Title:
【発明の名称】環状繊維集積体の製造装置
Document Type and Number:
Japanese Patent JP2504170
Kind Code:
B2
Abstract:
An apparatus for producing annular fiber aggregate includes: a container including an inner cylinder and an outer cylinder disposed concentrically, whereby forming an upright cylindrical space between the inner cylinder and the outer cylinder; at leaset a pair of positive electrode and negative electrode disposed by turns and buried in the wall of the outer cylinder, parallely with respect to the axis of the upright cylindrical space; a filter member disposed at the lower portion of the upright cylindrical space; and a voltage applicator connected to the positive electrodes and the negative electrodes. Since the apparatus has the positive and negative electrodes buried in the wall of the outer cylinder, the fibers are hardly disturbed and lifted by the positive and negative electrodes even when the positive and negative electrodes are rotated relatively around the axis of the upright cylindrical space. Thus, a fiber aggregate can be obtained in which the fibers are oriented in the peripheral tangent direction uniformly and favorably, and the strength thereof in the direction perpendicular to the peripheral tangent direction has been further enhanced.
