◼️ Chemical-bonding nonwoven fabric
Process Flow: The emulsion or solution of chemical adhesive is applied to the fiber web. The application method can be dipping, spraying, foaming, etc., and then the fiber web is heated to achieve the purpose of bonding and reinforcement.
Features: It is relatively fluffy, soft and has good water absorption.
Application: Lining, Medical and health care, disposable products , blinds …
◼️ Thermal-carlendaring nonwoven fabric
Application: production of baby diapers and sanitary napkin covering materials, ointment base fabrics, tape base fabrics, ABD pad covering materials, clothing linings, masks, etc.
Weight: usually 15~80g/m2.
Features: surface bonding hot rolling surface is relatively smooth, point bonding hot rolling is relatively fluffy.
◼️ Air-throungh bonding nonwoven fabric
Working principle: Hot air passes through the fiber web vertically, causing the low-melting-point fiber part or high-molecular polymer powder to melt rapidly, and the fiber web is solidified after cooling. Gram weight: usually 15~400g/m2.
Features: fluffy, soft, good elasticity, stable fiber web structure
Application: production of baby diapers and sanitary napkin covering materials and guide layers, ABD pad covering materials, filter materials and composite reinforcement materials, etc.
