摘要： PURPOSE: To obtain an acrylic hollow fiber having excellent bulkiness, compressive elasticity, water retentivity and heat insulating characteristic by setting the discharge angle of a raw liquid for spinning at 20W40° relative to a nozzle plane and spinning draft ratio at 0.9W1.5.
CONSTITUTION: The copolymer contg. 50W97wt% acrylonitrile is dissolved in an org. solvent such as DMF, DMA or DMSO to prepare the raw liquid for spinning. The shape of the spinning orifice is made into a triangular shape and the discharge angle is required to be set at 20W40° relative to the nozzle plane. The raw liquid is wet spun at 0.9W1.5 spinning draft ratio into a solidifying bath of an aq. solvent soln. of an acrylonitrile copolymer contg. ≥55wt% water. The spun fiber is in succession subjected to stretching, drying and relaxation treatment.

摘要： PURPOSE: A spinning dope of acrylonitrile-containing high shrinkage component and another dope of low shrinkage component are prepared and they are subjected to wet spinning of side-by-side conjugation, further drawing and heat treatment under relaxation to give the titled fiber having pilling-resistant and crimp-developing properties.
CONSTITUTION: (A) A spinning dope of high shrinkage component containing 85wt% or more acrilonitrile and (B) another spinning dope of low shrinkage component containing 85wt% or more acrilonitrile are prepared so that their viscosity becomes 50W100 poise, preferably 80W100 poise at 50°C. Then, both dopes are subjected to wet spinning of side-by-side conjugation and the resultant fiber is drawn at a ratio of 3.0W5.0 in hot water, dried and heat-treated under relaxed state in a saturated steam of 1.3W20kg/cm
2 G to give the objective fiber of 1.8W2.6g/d tensile strength, 20W35 crimp developing force calculated as a product of node strength and node elongation.
