MANUFACTURING METHOD OF MELT-SPINNING TYPE NONWOVEN WEB AND NONWOVEN WEB PRODUCTS MANUFACTURED THEREBY

摘要

The present invention relates to a method for manufacturing a melt-spun nonwoven fabric and a microfiber nonwoven web produced therefrom. The present invention is a method for producing a melt-spun nonwoven fabric in which fibers melt-spun through a spinning nozzle in which a thermoplastic polymer includes at least one nozzle hole is collected with a high-speed air flow, wherein the melt-spun fibers are provided directly under the spinning nozzle when spinning. As it passes through the heater for local heating of the nozzle, it is instantaneously subjected to local high temperature heat treatment higher than the spinning temperature, thereby lowering the melt viscosity of the thermoplastic resin discharged from the nozzle hole and the elongation viscosity on the radiation without reducing the molecular weight, thereby reducing the fiber compared to the conventional spunbond nonwoven fabric. It is possible to provide a fine fiber nonwoven web.
