Improved fibers are owned and trademarked by the company that produces them. Dacron is a registered trade name for a polyester fiber made by DuPont. Dacron is especially known for its durability, consistency, and quality. Dacron, unlike natural fibers, is hypoallergenic, non-absorbent, and mildew-resistant. The versatility of synthetic fibers as a whole has warranted them an important and well-deserved place in the textile industry.
