织物镜面反射光分布曲线的模拟计算

提出了一个较为接近实际的织物结构模型。结合织物组织结构因素对织物的镜面反射光分布曲线进行了模拟计算，从理论上证明了织物组织、经纬密度、屈曲波高、纱线长短轴之比、纤维折射率以及入射角等因素都对镜面反射光的分布具有较大影响。

Simulation on the goniophotometric curves of thespecularly reflected light for woven fabrics

Simulation on goniophotometric curves of fabrics was made witha new model, which closely correlates with the actual fabric construction.In the new model,an elliptical cross section of the yarn with a ratio 1/k of the major to minor axis is assumed.The separation and bdnding factors of the yarn are also considered.The filaments in the yarn surface are conceived to behave as narrow elliptic columns with various length of minor axis that are distributed on an elliptical curve as the luminous flux applied parallel to the filaments of the yarn.Calculation is carried out on the basis of the infinitesimal surfaces of the fabric were specular reflection.It can be found that the weave,separation and bending factor of the yarn,the ratio of the major to minor axis of the yarn cross section,refractive index of the fiber and incident angle of the light have important effects on the goniophotmetric curve.
