The difference between spunbond non-woven fabric and hot air non-woven fabric

To judge the difference between spunbond nonwoven fabric and hot air nonwoven fabric, the first thing to understand is that spunbond is a non-woven fabric production process, which means that after polymer is extruded and stretched to form continuous filaments, the filaments Laying into a net, the fiber net is then subjected to a process of self-bonding, thermal bonding, chemical bonding or mechanical reinforcement. Hot air and hot-rolled non-woven fabrics are not spunbond processes. This process is a thermal bonding method, which is different from spunbonding.

Hot-air non-woven is a non-woven fabric formed by using hot air on drying equipment to penetrate the fiber web after the fiber is carded, so that it can be bonded by heating. It has the characteristics of high bulkiness, good elasticity, soft hand feeling, strong warmth retention, good air permeability and water permeability, but compared with the non-woven fabric produced by the spunbond process, the disadvantage of this process is lower strength and easy deformation. Therefore, the difference in the characteristics of the two processes creates different uses. Spunbond non-woven fabric is suitable for making non-woven handbags, with high strength and sufficient toughness. Hot air non-woven fabric is suitable for baby diapers, disposable tablecloths, filtering, sound insulation and shock absorption materials. Because of its good elasticity and high bulkiness. You can judge based on the toughness and strength of the non-woven fabric in the future.
