Summary:PROBLEM TO BE SOLVED: To provide a crimped yarn having fusion characteristics that can provide a woven or a knitted fabric having a good stretch-ability as well as bulkiness and a soft feeling.SOLUTION: The uneven crimped yarn having fusion characteristics comprises core-sheath type filaments. A core component is composed of a polyester comprising mainly alkylene terephthalate units and having a melting point of 220°C or more. A sheath component is composed of a low-melting point co-polyester having a melting point lower than that of the polyester. The crimped yarn has unevenness of crimps in a longitudinal direction. 【課題】良好なストレッチ性を有しながら、嵩高性、ソフト感をも保持する織編物を得ることができる、融着特性を有する捲縮糸を提供する。【解決手段】芯鞘型フィラメントからなる捲縮糸であって、芯成分が、アルキレンテレフタレート単位を主体とし、融点が220℃以上のポリエステルで構成され、鞘成分が、前記ポリエステルより融点が低い低融点共重合ポリエステルで構成され、捲縮糸が長手方向に捲縮の斑を有することを特徴とする融着特性を有する斑捲縮糸。【選択図】図1
