ORIENTATION OF MOLECULAR GROUPS IN CROSS SECTION OF POLYAMIDE-6 FIBER BY INFRARED ATTENUATED TOTAL REFLECTION DICHROISM STUDIES*

Received Date: 1 July 1986

The polymer fiber usually possess typical uniaxial orientation. The molecular chains are symmetrically distributed around fiber axis. In this work, the orientation of molecular groups in the cross section of polyamide-6 fiber has been measured by using IR ATR method. The results indicated that the polyamide-6 fiber mainly contains α-crystalline form. The direction of hydrogen bonds of amide groups is predominately parallel with the surface in the cross section of the fiber.
