Polyester is also called Dacron, and nylon is also called nylon; Polyester is firm and wrinkle free, while nylon is sturdy and wear-resistant; Polyester has high strength, good impact resistance, heat resistance, corrosion resistance, moth resistance, acid and alkali resistance, and good light resistance (second only to acrylic fiber). After 1000 hours of exposure to sunlight, it maintains a strength of 60-70%, has poor moisture absorption, is difficult to dye, is easy to wash and dry, and has good shape retention; The biggest advantage of nylon is its durability and wear resistance, making it the best choice.
