본 발명은 신축성 폴리에스테르 복합사의 제조방법 및 그로부터 제조된 신축성 폴리에스테르 복합사에 관한 것으로서, 더욱 상세하게는 천연의 질감과 색감 구현이 가능한 개질 폴리에스테르 섬유를 초사로 사용하고, 신축성을 발현하는 폴리에스테르계 잠재권축사를 심사로 사용하여 복합연신 후, 공기교락하는 신축성 폴리에스테르 복합사의 제조방법 및 그로부터 제조된 혼섬도 및 염색성이 우수할 뿐 아니라, 신축회복성이 우수한 신축성 폴리에스테르 복합사에 관한 것이다.The present invention relates to a method for producing a stretchable polyester composite yarn and a stretchable polyester composite yarn manufactured therefrom, and more specifically, using a modified polyester fiber capable of realizing natural texture and color as a superfiber, and expressing elasticity A method for preparing a stretchable polyester composite yarn which is interlaced after using an ester-based latent yarn as a screening, and an excellent blendability and dyeing property prepared therefrom, as well as a stretchable polyester composite yarn having excellent stretch recovery properties will be.
종래의 폴리에스테르 복합사는 부분배향사인 반연신사(Partially Oriented Yarn, POY)와 연신사(Flat Yarn, FY)를 서로 공기교락하여 제조함으로써, 두 소재원사간의 열수축차에 의한 스펀(Spun) 복합가공사를 제조하는 방법이 널리 사용되고 있다.Conventional polyester composite yarns are manufactured by interlacing partially oriented yarns (Partially Oriented Yarn, POY) and stretched yarns (Flat Yarn, FY) to each other, thereby producing spun composite processing by heat shrinkage between two material yarns. Manufacturing methods are widely used.
또한, 폴리에스테르 복합사의 독특한 표면효과를 위하여, 초부(sheath)에 무기입자를 다량 함유시켜 제조된 폴리에스테르 섬유를 사용하거나, 아세테이트, 레이온 등의 천연섬유를 사용하여 복합사를 제조하는 방법이 공지된 바 있다.In addition, for the unique surface effect of the polyester composite yarn, a method for producing a composite yarn using polyester fibers prepared by containing a large amount of inorganic particles in the sheath, or using natural fibers such as acetate and rayon are known. It has been.
그의 일례로서, 대한민국 공개특허공보 제2001-0063955호에서는 섬도가 50∼100데니어인 아세테이트사와 폴리에스테르 불균일 연신사를 공기교락시켜서 제조한 폴리에스테르/아세테이트 복합사를 개시하고 있다. 즉, 상기 발명의 복합사는 초사로서 천연섬유인 아세테이트를 사용하고, 심부의 소재원사로서 통상의 폴리에스테르 섬유를 사용하는 것이나, 초사로서 천연섬유인 아세테이트 소재를 사용하므로, 원료의 수급에 대한 문제점, 경제성 문제, 합성섬유인 폴리에스테르계 섬유와의 혼섬도, 심초사간의 염색 불균일 등의 문제가 발생한다. 또한, 상기 복합사에는 신축성을 기대할 수 없다.As an example, Korean Patent Laid-Open Publication No. 2001-0063955 discloses a polyester / acetate composite yarn produced by air-entering an acetate yarn having a fineness of 50 to 100 denier and a polyester non-uniformly stretched yarn. That is, the composite yarn of the present invention uses acetate as a natural fiber as a yarn, and ordinary polyester fiber as a raw material yarn in the core, or uses a acetate material as a natural fiber as a yarn, and thus, problems in supply and demand of raw materials, Problems such as economical problems, interweaving with polyester-based fibers, which are synthetic fibers, and dyeing unevenness between myocardial yarns occur. In addition, elasticity cannot be expected in the composite yarn.
또한, 대한민국 특허공개공보 제2006-78217호, 일본국 특개평 제1025636호 및 일본국 특개평 제11181643호에는 폴리아미드계 복합사의 제조방법에 대하여 개시하고 있다. 그중에서도, 대한민국 특허공개 제2006-78217호는 두 종류의 원사로 제조되는 복합가연사의 제조방법에 관한 것으로서, 상세하게는 심사로서 원착 나일론 FDY(Fully Drawn Yarn)을 사용하고, 초사로는 이형단면의 나일론 POY(Partially Oriented Yarn)를 사용함으로써, 원착나일론으로 인한 천연섬유와 같은 자연스러운 외관과 이형단면의 나일론으로 인한 흡한속건성과 소프트감이 우수한 복합가연사를 제공한다고 기술하고 있다. 그러나, 상기 방법에는 벌키성과 터치성은 우수하나, 합성섬유 사용에 따른 천연의 느낌이나 발색성을 기대할 수 없다.In addition, Korean Patent Publication No. 2006-78217, Japanese Patent Laid-Open No. 1025636, and Japanese Patent Laid-Open No. 11181643 disclose a method for producing a polyamide composite yarn. Among them, Korean Patent Laid-Open Publication No. 2006-78217 relates to a method of manufacturing a composite twisted yarn made of two kinds of yarns, and in particular, a fused nylon FDY (Fully Drawn Yarn) is used as the screening, By using nylon POY (Partially Oriented Yarn), it provides composite twisted yarn with excellent absorption and quick drying and softness due to nylon in its shape and natural appearance such as natural fiber due to native nylon. However, the method is excellent in bulkiness and touch, but can not expect the natural feeling or color development according to the use of synthetic fibers.
더욱이, 종래의 폴리에스테르 복합사는 이수축 혼섬사로서의 벌키한 특성은 발현가능하나, 신축성 직물을 제조하기 위한 충분한 스트레치성을 발현하기에는 불가능하 다.Moreover, conventional polyester composite yarns are capable of expressing bulky properties as bi-shrink blended yarns, but not capable of expressing sufficient stretch to produce stretch fabrics.
이에, 본 발명자들은 폴리에스테르 복합사에 요구되는 전반적인 물성을 충족하는 폴리에스테르 복합사를 얻고자 노력한 결과, 천연의 질감과 색감 구현이 가능한 개질 폴리에스테르 섬유를 초사로 사용하고, 신축성을 발현하는 폴리트리메틸렌테레프탈레이트(이하, "PTT"이라 한다) 성분과 폴리에틸렌테레프탈레이트(이하, "PET"라 한다) 성분으로 이루어진 잠재권축사를 심사로 사용하여 복합연신 후, 공기교락하여 신축성이 우수한 고기능성 신축성 폴리에스테르 복합사를 제조하고, 상기 폴리에스테르 복합사가 강도 및 신도가 우수하고, 혼섬도 및 염색성이 우수할 뿐 아니라, 특히 신축회복성이 종래의 폴리에스테르 복합사보다 우수함을 확인함으로써, 본 발명을 완성하였다.Accordingly, the present inventors endeavored to obtain a polyester composite yarn that satisfies the overall physical properties required for the polyester composite yarn, using modified polyester fibers capable of realizing natural texture and color as a super yarn, and expressing elasticity High performance with excellent elasticity by interlacing with air after use of latent crimping yarn composed of trimethylene terephthalate (hereinafter referred to as "PTT") component and polyethylene terephthalate (hereinafter referred to as "PET") as a screening The present invention is prepared by producing a flexible polyester composite yarn, and confirmed that the polyester composite yarn is excellent in strength and elongation, excellent intermixability and dyeing properties, in particular stretch recovery is superior to conventional polyester composite yarn, Was completed.
본 발명의 목적은 유기 술폰산염계 개질제로 개질된 폴리에스테르 원사를 초사로 하고, 잠재권축사를 심사로 복합연신 후, 공기교락하여 제조되는 신축성 폴리에스테르 복합사의 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing a stretchable polyester composite yarn prepared by blending polyester yarns modified with an organic sulfonate-based modifier with latent yarns, followed by a composite drawing by screening the latent wound yarn.

이하, 본 발명을 상세히 설명하고자 한다.Hereinafter, the present invention will be described in detail.
본 발명은 신축성 폴리에스테르 복합사의 제조방법을 제공한다. 보다 상세하게는,The present invention provides a method for producing a stretchable polyester composite yarn. More specifically,
1) 고분자의 중합과정에서, 유기 술폰산염계 개질제 3 내지 10 중량%가 첨가되어 제조된 폴리에스테르 중합체를 2000∼2500mpm 방사속도로 방사하여 미연신사를 제조하고,1) In the polymerization process of the polymer, 3 to 10% by weight of the organic sulfonate-based modifier is added to spin the polyester polymer prepared at 2000 to 2500mpm spinning speed to prepare an undrawn yarn,
2) 고유점도 0.90∼1.20dl/g인 PTT 성분과 고유점도 0.40∼0.60dl/g인 PET 성분이 40:60 ∼ 60:40의 비율로 복합방사하여 제조된 잠재권축사를 2400∼2700mpm 방사속도로 방사하여 미연신사를 제조하고,2) 2400 ~ 2700mpm spinning speed of latent yarns produced by composite spinning of PTT component with intrinsic viscosity 0.90 ~ 1.20dl / g and PET component with intrinsic viscosity 0.40 ~ 0.60dl / g at a ratio of 40:60 to 60:40 Unstretched yarn is produced by spinning
3) 상기 단계 1)의 미연신사를 초사로 하고, 단계 2)의 미연신사를 심사로 하여, 상기 심사 및 초사간의 중량비를 30 내지 40 : 70 내지 60의 비율로 복합연신 후, 공기교락하는 것으로 이루어진 신축성 폴리에스테르 복합사의 제조방법을 제공한다.3) The non-drawn yarn of step 1) is used as the yarn, and the non-drawn yarn of step 2) is used as the screening, and the weight ratio between the screening and the super yarn is mixed at a ratio of 30 to 40:70 to 60. It provides a method for producing a stretched polyester composite yarn made.
단계 1)은 고분자의 중합과정에서, 유기 술폰산염계 개질제 1 내지 5 중량%를 첨가하여 개질 폴리에스테르 중합체를 제조하고, 2000∼2500mpm 방사속도로 방사하여 미연신사를 제조하여, 본 발명의 폴리에스테르 복합사의 초사성분으로 준비한다.Step 1) in the polymerization process of the polymer, by adding 1 to 5% by weight of an organic sulfonate-based modifier to prepare a modified polyester polymer, spinning at 2000 to 2500mpm spinning speed to produce an undrawn yarn, polyester composite of the present invention Prepared with the super yarn component of yarn.
즉, 본 발명의 폴리에스테르 복합사에 있어서, 상기 초사성분은 상기 개질 폴리에스테르 중합체가 알칼리 감량공정을 통하여 원사에 포함된 유기 술폰산염계 개질제 성분이 용해되면서 원사 표면에 섬유축 방향으로 자연스러운 요철효과가 발현되며(도 3), 이러한 원사 표면효과로 인하여 천연의 질감과 색감을 구현할 수 있다.That is, in the polyester composite yarn of the present invention, the superfiber component has a natural uneven effect in the fiber axis direction on the surface of the yarn while the modified polyester polymer is dissolved in the organic sulfonate-based modifier component included in the yarn through an alkali reduction process. It is expressed (FIG. 3 ), and due to such yarn surface effect, it is possible to realize natural texture and color.
이때, 사용되는 유기 술폰산 금속염계 개질제는 R-SO3-Na+의 구조식을 가지는 물질을 사용할 수 있으며, 상기 R은 탄소수 1 내지 20의 알킬기를 갖는다. 바람직하게는 소듐 도데실 술포네이트를 사용하는 것이다.At this time, the organic sulfonic acid metal salt-based modifier used may be a material having a structural formula of R-SO3 -Na+ , wherein R has an alkyl group having 1 to 20 carbon atoms. Preferably, sodium dodecyl sulfonate is used.
또한 유기 술폰산 금속염계 개질제의 바람직한 함량은 1 내지 5 중량%이며, 1 중량% 미만이면, 알칼리 감량처리에 의한 표면 특성 발현이 어려워 바람직하지 않고, 5 중량%를 초과하면, 과도한 개질제 첨가로 인하여 방사작업성 및 방사팩의 압력이 빨리 상승하는 문제를 초래한다.In addition, the preferable content of the organic sulfonic acid metal salt-based modifier is 1 to 5% by weight, if less than 1% by weight, it is not preferable to express the surface properties by alkali weight loss treatment, if it exceeds 5% by weight, spinning due to the addition of excessive modifier It causes a problem that the workability and the pressure of the spin pack rises quickly.
또한, 상기 제조된 개질 폴리에스테르 중합체는 원형구금을 통하여, 단독 용융방사하여 원형단면을 가지거나, 6-채널형의 특수 구금을 통하여 이형단면을 가지는 원사로 제조될 수 있다(도 4). 특히, 이형단면을 가지는 폴리에스테르 원사를 사용할 경우, 흡한속건성의 기능이 부여된다.In addition, the prepared modified polyester polymer may be made of a yarn having a circular cross section by circular melt, alone melt spinning, or having a cross-sectional cross section through a special mold of 6-channel type (FIG. 4 ). In particular, in the case of using a polyester yarn having a release cross section, a function of quick-drying and quick drying is imparted.
단계 1)의 미연신사는 2000∼2500mpm 방사속도로 방사하여 얻을 수 있으며, 2000mpm 미만이면, 방사수율의 문제점과 복합연신 후, 염반과 같은 염색결점이 발생할 가능성이 있으며, 2500mpm을 초과하여 실시하면, 복합 연신 후 심초사 간 사장차에 의한 염색불균일이 발생하는 문제가 있다.The unstretched yarn of step 1) can be obtained by spinning at a spinning speed of 2000 to 2500mpm, and if it is less than 2000mpm, there may be a problem of radiation yield and dyeing defects such as salt spots after complex stretching, and if it exceeds 2500mpm, There is a problem that the dye non-uniformity caused by the four seconds between the ecchospa after complex stretching.
본 발명의 상기 초사의 섬도는 150∼270 데니어가 바람직하며, 더욱 바람직하게는 150∼250 데니어이다. 이때, 상기 초사의 섬도 범위를 벗어날 경우, 복합연신 공정에서 최종 섬도 조정에 난점이 있으며, 사장차에 의한 염색불균일이 발생할 수 있다.As for the fineness of the said superfine yarn of this invention, 150-270 denier is preferable, More preferably, it is 150-250 denier. In this case, when the fineness of the superfine yarn is out of the range, there is a difficulty in adjusting the final fineness in the complex stretching process, and dyeing unevenness may occur due to the difference in order.
단계 2)는 고유점도 0.90∼1.20dl/g인 PTT 성분과 고유점도 0.40∼0.60dl/g인 PET 성분이 40:60 ∼ 60:40의 비율로 복합방사하여 제조된 잠재권축사를 2400∼2700mpm 방사속도로 방사하여 미연신사를 제조하여, 본 발명의 폴리에스테르 복합사의 심사성분으로 준비한다.Step 2) 2400-2700mpm of latent wound yarn prepared by the composite spinning of PTT component with intrinsic viscosity 0.90 ~ 1.20dl / g and PET component with intrinsic viscosity 0.40 ~ 0.60dl / g at a ratio of 40:60 to 60:40 Unstretched yarn is prepared by spinning at a spinning speed, and prepared as a screening component of the polyester composite yarn of the present invention.
즉, 본 발명의 폴리에스테르 복합사에 있어서, 심사성분으로 사용되는 원사는 고신축 폴리에스테르계 잠재권축사를 사용함으로써, 신축성을 발현한다. 상세하게는 상기 고신축 폴리에스테르계 잠재권축사는 열수축 성분이 서로 상이한 이종의 폴리머를 40:60 ∼ 60:40의 비율로 복합방사하여 제조되며, 더욱 바람직하게는 고유점도 0.90∼1.20dl/g인 PTT 성분과 고유점도 0.40∼0.60dl/g인 PET 성분이 50:50으로 이루어진 사이드-바이-사이드형의 PTT/PET계 잠재권축사를 사용한다.That is, in the polyester composite yarn of the present invention, the yarn used as the screening component expresses elasticity by using a high-stretch polyester-based latent yarn. In detail, the high-stretch polyester-based latent crimp is manufactured by complex spinning of different polymers having different heat shrinkage components at a ratio of 40:60 to 60:40, and more preferably intrinsic viscosity of 0.90 to 1.20 dl / g. A PTT / PET latent wound yarn of a side-by-side type composed of 50:50 of a PTT component and a PET component having an intrinsic viscosity of 0.40 to 0.60dl / g is used.
이때, 고수축부인 PTT 성분이 60%를 초과하면, 방사공정에서 곡사현상(구금 직하에서 폴리머가 한쪽으로 치우쳐 들러붙는 현상)에 의하여 방사작업성이 불량하며, 저수축부인 PET 성분이 60%를 초과하면, 충분한 신축성 발현이 불가능하다. 상기 비율로 제조된 본 발명의 잠재권축사는 그 단면이 사이드-바이-사이드형, 편심형, 중실원형 또는 땅콩형을 갖는다.At this time, if the PTT component, which is a high shrinkage part, exceeds 60%, the spinning workability is poor due to the curvature phenomenon (a phenomenon in which the polymer sticks to one side directly under the detention) in the spinning process, and the PET component as the low shrinkage part is 60%. If exceeded, sufficient elastic expression is not possible. The latent crimping yarn of the present invention produced at the above ratio has a cross-section of a side-by-side, eccentric, solid or peanut.
또한, 본 발명의 폴리에스테르 복합사에 있어서, 고유점도 0.90∼1.20dl/g의 PTT 성분을 방사할 경우, PET 성분은 상기 PTT 성분과의 충분한 수축차를 발현시키기 위해 상대적으로 낮은 고유점도 0.40∼0.60dl/g 범위를 사용한다. 그 결과, PTT 성분의 분자쇄 구조적 특성과 상기 PTT 성분의 고유점도에 의한 고수축부 형성과 낮은 고유점도의 저수축 특성으로 인하여 크림프가 발현된다.Further, in the polyester composite yarn of the present invention, when spinning the PTT component having an intrinsic viscosity of 0.90 to 1.20 dl / g, the PET component has a relatively low intrinsic viscosity of 0.40 to 1 to express a sufficient shrinkage difference with the PTT component. Use the 0.60 dl / g range. As a result, the crimp is expressed due to the molecular chain structural characteristics of the PTT component and the high shrinkage portion formed by the intrinsic viscosity of the PTT component and the low shrinkage characteristic of the low intrinsic viscosity.
2)의 미연신사는 상기 잠재권축사를 2400∼2700mpm 방사속도로 방사하여 얻을 수 있으며, 2400mpm 미만이면 방사수율에 의한 경제성의 문제점과 복합연신 후 배향차에 의해 권축율이 저하될 우려가 있으며, 2700mpm을 초과할 경우, 방사작업성이 불량해지는 문제가 있다.Unstretched yarn of 2) can be obtained by spinning the latent crimping yarn at a spinning speed of 2400 to 2700mpm, and if it is less than 2400mpm, there is a possibility that the crimping rate may be lowered due to the economic problems due to the yield of radiation and the orientation difference after the complex stretching. If it exceeds 2700mpm, there is a problem that the radioworkability is poor.
또한, 본 발명의 상기 심사의 섬도는 70∼160 데니어가 바람직하며, 이때, 심사의 섬도가 70 데니어 미만이면, 전체 복합사에서 차지하는 비율이 낮아 충분한 신축성을 발휘하지 못하여 바람직하지 않고, 160 데니어를 초과 시 복합사에서 차지하는 혼합비율이 상대적으로 높아져 경제성 문제가 제기된다.In addition, the fineness of the screening of the present invention is preferably 70 to 160 denier. At this time, if the fineness of the screening is less than 70 denier, the proportion of all composite yarns is low, so that the elasticity of the screening is not satisfactorily exhibiting sufficient elasticity. If exceeded, the mix ratio of composite companies will be relatively high, raising economic problems.
단계 3)은 상기 단계 1)의 미연신사를 초사로 하고, 단계 2)의 미연신사를 심사로 하여, 상기 심사 및 초사간의 중량비를 30 내지 40 : 70 내지 60의 비율로 복합연신한 후, 공기교락하여, 폴리에스테르 복합사를 제조하는 것이다.In step 3), the non-drawn yarn of step 1) is used as the yarn, and the non-drawn yarn of step 2) is used as the screening, and the composite ratio of the weight ratio between the screening and the yarn is 30 to 40:70 to 60, and then air It entangles and manufactures a polyester composite yarn.
상기 이종의 소재원사를 복합 연신함에 있어, 스트레치 직물 제조를 위한 충분한 신축성을 발현하기 위해서는 심사와 초사간의 비율이 30 내지 40: 70 내지 60을 유지하는 것이 바람직하며, 심사 비율이 30% 미만이면, 충분한 신축성 발현이 어려우며, 40%를 초과할 경우에는 최종 제품에서 과축 문제가 발생할 수 있고, 심초사간 염색 불균일, 경제적인 문제점 등이 있다.In the composite drawing of the different kinds of material yarns, in order to express sufficient elasticity for the production of stretch fabric, it is preferable to maintain the ratio between the screening and the super yarn 30 to 40: 70 to 60, if the screening ratio is less than 30%, It is difficult to develop sufficient elasticity, and if it exceeds 40%, there may be an overcontraction problem in the final product, and there may be uneven interepiary dyed dye, and economic problems.
본 발명의 신축성 폴리에스테르 복합사의 최종 섬도는 100 내지 250 데니어이며, 최종 섬도가 100 데니어 미만일 경우, 최종 원단에서 후도감이 부족하여 주 용도인 바지류(pants)에 적합하지 못하다.The final fineness of the stretchable polyester composite yarn of the present invention is 100 to 250 denier, when the final fineness is less than 100 denier, it is not suitable for the main purpose pants (pants) due to lack of a sense of finish in the final fabric.
도 2는 본 발명에서 사용하는 복합연신 장치의 모식도로서, 상기 단계 1)의 미연신사Figure 2 is a schematic diagram of a composite drawing apparatus used in the present invention, the non-drawn yarn of step 1)

이때, 본 발명의 PTT/PET의 폴리에스테르계 잠재권축사는 열처리 공정을 통하여 열수축 성분이 상이한 상기 성분으로 인한 자연스런 크림프 발현이 가능하다. 바람직한 열처리 온도는 150∼180℃에서 수행하는 것이다.At this time, the polyester-based latent crimp of the PTT / PET of the present invention is capable of natural crimp expression due to the above-mentioned different components of the heat shrink component through the heat treatment process. Preferred heat treatment temperature is carried out at 150 to 180 ℃.

도 3은 본 발명의 초사로 사용된 개질 폴리에스테르 섬유를 알칼리 감량처리한 후, 표면을 전자주사현미경으로 관찰한 결과로서, 알칼리 감량공정에서 개질 폴리에스테르 섬유에 첨가된 유기 술폰산염계 개질제 성분이 용해되면서 원사 표면에 섬유축 방향으로 자연스러운 요철효과가 발현되는 것이다. 이때, 촉감으로 느낄 수 있을 정도의 15% 이상 알칼리 감량처리를 하여야 하며, 바람직하게는 25%이상인 경우 충분한 피브릴 효과 발현이 가능함을 전자현미경 사진을 통해 확인하였다.Figure 3 is an alkali weight loss treatment of the modified polyester fiber used as the superfiber of the present invention, the surface was observed by electron scanning microscope, the organic sulfonate-based modifier component added to the modified polyester fiber in the alkali reduction process is dissolved The natural uneven effect is expressed in the direction of the fiber axis on the surface of the yarn. At this time, the amount of alkali loss treatment should be 15% or more, which is sufficient to feel the touch, preferably 25% or more, it was confirmed through electron micrographs that sufficient fibril effect can be expressed.
특히, 본 발명의 신축성 폴리에스테르 복합사에 있어서, 상기 초사가 유기 술폰산염계 개질제로 개질된 폴리에스테르 원사이고, 상기 원사가 원형단면 또는 이형단면의 원사를 포함하며, 이형단면의 경우는 습한속건성의 기능이 부여된다.In particular, in the stretchable polyester composite yarn of the present invention, the superfiber yarn is a polyester yarn modified with an organic sulfonate-based modifier, and the yarn includes a circular cross-section or a release cross-section yarn, and in the case of a release cross-section, the wet quick-drying Function is granted.
