In order to reexamine the slight variations of crystallinity with drawing or annealing, the four different procedures for determination of crystallinity have been tried on the 10 kinds of nylon 6 fibers which were prepared by the same methods as in the previous reports. These procedures, except for the procedure used in the previous study, are Ruland's procedure, density and X-ray differencial intensity procedures. Although the absolute values obtained by the four procedures differ from each other, the tendencies of variation of crystallinity with drawing and annealing were confirmed to be substantially identical to that described in the previous reports. Also the k values obtained by Ruland's procedure were compared among the fibers prepared under different conditions to yield the information concerning the imperfection of crystal lattice.
