Abstract

본 발명은 중공이형단면섬유에 관한 것이다.The present invention relates to a hollow release cross section fiber.

종래에는 단순한 원형단면의 중공섬유이거나 중공이 아닌 이형단면섬유만이 알려져 있을 뿐이었다.Conventionally, only circular cross-section hollow fibers or only non-hollow cross-section fibers are known.

본 발명은 중공율이 5∼15%이고, 이형율이 10∼30%인 중공이형섬유이다.The present invention is a hollow release fiber having a hollow ratio of 5 to 15% and a release rate of 10 to 30%.

본 발명의 중공이형섬유는 흡수율이 40% 이상으로 우수함과 동시에 탄성회복율도 우수하므로 각종 페인트 브러쉬나 화필용 브러쉬의 원사로 활용된다.Hollow release fiber of the present invention is excellent in the absorption rate of 40% or more, and also excellent in the elastic recovery rate is utilized as a yarn of various paint brushes or paint brushes.

[발명의 명칭][Name of invention]

이형중공섬유Release Hollow Fiber

[발명의 상세한 설명]Detailed description of the invention

[발명의 목적][Purpose of invention]

[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical field to which the invention belongs and the prior art in that field]

본 발명은 페인트 브러쉬 혹은 화필용 브러쉬에 적합한 이형중공(異形中空)섬유에 관한 것으로서, 특히 탄성회복율과 흡수율이 함께 우수한 열가소성 합성섬유의 이형중공섬유에 관한 것이다.The present invention relates to a release hollow fiber suitable for a paint brush or a brush for brush, and more particularly to a release hollow fiber of thermoplastic synthetic fiber having excellent elastic recovery rate and water absorption rate.

종래에도 이형단면섬유가 알려진 바 있으나 중공부를 가진 이형단면섬유는 알려진 바 없으며, 또 중공섬유로서 그 단명형태가 이형인 섬유도 알려진바 없다.In the related art, there is no known sectional cross-section fiber, but no sectional cross-section fiber having a hollow part is known, and no fiber having a short-lived shape as a hollow fiber is known.

즉 종래에는 이형단면섬유는 흡수율이 부족하고 원형중공섬유는 탄성회복율이 불량하였었기 때문에 우수한 흡수율과 탄성회복율이 동시에 요구되는 페인트 브러쉬나 화필용 브러쉬의 원사로 사용하기에는 적합하기 못한 문제점이 있었다.In other words, conventional cross-sectional fiber has a problem in that it is not suitable for use as a yarn for paint brushes or paintbrushes that require both excellent absorption and elastic recovery rate because the absorptive fiber lacks the absorptivity and the circular hollow fiber has a poor elastic recovery rate.

[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]

본 발명은 흡수율과 탄성회복율이 동시에 우수하여서 페인트 브러쉬나 화필용 브러쉬의 원사로 사용하기에 적합한 이형중공섬유를 제공하는데 그 목적이 있는 바 이하 상세히 설명하면 아래와 같다.The present invention is to provide a release hollow fiber suitable for use as a yarn of a paint brush or a brush for the excellent absorption and elastic recovery at the same time bar as described in detail below.

본 발명은 다음 조건을 전부 만족시키는 이형중공섬유이다.The present invention is a release hollow fiber that satisfies all of the following conditions.

다 음next

5 ≤ 중공율(%) ＜ 155 ≤ hollowness (%) <15

10 ≤ 이형율(%) ＜ 3010 ≤% Release <30

본 발명에서 중공율이 5% 미만이면 수분흡수율이 불량하고 15%를 초과하면 제조하는데 어려움이 있다.In the present invention, if the hollow ratio is less than 5%, water absorption is poor, and if it exceeds 15%, it is difficult to manufacture.

또 본 발명에서 이형율이 10% 미만이면 탄성회복율이 높지 못하고 30%를 초과하면 방사구금을 준비하고 사를 제조하는데 또한 어려움이 크며 내마모성이 약하다.In addition, when the release rate is less than 10% in the present invention, the elastic recovery rate is not high, and when the release rate is more than 30%, it is also difficult to prepare a spinneret and manufacture a yarn, and the wear resistance is weak.

본 발명의 이형중공섬유는 수분흡수율이 40% 이상이며 탄성회복율이 우수하다.The release hollow fiber of the present invention has a water absorption of 40% or more and excellent elastic recovery.

[실시예 및 비교예][Examples and Comparative Examples]

폴리에스테르 폴리머, 나일론 612 및 폴리부틸렌테레프탈레이트(PBT)를 중공이형단면의 방사구금으로 용융방사하여 중공이형단면사를 제조하였다.The polyester polymer, nylon 612 and polybutylene terephthalate (PBT) were melt spun into a spinneret of hollow release cross section to prepare a hollow release cross section yarn.

그 결과는 표 1과 같다.The results are shown in Table 1.

[발명의 효과][Effects of the Invention]

본 발명에 의한 이형중공섬유는 수분흡수율이 40% 이상으로 우수함과 동시에 탄성회복율도 우수하므로 각종 페인트 브러쉬나 화필용 브러쉬의 원사로 사용하기에 매우 적합한 장점이 있다.The release hollow fiber according to the present invention has an excellent water absorption rate of 40% or more and at the same time excellent elastic recovery rate, so it is very suitable for use as a yarn for various paint brushes or paint brushes.
