Process and device for manufacturing flat structure of fiber

繊維の面状構成体を製造する方法と装置

Abstract

(57)【要約】 【目的】 繊維不織布製フィルタ部材が長期間使用時に も良好な使用特性を持続するように製造する方法と装置 を提供する。 【構成】 2種類の材料を別個に溶融し、各溶融物が、 混合されることなく、分配装置により紡糸ロータ1の各 出口(4)グループに供給される。圧出された糸2は、 延伸され結合されて面状構成体にされ、後処理により摩 擦電気により帯電される。
PURPOSE: To provide a process and device for manufacturing a filter member from a fiber non-woven fabric to maintain a good utilizing characteristic even if the member is used for long period. CONSTITUTION: Two kinds of materials are separately melted and each melt is independently fed to each outlet (4) group of a spinning rotor 1 by means of a distributor device. An extruded fiber 2 is stretched and combined to be allowed to form a flat structure and then charged triboelectrically by an after treatment.
