PURPOSE: To obtain synthetic leather with a volume feeling, by laminating a short-fiber web containing a low-melting synthetic fiber to nonwoven fabric consisting of filaments of synthetic fiber, heat-treating the laminate to bond each fiber, and applying a synthetic resin film to the short-fiber web side.
CONSTITUTION: Filaments of synthetic fiber such as polyester, etc. are accumulated to give web, which is sent to hot rolls in such a way that bulkiness will not decreas e excessively to give nonwoven fabric. Short-fiber web provided with proper crimp, consisting of synthetic, natural fibers, etc., wherein 5W30 wt.% (based on short-fiber web) low-melting synthetic fibers are blended and dispersed, is laminated to the nonwoven fabric, and needle punched to form an integrated sheet, which is heat-treated unde-r pressure-, so that the low- melting synthetic fibers are melted, each fiber is bonded to prevent fluff and to improve breaking strength. Then a synthetic resin film (e.g., vinyl chloride film) is applied to the short-fiber web side, to give synthetic leather such as vinyl chloride leather, etc., useful as a brief case, bag, etc., having a volume feeling and is firm.
