Title: Production of conjugate hollow-fiber membrane
Inventor: KAMO JUN
IPC: D01D5/24
Filed: 1990-04-11
Abstract: PURPOSE:To stably and easily produce the composite hollow-fiber membrane having a thin separation layer without any defect being generated by applying a first-stage relaxation heat setting to a molten, shaped and undrawn hollow fiber under specified conditions and then applying a second-stage relaxation heat setting. CONSTITUTION:A conjugate hollow-fiber membrane in which a separation layer A and a porous layer B are alternately laminated and with the inner and outer surfaces consisting of the layer B is produced by melting, shaping and drawing. The molten, shaped and undrawn hollow fiber is annealed at a temperature of 120-10 deg.C lower than the m.p. TmB of a reinforcing-layer polymer B', cold- drawn by 1.1-6.0 times below the crystal diffusion temp. of the polymer B' and then subjected to a first-stage relaxation heat setting at a temp. between (TmB-20 deg.C) and (TmB-90 deg.C) at 100% or <=50% of the elongation in cold rolling. The fiber is further subjected to a second-stage relaxation heat setting at <=(TmB-10 deg.C) and at a temp. identical to or below the first-stage temp. at 100% or <=70% of the elongation after the first-stage relaxation heat setting.

Filed: 1981-06-20
Abstract: PURPOSE:To estimate the upper limit of the cladding speed of a cladding mateial that assumes an unknown liquid state by measuring the relations between the shearing rates and shearing stresses of a cladding material for comparison and a cladding material for measurement by a viscosimeter. CONSTITUTION:The relations between the shearing rates and shearing stresses of a cladding material for comparison which assumes a liquid state and of which the upper limit of a cladding speed permitting the cladding of a uniform film thickness on optical fibers is known are beforehand measured by a viscosimeter. The relations between the shearing speeds and shearing stresses of a cladding material for measurement that assumes a liquid state under the same conditions as these are measured and the ratio of the shearing speed at the max. value of the shearing stresses of the cladding material for comparison and that of the cladding material for measurement is determined. The value obtd. by multiplying this ratio by the upper limit of the cladding speed of the cladding material for comparison is estimated as the upper limit of the cladding speed at which the cladding of a uniform film thickness can be formed by the cladding material for measurement.
