| titleOfInvention | Method for producing ultra-fine fiber nonwoven fabric or leather-like sheet substrate |
| abstract | An object of the present invention is to provide a production method for producing an ultrafine fiber nonwoven fabric or leather-like sheet base material capable of maintaining high productivity and safety and maintaining high quality stability. SOLUTION: A first step of producing a fiber web composed of sea-island fibers containing a sea component composed of a water-soluble thermoplastic polymer and an island component composed of a water-insoluble heat-shrinkable polymer, and laminating a plurality of fiber webs A second step of forming an entangled web by entanglement and a third step of forming a densified entangled web by heat treating the entangled web and shrinking the water-insoluble heat-shrinkable polymer And a fourth step of forming the ultrafine fiber nonwoven fabric by removing sea components from the sea-island fibers forming the densified entangled web, and the heat treatment of the third step is performed on the entangled web in the dry state. A method for producing an ultrafine fiber nonwoven fabric, which is a process of contacting hot air adjusted to a temperature and humidity in the range of a wet bulb temperature of 70 to 76 ° C and a dry bulb temperature of 90 to 120 ° C.
