파일직물의 제조방법Manufacturing method of pile fabric

본 발명은 간단한 제조공정에 의하여 길이가 다른 파일(pile)로 구성되는 파일직물의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a pile fabric composed of piles of different lengths by a simple manufacturing process.

지금까지 인조모피제조시에 탄력성을 향상시키기 위하여 파일의 길이가 다른 파일직물을 제조하여 왔다.Until now, pile fabrics having different lengths of piles have been manufactured to improve elasticity in the manufacture of artificial fur.

파일의 길이를 다르게 하는 방법으로는 첫째 파일을 터프팅(tufting)한 후 파일의 길이가 다르도록 절단하는 방법, 둘째 수축율이 다른 2종의 개질폴리에스터사를 사용하여 후처리시에 열수축율차이를 일으켜서 파일길이가 상이하게 하는 방법등이 알려져 있다.In order to change the length of the pile, the first pile is tufted, and the pile is cut to have a different length, and the second shrinkage ratio is different during post-treatment using two modified polyester yarns having different shrinkage rates. It is known to cause different file lengths by causing.

상기 방법중 첫째 방법은 절단할때 파일의 길이가 다르도록 절단하여야 하므로 공정관리면에서 어려움이 있으며, 둘째의 방법은 개질된 섬유와 보통섬유간의 물성차이를 초래할 뿐만 아니라 개질섬유의 물성이 저하되는 문제점이 있다.The first method of the above method has difficulty in process management because the length of the file must be cut when cutting, and the second method not only causes the difference of physical properties between the modified fiber and the ordinary fiber, but also decreases the physical properties of the modified fiber. There is a problem.

본 발명자는 상술한 바와 같은 종래 기술의 문제점을 해결한 것으로서 간단한 공정만으로도 파일의 길이가 상이한 파일직물을 제조하는 방법을 제공하는데 목적이 있는 것이다.The present inventors have solved the problems of the prior art as described above, and an object of the present invention is to provide a method for manufacturing pile fabrics having different lengths of piles with a simple process.

이하 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 비수수축율(100℃ 열수×15분)차이가 4∼10%인 2종 이상의 원사를 사용하여 파일직물을 제조한 다음 열처리온도가 상이한 2개 이상의 욕조(bath)에서 열수축시켜 제조함을 특징으로 하는 파일직물의 제조방법이다.The present invention is to produce a pile fabric using two or more kinds of yarns having a non-shrinkage rate (100 ℃ hot water × 15 minutes) difference of 4 to 10% and then heat shrink in two or more baths having different heat treatment temperatures. It is a manufacturing method of pile fabric characterized by the above-mentioned.

본 발명에서 다단의 파일층을 제조하기 위한 기본원리로서 파일사로서 사용되는 섬유의 결정화도를 달리하므로서 열수축율을 다르게 하여 후공정인 열욕조에서 열수축시키므로 다단층의 파일직물을 제조하는 것이다.In the present invention, by varying the degree of crystallinity of the fiber used as the pile yarn as a basic principle for manufacturing the pile layer in the multi-layer, the heat shrinkage is changed to heat shrink in a heat bath that is a post-process to produce a pile fabric of multi-layer.

본 발명에서 비수수축율차이가 다른 원사는 섬유제조시에 섬유의 결정화도가 달라지게 하여 제조할 수 있다.Yarns having different non-shrinkage difference in the present invention can be produced by varying the degree of crystallinity of the fiber during fabrication.

파일의 길이가 3단으로 되어 있는 파일직물에 사용되는 파일사의 제조방법을 예시하면 아래와 같다.An example of the manufacturing method of the pile yarn used for the pile fabric having a length of the pile is as follows.

장층 : 고유점도 0.65인 폴리에틸렌테레프탈레이트를 방사속도 2,000m/분으로 방사한 후 냉각온도 25∼45℃로 냉각하고 연속해서 연신배율 4.0∼4.5배로 연신하면 결정화도가 55∼70%인 폴리에스터섬유가 얻어짐.Long layer: Polyethylene terephthalate with an intrinsic viscosity of 0.65 is spun at a spinning speed of 2,000 m / min, then cooled to a cooling temperature of 25 to 45 ° C, and stretched at a stretching ratio of 4.0 to 4.5 times, resulting in a polyester fiber having a crystallinity of 55 to 70%. Obtained.

중층 : 고유점도 0.65인 폴리에틸렌테레프탈레이트를 방사속도 2,000m/분으로 방사한 후 냉각온도 10∼15℃로 냉각하고 연속해서 연신배율 3.2∼3.6배로 연신하면 결정화도가 30∼40%인 폴리에스터섬유가 얻어짐.Middle layer: After spinning polyethylene terephthalate with an intrinsic viscosity of 0.65 at a spinning speed of 2,000 m / min, cooling it at a cooling temperature of 10 to 15 ° C and stretching it continuously at a stretching ratio of 3.2 to 3.6 times, a polyester fiber with a crystallinity of 30 to 40% is obtained. Obtained.

단층 : 고유점도 0.65인 폴리에틸렌테레프탈레이트를 방사속도 2,000m/분으로 방사한 후 냉각온도 -10∼5℃로 급냉시키고 연속해서 연신배율 2.0∼2.5배로 연신하면 결정화도가 15∼25%인 폴리에스터섬유가 얻어짐.Monolayer: Polyester fiber with a crystallinity of 15 to 25% by spinning polyethylene terephthalate with an intrinsic viscosity of 0.65 at a spinning speed of 2,000 m / min, quenching to a cooling temperature of -10 to 5 ° C, and stretching at a stretching ratio of 2.0 to 2.5 times. Is obtained.

이와 같이 제조한 3가지 섬유의 비등수수축율(100℃×15분)은 장층섬유가 3∼6%, 중층섬유가 10∼13%, 단층섬유가 15∼20%로 그 수축율이 상이하게 된다.The boiling shrinkage (100 占 폚 x 15 minutes) of the three fibers prepared in this way differs in shrinkage rate from 3 to 6% for the long layer fiber, 10 to 13% for the middle layer fiber, and 15 to 20% for the single layer fiber.

상기한 바와 같은 3종의 섬유를 사용하여 파일직물을 제조한 후 열처리온도가 상이한 2개이상의 150℃∼210℃의 욕조에서 열처리하면 수축율이 다른 3종의 섬유가 3단계의 수축을 일으켜서 3단 파일직물이 된다.After the pile fabric is manufactured using the three kinds of fibers as described above, when the heat treatment is performed in two or more baths of 150 ° C. to 210 ° C. having different heat treatment temperatures, three types of fibers having different shrinkage ratios cause three steps of shrinkage. It becomes a pile fabric.

본 발명에 사용되는 2종 이상의 원사간의 비수수축율의 차이는 4∼10%가 적당하다.As for the difference in the non-shrinkage rate between 2 or more types of yarns used for this invention, 4-10% is suitable.

만일, 4% 미만일 경우 충분한 수축율의 차이를 줄 수 없기 때문에 탄력성이 풍부한 파일직물을 제조하기 어려우며, 10%를 초과하는 경우 충분한 탄력성을 유지하면서 3층 이상의 파일층을 형성시키기 어렵다.If it is less than 4%, it is difficult to produce a resilient pile fabric because it can not give a sufficient difference in shrinkage rate, if it exceeds 10% it is difficult to form a pile layer of three or more layers while maintaining sufficient elasticity.

또 본 발명에 사용되는 욕조의 온도는 제 1욕조를 150℃로 하고 제 2욕조를 190℃, 제 3욕조를 208℃로하는 것이 좋으며 각각의 온도에 의한 수축율차이를 갖는 원사에 의하여 3층 파일직물을 제조할 수 있게 된다.In addition, it is preferable that the temperature of the bath used in the present invention be 150 ° C. for the first bath, 190 ° C. for the second bath, and 208 ° C. for the third bath. It becomes possible to manufacture the fabric.

본 발명은 종래처럼 개질폴리에스터섬유를 사용하지 않으므로 물성저하를 방지할 수 있으며 다단계 열수축만으로 파일의 길이가 다르게 제조할 수 있으므로 제조공정이 매우 간단하다.Since the present invention does not use modified polyester fibers as in the prior art, it is possible to prevent a decrease in physical properties and the manufacturing process is very simple because the length of the pile can be differently produced only by multi-stage heat shrinkage.
