  Abstract

In this study, we investigated the effects of calendaring temperature and drawing process conditions on the physical properties of melt-blown polypropylene (PP) nonwovens. To control the form and physical characteristics of the nonwovens, a laminator was employed for the calendaring process, which enhanced the nonwoven properties through uniform heat and pressure distribution. By adjusting the calendaring temperature and drawing ratios, we manufactured nonwovens with varying thicknesses, fiber diameters, tensile strengths, elongations, and air permeabilities. The tensile strength and elongation of the nonwovens were significantly improved after the calendaring and drawing processes, particularly at higher temperatures and drawing ratios. However, excessive calendaring temperatures led to fiber film formation and structural damage, resulting in decreased tensile strength. Additionally, the density of the nonwovens increased post-processing, reducing air permeability. SEM analysis confirmed increased fiber diameters and some degree of film formation in higher temperature cases. Overall, our findings indicate that selecting appropriate calendaring temperatures and drawing ratios can significantly enhance the tensile strength and elongation of melt-blown nonwovens. These improvements in mechanical properties can contribute to the production of customized nonwovens that meet various industrial demands.
