Abstract

Bicomponent nonwoven fabric was developed by using a melt-blown process to replace a Gore-Tex membrane with water repellency and vapor permeability in outdoor clothing. In this research, bicomponent meltblown spinning by using a S/S (side-by-side) type nozzle was used for nonwoven with a small fiber diameter, water repellency, and water vapor permeability. Vistamaxx with good adhesion was mixed with VMPP (Peroxide/PP match batch chip, Manntek Co.) as a viscosity control material to increase the melt flow index (MFI) for a small diameter of the fiber. In addition, polypropylene (PP) was used by stabilizing the viscosity of the nonwoven. In the results, the average diameter of the fiber was approximately $2.15-2.52{\mu}m$. The diameter of the fiber was decreased by increasing the melt-spinning temperature and air flow pressure. We confirmed that the water repellency was improved by increasing the fiber density in a small-diameter process.
