Abstract:

For the fiber uneven density problem of high-pile knitting fabric, a method for predicting the fiber mass and compensating the error between the predicted result and design was proposed in this paper. Fiber mass changing was studied from the  feeding into carding unit to the hooked by a needle. Furthermore, a fiber transfer model was built. The fiber mass error variance was set up as the indicator of evaluating high-pile knitting fabric quality for product evenness and accuracy. According to the working principle of the high pile circular knitting machine and its carding unit, a digital design system and its pattern data analysis algorithm were designed. Based on it, error compensation and knitting result visualization methods were proposed. Using this system, the prediction results can be displayed. A fabric design case result shows that after system compensated, the fiber mass error variance of fabric is reduced by 90.92%, showing the fabric improvement in knitting quality.
