An Investigation on the Effect of Azeotropic Solvent Mixture Pretreatment of 67:33 PET/CO Blended Fabric and Yarn: Part 1

摘要

Polyester fibre shows a definitive hydrophobic character and a high degree of crystallanity, making it difficult to penetration of dyes. Dye penetration can be improved by pre-treating the fibre using solvents or by annealing. Solvents and solvent mixtures can bring out modification in the fibre structure. Polyester fibre shows a definitive hydrophobic character and a high degree of crystallanity, making it difficult to penetration of dyes. The present study was made with an aim to modify physico-chemical behaviour of the fabric and yarn samples under study. This was made with analytical techniques such as scanning electron microscopy, Fourier Transform Infra Red Spectroscopy, Differential Scanning Calorimetric and X-Ray Diffractometry. The pre-treatments have resulted in solvent induced crystallization of the fabric matrix causing phyico-chemical changes. There was no loss in strength of the treated materials.
