经编网眼织物设计的数学描述

Mathematical description on warp knitted mesh fabric design

经编网眼织物设计的研究都只是进行规律性概括,缺乏从数学角度进行描述。为此,对变化经平类网眼织物进行分类,并针对不同变化经平类网眼织物的设计方法进行探讨,建立了经编网眼织物穿经循环纵行数、组织循环横列数与垫纱组织、最大垫纱数码及基础组织针数等参数的数学关系,并在已知穿经循环针数、组织循环针数、移针针数等条件下,通过简单计算判断网眼织物分布类型以及网眼位置,为该类网眼织物设计提供理论参考,有效提高设计效率。

The research on warp-knitting design is focused on the regular summary, which is in shortage of the mathematical description. In this paper, the category of tricot stitch mesh fabric is classified and the design method of different kinds of tricot stitch mesh fabric is discussed. The mathematical relationship of design parameters such as drawing-in cycle count, structure cycle of horizontal longitudinal and mat yarn group, the largest yarn mesh code and the needle number of basic structure are studied. Based on the previous study, the distribution type of mesh fabric and the mesh position can be calculated according to the drawing-in cycle needle number, structure cycle needle number and the moved needle number. The present study can provide the theoretical basis for this kind of mesh fabric, and can improve the design efficiency of this mesh fabric as well.
