What is polyethylene terephthalate fiber?

polyethylene terephthalate (PET or PETE), a strong, stiff synthetic fibre and resin and a member of the polyester family of polymers. The stiffness of PET fibres makes them highly resistant to deformation, so they impart excellent resistance to wrinkling in fabrics.

What are PET States two properties?

Polyethylene terephthalate polyester (PETP) is a hard, stiff, strong, dimensionally stable material that absorbs very little water. It has good gas barrier properties and good chemical resistance except to alkalis (which hydrolyse it). Its crystallinity varies from amorphous to fairly high crystalline.

Why is polyethylene terephthalate bad?

It contains polyethylene terephthalate (PET or PETE or polyester). Harms: PET is known to leach antimony trioxide and phthalates. Both of these are dangerous to health. While antimony may contribute to cancer development, skin problems, menstrual and pregnancy issues, phthalates are endocrine disruptors.
