Description
본 발명은 항균성 및 신축성이 우수한 리사이클 폴리에스테르 복합가연가공사의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing recycled polyester composite false twisted fabric with excellent antibacterial properties and elasticity.
전세계적으로 지구온난화 문제가 이슈화되면서 섬유산업분야에서도 환경보존을 위한 친환경 섬유 기술개발에 대한 관심이 급증되고 있으며, 그 일환으로서 리사이클 소재의 가치가 급부상하고 있는 실정이다.As global warming has become an issue around the world, interest in developing eco-friendly fiber technology for environmental preservation is rapidly increasing in the textile industry, and as part of this, the value of recycled materials is rapidly rising.
최근 ZARA, Patagonia등의 글로벌 패션 브랜드들이 지구의 환경 문제를 적극 대처하기 위하여 리사이클 섬유소재의 사용비율을 높이고 있어 PET 리사이클 섬유의 수요가 점차 증가하는 추세이다.Recently, global fashion brands such as ZARA and Patagonia are increasing the rate of use of recycled fiber materials in order to actively respond to the Earth's environmental problems, and the demand for PET recycled fiber is gradually increasing.
이러한 추세에 대응하여 화섬업체들에서는 PET 리사이클 원사로서 세섬도이면서도 소프트한 촉감을 가지고 경량, 항균성, 신축성 등의 2가지 이상의 다기능성을 가지는 차별화된 기능성을 가진 리사이클 섬유소재가 꾸준히 요구되고 있으나, 대부분 폐PET병을 활용하여 기능성이 없는 정번품 소재 또는 단일기능성만을 발현하는 소재의 개발에 그치고 있는 실정이다. In response to this trend, chemical fiber companies are continuously demanding recycled PET recycled fiber materials with differentiated functionality such as fineness yet soft to the touch and two or more multi-functional properties such as light weight, antibacterial properties, and elasticity. However, most The current situation is that the use of waste PET bottles is limited to the development of original materials without functionality or materials that only exhibit a single functionality.
특히, 잠재권축필라멘트와 같은 기능성 필라멘트에 리사이클 소재를 접목하는 시도는 아직 소개되고 있지 않다.In particular, attempts to combine recycled materials with functional filaments such as latent crimp filaments have not yet been introduced.
그러므로 본 발명에 의하면 리사이클 폴리에스테르를 이용하여 항균성을 통한 인체보호 효과, 신축성을 통한 통하여 의류로 제작시 편안한 착용감과 활동성을 부여할 수 있는 복합가연가공사를 제공하는 것을 기술적과제로 한다.Therefore, according to the present invention, the technical task is to provide a composite false twisted fabric that can provide a comfortable fit and activity when made into clothing through the protection of the human body through antibacterial properties and elasticity using recycled polyester.
그러므로 본 발명에 의하면, 리사이클 잠재권축필라멘트를 공급하여 제1피드롤러로 공급하여 180~190℃로 제1차히터에서 제1차열처리한 후, 벨트각도가 95~105°인 벨트식가연기를 통과시켜 사속비(VR) 1.32~1.42로 가연을 하고 제2피드롤러를 통과시키고, 인터레이스노즐의 구경 1.4~1.6 ㎜, 에어압 1.2~1.8kg/㎠으로 인터레이스하고, 400~450m/분으로 권취롤러로 권취하는 것을 특징으로 하는 항균성 및 신축성이 우수한 리사이클 폴리에스테르 복합가연가공사의 제조방법이 제공된다.Therefore, according to the present invention, the recycled latent crimp filament is supplied to the first feed roller, subjected to primary heat treatment in the primary heater at 180 to 190°C, and then passed through a belt-type flaming machine with a belt angle of 95 to 105°. It is false twisted at a yarn speed ratio (VR) of 1.32~1.42, passed through the second feed roller, interlaced with an interlace nozzle diameter of 1.4~1.6 mm, air pressure of 1.2~1.8kg/㎠, and wound roller at 400~450m/min. A manufacturing method of recycled polyester composite false twisted fabric with excellent antibacterial properties and elasticity is provided, which is characterized by winding.
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 항균성 및 신축성이 우수한 리사이클 폴리에스테르 복합가연가공사의 제조방법은 리사이클 잠재권축필라멘트를 사용하여 항균성과 신축성을 최대로 발현하기 위한 복합가연사 제조방법으로서 리사이클 잠재권축필라멘트를 가연을 하고 인터레이스하고 권취하게 된다.The manufacturing method of the recycled polyester composite false twisted yarn with excellent antibacterial properties and elasticity of the present invention is a method of manufacturing composite false twisted yarn for maximizing antibacterial properties and elasticity using recycled latent crimped filaments. The recycled latent crimped filaments are false twisted, interlaced, and wound. I do it.
우선, 원사로 사용되는 리사이클 잠재권축필라멘트에 관해 설명하기로 한다.First, we will explain the recycled latent crimp filament used as yarn.
리사이클 잠재권축필라멘트는 고유점도 0.4~0.55㎗/g인 저점도 폴리에스테르 수지칩을 별도의 익스트루더로 용융하고, 고유점도 0.57~0.70㎗/g인 리사이클 폴리에스테르 수지칩과 평균 입자 크기가 500~700㎚인 제올라이트 미세입자 0.5~1.0중량%함유 마스터배치칩을 별도의 익스트루더로 용융한 후, 310~330℃로 가열된 땅콩형단면을 가지는 방사구금에 함께 투입하여 방사한 후 3800~4200m/분의 속도로 권취하여 제조된 것이 열수축율이 다른 PET 고분자에 의해 우수한 신축성 발현으로 의류로 제작 및 의복 착용시 편안한 착용감과 활동성을 부여하며 잠재권축필라멘트에 첨가되는 있는 항균 물질로 균의 증식을 억제하는 특성을 통한 인체친화적인 특성을 부여하여 2가지 이상 기능성을 동시발현할 수 있어 바람직하다.Recycled latent crimp filament is made by melting low-viscosity polyester resin chips with an intrinsic viscosity of 0.4 to 0.55 ㎗/g using a separate extruder, and recycled polyester resin chips with an intrinsic viscosity of 0.57 to 0.70 ㎗/g and an average particle size of 500. A masterbatch chip containing 0.5-1.0% by weight of ~700㎚ zeolite fine particles is melted using a separate extruder, and then put into a spinneret with a peanut-shaped cross-section heated to 310-330℃ and spun at 3800~3800℃. Manufactured by winding at a speed of 4200m/min, PET polymers with different heat shrinkage rates exhibit excellent elasticity, providing comfortable fit and activity when made into clothing and worn. Antibacterial substances added to the latent crimped filament prevent the growth of bacteria. It is desirable because it can express two or more functionalities simultaneously by providing human-friendly characteristics through the property of suppressing .
본 발명의 리사이클 잠재권축필라멘트는 고유점도 0.4~0.55㎗/g인 저점도 폴리에스테르 수지칩과 고유점도 0.57~0.70㎗/g인 리사이클 폴리에스테르 수지칩(제올라이트 미세입자 0.5~1.0중량%함유)을 원료로 하여 저점도와 고점도의 비율을 중량비 45:55~50:50으로 한다. The recycled latent crimp filament of the present invention is a low-viscosity polyester resin chip with an intrinsic viscosity of 0.4 to 0.55 dl/g and a recycled polyester resin chip (containing 0.5 to 1.0% by weight of zeolite fine particles) with an intrinsic viscosity of 0.57 to 0.70 dl/g. Using raw materials, the ratio of low viscosity to high viscosity is set to a weight ratio of 45:55 to 50:50.
상기 고유점도 0.4~0.55㎗/g인 저점도 폴리에스테르 수지칩은 일반 저점도 폴리에스테르 수지칩 또는 리사이클 저점도 폴리에스테르 수지칩을 사용할 수 있는데, 리사이클 저점도 폴리에스테르 수지칩을 사용하는 경우에는 전체 잠재권축 필라멘트가 100% 리사이클 수지로 이루어지게 되는 것이다.The low-viscosity polyester resin chip with an intrinsic viscosity of 0.4 to 0.55 ㎗/g can be used as a general low-viscosity polyester resin chip or a recycled low-viscosity polyester resin chip. If recycled low-viscosity polyester resin chip is used, the entire low-viscosity polyester resin chip can be used. The latent crimp filament is made of 100% recycled resin.
상기 저점도 폴리에스테르 수지칩과 리사이클 폴리에스테르 수지칩은 방사를 위해서 준비단계로 건조공정을 거쳐 수지칩내의 수분율을 30~40ppm 이하로 한다. 이렇게 건조된 저점도 폴리에스테르 수지칩은 고유점도 0.4~0.55㎗/g인 것이 바람직하며, 고점도 폴리에스테르 칩은 고유점도 0.57~0.70㎗/g인 것을 사용하는 것이 권축신장율과 탄성회복율이 매우 우수한 잠재권축성능을 나타내는데 바람직하다.The low-viscosity polyester resin chips and recycled polyester resin chips undergo a drying process as a preparatory step for spinning, and the moisture content in the resin chips is set to 30 to 40 ppm or less. The low-viscosity polyester resin chips dried in this way preferably have an intrinsic viscosity of 0.4 to 0.55 ㎗/g, and the high-viscosity polyester chips have an intrinsic viscosity of 0.57 to 0.70 ㎗/g as they have excellent crimp elongation and elastic recovery rates. It is desirable to show crimp performance.
평균 입자 크기가 500~700㎚인 제올라이트 미세입자 0.5~1.0중량%함유 마스터배치칩은 고유점도 0.57~0.70㎗/g인 리사이클 폴리에스테르 부분에 항균성의 기능성을 부여하기 위한 것으로서 리사이클 폴리에스테르 수지칩과 제올라이트 미세입자 0.5~1.0중량%함유 마스터배치칩은 별도의 315~325℃로 가열된 익스트루더로 용융시키게 된다. The masterbatch chip containing 0.5 to 1.0% by weight of zeolite microparticles with an average particle size of 500 to 700 nm is intended to provide antibacterial functionality to the recycled polyester portion with an intrinsic viscosity of 0.57 to 0.70 ㎗/g, and is used as a recycled polyester resin chip and Masterbatch chips containing 0.5 to 1.0% by weight of zeolite fine particles are melted using a separate extruder heated to 315 to 325°C.
상기 제올라이트 미세입자는 0.5~1.0중량%함유되는 것이 복합방사할 경우 방사 작업성이 양호하였으며, 원사의 외관상 형태 안정성이 양호하다. 1.0중량%를 초과하는 경우에는 고화 및 권취시 불규칙하게 단사절이 발생하였으며 구금이 부분적으로 막히는 등 작업 효율성이 저하되는 현상이 발생할 수 있다.When 0.5 to 1.0% by weight of zeolite fine particles were used for composite spinning, spinning workability was good, and the apparent shape stability of the yarn was good. If it exceeds 1.0% by weight, work efficiency may be reduced, such as irregular single yarn breakage during solidification and winding, and partial blockage of the spinneret.
또한, 저점도 폴리에스테르 수지칩을 별도의 익스트루더로 용융하고, 이후 각각의 용융물을 310~330℃로 가열된 방사구금에 동시에 투입하게 된다. 방사구금은 잠재권축필라멘트를 제조하는 통상의 땅콩형단면을 가지는 방사구금을 사용하여 방사한다. In addition, low-viscosity polyester resin chips are melted using a separate extruder, and then each melt is simultaneously introduced into a spinneret heated to 310-330°C. The spinneret is spun using a spinneret with a typical peanut-shaped cross-section that produces latent crimp filament.
이렇게 방사구금을 통해 방사한 후 냉각하고 3800~4200m/분의 속도로 권취하여 본 발명의 리사이클 폴리에스테르 복합가연가공사의 원사로 사용하게 된다.After spinning through a spinneret in this way, it is cooled, wound up at a speed of 3800 to 4200 m/min, and used as the yarn for the recycled polyester composite false twist work of the present invention.
이하에서는 상기 준비된 원사를 이용하여 복합가연사를 제조하는 공정에 대하여 설명하기로 한다.Hereinafter, the process for manufacturing composite false-twisted yarn using the prepared yarn will be described.
도 1에 도시된 바와 같이, 본 발명의 리사이클 폴리에스테르 복합가연가공사의 제조방법은 리사이클 잠재권축필라멘트를 공급하여 제1피드롤러로 공급하여 180~190℃로 제1차히터에서 제1차열처리한 후, 벨트각도가 95~105°인 벨트식가연기를 통과시켜 사속비(VR) 1.32~1.42로 가연을 하고 제2피드롤러를 통과시킨다.As shown in Figure 1, the manufacturing method of the recycled polyester composite false twisted fabric of the present invention involves supplying recycled latent crimp filament to the first feed roller and performing primary heat treatment in the primary heater at 180-190°C. Afterwards, it passes through a belt-type false twisting machine with a belt angle of 95 to 105°, and is twisted at a yarn speed ratio (VR) of 1.32 to 1.42, and then passes through the second feed roller.
보다 상세하게는 리사이클 잠재권축필라멘트(1)를 제1피드롤러(2)로 공급하여 180~190℃의 제1차히터(3)에서 제1차열처리한다. More specifically, the recycled latent crimp filament (1) is supplied to the first feed roller (2) and subjected to primary heat treatment in the primary heater (3) at 180 to 190°C.
제1차히터는 온도가 180~190℃인 것이 바람직한데, 180℃ 미만이면 신축성이 좋지 않고, 190℃를 초과하면 부분적인 용융으로 인해 융착현상이 발생하는 문제가 있다. It is preferable that the temperature of the primary heater is 180-190℃. If it is less than 180℃, elasticity is not good, and if it exceeds 190℃, there is a problem of partial melting and fusion phenomenon.
이후 벨트각도가 95~105°인 벨트식가연기(4)를 통과시켜 가연을 하고 제2피드롤러(5)를 통과시키는데, 상기 가연시 사속비(VR)는 1.32~1.42인 것이 바람직한데, 1.32 미만이면 가연시 적절한 장력형성이 불가하여 인장강도와 인장신도가 감소되는 문제가 있다. 또한, 사속비가 1.42 초과인 경우, 장력이 과도하게 발생되어 부분절사가 발생하여 작업효율성 및 생산성이 저하된다.Afterwards, it is twisted by passing it through a belt-type false twisting machine (4) with a belt angle of 95 to 105 degrees, and then passing it through the second feed roller (5). The yarn speed ratio (VR) during the false twisting is preferably 1.32 to 1.42, and is preferably 1.32. If it is less than 100%, it is impossible to form appropriate tension when flammable, so there is a problem of reduced tensile strength and tensile elongation. In addition, when the thread speed ratio is greater than 1.42, excessive tension is generated and partial cutting occurs, which reduces work efficiency and productivity.
상기 제1피드롤러와 제2피드롤러간의 연신비(DR)는 1.01~1.09인 것이 바람직한데, 1.01 미만이면 가연이 미흡하여 섬도의 균일성이 저하되는 문제가 있다. 1.09 초과이면 과도한 장력발생으로 인하여 절사, 모우 등이 발생하여 작업효율성 저하 및 권취가 어렵다. It is preferable that the draw ratio (DR) between the first and second feed rollers is 1.01 to 1.09, but if it is less than 1.01, there is a problem that false twist is insufficient and the uniformity of fineness is reduced. If it exceeds 1.09, excessive tension causes cutting, hair, etc., which reduces work efficiency and makes winding difficult.
상기 가연후 제2피드롤러 통과후 인터레이스노즐(6)의 구경 1.4~1.6 ㎜, 에어압 1.2~1.8kg/㎠으로 인터레이스하여 섬유간 집속성을 보완하고, 400~450m/분으로 권취롤러(7)로 권취하여 본 발명의 복합가연가공사를 제조하게 된다. After passing through the second feed roller after the twisting, the interlacing nozzle (6) is interlaced with a diameter of 1.4 to 1.6 mm and an air pressure of 1.2 to 1.8 kg/cm2 to supplement the inter-fiber focusing, and the winding roller (7) is used at 400 to 450 m/min. ) to manufacture the composite false twisted fabric of the present invention.
인터레이스시 에어압이 1.2kgf/㎠ 미만이면 공급되는 공기의 압력 부족으로 인하여 충분히 교락되기 어렵고, 압력이 1.8kgf/㎠을 초과하면 공급되는 공기의 압력 과다로 인하여 원사끼리 엉켜져서 부분적으로 뭉치는 현상 및 부분 절사가 발생하게 될 수 있다.When interlacing, if the air pressure is less than 1.2kgf/㎠, it is difficult to entangle sufficiently due to insufficient air pressure, and if the pressure exceeds 1.8kgf/㎠, the yarns become entangled and partially bundle together due to excessive air pressure. and partial truncation may occur.
상기 제2피드롤러와 권취롤러간의 오버피드율(OF2)은 1.6~1.8%인 것이 바람직한데, 1.6%미만이면 과도한 장력에 의해 미해연의 문제점이 발생하여 모우가 발생할 확률이 높아져서, 결론적으로 품질 안정성이 저하되는 문제점을 내포하고 있다. 또한, 오버피드율이 1.8% 초과이면 가연시 부분적으로 뭉침현상 발생으로 인한 품질 균일성이 저하되며, 부분적으로 가연 및 해연 불량이 발생한다.It is preferable that the overfeed rate (OF2) between the second feed roller and the winding roller is 1.6 to 1.8%. If it is less than 1.6%, the problem of unraveling due to excessive tension increases, increasing the probability of hair generation, and in conclusion, quality. It has the problem of reduced stability. In addition, if the overfeed rate exceeds 1.8%, quality uniformity deteriorates due to partial agglomeration during flammability, and partial flammability and decombustion defects occur.
그러므로 본 발명에 의하면, 리사이클 PET기반의 항균성이 우수하고 신축성 이 우수한 리사이클 폴리에스테르 복합가연가공사를 제공할 수 있다.Therefore, according to the present invention, it is possible to provide recycled polyester composite false twisted yarn with excellent antibacterial properties and excellent elasticity based on recycled PET.
