摘　　要：平纹机织物内部纱线的截面一直被业界视为某种固定的形态,但应用可视化技术发现,基于经典的双凸截面模型存在问题,即使用微积分思路解决问题过程中,发现纱线截面变化的规律。研究结果表明,无论是单层机织物还是多层机织物,其纱线截面均呈现多元性,而非单一形态。特别是对于接结多层纬纱的经纱,其截面沿纱线长度方向按凹凸交变的规律呈周期性变化。这一研究成果对"织物纱线恒定截面论"提出了异议,对研究纱线的真实截面形态及织物外观模拟具有参考价值。The cross-section of yarn of plain woven fabric has always been viewed as a regular shape by academe. Based on classical convex model, with visualization technology, problems in the classical model are found, i.e., when solving the problems with calculus, the nile of yarn cross-section deformation is found. The results show that the diversity of the yarn cross-section shape in both one-layer and multi-layer woven fabrics, instead of single one, especially for the warp binding multi-layer wefts, whose concave cross-section alternates with convex one periodically along lengthwise. The findings take exception to ＂invariant cross-section assumption＂ and have theoretical value and guidance for research on the real shape of yarns and the simulation of fabric appearance.
