纯棉弹力织物及其弹性伸长率的预测

Elastic Cotton Fabric and Prophecy of Elastic Extension

建立以经纬纱支、经纬密度描述纯棉弹力织物中螺旋状纱线结构的数学模型;导出织物弹性与经纬纱支及经纬密度问的理论关系式、用于织物弹性大小的预测及确定有关的工艺参数。

The mathematical model to describe fabric spiral yarn structure based on diameter and density of warp and weft is established during researching elastic cotton yarn. Relation between fabric elasticity and diameter and density of warp and weft is obtained from the model. It can be used to prophesy the elasticity of fabric, and also the process parameters can be decided on according to expected elasticity. The theoretical prophecy is proved by test. Theoretical elasticity and value got from the test accord well with each other
