Breaking phenomenon in the successive biaxially drawing of Nylon 6 film with a higher deformation rate than 10, 000%/min is discussed based on the relation between the orientation state of hydrogen bonded sheets in the predrawn film and the formation of kink band by the secondary drawing. Consequently, it has been found that a uniaxially oriented structure of hydrogen bonded sheets of Nylon 6 can be formed in the predrawn film by blending 5-20wt% of poly (m-xylylene adipamide) and is most effective to decrease the number of breaking times during secondary drawing. Based on the above information, the industrial production of Nylon 6 film by the successive biaxially drawing method has been realized.
