특허등록 제 10-1275671호(고보온성 부직포 및 이의 제조방법)은 가벼우면서 보온성이 우수하고, 경제적인 부직포 및 이의 제조방법을 개시사고 있는데, 원료를 기준으로, 폴리에스테르, 아크릴, 폴리프로필렌, 폴리에틸렌, 우레탄, 레이온류 및 아세테이트로 이루어진 그룹으로부터 선택되는 단섬유(Staple Fiber)로 이루어진 직경 4 내지 15 ㎛의 극세 섬유 60 내지 98 중량%,직경 15 내지 40 ㎛의 중공섬유, 이형단면섬유, 시스/코어(Sheath/core)형 섬유, 콘쥬게이트(Conjugate) 소재섬유 또는 이들의 혼합 섬유 1 내지 30 중량%, 및 저융점 섬유 1 내지 12 중량%를 포함하고, 저융점 섬유는 히팅에 의해 녹아서 극세 섬유 및 중공섬유, 이형단면섬유, 시스/코어형 섬유, 콘쥬게이트 소재섬유 또는 이들의 혼합 섬유를 결합시키며,소면기법에 의해 제조되는 것을 특징으로 하는 고보온성 부직포을 개시하고 있다.Patent No. 10-1275671 (a high-temperature nonwoven fabric and a method for producing the same) discloses an economical nonwoven fabric having excellent light insulation and excellent warm-keeping properties and a method for producing the nonwoven fabric. The nonwoven fabric is made of polyester, acrylic, polypropylene, polyethylene 60 to 98% by weight of ultrafine fibers having a diameter of 4 to 15 占 퐉 and made of short fibers (Staple Fiber) selected from the group consisting of urethane, rayon and acetate; hollow fibers having a diameter of 15 to 40 占 퐉; 1 to 30% by weight of a sheath / core type fiber, a conjugate type fiber or a mixture thereof, and 1 to 12% by weight of a low melting point fiber, wherein the low melting point fiber is melted by heating, And hollow fiber, modified cross-section fiber, sheath / core-type fiber, conjugate material fiber, or mixed fiber thereof, It discloses insulation bujikpoeul.

상기 소개된 문헌에 개시된 기술은 구성섬유의 융점에 가까운 온도로 열처리하여 열접착에 의해 보온성 물체를 제조하고 있으나, 벌키한 특성이 미흡하여 복원성이나 보온성이 충분히 발휘되지 못하는 단점이 있다. 이는 보온재를 구성하는 섬유의 배향이 주로 길이방향으로만 되어 있기 때문인데, 이러한 단방향 배향섬유 보온재는 형태안정성도 좋지 못하여 세탁 후 제품이 뭉치는 현상이 발생된다. Although the technique disclosed in the above-mentioned document is heat-treated at a temperature close to the melting point of the constituent fibers to produce a heat-insulating object by thermal bonding, there is a disadvantage that sufficient bulkiness is insufficient and stability and warmth are not sufficiently exhibited. This is because the orientation of the fibers constituting the heat insulating material is mainly oriented in the longitudinal direction. Such a unidirectional oriented fiber insulating material has poor shape stability, so that the products are bundled after washing.

Here, the other staple fibers may be selected from the group consisting of polyester short fibers, acrylic short fibers, polypropylene short fibers, polyethylene short fibers, PET / PP conjugate short fibers, PTT (Polytrimethylene Terephthalic acid) , Which is softened with a low modulus and has excellent elastic restoring force due to a crystal structure of a zigzag form), rayon staple fibers and acetate staple fibers, and among them, Based on the total weight of the fibrous aggregate, 5-30% by weight of Low Melting staple fibers. The low-tangential fiber is a fiber aggregate constituting a part of the fibrous body constituting the fibrous aggregate, and unlike the ordinary polyester fiber which melts at a temperature of 265 DEG C or higher, the fiber which is melted at a relatively low temperature (about 100-200 DEG C) It is the role of intertwining. Such low melting point fibers are prepared by controlling the molecular weight of conventional fiber forming ability polymers, controlling additives, and the like, and they are well known to those skilled in the art. Worldwide, Huvis, Woongjin Chemical, Esfibervison, etc. are well known as a manufacturer.

본 발명은 보온성을 달성하기 위한 기초소재로서 극세섬유를 섬유집합체 전체중량을 기준으로 50-80 중량%을 포함하도록 하고, 열접착을 위한 저융점 단섬유를 전체 섬유집합체를 기준으로 5-30중량% 포함하도록 하여 열접착에 의한 섬유집합체를 형성하되, 열잡착된 웹을 X자 크로스 랩핑(Crosslapping)하여 적층하여 섬유집합체를 구성하는 섬유의 배향을 단방향이 아닌 2방향(MD 방향 및 CD방향)으로 하여 벌키성, 보온성, 형태안정성을 향상시킨 것에 특징이 있다.The present invention relates to a thermoplastic resin composition comprising 50 to 80% by weight of microfine fibers as a base material for achieving thermal insulation, based on the total weight of the fiber aggregate, and a low melting point staple fiber for thermal bonding, (MD and CD directions) of the fibers constituting the fiber aggregate are measured by cross-lapping the thermally adhered webs by X-crossing, , Which is characterized in that the bulky nature, warmth and shape stability are improved.

여기서, 크로스 랩핑이라 함은 MD(Machine Direction)의 솜과 CD(Cross Direction)의 솜을 가로 질러서(X 자로) 배향시킨다는 것인데, 일반적으로 MD(Machine Direction)로 배향시 강도는 CD(Cross Direction)로 배향시 강도보다 1.5~1.8배 정도 더 강하게 나타나는데, 이는 섬유의 배향도에 기인한다. 본 발명에서는 크로스 래퍼(Crosslapper)라는 장비를 이용하여 보온성 충진제의 겹침각도를 30-90도 범위내에서 X자로 적층하는 것이다.Cross-lapping refers to orienting the cotton of the MD (Machine Direction) and the cotton of the CD (Cross Direction) across (X-direction). Generally, when orienting to MD (Machine Direction) , Which is about 1.5 ~ 1.8 times stronger than the strength when orientated to the substrate, due to the degree of orientation of the fibers. In the present invention, the overlap angle of the warmth filler is laminated in X-shape within a range of 30-90 degrees using a crosslapper.

상기 X자 크로스 랩핑 각도는 30도 ~ 90도 이내로 하는데, 30도 미만에서는 MD 배향 방향과 실질적으로 동일하여 벌키성면에서는 큰 차이가 없어 30도 ~ 90도로 크로스 랩핑(Cross lapping)한다. Cross-lapping angle of the X-letter is within 30 to 90 degrees. If the angle is less than 30 degrees, the cross-lapping angle is substantially equal to the MD alignment direction.

또한 본 발명은 중공섬유, 이형단면섬유, 콘쥬게이트(복합, Conjugate)섬유로 구성된 군으로부터 선택된 1종 이상의 단섬유를 더 포함할 수도 있는데, 이에 의해 섬유들의 물리적 결합력을 향상시키고, 섬유층 사이의 공극을 유지 및 확대시키도록 하였다. 또한 상기 섬유의 사용으로 Z방향으로도 섬유가 배향되게 하여 벌키성, 보온성, 형태안정성을 더욱 향상시킨 것에 특징이 있다. 상기 중공섬유, 이형단면섬유, 콘쥬게이트(복합, Conjugate)섬유로 구성된 군으로부터 선택된 1종 이상의 단섬유는 상기 극세섬유중에 포함된 것일 수도 있고, 상기 기타 단섬유중에 포함된 것일 수 있고, 또한 상기 극세섬유중 및 상기 기타 단섬유 모두 중에 포함된 것일 수 있다. 본 발명의 실시예에서 상기 섬유는 기타 단섬유 중에 포함된다.The present invention may further comprise at least one short fiber selected from the group consisting of a hollow fiber, a sectioned cross-section fiber, and a conjugate fiber, thereby improving the physical binding force of the fibers, To maintain and expand. Further, by using the above-mentioned fibers, the fibers are oriented in the Z direction, which further enhances the bulky property, warmth property, and shape stability. The at least one short fiber selected from the group consisting of hollow fibers, modified cross-section fibers and conjugate fibers may be contained in the microfine fibers or may be contained in the other short fibers, May be contained in both the microfine fibers and the other short fibers. In an embodiment of the present invention, the fibers are included in other staple fibers.

콘쥬게이트(복합) 섬유는 두 종류의 성분이 다른 섬유형성가능한 고분자 재료를 동일 방사구(紡絲口)로부터 압출하여 만든다. 섬유의 단면은 두 성분이 2층으로 나뉘어 접합된 구조를 보인다. 열수축성이나 팽윤성이 다른 두 재료를 사용하므로, 방사한 후의 열처리나 습윤 ·건조 처리에 의해서 마치 바이메탈이 구부러지는 것처럼, 수축성이 큰 섬유는 안쪽으로 구부러져, 전체적으로 나선상의 권축(捲縮) 형태를 보이게 되는데, 이 때문에 제품이 되었을 때 풍만한 촉감과 큰 보온성을 얻는다. 천연의 양모섬유의 특이한 구성에 기인한 것이다.The conjugate (composite) fiber is produced by extruding a polymer material capable of forming two different kinds of fibers from the same spinneret. The cross section of the fiber shows a structure in which the two components are spliced into two layers. Since the two materials having different heat shrinkability and swelling property are used, the fiber having high shrinkage is bent inward, as if the bimetal is bent by the heat treatment after the spinning and the wetting and drying treatment, and the spiral crimping Because of this, when it becomes a product, it obtains a feeling of boldness and a great warmth. It is due to the unique composition of natural wool fibers.

이러한 콘쥬게이트(복합) 섬유는 본 발명에서 열에 의하여 크림프가 형성되어 Z 방향으로의 배향성을 가질 수 있으며, 벌키성을 갖게 되어 제품의 보온성을 향상시킬 수 있게된다. 본발명에 사용되는 상기 콘쥬게이트 섬유의 형태는 나란히 있는 형(side-by-side), 덮개와 심형(sheathcore) 등 2종류가 있으며 일반적으로 3~15%의 중공율(섬유자체(중공사)의 중공율)을 갖도록 하는 것이 바람직하다.In the present invention, such conjugate (composite) fibers have a crimp formed by heat and can have orientation in the Z direction, and have bulky properties, so that the warmth of the product can be improved. There are two types of conjugate fibers used in the present invention, namely side-by-side, cover and sheathcore, and generally have a hollow ratio of 3 to 15% Of the hollow portion).

이형단면 섬유(이형사(異型絲))는 단면이 이형이어서 섬유체 사이에 공기층이 형성되며 보온성을 뛰어나게 할 수 있다. 또한 이형단면사 자체를 중공형태로 하게되면 공기층을 더 많이 형성하여 보온성 및 반발탄성이 좋게 유지할 수 있다.The modified cross-section fiber (heterogeneous yarn) has an uneven cross-section, so that an air layer is formed between the fibrous bodies and the warming property can be improved. In addition, if the cross-section yarn itself is formed into a hollow shape, more air layer can be formed to maintain a good warmth and rebound resilience.

배향을 위해서는 상기 중공섬유, 이형단면섬유, 콘쥬게이트(복합, Conjugate)섬유로 구성된 군으로부터 선택된 1종 이상의 단섬유를 전체 섬유집합체를 기준으로 중량기준으로 3~10 중량% 함유시켜 제작하며, 상기 섬유를 혼면(mixing)하여 Z 방향으로 배향 시킬 수 있다. 10중량% 초과 함유시 반발탄성은 좋으나 유연성(soft)성이 감소하여 상품성이 떨어지며 3중량% 미만일 경우에는 배향성에 큰 영향이 없다.In order to achieve the orientation, at least one short fiber selected from the group consisting of hollow fiber, modified cross-section fiber and conjugate fiber is prepared by containing 3 to 10% by weight based on the whole fiber aggregate, Fibers can be mixed and aligned in the Z direction. If it is contained in an amount of more than 10% by weight, the rebound resilience is good, but the softness is reduced, resulting in poor merchantability. When the content is less than 3% by weight,

콘쥬게이트 섬유의 성분으로는 PPT/PET, PET/PET, PP/PET 등을 활용 할 수 있다. PPT / PET, PET / PET, and PP / PET can be used as the components of the conjugate fiber.

상기의 공정에 의해, 제조된 본 발명의 보온성 충진제는 침구용으로 활용하는 경우, 중량 70g/m2, 후도 5.5mm 정도의 단일층으로 제작되며, 제품에 따라서 상기 단일층을 6~9층으로 적층하여 사용한다. 여기서 상기 수치는 예시적인 것이며, 요구되는 기능에 따라 제품의 용도 등에 따라 가변적이다.According to the product, the heat-resistant filler of the present invention is made into a single layer having a weight of about 70 g / m 2 and a thickness of about 5.5 mm when used as a bedding, . Here, the above values are illustrative and may vary depending on the intended use of the product or the like depending on the required function.

본 발명에 따르면 보온성 충진제을 구성하는 섬유의 결합 수단으로서 수지를 사용하지 않고 열접착에 의해 결합시킴으로서 솜의 벌키성을 유지시켜 보온성을 향상시키며, 수지의 경화에 의한 딱딱한 감촉을 제거하여 소프트한 터치감을 유지시키며, 이불솜 제작 시 열접착된 섬유체를 접는(folding) 형태의 적층이 아닌 X자 크로스랩핑(cross lapping) 형태로 하여 섬유체를 구성하는 섬유의 배향을 MD 방향뿐 아니라 CD 방향으로도 배향이 되게하여 제품의 벌키성과 형태안정성이 우수한 보온성 충진제가 제공된다.According to the present invention, as a bonding means of fibers constituting a warming filler, bonding is performed by thermal bonding without using a resin, thereby maintaining warmth of the cotton by maintaining the elasticity of the cotton and removing a hard texture by hardening the resin, And the heat-bonded fibrous body in the preparation of the bedding cotton is formed into an X-shaped cross lapping shape instead of a folding-type laminated structure, so that the orientation of the fiber constituting the fibrous body is changed not only in the MD direction but also in the CD direction Thereby providing a warming filler excellent in bulkiness and form stability of the product.

또한 중공섬유, 이형단면섬유, 시스/코어(Sheath/core)형 섬유 및 콘쥬게이트(Conjugate)섬유를 사용하여 Z 방향으로도 섬유가 세워지도록 하여 반발탄성이 있어 제품의 형태안정성이 우수한 보온성 충진제가 제공된다.In addition, by using hollow fiber, modified cross-section fiber, sheath / core type fiber and conjugate fiber, the fiber is raised in the Z direction, / RTI >
