Description

에어제트방적 효과사Air Jet Spinning Effect Yarn
본 발명은 에어제트방적 효과사에 관한 것으로서, 보다 상세하게는 섬도가 다양하게 제어되는 에어제트방적 효과사에 관한 것이다.The present invention relates to an air jet spinning effect yarn, and more particularly, to an air jet spinning effect yarn in which fineness is controlled in various ways.
방적사를 제조하는 방식은 크게 링방적, 오픈엔드방적, 에어제트방적으로 대별될 수 있다. 링방적의 경우 원면을 개섬하고, 혼타면공정, 소면공정, 정소면공정, 연조공정, 조방공정, 정방공정을 거쳐 방적사를 제조한다. 한편 오픈엔드(Open End Spinng)의 경우 링방적에서 정소면, 조방, 정방공정을 1개의 공정으로 진행하고 에어제트방적은 공기 와류로 방적을 하는 방식으로 슬라이버에서 바로 방적사를 제조하는 방식이다. 에어제트방적은 드래프트된 섬유들이 공기 와류(air vortex)에 의하여 스핀들의 오리피스(orifice) 속으로 들어간다. 이 오리피스를 통과해 가는 동안에 소용돌이 치는 기류에 의해 꼬임을 받은 섬유들은 스핀들을 빠져나오며 실로 방출되어 나오게 된다.The method of manufacturing the yarn can be roughly divided into ring spinning, open end spinning, and air jet spinning. In the case of ring spinning, the yarn is opened, and the yarn is manufactured through a blending process, a carding process, a cotton processing process, a softening process, a spinning process, and a spinning process. On the other hand, in the case of open end spinng, the spinning yarn is made in one process from the spinning surface to the front surface, spinning and spinning processes in one step, and the air jet spinning is a method of manufacturing the yarn directly from the sliver by spinning with air vortex. Air jet spinning involves the drafted fibers entering the orifice of the spindle by an air vortex. As they pass through the orifice, the fibers twisted by the swirling airflow exit the spindle and are released into the thread.
에어제트방적은 연신한 섬유의 모우를 이용하여 섬유를 결속시키기 때문에 결속방이라고도 하고 볼텍스(Vortex)이라고도 한다. 또 에어제트방적은 실무에서는 MVS사로도 불리는데 에어제트방적용 기기를 제조하는 무라다사(社)의 설명의 약칭이다(Murata Vortex Spinning)Air jet spinning is also referred to as a binding room or vortex because it binds the fibers by using the wool of the stretched fiber. Airjet spinning is also called MVS in practice, and is an abbreviation for Murata Vortex Spinning, which manufactures air jet spinning equipment.
링정방의 경우 생산 속도는 낮지만, 링 방적사는 일반적으로 방적사 기술에서 가장 기본이 되는 구조로 인정받고 있다. 오픈엔드 정방에서는, 슬라이버 피드 스톡으로부터 섬유 다발이 오프닝 롤러와 기류에 의하여 개개 섬유들로 분리된다. 이렇게 분리된 섬유들은 로터 홈에서 재집속되고 도핑 튜브를 통과해 가면서 연속적인 형태의 실로 만들어지게 된다. 여러 가지 오픈엔드 타입의 정방 시스템이 개발되었지만, 아직까지 어느 방식도 로터 정방을 능가하여 성공한 것은 없다. 로터 정방에서는 딜리버리 속도가 200m/min까지 가능하지만, 일반적으로 100% 면사를 생산할 경우에 단지 Ne 30 정도까지 일반적으로 방출한다. 에어제트방적의 경우 100% 면사를 생산할 경우 좀더 폭 넓은 범위의 섬유장을 사용할 수 있어, 생산 가능한 실의 방출 번수도 다양해지게 되었다. 또 에어제트방적 시스템은 실의 딜리버리 속도가 500m/min 까지 가능하며 생산성이 우수한 특징이 있다.In the case of ring spinning, the production speed is low, but ring spinning yarn is generally recognized as the most basic structure for spinning yarn technology. In open-end squares, fiber bundles from the sliver feed stock are separated into individual fibers by an opening roller and airflow. The fibers are then condensed in the rotor grooves and passed through the doping tube to form a continuous thread. Various open-end spinning systems have been developed, but none of them have succeeded beyond the rotor spinning. Delivery speeds up to 200 m / min can be achieved in the rotor spinning, but generally only up to Ne 30 when 100% cotton yarn is produced. In the case of air jet spinning, the production of 100% cotton yarn allows the use of a wider range of fiber lengths, resulting in a greater variation in the number of releases of the yarn that can be produced. In addition, the air jet spinning system can deliver up to 500m / min of seal delivery speed and has excellent productivity.
한편 일반적인 슬럽사(slub yarn) 제조방법은 링 정방기의 롤러 속도를 증감하여 드래프트 비를 변경시킴으로써 실을 주기적으로 굵은 부분과 가는 부분으로 만드는 것이다.On the other hand, the general method of manufacturing a slub yarn (slub yarn) is to change the draft ratio by increasing or decreasing the roller speed of the ring spinning machine to make the yarn into thick and thin parts periodically.
이러한 슬럽사는 혁신정방인 에어제트방적 공정에서 제안된 바는 없고 다만 다음과 같은 기술들이 시도되었는데, 대한민국 공개특허 제1986-0003372호에서는 심사에 대한 효과사의 공급속도(또는 공급량)를 더 빨리하여(많이 하여) 이들을 합사한후 에어제트 분사장치로 처리하는 슬라브사의 제조방법에 있어서 미리 예정된 프로그램챠드에 따라서 프로그램 디바이스(Program device)와 연결된 정역회전식 정밀모우터(M)에 나착된 나선축과 이동식안내간의 하단나선부를 교합시키고 이 이동식안내간의 상부에 있는 가이드를 통하여 효과사를 심사보다 약간 고속으로 통과시키므로서 이 이동식안내간의 다양한 이동상태에 의하여 심사와 효과사가 에어제트노즐(Air Jet Nozzle)속에서 슬럽부와 합연부가 다양하게 교호형성된 1리피이트를 연속적으로 형성되도록 하는 슬럽사의 제조방법이 개시되었다.Such a slub has not been proposed in the innovative jet jet process, but the following techniques have been tried. However, in Korean Patent Publication No. 1986-0003372, the effector's supply rate (or supply amount) for the inspection is made faster ( Slavic company manufacturing method of slab and then processing them by air jet injector, and the spiral shaft and mobile guide attached to the forward and reverse precision motor (M) connected to the program device according to the predetermined program chart. By interlocking the lower helix of the liver and passing the effector slightly faster than the screening through the guide on the upper part of the movable guide, the screening and effector can be operated in the air jet nozzle by the various movement states between the movable guides. The slop portion and the joint portion are formed in succession to form one alternating variety It was disclosed seulreop's production method.
한편 대한민국 등록특허 제1453310호에서는 고신축 복합필라멘트사를 심사로 하고, 신축성이 없는 복합필라멘트사를 부사로 하여 일정한 속도로 상향이동하되, 열처리장치를 통하여 고신축 복합필라멘트사로 된 심사를 간헐적으로 열처리하여 열처리부와 비열처리부가 불규칙한 간격으로 형성되게 하고, 상기 열처리된 심사와 열처리하지 않은 부사를 합사한 다음, 에어젯트노즐이 형성된 교락장치를 통과하면서 일정한 간격으로 공기를 분사시켜 심사와 부사가 엉켜진 슬럽이 형성되게 한 후 저장력으로 권취하여 슬럽사를 제조하고, 상기 슬럽사를 경위사로 하여 저장력으로 직물을 제직하고, 상기 직물을 염색, 가공하여 경위사로 사용한 고신축성 슬럽사의 심사가 수축하면서 직물이 경위사 양방향으로 신축될 수 있게 함과 동시에, 경위사로 사용한 슬럽사의 슬럽이 불규칙적으로 형성되게 하는 기술이 제안되었다.On the other hand, Korean Patent No. 1453310 uses a high-strength composite filament yarn as a screening and a non-elastic composite filament yarn as a sub-advancing to move upward at a constant speed, but intermittently heat-treats the screening of a high-strength composite filament yarn through a heat treatment device. The heat treatment part and the non-heat treatment part are formed at irregular intervals, and the heat treatment screening and the non-heat treatment adverb are combined together, and then the air is jetted at regular intervals while passing through the interlocking device in which the air jet nozzle is formed to entangle the screening and adverb. After forming the sloping yarn, it is wound with a storage force to produce a slop yarn, the slop yarn is used as a warp yarn to weave the fabric, and the fabric is dyed and processed to be used as a warp yarn. This can be used as a theodolite while allowing it to be stretched in both directions The technology that allows seulreop's seulreop irregularly formed as proposed.
그러나 상기 기술들은 합사를 통해 슬럽사를 제조하는 점에서 에어제트방적에 의해 형성되는 사 제조와는 매우 큰 차이가 있다. 에어제트방적의 경우 링정방에 비해 15 내지 20배의 공정속도가 빠르기 때문에 이러한 빠른 사속에 따른 슬럽 형성 간격이 너무 길어져 상품성 떨어지는 문제가 해결되기 어렵다. 더욱이 속도제어를 통해 슬럽사를 제조하기 때문에 속도제어를 위한 별도의 설비 및 고속제어가 가능한 특수 장치가 별도로 구비되어야 하지만 이러한 장치나 방법이 제안된 바 없다.However, the above techniques are very different from the yarns produced by air jet spinning in that the slop yarn is manufactured through plywood. In the case of air jet spinning, 15 to 20 times faster process speed than ring spinning, so the slug formation interval is too long due to this fast yarn speed, it is difficult to solve the problem of falling commodity. Furthermore, since the slab yarn is manufactured through speed control, a separate device for speed control and a special device capable of high speed control must be separately provided, but such a device or method has not been proposed.

The system can be broadly divided into a draft region 100, a vortex forming region 200, and a winding region (not shown).
본 발명에 의한 효과사는 별도의 속도제어와는 다른 방식으로 드래프트영역 100을 제어함으로서 이루어질 수 있다. 구체적으로 상기 드래프트영역 100의 프론트롤러 110의 형상을 제어함으로서 이루어질 수 있다. 상기 프론트롤러는 슬라이버가 백, 미들롤러를 거쳐 프론트롤러 110으로 공급되는데, 도 2에 도시된 바와 같이 프론트롤러의 표현형상에 일정한 폭과 두께로 형성된 음푹 파인 소정의 빈공간 111을 형성하여 상기 슬라이버가 프론트롤러를 통과할 때, 빈공간 111 영역에서는 슬라이버가 프론트톱, 바텀롤러 사이에 작용을 받지 않으므로 드래프트 작용을 받지 않고 통과하게 된다. 그리고 상기 빈공간 111을 제외한 표면영역 113을 슬라이버가 지날 ??는 프론트톱 및 바텀롤러의 작용에 의해 드래프트가 된다. 따라서 권취영역에서 형성된 사는 표면영역 113을 통과한 부분에서는 소정의 섬도를 유지하지만 빈 공간 111을 통과한 부분은 상기 표면영역 113을 통과한 사에 비해 상대적으로 더 높은 섬도를 형성하게 된다. 이로서 하나의 연속된 사에 굵기의 변화가 있는 사가 형성될 수 있다.The effect yarn according to the present invention may be achieved by controlling the draft area 100 in a manner different from the separate speed control. Specifically, it may be achieved by controlling the shape of the front roller 110 of the draft region 100. The front roller is provided with a sliver through the back and middle rollers to the front roller 110. As shown in FIG. 2, a predetermined hollow space 111 formed with a predetermined width and thickness is formed in the expression shape of the front roller. When the sliver passes through the front roller, the sliver is not acted between the front top and the bottom roller in the empty space 111, and thus passes through the draft roller. The sliver passes through the surface area 113 except for the empty space 111 and becomes a draft by the action of the front top and the bottom roller. Therefore, the yarn formed in the winding region maintains a predetermined fineness in the portion passing through the surface region 113, but the portion passing through the empty space 111 forms a relatively higher fineness than the yarn passing through the surface region 113. As a result, a yarn having a change in thickness may be formed in one continuous yarn.
상기 빈공간 111이 형성되는 롤러는 프론트롤러임이 바람직하며, 프론트롤러 중 톱롤러에 형성되면 더욱 바람직하다.The roller in which the empty space 111 is formed is preferably a front roller, and more preferably formed in the top roller among the front rollers.
상기 빈공간 111의 형상은 슬라이버가 롤러와 작용하는 폭 및 두께보다 일정 정도 더 크게 형성될 수 있으며, 빈공간 111은 롤러에 1 이상 형성될 수 있다. 상기 빈공간 111의 수로서 단위 길이당 효과 발생 빈도를 제어할 수 있는 특징이 있다. 또한 폭(L)의 길이에 따라 효과 발생 길이도 제어될 수 있음은 물론이다.The shape of the empty space 111 may be formed to be larger than the width and thickness of the sliver acting on the roller, and the empty space 111 may be formed at least one on the roller. As the number of the empty spaces 111, the frequency of effect occurrence per unit length can be controlled. In addition, the length of effect generation can also be controlled according to the length of the width (L).
또한 상기 효과는 드래프트비를 제어함으로서 제어될 수 있는데, 도 1에 도시된 바와 같이 MVS 시스템의 드래프트영역은, 프론트롤러, 2nd롤러, 3rd롤러, 백롤러 4행구조로 이루어질 수 있는데, 여기서 프론트롤러와 2nd 사이의 드래프트비를 MDR(Main Draft Ratio), 2nd롤러와 3rd롤러 사이의 드래프트비를 IDR((Intermediate Draft Ratio), 3rd롤러와 백롤러 사이의 드래프트비를 BDR(Break Draft Ratio)로 정의할 때 통상 드래프트비 대비 MDR를 낮게 하고 IDR를 높게 하였을 때, 효과 구간의 굵기가 더 굵어지는 현상이 발생하였고, 이와 반대인 경우 굵기는 작아졌다. 본 발명자들의 다수의 시험결과 상기 IDR 값이 2.0 내지 2.1 정도일 때 방출성 및 적정 효과효과 측면에서 바람직한 사가 형성되었다.In addition, the effect can be controlled by controlling the draft ratio. As shown in FIG. 1, the draft region of the MVS system may include a front roller, a 2nd roller, a 3rd roller, and a back roller four-row structure, where the front roller is used. The draft ratio between and 2nd is defined as MDR (Main Draft Ratio), the draft ratio between 2nd and 3rd roller is defined as IDR ((Intermediate Draft Ratio), draft ratio between 3rd and back roller as BDR (Break Draft Ratio) When the MDR is lowered and the IDR is higher than the draft ratio, the thickness of the effect section becomes thicker, and the thickness becomes smaller in the opposite case. When about 2.1 to about 2.1 preferred yarns were formed in terms of release properties and moderate effects.
한편 상기 효과는 슬라이버의 공급량으로서도 제어될 수 있는데, 슬라이버의 공급량이 증가함에 따라 효과 특히 슬럽의 두께가 커지는 것으로 시험되었다. 슬라이버의 공급량이 증가함에 따라 전체 드래프트비가 상승하므로 상대적으로 드래프트 작용을 받지 않는 슬럽구간의 두께가 상승하는 것으로 판단된다.On the other hand, the effect can also be controlled as the feed amount of the sliver, which was tested as the effect, in particular, the thickness of the slug, increased as the feed amount of the sliver increased. As the feed rate of the sliver increases, the overall draft ratio increases, so the thickness of the slab section that is relatively undrafted seems to increase.
또한 상기 빈공간 111은 일정한 폭과 두께의 직사각형 뿐만 아니라, 원형, 타원형, 삼각형, 마름모, 별 등 어떠한 형상으로도 구현될 수 있는데, 롤러 상에 상기 형상의 위치나 크기에 따라 사에 다양한 효과 구현이 가능하다. 비제한적인 예로서 삼각형의 경우 삼각형의 밑변영역과 꼭지점을 통과하는 슬라이버는 드래프트 정도를 달리할 수 있어 마치 슬럽이 그라디에이션 효과와 같은 효과가 발생될 수도 있다.In addition, the empty space 111 may be implemented in any shape such as a circle, an oval, a triangle, a rhombus, a star, as well as a rectangle having a constant width and thickness, and realizes various effects on yarn according to the position or size of the shape on a roller. This is possible. As a non-limiting example, in the case of a triangle, the sliver passing through the base and the vertex of the triangle may have a different degree of draft, so that an effect such as a sloping gradient may occur.
본 발명에 의한 효과사는 링정방에 의한 효과사 특히 슬럽사로 대비할 때 사 표면의 잔털이 적어 뻣뻣한 느낌이 구현되며 외관이 깨끗한 장점이 있다. 또한 잔털이 적으므로 항필링성이 우수하고 세탁내구성도 우수한 특성이 발현된다.The effect yarn according to the present invention has a small stiffness on the surface of the yarn when compared to the effect yarn by the ring square, in particular the slop yarn is implemented stiff feeling and has the advantage of clean appearance. In addition, since there is little hair, the anti-pilling property is excellent and the washing durability is also excellent.
