In order to explore an objective test to evaluate shape memory function for PTT fabrics, we developed a rectangular groove forming device and a sliding block stroking device and put forward the test method and evaluation method.In the experiment, we chose PTT, PTT/PET and common material fabrics, such as cotton, silk, viscose, PET and Milk/Tencel, for the plastic forming qualitative test.The results showed that PTT, PTT/PET fabric and PET fabric with high compact structure has plasticity.Further quantitative comparison of plastic forming and shape recovery of plastic fabrics was tested.Results showed that the CV values of the shape memory function testing method of the designing fabrics is less than 5%, which means that this method has a good reference value.Choosing PTT fiber as warp and weft yarn, right warp and weft density and compact structure, such as plain weave, can improve fabric shape plasticity and shape recovery performance.Among the three factors of materials, structure and compactness, the fiber material is the most important, and the PTT fiber is obviously superior to other fibers.
