Description

Films of high molecular weight Nylon 6 (I.V. =8.6-11.3 dL/g) were uniaxially drawn by a tensile force at 240°C, above the static melting temperature (>220°C) of the undrawn sample. Relations between drawing stress (δd) and structural development in the resultant drawn films were evaluated mainly by WAXD measurements and tensile tests. Both α and γ-crystals were formed in the drawn samples. The fraction of the α-crystals in the crystalline phases was dependent on the δd, the higher the δd, the higher was the fraction of α-crystals, leading to the increase of tensile modulus. In this work, the maximum of the δd was about 3.5 MPa. In this case, the fraction of the α-crystals in the crystalline phase was about 0.75. The fraction was increased further by a heat treatment under the high stress. By the annealing of the drawn samples, a part of the oriented amorphous chains and γ-crystals were transformed into α-crystals. As a result, the tensile modulus was increased up to 18.6 GPa.
