Description

고강도 고탄력성 코어 구조의 복합방적사 및 그 제조방법{HIGH-STRENGTH AND HIGH-ELASTIC CORE FOR COMPOSITE YARN AND METHOD FOR MANUFACTURING THE SAME}Composite spun yarn with high-strength, high-elasticity core structure and manufacturing method thereof

본 발명은 복합방적사에 관한 것으로, 특히 나일론 필라멘트사에 스판사를 꼬임을 통한 심사를 이용한 고강도 고탄력성 코어 구조의 복합방적사 및 그 제조방법에 관한 것이다.The present invention relates to composite spun yarn, and more particularly, to a composite spun yarn having a high-strength, high-elasticity core structure and a method for manufacturing the same, using screening through twisting span yarn into nylon filament yarn.

방적사는 단섬유사라고도 하는데, 스테이플섬유를 방적 공정에서 한 올의 실이나 여러 올의 실을 합하여 꼬아 만든 실로서, 한 올로 형성된 소재나 꼬임이 느슨한 합사로 형성된 소재는 표면에 잔털이 있고 부드러우며, 또한 착용시 의복이 흐름이 자연스러우며 따뜻하다는 장점을 가지고 있다. 그러나, 인장력에 대하여 강도가 미약한 단점을 가진다.Spun yarn is also called monofilament yarn. It is a yarn made by twisting staple fibers by combining one yarn or several yarns in the spinning process. , It also has the advantage that the flow of clothing is natural and warm when worn. However, it has a weak strength against tensile force.

그에 반하여 필라멘트사는 장섬유사라고도 하는데, 실크와 같은 천연 필라멘트사도 이에 속하지만 통상적으로 방사공정으로 얻어지는 화학섬유를 말하고 질기고 잘 구겨지지 않는 장점을 가지고 있는 반면, 촉감이 좋지 못하고 보온성이 약한 단점을 가진다.On the other hand, filament yarn is also called long fiber yarn. Although natural filament yarn such as silk belongs to this category, it refers to a chemical fiber usually obtained through a spinning process and has the advantage of being tough and not wrinkled. have

상기의 방적사와 방사에 의해 얻어지는 폴리에스터 및 나일론 등의 필라멘트사는 그 특성과 용도가 상당히 다른 것으로 현재까지 방적사로서 또는 필라멘트사로서만 사용되어 각각의 특성만을 이용하는 제직에 사용되어 왔다.Filament yarns such as polyester and nylon obtained by spinning yarns have very different properties and uses, and have been used as spun yarns or only as filament yarns for weaving using only each characteristic.

그러나, 최근 섬유제품에는 인체친화적, 친환경적인 것에 더하여 복합적 기능성을 가진 섬유제품이 요구되고 있다. 복합사(이중 구조사)는 천연섬유의 단점을 보완하기 위해 개발된 제품으로 이종의 섬유로 구성된다. 이종의 섬유에 의해 다양한 기능을 발현하기 위한 복합사에 있어 장섬유와 단섬유를 이용한 장단복합사가 개발되어 왔다. 이러한 장단복합사는 장섬유의 외부를 단섬유의 실로 감싸거나, 단섬유의 실을 장섬유로 사선으로 겉을 감싸거나, 큰 데니어의 장섬유에 작은 데니어의 스판 장섬유를 감싸는 방식으로 개발되어 상용화되고 여러 용도로 제품화 중에 있다.However, in recent textile products, in addition to being human-friendly and eco-friendly, textile products with multiple functionalities are required. Composite yarn (double structure yarn) is a product developed to compensate for the disadvantages of natural fibers and is composed of heterogeneous fibers. Long and short composite yarns using long fibers and short fibers have been developed for composite yarns to express various functions by heterogeneous fibers. These long-short composite yarns have been developed and commercialized by wrapping the outside of long fibers with short-fiber yarns, wrapping short-fiber yarns with long fibers diagonally, or wrapping small-denier spandex long fibers around large-denier long fibers. It is being commercialized for various purposes.

그러나, 기술개발과 더불어 진보된 기술에 대한 고객의 니즈가 증대되고 있는 실정이며, 특히 신축성과 강성이 중요시되는 아웃도어, 스포츠용 의류 등에서는 더 높은 신축성과 함께 강성을 가짐과 동시에 필링(보푸라기)을 감소시키면서, 방적사의 단점인 구김을 최소화하여 고급스러운 터치감과 외관을 발현할 수 있는 신 섬유소재의 개발이 요구되고 있다.However, along with technology development, customer needs for advanced technology are increasing. In particular, outdoor and sports clothing, where elasticity and rigidity are important, have higher elasticity and rigidity and at the same time pilling (lint) It is required to develop a new fiber material that can express a luxurious touch and appearance by minimizing wrinkles, a disadvantage of spun yarn, while reducing

본 발명은 복합방적사에 관한 것으로, 특히 나일론 필라멘트사에 스판사를 꼬임을 통한 심사를 이용한 고강도 고탄력성 코어 구조의 복합방적사 및 그 제조방법에 관한 것이다.The present invention relates to composite spun yarn, and more particularly, to a composite spun yarn having a high-strength, high-elasticity core structure and a method for manufacturing the same, using screening through twisting span yarn into nylon filament yarn.

특히, 나일론 필라멘트사를 중심으로 스판사가 커버링된 심사를 통하여 고강도, 고탄력성을 가지는 복합방적사를 제공하여 원단의 스트레치성을 부여함과 동시에 필링(보푸라기)를 감소시키고, 방적사의 단점인 구김을 최소화하여 고급스러운 터치감과 외관을 발현할 수 있도록 하는 것을 기술적 특징으로 한다.In particular, by providing a composite spun yarn with high strength and high elasticity through a screening process in which span yarn is covered with a nylon filament yarn as the center, the stretch property of the fabric is provided, while pilling (lint) is reduced and wrinkles, a disadvantage of the spun yarn, are minimized.

도 1은 본 발명에 따른 고강도 고탄력성 코어 구조의 복합방적사의 단면도이고, 도 2는 본 발명에 따른 고강도 고탄력성 코어 구조의 복합방적사의 심사 구성을 나타내는 도면이다.1 is a cross-sectional view of the composite spun yarn having a high-strength, high-elasticity core structure according to the present invention, and FIG. 2 is a view showing the core structure of the composite spun yarn having a high-strength, high-elasticity core structure according to the present invention.

이하 본 발명의 바람직한 실시예에 따른 고강도 고탄력성 코어 구조의 복합방적사를 상세하게 설명하면 다음과 같다.Hereinafter, a composite spun yarn having a high-strength, high-elasticity core structure according to a preferred embodiment of the present invention will be described in detail.

본 발명의 고강도 고탄력성 코어 구조의 복합방적사는 심사를 나타내는 내피부(10)와 상기 심사를 감싸도록 이루어져 외피를 형성하는 외피부(20)로 이루어진다.The composite spun yarn having a high-strength, high-elasticity core structure of the present invention is composed of an inner skin 10 representing a yarn and an outer skin 20 forming an outer shell made to surround the yarn.

상기 내피부(10)는 나일론 필라멘트사(11)를 중심으로 스판사(12)(span yarn)의 나선형태 커버링을 통하여 형성되는 심사로 이루어진다.The inner skin 10 is composed of a screening formed through a spiral covering of a span yarn 12 around the nylon filament yarn 11.

이때, 상기 나일론 필라멘트사(11)는 20데니어 굵기로서 필라멘트 복수 개를 사용하게 되며, 이를 통한 강성을 확보할 수 있게 된다.At this time, the nylon filament yarn 11 has a thickness of 20 denier and uses a plurality of filaments, through which rigidity can be secured.

상기 스판사(12)는 15데니어 굵기로 이루어지는 것이 바람직하며, 상기 나일론 필라멘트사(11)를 중심에 두고 나선형태로 꼬여지게 되는데 스판사(12) 재질의 특징인 늘어나는 성질과 더불어 나선형태 꼬임을 통하여 신축성이 더욱 높아지게 된다.The span yarn 12 is preferably made of a thickness of 15 denier, and is twisted in a spiral shape with the nylon filament yarn 11 at the center. In addition to the stretching property, which is a characteristic of the material of the span yarn 12, spiral twist Through this, elasticity is further increased.

다만, 외피 균제도나 강성을 고려하여 상기 스판사(12)의 커버링시 TPM(Twist per meter) 1,000 ~ 1,200이 되도록 하는 것이 바람직하다.However, considering the uniformity or rigidity of the outer shell, it is preferable to set the TPM (Twist per meter) to 1,000 to 1,200 when covering the span yarn 12.

한편, 상기 스판사(12)를 상기 나일론 필라멘트사(11)의 표면에 커버링시 재질의 특성상 슬립이 발생함에 따라 상기 나일론 필라멘트사(11)의 표면에 스크레치를 부여하여 슬립을 억제할 수 있게 한다.On the other hand, when the span yarn 12 is covered on the surface of the nylon filament yarn 11, as slip occurs due to the nature of the material, the surface of the nylon filament yarn 11 is scratched to suppress slip .

이때, 상기 나일론 필라멘트사(11)의 표면에 스크레치를 부여하는 것은, 상기 나일론 필라멘트사(11)를 60~70℃의 약염기성의 탄산나트륨(Na₂CO₃)에 5분간 침지시킴으로써 달성할 수 있게 된다.At this time, applying scratches to the surface of the nylon filament yarn 11 can be achieved by immersing the nylon filament yarn 11 in weakly basic sodium carbonate (Na2CO3) at 60 to 70 °C for 5 minutes.

다음으로, 상기 외피부(20)는 단섬유로 이루어진 방적원료를 통하여 얻어진 조사를 겉사로 하여 상기 심사의 외표면을 감싸도록 하여 얻어지는 복합방적사의 외피를 형성하게 된다.Next, the outer skin 20 forms an outer skin of the composite spun yarn obtained by wrapping the outer surface of the screening with the outer yarn obtained through the spinning raw material composed of short fibers.

이때, 외피를 형성하는 조사는 면방적사 공정에서 혼타면-소면-연조-조방 공정까지 면 또는 폴리에스테르를 원료로 하여 방적을 통한 조사를 생산하고, 이후 정방공정에서 상기 나일론 필라멘트사(11)와 스판사(12)의 합사를 심사로, 상기 조사를 겉사로 사용하여서 복합방적사를 생산하게 된다.At this time, the irradiation to form the outer shell is produced by spinning using cotton or polyester as a raw material from the cotton spinning yarn process to the mixed cotton-carding-twisting-roving process, and then in the spinning process, the nylon filament yarn 11 and A composite spun yarn is produced by using the plying of the span yarn 12 as a screening and using the yarn as an outer yarn.

이때, 외피 공정인 면방적사 공정은 사이로필(Sirofil) 공정을 통하여 진행되는 것이 바람직하다. 그러나, 사이로필 방적 조건을 사용할 경우 방적 시 원사의 균제도나 강성 등에 문제가 발생할 수 있어 저속으로 공정을 진행하여야 하며, 권사/하조의 세팅온도나 시간도 기존보다 낮추어 사용하여야 한다.At this time, it is preferable that the cotton spun yarn process, which is the outer skin process, proceeds through a sirofil process. However, when using psyrofil spinning conditions, problems such as uniformity or stiffness of the yarn may occur during spinning, so the process must be performed at a low speed, and the setting temperature or time of the winding/lower thread must be lowered than before.

가령, 권사/하조시 속도는 500~600rpm, 세팅온도 60~70℃, 세팅시간은 30분으로 설정하는 것이 최적화된 값을 나타낸다.For example, setting the speed at 500 to 600 rpm, the setting temperature at 60 to 70° C., and the setting time at 30 minutes indicates an optimized value.

도 3은 본 발명에 따른 고강도 고탄력성 코어 구조의 복합방적사의 제조방법에 관한 순서도로써, 전술된 고강도 고탄력성 코어 구조의 복합방적사의 제조방법에 대하여 도 3을 참조하여 설명하기로 한다.3 is a flow chart of a method for manufacturing composite spun yarn having a high-strength, high-elasticity core structure according to the present invention, and the method for manufacturing the above-described composite spun yarn having a high-strength, high-elasticity core structure will be described with reference to FIG. 3 .

먼저, 나일론 필라멘트사(11)를 60~70℃의 탄산나트륨(Na₂CO₃)에 5분간 침지시켜 스크레치를 형성시킨다.(S100)First, the nylon filament yarn 11 is immersed in sodium carbonate (Na₂CO₃) at 60 to 70° C. for 5 minutes to form scratches. (S100)

그리고, 상기 나일론 필라멘트사(11)를 중심으로 스판사(12)(span yarn)의 나선형태 커버링을 통한 내피부(10)의 심사를 제조한다.(S200)Then, the inner skin 10 is examined through the spiral covering of the span yarn 12 around the nylon filament yarn 11. (S200)

마지막으로 단섬유로 이루어진 방적원료를 통하여 얻어진 조사를 겉사로 하여 상기 심사의 외표면을 감싸는 외피부(20)로 형성시키는 복합방적단계이다.(S300)Lastly, it is a composite spinning step in which the irradiation obtained through the spinning raw material made of short fibers is used as outer yarn to form an outer skin 20 surrounding the outer surface of the screening. (S300)

이때, 상기 스판사(12)의 커버링시 TPM이 1,000 ~ 1,200이 되도록 하는 것이 바람직하다.At this time, when covering the span yarn 12, it is preferable to set the TPM to 1,000 to 1,200.

이를 통하여 나일론 필라멘트사(11)의 강성과 스판사(12)의 신축성, 그리고 나일론 필라멘트사(11)를 중심으로 스판사(12)를 나선형태의 꼬임을 통한 심사를 통한 강화된 신축성을 제공할 수 있어 물성이 우수한 복합방적사를 제공할 수 있게 된다.Through this, the stiffness of the nylon filament yarn 11, the elasticity of the span yarn 12, and the nylon filament yarn 11 are centered on the span yarn 12 to provide enhanced elasticity through screening through twisting in a spiral form. Therefore, it is possible to provide a composite spun yarn having excellent physical properties.
