본 발명은 복합 가연사의 제조방법과 이를 이용한 직물에 관한 것이며, 더욱 상세하게는 구성 성분사의 방사속도와 가연 공정의 조정을 통해 자연스러우면서도 선명한 톤온톤의 투톤 효과의 발현이 가능한 복합 가연사의 제조방법과 이를 이용하여 제조되는 투톤 효과의 직물에 관한 것이다.The present invention relates to a method for manufacturing a composite false-twist yarn and a fabric using the same, and more particularly, a method for producing a composite false-twist yarn capable of expressing a two-tone effect of natural and vivid tone-on-tone through adjustment of the spinning speed and the false-twisting process of the constituent yarns, and It relates to a two-tone effect fabric manufactured using this.
주지하는 것과 같이, 합성 필라멘트사를 인장시키면서 열을 부여함과 동시에 꼬임을 주었다가 풀어주면 인공적인 권축이 부여되어 신축성과 벌키성이 향상되는데, 이와 같이 가연, 열고정, 해연을 한 공정에서 실시하여 신축사를 제조하는 것을 가연(false twist)가공이라 하고, 이렇게 가공된 실을 가연사(假撚絲)라고 한다.As is well known, when the synthetic filament yarn is stretched, heat is applied, and twisted and released at the same time, artificial crimp is given and elasticity and bulkiness are improved. The fabrication of the stretched yarn is called false twist processing, and the processed yarn is called false twisted yarn.
이러한 가연사는 스웨터, 슬랙스, 수영복, 양말, 타이츠 등의 편물과 직물을 만드는 데에 널리 사용되어 왔다.Such false twist yarns have been widely used to make knitwear and fabrics such as sweaters, slacks, swimwear, socks, and tights.
근래에는 이러한 가연가공을 응용하여 투톤 효과나 표면 텍스쳐 변화와 같은 다양한 표면 효과를 갖는 가연사들이 소개되고 있다.In recent years, false twisted yarns having various surface effects such as a two-tone effect or a change in surface texture have been introduced by applying such false twist processing.
그 일례로, 한국 등록특허공보 제10-0220221호 공보에는, 부분배향사를 2단으로 열처리하여 가연 가공함에 있어서, 핫핀의 온도 및 핫핀 전후의 연신비를 제어함과 동시에, 가연 연수 및 1차 히터 온도의 미세조정에 의하여 최종 가공사의 멜란지한 투톤이 발현되기에 적합한 비수수축률, 크림프율, 투톤점유비 등을 갖는 투톤이 발현되는 폴리에스터 신축가공사의 제조방법이 개시되어 있다.As an example, in Korean Patent Application Publication No. 10-0220221, in the case of performing false-twist processing by heat-treating the partial oriented yarn in two stages, the temperature of the hot pin and the draw ratio before and after the hot pin are controlled, and the false twist number and the primary heater are Disclosed is a method for producing a polyester new construction in which two-tones having a non-shrinkage ratio, a crimp ratio, a two-tone share ratio, etc., which are suitable for expressing the melange two-tones of the final processed yarn by fine adjustment of temperature, are disclosed.
또한, 특수한 원사나 물성이 다른 이종의 필라멘트 원사를 가연기에서 교락하여 복합 가연사를 제조함으로써, 투톤 효과를 내는 기술과 관련하여서도 알려져 있다.In addition, it is also known in connection with a technique of producing a two-tone effect by manufacturing a composite false twisted yarn by intersecting special yarns or different types of filament yarns with different physical properties in a false twisting machine.
예컨대, 대한민국 특허공보 특1995-0004072호 공보에는, 복굴절율과 건열수축률의 차이가 나는 고배향 폴리에스터 미연신사와 저배향 폴리에스터 미연신사를 교락처리한 다음, 요입부를 일정한 간격으로 형성시킨 변형열판을 통과시켜 연신하고 가연하여, 직물 제조시에 표면에 요철이 형성되고, 불규칙한 염색효과를 가지며 드레이프성이 우수한 복합가공사의 제조방법이 기재되어 있다.For example, in Korean Patent Publication No. 1995-0004072, a deformed hot plate in which high orientation polyester undrawn yarn and low orientation polyester undrawn yarn having a difference between birefringence and dry heat shrinkage are entangled, and then concave portions are formed at regular intervals. A method of manufacturing a composite fabrication work having an irregular dyeing effect and excellent drape property is described, which is stretched and twisted by passing through the fabric to form irregularities on the surface during fabric manufacture.
상술한 방법들은 모두 한 가닥의 필라멘트사를 가연하거나, 또는 두 가닥의 필라멘트 섬유사를 교락하여 하나로 만든 다음 함께 가연 가공하는 방식을 사용하여, 균일한 믹스가 이루어진 멜란지한 투톤 효과를 얻는 것을 특징으로 하고 있어, 제조원가가 높은 단점이 있으며, 톤온톤 효과가 확실하고 좀 더 자연스러운 느낌의 투톤 효과의 사나 직물을 요구하는 수요는 만족시키지 못하고 있다. All of the above-described methods are characterized in that a single filament yarn is twisted or two filament yarns are entangled into one and then false twisted together to obtain a melange two-tone effect with a uniform mix. As a result, manufacturing cost is high, and the demand for two-tone yarns or fabrics with a more natural feel and tone-on-tone effect is not satisfied.
본 발명은 상술한 것과 같은 종래기술의 문제점을 해결하기 위한 것으로서, 레귤러 부분배향 폴리에스테르 필라멘트사를 사용하여, 내츄럴 투톤 효과의 발현이 가능한 복합 가연사를 제조하는 방법 및 이를 이용한 투톤 효과를 갖는 직물지를 제공하는 것을 목적으로 한다.The present invention is to solve the problems of the prior art as described above, a method for producing a composite false twist yarn capable of expressing a natural two-tone effect by using a regular partially oriented polyester filament yarn, and a textile paper having a two-tone effect using the same It aims to provide.
상기 목적을 달성하기 위한 본 발명에 따른 투톤 발현이 가능한 복합 가연사의 제조방법은,A method for producing a composite false twist yarn capable of two-tone expression according to the present invention for achieving the above object,
방사속도가 3,500m/min 이상이고, 신도가 50~130%이며, 단섬도가 2~6데니어이고, 멀티필라멘트섬도가 40~600데이어인 레귤러 폴리에스테르 부분배향사를 제1성분사로 하고, A regular polyester partially oriented yarn having a spinning speed of 3,500m/min or more, an elongation of 50 to 130%, a single fineness of 2 to 6 denier, and a multifilament fineness of 40 to 600 days as the first component yarn,
방사속도가 3,000m/min이하이고, 신도가 120~200%이며, 단섬도가 0.5~4데니어이고, 멀티필라멘트섬도가 40~600데니어인 레귤러 폴리에스테르 부분배향사를 제2성분사로 하여,Using regular polyester partially oriented yarn with a spinning speed of 3,000m/min or less, an elongation of 120 to 200%, a single fineness of 0.5 to 4 denier, and a multifilament fineness of 40 to 600 denier as the second component yarn,
상기 제1성분사와 제2성분사를 각각 동시에 복합 가연가공기에 투입하여, 상기 제1성분사의 연신비율을 1.0~1.5로 하고, 제2성분사의 연신비율은 1.6~2.2로 달리하여 동시에 각각 연신-냉각-가연하여 얻어진 각 성분사의 가연사를, 동일한 복합 가연가공기에서 연속적으로 합사하고 에어노즐을 이용하여 부분적으로 교락하여 복합가연사를 형성하는 것을 특징으로 한다.The first component yarn and the second component yarn are added to the composite false-twisting machine at the same time, so that the stretching ratio of the first component yarn is set to 1.0 to 1.5, and the stretching ratio of the second component yarn is changed to 1.6 ~ 2.2, and each of them is drawn at the same time. It is characterized in that the false twisted yarn of each component yarn obtained by cooling-twisting is successively laminated in the same complex false twisting machine and partially entangled using an air nozzle to form a composite false twisted yarn.
본 발명에 따른 투톤 발현이 가능한 복합 가연사를 이용한 직물은,The fabric using the composite false twist yarn capable of two-tone expression according to the present invention,
상기 본 발명의 방법에 의해 제조된 투톤 발현이 가능한 복합 가연사를 경사 또는 위사 성분으로 전부 또는 일부 사용하여 이루어지며, 제1성분사와 제2성분사의 염색농도 차이에 의해 투톤 효과를 갖는 것을 특징으로 한다.It is made by using all or part of the composite false twisted yarn capable of expressing two-tones prepared by the method of the present invention as a warp or weft component, and has a two-tone effect due to the difference in dyeing concentration of the first component yarn and the second component yarn. do.
본 발명에 따라 제조되는 복합 가연사는 제1성분사와 제2성분사로 사용되는 부분배향사의 방사속도와 가연과정에서의 연신비의 차이에 의해 복합 가연사 상태 또는 이를 제직한 직물상태에서 염색시에 제1성분사와 제2성분사간의 염색성의 차이로 인해 선명하면서도 내츄럴한 투톤 효과의 발현이 가능하다.The composite false-twisted yarn manufactured according to the present invention is the first component when dyeing in the state of the composite false-twisted yarn or the state of the fabric woven by the difference between the spinning speed of the partial oriented yarn used as the first component yarn and the second component yarn and the draw ratio during the twisting process. Due to the difference in dyeing properties between the component yarn and the second component yarn, it is possible to express a vivid and natural two-tone effect.
본 발명에 따라 제조되는 복합 가연사는 방사속도만 조정한 레귤러 PET 부분배향사를 사용하여 제조되기 때문에, 원착사나 저온 융착사 등의 다른 특수한 사를 이용하여 복합 가공사를 제조하거나 투톤효과를 발현하는 것에 비해 원가 절감의 효과가 크다.Since the composite false twist yarn produced according to the present invention is produced using regular PET partially oriented yarn with only the spinning speed adjusted, it is possible to manufacture composite processed yarn using other special yarns such as original yarn or low-temperature fusion yarn or to express a two-tone effect. Compared to this, the cost reduction effect is great.
또한, 한 번의 복합가연공정을 통해 투톤 효과의 발현이 가능한 복합 가연사를 얻을 수 있기 때문에, 제조원가가 절감되는 효과가 있다.In addition, since it is possible to obtain a composite false twisted yarn capable of expressing a two-tone effect through a single composite false twisting process, there is an effect of reducing the manufacturing cost.
특히, 이중DR 및 더블유니트를 사용하여 1추에서 동시에 복합 가연사를 제조할 수 있어, 생산량 감소가 발생하지 않아 제조원가 절감에 효과가 크다.In particular, since the double DR and double unit can be used to manufacture composite false twisted yarn from one weight at the same time, there is no reduction in production, so it is highly effective in reducing manufacturing cost.
본 발명의 방법에 의해 제조되는 복합 가연사는 제1성분사와 제2성분사가 최종 교락 이전까지 별개로 각각 연신 및 가연이 이루어지기 때문에, 가공 공정중에 각 구성 성분사의 멀티필라멘트끼리 혼섬이 이루어지지 않아, 내츄럴한 투톤 효과가 선명하게 나타나 뛰어난 장식 효과를 발휘할 수 있는 이점이 있다.Since the composite false-twist yarn manufactured by the method of the present invention is separately stretched and twisted until the first component yarn and the second component yarn before the final entanglement, the multifilaments of each component yarn are not mixed together during the processing process. There is an advantage that the natural two-tone effect can be clearly displayed to exert an excellent decorative effect.
또한, 구성 성분사의 섬도 차이나 연신비의 조정 등을 통해, 투톤 효과의 정도를 다양하게 조정할 수 있는 이점이 있다.In addition, there is an advantage in that the degree of the two-tone effect can be variously adjusted through adjustment of the difference in fineness of the constituent yarns or the stretching ratio.

이하, 본 발명을 좀 더 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명에 따른 투톤 발현이 가능한 복합 가연사의 제조방법은, 통상 사용하는 레귤러 폴리에스테르를 사용하되 복합 가연에 의해 하나의 실에서 2가지의 구성 성분사가 농담을 달리하는 투톤 효과로 염색이 가능하도록 한 것이다.The method for producing a composite false twist yarn capable of two-tone expression according to the present invention uses a regular polyester that is normally used, but allows two constituent yarns to be dyed in a two-tone effect of different shades and shades in one yarn by composite twisting. will be.
즉, 레귤러 폴리에스테르 부분배향사를 사용하되, 방사속도에 차이가 있는 멀티필라멘트사를 조합하여 복합 가연화하고, 이 과정에서 연신비를 달리 함으로써, 배향도와 결정화도의 차이를 통해 염색성의 차이를 극대화한다.In other words, regular polyester partially oriented yarn is used, but multifilament yarns with different spinning speeds are combined to be compositely softened, and by varying the draw ratio in this process, the difference in dyeability is maximized through the difference in orientation and crystallinity. .
상기 레귤러 폴리에스테르 부분배향사는, 분자구조를 개량하여 이루어진 저온 융착사나 저온 염색이 가능한 폴리에스테르, 카티온 가염성 폴리에스테르나, 극세사와 같은 특수한 섬유가 아니라, 가연사 제조용 등으로 일반적으로 사용하는 분자구조와 섬도의 폴리에스테테르를 의미한다.The regular polyester partially oriented yarn is not a special fiber such as low-temperature fused yarn made by improving the molecular structure, low-temperature dyeable polyester, cation flame retardant polyester, or microfiber, but a molecule generally used for manufacturing false-twisted yarn, etc. It means a polyester of structure and fineness.
다만, 본 발명에서는 방사속도의 조절에 의해 신도 등의 물성 차이가 있는 2종의 레귤러 폴리에스테르 부분배향사로 된 멀티필라멘트사를 구성 성분사로 사용하여 복합 가연사를 제조한다.However, in the present invention, a composite false twisted yarn is manufactured by using a multifilament yarn made of two kinds of regular polyester partially oriented yarns having a difference in physical properties such as elongation by controlling the spinning speed as a component yarn.
상기 2종의 구성 성분사의 제1성분사로는, 방사속도가 3,500m/min 이상이고 신도가 50~130%이며, 단섬도가 2~6데니어, 멀티필라멘트섬도가 40~600데이어인 레귤러 폴리에스테르 부분배향사를 사용하고, 제2성분사로는 방사속도가 3,000m/min 이하이고 신도가 120~200%이며, 단섬도가 0.5~4데니어, 멀티필라멘트섬도가 40~600데니어인 레귤러 폴리에스테르 부분배향사를 사용한다.As the first component yarn of the two constituent yarns, a regular polyester having a spinning speed of 3,500 m/min or more, an elongation of 50 to 130%, a single fineness of 2 to 6 denier, and a multifilament fineness of 40 to 600 days. Partial oriented yarn is used, and as the second component yarn, the spinning speed is 3,000m/min or less, the elongation is 120~200%, the single fineness is 0.5~4 denier, and the multifilament fineness is 40~600 denier. Orienting yarn is used.
상기 제1성분사와 제2성분사는 복합 가연가공기에 동시에 투입하여, 연신비를 달리하면서 각각 가연하고, 합사하여 에어노즐을 통해 교락하여 하나의 복합 가연사를 형성하도록 한다.The first component yarn and the second component yarn are simultaneously introduced into a composite false twisting machine, each of which is false twisted while varying the draw ratio, and fused together to form one composite false twisted yarn by entanglement through an air nozzle.
본 발명에서 사용하는 복합 가연가공기(100)는 도 1에 나타낸 것과 같이, 한 쌍의 제1공급롤러(10A,10B)를 이용하여 2가닥의 원사(P0Y1, POY2)를 각각 투입할 수 있도록 구성되고, 이어서 제1히터(20), 냉각판(30) 및 한 쌍의 트위스트 디스크 또는 벨트로 이루어진 한 쌍의 가연부(40A,40B), 상기 가연부를 각각 통과하여 가연이 이루어진 2가닥의 가연사를 합사하는 합사 가이드(50), 제2공급롤러(61), 상기 합사된 가연사에 에어젯을 분사하여 인터레이싱하는 인터레이싱 노즐(70), 제3공급롤러(62), 제2히터(80)를 통해 일체화된 복합가연사(1)를 권취하는 권취롤러(90)를 포함하여 구성된다.As shown in Fig. 1, the composite
이러한 구성에 의해, 상기 한 쌍의 제1공급롤러(10A, 10B)와 제2공급롤러(61) 사이의 속도 차이에 의해 상기 부분배향사인 제1성분사와 제2성분사의 연신비를 조정할 수 있으며, 이 연신비의 차이에 의해 배향도와 결정화도의 차이를 발생시켜, 염색성에 차이가 있는 2가닥의 가연사가 합사 및 교락된 복합가연사(1)를 형성하게 된다. With this configuration, the draw ratio of the first component yarn and the second component yarn as the partial oriented yarn can be adjusted by the difference in speed between the pair of
본 발명에서는 상기 제1성분사의 연신비를 1.0~1.5로 하고, 제2성분사의 연신비는 1.6~2.2로 하여 상기 복합 가연가공기에서 각각 연신-냉각-가연한 후에 열고정하여 가연사를 형성한다. 이와 같이, 연신비가 차이가 나면 연신비가 낮은 제1성분사는 배향도와 결정화도가 낮아져서 염색성이 높아, 동일 조건으로 염색시에 진하게 염색이 이루어지며, 연신비가 높은 제2성분사는 배향도와 결정화도가 높아 연하게 염색이 되어 투톤효과의 염색사를 얻을 수 있다.In the present invention, the draw ratio of the first component yarn is set to 1.0 to 1.5, and the draw ratio of the second component yarn is set to 1.6 to 2.2, respectively, followed by drawing-cooling-warming in the composite false twisting machine, followed by heat setting to form false twisted yarn. As described above, if the draw ratio is different, the orientation and crystallinity of the first component yarn with a low draw ratio decreases, so that the dyeing property is high. When dyeing under the same conditions, the second component yarn with a high draw ratio is dyed with a high degree of orientation and crystallinity. It is dyed to obtain a two-tone dyed yarn.
상기와 같이 가연이 이루어진 제1성분사와 제2성분사의 가연사는, 합사 가이드(50)를 통과하면서 합사된 후, 인터레이싱 노즐(70)에서의 에어노즐의 분사에 의해 교락되어 본 발명에 따른 복합 가연사(1)를 형성한다. 인터레이싱 노즐의 전방에는 제3공급롤러(62)를 배치하여, 인터레이스의 간격을 조절할 수 있다.The false-twisted yarns of the first component yarn and the second component yarn, which have been false-twisted as described above, are bonded while passing through the
이때, 에어노즐의 압력을 통상의 경우보다 낮은 1.0㎏/㎠ 미만, 바람직하게는 0.1~0.5㎏/㎠로 하여 제1, 제2성분사로부터 형성된 가연사끼리의 접합부위를 최소화하여 염색성이 다른 두 가연사가 엉켜서 색상이 서로 혼합되지 않도록 함으로써, 좀 더 선명하고 내츄럴한 투톤효과를 나타내고, 평활도가 높은 블라인드용 직물 등의 제직시 커버력이 약한 교락점 부분에 핀홀 형태의 결함이 나타나지 않도록 한다.At this time, the pressure of the air nozzle is less than 1.0kg/cm2, preferably 0.1~0.5kg/cm2, which is lower than the usual case to minimize the junction between false-twisted yarns formed from the first and second component yarns, so that the dyeability is different. By preventing the two false twisted yarns from being tangled and mixing colors, it shows a more vivid and natural two-tone effect, and prevents pinhole-shaped defects from appearing at the intersection points where the coverage is weak when weaving blind fabrics with high smoothness.
실시예Example
제1성분사로 방사속도 3,800m/min의 폴리에스테르 부분배향사 520d/96f, 신도 95%의 멀티필라멘트사를 사용하고, 제2성분사로 방사속도 2,600m/min, 신도 145%의 폴리에스테르 부분배향사 300d/96f의 멀티필라멘트사를 도 1에 나타낸 복합 가연가공기에 투입하여 히터 및 냉각판을 거친 후, 가연하여 노즐 위에 배치된 합사 가이드를 이용하여 합사하고, 인터레이싱 노즐을 이용하여 인터레이싱하여 투톤 발현이 가능한 복합 가연사를 제조하였으며, 이렇게 얻은 복합 가연사를 위사로 사용하여 롤스크린용 직물을 제직하였다. Partially oriented polyester yarn 520d/96f with a spinning speed of 3,800m/min and multifilament yarn with an elongation of 95% is used as the first component yarn, and partial oriented polyester with a spinning speed of 2,600m/min and an elongation of 145% as the second component yarn After inserting the multifilament yarn of 300d/96f yarn into the composite false twisting machine shown in Fig. 1, passing through the heater and cooling plate, twisting the yarn and twisting it using a braiding guide disposed on the nozzle, interlacing using an interlacing nozzle. A composite false-twist yarn capable of two-tone expression was prepared, and the obtained composite false-twist yarn was used as a weft yarn to weave a fabric for a roll screen.
이때, 제1성분사의 경우, 제1공급롤러와 제2공급롤러 사이의 연신비를 1.3으로 하고, 제1히터 온도 200℃, 제2히터 온도 220℃, 가연부의 D/Y를 2.2(Disk speed/Yarn speed)로 하였다. 또한, 제2성분사의 경우, 연신비를 1.9로 하고, 제1히터 온도를 200℃, 제2히터 온도는 220℃로 설정하였으며, 가연부의 D/Y는 1.8이었다. 제1가연부의 D/Y는 상대적으로 높게 하여 모우가 발생하지 않도록 조정하고, 제2가연부의 D/Y는 낮게 하여 미해연의 발생이 적어지도록 하였다.At this time, in the case of the first component yarn, the draw ratio between the first feed roller and the second feed roller is 1.3, the first heater temperature is 200°C, the second heater temperature is 220°C, and the D/Y of the combustible part is 2.2 (Disk speed/ Yarn speed). In the case of the second component yarn, the draw ratio was set to 1.9, the first heater temperature was set to 200°C, the second heater temperature was set to 220°C, and the D/Y of the combustible part was 1.8. The D/Y of the first combustible part was set relatively high so as not to generate wool, and the D/Y of the second combustible part was lowered to reduce the occurrence of unsealed smoke.
