Title:
極細繊維生成方法及び生成装置
Document Type and Number:
Japanese Patent JP6425023
Kind Code:
B2
Abstract:
An ultrafine fiber production device has a first heating unit, a nozzle unit, a hot air heating unit, a hot air blowing unit, a second heating unit, and a fiber collecting unit. The first heating unit melts a thermoplastic resin. The nozzle unit discharges the thermoplastic resin melted by the first heating unit. The hot air blowing unit performs fiber forming by blowing high-temperature gas produced by the hot air heating unit to the melted thermoplastic resin discharged by the nozzle unit and by extending the thermoplastic resin. The second heating unit further heats, extends, and fines produced fibers. The fiber collecting unit collects the thermoplastic resin in a fibrous form which is fined by the second heating unit.
