SPINNING NOZZLE AND PROCESS FOR PRODUCING FIBROUS BUNDLE
A spinning nozzle (1) which has a perforated part (2) in which ejection holes (3) have been arranged in a density as high as 600-1,200 holes/mm 2 . This process for producing a fibrous bundle comprises ejecting a spinning dope having a viscosity as measured at 50°C of 30-200 P from the ejection hole...

| description | A spinning nozzle (1) which has a perforated part (2) in which ejection holes (3) have been arranged in a density as high as 600-1,200 holes/mm 2 . This process for producing a fibrous bundle comprises ejecting a spinning dope having a viscosity as measured at 50°C of 30-200 P from the ejection holes (3) of the spinning nozzle (1) to produce a fibrous bundle. This fibrous bundle has a single-fiber fineness of 0.005-0.01 dtex. By the wet-process direct spinning, a mass of nanofibers which are stably uniform and continuous can be produced at a high efficiency. |
