Description
본 발명은 폴리에스테르계 가공사의 제조방법에 관한 것으로서 보다 구체적으로는 이종섬도의 필라멘트를 동시에 방사할 수 있는 태세형태의 방사구금을 통해 직접방사한 이종섬도의 폴리에스테르계 필라멘트를 가연가공하여 세섬도 필라멘트 부분을 물리적인 힘으로 강제적으로 절단시킴으로써 방적사와 같은 외관효과를 가지도록 한 것이다.The present invention relates to a method for producing a polyester-based processed yarn, and more specifically, to a method for producing a polyester-based processed yarn by twisting polyester-based filaments of different fineness directly spun through a spinning type spinning- The filament portion is forcibly cut by a physical force so as to have the same appearance effect as a spun yarn.
합성섬유 필라멘트는 고유의 물성 때문에 여러분야의 용도로 활용되어 왔으나 고유의 광택이나 외관으로 인해 방적사와 같은 감촉을 나타내기는 어려웠던 실정이었다.Synthetic fiber filaments have been used for various purposes due to their inherent physical properties, but it was difficult to show the same feeling as a spun yarn due to inherent gloss and appearance.
이에 섬유가공업계에서는 여러 가지 방안을 모색하여 방적사와 같은 촉감을 가지는 가공사의 제조를 시도하였다. 복합가연기에서 모우를 발생시키는 찰과장치를 사용하여 모우를 발현시키는 제조기술이 개발되었으나, 찰과장치에 의한 사절성 및 모우발생의 균일성이 좋지 못한 문제가 있었다. In the textile industry, various methods were searched in the field of engineering to manufacture a processed yarn having the same feel as a spun yarn. A manufacturing technique for developing mow by using a scratching device that generates mowing in a multifunctional smoke has been developed. However, there has been a problem that the uniformity of mowing and mowing by the scratching device is poor.
또한, 물성이 상이한 2종의 원사를 공기교락처리 후 연신 및 가연하여 방적 사(Spun Yarn)를 제조하는 기술이 있었으며, 복굴절율이 0.04~0.07 사이의 폴리에틸렌테레프탈레이트(이하 PET라 한다.) 반연신사와 복굴절율이 0.12~0.16사이의 PET 연신사를 공급롤러 전에 합사하여 공기교락처리한 다음, 2종의 원사를 최고 연신배율 차에 의해 연신 및 가연하면 복굴절률이 높은 연신사는 절단하여 모우가 발현되고, 복굴절율이 낮은 반연신사는 가연사 형태에 의한 모우 형성하는 기술이 시도되기도 했다.Further, there has been a technique for producing a spun yarn by stretching and twisting two types of yarns having different physical properties after air entanglement treatment, and there is a technique of producing polyethylene terephthalate (hereinafter, referred to as PET) having a birefringence of 0.04 to 0.07 When a stretched PET yarn having a blend ratio of 0.12 to 0.16 and a birefringence of 0.12 to 0.16 is bundled and air-entangled before the feed roller, and then the two types of yarns are stretched and twisted by the difference in maximum draw ratio, And a technique of forming a moth with a twisted yarn shape has been attempted in a semi-shrine having a low birefringence.
또한, 복굴절율이 0.04인 PET 반연신사와 복굴절율이 0.028인 PET 반연신사를 합사하여 공기교락처리하여 복굴절율이 낮은 0.028 PET 반연신사가 절단되어 모우가 발현되도록 하는 방법과 복굴절률이 0.04인 반연신사와 복굴절율이 0.156인 연신사를 합사하여 공기교락처리 함으로서 연신사가 절단되어 모우가 발현되도록 하는 방법이 소개되고 있으나, 상기 선행기술은 작업성이 불량하고 특히 생산속도가 120m/min정도로서 생산성이 아주 낮은 문제점이 있었다. 또한, 복굴절율이 서로 다른 소재를 각각 방사한 후, 가연단계에서 모우를 형성시키는 제조기술의 경우 2종의 원사를 제조한 다음 복합가연에 의하였기 때문에 공정loss가 높았고 모우발현이 균일하지 못한 문제점이 있었으며 생산속도 저하 등의 문제점을 안고 있었다. In addition, a PET yarn with a birefringence of 0.04 and a PET yarn with a birefringence of 0.028 are folded together and subjected to air entangling treatment to cut the 0.028 PET yarn with low birefringence, A method is disclosed in which a stretched yarn is cut to produce a moult by means of air entanglement with a gentle yarn and a twist yarn having a birefringence of 0.156. However, the prior art has a problem in that workability is poor and production speed is about 120 m / min There was a very low issue. Further, in the case of a manufacturing technique in which a material is formed in the false twisting step after each material having a different birefringence index is radiated, two kinds of yarns are produced, and then the composite loss is caused by the composite false twist, so that the process loss is high and mow expression is not uniform And there was a problem such as a decrease in production speed.
그러므로 본 발명에 의하면 태세형태를 가진 방사구금 제작 및 복합방사기술을 이용하여 섬도차이가 나는 1종의 이종섬도의 필라멘트를 제조한 다음, 사가공 기술을 이용하여 섬도가 낮은 부분을 물리적으로 절단시킴으로써 균일한 모우발현 을 통해 방적사와 같은 촉감과 합섬의 쾌적기능을 가지는 폴리에스테르계 가공사를 높은 공정효율로 제조하는 것을 기술적 과제로 한다. Therefore, according to the present invention, one kind of filament having different fineness is manufactured by using a spinneret manufacturing method and a composite spinning technique having a posture type, and then the filament having a low fineness is physically cut It is a technical task to manufacture a polyester-based processed yarn having a comfortable function of a tactile and synthetic fiber like a spun yarn with a high process efficiency through uniform mow expression.
본 발명에 의하면 이종섬도의 필라멘트를 동시에 방사할 수 있는 태세형태의 방사구금을 통해 방사속도 3,800~4,000m/분으로 직접방사하고 연신비를 2.8~3.2, 열고정 온도를 110~130℃로 하여 연신 및 열고정하여 이종섬도의 폴리에스테르계 필라멘트를 제조한 후, 상기 이종섬도의 폴리에스테르계 필라멘트로 사가공 속도 350~450m/min로 마찰 가연기를 통과시킨 후, 연신비 1.05~1.10으로 연신하고, 사속비(V/R) 1.3~1.4로 조정한 후, 히터온도 160~180℃로 열처리 한 후, 에어압력 2~3bar의 조건으로 인터레이스하는 것을 특징으로 하는 방적사효과를 가지는 폴리에스테르계 가공사의 제조방법이 제공된다.According to the present invention, the yarn is directly radiated at a spinning speed of 3,800 to 4,000 m / min through a spinning spinneret capable of spinning filaments of different fineness at the same time, stretched at a stretching ratio of 2.8 to 3.2, And the polyester filaments having different finenesses were prepared and passed through a friction stirrer at a working speed of 350 to 450 m / min to the polyester filaments of different fineness, followed by drawing at a draw ratio of 1.05 to 1.10, (V / R) of 1.3 to 1.4, heat-treated at a heater temperature of 160 to 180 占 폚, and then interlaced at an air pressure of 2 to 3 bar. The process for producing a polyester- / RTI >
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 폴리에스테르계 가공사의 제조방법은 이종섬도의 필라멘트를 동시에 방사할 수 있는 태세형태의 방사구금을 통해 직접방사하고 연신 및 열고정하여 만든 이종섬도의 폴리에스테르계 필라멘트를 마찰 가연기에 통과시킨 후, 연신하고, 열처리 한 후, 인터레이스하여 세섬도 필라멘트 부분을 물리적인 힘으로 강제적으로 절단시킴으로써 방적사와 같은 외관효과를 가지도록 한 것이다.The method for producing a polyester-based processed yarn of the present invention comprises spinning a polyester-based filament of different fineness, which is directly spinnable through a spinning type spinning nozzle capable of simultaneously spinning filaments of different fineness, Stretched, heat-treated, interlaced, and forcedly cut off the three-filament filaments by a physical force so as to have the same appearance effect as a spun yarn.
본 발명의 폴리에스테르계 가공사를 제조하기 위해 사용되는 이종섬도의 폴리에스테르계 필라멘트는 하나의 방사구금을 통해 동시에 방사되는 태세섬도의 폴 리에스테르계 필라멘트이다. The polyester filaments of different fineness used for producing the polyester-based processed yarns of the present invention are polyester filament yarns having a fine filament size that are simultaneously radiated through one spinneret.
이러한 이종섬도의 폴리에스테르계 필라멘트를 방사하기 위한 태세형태의 방사구금의 특성은 다음과 같다. 도 4에 도시된 방사구금(100)은 코어(10)부분과 시쓰(20)부분으로 나뉘어 지며, 코어(Core)부분은 8~12 홀을 가지고 시쓰(Sheath)부분은 40~48홀을 가지며, 코어부분의 개개의 홀직경보다 시쓰부분의 개개의 홀직경이 4~6배 큰 것이 바람직한데, 코어와 시쓰의 홀직경을 4~6배 정도 차이를 줌으로써 후의 마찰 가연단계에서의 마찰에 의해 시쓰부분의 세섬도 필라멘트가 원활하게 잘 끊어질 수 있도록 할 수 있다. 구금 사이즈가 6배를 초과하면 방사성이 좋지 못하여 원사제조가 불가능하고, 4배보다 적으면 마찰 가연후에 모우발현이 잘 발현되지 못하는 문제점이 있다.The characteristics of the spinning type spinning type for spinning the polyester filaments having different degrees of fineness are as follows. The spinneret 100 shown in FIG. 4 is divided into a
방사속도(m/min)는 3500~4000m/min, 방사온도(℃)는 290~295℃정도가 바람직하며, 제1고뎃롤러(GR1)와 제2고뎃롤러(GR2)의 연신비(GR2/GR1)는 2.8~3.5로 설정하였다. 여기서, 제1고뎃롤러의 속도는 1100~1500 m/min 정도가 좋으며, 1500m/min을 초과하였을 때에는 단사절 발생으로 방사성이 좋지 못한 문제점이 있다. 제2고뎃롤러의 열고정온도는 110~130℃ 조건으로 하고 권취하여 이종섬도의 폴리에스테르계 필라멘트를 얻는다.It is preferable that the spinning speed (m / min) is in the range of 3500 to 4000 m / min and the spinning temperature (캜) is in the range of 290 to 295 캜. The stretching ratio GR2 / GR1 of the first godet roller GR1 and the second godet roller GR2 ) Was set to 2.8 to 3.5. Here, the speed of the first godet roller is preferably about 1100 to 1500 m / min, and when the speed is higher than 1500 m / min, there is a problem that radioactivity is poor due to occurrence of a single thread. The heat setting temperature of the second godet roller is set at 110 to 130 ° C and taken up to obtain a polyester filament of different fineness.
이렇게 동시방사되는 상기 이종섬도의 폴리에스테르계 필라멘트는 세섬도 폴리에스테르계 필라멘트의 섬도가 0.4~1.25데니아, 태섬도 폴리에스테르계 필라멘트가 2.5~7.5데니아의 범위를 갖는 것이 바람직한데, 특히 상기 태섬도 폴리에스테르계 필라멘트의 섬도는 세섬도 폴리에스테르계 필라멘트의 섬도의 4~6배인 것이 마 찰 가연후에 모우발현을 잘 할 수 있다.The polyester filaments of the different fineness simultaneously radiated in this way preferably have a fineness of 0.4 to 1.25 denier of the polyester filaments of three filaments and a filament of 2.5 to 7.5 denier of the filaments of the filament filaments, The fineness of the polyester-based filament is 4 to 6 times that of the fineness of the polyester-based filament of the three filaments, and the filament can be well expressed after the warping.
이렇게 얻은 이종섬도의 폴리에스테르계 필라멘트를 마찰 가연기에 공급하여여 사가공 사속 350~450m/min으로 가연한 후, 연신비 1.05~1.10으로 연신하고, 사속비(V/R) 1.3~1.4로 조정한 후, 히터온도 160~180℃로 열처리 한 후, 에어압력 2~3bar의 조건으로 인터레이스하여 후공정인 제직공정에서의 제직성이 우수하고, 방적사와 유사한 형태를 가질 수 있는 폴리에스테르계 가공사를 제조한다.The polyester filament thus obtained was fed to a friction stirrer and twisted at 350 to 450 m / min in a drawing machine, followed by stretching at a draw ratio of 1.05 to 1.10, and adjusted to have a step ratio (V / R) of 1.3 to 1.4 After heat treatment at a heater temperature of 160 to 180 ° C, interlaced at an air pressure of 2 to 3 bar to produce a polyester-based processed yarn excellent in warpability in a post-process weaving process and having a shape similar to a spun yarn do.
이종섬도의 폴리에스테르계 필라멘트의 세섬도 필라멘트 부분은 가연가공공정에서 물리적인 힘으로 강제적으로 절단되고, 인터레이스 공정에 의해 절단된 필라멘트가 균일하게 집속되어 최종제품인 폴리에스테르계 가공사에 균일한 모우발현을 통해 외관이 방적사와 같은 외관효과를 가지도록 할 수 있는 것이다.The three filament filament portions of the polyester filaments of different fineness are forcibly cut by the physical force in the torning process and the filaments cut by the interlacing process are uniformly focused to uniformly spread the filaments to the final product, So that the appearance can be made to have the same appearance effect as that of the spun yarn.
사속비가 너무 낮으면 폴리에스테르계 가공사가 방적사와 유사한 형태를 나타낼 수 있으나 제직공정에서 해사성이 매우 좋지 못한 문제점이 있었으며, 연신비가 1.10 초과시에서는 가연 작업성이 좋지 못하고 강도가 저하되는 현상을 보였고, 1.05 미만에서는 방적사 형태를 형성하는 것이 어려운 문제점이 있었다. 그리고, 인터레이스시 에어압력이 3bar보다 높을 경우에는 직물 제직후에 인터레이스 자국이 원단상에 나타나 원단 품위를 저하시킬 수 있으며, 2bar보다 낮을 경우에는 해사성이 약간 떨어지는 문제점을 가진다. If the ratio is too low, the polyester-based processing yarn may exhibit a shape similar to that of the spun yarn, but the marine property is not very good in the weaving process. When the stretching ratio is more than 1.10, the flammability is poor and the strength is decreased. If it is less than 1.05, it is difficult to form a spun yarn form. If the air pressure during interlacing is higher than 3 bar, the interlacing mark may appear on the distal end of the fabric immediately after the fabric, and the quality of the fabric may be lowered. If the air pressure is lower than 2 bar, the marginality is slightly lowered.
이렇게 제조된 폴리에스테르계 가공사를 이용하여 연사를 400TPM 정도를 주고 경위사로 제직 및 염색가공된 원단의 촉감은 면과 같이 부드러운 촉감을 가져 기존의 폴리에스테르계 가연가공사를 이용하여, 동일한 연사, 제직, 염색가공된 원 단보다 부드러운 촉감특성을 가진다. Using the polyester fabric thus manufactured, the yarn is weighed at about 400 TPM, and the feel of the fabric that has been woven and dyed with the warp yarn has a soft feel like cotton, and the same polyester yarn, It has more soft touch than dyed fabric.
그러므로 본 발명에 의하여 제조된 폴리에스테르계 가공사는 시쓰부분의 세섬도 폴리에스테르계 필라멘트가 일부분 절단되어 마치 방적사의 외관을 가질 수 있게 되어 후의 제직이나 편직에 의한 직편물 제조시 부드러운 촉감을 부여할 수 있는 한편 폴리에스테르 고유의 물성을 잘 반영할 수 있는 효과를 가진다.Therefore, the polyester-based processing yarn produced by the present invention can be partially cut into three filament polyester filaments of the sheath portion so as to have the appearance of a yarn-like yarn, so that a soft touch can be imparted to the subsequent weaving or knitting While it has the effect of reflecting the inherent physical properties of the polyester.
이하 다음의 실시 예에서는 본 발명의 방적사효과를 가지는 폴리에스테르계 가공사의 제조방법에 대한 비한정적인 예시를 하고 있다.The following examples illustrate non-limiting examples of the process for producing the polyester-based processed yarn having the yarn-spun yarn effect of the present invention.
