The Application of Hollow Segmented Pie Bicomponent Spunbond Hydro-Entangled Microfiber Nonwovens for Microfiber Synthetic Leather Apparel

The polyester/nylon 6 hollow segmented pie bicomponent spunbond hydro-entangled microfiber nonwoven (PET/PA6 HSBSYMNW) was prepared and used as a leather base to produce microfiber synthetic leather for apparel. The structure and properties of PET/PA6 HSBSYMNW were investigated. SEM analysis indicated the fiber diameter size was between 2.2∼5.5 μm. Its performance met the demand of nonwoven textiles for synthetic leather. The obtained microfiber synthetic leather was arranged in a four-layer configuration, and its air permeability, water vapor transmission rate (WVT), thermal insulation, and hand properties were better than commercial garment synthetic leathers with different leather bases. The method achieved a more environmentally-friendly and high-performance preparation of microfiber synthetic leather used for apparel.
