Abstract:

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 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 accurac 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.

Key words: sweater, stitch structure, material consumption, forecasting system
