Hot-rolled bonding and hot-air bonding are the two main processing methods for thermal bonding reinforcement of non-woven fabrics.

Hot-rolled bonding and hot-air bonding, as the two core processes of non-woven thermal bonding reinforcement, each has distinct characteristics and application fields.

Hot rolling bonding is mainly through the action of hot roll and pressure, so that the non-woven fabric fibers produce melt bonding, so as to achieve a strong bonding effect. This method has the advantages of high bonding strength and high production efficiency, and is especially suitable for the production of non-woven products with large thickness and high density. However, due to the high temperature and high pressure required in the hot rolling process, it may cause certain damage to the fiber structure of the non-woven fabric, affecting its softness and air permeability.

In contrast, hot-air bonding is to use hot air to heat the non-woven fabric, so that the melting point of the fiber surface is melted and bonded to each other. This method causes less damage to the fibers and can maintain the original softness and air permeability of the non-woven fabric. At the same time, the hot air bonding also has the characteristics of simple operation and high flexibility, and the temperature and air volume of the hot air can be adjusted according to the needs to adapt to the production of different types and specifications of non-woven fabrics.

In general, hot-rolled bonding and hot-air bonding have their own advantages and applicable scenarios. When choosing a non-woven fabric thermal bonding reinforcement method, it is necessary to comprehensively consider the performance requirements and production conditions of the product to achieve the best processing effect.
