Studies of Hydroentangled Nonwoven Fabrics (II) Effect of Processing Parameters on Fiber Entanglement

Hydroentangled nonwovens are alternatively called water-jet 'entangled' or 'spunlace' nonwovens. The hydraulic entanglement system is new technique for consolidating individual fibers in a web by means of high pressure water without the need for binder or/and other supplementary treatment. In recent, this system has been very interested in the field of nonwoven industry, since hydroentangled nonwoven fabrics have the patterned structure similar to woven fabrics and keep soft and drape characteristics. In this study, hydroentangled nonwovens have been made with 100% rayon and 50% rayon/50% polyester blended web and produced by a newly designed nonwoven system with different processing parameters. The manufacturing factors considered are injecting height, feeding speed, and passage number. Effect of processing parameters on the breaking strength of nonwovens has been investigated and it is compared with the morphological structure of nonwovens, i.e., aperture size and fiber density.
