Abstract

There is a significant Poisson effect for knitted fabric under tensile deformation. It is an important parameter for practical pattern design, numerical simulation of garment pressure distribution and garment dressing system. However, it is still difficult to measure the fabric Poisson ratio quickly and accurately. In this paper, a method for testing the elastic knitted fabric Poisson ratio and modulus was proposed based on orthotropic theory and strip biaxial tensile test. The fabric’s Poisson ratio and Young’s modulus are identified by linear regression, while the obtained values are validated by uniaxial tensile tests.
