摘　　要：为了预测机织物的弹性伸长,以Pierce的织物结构模型为出发点,对机织物拉伸过程中单根经纬纱交织点处受力单元进行了理论分析,提出了织物在拉伸过程中的变形主要由弹性变形和几何变形组成的假设。并在这个假设的前提下,依据纱线静力平衡原理及动量矩守恒定理,结合其他弹性力学理论,分别建立了平纹织物和2/1斜纹织物拉伸—伸长的数学模型,并对所建立的数学模型进行了实验验证。Pierce's rigid-thread model of the woven fabric model has been employed as a starting point, the relationship among strengths which act on the interweave point of the individual warp and weft of fabrics during stretching has been dealt with. Based on the analysis of the Pierce's model, the Newton's law of motion, the law of conservation of momentum, and other mechanical theories, the conclusion that the deformation of fabrics is composed of elastic deformation and geometric deformation has been achieved. And according to the law of equilibrium, the mathematical models for calculating the load -extntion of plain woven fabrics have been set up respectively.
