This document summarizes the characteristics and applications of 3D fabric. 3D fabric is a knitted textile that is three-dimensional, with an X-90 polyester structure in the middle to provide support and ventilation. It has properties like pressure distribution reduced by 50%, air permeability of 4800L/S.M2, easy washability and drying. Common applications of 3D fabric include housewares, baby products, healthcare supplies, sports protection, industrial uses like architecture, cars, and filtration. Examples given are 3D mattresses, pillows, cushions, baby items, army gear, car cushions, and air filters.
