Patent ID: 7951313

Claim:
A spinning apparatus comprising one or more exits for extruding liquid, which are capable of extruding a spinning liquid, and an exit for ejecting gas, which is located upstream of each of the exits for extruding liquid and is capable of ejecting a gas, wherein (1) the spinning apparatus comprises a columnar hollow for liquid Hl), in which the exit for extruding liquid forms one end of the columnar hollow for liquid, (2) the spinning apparatus comprises a columnar hollow for gas (Hg) of which one end is the exit for ejecting gas, (3) a virtual column for liquid (Hvl) which is extended from the columnar hollow for liquid (Hl) is located adjacent to a virtual column for gas (Hvg) which is extended from the columnar hollow for gas (Hg), (4) a central axis of an extruding direction in the columnar hollow for liquid (Hl) is parallel to a central axis of an ejecting direction in the columnar hollow for gas (Hg), and (5) when the columnar hollow for gas and the columnar hollow for liquid are cross-sectioned with a plane perpendicular to the central axis of the columnar hollow for gas, there exists only one straight line having the shortest distance between an outer boundary of the cross-section of the columnar hollow for gas (Hg) and an outer boundary of the cross-section of the columnar hollow for liquid (Hl).
