한편, 직물형 패딩원단용 충진섬유에 관한 종래기술로서 일본 특개 2016-56483호 등에서는 가연가공(Draw-textured)된 열가소성 멀티필라멘트인 심사(Core yarn)와 초사(Effect yarn)를 사용하여 타슬란(Taslan) 가공으로 입체적인 루프(Loop)를 형성시키면서 상기 심사와 초사를 교락시킨 패딩원단용 충진섬유를 게재하고 있고, 일본 특개는 58-146385호에서는 열가소성 멀티필라멘트인 심사와 루프섬유인 초사를 공기교락시킨 후 융착시킨 패딩원단용 충진섬유를 게재하고 있으나, 상기 종래의 직물형 패딩원단용 충진섬유들은 볼륨감이 너무 높아서 직물형 패딩원단 제직공정에 적용이 불가능한 문제점이 있었다.On the other hand, as a prior art for fabric-type padding fabric filling fibers, in Japanese Patent Application No. 2016-56483, etc., taslan was produced using core yarns and effect yarns, which are draw-textured thermoplastic multifilaments. Taslan) is a padding fabric for padding fabrics that intersects the above-mentioned screening and yarn while forming a three-dimensional loop by processing, and Japanese Patent No. 58-146385 discloses a thermoplastic multifilament screening and roof fiber-like yarn. After filling, the filling fibers for the padded fabric that have been fused are placed, but the conventional fabric-type padding fabric has a high volume so that it is impossible to apply to the fabric-type padding fabric weaving process.

또 다른 직물형 패딩원단용 충진섬유에 관한 종래기술로서 폴리에스터 멀티필라멘트인 심사와 초사를 공기교락 등의 방법으로 물리적으로 결합시킨 직물형 패딩원단용 충진섬유로 알려져 있으나, 상기 종래의 직물형 패딩원단용 충진섬유는 폴리에스터 멀티필라멘트의 우수한 권축특성 때문에 볼륨감은 우수하나 폴리에스터 멀티필라멘트의 낮은 클림프 수축율 때문에 권축회복력이 크게 저하되는 문제가 있었다.As a prior art for another fabric type padding fabric, it is known as a fabric type padding fabric that physically combines polyester multifilament screening and yarn with air interlocking methods, but the conventional fabric type padding The filling fiber for fabric has excellent volume feeling due to the excellent crimp characteristics of the polyester multifilament, but there is a problem in that the crimp recovery force is greatly reduced due to the low crimp shrinkage of the polyester multifilament.

또 다른 직물형 패딩원단용 충진섬유에 관한 종래기술로서 나일론 멀티필라멘트인 심사와 초사를 공기교락 등의 방법으로 물리적으로 결합시킨 직물형 패딩원단용 충진섬유도 알려져 있으나, 상기 종래의 직물형 패딩원단용 충진섬유는 나일론 멀티필라멘트의 높은 클림프 수축율 때문에 권축회복력은 우수하나, 나일론 멀티필라멘트의 낮은 권축발현성 때문에 볼륨감이 크게 저하되는 문제가 있었다.As a prior art for another fabric-type padding fabric, the filling fiber for a fabric-type padding fabric that physically combines nylon multifilament screening and yarn with air interlacing is also known, but the conventional fabric-type padding fabric is known. The filling fiber for the dragon has excellent crimp recovery due to the high crimp shrinkage of the nylon multifilament, but there is a problem in that the volume feeling is greatly reduced due to the low crimp expression of the nylon multifilament.

본 발명의 과제는 볼륨감과 권축회복력이 뛰어나 직물형 패딩원단을 제조시 직물형 패딩원단 내에 공기층을 형성시켜 보온성을 향상시킴과 동시에 형태안정성도 향상시킬 수 있는 직물형 패딩원단용 충진섬유를 제공하는 것이다.An object of the present invention is to provide a filling-type fiber for fabric-type padding fabric that is excellent in volume and crimp recovery, forms an air layer in the fabric-type padding fabric when manufacturing fabric-type padding fabric, and improves heat retention and also improves shape stability. will be.

이와 같은 과제를 달성하기 위해서, 본 발명에서는 (ⅰ) 고수축성 폴리에스터 멀티필라멘트인 심사와 (ⅱ) 폴리에스터 멀티필라멘트와 나일론 멀티필라멘트의 권축사 및 폴리에스터 폴리머와 나일론 폴리머가 섬유 길이방향을 따라 접합되어 있는 복합섬유 중에서 선택된 1종의 원사인 초사를 물리적으로 결속시킨 다음 이완 열처리하여 패딩원단용 충진섬유를 제조한다.In order to achieve such a task, in the present invention, (i) high shrinkage polyester multifilament screening and (ii) polyester multifilament and nylon multifilament crimped yarn, polyester polymer and nylon polymer along the fiber length direction Padding fabric for the padding fabric is manufactured by physically binding one type of yarn selected from the bonded composite fibers and then relaxing heat treatment.

이때, 상기 심사의 열수축율을 초사의 열수축율 보다 5~37% 높게 조절해 주고, 초사의 함량을 충진섬유 전체 중량대비 55~75중량%로 조절해 준다.At this time, the heat shrinkage rate of the screening is adjusted to be 5 to 37% higher than that of the weed yarn, and the content of the weed yarn is adjusted to 55 to 75% by weight relative to the total weight of the filled fiber.

상기 심사와 초사를 물리적으로 결합시킬 때에는 공기교락, 커버링 및/또는 꼬임과 같은 결속수단을 사용한다.When physically combining the screening with the yarn, binding means such as air interlocking, covering and/or twisting are used.

본 발명의 심사는 초사를 충진섬유의 외부로 도출시켜 충진섬유의 볼륨감을 증대시키도록 수축율이 높은 폴리에스터 멀티필라멘트로 구성되고, 본 발명의 초사는 우수한 권축성능에 의해 볼륨감을 향상시킬 수 있는 폴리에스터 멀티필라멘트와 우수한 클림프 수축율에 의해 권축회복력을 향상시킬 수 있는 나일론 멀티필라멘트의 권축사 또는 폴리에스터/나일론 복합섬유로 구성된다.The screening of the present invention is composed of a polyester multifilament having a high shrinkage rate so as to increase the volume of the filled fiber by leading the yarn to the outside of the filled fiber, and the yarn of the present invention is a poly that can improve the sense of volume by excellent crimp performance. It is composed of polyester multifilament and nylon/filament crimped yarn of nylon multifilament or polyester/nylon composite fiber which can improve crimping recovery force by excellent crimp shrinkage.

그로인해, 본 발명은 볼륨감과 권축회복력이 우수하기 때문에 이로 제조된 직물형 패딩원단에 부동공기층을 만들어 보온성을 크게 향상시킴과 동시에 양호한 형태안정성을 구현한다.As a result, the present invention is excellent in volume and crimping recovery, so a floating air layer is formed on the fabric-type padding fabric made of this, thereby greatly improving heat retention and realizing good shape stability.

이하, 첨부한 도면 등을 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail through the accompanying drawings.

충진섬유는 외피직물과 내피직물의 사이에 섬유형태 또는 직물형태로 위치하여 볼륨감을 증대시켜서 부동공기층을 만들어 쿠션 및 보온기능을 발휘하는 역할을 한다. Filling fibers are located in the form of fibers or fabrics between the outer fabric and the inner fabric to increase the volume and create a floating air layer to play a role in exerting cushioning and warming functions.

따라서 쿠션재나, 침구류, 패딩원단 등으로 사용되는 충진섬유는 볼륨감을 증대시킬 수 있는 특성을 갖게 하는 것이 가장 중요하다.Therefore, it is most important that the filling fibers used as cushioning materials, bedding, and padding fabrics have properties that can increase the volume.

이러한 용도로 사용되고 있는 충진섬유용 소재로는 사가공에 의한 권축형성성과 복합사가공성이 아주 우수하고 흡습성이 매우 낮지만 가격도 저렴한 폴리에스터계 섬유가 가장 많이 사용되고 있다.As the material for the filling fiber used for this purpose, polyester fiber is most frequently used, which is excellent in crimp formation by sand processing and composite processability, and has very low hygroscopicity, but is also inexpensive.

충진섬유의 역할은 쿠션재나, 침구류, 패딩원단 등의 볼륨감을 향상시켜야할 뿐만 아니라 외력이 제거된 후 원래의 상태로 형상을 복구시켜야 하는 것이다.The role of the filling fiber is to improve the volume of cushion materials, bedding, and padding fabrics, as well as restore the shape to its original state after the external force is removed.

충진섬유의 볼륨감을 높이기 위한 방법으로 섬유의 권축가공, 복합권축가공, 이수축혼섬가공, 특수 연신가공과 같은 다양한 사가공방법이 사용되고 있는데 이러한 기술들을 용도에 맞도록 다양한 조건으로 폴리에스터계 섬유에 적용하게 되면 우수한 권축성이 발현되어 볼륨감이 높은 충진섬유로의 제조가 가능하게 된다.As a method to increase the volume of the filling fiber, various yarn processing methods such as crimping of the fiber, complex crimping, diaxial shrinking, and special stretching are used. When applied, excellent crimping properties are exhibited, which makes it possible to manufacture a high volume filling fiber.

그러나 폴리에스터 섬유로 제조된 볼륨감이 우수한 충진섬유를 적용한 제품을 온도가 낮은 환경에서 사용하게 되면 권축회복력이 매우 약하다는 단점이 있다는 것을 본 발명자는 알게 되었다. However, the present inventors have found that when a product to which a filler fiber having excellent volume feeling made of polyester fibers is applied is used in a low temperature environment, the crimp recovery power is very weak.

충진섬유의 권축회복력은 섬유의 클림프 수축력(crimp contraction)과 직접적으로 연계되어 있는데, 폴리에스터나 나일론과 같은 대부분의 열가소성 섬유의 클림프 수축력(crimp contraction)은 열처리 온도나 연신비 등에 의해서도 영향을 받지만 그 보다 큰 영향을 주는 것은 폴리머의 특성에 의존하는 성질을 가지고 있기 때문이다.The crimp recovery force of the filled fiber is directly related to the crimp contraction of the fiber, and the crimp contraction of most thermoplastic fibers such as polyester and nylon is affected by heat treatment temperature or elongation ratio, but more It is because it has properties that depend on the properties of the polymer.

일반적으로 클림프 수축력이 높을수록 원래의 상태로 회복하려는 충진섬유의 복원력이 높은 것을 의미하게 된다.In general, the higher the crimp shrinking force, the higher the resilience of the filling fiber to restore to its original state.

나일론섬유가 폴리에스터 섬유보다는 클림프 수축력이 높고 폴리에스터섬유는 습열 및 건열온도의 변화에 따라 클림프 수축력이 크게 변화되며, 특히 의류나 생활용 섬유제품을 착용하는 온도 영역에서 클림프 수축력이 낮아지는 현상을 보이고 있다. Nylon fiber has a higher crimp shrinkage than polyester fiber, and polyester fiber has a large change in crimp shrinkage due to changes in wet heat and dry heat temperature, and in particular, the crimp shrinkage decreases in the temperature range where clothing or household textile products are worn. have.

그러나 나일론섬유는 폴리에스터 섬유에 비하여 사가공기술에 의한 권축발현성이 낮고 신축성이 부족하며 폴리에스터 섬유에 비하여 초기 탄성계수가 낮고, 습도가 높기 때문에 100%를 충진섬유로 사용하는 것은 부적합하다는 사실을 확인하고 본 발명을 완성하였다.However, nylon fiber is less suitable for using 100% as a filler fiber because it has lower crimp expression and less elasticity than polyester fiber and has low initial elastic modulus and high humidity compared to polyester fiber. Confirmed and completed the present invention.

본 발명으로 개발한 충진섬유는 폴리에스터 섬유의 우수한 권축성능에 의한 볼륨감과 클림프 수축력이 우수한 나일론 섬유에 의한 권축회복력을 향상시킬 수 있는 특성을 부여할 수 있다는 것을 확인하였다.It was confirmed that the filling fiber developed with the present invention can impart properties that can improve the crimping recovery force of nylon fibers, which is excellent in volume and crimp shrinking force due to excellent crimp performance of polyester fibers.

본 발명의 충진섬유는 원단을 제직하는 공정에서 경사 및/또는 위사로 사용하는 것이기 때문에 섬유길이방향으로 연속성이 있어야 하므로 필라멘트를 권축가공하여 사용하는 것이 바람직하다.Since the filling fiber of the present invention is used as a warp and/or weft in the process of weaving a fabric, it is preferable to use it by crimping the filament since it must have continuity in the fiber length direction.

폴리에스터와 나일론의 장점을 충진섬유로 효율적으로 발현시키기 위해서는 권축가공을 한 폴리에스터 섬유와 나일론 섬유를 균일하게 복합시키는 것이었다.In order to efficiently express the advantages of polyester and nylon as filling fibers, the crimped polyester fibers and nylon fibers were uniformly combined.

충진섬유의 볼륨감을 높이기 위해서는 권축가공된 섬유를 단독으로 사용할 수도 있지만 이것보다는 열에 의한 수축률이 높은 심사와 열에 의한 수축률이 낮은 초사를 교락시켜 사용하는 것이 더욱 유리한 방법이었다. 이때 심사와 초사의 수축률의 차이가 클수록 충진섬유의 볼륨감은 증가하는 경향을 보인다.In order to increase the volume of the filling fibers, crimped fibers may be used alone, but rather than this, it is more advantageous to use a screen with high heat shrinkage and low heat shrinkage. At this time, the larger the difference between the shrinkage rate of screening and yarn, the more the volume of filling fibers tends to increase.

본 발명에 따른 직물형 패딩원단용 충진섬유는 (ⅰ) 고수축성 폴리에스터 멀티필라멘트인 심사와 (ⅱ) 폴리에스터 멀티필라멘트와 나일론 멀티필라멘트의 권축사 및 폴리에스터 폴리머와 나일론 폴리머가 섬유 길이방향을 따라 접합되어 있는 복합섬유 중에서 선택된 1종의 원사인 초사가 물리적으로 결속된 구조이며, 상기 심사의 열수축율이 초사의 열수축율 보다 5~37% 높고, 충진섬유 내 초사의 함량이 55~75중량%인 것을 특징으로 한다.The filling fiber for the fabric type padding fabric according to the present invention includes (i) a high-shrinkable polyester multifilament, and (ii) a crimped yarn of polyester multifilament and nylon multifilament, and a polyester polymer and nylon polymer in the fiber length direction. According to this, the first yarn selected from the composite fibers bonded together is a structure in which the yarn is physically bound, and the heat shrinkage rate of the screening is 5~37% higher than that of the yarn, and the content of the yarn in the filled fiber is 55 to 75% by weight. %.

상기 심사와 초사는 공기교락, 커버링 및 꼬임 중에서 선택된 1개 이상의 결속수단에 의해 물리적으로 결속되어 있다.The screening and yarn are physically bound by one or more binding means selected from air interlocking, covering, and twisting.
