Abstract

In the method, melt-spun thermoplastic synthetic filaments pass through an air jet unit (2) to be subject to air jets released at 3- 10kg/cm2 in the direction of drawing the element, proceed through between two electrostatic units (3) to bring further fabrillation, pass through hot air jet stream released at 8-10kg/cm2 and 150-250 deg. C at the hot air jet unit (4) to produce loops and crimps, which are cooled in contact with the outer surface of a cooling drum to be spun into yarn. Pref. the stretchability of the filament is 5±3 denier and the drawing speed being 800-4000m/min.

본 발명은 폴리에스테르나 폴리아미드와 같이 용융방사한 열가소성 합섬필라멘트사를 사용하여 연속공정으로 벌키성이 풍부한 스펀라이크사를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a bulky spun-like yarn in a continuous process using thermoplastic spun filament yarn melt-spun such as polyester or polyamide.

종래에는 용융방사한 열가소성 합섬필라멘트사를 일단 UDY 및 POY 상태로 권취한 다음 별도의 연신기에서 연신하여서 연신사를 제조한 후 다시 이것을 텍스튜어링기(Texturieng m/c)에서 벌키가공을 하여 스펀라이크사를 제조하는 것이 일반적이다.Conventionally, the molten spun thermoplastic synthetic filament yarn is wound up once in UDY and POY state and then stretched in a separate stretching machine to prepare a stretched yarn, which is then spun-like by bulking in a texturing machine (Texturieng m / c). It is common to manufacture yarns.

그러므로 종래의 방법은 많은 단계를 거쳐야 했기 때문에 공정이 복잡하고 많은Therefore, because the conventional method had to go through many steps, the process was complicated and

본 발명은 공지된 단일의 연속공정에 의하여 용융방사된 합섬필라멘트사를 연신→개섬→벌키화함으로서 벌키성이 풍부한 스펀라이크사를 제조함에 있어서, 다음과 같이 제조함을 특징으로 하는 것인바, 이하 예시도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to produce a spun-like yarn rich in bulkiness by stretching → opening island → bulking the melt spun filament yarn melted by a single known continuous process, characterized in that the manufacturing as follows: When described in detail by way of example drawings as follows.

공기노즐(2)은 3㎏/㎠-10㎏/㎠의 압력을 갖는 압축공기가 측면에서 투입되어 필라멘트사(Y)의 진행방향으로 불어주도록 되어있어서 필라멘트사(Y)는 공기노즐(2)을 통과하면서 연신된다. 정전기 부하장치(3)는 양측에 정전기를 부하시켜서 그 사이를 통과하는 필라멘트사(Y)를 양쪽으로 당김으로써 필라멘트사가 개섬되도록 한다.The air nozzle 2 is configured to blow compressed air having a pressure of 3 kg / cm 2 -10 kg / cm 2 from the side and blow in the advancing direction of the filament yarn Y so that the filament yarn Y is the air nozzle 2. Stretched while passing through. The electrostatic load device 3 loads static electricity on both sides and pulls the filament yarns Y passing through them to both sides so that the filament yarns are opened.

과열공기분사장치(4)는 압력 8㎏/㎠-10㎏/㎠, 온도 150℃-250℃의 과열압축공기가 투입되며 여기를 지나면서 필라멘트사는 가열압축공기에 의하여서 루우프와 크림프가 발생된다.The superheated air injector 4 is supplied with superheated compressed air at a pressure of 8 kg / cm 2 -10 kg / cm 2 and a temperature of 150 ° C.-250 ° C., where the filament yarn is generated by loops and crimps by heated compressed air. .

냉각드럼(5)는 주면으로부터 내부도 냉각공기가 흡입되도록 되었으며 주면과 접촉하면서 통과하는 필라멘트사를 냉각시켜서 가열공기분사장치(4)에서 발생시킨 루우프와 크림프를 고정시킨다.Cooling drum (5) is to allow the cooling air to be sucked from the main surface inside to cool the filament yarn passing through the main surface to fix the loops and crimps generated by the heating air injection device (4).

본 발명에 사용되는 멀티필라멘트사의 단사섬도 5±3데니어의 범위가 좋으면 최종연신속도는 800-4,000m/분이고 과급율은 5-30%로 하였다.If the single filament fineness of the multifilament yarn used in the present invention is in the range of 5 ± 3 denier, the final drawing speed is 800-4,000 m / min and the supercharging rate is 5-30%.

본 발명은 연신된 필라멘트사를 먼저 개섬(開纖)한 다음 과열공기로 루우프와 크In the present invention, the drawn filament yarn is first opened and then looped and crocheted with superheated air.
