Description
본 발명은 흡한·속건성이 우수한 폴리에스터 섬유의 제조방법에 관한 것으로, 특히 섬유의 횡단면 방향으로 다수의 돌출부를 형성시켜 수분의 이동통로를 형성한 폴리에스터 이형단면섬유의 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing polyester fibers having excellent sweat absorption and quick drying, and more particularly, to a method for producing polyester cross-section fibers in which a plurality of protrusions are formed in the cross-sectional direction of the fiber to form a moving passage of moisture.
폴리에스터섬유는 고배향(高配向), 고결정(高結晶) 특성을 갖기 때문에 의류와 산업자재용등 폭 넓게 이용되어 왔으나, 유연성과 흡습성이 약간 떨어지는 결점이 있어, 천연섬유와 같은 부드러운 촉감을 가질 수 없으며, 땀을 잘 흡수하지 못하는 결함이 문제가 되어 왔다.Polyester fibers have been widely used in clothing and industrial materials because they have high orientation and high crystallinity. However, they have a weakness in softness and hygroscopicity, which makes them feel soft like natural fibers. It has been a problem that can not have, a defect that does not absorb sweat well.
따라서 폴리에스터 섬유에 각종 기능성을 부여하여, 고급 의류용 소재로서 개질코자 하는 연구가 활발하게 진행되어 왔으며, 특히 스포츠웨어용 소재로 사용하는 경우, 몸에서 발산되는 땀을 신속히 흡수하여 짧은 시간에 건조시킬 수 있도록 함으로써, 착용시 쾌적성을 극대화할 수 있는 기능이 요구되어 왔다.Therefore, research has been actively conducted to impart various functionalities to polyester fiber and to modify it as a material for high-end clothing. Especially, when used as a material for sportswear, it quickly absorbs sweat emitted from the body and dries it in a short time. By making it possible, a function that can maximize the comfort when worn has been required.
종래에 인조섬유에 대한 흡한·속건성의 개질을 위하여, 칩 제조시 친수성 폴리머를 사용하는 화학적 방법과, 섬유간의 공극을 많이 발생하도록 하기 위해 섬유의 단면을 변화시키는 물리적 방법이 제안되어 왔다. 우리나라 공개특허번호 제91-6999호에 U자형의 이형단면을 갖는 폴리에스터사의 제조방법이 제안되고 있으나, 수분의 이동통로가 한곳으로 제한되어 있어서 흡습능력이 떨어지는 단점이 있었다.Background Art Conventionally, in order to modify sweat absorption and quick drying to artificial fibers, a chemical method using a hydrophilic polymer during chip production and a physical method of changing the cross section of the fiber in order to generate a lot of voids between the fibers have been proposed. In Korea Patent Publication No. 91-6999, a method for producing a polyester yarn having a U-shaped cross section has been proposed, but has a disadvantage in that the moisture absorption ability is limited because the movement path of moisture is limited to one place.
본 발명은 상기한 문제점을 해결하기 위하여, 폴리에스터 섬유의 표면에 길이방향으로 다수의 요철 돌출부를 형성하여 섬유상호간의 공극부를 크게 하고, 모세관 현상에 의한 수분의 이동통로를 부여하여 땀의 이동속도를 빠르게 하므로써흡한성능을 개선시키고, 섬유단면의 요철부에 의하여 피부와 닿는 접촉면을 최소화 하므로써 쾌적한 느낌을 느낄 수 있도록 하는 것을 그 목적으로 한다.In order to solve the above problems, the present invention provides a plurality of uneven protrusions in the longitudinal direction on the surface of the polyester fiber to increase the voids between the fibers, and provides a movement path of the sweat by capillary action to move the sweat. Its purpose is to improve the absorbed performance by speeding up and to feel comfortable by minimizing the contact surface in contact with the skin by the uneven portion of the fiber cross section.

본 발명자들은 상기한 과제에 대해서 충분히 검토한 결과, 폴리에스터 섬유의 표면에 적어도 6개 이상의 돌출부로 구성된 수분이동 통로를 가지도록 함으로써 상기 과제를 해결할 수 있게 되었다. 이하 본 발명의 흡한 속건성 폴리에스터 섬유의 제조방법에 대하여 구체적으로 설명한다.MEANS TO SOLVE THE PROBLEM As a result of full examination of the said subject, the present subject became able to solve the said subject by having the water movement path | route which consists of at least 6 protrusions on the surface of polyester fiber. Hereinafter, the manufacturing method of the sweat-absorbing quick-drying polyester fiber of this invention is demonstrated concretely.
도1과 같은 편평 슬릿트의 좌, 우측 양측에 2개씩의 원형 돌출부를 가지며, 원사 제조시 도 2와 같은 6개의 수분이동 통로를 가지는 본 발명 흡한 속건성 폴리에스터 제조를 위하여,For manufacturing the present invention quick-drying polyester having two circular protrusions on each of the left and right sides of the flat slit as shown in FIG. 1 and having six water movement passages as shown in FIG.
구형 돌출부의 직경(c)에 대한 편평 슬릿트의 길이(b) 의 비율을 "A"라고 할 때, 하기 식(1)에서와 같이 A의 값이 4.0 ≤ A ≤ 5.7 가 되도록 한다, 바람직하기는 4.4≤ A ≤ 5.0 범위가 좋으나, 이 경우 A 의 값이 4.0 이하가 되면, 돌출부의 크기가 커져서 수분이동통로의 형성에는 유리하나, 방사시 사절등의 발생으로 작업성이 불리하게 되며, 또한 A 의 값이 5.7 이상이 되면, 돌출부의 크기가 작아져 흡수성이 떨어지고, 방사시 배면압의 상승으로 팩압이 급상승하는 문제가 발생하여 조업에 문제가 발생하게 된다.When the ratio of the length b of the flat slit to the diameter c of the spherical protrusion is " A ", the value of A is set to 4.0 < = A < The range of 4.4≤A≤5.0 is good, but in this case, when the value of A is 4.0 or less, the size of the protrusion is increased, which is advantageous for the formation of the water passage, but the workability is disadvantageous due to the generation of trimming during spinning. If the value of A is greater than or equal to 5.7, the size of the protruding portion becomes smaller and the absorbency decreases, and the pack pressure rises rapidly due to the increase of the back pressure during spinning, which causes problems in operation.
4.0 ≤ A ≤ 5.7 ...................... 식 (1)4.0 ≤ A ≤ 5.7 ... (1)
또한 두개의 원형 돌출부의 간격(d)은 0.2 mm 이상 0.6 mm 이하의 범위가되도록 한다. 원형 돌출부의 간격(d)이 0.2 mm 보다 작으면, 두개의 원형단면이 방사시 너무 접근하여 융착이 발생하므로 수분이동 통로의 형성이 불리하게 되며, 0.6 mm이상이 되면, 반 폐쇄형의 수분이동 통로의 형성을 이룰수 없어 흡수성이 떨어지는 폐단이 있다.In addition, the spacing d of the two circular protrusions is in the range of 0.2 mm or more and 0.6 mm or less. If the distance (d) of the circular protrusion is smaller than 0.2 mm, the two circular cross-sections are too close to the spinning and fusion occurs, so that the formation of the water passage is disadvantageous. There is a closed end that is unable to form passages and thus has low absorbency.
또 편평 슬릿트의 세로 길이에 대한 가로 길이의 비율(R)은 하기 식(2)을 만족하는 방사구금을 사용한다.In addition, the ratio (R) of the horizontal length to the vertical length of the flat slit uses a spinneret satisfying the following expression (2).
10 ≤ R ≤ 15 ..................... 식 (2)10 ≤ R ≤ 15 ..................... Equation (2)
이하, 실시예에 의하여 본 발명을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.

종래의 폴리에스터섬유는 천연섬유에 비해 흡습성이 저하되어 동절기에는 정전기 발생이 심하고, 하절기에는 땀이나 수분의 흡수능력이 적어 고급 의류용으로 부적합한 단점이 있었으나, 본 발명에 의하면, 섬유 표면부에 형성된 수분이동 통로에 의해 몸에서 발생한 땀은 빠르게 흡수하며, 흡수된 땀은 섬유 내부에까지 침투하지 않고, 표면부에 있게되므로 통풍에 의해 빨리 건조되는 효과를 가지게 된다.Conventional polyester fiber has a disadvantage in that the hygroscopicity is lower than that of natural fiber, the generation of static electricity in the winter season, the sweat and moisture absorption in the summer season is less suitable for high-end clothing, but according to the present invention, The sweat generated in the body by the moisture movement path is quickly absorbed, and the absorbed sweat does not penetrate into the inside of the fiber, and thus remains on the surface, thereby having an effect of drying quickly by ventilation.
