Lesson 07 : Polyester

Chemical Properties

Effect of alkalies: Polyester is resistant to mild alkalies but concentrated alkalies at high temperatures disintegrate the fibre.

Effect of acids: Polyester’s resistance to organic acids and mineral acids is good to excellent. Highly concentrated mineral acids disintegrate polyester fibres if exposed to high temperatures.

Effect of bleaches: Polyester is resistant to many household bleaches. It can safely be bleached without any deterioration. Polyesters are produced with optical brighteners which give permanent white color.
