그러나 상기한 재귀반사슬리트원사는 재귀반사필름을 세로방향으로 길게 절단하여 얻은 것임에 따라 단면형상이 사각형이므로 제직시 쉽게 꼬이고 강성이 부족하여 위사 혹은 경사로만 사용하는 한계가 있다. However, since the retroreflective slit yarn is obtained by cutting the retroreflective film in the longitudinal direction, the cross-sectional shape is rectangular, so there is a limit to use only the weft or the slope because it is easily twisted when weaving and lacks rigidity.
따라서 직물의 노출면에 도트 형상으로밖에 표현되지 않아 다양한 무늬와 디자인이 불가능하고 꼬임 현상에 의해 직물에 주름이나 자국이 발생하는 문제점이 있다. Therefore, only a dot shape is expressed on the exposed surface of the fabric, and various patterns and designs are impossible, and there is a problem that wrinkles or marks occur on the fabric due to the twisting phenomenon.

본 발명은 재귀반사필름을 슬리팅 가공하여 얻은 재귀반사슬리트원사를 직물이나 편물 제직이 가능할 뿐만 아니라 자수사로도 사용 가능하도록 필라멘트원사와 합사 및 연사한 재귀반사원사 및 그 제조방법에 관한 것이다. The present invention relates to a retro-reflective yarn obtained by slitting and processing a retro-reflective film, which can be woven or knitted, as well as embroidered and filamented with filament yarn so as to be used as an embroidery yarn, and a manufacturing method thereof.
이하 본 발명의 바람직한 실시예에 따른 재귀반사원사를 첨부한 도면을 참조하여 상세하게 설명하면 다음과 같다. Hereinafter, the retroreflective yarn according to the preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 바람직한 실시예에 따른 재귀반사원사는 도 4에 도시된 바와 같이 재귀반사필름을 슬리팅 가공하여 얻은 재귀반사슬리트원사와 필라멘트원사가 합사 및 연사되어 원형에 가까운 단면형상을 가지고 직물 및 편물로 제직 가능한 인장강도를 가진 것이다. Retroreflective yarn according to a preferred embodiment of the present invention, as shown in Figure 4, the retroreflective slitting yarn and filament yarn obtained by slitting the retroreflective film as a yarn and twisted yarn having a cross-sectional shape close to the circular and It has a tensile strength that can be woven into a knit fabric.
즉, 재귀반사슬리트원사는 재귀반사필름을 길이방향을 따라 길게 절단 가공함에 따라 단면형상이 사각형상이므로 쉽게 꼬이고 인장강도가 낮은 단점이 있는데, 이를 필라멘트원사와 합사 및 연사함으로써 단면이 사각형이 아닌 원형에 가까운 형상이 되면서 꼬임도 방지되고 인장강도가 증대되어 직물이나 편물 제직 뿐만 아니라 자수사로도 사용 가능하도록 한 것이다. In other words, the retroreflective slit yarn has the disadvantage that it is easily twisted and has low tensile strength because the cross-sectional shape is rectangular in shape as the retroreflective film is cut and cut along the lengthwise direction. It is close to the shape to prevent twisting and increase the tensile strength is to be used as embroidery thread as well as woven or knitted fabrics.
한편, 재귀반사슬리트원사와 필라멘트원사는 TM(미터당 꼬임수)160~320로 연사된 것인데, 이는 상기 꼬임수보다 적으면 휘도가 떨어져 재귀반사 기능이 제대로 발휘되지 않고 상기 꼬임수보다 많으면 단면은 보다 원형에 가까워지지만 뻣뻣한 정도가 높아 제직이 곤란함이 있으므로 상기한 꼬임수 범위로 연사되는 바람직하다. On the other hand, the retroreflective slit yarn and filament yarn are twisted with TM (twist per meter) 160-320, which is less than the twist number, the luminance is lowered, and the retroreflective function is not properly exhibited. It is preferable to be twisted in the above-described twisted range because it is closer to a circle but has a high degree of stiffness, which causes difficulty in weaving.
그리고 필라멘트사는 재귀반사슬리트원사와 함께 꼬이면서 원형에 가까운 단면형상이 되도록 하고 재귀반사슬리트원사의 낮은 인장강도를 보강하여 직물 및 편물 제직이 가능한 인장강도를 갖도록 하는 것이다. The filament yarn is twisted together with the retro-reflective slit yarn to have a cross-sectional shape close to the circular shape, and to reinforce the low tensile strength of the retro-reflective slit yarn to have a tensile strength capable of weaving fabrics and knitted fabrics.
이때 필라멘트사는 나일론사, 폴리에스테르사, 폴리프로필렌사 등의 하나로 구성될 수 있다. At this time, the filament yarn may be composed of one of nylon yarn, polyester yarn, polypropylene yarn and the like.
본 발명의 바람직한 실시예에 따른 재귀반사원사의 제조방법은 도 1에 도시된 바와 같이 슬리팅 단계(S10), 합사 단계(S20), 연사 단계(S30) 및 사증 단계(S40)로 구성된다. The method of manufacturing a retroreflective yarn according to a preferred embodiment of the present invention is composed of a slitting step (S10), a weaving step (S20), a twisting step (S30), and a visa step (S40) as shown in FIG.
상기 슬리팅 단계(S10)는 원재료가 되는 도 2의 재귀반사필름을 슬리팅 가공하여 도 3의 재귀반사슬리트원사를 만드는 공정이다. 이때 재귀반사슬리트원사는 박판 형태의 재귀반사필름을 길이방향으로 길게 절단하여 만든 것이므로 사각형의 단면 형상을 가진다. The slitting step (S10) is a process of making the retroreflective slitting yarn of FIG. 3 by slitting the retroreflective film of FIG. 2 as a raw material. At this time, the retro-reflective slit yarn has a rectangular cross-sectional shape because the retro-reflective film is made by cutting the thin retroreflective film in the longitudinal direction.
상기 합사 단계(S20)는 재귀반사슬리트원사와 필라멘트원사를 하나의 보빈에 감아 합사하는 공정이다. 이때 재귀반사슬리트원사와 필라멘트원사를 보빈에 감을 때는 서로 동일한 장력을 유지하면서 보빈에 감아야 한다. The step of spooling (S20) is a process of winding the retroreflective slit yarn and the filament yarn by winding in one bobbin. At this time, when the retro-reflective slit yarn and the filament yarn are wound on the bobbin, they should be wound on the bobbin while maintaining the same tension.
상기 연사 단계(S30)는 하나의 보빈에 감긴 재귀반사슬리트원사와 필라멘트원사를 일정한 꼬임수로 연사하는 공정이다. The twisting step (S30) is a process of twisting the retro-reflective slit yarn and filament yarn wound in a single bobbin with a constant twist.
이때 2가닥의 원사를 1가닥으로 연사하는 1/2연사기를 사용하면 된다. 그리고 최대한 원형의 단면형상을 가지면서 인장강도를 증대시키고 직물 및 편물 제직이 용이하도록 뻣뻣하지 않게 TM 160~320으로 연사하는 것이 바람직하다. At this time, you can use a half-twisting machine that twists two strands of yarn into one strand. In addition, it is preferable that the yarn is twisted with TM 160-320 so as to have a circular cross-sectional shape as much as possible, increasing tensile strength and facilitating woven and knitted fabrics.
상기 사증 단계(S40)는 연사된 재귀반사슬리트원사와 필라멘트원사에 스팀을 가하여 꼬이지 않고 연사된 상태를 유지할 수 있도록 사증하는 공정이다. The visa step (S40) is a process of applying the steam to the retroreflective slit yarn and filament yarn is twisted to maintain the twisted state without twisting.
상기 사증 단계(S40)가 완료되면 도 단면이 사각형이 아닌 원형에 가까운 형상이 되면서 꼬임도 방지되고 인장강도가 증대되어 직물이나 편물 제직뿐만 아니라 자수사로도 사용 가능한 도 4의 재귀반사원사를 완성할 수 있다.When the visa step (S40) is completed, the cross-section is not a square, but a shape close to the circular twist is prevented and the tensile strength is increased to complete the retroreflective yarn of Figure 4 that can be used as embroidery thread as well as woven or knitted fabric Can be.
