摘要： PURPOSE:To obtain a feather suitable for a futon or quilting, by passing a dispersion of the feather through a friction imparting body like a stone mill wherein one of the pair rotates, pulverizing the core part of the feather to separate the soft fiber part, and selecting and collecting the soft fiber. CONSTITUTION:A dispersion of feather in water is fed from the inlet into a treating apparatus having a grinding and crushing mechanism consisting of a friction imparting body wherein at least one of the pair rotates like a stone mill, and the core part of the feather is selectively pulverized in the region of the friction imparting body, preferably a gap of 0.1-5mm., to separate the soft fiber part, and then expelled from the outlet to select and collect the soft fiber part from the expelled water. Thus, the aimed feather can be obtained. The feather is preferably selected and collected by filtering the expelled water or utilizing the difference in settling speed of the stored expelled water. According to the method, only the fiber part or a mixture of a somewhat hard core part can be freely obtained. EFFECT:The feather of a land bird produced in a large amount from poultry farming is usable.

摘要： PURPOSE:A spinning dope is extruded as the sheath part and air is sent into the core part and they are introduced into a coagulation bath to produce said hollow fibers having a dense layer on the inner surface and high water-permeability and substance separability. CONSTITUTION:A spinning dope of a polymer having no less than 50 wt% acrylonitrile content and no less than 200 poise viscosity it extruded from the sheath part of sheath-core type conjugate sipinnerets and slightly pressurized (generally 0,3-50cm water column) air or inert gas is sent to the core part, thereby effecting wet spinning, Resulting films has the very thin dence layer, less than 1/3 the total thickness of the film layer, on the inner surface, substantially no pores of 100Angstrom or larger diameter, therefore they are excellent in ultrafiltration property.
