摘要:
A hollow fiber membrane laminate that includes a plurality of hollow fiber membranes wound to form a plurality of layers in a cylinder shape. The hollow fiber membranes are wound around a central axis while reciprocating a feeding point of the hollow fiber membranes along a central axis. Hollow fiber membranes adjacent to each other in each respective layer are separated by a predetermined separation distance. A speed differential z is reduced for successive layers approaching an outer side of the cylinder to maintain the predetermined separation distance. The speed differential z has a value obtained by dividing a pitch of the hollow fiber membranes within a respective layer by a traverse reciprocating distance.
