Abstract:

To improve the bending rigidity of polyester filament lining fabric, the influences of fabric structure on the bending rigidity during dyeing and finishing were studied. Experiments to simulate the dyeing and finishing processes were undertaken, process conditions were varied so that structural change of the fabric as affected by different shrinkages and weight reduction ratio was determined, and the data concerning the bending rigidity versus fabric structure change were obtained. The relationship between fabric structure parameters and bending rigidity is established by the non-linear regression analysis. The bending rigidity is predicted by BP neural network based on the change in fabric structural parameter during dyeing and finishing, and the prediction precision is rather high.
