Abstract

The present invention relates to retro-reflection yarn having a retro-reflection function and a method for manufacturing the same. According to the present invention, the retro-reflection yarn having a retro-reflection function is manufactured. The retro-reflection function is maintained for a long time by preventing retro-reflection materials, which are fine glass beads coated on the yarn, from escaping the yarn. The retro-reflection yarn has good weaving properties as tensile strength is increased. In addition, durability of woven fabric manufactured by using the retro-reflection yarn is excellent. The retro-reflection yarn can be used for various purposes such as sewing yarn. The retro-reflection yarn having a retro-reflection function is manufactured by obtaining a retro-reflection film by coating a film with the fine glass beads, obtaining film yarn having a retro-reflection function by cutting the retro-reflection film, and braiding transparent mono-filament yarn on the outside of the film yarn which is used as core yarn. Accordingly, the core yarn, coated with the materials performing the retro-reflection function, is located inside the braiding yarn. Consequently, the retro-reflection yarn can be protected from friction of the outside, and the tensile strength of the retro-reflection yarn can be increased.

Description

재귀반사기능을 갖는 재귀반사실 및 그 제조방법{RETRO-REFLECTION YARN AND ITS MANUFACTURING METHOD}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retroreflector having a retroreflective function,

본 발명은 재귀반사기능을 갖는 재귀반사실 및 그 제조방법에 관한 것으로서, 특히 재귀반사기능을 만족하면서 강도가 우수하고 재귀반사기능이 장기간 지속될 수 있게 한 것이다.The present invention relates to a reflexive substance having a retroreflective function and a method of manufacturing the same, and more particularly, to a retroreflective lens which satisfies a retroreflective function and has excellent strength and a retroreflective function for a long period of time.

재귀반사란, 입사한 광선을 광원으로 그대로 되돌려 보내는 반사로서, 빛이 어느 각도로 들어오더라도 광원의 방향으로 빛을 반사시키게 된다.Retroreflective is a reflection that sends incident light back to the light source, and reflects the light in the direction of the light source even if the light enters at any angle.

이러한 재귀반사원리는 스포츠의류나 용품, 신발, 야간안전용품 등 다양한 분야에 적용사용되고 있으며, 주로 제품 외면에 재귀반사기능을 갖는 소재(미세한 유리구슬)를 코팅하여 사용하게 된다.Such a reflex reflection principle is applied to various fields such as sports clothes, articles, shoes, night safety articles, etc., and the material (fine glass beads) having a retroreflective function is coated on the outer surface of the product.

또한 재귀반사소재를 필름에 코팅한 다음 필름을 잘게 절단하여 실을 제조하고, 상기 실로 직물을 제직하여 제품에 적용하는 경우도 있다.There is also a case where a retroreflective material is coated on a film and the film is finely cut to produce a yarn, and the yarn is weaved to be applied to a product.

그러나 상기한 재귀반사제품의 경우 재귀반사소재가 단순히 제품 외면에 코팅되어 있는 형태로서 사용중 마찰 등의 외부요인에 의해 쉽게 탈락되어 기능을 상실하게 될 뿐 아니라, 재귀반사기능을 갖는 실로 제직한 직물의 경우 강도가 취약하여 제직에 많은 어려움이 있을 뿐 아니라, 제직된 직물의 경우에도 내구성이 약하여 직물로서의 기능이 미비한 것이었다.However, in the case of the retroreflective product described above, the retroreflective material is simply coated on the outer surface of the product, and is easily lost due to external factors such as friction during use, so that the function is lost, In addition, since the fabric is weak in strength, it has many difficulties in weaving, and even in the case of the woven fabric, the durability is weak and the function as a fabric is insufficient.

이하 본 발명의 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 기술요지는 재귀반사기능을 갖는 실, 혹은 필름사를 심사로 하고, 상기 심사 외면에 투명모노필라멘트사를 브레이딩하여 심사 외면에 코팅된 재귀반사소재(미세한 유리구슬)가 보호되게 함과 동시에, 강도를 향상시킬 수 있게 한다는 것이다.The technical feature of the present invention is that a retroreflective material (fine glass beads) coated on the outer surface of the examination is protected by inserting a transparent monofilament yarn on the outer surface of the examination yarn or a yarn having a retroreflective function And at the same time, the strength can be improved.

본 발명의 실시예에서는 심사를 필름사로 적용한 경우를 기준으로 설명한다.In the embodiment of the present invention, the case where the examination is applied to the film is explained as a reference.

도 1에서와 같이 필름(10) 표면에 재귀반사기능을 갖는 미세한 유리알갱이로 된 재귀반사소재(20)를 코팅하고 건조하여, 필름(10) 표면에 재귀반사소재(20)를 고착시킨 다음, 절단기로 절단하여 필름사, 즉 심사(50)를 얻는다.A retroreflective material 20 made of fine glass grains having a reflex reflection function is coated on the surface of the film 10 and dried to fix the retroreflective material 20 on the surface of the film 10, And cut with a cutter to obtain a film yarn, that is, a screen 50.

상기 심사(50)를 보빈과 같은 권취구에 권취한 다음 브레이드기(유직기)에 설치하고, 상기 심사(20)를 브레이드기를 통과시키면서 심사(50) 외면에 투명한 모노필라멘트사로 브레이딩하여 심사(50) 외면에 브레이딩사(30)가 위치되게 함으로서, 본 발명에서 제공하고자 하는 재귀반사기능을 갖는 재귀반사실(40)의 제조가 완료되며, 제조된 재귀반사실(40)은 브레이드기 상부에 위치하는 보빈에 권취되게 하여서 된 것이다.The examination 50 is wound around a winding unit such as a bobbin and then installed in a braid machine. The examination 20 is passed through a braid machine and is then subjected to examination by a monofilament yarn The manufacturing of the recursive yarn 40 having the recursive reflection function to be provided in the present invention is completed and the produced recursive yarn 40 is formed on the upper portion of the braid base To be wound on the bobbin which is positioned.

상기에서 심사(50)로 사용된 필름사의 폭은 대략 0.25㎜정도이고, 심사(50) 외면에 위치하는 브레이딩사(30)는 투명한 모노필라멘트사로서 20~150데니어굵기의 브레이딩사(30) 4~16가닥 브레이드하게 된다.The width of the film yarn used in the examination 50 is about 0.25 mm and the braiding yarn 30 located on the outer surface of the examination yarn 50 is a transparent monofilament yarn having a braiding yarn 30 To ~ 16 braids.

그러나 필름사의 폭이나 모노필라멘트사의 굵기는 한정할 필요없이 조건에 따라 조정될 수 있다.However, the width of the film yarn or the thickness of the monofilament yarn can be adjusted according to the conditions without any limitation.

이와 같이 구성된 본 발명의 재귀반사실(40)은 재귀반사기능을 하는 심사(50)(필름(10) 표면에 미세한 유리구슬로 된 재귀반사소재(20)가 코팅된 필름사)의 외면에 투명한 모노필라멘트사로 구성된 브레이딩사(30)가 교직된 형태로 위치하게 된다.The recursive yarn fact 40 of the present invention having such a structure is obtained by forming a transparent film 40 on the outer surface of a screen 50 having a retroreflective function (a film yarn coated with a retroreflective material 20 made of fine glass beads on the surface of the film 10) A braiding yarn 30 composed of monofilament yarns is placed in the form of a weave.

따라서 재귀반사소재(20)가 코팅된 심사(50)가 투명한 모노필라멘트사로 구성된 브레이딩사(30) 내면에 위치하고 있어, 외부에서 광원이 조사되면 투명한 브레이딩사(30)를 통과하여 광선이 내부에 위치한 심사(50)의 재귀반사소재(20)와 접하게 된다.Therefore, the examination 50 coated with the retroreflective material 20 is located on the inner surface of the braiding yarn 30 composed of the transparent monofilament yarn. When the light source is irradiated from the outside, the light passes through the transparent braiding yarn 30, And comes into contact with the retroreflective material 20 of the examination 50.

심사(50)에 코팅된 재귀반사소재(20)와 접한 광선은 다시 광원의 방향으로 반사되므로 심사(50) 외면에 브레이딩사(30)가 위치하더라도 심사(50)의 재귀반사기능에는 아무런 장애가 되지 않는다.The light rays in contact with the retroreflective material 20 coated on the examination 50 are again reflected in the direction of the light source so that there is no obstacle to the retroreflection function of the examination 50 even if the braiding yarn 30 is located on the outer surface of the examination 50 Do not.

뿐만 아니라 재귀반사소재(20)가 코팅된 심사(50) 외면에 브레이딩사(30)가 위치하고 있어 외부에서 마찰이 발생하더라도 심사(50)와 직접 접촉하지 않고, 브레이딩사(30)와 마찰하여 심사(50) 외면에 코팅된 재귀반사소재(20)의 이탈을 방지하게 되므로 재귀반사기능에 장애가 되지 않는다.In addition, since the braiding yarn 30 is disposed on the outer surface of the examination 50 coated with the retroreflective material 20, the braiding yarn 30 is not in direct contact with the examination 50, It is possible to prevent the retroreflective material 20 coated on the outer surface of the lens barrel 50 from escaping.

특히 강도가 취약한 심사(50) 외면에 모노필라멘트사로 구성된 여러가닥의 브레이딩사(30)가 원통형의 교직형태로 엮어져 있어, 강신도가 향상되므로 제직성을 양호하게 하고, 또한 제직된 직물의 경우 내구성이 우수할 뿐 아니라 재봉사 등 다양한 용도로 단독사용이 가능하게 된다.In particular, since a plurality of braiding yarns 30 made of monofilament yarns are woven in a cylindrical weave shape on the outer surface of the fabric 50 having weak strength, the strength is improved and the woven fabric is improved. In addition, It is possible to use it singly for various purposes such as sewing thread.

따라서 본 발명에서 제조된 재귀반사실(40)의 경우 재봉사 등 다용도로 사용이 가능하며, 제직된 직물의 경우 스포츠용품이나 의류, 신발, 야간안전용품 등 다양한 분야에 적용하여 야간운전을 담보할 수 있게 된다.Accordingly, the recursive yarn 40 produced in the present invention can be used in a variety of applications such as sewing thread. In the case of woven fabric, it can be applied to various fields such as sports goods, clothing, shoes, .
