Beschreibung
Zusammenfassung:	A cylindrically shaped product having superior filtrability, water-permability, etc., a process for producing the same in a good efficiency, and a filter and a draining material using the same are provided, the cylindrically shaped product obtained by winding multi-component, conjugate spun-bonded long fibers, consisting of at least two components of a lower melting resin component and a higher melting resin component, the melting temperature difference therebetween being 10 DEG C. or higher, and cylindrically shaped product having been hot-melt-adhered by the lower melting resin component.
