Dye-Induced Structural Changes and Mechanical Properties of Polyethylene Terephthalate Fibers

Abstract

Disperse dyes participate in the structural modifications of polyester fibers during dyeing. The change in the mechanical properties of the disperse-dyed polyester fibers over the blank-treated ones is, however, due to mechanical hindrance of the dye, which is dependent on the structure and the concentration of dye in the fiber. The dye-induced structural change has little or no effect on the mechanical properties.
