A New Drawing Technique for Nylon 6 by Reversible Plasticization with Iodine.

Abstract

A new method for drawing Nylon 6 has been developed using iodine as a reversible plasticizer. This is based on the ability of the alpha-crystals is fully transform to gamma-crystals by treatment with an aqueous KI3 solution. Drawing is performed on the intermediate Nylon 6-1 complex and iodine is subsequently removed with sodium thiosulfate to generate back a transparent, drawn Nylon 6. At 55 C, a 790% elongation has been obtained, considerably higher than previously reported for Nylon 6. A dynamic mechanical study of the undrawn complex showed an alpha-transition at 41-53 C. Above this temperature, it is rubbery and thus readily drawn. Originator supplied keywords include: Nylon 6; iodine; reversible plasticizer; drawing; Nylon 6-1 complex; Dynamic mechanical; X-ray diffraction; Crystallization; Monoclinic.
