针织物在拉伸变形下存在明显的泊松效应。它是实际样板设计、服装压力分布数值模拟和服装修整系统的重要参数。然而，快速准确地测量织物泊松比仍然是一个难题。本文提出了一种基于正交各向异性理论和条形双轴拉伸试验的弹性针织物泊松比和模量测试方法。采用线性回归方法确定了织物的泊松比和杨氏模量，并通过单轴拉伸试验对所得值进行了验证。
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.
