Description

축구공 언더지의 제조방법Manufacturing method of soccer ball under

본 발명은 축구공 언더지의 제조방법에 관한 것이다.The present invention relates to a method for producing a soccer ball underlay.

종래, 축구공 언더지는 주로 직물(옷감)로 만들었으며, 축구공을 만들때, 인장강도(Tensile Strength)와 인열강도(Elongation)가 약해서 공의 외관상 불균형이 일어나고, 공을 꿰멜때, 마창(터짐)이 일어나며, 탄력성도 적은 문제가 있었다.Conventionally, the soccer ball underlay is mainly made of fabric (cloth), when making the soccer ball, the tension and tear strength (Elongation) is weak due to the appearance of the ball unevenness, sew (when stitching) Rupture) occurs, there was also a problem of less elasticity.

이에 본 발명자는 종래의 축구공 언더지가 갖는 문제점을 해소시키기 위해 예의 연구를 거듭하여 본 발명에 이르게 되었다.In order to solve the problems of the conventional soccer ball under this, the present inventors earnestly studied and led to the present invention.

본 발명은 인장강도와 신장율이 우수한 축구공 언더지의 제조방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a method for producing a soccer ball under excellent tensile strength and elongation.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명은 3데니어의 폴리에스테르 섬유와 4데니어의 저용융 섬유를 9 : 1 내지 7 : 3의 비율로 혼방 및 개면하고, 개면된 섬유를 일정 두께의 랩으로 성형한 후에, 다단계로 매트지와 함께 펀칭을 하고, 180℃ 내지 200℃의 온도하에서 건조시킨 후 천연 고무 라텍스를 함침시켜서 제조하는 축구공 언더지의 제조방법인 것이다.The present invention blends and remodels 3 denier polyester fibers and 4 denier low melt fibers at a ratio of 9: 1 to 7: 3, and after forming the opened fibers into a wrap of a predetermined thickness, Punching together, and dried at a temperature of 180 ℃ to 200 ℃ it is a method of manufacturing a soccer ball under the impregnation of natural rubber latex.

이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명은 폴리에스테르 섬유와 저용융 섬유를 사용하여 특수 열처리를 한 후에 천연 고무 라텍스를 함침시켜서 축구공 언더지를 제조하는 방법으로서, 먼저, 3데니어의 폴레에스테르 섬유와 4데니어의 저용융 섬유를 9 : 1 내지 7 : 3의 비율로 혼방을 하고, 혼방한 섬유를 개면기를 이용하여 올올이 풀어 헤쳐서 개면한다.The present invention is a method for producing a soccer ball under the impregnated with natural rubber latex after a special heat treatment using a polyester fiber and a low melt fiber, firstly, a three-denier polyester fiber and a four-denier low-melt fiber 9 The mixture is blended at a ratio of 1: 1 to 7: 3, and the mixed fibers are unwrapped and opened by using a opener.

이때, 개면기에서 완전히 풀어 헤쳐지지 않은 섬유를 추가로 재차 개면할 수도 있다.At this time, the fiber that has not been completely released from the opener may be further opened again.

이렇게 개면된 혼방섬유를 카드기에 투입하여 일정한 두께로 랩(lap)을 형성한 후에 랩을 여러두께로 다시 포갠 후에 섬유끼리 서로 엉켜서 분리되지 않게 하기 위해 1 내지 3차에 걸쳐 펀칭을 한다.After the thus-formed blended fiber is put into a carding machine, a lap is formed to a certain thickness, and the lap is re-folded to several thicknesses, and then punched for 1 to 3 times so that the fibers are not entangled with each other.

이때, 매트지를 상하로 투입하여 함께 펀칭을 할 수도 있다.At this time, it may be punched together by putting the mat up and down.

상기와 같이 펀칭과정을 완료한 후에는 섬유원단을 180℃ 내지 200℃ 사이의 온도로 열을 가하여 원단을 건조(열처리)시킨 후에 천연고무 라텍스를 함침시켜서 본 발명에 따른 축구공 언더지를 제조한다.After completing the punching process as described above to heat the fabric at a temperature between 180 ℃ to 200 ℃ to dry the fabric (heat treatment) and then impregnated natural rubber latex to produce a soccer ball under the present invention.

만일, 상기 온도범위를 벗어나서 열처리를 하게 되면 최종적으로 얻어지는 언더지가 질겨지지 않아 축구공의 마모율을 높히게 된다.If the heat treatment is performed outside the temperature range, the resulting undershoot does not become tough and increases the wear rate of the soccer ball.

본 발명에 의하여 제조된 축구공 언더지는 폴리에스테르 섬유와 저용융 섬유를 사용하여 특수 열처리를 한 후에 천연고무 라텍스를 함침시켜서 제조하기 때문에 폴리에스테르 특성에다 고무의 특성을 혼합시킨 것으로 종래의 축구공 언더지로 사용된 직물류 보다 더 질기고, 단단한 특징이 있다.The soccer ball under manufactured according to the present invention is manufactured by impregnating natural rubber latex after special heat treatment using polyester fiber and low melt fiber, and thus mixing the properties of rubber with polyester properties. It is tougher and harder than the fabrics used for the paper.

또한, 본 발명에 의한 축구공 언더지는 축구공을 꿰멜때, 공의 외관상 불균형이 일어나지 않게 하고, 마창(터짐)이 거의 없게 되며, 공의 탄력성도 뛰어나게 하면서 마모율은 상단히 낮게 해주는 특징이 있다. 이로인하여 축구공 제작시의 작업성도 좋아지게 되고, 불량율도 거의 발생하지 않게 되는 장점이 있다.In addition, the soccer ball under the present invention is characterized in that when the soccer ball is sewn, the imbalance in the appearance of the ball does not occur, there is almost no swelling (burst), and the wear rate is extremely low while also excellent in the elasticity of the ball. This improves the workability when manufacturing the soccer ball, there is an advantage that the defect rate hardly occurs.

본 발명에 따라 제조한 축구공 언더지(두께 1.76mm, 중량 850g/㎡)와 종래의 언더지(두께 2.26mm, 중량 667.5g/㎡)와의 경도, 인장강도 및 신장율을 4차례에 걸쳐 경사방향과 위사방향으로 구분하여 비교실험한 결과는 다음 표 1와 같다.Inclined direction of the hardness, tensile strength and elongation of the soccer ball underneath prepared according to the present invention (thickness 1.76 mm, weight 850 g / m 2) and the conventional under (thickness 2.26 mm, weight 667.5 g / m 2) over four times The result of the comparative experiment divided into and weft direction is shown in Table 1 below.

상기 표 1에 나타낸 바와 같이, 본 발명에 따른 언더지의 물성은 경사 방향에서 평균강도가 0.153이고, 평균인장강도는 660이며, 평균신장율은 66인 반면에 종래예는 평균강도가 0.216이고, 평균인장강도 442이며, 평균신장율은 98이다. 또 위사방향으로는 평균경도가 0.173이고, 평균인장강도는 558이며, 평균신장율은 60인 반면에 종래에는 평균경도가 0.22이고, 평균인장강도는 294이며, 평균신장율은 107인 점으로 보아, 본 발명의 언더지가 물성면에서 휠씬 우수함을 알 수 있다.As shown in Table 1, the physical properties of the under according to the present invention has an average strength of 0.153 in the inclined direction, the average tensile strength is 660, the average elongation is 66, while the conventional example has an average strength of 0.216, the average tensile steel 442, the average elongation rate is 98. In the weft direction, the average hardness is 0.173, the average tensile strength is 558, and the average elongation is 60, whereas the average hardness is 0.22, the average tensile strength is 294, and the average elongation is 107. It can be seen that the under of the invention is much superior in terms of physical properties.

또한, 이러한 언더지를 사용하여 직접 축구공을 제조하고, 이 축구공을 2000회와 5000회에 걸쳐 락테스트(Racktest) 후에 공의 마모율, 팽창율 및 라운드니스(roundness) 결과를 다음 표 3에 나타내었다. 여기서 종래의 공으로는 아디다스사에서 만든 축구공을 사용하였으며, 본 발명의 축구공과 아디다스 축구공의 물리적 특성의 사양은 다음 표 2와 같다.In addition, the ball was directly manufactured using the underlay, and the wear rate, the expansion ratio, and the roundness of the ball after the rack test for 2,000 and 5000 times are shown in Table 3 below. . Here, the conventional ball was used as a soccer ball made by Adidas, the specifications of the physical properties of the soccer ball and the Adidas soccer ball of the present invention are shown in Table 2 below.

상기 표 3에 따르면, 본 발명의 언더지를 이용하여 제작한 축구공의 종래의 축구공에 비해 마모율과 팽창율 면에서 휠씬 우수함을 알 수 있다.According to Table 3, it can be seen that in terms of wear rate and expansion rate is much superior to the conventional soccer ball of the soccer ball produced using the under of the present invention.

본 발명에 따른 축구공 언더지는 럭비공이나 족구공의 언더지로도 유용하며, 상기와 같은 증진효과로 인해 경기력을 향상시키는데 도움을 주게 된다.The soccer ball under the present invention is also useful as an underlay of a rugby ball or foot ball, and helps to improve the game performance due to the above-described enhancement effect.
