Description

형태안정성이 우수한 더블커버링사의 제조방법{Process Of Producing Double Covering Yarn Having Good Shape Stability}Manufacturing method of double covering company with excellent shape stability{Process Of Producing Double Covering Yarn Having Good Shape Stability}

본 발명은 형태안정성이 우수한 더블커버링사의 제조방법에 관한 것으로서 사제조후 열처리에 의해 신축성이 없고 촉감이 딱딱하여 형태안정성이 우수한 더블커버링사를 제조하는 것이다.The present invention relates to a method for manufacturing a double-covering yarn having excellent shape stability, and to manufacture a double-covering yarn having excellent shape stability due to its inflexibility and hard feel by heat treatment after manufacture.

최근 소득수준의 향상과 함께 의류에 다양한 기능성을 중시하는 수요 및 관심이 증가됨에 따라 다기능성을 가지는 섬유제품이 다양하게 개발되고 있다. In recent years, along with the increase in income level, as demands and interests that focus on various functionalities in clothing have increased, various textile products having multifunctionality have been developed.

특히, 가방과 같은 물품에 사용되는 편직물의 경우 신축성이 없어야 무게가 있는 물건을 담는 경우에 형태가 안정될 수 있고, 신발의 경우에는 형태가 안정적으로 고정이 되어야 한다. In particular, in the case of a knitted fabric used for an article such as a bag, there should be no elasticity so that the shape can be stabilized when carrying a heavy object, and in the case of a shoe, the shape should be fixed stably.

그러나 종래의 편직물의 경우에는 신축성이 있어서 무게가 있는 물건을 담는 제품이나 형태가 안정적으로 고정이 되는 제품을 만드는 데에 제약이 많은 문제점이 있었다.However, in the case of the conventional knitted fabric, there is a problem in that there are many limitations in making a product containing a heavy object or a product in which the form is stably fixed because it is elastic.

대한민국실용신안등록제20-0348046호(2004년04월28일 공고)Korea Utility Model Registration No. 20-0348046 (announced on April 28, 2004)

그러므로 본 발명에서는 제품의 컬러나 질감에는 영향을 덜 미치면서도 열셋팅을 통해 수축이 되어 원단을 두껍고 신축성이 없도록 작용을 하여 늘어짐을 지양하는 편물 제품을 제공할 수 있는 형태안정성이 우수한 더블커버링사를 제공하는 것을 기술적과제로 한다. Therefore, in the present invention, a double covering yarn having excellent shape stability that can provide a knitted product that avoids sagging by acting so that the fabric shrinks through heat setting and has less elasticity while having less influence on the color or texture of the product is provided. Provided is a technical task.

그러므로 본 발명에 의하면, 커버링사의 제조방법에 있어서,Therefore, according to the present invention, in the manufacturing method of the covering company,

코어사인 스판덱스사에 원착폴리에스테르DTY사를 제1커버링사로 커버링한 후, 나일론필라멘트사를 제2커버링사로 커버링하되 제1커버링사의 반대방향으로 커버링한 후 120~180℃, 5~60초 간 열셋팅하는 것을 특징으로 하는 형태안정성이 우수한 더블커버링사의 제조방법이 제공된다.After the core polyester spandex yarn is covered with the original polyester DTY yarn with the first covering yarn, the nylon filament yarn is covered with the second covering yarn but covered in the opposite direction of the first covering yarn, and then heated at 120 to 180°C for 5 to 60 seconds. A method of manufacturing a double-covering yarn having excellent shape stability characterized by setting is provided.

이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명은 형태안정성이 우수한 더블커버링사의 제조방법에 관한 것으로서 사제조 후 열처리에 의해 촉감은 부드러우면서도 신축성이 없이 형태안정성이 우수한 더블커버링사를 제조하는 것이다. The present invention relates to a method for manufacturing a double-covering yarn having excellent shape stability, and to manufacture a double-covering yarn having excellent shape stability without elasticity and soft feel by heat treatment after manufacture.

본 발명의 더블커버링사의 제조방법은 먼저, 코어사인 스판덱스사에 원착폴리에스테르DTY사를 제1커버링사로 커버링한다. The manufacturing method of the double-covering yarn of the present invention, first, covers the original polyester DTY yarn with the core-sine spandex yarn with the first covering yarn.

상기 코어사는 폴리우레탄사를 사용하여 해당 조건의 열을 가했을 때 원사가 수축, 경화되면서 편직물의 신축성을 없애는 역할을 하도록 하는 것이다. 상기 코어사에 원착폴리에스테르DTY사를 제1커버링사로 커버링하게 되는데, 상기 제1커버링사는 TM 600~800으로 커버링하는 것이 벌키한 질감 표현에 바람직하한데, TM 600미만에서는 벌키함이 과다하게 생기게 되며, TM 800초과시에는 치밀함이 과다하게 된다.The core yarn is used to remove the elasticity of the knitted fabric as the yarn shrinks and hardens when heat of the corresponding conditions is applied using the polyurethane yarn. The original polyester DTY yarn is covered with the first covering yarn on the core yarn, and the first covering yarn is preferable for expressing bulky texture with TM 600-800, but less than TM 600 causes excessive bulkiness. When the TM exceeds 800, the density becomes excessive.

상기 원착폴리에스테르DTY사는 50~150d/48fila인 원착폴리에스테르필라멘트를 제1피드롤러로 공급하고 190~210℃의 제1히터를 통과시킨후 벨트타입가연기로 가연비 1.45~1.60으로 가연한 후 연신비 1.70~1.90으로 제2피드롤러를 통과시키고, 인터레이스노즐로 인터레이스한 후 제3피드롤러를 통과시켜 사속 600~750m/분으로 권취하여 제조된 것을 사용하는 것이 열처리 했을 때 원사끼리 엉겨 붙음을 방지에 바람직하다. The original polyester DTY company supplies the original polyester filament of 50 to 150 d/48fila to the first feed roller, passes the first heater at 190 to 210°C, and then combusts with a belt type combustor at a fuel consumption ratio of 1.45 to 1.60, and then draws. It is used to pass the second feed roller from 1.70 to 1.90, interlace with an interlaced nozzle, and then pass through the third feed roller to wind at a speed of 600 to 750 m/min to prevent the yarns from sticking together when heat treated. desirable.

상기 제1커버링후에는 나일론필라멘트사를 제2커버링사로 커버링하되 제1커버링사의 반대방향으로 커버링하여 원사 길이의 안정성을 확보하게 된다. 연의 방향이 동일할 경우 최종 커버링후 해사되면서 커버링 방향으로 원사가 회전하면서 원사길이가 줄어들기 때문이다. After the first covering, the nylon filament yarn is covered with the second covering yarn but covered in the opposite direction of the first covering yarn to secure the stability of the yarn length. This is because when the direction of the kite is the same, the yarn length decreases as the yarn rotates in the covering direction as it is released after the final covering.

상기 제2커버링사는 TM 900~1500으로 커버링하는 것이 벌키한 질감 표현에 바람직한데, TM 900미만에서는 커버링 루프 형상이 약해지며, TM 1500초과시에는 볼륨감이 과다해진다.Covering the second covering yarn with TM 900 to 1500 is preferable for expressing a bulky texture, but under TM 900, the covering loop shape is weakened, and when TM 1500 is exceeded, a sense of volume is excessive.

상기 스판덱스사는 100~120d/6~14fila이고, 원착폴리에스테르DTY사는 150~160d/48fila이고, 나일론필라멘트사는 100~130d/12~34fila인 것을 사용하는 것이 바람직하다.The spandex yarn is 100 to 120d/6 to 14fila, the original polyester DTY yarn is 150 to 160d/48fila, and the nylon filament yarn is preferably 100 to 130d/12 to 34fila.

이렇게 제1차커버링 및 제2차커버링을 한 후 120~180℃, 5~60초간 열셋팅하여 스판덱스가 녹았을 때 신축성이 없도록 하여 본 발명의 형태안정성이 우수한 더블커버링사를 제공하게 된다.Thus, after the first and second coverings are heat-set for 120 to 180° C. for 5 to 60 seconds to prevent stretching when the spandex is melted, a double covering yarn having excellent shape stability of the present invention is provided.

열셋팅 과정에서 스판덱스가 녹고 커버링된 원착 폴리에스테르DTY사와 나일론필라멘트사가 쪼그라들어 원단이 수축되고 두꺼워지게 되어 내구성이 높아진다. During the heat setting process, the spandex melts and the covered original polyester DTY and nylon filament yarns crush and the fabric shrinks and thickens, increasing durability.

그러므로 본 발명의 더블커버링사는 열셋팅을 통해 수축이 되어 원단을 두껍고 신축성이 없도록 작용을 하여 늘어짐을 지양하는 가방, 신발 및 인테리어소품용 편직 원단 제품에 적용하는 것에 그 용도가 적합하다. Therefore, the double-covering yarn of the present invention is suitable for application to a knitted fabric product for bags, shoes, and interior items that avoids sagging by shrinking through heat setting and acting so that the fabric is thick and not stretchable.
