Description
본 발명은 심사인 합성섬유멀티필라멘트사의 주위에 용융분사(melt blown)방식으로 제조한 극세섬유웹이 피복하고 있는 합성섬유복합사 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic fiber composite yarn coated with a microfiber web manufactured by a melt blown method around a synthetic fiber multifilament yarn, which is a screen, and a method of manufacturing the same.
본 발명에서 심사는 용융분사되는 극세섬유웹과 함께 제조시스템내에서 통상의 용융방사방식으로 제조한 합성섬유멀티필라멘트사로써 공급되는 것이다.In the present invention, the screening is supplied with a synthetic fiber multifilament yarn manufactured by a conventional melt spinning method in a manufacturing system together with a microfiber web to be melt sprayed.
종래의 합성섬유 복합사는 아래에 설명하는 바와같은 여러 가지 방법으로 제조하여 왔다.Conventional synthetic fiber composite yarns have been manufactured in various ways as described below.
즉, 이미 제사된 두 종류 이상의 필라멘트 또는 방적사를 꼬임을 주어서 합사하거나, 공기교락처리를 하거나, 와류공기중에서 서로 엉키게 하여 제조하였다. 그러나, 위 방법들은 경제적인 측면에서 제조원가가 높았으며 천연섬유와 같은 자연스러운 느낌을 부여 하는데는 미흡하였다. 또한 미국 특허 3,978,185 나 4,118,531 등에서는 합성 고분자 중합체를 용융시켜 방사하는 과정에서 고온가스를 고속으로 도입시켜서 용융분사방식으로 극세사의 웹을 제조한 다음에 이를 부직포로 제조하고 있다.That is, two or more kinds of filaments or spun yarns already prepared are twisted and spun together, or air entangled, or entangled with each other in vortex air. However, the above methods were expensive in terms of economics and insufficient to give a natural feel like natural fibers. In addition, US Pat. No. 3,978,185 or 4,118,531, etc. introduces a hot gas at a high speed in the process of melting and spinning a synthetic polymer polymer to manufacture a microfiber web in a melt spraying method, and then to manufacture it as a nonwoven fabric.
이 방법은 방사이후의 별도의 결정화 과정을 거치지 않으므로 경제적으로 매우 유리하다고 할 수 있지만 웹자체만으로는 인장강도가 낮아서 의류용 재료로 사용할 수 없었다. 또 위 발명들은 극세사의 웹으로 부직포를 제조하는 방법만을 알려주고 있을뿐 사(絲)로 제조하고저 하는 시도는 하고 있지 않다.This method is economically advantageous because it does not undergo a separate crystallization process after spinning, but the web itself cannot be used as a material for clothing because of its low tensile strength. In addition, the above inventions only show the method of manufacturing the nonwoven fabric by the microfiber web, and do not attempt to make it by the yarn.
본 발명의 목적은 미세한 모우가 표면에 현출되어서 천연섬유와 같은 촉감과 외관을 주는 합성섬유복합사를 제공하며 동시에 상기 복합사를 종래의 방법보다 저렴한 제조비용으로 제조할 수 있는 방법을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a synthetic fiber composite yarn in which fine wool is present on the surface to give the same feel and appearance as natural fibers, and at the same time, to provide a method for manufacturing the composite yarn at a lower manufacturing cost than the conventional method. .
제1도는 본 발명의 합성섬유복합사의 확대도.1 is an enlarged view of the synthetic fiber composite yarn of the present invention.
제2도는 본 발명의 합성섬유복합사의 제조공정개략도.2 is a manufacturing process schematic diagram of the synthetic fiber composite yarn of the present invention.

본 발명의 합성섬유복합사는 제1도에 표시한 바와같이 극세섬유웹(Y2)의 형태로 되어있는 모우가 합성섬유멀티팔라멘트(Y1)의 주위를 피복하고 있는 것이다.As shown in FIG. 1, the synthetic fiber composite yarn of the present invention covers the periphery of the synthetic fiber multi-pallament (Y 1 ) in the form of microfiber web (Y 2 ).
본 발명에서 심사인 합성섬유멀티필라멘트사(Y1)는 극세섬유웹(Y2)과 같은 성분이거나 다른성분의 합성고분자 중합체로 된 것이다.In the present invention, the synthetic fiber multifilament yarn (Y 1 ), which is a screening agent, is made of a synthetic polymer polymer of the same component as the microfiber web (Y 2) or of another component.
본 발명에 적용되는 합성고분자중합체로는 폴리에스테르계, 폴리마이드계, 폴리올레핀계, 폴리스틸렌 등을 들 수 있다.Examples of the synthetic polymer applied to the present invention include polyester-based, polyamide-based, polyolefin-based, and polystyrene.
본 발명의 합성섬유복합사의 제조방법을 제2도에 의거 상세히 설명하면 다음과 같다.Referring to Figure 2 according to the manufacturing method of the synthetic fiber composite yarn of the present invention in detail.
제2도는 심사인 합성섬유멀티필라멘트(Y1)를 용융방사방식으로 제조하는 경우의 제조공정개략도이다.FIG. 2 is a manufacturing process schematic diagram of manufacturing synthetic fiber multifilament Y 1 , which is a screening, by melt spinning method.
압출기(1)로부터 용융압출되는 합성고분자중합체는 중앙부분에 위치하고 있는 방사블럭(3)을 통하여 통상의 방법으로 합성섬유멀티필라멘트사(Y1)가 용융방사되며, 방사블럭(3)의 주면에 있는 용융분사장치(4)에는 압출기(2)로부터 용융압출된후 고온의 가스와 함께 합성고분자중합체의 용융물이 공급되어서 극세섬유웹(Y2) 이 용융분사(melt blown)된다.The synthetic polymer polymer melt-extruded from the extruder (1) is melt-spun in the usual way through the spinning block (3) located in the center portion of the synthetic fiber multifilament yarn (Y 1 ), the main surface of the spinning block (3) The melt spraying apparatus 4 which is melt-extruded from the extruder 2 is supplied with a melt of a synthetic polymer together with a hot gas to melt blown the ultrafine fiber web Y 2 .
용융방사된 합성섬유필라멘트(Y1)와 그 주위의 극세섬유웹(Y2)은 냉각박스(cooling box)(5)를 통과한 후에도 일부 용융고온의 상태에 있으므로 간격조정이 가능한 송출로울러(6)(7)(8)를 거치면서 압착되어 합성섬유필라멘트(Y1)의 주면에 극세섬유웹(Y2)이 피복되며, 결국 표면에 다수의 모우가 현출된 복합사가 된다.The melt-spun synthetic fiber filament (Y 1 ) and the surrounding microfiber web (Y 2 ) are in a state of some molten high temperature even after passing through the cooling box (5), so that the interval-adjustable delivery roller (6) It is pressed through the (7) (8) and the microfiber web (Y 2 ) is coated on the main surface of the synthetic fiber filament (Y 1 ), and eventually becomes a composite yarn in which a large number of cows appeared on the surface.
상기 복합사는 공급로울러(9)와 로뎃로울러(10)를 거치면서 연신된후 권취부(11)에서 권취된다.The composite yarn is stretched while passing through the supply roller 9 and the roller roller 10, and then wound in the winding unit 11.
미설명부호 12는 단열벽이다.Reference numeral 12 is an insulating wall.
[실시예 1]Example 1
표 1의 조건으로 용융방사하여 제조한 합성섬유멀티필라멘트사의 주위를 표 1의 조건으로 용융분사하여 제조한 극세섬유웹으로 피복하여서 복합사를 제조하였다.A composite yarn was prepared by covering the periphery of the synthetic fiber multifilament yarn prepared by melt spinning under the conditions of Table 1 with the microfiber web prepared by melt spraying under the conditions of Table 1.
제조된 복합사는 제1도에 도시한 바와 같이 사의 표면에 무수히 많은 미세한 모우가 발생되었으며 천연섬유에 버금가는 외관과 촉감이 발현되었다.As shown in FIG. 1, the manufactured composite yarn produced a myriad of fine wool on the surface of the yarn, and the appearance and feel comparable to that of natural fibers were expressed.

본 발명은 심사의 주면에 극세섬유웹이 피복되어서 표면에 다수의 미세한 모우가 형성되므로 천연섬유에 가까운 촉감을 나타낼 뿐만아니라 종래의 방법에 비하여 매우 간단한 공정으로 제조할 수 있으므로 복합사의 생산원가를 절감시킬 수 있다.In the present invention, since the fine fiber web is coated on the main surface of the screen, a large number of fine wool is formed on the surface, which not only shows a close touch to natural fibers but also can be manufactured by a very simple process compared to the conventional method, thereby reducing the production cost of the composite yarn. You can.
