摘要: 针对纬纱疏密分布的机织物———疏密纬织物提出了一种织物纬密变化方式的分区段输入方法。该方法首先引入具有简单、确定且可预定义的纬密变化规律的简单纬密变化区段的概念,通过把织物的1个纬密变化单元分解成若干个简单纬密变化区段,解决了织物纬密变化方式的输入问题。根据上述方法编制了将织物的预期纬密变化方式输入织机控制系统的程序,预定义了若干种常用的纬密变化规律,给出了各变化规律的表达式;构建了1个布片长度范围内随布长变化的纬密函数,拟定了根据纬密函数确定各纬卷取量的计算方法。

Abstract: In view of the varied weft density of sparse-dense fabric,a sectional input of the weft distribution information is presented.The method first introduces the conception of simple weft distribution section in which the change pattern of weft density is simple,definite and can be predefined,and further divides a weft density variation unit into several simple weft distribution sections,thus solving the input problem of the information concerning the varied weft density.According to the above method,a software program is worked out,by which the desired weft distribution pattern of the fabric can be input into the loom control system.Several commonly used weft density variation rules are predefined,and the expression for each rule is given.Moreover,the weft density function which varies as the length within the range of a prescribed length of fabric is constructed,and the algorithm of determining the take-up value for each weft yarn according to the weft density function is given.
