Abstract

The effect of processing parameters on the structure and properties of hydroentangled nonwovens has been investigated for a newly designed nonwoven system, so called spunlace nonwoven process. Such a system is the nonwoven manufacturing process that empolys jets of wrote to entangle fibers and provides fabric integrity. Unlike the characteristics of general nonwovens produced by needle-punching, chemical bonding and thermal bonding methods, the outstanding characteristics of hydroentangled fabrics are soft, drape, comformability and relatively middle strength. In the present work, the hydroentangled fabric has been made with 100% ration and 50% rayon/50% polyester blended web and produced by this new system with different processing parameters such as pressure and injecting angle. We evaluated breaking stress of nonwoven fabrics and analysed to relate this property to nonwoven structure, i.e., aperture size, and aperture shape and fiber arrangement. Finally, an attempt is made to establish 'process-structure-property' relationship model to help engineering spunlace nonwovens for specific end-uses and to make optimum condition for the new water-jet fiber entanglement system.
