  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 μm. 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.
