본 발명은 사출용 폴리프로필렌(Polypropylene; 이하 P P라 한다)과 고밀도 폴리에틸렌(High Density Polyethylene : 이하 HDPE라 한다)을 원료로 사용하고 이들을 혼합하여 만들어지는 중공섬유 제조방법에 관한 것이다.The present invention relates to a hollow fiber manufacturing method that is made by mixing polypropylene (Polypropylene; hereinafter referred to as P P) and high density polyethylene (hereinafter referred to as HDPE) as a raw material and mixing them.

중공섬유는 가볍고 부품성이 풍부하며, 함유공기가 많아, 단열효과 및 보온성이 우수하며, 중공부에서의 빛의 난반사효과 때문에 불투명감이 높으며, 중공부의 모세관 작용에 의해 흡수성, 투수성이 우수한 특징을 가지고 있어 인테리어용 섬유, 카핏, 일반의복용 뿐만 아니라 의료용으로까지 널리 이용되고 있다.Hollow fiber is light and abundant in parts, contains a lot of air, has excellent heat insulation effect and heat retention, high opacity due to light reflection effect of hollow part, and excellent absorbency and water permeability by capillary action of hollow part. It is widely used not only for interior textiles, carpets and general clothing but also for medical use.

그러나 이러한 중공섬유는 대부분이 폴리에스테르 섬유로서 제조되어 지거나 국내 공개특허공보 공개번호 88-4141호(1988.6.1)에 나타난 바와 같이 PP에 LLDPE(선형 저밀도 폴리에틸렌)가 분사상으로 퍼지는 방식으로 배열된 2성분섬유로 제조되어 있으므로, 제품자체의 가격이 고가일 뿐만 아니라 고품질의 제품에만 사용되어지는 것이었다.However, these hollow fibers are mostly made of polyester fibers or arranged in such a way that LLDPE (linear low density polyethylene) is spread in the spray phase in PP as shown in Korean Patent Publication No. 88-4141 (1988.6.1). Since it is made of two-component fiber, the price of the product itself is not only expensive but also used only for high quality products.

본 발명은 상기와 같은 사정을 고려하여 원료의 가격이 저렴하면서도 구입 하기가 용이하고 또한 고품질을 요하지 아니하는, 즉 봉제 완구등의 속을 채우는 충진물용으로 사용되어 지는 중공섬유을 제조하는데 그 목적이 있는 것이다.In view of the above circumstances, the present invention has a purpose to produce hollow fibers that are used for filling materials, such as stuffed toys, which are cheap and easy to purchase and do not require high quality. will be.

일반적으로 PP 섬유는 폴리에틸렌 정도의 고강도와 우수한 반발탄성, 내마모성과 높은 융점을 지니면서 가격이 저렴한 반면에 HDPE섬유는 나일론에 유사한 강도와 내마모성등이 우수한 특성을 가지고는 있으나 낮은 융점과 반발탄성이 낮은 단점이 있다.In general, PP fiber has low strength and high resilience, high resilience, wear resistance and high melting point, and low price while HDPE fiber has similar strength and wear resistance to nylon, but low melting point and low rebound elasticity. There are disadvantages.

본 발명은 상기와 같이 PP나 HDPE를 각각 단독으로 하여 제조되는 섬유가 가지는 단점을 서로 보완하여 제조비용과 제품가격이 저렴한 중공섬유을 제조하는데도 그 목적이 있는 것이다.The present invention is to compensate for the disadvantages of the fiber produced by using each of PP and HDPE alone as described above, and to provide a hollow fiber with low manufacturing cost and product price.

상기와 같은 목적은 PP에 산화방지제, 자외선 흡수제등을 약간량 배합하여서 되는 사출용 PP와 HDPE를 혼합하여 용융방사하여 중공섬유을 제조함에 있어서 압출기내에의 부분에 따라 온도를 순차적으로 상승시켜 압출된 중공섬유를 제1및 제2단계의 물연신을 실시함을 특징으로 하는 것이다.The purpose of the above is to produce a hollow fiber by mixing and spun-melting PP and HDPE for injection, in which a small amount of an antioxidant, ultraviolet absorber, etc. is mixed with PP, and the hollow fiber extruded by sequentially raising the temperature according to the part in the extruder It is characterized in that the fibers are subjected to water stretching in the first and second stages.

이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명은 사출용 PP와 HDPE를 혼합하여 호퍼를 통하여 공급하고 압출기에서 용융 압출하여 헤드와 다이스를 거쳐 다이스의 압출공을 통하여 중공섬유를 제조하는 것이다. 즉, 사출용 PP와 HDPE의 혼합비율에 꼭 한정을 둘 필요가 없으나 둘중에 어느 하나의 수지 중량 조성비가 80% 를 넘지 않는 범위내에서 결정하도록 하고 이의 범위를 벗어나면 혼합 용융물의 유동성이 저하되어 압출 및 방사성이 저하되며, 이러한 기술은 이미 공지되어있는 것으로 본 발명에서는 상기와 같은 공지의 사출용 폴리프로필렌과 고밀도 폴리에틸렌이 혼합된 중공섬유의 제조방법에서 압출기 및 물연신시의 온도를 하기될 온도로 하여 중공섬유를 제조하는 것이다.The present invention mixes PP for injection and HDPE, feeds through a hopper and melt-extrudes in an extruder to produce hollow fibers through an extrusion hole of a die through a head and a die. That is, it is not necessary to limit the mixing ratio of the injection PP and HDPE, but the resin weight composition ratio of any one of them should be determined within the range not exceeding 80%. Extrusion and radioactivity are lowered, and such a technique is already known. In the present invention, the temperature at which the extruder and the water are drawn in the manufacturing method of the hollow fiber mixed with the above-mentioned injection polypropylene and high-density polyethylene is It is to produce a hollow fiber.

제1도는 본 발명의 제조공정을 설명하기 위한 개략도로서 혼합용융물이 이송스크류(2)에 의해 이송되도록 하는 압출기(1)는 제1부분(A)의 온도를 220℃로 하여 제1부분(B), 제3부분(C), 제4부분(D)의 온도를 10~20℃ 정도씩 높게 설정하여 각각 230℃, 250℃, 270℃가 되도록 하여 용융성과 유동성을 높이도록 하였다. 즉, 상기 압축기(1)는 실제길이가 1.5m 정도로써 상기 제1부분(A), 제2부분(B), 제3부분(C)및 제4부분(D)의 내측에 각각 전기코일을 설치시키고, 상기 전기코일은 각각 제어부스에 전기적으로 연결되며, 상기 제어부스에는 상기 각각의 코일의 온도를 조절할 수 있는 온도조절기를 구비하고 있어 온도조절기를 조절하여 압축기(1)의 각 부분(A)(B)(C)(D)의 온도를 급격히 상승시켜 수지를 용융시키지 않고 점차적으로 온도를 상승시키는 것은 수지의 압축기(1)의 입구 즉 제1부분(A)에서부터 수지가 완전용융되면 용융된 수지는 공급되는 수지의 압력에 의해 압축기(1)를 통하여 압축되지 않고 역류되어 중공섬유를 제조할 수 없기 때문에 제1 및 제2부분(A)(B)에서는 공급되는 수지를 약간만 용시켜 공급되는 수지의 압력에 의해 압축기(1)를 통하여 밀려나가면서 외표면이 약간씩 용융되어 윤활작용 하므로써 압축기(1)의 내측면과의 마찰력을 최소화시켜 유동성을 현저히 향상시킬 수 뿐만 아니라 제3부분(C)에서 수지를 실질적으로 용융시키기 시작하고 제4부분(D)에서 수지가 완전히 용융된 상태로 되는 것이고 제1 및 제2부분(A)(B)을 통하여 압축되어지는 수지에 의해 역류되지 않고 유로를 따라 헤드(3)로 유동될 수 있는 것이다.1 is a schematic view for explaining the manufacturing process of the present invention, the extruder 1, which allows the mixed melt to be conveyed by the conveying screw 2, the first part (B) at a temperature of 220 ° C ), The third portion (C), the fourth portion (D) was set to a temperature of about 10 to 20 ℃ high so as to be 230 ℃, 250 ℃, 270 ℃ respectively to increase the meltability and fluidity. That is, the compressor 1 has an actual length of about 1.5 m and an electric coil is respectively provided inside the first part A, the second part B, the third part C, and the fourth part D, respectively. The electric coils are electrically connected to the controllers, and the controllers are provided with temperature controllers for controlling the temperature of the respective coils. (B) (C) (D) to increase the temperature rapidly without melting the resin, gradually increasing the temperature is melted when the resin is completely melted from the inlet of the compressor (1), that is, the first part (A) of the resin The supplied resin is flowed back through the compressor 1 without being compressed by the pressure of the supplied resin, so that the hollow fiber cannot be manufactured. It is pushed out through the compressor 1 by the pressure of the resin By slightly melting and lubricating, the frictional force with the inner surface of the compressor 1 can be minimized to not only improve fluidity, but also start to melt the resin substantially in the third part C and then to the fourth part D. In this case, the resin is in a completely molten state and can flow to the head 3 along the flow path without being flowed back by the resin compressed through the first and second portions (A) and (B).

이후 헤드(3)의 온도를 250℃정도로 하고 다이스(4)의 온도를 240℃정도로 하여 방사된 섬유는 중공섬유(중공섬유가 만들어지는 과정은 기공지된 사항이므로 생략함)상으로 이루어지면서 퀀칭 챔버를 거쳐 냉각되고 유제를 부여한 후 통(桶)형상의 용기에 일정량이 모아지면, 이의 중공섬유를 물의 온도를 45~50℃로 하는 제1물연신(10)과 제2물연신(20)을 실시하여 총연신 배율을 4~5배가 되도록 한후에 크림프를 부여하고 건조기에서 건조하여 일정길이로 절단하여 스테이플상으로 제조하는 것이다.After the temperature of the head (3) to about 250 ℃ and the temperature of the die (4) to about 240 ℃, the fiber is quenched while made of hollow fibers (the process of making the hollow fiber is omitted because it is a pore known matter) After cooling through a chamber and adding an emulsion, a certain amount of water is collected in a cylindrical container, and the hollow fibers thereof are first water drawn 10 and second water drawn 20 having a water temperature of 45 to 50 ° C. After performing the total draw ratio to 4 to 5 times to give a crimp, and then dried in a dryer to cut to a certain length to prepare a staple.

본 발명에서 제1및 제2물연신시에 물의 온도가 상기 범위의 미만이면 미연신을 초래할 수 있으며 초과하는 경우에는 과연신으로 인한 연신의 차별화가 일어나 섬유의 굵기가 균일하지 못한 결과를 초래할 수 있다.In the present invention, when the temperature of the water during the first and the second water stretching is less than the above range may result in unstretching, if exceeding, the stretching may be different due to overstretching, which may result in uneven thickness of the fiber. .

본 발명에 의하여 제조되는 중공섬유는 기존 폴리에스테르 중공사에 비하여 무게가 가볍고 원료의 구득이 용이하며 가격이 저렴하여 경제성이 높으며 특히 봉제완구등의 충진물로서는 아주 적합하게 사용될 수 있는 것이다.Hollow fiber produced by the present invention is lighter than the conventional polyester hollow fiber, easy to obtain the raw material, low cost, high economical, and particularly can be used as a filling material, such as stuffed toys.

이하 실시예를 들어 설명한다.An example is given below.
