牛仔坯布参数对水洗缩率的影响研究
Research on influences of denim fabric parameters on washing shrinkage rate
摘要
Abstract
In order to regulate and optimize the quality and stability of denim fabric and end products,various denim fabrics have been prepared using yarns with different counts and spinning methods by changing the warp/weft density and fabric pattern structure.The influences of yarn and fabric parameters in denim fabric on wash-ing shrinkage rate were investigated,and the washing shrinkage rate was simulated and predicted by BP neural network.The results show that yarn count,fabric density,warp/weft tightness,and spinning methods have a sig-nificant impact on the washing shrinkage rate.The dimensional changes of yarns and fabrics after washing can be considered from the aspects of yarn crimp and internal stress relaxation.The BP neural network model has shown potential in predicting the washing shrinkage rate of denim fabric.Although the prediction accuracy needs to be improved without considering the fabric structure,the prediction accuracy can reach 89.91%(warp)and 89.55%(weft)under the 3/1 right twill structure.This provides the theoretical basis for adjusting the produc-tion process of denim fabric and it is of great significance for improving the quality and stability of denim prod-ucts.关键词
