Description

폴리에스테르 인조 모발용 원사{Polyester Filament for Synthetic Hair}Polyester Filament for Synthetic Hair

발명의 분야Field of invention

본 발명은 인조 모발용 원사에 관한 것이다. 보다 구체적으로 본 발명은 타원형 섬유단면에 타원형 중공부를 형성하도록 특별히 제조한 중공형방사구금장치에 의하여 유연성, 경량성 및 부품성을 개선한 폴리에스테르 인조모발용 원사에 관한 것이다.The present invention relates to a yarn for artificial hair. More specifically, the present invention relates to a yarn for polyester artificial hair, which improves flexibility, lightness, and parts by a hollow spinneret device specially manufactured to form an elliptical hollow portion in an elliptical fiber cross section.

발명의 배경Background of the Invention

인조모발은 난연성을 가져야 하고, 광택성이 양호하여야 하고, 염색성이 양호하여야 하고, 촉감이 부드럽고 유연하여야 하며, 컬(curl)을 형성하는 특성과 형성된 컬의 형태를 잘 유지하려는 특성이 있어야 하고, 가벼워야 하는 등의 물성을 요구하고 있다.Artificial hair should have flame retardancy, good gloss, good dyeing, soft touch and softness, good curl formation and good curl shape. It requires physical properties such as light weight.

폴리에스테르 원사는 상기와 같은 인조모발이 필요로 하는 물성을 충족하지 못하고 있기 때문에 이제까지 인조모발용 원사로 광범위하게 이용되지 못하고 있는 실정이다.Polyester yarns have not been widely used as yarns for artificial hairs because they do not satisfy the physical properties required by the above-described artificial hairs.

폴리에스테르 인조모발 원사는 폴리머의 화학구조에서 기인하는 분자구조의 강직성으로 인하여 영율(Young's modulus)이 크기 때문에, (1) 인조모발이 필요로 하는 유연성과 드레이프(drape)성이 부족하여 형성된 컬(curl)이 부자연스럽고, (2) 피부와 접촉시 촉감이 좋지 못하며, (3) 폴리머의 높은 결정성으로 인하여 섬유표면에 입사된 광의 굴절율이 커서 금속성 광택이 나고, (4) 비중이 1.38-1.40으로 인모(人毛) 대비 단위 중량당 약 10% 정도 더 무겁기 때문에 두피의 피복 능력(covering)이 떨어져 경량성을 요구하는 가발사로서 적합하지 않은 문제점이 있다.Since polyester artificial hair yarn has a high Young's modulus due to the rigidity of the molecular structure resulting from the chemical structure of the polymer, (1) curls formed due to the lack of flexibility and drape that artificial hair needs. curl) is unnatural, (2) poor touch when in contact with the skin, (3) high refractive index of the light incident on the fiber surface due to the high crystallinity of the polymer, resulting in a metallic luster, and (4) specific gravity 1.38-1.40 As it is about 10% heavier per unit weight than human hair, there is a problem in that the covering capacity of the scalp is not suitable as a wig that requires lightness.

상기와 같은 문제점을 해결하기 위하여, 다음과 같은 연구가 진행되었지만, 아직까지 만족스러울 만큼 성공적이지 못하였다.In order to solve the above problems, the following studies have been conducted, but have not been satisfactorily successful.

폴리에스테르 인조모발 원사의 유연성과 촉감을 개선하기 위하여, 폴리에스테르 폴리머 분자에 신축성을 갖는 성분을 상대적으로 많이 함유하고 있는 폴리부틸렌 테레프탈레이트(PBT)와 같은 수지를 일정량 혼합하여 원형단면 방사구금을 사용하여 방사하여 개선하는 방법이 있지만, 이 방법은 고가의 PBT 수지를 사용함으로 인하여 섬유의 원가가 상승되어 가격경쟁력이 떨어진다.In order to improve the flexibility and feel of polyester artificial hair yarn, a circular cross-section spinneret is mixed by mixing a certain amount of a resin such as polybutylene terephthalate (PBT), which contains a relatively large amount of elastic components in polyester polymer molecules. There is a method to improve the spinning by using, but this method is expensive due to the use of expensive PBT resin, the price competitiveness is lowered.

폴리에스테르 수지에 실리카(silica) 미립자 혹은 산화티탄(TiO2)을 혼합하여 섬유 내에 미세하게 분산시켜 개선하는 방법이 있지만, 이 방법에서는 응집되어 커진 실리카 미립자가 용융방사공정에서 폴리머 필터를 막아 폴리머의 흐름을 방해하여 균일한 섬유를 제조하기 어렵고 노즐구멍을 막는 현상이 발생되어 노즐교체 및 필터교체주기가 짧아져서 생산성이 현저히 감소되는 문제가 있다.There is a method of mixing silica fine particles or titanium oxide (TiO 2 ) with a polyester resin to finely disperse them in the fiber and improving them. However, in this method, agglomerated silica fine particles block the polymer filter in the melt spinning process to obtain a polymer. There is a problem that it is difficult to produce uniform fibers by obstructing the flow and clogging the nozzle hole, so that the cycle of nozzle replacement and filter replacement is shortened and productivity is significantly reduced.

섬유 축방향으로 삼각단면 섬유내부에 중공(hollow) 단면을 형성하여 경량성을 개선하려는 시도가 있었지만, 이 방법은 오히려 금속성 광택이 증가하고 섬유끼리의 면접촉(面接觸)이 일어남으로써 집속성이 증가하여 정모(整毛)공정에서 해클링(hackling) 트러블이 발생하여 작업능률이 떨어지는 문제가 수반된다.Attempts have been made to improve the lightness by forming hollow cross sections in the triangular fiber in the axial direction of the fiber, but this method has increased the metallic luster and surface contact between the fibers. Increasingly, hackling troubles occur in the hair-machining process, resulting in a decrease in work efficiency.

섬유단면에 원형의 중공을 형성하는 경우, 쌍침 미싱 공정에서 잘 굽혀지지 않으며 정교한 작업이 어려워지는 문제가 있다.In the case of forming a circular hollow in the cross-section of the fiber, there is a problem that it is difficult to bend in the twin needle sewing process and difficult to precise work.

발명의 구체예에 대한 상세한 설명Detailed Description of the Invention

본 발명자는 폴리에스테르 인조모발용 원사가 갖는 종래의 문제점을 예의 분석하고, 섬유의 단면형태와 인조모발 원사의 물리적인 특성과의 상관관계를 규명하여 타원형 중공단면을 형성시키는 기술을 개발함으로서 종래의 문제점을 해결하는데 성공하였다.MEANS TO SOLVE THE PROBLEM The present inventor has analyzed the conventional problem which the yarn for polyester artificial hair has, and developed the technique which forms the elliptical hollow cross section by identifying the correlation between the cross-sectional shape of a fiber and the physical characteristic of an artificial hair yarn, and has conventional problem. Succeeded in solving the problem.

제1도는 본 발명의 실시예에 따라 제조된 폴리에스테르 인조 모발용 원사의 단면을 나타낸 확대사진이다.1 is an enlarged photograph showing a cross section of a yarn for polyester artificial hair manufactured according to an embodiment of the present invention.

제1도에 도시된 바와 같이, 본 발명의 폴리에스테르 인조모발용 원사는 섬유단면형태가 타원형으로, 그 내부에 타원형의 중공(hollow)이 형성된다. 상기 섬유단면의 타원형 및 중공의 타원형에서 장축(a)과 단축(b)의 길이비가 약 1.2-5.0 의 범위이고, 중공율은 5-50 %의 범위인 것이 바람직하다. 장축(a)과 단축(b)의 길이비가 약 1.5-2.5 의 범위이고, 중공율은 10-25 %의 범위인 것이 더 바람직하다. 본 발명의 폴리에스테르 인조모발용 원사는 섬도가 약 30-90 데니어인 것이 바람직하다.As shown in FIG. 1, the yarn for polyester artificial hair of the present invention has an elliptical fiber cross-section, and an elliptical hollow is formed therein. The length ratio of the long axis (a) and the short axis (b) in the oval and hollow oval of the fiber section is in the range of about 1.2-5.0, and the hollow ratio is preferably in the range of 5-50%. More preferably, the length ratio of the major axis (a) and minor axis (b) is in the range of about 1.5-2.5, and the hollow ratio is in the range of 10-25%. The yarn for the polyester artificial hair of the present invention is preferably fineness of about 30-90 denier.

본 발명에 다른 폴리에스테르 인조모발용 원사는 섬유의 타원단면에서 장축(a)과 단축(b)의 길이비(a/b)는 매우 중요하다. 왜냐하면 이 장축(a)과 단축(b)의 길이비(a/b)는 섬유의 유연성향상, 겉보기 섬도의 증가에 따른 피복성 향상, 촉감개선, 광택개선, 중공부분만큼 단위 중량당 섬유의 가닥수가 증가하여 섬유의 경량화에 영향을 미치기 때문이다.The polyester yarn for polyester artificial hair according to the present invention is very important for the length ratio (a / b) of the long axis (a) and the short axis (b) in the elliptical cross section of the fiber. This is because the length ratio (a / b) of the long axis (a) and the short axis (b) increases the flexibility of the fiber, improves the coating property by increasing the apparent fineness, improves the feel, improves gloss, and strands of the fiber per unit weight by the hollow part. This is because the number increases, which affects the weight reduction of the fiber.

장축(a)과 단축(b)의 길이비(a/b)가 증가하면 유연성이 증가하고 겉보기 섬도가 증가되므로 피복성은 증가하며 금속성 광택이 나타나는 경향이 있으며 섬유의 비틀림에 의하여 불균일한 난반사가 발생할 수도 있다. 반면, 길이비(a/b)가 감소하면 유연성이 떨어지고 피복성이 감소된다. 따라서, 본 발명에서 가발에 사용하는 타원 중공섬유단면은 가발의 용도에 따라서 다르나 길이비(a/b)가 1.2-5.0 범위인 것이 적합하고 더 바람직하기로는 일반 범용의 가발의 경우 1.5-2.5 범위이다.Increasing the length ratio (a / b) of the long axis (a) and short axis (b) increases the flexibility and the apparent fineness, so that the coating property increases, the metallic luster tends to appear, and uneven diffuse reflection occurs due to the twisting of the fiber. It may be. On the other hand, if the length ratio a / b is reduced, the flexibility is reduced and the coating property is reduced. Therefore, the elliptic hollow fiber cross section used for the wig in the present invention varies depending on the use of the wig, but the length ratio (a / b) is preferably in the range of 1.2 to 5.0, and more preferably in the range of 1.5 to 2.5 for general general purpose wigs. to be.

본 발명에서 사용한 방사구금은 노즐 구멍을 2분할하여 제작된 특수한 중공노즐을 사용하였다. 타원형 단면의 장축과 단축의 길이비(a/b)는 방사구금온도, 후드(hood) 온도, 원료수지의 용융점도에 어느 정도 영향을 받는다. 이러한 점을 감안하여 노즐을 설계하여야 하며, 최종적으로 중공섬유단면의 길이비(a/b)가 1.2-5.0의 범위가 되도록 하여야 한다.The spinneret used in the present invention used a special hollow nozzle manufactured by dividing the nozzle hole into two. The length ratio (a / b) of the major axis and minor axis of the elliptical cross section is influenced to some extent by the spinneret temperature, the hood temperature, and the melt viscosity of the raw material resin. Considering this point, the nozzle should be designed and finally the length ratio (a / b) of the hollow fiber cross section should be in the range of 1.2-5.0.

본 발명의 가발용 필라멘트 섬유는 다른 형태의 섬유단면을 갖는 필라멘트와 혼합하여 사용할 수 있는데, 이 경우 본 발명의 가발용 필라멘트 섬유가 약 10-70 %로 함유되도록 혼합하여 방사한다. 예를 들어, 하나의 노즐에 본 발명에 따른 타원형의 중공을 갖는 타원형 단면의 원사가 약 10-70 %로 함유되도록 설계하고, 나머지는 라운드(round) 단면 또는 기타의 다른 모양의 단면을 갖도록 설계하여 혼합형태의 가발용 필라멘트 섬유를 제조할 수 있다.The wig filament fiber of the present invention can be mixed with the filament having a different cross-section of the fiber, in which case the wig filament fiber of the present invention is mixed and spun to contain about 10-70%. For example, one nozzle is designed to contain about 10-70% yarn of elliptical cross section with an elliptical hollow according to the present invention, and the rest is designed to have a round cross section or any other shaped cross section. To produce a mixed form of filament fibers for wigs.
