The difference between polyurethane pillow and polyester fiber pillow

1, the biggest advantages of polyester fiber are good wrinkle resistance and shape retention, high strength and elastic recovery. At present, domestic pillow cores, cushions and other products that need high resilience all use polyester fiber.

2. Polyurethane is a polymer containing carbamate groups in the main chain of macromolecules, which is called polyurethane. The biggest similarity with polyester fiber is that the product has strong elasticity, strong formability, fast rebound and is not easy to deform. Polyester is polyester, the scientific name is polyethylene terephthalate, short for polyester. It is best to use hollow cotton as a pillow. Pure polyester fiber is not good and its bulkiness is not enough. The hygroscopicity and breathability of natural fibers such as silk cotton and kapok are definitely better and more environmentally friendly.
