Description

폴리에스테르와 폴리부틸렌테레프탈레이트를 함유하는 가발용 섬유{Fiber for a wig comprising PET and PBT}Fiber for a wig comprising PET and PBT}

본 발명은 가발용 섬유에 관한 것으로서, 보다 상세하게는 폴리에스테르(PET)와 폴리부틸렌 테레프탈레이트(PBT)를 함유하는 가발용 섬유에 관한 것이다.The present invention relates to fibers for wigs, and more particularly, to fibers for wigs containing polyester (PET) and polybutylene terephthalate (PBT).

인조 가발용 섬유를 만드는 재료(Resin)로서는 PVC 수지, MODACRYL 수지, P.P (폴리프로필렌) 수지, PET (폴리에스테르) 수지 등이 사용되고 있는데, 이중에서도 PET 수지로 만든 가발용 섬유는 탄성율 양호, 색상 및 광택성 양호, 열고착후 세팅이 잘되는 장점으로 인해 종래부터 많이 사용되고 있다.PVC resin, MODACRYL resin, PP (polypropylene) resin, PET (polyester) resin, etc. are used as materials for making artificial wig fibers. Of these, wig fibers made of PET resin have good elasticity, color and Good gloss, good setting after opening and closing has been widely used in the past.

그러나, PET 수지는 강성이 너무 강하여 다소 부드러운 느낌을 주지 못하며, 컬링시에 섬유의 끝이 피부를 자극하는 문제점이 있었다. 그러므로, 다른 수지를 혼합하여 가발용 섬유에 다소 부드러운 느낌을 줄 필요가 있어왔다.However, PET resin is too strong to give a somewhat soft feeling, there was a problem that the end of the fiber during the curling irritate the skin. Therefore, it has been necessary to mix different resins to give the wig fibers a somewhat soft feel.

그러나, 각 수지끼리는 용융온도가 상이하여 골고루 분산이 안되어 압출 방사가 안됨으로 인해 서로 잘 융합하지 않는 문제점이 있었으며, 잘 융합되는 수지라 할지라도 혼합비율에 따라 상이한 방사성 및 원사 물성 차이를 발생시키는 문제점이 있었다.However, there is a problem that each resin does not fuse well with each other because the melting temperature is different and not evenly distributed, so that extrusion spinning is not, and even if the resin is well fused, there is a problem of generating different radioactive and yarn property differences depending on the mixing ratio. There was this.

본 발명자들은 상기 문제점들을 해결하기 위해 예의 노력을 한 결과, PET 수지와 전혀 성질이 상이한 P.P, 나일론, PVC 등의 수지와는 혼합이 불가능하므로, PET와 공중합 화합물의 혼합이 필요한 바, 기존 공중합 화합물로서는 PBT (폴리부틸렌 테레프탈레이트), PTT (폴리트리메틸렌 테레프탈레이트), PNT (폴리나프탈레이트 테레프탈레이트) 등이 있으나, PTT는 섞었을 경우 너무 유연한 성질을 나타내고, PNT는 너무 강성이 강해지는 경향이 있으며, PBT가 가장 인모에 유사한 유연성을 나타냄을 발견하고 본 발명을 완성하기에 이르렀다.The present inventors have made diligent efforts to solve the above problems, and as a result, it is impossible to mix with resins such as PP, nylon, and PVC, which have completely different properties from PET resins, and thus a mixture of PET and copolymer compounds is required. Examples of these include PBT (polybutylene terephthalate), PTT (polytrimethylene terephthalate), and PNT (polynaphthalate terephthalate), but PTT is too flexible when mixed, and PNT tends to be too rigid. It has been found that PBT exhibits the most flexibility similar to human hair and has led to the completion of the present invention.

따라서, 본 발명은 전술한 바와 같은 종래의 가발용 섬유에 사용되는 PET 수지의 문제점을 해결하기 위한 것으로, PET 수지의 양호한 탄성, 색상 및 광택성 및 세팅능력등의 장점을 유지하면서도, 수지의 강성을 감소시켜 인모와 유사한 부드러운 느낌을 주는 가발용 섬유를 제공함을 목적으로 하고 있다.Accordingly, the present invention is to solve the problems of the PET resin used in the conventional wig fibers as described above, while maintaining the advantages such as good elasticity, color and gloss and setting ability of the PET resin, the rigidity of the resin The purpose of the present invention is to provide a fiber for a wig giving a soft feeling similar to human hair.

도 2는 본 발명의 가발용 섬유의 컬링시의 유연성을 측정하기 위한 실험의 설명도이고,2 is an explanatory diagram of an experiment for measuring the flexibility of curling fibers of the wig of the present invention,

도 3은 본 발명의 가발용 섬유의 유연성 실험 결과를 나타내는 그라프이다.Figure 3 is a graph showing the results of the flexibility of the fiber for the wig of the present invention.

전술한 목적을 달성하기 위해 본 발명에서 제공하는 가발용 섬유는, 40 내지 70 중량%의 PET와 30 내지 60 중량%의 PBT를 함유하는 것을 특징으로 한다.In order to achieve the above object, the fiber for wigs provided by the present invention is characterized by containing 40 to 70% by weight of PET and 30 to 60% by weight of PBT.

본발명의 가발용 섬유에서, 30 중량% 미만의 PBT를 함유하는 경우에는 부드러워지지가 않고, 60 중량% 초과의 PBT를 함유하는 경우에는 너무 부드러워 처지게 된다. 본 발명의 가발용 섬유는 바람직하게는 40 중량%의 PET와 60 중량%의 PBT를 함유한다.In the fiber for the wig of the present invention, when it contains less than 30% by weight of PBT, it is not soft, and when it contains more than 60% by weight of PBT, it is too soft to sag. The fiber for the wig of the present invention preferably contains 40% by weight of PET and 60% by weight of PBT.

본 발명의 혼합 가발용 섬유를 만들기 위해, 본 발명자들은 PBT와 PET를 직접 혼합하여 용융방사하여 본 결과 용융온도 차이가 너무 커서 (10 ∼ 25 ℃), 방사가 잘 되지 않았다.In order to make the fiber for the mixed wig of the present invention, the present inventors directly melted and spun the PBT and PET as a result of the melting temperature difference is too large (10-25 ℃), the spinning was not good.

따라서, 본 발명의 혼합 가발용 섬유를 제조하는 방법으로서, PBT와 PET를 1차 용융 압출하고, 이를 펠렛(pellet)화한 후, 다시 2차로 용융 방사하는 방법을 채택하였으며, 그 결과 쉽게 방사할 수 있었다.Therefore, as a method of manufacturing the fiber for the mixed wig of the present invention, a method of primary melt extruding PBT and PET, pelletizing it, and then melt spinning again is adopted. there was.

이때, 압출기의 온도는 260 내지 280 ℃, 압출기 압력은 50 내지 100 Kg/cm2이 바람직하다.At this time, the temperature of the extruder is 260 to 280 ℃, the extruder pressure is preferably 50 to 100 Kg / cm 2 .

이하, 본 발명의 구체적인 실시예들을 들어 본 발명을 더욱 상세히 설명하나, 본 발명의 보호범위가 이들 실시예에 한정되도록 해석되어져서는 안될 것이다.Hereinafter, the present invention will be described in more detail with reference to specific embodiments of the present invention, but the protection scope of the present invention should not be interpreted to be limited to these embodiments.

본 발명의 가발용 섬유의 유연성 효과를 시험하기 위하여 다음과 같은 시험 방법은 실시하였다.In order to test the flexibility effect of the fiber for the wig of the present invention the following test method was carried out.

1) 비 컬링시의 유연성 시험 방법1) Test method of flexibility in non-curling

도 1에 도시된 바와 같이, 같은 굵기 (50 D × 120 × 10 = 60000 Denier), 같은 길이 (10 cm)의 섬유의 한쪽 끝을 수평하게 잡고 다른 쪽 끝이 밑으로 처진 길이(A)를 측정하였다. 길이(A)가 클수록 가발용 섬유는 더 부드럽다.As shown in Fig. 1, holding one end of a fiber of the same thickness (50 D × 120 × 10 = 60000 Denier), the same length (10 cm) horizontally and measuring the length (A) where the other end sags downwards. It was. The larger the length A, the softer the wig fibers.

2) 컬링시의 유연성 시험 방법2) Flexibility test method when curling

도 2에 도시된 바와 같이, 직경 15 cm 굵기의 AL 파이프에 60000 D의 섬유를 돌려 감고, 90 ℃에서 45 분간 세팅한 후, 10 일 경과 후 늘어진 길이(B)를 측정하였다. 길이 (B)가 클수록 가발용 섬유는 더 부드럽다.As shown in FIG. 2, a 60000 D fiber was wound around an AL pipe having a diameter of 15 cm, set for 45 minutes at 90 ° C., and then the length B after 10 days was measured. The larger the length (B), the softer the wig fibers.

3) 실시예 1 내지 8의 시험 결과3) Test result of Examples 1-8

도 3에 도시된 바와 같이, PBT 30 % 혼합까지는 길이 (A) 및 길이 (B)에 크게 변동이 없으며, PBT 60 % 혼합까지는 길이 (A) 및 길이 (B)가 적당하여 부드러운 상태를 유지하였으며, PBT 60%를 초과하면 길이 (A) 및 길이 (B)가 급격히 증가하여 처지는 상태가 증가하였다.As shown in FIG. 3, the length (A) and the length (B) were not significantly changed until the PBT 30% mixing, and the length (A) and the length (B) were moderately maintained until the PBT 60% mixing. When the PBT exceeds 60%, the length (A) and the length (B) increase rapidly and sag increases.

따라서, 본 발명에 따른 가발용 섬유는 종래의 PET 수지의 강성 문제점을 해결하여, PET 수지의 양호한 탄성율, 색상 및 광택성 및 세팅능력등의 장점을 유지하면서도, 인모와 유사한 부드러운 느낌을 주는 뛰어난 효과를 나타낸다.Therefore, the fiber for the wig according to the present invention solves the rigidity problem of the conventional PET resin, while maintaining the advantages such as good elastic modulus, color and gloss and setting ability of the PET resin, excellent effect of giving a soft feeling similar to human hair Indicates.
