Abstract: PROBLEM TO BE SOLVED: To produce a hollow fiber membrane effectively usable as a dehumidification membrane by a dry-wet method from imide materials soluble in an org. solvent. SOLUTION: The polyether imide-base dehumidification membrane is a hollow fiber membrane produced from a polyether imide-polyamide imide blend and the inner surface of the membrane is preferably coated with polyvinylpyrrolidone or a humectant is preferably impregnated into the inner surface. Unlike a hollow fiber membrane of polyether imide only, the polyether imide-base membrane can effectively suppress the formation of voids and has improved durability.

Abstract: PROBLEM TO BE SOLVED: To provide a dehumidifier developing excellent dehumidifying capacity even if a blow means low in supply capacity is utilized. SOLUTION: Air to be dehumidified is sent into the hollow interiors of hollow fiber membranes 11 opened to the end surface of a seal part 13 and dehumidified during the passage through the hollow interiors of the hollow fiber membranes by the theory of known membrane separation and the dehumidified air is discharged in a direction P3. On the other hand, dry air passed through an adsorbent housing part 2 to be dried by the adsorbent is sent into a hollow fiber membrane module 1 from an introducing port 15 and passed through the outside of the hollow fiber membranes to be discharged to the outside of the hollow fiber membrane module 1 from a discharge port.

Abstract: PROBLEM TO BE SOLVED: To enhance filtering performance by forming hollow fiber membranes in a crimped state and disposing them in a case member. SOLUTION: The hollow fiber membrane module 1 consists essentially of a housing case 2, hollow fiber membranes 4 and a sealing member 5 which seals the gap between each side face of the membranes 4 and a discharge hole. The hollow fiber membranes 4 are formed in a crimped state by twisting a simple yarn, a double or triple thread or a bundle of >=4, preferably about 5-10 threads and carrying out fixation by heating in water at 90-100 deg.C and perfect untwisting to obtain the crimped state. Since the crimped hollow fiber membranes 4 are disposed in the housing case 2, the contact area of the membranes 4 is reduced and a gap is ensured between the membranes. Filtering performance can be enhanced, the blocking of the gap between the membranes is suppressed and the service life of the hollow fiber membranes 4 can be prolonged.
