본 발명은 폴리에스테르 잠재권축필라멘트를 인터레이스를 행한 후 히터를 통과시키고 가연을 한 후 항균제액을 도포한 후 권취하여 일회용부직포 마스크에 사용되고 있는 나일론-스판덱스 마스크 끈을 대체할 수 있는 폴리에스테르 가공사를 제공하는 것이다.The present invention provides a polyester processed yarn that can replace the nylon-spandex mask string used in disposable nonwoven masks by interlacing a polyester latent crimped filament, passing it through a heater, applying an antibacterial solution, and then winding it up after performing false twist will do

근래에 들어 코로나19, 메르스, 사스등 병원성 바이러스의 전세계적인 대유행(pandemic)이 심각한 문제가 되고 있어 전염성 이에 대한 해결책이 적극적으로 요구되고 있다. In recent years, the global pandemic of pathogenic viruses such as Corona 19, MERS, and SARS has become a serious problem, and a solution to the contagiousness is actively required.

아직 바이러스에 대응하는 백신은 개발되지 못하고 있는 실정이며, 바이러스의 빠른 유전적 변이특성을 고려할 때 전염성 바이러스에 효과적으로 대응하는 방법은 바이러스의 전파를 차단하여 예방하는 방법이 최선이라고 할 수 있다.A vaccine against the virus has not yet been developed, and considering the rapid genetic mutation of the virus, it can be said that the best way to effectively respond to the infectious virus is to block the spread of the virus and prevent it.

바이러스의 주감염원인 비말을 차단하기 위한 수단으로서 개인 위생 마스크의 착용이 WHO를 비롯한 각국에서 권고 또는 의무사항이 되고 있으며, 국내에서는 일회용 마스크가 주로 사용되고 있으며, 1일 사용량이 1500만장에 이르러 사용후 마스크의 재활용문제 또한 심각한 문제로 대두되고 있다.Wearing a personal hygiene mask as a means to block droplet, the main source of infection of the virus, is recommended or mandatory in each country, including the WHO, and disposable masks are mainly used in Korea. Mask recycling is also a serious problem.

이러한 일회용마스크는 부직포로 이루어진 겉감, 안감, 필터, 귀걸이끈으로 구성되어 있으며, 겉감, 안감, 필터는 폴리프로필렌으로 이루어져 분리하여 재활용으로 분류하여 처리할 수 있다. These disposable masks are composed of an outer material, a lining, a filter, and an earring string made of a non-woven fabric, and the outer material, the lining, and the filter are made of polypropylene and can be separated and disposed of by recycling.

그러나 귀걸이끈은 신축성을 가진 끈으로서 현재는 나일론 DTY 140D/48F~72F 1가닥과 폴리우레탄 140D를 3배로 연신한 1가닥을 같이 투입해서 마스크 끈 제조장치를 사용해서 제조한 끈을 사용하여 겉감에 열융착하여 사용하고 있다. 이러한 현재의 마스크끈은 나일론과 폴리우레탄을 사용하고 있어서 재활용하기가 어렵고, 나일론과 폴리우레탄의 가격이 비싼 단점이 있다.However, earring straps are elastic straps. Currently, one strand of nylon DTY 140D/48F~72F and one strand of polyurethane 140D are added together, and a string manufactured using a mask string manufacturing device is used to put on the outer material. It is heat-sealed and used. These current mask straps are difficult to recycle because nylon and polyurethane are used, and the cost of nylon and polyurethane is high.

1)대한민국특허등록제10-2112218호(2020년05월19일 공고)1) Korea Patent Registration No. 10-2112218 (Notice on May 19, 2020)

그러므로 본 발명에서는 현재 일회용부직포 마스크에 사용되고 있는 나일론-스판덱스 마스크 끈을 대체할 수 있고 폴리우레탄을 사용하지 않는 신축성이 우수한 폴리에스테르 가공사를 제조하여 일회용 마스크 끈을 제공함으로써 사용시에는 기존의 나일론-스판덱스 마스크 끈과 동일하게 사용할 수 있으며, 재활용단계에서는 마스크 끈과 마스크 면을 분리하여 끈을 분리하여 재활용할 수 있는 마스크끈용 폴리에스테르 잠재권축가연사를 제공하는 것을 기술적과제로 한다.Therefore, in the present invention, it is possible to replace the nylon-spandex mask string currently used in disposable non-woven masks, and provides a disposable mask string by manufacturing a polyester processed yarn with excellent elasticity that does not use polyurethane. It can be used in the same way as the string, and in the recycling stage, the technical task is to provide a polyester latent crimped yarn for mask string that can be recycled by separating the mask string and the mask side and separating the string.

그러므로 본 발명에 의하면, 폴리에스테르 잠재권축필라멘트를 제1피드롤러로 공급하고 공기압은 0.5~1.5kg/㎠이고, 노즐직경은 1.2~2.0㎜인 인터레이스노즐에서 인터레이스한 후, 제2피드롤러를 거치고 온도가 100℃~140℃인 제1히터를 거치며 제1차열처리를 한 후, 가연유니트를 거치며 가연을 한 후, 제3피드롤러를 통과시키고, 항균제액부여장치를 통과시켜 상기 폴리에스테르 잠재권축필라멘트의 표면에 항균제액을 도포한 후, 사속 600~1000m/분으로 권취하는 것을 특징으로 하는 재활용이 가능한 마스크끈용 폴리에스테르 잠재권축가연사의 제조방법이 제공된다.Therefore, according to the present invention, the polyester latent crimped filament is supplied to the first feed roller, the air pressure is 0.5 to 1.5 kg/cm2, and the nozzle diameter is 1.2 to 2.0 mm after interlacing in the interlaced nozzle, and then through the second feed roller, After first heat treatment through a first heater with a temperature of 100°C to 140°C, false-twisting through a false twisting unit, passing through a third feed roller, and passing through an antibacterial liquid imparting device to crimp the polyester latent After applying the antibacterial solution to the surface of the filament, there is provided a method for manufacturing a recyclable polyester latent crimp false twisted yarn for a mask string, characterized in that the winding at a yarn speed of 600 ~ 1000m / min.

이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.

본 발명의 재활용이 가능한 마스크끈용 폴리에스테르 잠재권축가연사의 제조방법은 폴리에스테르 잠재권축필라멘트를 인터레이스하고, 열처리를 한 후, 가연을 행하고, 항균제액을 도포한 후 권취하는 것이다.The method for manufacturing a recyclable polyester latent crimped false twisted yarn for a mask string of the present invention is to interlace polyester latent crimped filaments, perform heat treatment, perform false twisting, apply an antibacterial agent solution, and then wind the yarn.

본 발명의 재활용이 가능한 마스크끈용 폴리에스테르 잠재권축가연사의 제조방법은 도 1에 도시된 바와 같이 폴리에스테르 잠재권축필라멘트(1)를 제1피드롤러(2)로 공급하고 공기압은 0.5~1.5kg/㎠이고, 노즐직경은 1.2~2.0㎜인 인터레이스노즐(3)에서 인터레이스한 후, 제2피드롤러(4)를 거치고 온도가 100℃~140℃인 제1히터(5)를 거치며 제1차열처리를 한 후, 가연유니트(6)를 거치며 가연을 한 후, 제3피드롤러(7)를 통과시키고, 항균제액부여장치(8)를 통과시켜 상기 폴리에스테르 잠재권축필라멘트의 표면에 항균제액을 도포한 후, 권취롤러(9)로 사속 600~1000m/분으로 권취한다.In the method for manufacturing the recyclable polyester latent crimped false twisted yarn for mask string of the present invention, as shown in FIG. 1 , the polyester latent crimped filament 1 is supplied to the first feed roller 2 and the air pressure is 0.5 to 1.5 kg. After interlacing in interlaced nozzles 3 with a /cm2 nozzle diameter of 1.2 to 2.0 mm, through a second feed roller 4 and through a first heater 5 having a temperature of 100° C. to 140° C. After heat treatment, after false twisting through the false twisting unit 6, the third feed roller 7 passes, and the antibacterial agent liquid applying device 8 passes through the antibacterial agent solution on the surface of the polyester latent crimped filament. After coating, it is wound with a winding roller 9 at a yarn speed of 600 to 1000 m/min.

본 발명에서 원사로 사용하는 폴리에스테르 잠재권축필라멘트(1)는 물성이 상이한 이종의 폴리에스테르 폴리머를 동일한 구금에서 용융방사하여 한 올의 섬유가닥에 2종류의 물성이 상이한 폴리머가 붙어있는 형태의 원사로서 이러한 잠재권축필라멘트는 외부에서 가해지는 스트레스(열, 연신 등)에 의해서 신축성이 잘 발현되는 특징을 갖고 있다.The polyester latent crimped filament (1) used as the yarn in the present invention is a type of yarn in which two types of polymers with different properties are attached to one fiber strand by melt-spinning different types of polyester polymers with different properties in the same spinneret. As such, these latent crimped filaments have the characteristic of being well expressed by external stresses (heat, elongation, etc.).

이러한 잠재권축필라멘트는 연신을 통해 수축률을 증대시킨 원사로서 수축률은 우수하나, 물성 차이가 나는 이성분 폴리에스테르로 이루어진 잠재권축필라멘트를 연신하게 되면 연신에 의한 배향성의 증대로 일반적인 가연공정(가연→열처리→해연)을 거치더라도 벌키성을 부여하기 어렵다.These latent crimped filaments are yarns with increased shrinkage through stretching, and although the shrinkage rate is excellent, when a latent crimped filament made of a bicomponent polyester with a difference in physical properties is drawn, the general false twisting process (false twisting → heat treatment) → Haeyeon), it is difficult to give bulkiness.

이렇게 본 발명에서는 통상적으로 가연가공이 잘되지 않는 폴리에스테르 잠재권축필라멘트를 가연가공하여 신축성이 우수하고 항균성이 있는 잠재권축가연사를 제조하는 것이다.In this way, in the present invention, a latent crimped false twisted yarn having excellent elasticity and antibacterial properties is manufactured by false twisting a polyester latent crimped filament, which is generally not good in false twisting.

본 발명에서는 폴리에스테르 잠재권축필라멘트(1)를 제1피드롤러(2)로 공급하고 공기압은 0.5~1.5kg/㎠이고, 노즐직경은 1.2~2.0㎜인 인터레이스노즐(3)에서 인터레이스한 후, 제2피드롤러(4)를 거치고 온도가 100℃~140℃인 제1히터(5)를 거치며 제1차열처리를 한 후, 벨트타입의 가연유니트(6)를 거치며 가연을 행하게 된다. In the present invention, the polyester latent crimped filament (1) is supplied to the first feed roller (2), the air pressure is 0.5 to 1.5 kg/cm2, and the nozzle diameter is 1.2 to 2.0 mm After interlacing in the interlaced nozzle (3), After passing through the second feed roller 4 and the first heater 5 having a temperature of 100° C. to 140° C., the first heat treatment is performed, and then false twisting is performed through the belt-type false twisting unit 6 .

상기 인터레이스시 공기압력 0.5㎏/㎠미만에서는 가공사의 집합성이 미흡한 문제점이 발생할 수 있고, 1.5㎏/㎠초과시에는 루프가 다량 발생하여 후공정에서의 작업성이 떨어지는 문제점이 발생할 수 있다. 열처리시 온도는 100℃~140℃인 것이 바람직한데, 히터온도 100℃미만에서는 가연이 되지 않아 벌키성이 생기지 않는 문제점이 발생하며, 140℃초과시에는 필라멘트가 융착되는 문제점이 발생할 수 있다.When the interlacing air pressure is less than 0.5 kg/cm 2 , a problem of insufficient assembly of the processed yarn may occur, and when it exceeds 1.5 kg/cm 2 , a large amount of loops may occur, which may cause a problem in that workability in the post-process is deteriorated. It is preferable that the temperature during heat treatment is 100° C. to 140° C., but when the heater temperature is less than 100° C., it is not combustible, so there is a problem that bulkiness does not occur.

일반적인 가연의 경우 가연비가 1.5∼2.5가 되도록 설정하나, 본 발명의 경우에는 가연비(VR) 1.0~1.2이 되도록 설정하여 잠재권축필라멘트에 전단스트레스를 부여하여 폴리에스테르 잠재권축필라멘트로서는 벌키성 및 신축성을 우수하게 하는데 효과적이다.In the case of general false twisting, the combustibility ratio is set to be 1.5 to 2.5, but in the present invention, the combustibility ratio (VR) is set to 1.0 to 1.2, and shear stress is applied to the latent crimped filament to provide bulkiness and elasticity as a polyester latent crimped filament. effective in improving

상기 가연후 항균제액부여장치(6)를 통과시켜 상기 폴리에스테르 잠재권축필라멘트의 표면에 항균제액을 도포하는데, 상기 항균제액부여장치(6)는 합성섬유의 방사시 사용하는 공지의 유제부여장치를 사용할 수 있다. 상기 항균제액은 키토산계 항균제, 은나노계 항균제 및 무기계 항균제 중 어느 하나 이상의 항균제 5~10중량% 및 잔부로서 순수로 이루어진 항균제액이 바람직하다.After the false twist, the antibacterial agent solution is passed through the antibacterial agent liquid applying device 6 to apply the antibacterial agent solution to the surface of the polyester latent crimped filament. Can be used. The antibacterial solution is preferably an antibacterial solution composed of 5 to 10% by weight of any one or more antibacterial agents of chitosan-based antibacterial agent, silver nano-based antibacterial agent, and inorganic antibacterial agent, and pure water as the balance.

상기 제1피드롤러와 제2피드롤러간의 오버피드율은 1.002~1.05인 것이 바람직한데, 오버피드율 1.002미만에서는 사절, 능락, 이고 등 권취 패키지 형태 이상의 문제점이 발생되며, 1.05를 초과하는 경우에는 해사불량, 권취 패키지가 과도하게 커지는 문제점이 발생할 수 있다. 제2피드롤러와 제3피드롤러간의 연신비율은 1.03~1.07배인 것이 바람직한데, 연신비율 1.03배미만에서는 잔류신도가 높아서 후속공정에서 의도하지 않는 연신이 발생되는 문제점이 발생되며, 연신비율 1.07배를 초과하는 경우에는 모우발생율 및 사절율이 높아져 가연작업성이 떨어지는 문제점이 발생할 수 있다.It is preferable that the overfeed rate between the first feed roller and the second feed roller is 1.002 to 1.05. If the overfeed rate is less than 1.002, problems such as thread trimming, crochet, and sagging occur, and if it exceeds 1.05, There may be a problem in that the maritime defect and the winding package become excessively large. It is preferable that the draw ratio between the second feed roller and the third feed roller is 1.03 to 1.07 times, but if the draw ratio is less than 1.03 times, the residual elongation is high and there is a problem that unintended drawing occurs in the subsequent process, and the draw ratio is 1.07 times In the case of exceeding this, the hair generation rate and the thread trimming rate increase, which may cause a problem in that the flammability workability is deteriorated.

이렇게 제조된 본 발명의 상기 폴리에스테르 잠재권축가연사를 사용하여 공지의 마스크끈제조기를 사용하여 재활용이 가능한 마스크끈을 제조하여 마스크 겉감의 일정부분에 열융착시켜 일회용마스크를 제작하는데 사용된다.Using the polyester latent crimped false twisted yarn of the present invention prepared in this way, a reusable mask string is manufactured using a known mask string maker, and heat-sealed to a certain part of the mask outer material is used to manufacture a disposable mask.

그러므로 본 발명에 의하면, 일회용부직포 마스크에 사용되고 있는 마스크 끈의 원사인 나일론-스판덱스사를 대체할 수 있는 폴리에스테르 가공사를 제공하여 마스크끈을 제조하는데 사용함으로써 마스크사용시에는 기존의 나일론-스판덱스 마스크 끈과 동일하게 사용할 수 있으며, 재활용단계에서는 마스크 끈과 마스크 면을 분리하여 끈을 분리하여 재활용할 수 있다.Therefore, according to the present invention, by providing a polyester processed yarn that can replace the nylon-spandex yarn, which is the yarn of the mask string used in the disposable nonwoven mask, and using it to manufacture the mask string, when using the mask, the existing nylon-spandex mask string and It can be used in the same way, and in the recycling step, the mask string and the mask side are separated, and the string can be separated and recycled.

도 1은 본 발명의 마스크끈용 폴리에스테르 잠재권축가연사의 제조공정의 모식도이다. 1 is a schematic diagram of the manufacturing process of the polyester latent crimp false twisted yarn for the mask string of the present invention.

다음의 실시예에서는 본 발명의 재활용이 가능한 마스크끈용 폴리에스테르 잠재권축가연사를 제조하는 비한정적인 예시를 하고 있다.The following examples give a non-limiting example of manufacturing the polyester latent crimp false twisted yarn for a mask string that can be recycled according to the present invention.
