一纬全显织物结构设计要素与其显色规律的关系

Relationship between design elements and color rendering law of one-weft shaded weaves

为充分利用一纬全显组织以提升和细化数码提花织物对图像色彩的仿真表现,系统分析了一纬全显组织在单层黑白织物中的显色规律与其设计要素之间的关系。通过对一纬全显组织的基础组织、组织点的过渡方向与增加速率等3方面设计要素的性质研究,结合织物色卡的织造与测色数据分析,论述了三要素对组织结构显色规律的影响程度和方式。结果表明:组织点过渡方向决定了一纬全显组织的主要显色特征;基础组织飞数值对不同组织点过渡方向一纬全显组织的显色影响差异明显;而组织点增加速率是控制织物整体明度值区间细分的参数,但不能决定明度值的变化走向。

In order to make full use of the one-weft shaded weaves to improve and refine the digital simulative jacquard fabric design,the relationship between the design elements of the shaded weaves and its color rendering law in the monochrome single-layer fabrics was analyzed. Basic weave,transition directions and increasing rate of interlacing points are three key design elements of the shaded weave structure. The influences of those three design elements on the color rendering law were analyzed by means of the studies of their properties and the color values of fabric specimens. The results proves that the transition directions of interlacing points decides the color rendering law of shaded weaves,the step number of basic weave plays different role in the law when the shaded weaves designed with different transition directions; and the increasing rate of interlacing point is a parameter that subdivides the lightness value range of fabric specimens,but it is incapable of deciding the variation of the lightness value.
