摘要
为了分析毛衫生产中原料消耗的问题,将包含5种基本结构的毛衫为例并对其进行研究分析。通过在一定假设基础上,根据针床编织状态有关参数,经过分析推导,建立了毛衫常用组织结构编织模型图,进而推导出5种基本组织的线圈长度几何模型。并根据毛衫线圈个数与纱线线密度通过矩阵形式写出有关参数向量,建立毛衫消耗模型的表达式。根据所建模型,对包含基本组织结构的毛衫进行消耗面密度的预测,经实验认证表明,该模型达到对毛衫消耗面密度预测的误差在3%之内,验证了该模型的准确性。为毛衫企业生产用纱及生产成本核算提供有效的参考。
To analyze the question of raw materials consumption of knitted sweaters, sweaters with five basic structures were studied. On the basis of some assumptions, the loop models of common structures were established according to relevant parameters of knitting state of the needle bed, and then the length geometrical model of five basic structures were deduced. According to the number of coils and the linear densities of the five structures, the relevant parameter vectors were illustrated by mathematic matrix to conclude expressions of the sweater consumption model. With the proposed model, the weight of sweaters with basic structures can be predicted, and by the experimental results, the accuracy of model is verified to reach forecasting consumption error within 3%. With the proposed model, the weight of sweaters with basic structures can be predicted, which provides enterprises with references for cost.
