In addition, the double fabric of the present invention is not required to sew to simplify the manufacturing process of the final product can be made cheap manufacturing costs.
본 발명에 있어서, 접결부위의 단위길이당 공기배출량(ℓ/분·cm)은 공기압력을 조절하는 레규레이터, 유량계 및 압력계가 부착된 측정장치로 측정한다. 구체적으로 2.5KPa 압력의 공기를 재단된 이중직물의 층분리부분으로 주입시켜 재단된 이중직물이 완전히 부풀려지게 한 다음, 단위시간(1분) 당 재단된 이중직물을 빠져나가는 전체 공기량을 ℓ단위로 측정한 후, 이를 재단된 이중직물의 전체 접결길이(cm)로 나누어 접결부위의 단위길이당 공기배출량을 구한다.In the present invention, the air discharge amount (l / min · cm) per unit length of the connection part is measured by a measuring device equipped with a regulator, a flow meter, and a pressure gauge for adjusting the air pressure. Specifically, the air of 2.5 KPa pressure is injected into the cut layers of the cut double fabric to completely inflate the cut double fabric, and then the total amount of air that exits the cut double fabric per unit time (1 minute) in l units. After the measurement, divide it by the total stitching length (cm) of the cut double fabric to find the air emissions per unit length of the joint.
