Today we come to understand the diaper-the surface coating layer is also a non-woven fabric: the surface coating layer of the diaper consists of a hot air non-woven fabric and a water-repellent non-woven fabric.
Hot air non-woven fabric is a non-woven fabric formed by combing fibers and using hot air on drying equipment to penetrate the web and heat them to be bonded. Hot air adhesive products have high fluffiness, good elasticity, soft hand feeling, strong heat retention, good air permeability and water permeability, so the surface layer of general good diapers is made of hot air nonwoven fabric.
Hot air non-woven fabrics have higher production technology requirements and higher machine manufacturing costs, so diapers using hot air non-woven fabrics are generally more expensive. Although expensive, the baby will be more comfortable to wear.
