Sorona polyester is a type of synthetic fiber developed by DuPont. It is made from renewable plant-based materials, specifically corn. Sorona polyester is known for its softness, durability, and stain resistance, making it a popular choice for a variety of textile applications including clothing, carpets, and upholstery. Additionally, it is considered more environmentally friendly than traditional petroleum-based polyester because it reduces reliance on fossil fuels and produces fewer greenhouse gas emissions during production.
