A study on the relaxation behavior of fabric's crease recovery angle

On the basis of Viscoelasticity Theory of textile materials, the Maxwell's Model, Kalvin Paunting Model and Burger's model were analyzed in the paper. The regression equation of the strain relaxation curve was established and the experiments verify that the crease recovery angle can be predicted by the regression equation of Burger's model. The relaxation behavior of crease recovery angle varying with time was according to the creep‐relaxation equation.
