Polyester fibers are used in a great many textile and industrial materials, their undesirable electrical advantage bring about disadvantages.
Direct polymerization of pyrrole on polyester fibers may provide useful tools for producing new conducting materials.
Polypyrrole cannot be directly processed, due to its intrinsically poor mechanical properties, therefore it generally used for coating other materials[5-7].
Direct polymerization of conductive conjugated polymers on polyester fibers may provide useful tools for producing new conducting materials which allow to forming a conductive layer on the fiber substrate[1-7].
As far as polyester fibers are used in a great many textile and industrial materials, their undesirable electrical advantage bring about disadvantages.

Fig.3 The FEM model For there are material nonlinearity, geometric nonlinearity and boundary conditions' nonlinear ,it has made some following settings:the dies are deemed as rigid body,and the shafts are deemed as plastic body,choose steel of 42CrMo2 as material,and the frictions between shafts and the dies are shear frictions,the temperature of the rolling is set as 1050°.

Hot rolled steel is a material made by heating at high temperature.
Tensile strength refers to the maximum resistance to uniform plastic deformation of the material.
Liu, Zhu and Cao[3] in order to carry out materials data deep-excavation in hot die steels and obtain the relationships among alloying elements, heat treatment parameters and materials properties, a 11×12×12×4 back-propagation (BP) artificial neural network (ANN) was set up.
