Evaluation of Engineering Performance of Wet-Laid Nonwoven Fabrics Using Three-Component Fiber Blending

In this study, polyarylate nonwoven fabrics were manufactured by a wet-laid process by using viscose rayon and amorphous PET fiber as binding fibers. The engineering performance was evaluated after calendering to obtain a compact structure. From the polyarylate wet-laid nonwoven fabrics, it was confirmed that polyarylate fiber and binding fibers were mixed evenly. Through calendering, the permeability and pore size of the wetlaid nonwoven fabrics were significantly reduced owing to the compact structure. The bending strength and tensile strength increased through calendering, but the tensile elongation decreased. From an analysis of the tensile properties, monolayer wet-laid nonwoven fabrics showed better evenness than multilayer wet-laid nonwoven fabrics. In addition, multilayer wet-laid nonwoven fabrics showed a higher anisotropy than monolayer wet-laid nonwoven fabrics.
