in the knitting step to expose the core yarn.
Further, the characteristic structure of the tubular knitted fabric according to the present invention is that it is a tubular knitted fabric having an anti-slip portion formed by exposing a high-friction material, and is manufactured by the method for manufacturing a tubular knitted fabric according to the present invention. The non-slip portion is configured such that the core yarn made of the high friction material is woven in a state where it is exposed to the outside.

According to this configuration, the dissolving and removing step is performed on the non-slip portion knitted in the knitting step, and the winding yarn is dissolved and removed from the covering yarn used to knit the non-slip portion. The anti-slip portion is configured as a knitted fabric in which core threads made of a high-friction material are woven to the outside. Therefore, the tubular knitted fabric can be provided with an anti-slip portion in which the knitted fabric itself has an anti-slip function due to the core yarn made of a high-friction material exposed to the outside.
If the anti-slip portion is configured in this manner, it is not necessary to coat the knitted fabric with a high-friction material in order to provide the anti-slip function, so it is possible to reduce costs and improve wearing comfort. Furthermore, in the knitting process, it is difficult to knit a core yarn made of a high-friction material as it is because yarn feeding defects are likely to occur, but with this configuration, it is difficult to knit a core yarn made of a high-friction material as is. Instead, the yarn is knitted as a covered yarn that is covered with a winding yarn that can be dissolved and removed, so that it is possible to prevent quality deterioration due to breakage and expansion/contraction of the core yarn while suppressing defects in yarn feeding.
Therefore, according to the present invention, it is possible to provide a tubular knitted fabric and a method for manufacturing the same, which can provide an anti-slip function to the anti-slip portion of the tubular knitted fabric at low cost while suppressing deterioration in wearing comfort and quality. can.

A second feature of the present invention is that the core yarn is an elastomer yarn.

According to this configuration, a thread made of an elastomer such as silicone rubber, natural rubber, or urethane rubber, which is easily available, can be used as the core thread of the covering thread. The anti-slip part after the dissolution and removal process is a knitted fabric in which the elastomer threads are exposed to the outside, so the knitted fabric itself has an anti-slip function due to the elastomer core yarn. A stop portion can be provided on the tubular knitted fabric.

A third feature of the present invention is that, in the knitting step, the anti-slip portion is knitted using one of the front yarn and the back yarn as a covering yarn and the other as a non-dissolvable yarn.

According to this configuration, in the anti-slip part after the dissolution and removal process, the core yarn made of high friction material is exposed on one side of the front grain side and the back grain side, and the non-dissolving material is exposed on the other side. The front thread is now exposed. Therefore, the tubular knitted fabric can be provided with an anti-slip portion having an anti-slip function only on one side of the front stitch side and the back stitch side.

A fourth feature of the present invention is that, in the knitting step, the covering yarn is used as a pattern yarn and fed to a non-dissolvable ground yarn to knit the anti-slip portion.

According to this configuration, in the non-slip part after the dissolution and removal step, the non-dissolvable ground yarn is exposed in the non-pattern part where the pattern yarn is not fed, and the pattern part where the pattern yarn is fed has high friction. The core yarn made of the material will be exposed. Therefore, by adjusting the occupied area, arrangement, etc. of the handle portion having an anti-slip function in the anti-slip part, the degree and state of the anti-slip function in the anti-slip part can be set to an appropriate value.

A fifth feature of the present invention is that in the knitting step, the anti-slip portion is knitted only with the covering yarn.

According to this configuration, for example, in a form in which both the front thread and the back thread are covering threads, or in a form in which the covering thread is used as the face thread and the back thread is omitted, the non-slip part is formed using only the covering thread in the knitting process. Because of this, the core yarn made of the high-friction material is exposed on both the front side and the back side of the anti-slip part after the melting and removal process. Therefore, the tubular knitted fabric can be provided with an anti-slip portion having an anti-slip function on both the front stitch side and the back stitch side.

A sixth feature of the present invention is that in the knitting step, the covering yarn is skipped in the course direction or the wale direction.

According to this configuration, in the anti-slip portion after the dissolution and removal step, the core yarn made of the high-friction material is in a state where it is skipped and woven in the course direction or the wale direction. Therefore, by adjusting the number of stitches skipped by the core yarn having an anti-slip function in the anti-slip part, the degree and condition of the anti-slip function in the non-slip part can be set appropriately. Air permeability can be improved by the part where the particles are blown off.

A seventh characteristic configuration of the present invention is that the tubular knitted fabric is a sock,
The anti-slip portion is provided on at least a portion selected from the sole, heel, collar, and calf.

According to this configuration, when manufacturing socks as a tubular knitted fabric, it is possible to suppress deterioration in comfort and quality and at low cost, and to produce socks at the sole part (for example, the base of the toe) or the heel part (for example, the front of the heel) of the sock. An anti-slip part having an anti-slip function can be provided at the shoe opening (for example, the entire circumference or the rear part) or the calf part (for example, the upper and lower parts sandwiching the thickest part).

An eighth characteristic configuration of the present invention is that the tubular knitted fabric is a glove,
The anti-slip portion is provided on at least a portion selected from the finger portion, the shoe opening, and the palm portion.

According to this configuration, when manufacturing gloves as a tubular knitted fabric, it is possible to suppress the deterioration of wearing comfort and quality at low cost, and to produce gloves such as finger parts (e.g., fingertips), opening (e.g., entire circumference), palm of the glove, etc. A non-slip part having a non-slip function can be provided in the part.

That is, in the knitting process, as shown in FIG. 3, the anti-slip portion 2 is knitted using a covering yarn 5 formed by covering a core yarn 5a made of a high friction material with a winding yarn 5b that can be dissolved and removed. .
In the dissolving and removing step after the knitting step, the winding yarn 5b constituting the covering yarn 5 is dissolved and removed from the anti-slip portion 2 knitted using the covering yarn 5 as described above. The core yarn 5a is exposed.
The high-friction material constituting the core yarn 5a may be any material that exhibits high frictional resistance against the contact surface, and for example, elastomers such as silicone rubber, natural rubber, and urethane rubber can be suitably used. .

The winding yarn 5b constituting the covering yarn 5 may be a yarn made of a water-soluble synthetic resin such as water-soluble vinylon (for example, "Solblon yarn" manufactured by Nichibi Co., Ltd.) or a heat-soluble synthetic resin such as a low-melting point nylon. A thread made of resin (for example, "Elder Yarn" manufactured by Toray Industries, Inc.) can be used.
When a thread made of water-soluble synthetic resin is used as the winding thread 5b constituting the covering thread 5, for example, in the dissolving and removing step, at least the non-slip portion 2 of the foot cover 10 knitted in the knitting step is removed. However, the winding thread 5b made of water-soluble synthetic resin can be dissolved and removed from the anti-slip portion 2 by washing with hot water or the like having a temperature higher than the melting temperature of the winding thread 5b made of the water-soluble resin.
Furthermore, in the case of using a thread made of a heat-melting synthetic resin as the winding thread 5b constituting the covering thread 5, for example, in the dissolving and removing step, at least the non-slip portion of the foot cover 10 knitted in the knitting step is removed. 2, the winding thread 5b made of heat-fusible synthetic resin is dissolved and removed from the anti-slip part 2 by performing heat treatment such as blowing hot water and hot air at a temperature higher than the melting point of the winding thread 5b made of the heat-melting resin. can do.

The anti-slip portion 2 is constructed as a knitted fabric in which a core yarn 5a made of a high-friction material is woven with the core yarn 5a exposed to the outside. That is, the tubular knitted fabric 1 is provided with the anti-slip portion 2 in which the knitted fabric itself has an anti-slip function due to the core yarn 5a made of a high-friction material exposed to the outside.
In addition, in order to improve the air permeability of the non-slip part 2, the covering yarn 5 is skipped in the course direction or the wale direction during the knitting process, so that the core yarn 5a having an anti-slip function is skipped in the non-slip part 2. You can also adjust the number of stitches, etc.

Referring to FIG. 2, the sole anti-slip part 12a located on the sole part 12 and the heel anti-slip part 14a located on the heel part 14 have backlash that comes into contact with the wearer's skin 18 (sole and heel). The core yarn 5a made of a high friction material is exposed on both the side and the outer side that contacts the shoe 17, and exerts high frictional resistance against the wearer's skin 18 and the shoes 17 that come in contact with the sole of the foot. 12 and the heel portion 14 from shifting.

Instead of using the ring yarn 5, the knitted fabric 7 may be knitted by feeding only the covering yarn 5 as the front yarn 7a and stopping the feeding of the back yarn 7b.

Further, in the finger anti-slip portion 48a, the anti-slip function may be provided only on the front side without providing the anti-slip function on the back side. In this case, in the knitting process, the covering yarn 5 (see FIG. 3) is used as the front yarn 7a, and a non-dissolvable yarn is used as the back yarn 7b. The winding thread 5b is removed from the covering thread 5 which has been knitted as a woven covering thread. Then, in the finger anti-slip portion 48a configured in this way, the core yarn 5a made of a high friction material is exposed only on the front side, and the core yarn 5a is not exposed on the back side and the above-mentioned high The non-dissolvable threads, which have a lower frictional resistance than the frictional material, are exposed. As a result, the finger anti-slip portion 48a configured in this manner exhibits an anti-slip function on the front side that contacts the object to be held.

Regarding the plurality of palm part anti-slip parts 49a located in the palm part 49, core threads 5a made of a high friction material are exposed only in the handle part such as a polka dot pattern, and the wearer's palm or the object held in the handle part is exposed. The palm part 49 is configured to exert high frictional resistance against contact targets such as the palm part 49 and prevent the palm part 49 from slipping.

Specifically, the palm anti-slip portion 49a is knitted by feeding the covering yarn 5 (see FIG. 3) to the non-dissolving ground yarns 7a and 7b as the pattern yarn 7c in the knitting process, and then In the dissolving and removing step, the winding thread 5b is removed from the covering thread 5 knitted as the pattern thread 7c. Then, in the palm anti-slip portion 49a configured in this way, the core yarn 5a made of a high friction material is exposed at the handle portion where the pattern yarn 7c is fed, and the non-pattern portion where the pattern yarn 7c is not fed. In some portions, non-dissolvable ground yarns 7a and 7b having a lower frictional resistance than the high friction material are exposed. As a result, the palm anti-slip portion 49a configured in this manner exhibits an anti-slip function at the handle portion.
Further, when knitting the palm anti-slip portion 49a in which the covering yarn 5 is fed as the pattern yarn 7c, the feeding of one or both of the front yarn 7a and the back yarn 7b may be stopped.

[Another embodiment]
Other embodiments of the present invention will be described. Note that the configurations of each embodiment described below are not limited to being applied individually, but can also be applied in combination with the configurations of other embodiments.

(1) In the above embodiment, in order to set the surfaces and portions that have an anti-slip function in each anti-slip part 2, covering yarns 5 are formed in the knitted fabric 7 from the front yarn 7a, the back yarn 7b, and the pattern yarn 7c. Although an example has been described in which the thread using the covering thread 5 is appropriately set, the thread using the covering thread 5 in each of these anti-slip parts 2 can be changed as appropriate.

(2) In the above embodiment, socks 10, 20, 30 and gloves 40 were described as embodiments of the tubular knitted fabric and the manufacturing method thereof according to the present invention, but the present invention can also be applied to other tubular knitted fabrics. can be applied.

(3) In the above embodiment, one of the front yarn 7a and the back yarn 7b is made of non-dissolvable yarn in order to provide an anti-slip function to one of the front stitch side and the back stitch side of the knitted fabric 7. The fabric 7 was knitted using the covering yarn 5 on the other side, but when the covering yarn 5 is used on one side of the front yarn 7a and the back yarn 7b in this way, the front yarn 7a and the back yarn 7b are separated during knitting. By appropriately exchanging these, the knitted fabric 7 can be knitted in such a manner that the surfaces having an anti-slip function are appropriately exchanged between the front side and the back side.

(4) In the above embodiment, as shown in FIG. 3, the anti-slip portion is knitted using the covering yarn 5, which is formed by covering the core yarn 5a made of a high friction material with the winding yarn 5b which can be dissolved and removed. However, as shown in FIG. 9(a), a non-dissolvable reinforcing winding thread 5c having a diameter smaller than that of the winding thread 5b (for example, 1/10 the diameter of the winding thread 5b) is wound around the core thread 5a in advance. The anti-slip portion may be knitted using a covering thread 51 obtained by covering a core thread 5a around which the reinforcing thread 5c is wound with a winding thread 5b which can be dissolved and removed. This makes it possible to make the covering yarn 51 high-strength and low-stretch, thereby facilitating the knitting process using the covering yarn 51. In the dissolving and removing step after knitting, as shown in FIG. 9(b), only the winding thread 5b is melted and removed and the reinforcing winding thread 5c remains wrapped around the core thread 5a. This can contribute to reinforcing the knitted anti-slip section. In addition, since the reinforcing thread 5c is sufficiently thinner than the winding thread 5b, a portion of the core thread 5a made of a high friction material is exposed between the reinforcing threads 5c. The non-slip portion can have an anti-slip function due to the portion of the core thread 5a. In addition, in FIG. 9(a), the reinforcing thread 5c is wound around the core thread 5a, and then the winding thread 5b is wound around the core thread 5a. It is also possible to feed the threads and wind them at the same time, or to wind the reinforcing thread 5c after winding the thread 5a. Further, the winding direction and pitch of the reinforcing winding thread 5c around the core thread 5a may be different from those of the winding thread 5b.
