본 발명은 중공 멀티필라멘트 제조용 방사구금에 관한 것으로서, 더욱 구체적으로는 멀티필라멘트를 구성하고 있는 각 모노필라멘트가 이섬도(異纖渡)이고 그 중 몇 개의 모노필라멘트는 중공이 되도록 하여서 신축성과 벌키성이 우수한 스타킹용사로 활용될 수 있는 이섬도 중공 멀티필라멘트는 제조용 방사구금에관한 것이다.The present invention relates to a spinneret for manufacturing hollow multifilament, and more specifically, each of the monofilaments constituting the multifilament is a fineness, and some of the monofilaments are hollow so that the elasticity and bulkiness Isotido hollow multifilament that can be used as a superior stocking spray is related to manufacturing spinnerets.

종래의 방사구금은 토출공의 L/D(L:길이, D:직경)가 모두 동일하였기 때문에 제조된 멀티필라멘트사는 신축성과 벌키성이 부족하여서 스타킹용사로 사용하기에는 적합치 못하였다.Conventional spinnerets are not suitable for use as a stocking yarn because the manufactured multifilament yarn lacks elasticity and bulkiness because the L / D (L: length, D: diameter) of the discharge holes are all the same.

본 발명은 이섬도의 모노필라멘트들을 토출시키기 위하여 L/D을 변경시킨 토출공을 일정한 밀도로 배치하였으며, 중공의 모노필라멘트 수본을 토출시키기 위한 중공 토출공 수개를 이섬도 모노필라멘트용 토출공사이에 배열시키므로서 토출된 멀티필라멘트 수본을 토출시키기 위한 중공 토출공 수개를 이섬도 모노필라멘트용 토출공사이에 배열시키므로서 토출된 멀티필라멘트사 중에는 이섬도의 필라멘트들과 중공의 필라멘트들이 혼재되도록 하여서 신축성과 벌키성이 우수한 스타킹용 원사를 제조할 수 있도록 한 것이다.In order to discharge the monofilaments of the fine islands, the discharge holes having the L / D changed are arranged at a constant density, and the hollow discharge holes for discharging the hollow monofilament are arranged in the discharge work for the fine island monofilaments. The number of hollow discharge holes for discharging the multifilament sample discharged by arranging them is arranged in the discharging work for the island of monofilament, and the filaments of the fine island and the hollow filaments are mixed among the discharged multifilament yarns. It was to be able to manufacture this excellent yarn for stockings.

이하, 본 발명을 상세히 설명하면 다음과 같다. 토출공의 L/D를 모두 다르게 하되 L/D의 범위는 1.0

Figure kpo00002
L/D
Figure kpo00003
1.5가 되도록 한다.Hereinafter, the present invention will be described in detail. Change the L / D of the discharge hole in all but the range of L / D is 1.0

Let it be 1.5.

이때 D는 0.15(mm)

1.03(mm)이다. 만약 상기 범위를 벗어나게 되면 이섬도 모노필라멘트사들은 섬도의 차이가 너무 커서 방사 및 연신시에 절사가 많아지고 조업성이 떨어지게 된다. 토출공의 밀도(d)는 0.25(개/㎠)

1.2(개/㎠)가 되게 한다.Where D is 0.15 (mm)
Figure kpo00004
D
Figure kpo00005
1.03 (mm). If out of the above range, the fine island monofilament yarns have too large a fineness of fineness, resulting in more cutting at the time of spinning and stretching and inferior operability. The density d of the discharge hole is 0.25 (piece / cm 2)

H : 최내주상의 구금공 수(개)H: Number of detainees in most inner circle

S : 최외주와 최내주 사이의 면적(㎠)S: Area between outermost and innermost (cm2)

만약 토출공 사이의 간격이 너무 크면 경계면의 구금 배면에 폴리머의 이상 체류현상이 발생하므로 좋지않고 또 토출공 수가 너무 많으면 각 필라멘트의 균일한 냉각이 곤난하게 된다.If the spacing between the discharge holes is too large, abnormal retention of the polymer occurs on the back surface of the detention surface of the interface, which is not good. If the discharge holes are too large, uniform cooling of each filament is difficult.

O 중공 토출공의 설계조건은 다음과 같이 하였다.The design conditions of the O hollow discharge hole were as follows.

즉 실제토출면적 SR과 구금공의 면적 ST간의 비율(K)은 18

만약 상기 범위를 벗어나면 폴리머흐름의 급격한 변화로 인하여 중공이 형성되지 않거나 너무 낮아져서 좋지 않다.If it is out of the above range, it is not good that the hollow is not formed or is too low due to the rapid change of the polymer flow.

본 발명으로 제조된 이섬도 중공 멀티필라멘트를 가연가공하게 되면, 가연후 열고정시에 모노피라멘트 간의 섬도 차이에 의한 열이력의 차로 말미암아 열수축이 달라지며 또한 해연시에 열수축에 따르는 모노필라멘트간의 공극률이 증대되어서 미해연부의 발생을 어렵게 하므로 결국구 신축성 및 신축회복성에 영향을 주고 세섬도사가 벌키성에 보다 큰 영향을 미치기 때문에 태세사를 조합하면 신축성과 벌키성이 우수한 스타킹용사를 제조할 수 있게 된다.When the false fine hollow multifilament manufactured by the present invention is flammable, the heat shrinkage is changed due to the difference in the thermal history due to the difference in fineness between the monopyraments during heat setting after burning, and the porosity between the monofilaments according to the heat shrinkage during seaweed Increasingly, it is difficult to generate unsealed edges, and thus, ultimately, it affects elasticity and elasticity recovery, and sesamedosa has a greater effect on bulkiness.

또한, 스타킹으로 제편시 중공 모노필라멘트의 영향으로 가볍고 보온성이 뛰어난 스타킹이 된다.In addition, the stockings are light and excellent in thermal insulation under the influence of hollow monofilament during knitting.
