본 고안은 축구공용 원단의 적층구조의 개량에 관한 것이다.The present invention relates to the improvement of the laminated structure of the soccer ball fabric.

종래 축구공용 원단은 제2도에 예시된 바와 같이 두꺼운 천연피혁의 표면에는 우레탄수지를 2중으로 코팅(u')(u")시키고 그 이면에는 면범포지를 접착제(2)로 접착시킨 것이었으므로, 전체면에서 피혁이 차지하는 비중이 커서 그만큼 신축의 변화가 심하고, 면범포지는 습기에 약하여 흠습되면 공이 무거워지거나 썩어서 공의 강도를 저하시켜서 그 수명을 단축시키게되고, 또 표면층의 우레탄수지는 코팅에 의하여 적층된 것이므로 그 두께가 두꺼우면서도 균일하기 형성할수가 없고 코팅층의 강도도 그만큼 약하여 여러번 차번 쉬이 그 코팅층이 박리되거나 마모되어 습기나 수분의 침투가 용이하게 되고 공의 수명이 단축되어 버리는 원인이 되기도 하였다.In the conventional soccer ball fabric, as shown in FIG. 2, the surface of the thick natural leather was coated with a double urethane resin (u ') (u "), and the back surface was coated with an adhesive (2). In the whole surface, the proportion of leather is so large that the change of stretching is severe. If cotton cloth is weak due to moisture, the ball becomes heavy or rotted, which reduces the strength of the ball and shortens its life, and the urethane resin of the surface layer is applied to the coating. Because it is laminated, it cannot be formed thick and uniformly, and the strength of the coating layer is so weak that the coating layer peels or wears several times, which makes it easier to penetrate moisture and moisture, and also shortens the life of the ball. It was.

본 고안은 종래의 그와 같은 문제점을 해결하기 위하여 표면을 우레탄시이트로 구성하고 이면에 나일론 방수포를 삽착시키도록 하였는바 첨부도면에 의거하여 상술하면 다음과 같다.The present invention has been made in order to solve the problems of the prior art made of a urethane sheet and to insert a nylon tarpaulin on the back side according to the accompanying drawings as follows.

비교적 두께가 얇은 천연피혁(ℓ)의 표면에 연신한 우레탄시이트(u)를 접착제(1)로 접착시키고, 천연피혁(ℓ)의 이면에는 1-3매 정도의 나일론방수포(n)를 접착제(2)로 면범포지(c)와 천연피혁(ℓ)사이에 삽착시켜서 일정한 두께(h)의 축구공용 원단을 적층구성 하였다. 이와 같이 구성된 본 고안 축구공용원단의 작용효과를 상술하면 다음과 같다.The urethane sheet (u) stretched on the surface of the relatively thin natural leather (ℓ) is bonded with an adhesive (1), and about 1-3 sheets of nylon waterproof cloth (n) is attached to the back of the natural leather (ℓ). 2) by inserting between the cotton bumpo (c) and the natural leather (ℓ) was laminated with a soccer ball fabric of a certain thickness (h). When described in detail the effect of the football fabrics of the present invention configured as described above.

천연피혁(ℓ)의 표면에는 연신된 우레탄시이트(u)가 접합되어 있어, 종래의 코팅된 우레탄수지층(u')(u")보다 그 두께를 더 두껍고 균일하게 할 수 있어 종래 것보다 외관이 좋으면서도 사용도중 쉬이 박리되거나 마모되지 않아 공의 수명을 오래 갈수있게 할 수 있으며 또한 따라서 그만큼 오랫동안 방수효과를 기할수 있다.Stretched urethane sheet (u) is bonded to the surface of natural leather (ℓ), and its thickness can be made thicker and more uniform than conventional coated urethane resin layer (u ') (u "). This is good and can not be easily peeled off or worn during use, so that the life of the ball can be extended.

또한 천연피혁(ℓ)의 이면에는 면범포지(綿帆布地)(c)와의 사이에 나일론방수포(n)가 삽착되어 있어 면범포지(c)로 부터 흡기가 천연피혁(ℓ)으로 전달됨을 방지할수가 있어 그만큼 공의 수명을 오래 지속시킬수 있음과 동시에 전체면에서 신축성이 큰 천연피혁(ℓ)가 차지하는 비중이 종래의 경우에 비하여 적으므로(이는 종래 비교적 두꺼운 천연피혁(ℓ)의 두께를 나일론방수포(n)의 사용으로 그만큼 얇아지게 하기 때문이며 본 고안에서 비교적 두께가 얇은 천연피혁(ℓ)이라고 표현한 이유는 이때문임) 원단은 그만큼 신축변화가 없어 공의 품질을 그만큼 향상시킬 수가 있다. 다만, 본 고안의 원단의 전체두께(h)나 종래의 원단의 전체두께(h)는 동일하며 본 고안에서 사용하는 천연피혁(ℓ)의 두께에 따라서 그 이면에 접합시키는 나일론방수포(n)의 매수를 결정하는 바, 통상 천연피혁의 성질로 보아 나일론방수포의 사용매수가 3매를 초과하는 경우에는 원단의 기준두께를 초과하게 된다.In addition, a nylon waterproof cloth (n) is inserted between the cotton leather cloth (c) and the back surface of the natural leather (ℓ) to prevent the intake air from the cotton leather cloth (c) to the natural leather (ℓ). Since the life span of the ball can be maintained for a long time, the proportion of natural leather (ℓ), which has a high elasticity, is less than that of the conventional case. This is because the use of (n) makes it thinner and the reason why it is expressed in this invention as a relatively thin natural leather (ℓ) is because of this.) The fabric has no elastic change so that the quality of the ball can be improved accordingly. However, the total thickness (h) of the fabric of the present invention or the total thickness (h) of the conventional fabric is the same and according to the thickness of the natural leather (ℓ) used in the present invention of the nylon waterproof cloth (n) bonded to the back When the number of sheets used is determined by the nature of natural leather, when the number of sheets of nylon waterproof cloth exceeds 3 sheets, the standard thickness of the fabric is exceeded.

또한 본 고안에서 사용하는 우레탄시이트(u)는 순수한 우레탄필름을 연신한 것이라도 좋고 그 이면에 폴리에스터섬유등 합성섬유로된 부직포를 보강시킨 것이라도 좋다.In addition, the urethane sheet (u) used by this invention may be what extended | stretched the pure urethane film, or what reinforced the nonwoven fabric of synthetic fiber, such as polyester fiber, on the back surface.

이상과 같이 본 고안의 축구공용원단은 종래의 것에 비하여 그 수명을 오래 지속시킬 수 있음과 동시에 기타 외관이나 품질을 향상시킬 수 있는 이점이 있다.As described above, the soccer composite fabric of the present invention has the advantage of being able to maintain its long life and improve other appearances and quality as compared with the conventional one.
