Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of weaving a retroreflective functional sock and a sock by the weaving method,

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a method of weaving a retroreflective functional sock and a sock by the weaving method, and more particularly, A method of weaving a retroreflective functional sock that secures the safety of the wearer and exerts a visual effect, and the provision of a sock by the weaving method.

In general, socks are clothing worn on the feet or legs for winter or aesthetic purposes, and can be classified into various types such as socks, stockings, tights, and sports socks depending on the purpose and form of use.

Most socks are woven with elastic (elastic) material to give a comfortable fit. The yarn used to weave socks is generally used as outer yarn, spun and nylon yarns used for inner yarn, polyester yarn for pattern, and polyurethane.

The weaving process of the sock will be roughly described as follows. First, a designing step of designing and designing a concept according to the kind of sock, that is, a purpose of use, a weaving step of inputting design data into a knitting machine, knitting yarn, A sewing step of sewing the front part of the sock, a step of putting the sock on the foot-shaped model, a step of forming the shape of the sock using the steam machine, and a finishing step.

On the other hand, the development of sock weaving technology using materials having functionality such as breathable waterproof, sweat-absorbent quick-drying, flameproofing, antibacterial, high stretchability, gloss and far-infrared rays has been actively carried out to give various functions to socks, and high quality multi- .

Especially, in recent years, outdoor clothing, bags, shoes and other products using retroreflective functionality considering the safety of the wearer can be easily accessed in accordance with the increasing trend of various outdoor activities.

Reflective reflectance refers to the reflection of incoming light back to the direction of the light source. The most common example is the reflective film attached to the road sign, which illuminates the light of a car headlight to reflect to the driver, thereby increasing the visibility of the road sign For example.

As such, the material exhibiting the retroreflective function is generally formed by coating a fine glass bead or a metal powder on a fabric, a film or a sheet uniformly, or by forming a micro prism on a polymer film. Respectively.

A typical example of the product having the above-described retroreflective functionality is described in more detail through a recursive reflective shoe of the known registered utility model No. 20-0281297 as follows.

A shoe comprising a shoe upper, a bottom window, and a string fastener, wherein the shoe comprises a shoe upper, a cover, or a reflective sheet having a retroreflective structure that emits light by receiving outside light at night at the outer surface of the shoe window Or sewing it so as to have a retroreflective structure on the outer surface of the shoe.

The reflective sheet may be formed by applying an adhesive to a top surface of a nonwoven fabric to form an adhesive layer, applying a glass bead to the upper surface of the fabric to form a glass bead layer, And laminating by fusion.

The reflective sheet is formed by inserting a soft resin film between upper and lower molds of a press thermo-compression processing apparatus, forming a plurality of uneven surfaces on the bottom surface of the soft resin film by pressure and heat, Or to the inside of the cover or bottom window.

The reflective sheet may be formed by passing a flexible resin film between upper and lower compression rollers of a film processing apparatus to form a plurality of uneven surfaces on the bottom surface of the soft resin film by pressure and heat, Or to be directed toward the inside of the bottom window.

Meanwhile, a technology applied to the sock has been developed and provided by expanding the application range of the retroreflective structure applied to the registered utility model. The construction of the reflective sock known in the registration utility model No. 20-0420211 will be described below.

It can be cut and sewed on regular socks and has excellent light reflection performance. It is designed with various shapes of reflective fabric to maintain excellent reflection performance even after washing, and the tailored reflective fabric is sewn to the top of socks. To form a reflecting surface serving as a reflector for reflecting the light to obtain a glittering reflector effect.

Registered Utility Model No. 20 - 0281297 - 0000 Registered Utility Model No. 20 - 0420211 - 0000 Registered Utility Model No. 20 - 0265823 - 0000 Registration Utility Model No. 20 - 0260983 - 0000

The reflective sock of the registered utility model No. 20-0420211 to which the above-described conventional technique is applied is a retroreflective structure attached to an outdoor garment which is commonly used in contact with us, that is, a recursion included in the reclining reflective shoe of the registered utility model No. 20-0281297 Like the reflective structure, the reflective film, sheet, and fabric are adhered to the product using adhesive, heat seal, or sewing.

However, since the retro-reflective structure is attached to the outer side of the finished sock, the reflective sock to which the conventional technique as described above is attached requires a separate process of manufacturing and cutting the retroreflective structure and attaching the retro-reflective structure to the product .

Thus, there is a problem that the sock weaving process takes a long time and the manufacturing cost is increased.

In addition, by attaching the above-described retroreflective structure to the surface of the finished sock, it is possible to feel a sense of differentiation from the fabric when the sock is worn, to reduce the feeling of wearing such as stimulating the foot skin, And the like.

In addition, since the socks are easily exposed to external friction due to the fact that they are worn on the feet, and the frequent washing process is accompanied, problems such as detachment of the retroreflective structure and detachment from the sock are caused.

In order to overcome the problems of the prior art as described above, the present invention is different from the method of attaching a retroreflective structure such as a film or a sheet to a sock, As to the weaving technique, generally, recursion yarns have very weak strength and elasticity compared with ordinary yarns. Therefore, when weaving with conventional socks weaving method using recursion fact, Or can not maintain a constant tension, so that the sock can not be sewn normally.

Accordingly, the present invention has been made to solve the above-mentioned problems,

A rewinding step S100 of winding the recursive yarn 101 at a speed of 150 占 rpm at S110 and winding the yarn at a specific cone S130; (100) is formed through a knitting step (S200) in which a yarn (102) is fed to a knitting machine (103) and knitted at a speed of 100 10 rpm;

In the rewinding step S100, waxing process S120 is performed to reinforce the elasticity and flexibility of the recursive yarn 101 and wound on a special cone (S130) Lt; / RTI >

In the knitting step S200, the recursive yarn 101 fed to the knitting machine 103 is fed and knitted while maintaining a predetermined tension by the tension adjusting means 107, so that the sock with the recursive reflection pattern is woven It is possible to accomplish a goal that can be done.

The present invention provides a functional sock capable of securing the safety of a sock wearer and exhibiting a visual effect by constructing a sock with a recursive reflection pattern for reflecting light incident from a light source by knitting ordinary fiber yarn It is effective.

Therefore, compared to the conventional technique in which a film or a sheet is attached, the present invention is effective in reducing the process time because the retroreflective pattern is woven in the sock itself during the weaving process using the knitting machine, There is an advantage to be able to.

Particularly, it is possible to overcome the disadvantages of the recursive yarn which can not be used as a normal yarn for sock knitting because the strength and elasticity are so weak that the recursion yarn is not cut or sagged during the marine or knitting process, There is an advantage in that the sock can be knitted effectively by knitting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for weaving a retroreflective functional sock according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a view showing the structure of a sock made according to an embodiment of a sock according to the weaving method of the present invention and the sock by the weaving method, Fig. 2 is a view showing a method of weaving the retroreflective functional sock of the present invention and the weaving method Fig. 3 is a configuration diagram illustrating an operation state of the tension adjusting means according to the embodiment of the sock according to the weaving method of the retroreflective functional sock of the present invention and the weaving method of the present invention, Fig. 4 is a view showing an example of a retroreflective and posterior state of a sock made according to an embodiment of a sock according to an embodiment of the sock by the method of weaving the retroreflective functional sock of the present invention and the sock by the weaving method, As well as an example image of a half-fact according to an embodiment of the sock by the weaving method.

The method of weaving a retroreflective functional sock and the sock by the weaving method to which the technique of the present invention is applied is characterized in that the sock is fed to the knitting machine 103 with the recursive yarn 101 and the plain yarn 102 together So that the sock 100 having the retroreflective pattern 110 is formed on the sock itself.

To this end, in the present invention, a rewinding step (S100) in which the recursive yarn 101 is marred at a speed of 150 ± 10 rpm (S110) and wound around a dedicated cone (S130) ) And a normal fiber yarn 102 are fed to a knitting machine 103 and knitted at a speed of 100 10 rpm to form a sock 100 having a reflex reflection pattern 110 formed thereon.

A conventional sock weaving process is performed by winding a yarn made of ordinary yarn such as cotton yarn, nylon yarn, and polyester yarn on a knitting machine, as described in the background art, and then using a motor to yarn the yarn from the bobbin Knitted by knitting needle of knitting machine.

The yarn winding and yarn winding speed of the yarn wound on the bobbin is set in consideration of yarn strength and knitting efficiency, and is generally 270-330 rpm in a normal sock weaving method.

In contrast, in the method of weaving the retroreflective functional sock of the present invention, since the recursive yarn 101 is fed to the knitting machine 103 together with the normal fiber yarn 102 to perform the knitting step S200, 102, the recursive yarn 101 having a very weak strength and elasticity can not be easily cut and normal sock weaving can be performed when the yarn 101 is subjected to marine and yarn feeding at the same speed as a normal sock weaving method.

The recursive yarn 101 used in the preferred embodiment of the present invention is a 3M Scotchlite ^TM Reflective Yarn from 3M, and typically the recursive yarn is a metal powder such as aluminum or silver, The adhesive sheet is manufactured in such a manner that the sheet is finely cut in the form of a thread, which is well known in the related art, so a detailed description thereof will be omitted.

Therefore, the recursive yarn 101 as described above has almost no strength and elasticity as compared with the ordinary fiber yarn 102 formed by twisting the fibers, so that even if a weak tensile force is applied, will be.

Therefore, in order to overcome the above-mentioned problem, according to the present invention, the recursive yarn 101 wound around a conventional cylindrical bobbin is sailed (S110), and wound into a cone-shaped special cone And a rewinding step S100 for performing a rewinding operation.

In order to prevent the recursive yarn 101 from being cut in the rewinding step S100, the marine speed is sailed at a low speed of 150 10 rpm (S110) and wound around a special cone (S130) Also, the problem of adsorption phenomena between the yarn strands due to the increase of the tensile strength is also excluded.

As described above, even when the recursion part facts 101 are wound on the dedicated cone (S130), there is no change in the material properties such as weak strength and weak elasticity of the recursive part 101 itself, It is not possible to completely exclude the possibility of cutting the work 101.

Therefore, in the rewinding step S100, the recursive yarn 101 having been subjected to the marine treatment (S110) to enhance the elasticity and flexibility of the recursion yarn 101 is subjected to a waxing process S120, S130).

In the waxing process (S120), the wax is applied to the surface of the recursive pottery 101, or impregnated to coat the recursive pot 101 with the wax.

The wax agent may be a commercially available softener or paraffin lead, and the wax agent may act as a bridge between the fibers of the recursive yarn 101 to enhance tensile strength and elasticity.

The waxing process (S120) is a method in which the wax is sprayed on a path through which the recursion yarn 101 is marred (S110) and wound on a special cone (S130) or impregnated into a general container to coat the surface .

After the rewinding step S100, which is followed by the marine slip S110, the waxing process S120 and the dedicated cone winding S130, the recursive yarn 101 and the normal yarn 102 Is knitted at a knitting speed of 100 ± 10 rpm compared to a knitting speed of a normal sock at a knitting step S200 to obtain a recursive half fact ) Is completely excluded.

In addition, in the knitting step S200, the recursive yarn 101 fed to the knitting machine 103 is fed and knitted while maintaining a predetermined tension by the tension adjusting means 107. [

The yarn wound around the several bobbins provided on one side of the knitting machine is divided into a plurality of yarns which are annularly provided in the lower part through the marine rollers and guides on the upper side of the knitting machine, Knitting is performed through the path of yarn fed by the knitting needles.

In this process, the ordinary fiber yarn 102 using nylon or the like is fed to the knitting needle while maintaining the tension constantly due to the material property. However, the recursion yarn 101 does not perform the waxing process (S120) It is difficult to maintain a certain level of tension throughout the knitting process.

Particularly, the recursive yarn 101 is fed only when knitting an area forming the recursive reflection pattern 110, and is temporarily stopped when an area without the recursive reflection pattern 110 is knitted. Repeated interruptions cause the tensile strength of the yarn to drop sharply, resulting in striking or sagging, which can lead to serious problems such as thread twist.

Therefore, in the present invention, even if the squeezing or slacking occurs as described above by providing the tension adjusting means 107 on the path where the recursive yarn 101 is fed to the knitting needle 105, by the tension adjusting means 107 So that a constant tension can be maintained.

In the preferred embodiment of the present invention, as shown in the structure diagram exemplifying the operating state of the tension adjusting means 107 in Fig. 3, the knitting needles 105 on the underside deep portion of the fishing guide 104 on the upper portion of the knitting machine 103, A tension adjusting means guide 106 is provided in an outer oblique direction opposite to the recursion main body 101 extending in a diagonal direction so as to be movable up and down along a tension adjusting means guide 106 107 to the inner diameter portion of the tension adjusting means 107, and the yarn is fed to the knitting needle 105 through the recursive yarn 101. [

Therefore, even if the tension of the recursive yarn 101 is relaxed in the state in which the yarn feeding of the recursion yarn 101 is stopped, the tension adjusting means 107 adjusts the tension adjusting means guide 106 And moves downward to ride on the yarn to maintain the tension.

In addition, when the reflexive yarn 101 is re-tensioned and tensioned, the tension adjusting means 107 is moved upward along the tension adjusting means guide 106 by the pulling force of the recursive yarn 101.

The sock is formed by knitting the recursive yarn 101 and the normal fiber yarn 102 by the weaving method of the reflex reflection functional sock according to the present invention as described above, (100) is provided to exhibit the function of reflecting the incident light.

Meanwhile, the retroreflective pattern 110 is woven in a form selected from a character, a point, a graphic, a logo, and a character. The shape and position of the retroreflective pattern 110 may be selectively formed considering the design of the sock.

Therefore, the method of weaving the retroreflective functional sock and the sock by the weaving method, to which the technique of the present invention is applied, has the following advantages.

First, the present invention is knitted together with a normal fiber yarn 102 by using a recursive yarn 101 which is very weak in strength and elasticity and is not usable as a conventional yarn for sock weaving, so that the retroreflective pattern 110 is integrally formed The formed sock 100 is woven to secure the safety of the sock wearer and to provide the functional sock with a visual effect.

Particularly, in order to overcome the disadvantage of the recursive yarn 101 that is easily cut in the knitting process, in the present invention, the recursion yarn 101 is waxed after the yarn S110 and wound around the special cone S130 (S100), and a knitting step (S200) in which yarn is fed and knitted while maintaining a predetermined tension by using a tension adjusting means (107).

Therefore, even when the recursive yarn 101 is knitted together with the normal fiber yarn 102, there is an advantage that normal knitting can be performed by eliminating the occurrence of a cut or sagging phenomenon.

Ultimately, the finished sock 100 according to the method of weaving the retroreflective functional sock according to the preferred embodiment of the present invention is superior to the conventional sock made by sticking and fusing the reflective film or sheet, 110) It is expected to have various advantages such as not to feel a foreign body sensation or stimulation differentiated from the sock cloth on the contact portion, and to improve the wearability.
