Fundamental Relationship Between Extensibility of Stretch Fabric and It's Pressure

스트레치 직물의 재질특성에 따른 신장율과 압력과의 상관관계 연구

The objective of this research was to determine whether the pressure on the cylinder by stretch fabric could be related by the size of cylinder, the amount of extension, and the properties of the fabric. The results were as follows : 1. There were linear relationships between the pressure of the fabric exerts on the cylinder and percentage of extension of the fabric, the radius of the cylinder, the tensile stress of the fabric, and the bending and shearing properties of the fabric. 2. From the results above, 4 regression equations from which the pressure could be estimated were derived by regression analysis. The equations were as follows : 1) P=a/Rb 2) P=c＋ds 3) P=e＋fSt 4) P=g＋hB P : Pressure, R : Radius of cylinder, S : Percentage of Stretch, St : Tensile stress, B : Bending property.
