Description
본 발명은 보온성과 경량성이 우수한 폴리에스터 복합사 및 그 제조방법에 관한 것으로, 보다 자세하게는, 단사섬도 1.0데니어 미만의 중공단면과 원형단면의 원사를 각기 다른 사도를 거쳐 교락부에서 동시 교락하는 방법으로 폴리에스터 이형 복합사를 이용하여 보온성과 경량성이 우수하고 부드러운 촉감을 가지며 생산공정이 간단한 실크라이크 폴리에스터 복합사 및 그 제조방법에 관한 것이다.
The present invention relates to a polyester composite yarn having excellent heat retention and light weight, and a method of manufacturing the same, and more particularly, to simultaneously entangle hollow yarns having a single yarn fineness of less than 1.0 denier and yarns of circular cross section through different yarns at the same time. The present invention relates to a silk-like polyester composite yarn and a method of manufacturing the same, using polyester release composite yarns, having excellent heat retention, light weight, soft touch, and a simple production process.
종래에는 폴리에스터 섬유에 보온성과 경량을 부여하는 직물을 제조하기 위해서는 섬유의 단면형상을 중공형태로 만들어 원사 내부에 공기층을 형성하여 제조하는 방법이 제안되었으나, 경량성과 보온성은 부여할지라도 직물의 태가 뻣뻣하여 원사의 후가공 없이는 의류용으로 적용할 수 없으며, 다른 방법으로는 중공사의 딱딱한 촉감을 보완하기 위해 개질 칩을 혼방하여 중공 단면사를 제조하거나, 이종의 필라멘트사를 혼섬, 복합방사하여 제조한 후 제직하고 정련 및 염가공 하는 방법이 사용된다. 예를 들어, 대한민국 특허공개공보 제1996-0010919호에서는 황산바륨과 인화합물을 첨가한 개질 폴리머를 해성분으로 하여 도성분과 함께 복합방사하여 해도형태로 제사한 다음, 알칼리 감량처리에 의하여 해성분에 기공을 형성시켜 형성된 기공을 통하여 도성분을 용출시켜 중공사를 제조하는 방법이 제시되었으나, 복합방사는 제조공정 설비의 복잡성을 초래하고, 후가공을 제어해야 한다는 어려움이 있다. 또한, 대한민국 특허공개공보 제2000-0019270호에서는 단사섬도가 5∼7.5데니어로서 무기입자를 다량 함유한 폴리머를 사용한 원형중공단면사와 섬도가 1.0∼2.5데니어인 이종의 원사를 혼섬하여 가열장치인 열핀(Hot Pin)을 통과하면서 불균일 배향을 시켜 제조하는 방법을 제시하고 있으나, 상기 방법은 단사섬도가 높아 부드러운 촉감을 발현하기 힘들며, 또한 개질 칩 사용 및 2단계로 복합사를 생산하는 것으로 제조공정이 복잡하고 제조비용이 증가하는 문제점이 있다.
Conventionally, in order to manufacture a fabric that imparts insulation and light weight to polyester fibers, a method of manufacturing the fabric by forming an air layer inside the yarn by making the cross-sectional shape of the fiber hollow is proposed. It is stiff and cannot be applied to garments without the post-processing of yarn. Alternatively, it is possible to manufacture hollow cross-section yarns by blending modified chips in order to compensate for the firm touch of hollow yarns, or by blending and blending different filament yarns. Post weaving, refining and dyeing methods are used. For example, Korean Patent Publication No. 1996-0010919 discloses a modified polymer containing barium sulfate and phosphorus as a sea component, which is spun in a sea island form by complex spinning with island components, and then applied to the sea component by alkali weight loss treatment. Although a method of manufacturing hollow fiber by eluting the island component through pores formed by forming pores has been proposed, complex spinning causes difficulty in manufacturing process equipment and has a difficulty in controlling post processing. In addition, Korean Patent Laid-Open Publication No. 2000-0019270 has a single yarn fineness of 5 to 7.5 deniers, which blends circular hollow section yarns using polymers containing a large amount of inorganic particles with heterogeneous yarns having a fineness of 1.0 to 2.5 deniers. Although a method of manufacturing a non-uniform orientation while passing through a hot pin has been proposed, the method has a high single yarn fineness, which makes it difficult to express a soft touch, and also uses a modified chip and produces a composite yarn in two steps. There is a problem that this complexity and manufacturing cost increases.
따라서, 본 발명은 상기한 종래 기술에 있어서의 기술적 문제점을 감안하여 된 것으로, 본 발명의 주목적은 폴리에스터 복합사를 이용하여 공정이 간단하면서도 보온성과 경량성이 우수하며 부드러운 촉감을 가지는 폴리에스터 복합사를 제공하기 위한 것이다.Accordingly, the present invention has been made in view of the above technical problems in the prior art, and the main object of the present invention is a polyester composite yarn having a simple touch and excellent thermal insulation and light weight and having a soft touch.

As described above, according to a preferred embodiment of the present invention, the polyester composite yarn of the present invention spins the partial alignment yarn and the fully drawn yarn through separate detention in one spinning machine, and then interweaves at the focusing nozzle through a separate yarn. It is manufactured using a method for producing a composite yarn in one step, wherein the yarns constituting the composite yarn uses a circular cross-section partially oriented yarn and a hollow cross-section fully drawn yarn of less than 1.0 denier.
본 발명의 바람직한 실시형태에 따르면 단사 섬도 1.0데니어 미만의 원형 단면 부분배향사를 사용하는데 이는 중공사의 딱딱한 촉감을 개선하여 별도의 후가공 없이 부드러운 촉감을 발현할 수 있다.According to a preferred embodiment of the present invention, a circular cross-sectional partial orientation yarn having less than 1.0 denier of single yarn fineness is used, which improves the firm feel of the hollow yarns and thus expresses a soft touch without additional post processing.
