Abstract

The effective thermal conductivity and air permeability of a multifilament polyester yarn used in sports T-shirts was investigated by computer modeling using finite element analysis. It has been shown that the number of fibers, the porosity of the yarn and the proportion of fibers in the volume fraction of the yarn have a direct effect on the effective thermal conductivity and air permeability of the multifilament yarn. It was found that with the increase in the number of fibers, the porosity of the yarn decreases linearly, while the volume fraction of the fibers increases, and thus the effective thermal conductivity increases. In addition, air permeability decreases exponentially.
聚酯复丝纱透气性和有效导热系数的有限元预测
采用有限元方法对涤纶复长丝运动t恤的有效导热系数和透气性进行了计算机模拟研究。研究表明,纤维的数量、纱线的孔隙率和纤维占纱线体积分数的比例对复合长丝的有效导热性和透气性有直接影响。研究发现,随着纤维数的增加,纱线的孔隙率线性降低,而纤维的体积分数增加,从而有效导热系数增加。此外,透气性呈指数下降。
