At present, the more mainstream diaper surface materials on the market are: air-through non-woven fabric and anti-stick non-woven fabric. The surface layer is the part that is in direct contact with the human skin, so it is required to be dry, comfortable and soft. Hot-air non-woven fabrics have the characteristics of fluffy, soft, strong warmth retention, good air permeability and water permeability, and are more and more used in the surface layer of diapers. Anti-stick non-woven fabrics are not as soft and breathable as hot-air non-woven fabrics. With the improvement of anti-sticking non-woven fabric technology, the softness has improved, but the fluffy feeling is still not as good as hot-air non-woven fabric. In order to save costs, many merchants use anti-sticking non-woven fabrics as one of the main materials for the surface layer. Diapers made of hot-air non-woven fabrics will feel softer and more comfortable, while anti-stick non-woven fabrics will feel harder. Gently pull the surface layer of the diaper, the air-through non-woven fabric can easily pull out the silk, if it is a spun-bonded non-woven fabric, it is difficult to pull out the whole piece of silk.
