Some Problems in Drawing and Texturing of Vidlon Polycaproamide Fibres

  • Published:
Fibre Chemistry Aims and scope

Abstract

The nature and causes of separation of “white powder” in drawing and accumulation of deposits on machine chamber walls in texturing of Vidlon polycaproamide fibres are investigated. It was found that the quality of the titanium dioxide suspension and the oiling agent significantly affect separation of powder and passage of the fibre in drawing. Thermooxidative and thermal and mechanical degradation processes in the polymer determine the structure of the fibres and their behavior in drawing and texturing. The amount of “white powder” separated is a function of the moisture content of the as-spun fibres and the climatic conditions in winding, conditioning, and drawing. The concentration of cross-links in the polymer and inorganic elements on the surface of the fibres and the amount of “white powder” and deposits on the walls of texturing machine chambers are closely correlated with their passability in drawing.
