Abstract: The thermal and kinetic behaviors of the sheath and insulation material taken from the fire-retardant PVC cable have been investigated in the air atmosphere by using thermogravimetrical (TG) analysis method. The degrading activation energy (Ea) of the material were calculated through Kissinger and Flynn-Wall equations based on the TG and DTG curves. The results showed that there were three steps during the degrading process of the FR PVC cable sheath and insulation materials, and the degradation rate increased with the increase of the heating rate. The average activation energy of the sheath and insulation material obtained from Flynn-Wall equation were 118 kJ/mol and 134kJ/mol, respectively.

Abstract: The basic theoretical research on sheath dress pattern with elastic fabric has put forward higher requirements. In this paper, based on dressing in dynamic change, combining with the body extend measure, the change of the pattern's control parts' specification and detail parts' specification are studied, and a basic sheath dress pattern with elastic fabric based on dynamic change is established. The human body's dynamic and static data show that the parameter of detail parts specification has great changes, while the parameter of control parts' specification parameter has small changes. For body detail parts' specification and structure, the parts that have not great changes only solve the problem of the fabric elastic utilization to meet the needs of the state of tight dress. According to the positions that produce dynamic increment, combining wearing condition, fabric elastic utilization and dynamic parameter, to design detail specification and pattern to satisfy sheath condition and dynamic demand.
