{Cord yarn for zipper and reflective zipper}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a code yarn for zipper and a reflective zipper, and more particularly, to a zipper cord for zipper which can increase the visibility of the zipper by the retroreflective property of the semi- Yarn and reflective zipper.

Retroreflective refers to the reflection of light from a light source onto the surface of an object and back to the light source. Reflecting light from any angle reflects light back toward the light source. Such retroreflective materials are widely used in road signs, safety vests, cloths, and shoes. That is, a retroreflective material is cut and attached in a specific shape in order to enhance the visibility of the safety garment or work clothes. When the retroreflective material is irradiated with light, it can be easily identified at a distance of about 300 m at night. Therefore, retroreflective materials are attached to various daily necessities such as clothes, hats, shoes, bags and protect from danger.

On the other hand, a yarn with a retroreflective property, that is, a half-fact is being developed. However, it is necessary to develop a zipper thread including semi-fact that it can be easily inserted into a zipper and applied to a zipper such as a clothes to apply the effect of reflex reflection .

Korean Utility Model Registration No. 20-0247552 (Name of invention: colored anti-fact) Korean Patent Laid-Open Publication No. 10-2012-0014377 (entitled " Korean Patent Registration No. 10-1118832 (entitled "High-strength functional yarn and method for producing the same") Korea public utility model public office room 2000-0015135 (title of invention: half truth)

Accordingly, it is an object of the present invention to provide a zipper cord yarn which is formed to solve the above-mentioned problems, and which includes a half yarn for enhancing the visibility of the conventional zipper.

However, the objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

The above-described object of the present invention can be achieved by providing a cord yarn for a zipper which comprises a core yarn and a covering yarn covering the core yarn.

In addition, the core yarn has a relatively low elongation as compared with the covering yarn, and the covering yarns cover the core yarns by S-shaped yarns at regular intervals.

The core yarn is made of polyester or nylon, and the zipper cord yarn is coated with a polyurethane resin so that the interval between the cord yarn and the covering yarn is kept constant.

Further, since the interval is formed to be narrower or equal to the width of the covering yarn, the surface of the zipper cord yarn becomes uniform or smooth.

The interval is in the range of 90 to 95% with respect to the width of the covering yarn.

The width of the covering yarn is 0.38 mm to 3 mm.

In addition, the interval is 1 mm.

The object of the present invention is also achieved by a zipper tape, a tooth fixed to the zipper tape, a stitching yarn for fastening the teeth to be fastened to the zipper tape, and the zipper cord yarn according to any one of claims 1 to 7 The present invention can be achieved by providing a reflective zipper which is characterized in that

Also, the zipper code yarns are inserted into the teeth and stitched by the stitching yarn to be fixed.

In addition, the stitching yarn is a covering yarn for covering the core yarn made of semi-fabric yarns and the core yarn.

Further, the core yarn and the covering yarn are twisted by braiding.

In addition, the abrasion strength and the tensile strength of the core yarn are relatively weak as compared with the covering yarn, and the core yarn and the covering yarn are twisted by the braiding method, thereby further increasing the abrasion strength and tensile strength.

Also, the covering yarn is nylon yarn or polyester yarn.

According to the present invention as described above, the visibility is significantly improved as compared with the conventional zipper.

Further, when the stitching yarn of the present invention is used with a high-strength reflective functional yarn, there is an effect that a larger reflection area of the zipper can be formed.

In addition, the description of the prior art and those obvious to those skilled in the art may be omitted, and the description of the omitted components and the function may be sufficiently referred to within the scope of the technical idea of the present invention.

<Code for zipper>

1 and 2, the cord yarn 10 for a zipper according to an embodiment of the present invention comprises a core yarn 100 provided on the inner side and a covering yarn 200 covering the core yarn from the outside, . The core yarn 100 is preferably formed of polyester or nylon having a low elongation. Therefore, it is preferable to use a material having a smaller elongation than that of the covering yarn 200. The core yarn 100 is formed by uniformly twisting polyester or nylon during twisting.

The twisted reflective slitted film 200 is made up of semi-facts as shown in FIG. As shown in FIG. 1, the glass bead 210, the reflection layer 220, the polyurethane resin layer 230, and the frame layer 240 are roughly formed. At this time, light coming from the outside is refracted by the glass bead 210 and reflected by the reflection layer 220. The frame layer 240 is made of polyester fiber or PET or PE as a base layer or a base layer for maintaining a semi-true shape, the polyurethane resin layer is an adhesive layer, and the reflective layer 220 is an aluminum deposition layer. It is to be understood, however, that the present invention is not limited to the above embodiments, but may be modified and changed without departing from the scope and spirit of the invention.

As shown in FIG. 2, the cord yarn 10 for a zipper according to the embodiment of the present invention includes a core thread 100 and an inner core yarn 100, And a covering yarn 200 surrounding the cover yarn. At this time, when the core yarn 100 is wrapped with the "S &quot;, the width W ₁ between the core yarn 100 and the covering yarn 200 is important. This is because if the surface of the zipper code yarn 10 is made to be smooth (i.e., when the surface of the zipper cord yarn is rubbed, it feels as if it is formed as a single yarn so as not to distinguish the core yarn and the covering yarn) This is because it is easily inserted into the teeth 220 and the stitching yarn 230 can be easily stitched and fastened to the zipper tape 210.

The width or spacing width (W ₁ ) of the gap is preferably narrower or at least equal to the width (W ₂ ) of the covering yarn. By keeping the spacing width narrower or at least equal to the width of the covering yarn, the surface of the zipper cord yarn 10 can be made uniform or smooth. At this time, it is preferable to coat the surface of the cord yarn 10 for zipper with a polyurethane resin so as to keep the spacing width uniform. When coated with polyurethane resin, it is possible not only to keep the spacing width uniform, but also to make the core yarn and the covering yarn cohesive. At this time, maintaining a sense of unity means that the covering yarn keeps the spacing width without loosening from the core yarn even if the covering yarn is twisted in a direction opposite to the direction in which the core yarn is twisted. Therefore, the zipper code yarn 10 is formed in such a manner that the covering yarn 200 is stretched in the " S "shape to the core yarn 100, but the separation width can be maintained unchanged by the surface coating of the polyurethane resin.

The spacing width W ₁ is preferably about 90 to 95% relative to the width W ₂ of the covering yarn. More preferably, the separation width W ₁ has a width of approximately 1 mm. It is preferable that the spacing width W ₁ is uniformly applied to the entire length of the zipper cord yarn 10. On the other hand, it is preferable that the width (W ₂ ) of the covering yarn is formed within approximately 0.38 mm to 3 mm. If the width (W ₂ ) of the covering yarn is smaller than this range, the reflection effect will be lowered and the strength will be weaker. If the width is smaller than this range, the workability will be lowered when used in a zipper.

<Reflective Zipper>

The reflective zipper 20 can be used in clothes as an example. In other words, there is a zipper on the clothes, and the zipper is made so that pieces of metal or plastic are juxtaposed with cloth tape so that the teeth can be engaged with each other, and the two lines can be pulled and pulled by the rings. By applying the cord yarn 10 for zipper according to an embodiment of the present invention to the zipper, light can be reflected from the zipper, and high visibility can be added at night or in a dark place. Therefore, the reflective zipper 20 according to an embodiment of the present invention can be applied to all of those in which a zipper is used, including clothes, running shoes, and the like.

The reflective zipper 20 according to an embodiment of the present invention roughly comprises a tape 21, a tooth 22, a stitching yarn 23, and a cord yarn 10 for a zipper, as shown in Fig. The tape 21 is made of polyester. The teeth 22 are composed of the first and second teeth 22a and 22b so as to engage with each other. The teeth 22 are formed by molding a poly-mono yarn. The stitching yarn 23 is used to stitch the teeth 22 and the cord yarn 10 for zipper on the tape 21. That is, the teeth 22 and the code yarn for the zipper are sewn to the tape 21 by the stitching yarn 23. The stitching yarn 23 is stuck in the groove region 22c between the teeth and the teeth as shown in Fig.

4, the zipper code yarn 10 is inserted into the first and second teeth 22a and 22b and is stuck to the tape 21. As shown in FIG. The first code yarn 11 is inserted into the first tooth 22a and is stuck on the tape 21 and the second code yarn 12 is inserted into the second tooth 22b to be stuck on the tape 21, do. Therefore, the light is reflected by the covering yarn (or semi-yarn) included in the zipper code yarn 10, so that light is reflected in a dark place, so that the visibility of the zipper can be enhanced.

5, the first stitching yarn 23a is used to stitch the first teeth 22a and the first code yarn 11 to the tape 21 and the second stitching yarn 23b is used to stitch the second And is used when the tooth 22b and the second code yarn 12 are stuck to the tape 21. At this time, the stitching yarn 23 may be a yarn commonly used for a zipper as a first embodiment and a high-strength reflective functional yarn as a second embodiment. The high-strength reflection functional room of the second embodiment will be described later.

The step of fastening the zipper cord yarn to the zipper roughly first forms the teeth 22 while forming the poly monosaccharide, and at the same time, the zipper cord yarn 10 enters the teeth 22, And the zipper code yarn 10 are stitched on the tape 21 by using the stitching yarn 23 and sewed together. At this time, since the zipper code yarn 10 is formed smoothly and integrally, it is easily inserted into the teeth 22 easily. Thus, it is important that the tooth 22 is easily inserted into the tooth 22 easily.

&Lt; Second embodiment of stitching company: High-strength reflective functional room &

The stitching yarn 30 as shown in Fig. 6 is made of a high-strength reflective functional yarn. Since the stitching yarn 30 is made of a high-strength reflective functional yarn, it is possible to form an area more reflected by the zipper 10 in addition to the zipper cord 10. The first sewing thread 31 made of a high strength reflective functional yarn is used to stitch the first teeth 22a and the first cord yarn 11 onto the tape 21 and the second sewing thread 32 is used to fasten the second teeth 22b, And the second code yarn 12 to the tape 21. [0043]

The high-strength functional yarn of the present invention is a reflecting yarn. In general, since the strength is weak, the high-strength functional yarn according to an embodiment of the present invention has a strong strength and retroreflective property by twisting the covering yarn by the braiding method to the core yarn half yarn. The core sign half truth is used in various places as a thread to be a reflex reflection. Such counterfeiting is weak in general characteristics. Therefore, in order to increase the strength, the cover yarn must be spun on the half yarn. In case of performing the yarn in the general S (right-handed) or Z (left-handed) manner, not only the effect of the reflex reflection is lowered, Is loosened or broken due to the difference of the different tensile strength. In the present invention, the core yarn half yarn and the covering yarn are twisted by the braiding method to make up for the low yarn count, and furthermore, the nature of the reflex yarn possessed by the half yarn can be doubled.

A covering yarn according to an embodiment of the present invention is spun into a core yarn half yarn. A transparent (colorless) or opaque (colored) covering yarn is twisted to the core yarn half yarn by a braiding method. That is, in order to maximize the effect of the retroreflection, it is preferable that the covering yarn is transparent to the semi-fabric, and when various color colors are desired, it is preferable to provide colored covering yarns to the semi-fabric. Further, Covering yarns may be mixed and twisted to the core yarn by a braiding method. In the case of mixing colored and colorless covering yarns, it may be composed of covering yarns in which the ratio of colored to colorless is adjusted according to each use environment. Further, even in the case of coloring, various colors may be mixed, or the mixing ratios may be different from each other.

The covering yarn is made of nylon yarn or polyester yarn. Also, it is preferable to have 1 to 20 strands, but more or less strands may be made to suit the environment in which high-strength functional seals are used. The yarn thickness of the covering yarn is preferably 20 deniers or more, but a thickness suitable for the environment in which the high strength functional yarn is used can be used.

The high-strength functional yarn of the present invention described above is a yarn obtained by twisting a covering yarn by a braiding method to a core yarn half yarn, which is a complement to the weak yarn having only a half strength. Examples of application of such a high-strength functional yarn may vary, but can be used as a sewing thread as an example. In order to be used as a sewing thread, it should not be cut off well, and it is desirable not to lose the property of reflex reflection. The high-strength functional yarn, which is obtained by folding the covering yarn by the core yarn half yarn in the fact, has excellent abrasion, tensile, and tear characteristics as compared with the yarns which are yarn yarns of S and Z, More. That is, the yarn twisted into the S and Z characters loses the reflex reflection property of the half yarn, but when the yarn is twisted by the braiding method as in the present invention, the luminance characteristic is rather improved. In addition, the thickness of the high-strength functional yarn becomes constant by the braiding continuous yarn, the hardness characteristic becomes better, and the high-strength functional yarn becomes soft (soft property). Also, the problem of falling fine powder in the semi-finished product can be solved by the braiding method.

On the other hand, in order to use the high-strength functional yarn according to the present invention as a sewing thread, the yarn must be easily inserted into the needle ears even after cutting the yarn with scissors. For such a function, in the present invention, the covering yarn is twisted in a braided manner and then the thin film is coated. High-performance functional seals can be made and then silicon or polyurethane coatings can be made to produce high-strength functional seals with strong strength and retroreflective properties.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to be exemplary only and are not restrictive of the invention, It will be possible.

The configuration and functions of the above-described components have been described separately from each other for convenience of description, and any of the components and functions may be integrated with other components or may be further subdivided as needed.
