Dacron

Dacron is a brand name for a family of polyester fibers and fabrics based on polyethylene terephthalate (PET). It was developed by DuPont in the 1950s and has since become widely used in textiles and industrial applications. The Dacron line includes staple fibers and continuous filament yarns used alone or blended with other fibers.

Production and forms: Dacron fibers are produced by melt-spinning PET into filaments, which can be textured, drawn, or otherwise processed to achieve different strength and feel. These fibers are used in a broad range of products, from clothing and upholstery to carpets, ropes, and tire cords. Dacron is also employed in sailcloth because of its dimensional stability and UV resistance.

Properties: Polyester fibers like Dacron offer high tensile strength, good abrasion resistance, and strong wrinkle resistance. They have relatively low moisture regain, quick-drying, and excellent dye uptake for durable, bright color. Dacron fabrics typically maintain shape and resist stretching, though performance can vary with fiber grade and blending.

Applications: In consumer textiles such as apparel, home furnishings, and activewear, as well as in industrial uses including tire reinforcement, industrial yarns, and reinforced composites. Dacron is also used in some medical devices, notably vascular grafts and patches, where biocompatible polyester fibers provide structural support.

Brand and ownership: The Dacron brand is associated with Invista, a company with historical ties to DuPont, and the name is used globally across multiple PET-based fiber grades.

Care and safety: Dacron textiles are generally safe for everyday use. Care instructions depend on the specific product and textile blend, but excessive heat can damage or melt polyester fibers.
