Draw process is to improve mechanical properties of sheet with greater molecular orientation and the resulting greater strength. In some processes all the draw is introduced in on step, in a single-stage of feed and take-up rollers. This single-stage draw can result in sheet breakage. As the number of stages is increased, it is possible to keep each freespan and roller at a different temperature, in order to obtain the maximum molecular orientation in the sheet. Recently, more effective drawing process have been demanded to produce high-modulus and high-tensile nylon 6 sheet. In this study, we researched drawing process for improvement of mechanical property of nylon 6 sheet in a double-stage. Tensile strength, elongation of drawing nylon 6 sheets were examined.
