Beschreibung
Zusammenfassung:	PURPOSE:To obtain PVA-based sheath-core conjugate yarn having the number of cores in a specific range and excellent flushable properties, comprising a PVA-based polymer having a specific melting point as a sheath component and a fiber-forming polymer having a higher melting point than that of the sheath component polymer as a core component. CONSTITUTION:The objective yarn comprising a PVA-based polymer (e.g. PVA having 500-1,200 average polymerization degree and 50-98mol% saponification degree) having 90-140 deg.C melting point as a sheath component and a fiber-forming polymer (e.g. nylon 6 or polyethylene terephthalate) having >=20 deg.C higher melting point than that of the sheath component polymer as a core component and having 1-10cores.
