PET Polyester Fiber

PET Polyester

Versatile & Ideal for Coatings

History

PET is the most common thermoplastic polymer in the polyester family. The first US commercial polyester fiber production was completed in 1953 by DuPont™ under the name Dacron®. It is the same polymer resin utilized in the plastic bottle industry.

Composition
PET is produced in a melt-spun and drawing process. The three processes utilized in the production of PET fiber are polymerization, melt-spinning, and drawing or hot stretching the fibers based upon their elongation requirements.

Common Types & Deniers
High Tenacity
Standard Shrink
Low Shrink
Ultra-low shrink
Deniers: 50 - 3000
