description	To provide a method for manufacturing molten resin that enables continuous operation when manufacturing resin fibers from molten resin and suppresses the occurrence of thread breakage when forming resin fibers.SOLUTION: The present invention relates to a method for manufacturing a molten resin in which a first resin and a second resin are melted in a kneading extruder, and A-B≥60°C is satisfied where the melting point of the first resin is A and the melting point of the second resin is B. When the total length of the kneading extruder from the raw material input position to the molten resin discharge position is L, the maximum temperature in the range from the raw material input position to L×0.286 in the kneading extruder is A+50 to A+120°C.SELECTED DRAWING: Figure 1 【課題】本発明は、溶融樹脂から樹脂繊維を製造する際の連続操業が可能であり、かつ樹脂繊維を形成する際の糸切れの発生を抑制し得る溶融樹脂の製造方法を提供することを課題とする。【解決手段】本発明は、第１の樹脂と、第２の樹脂とを混練押出機で溶融する溶融樹脂の製造方法であって、第１の樹脂の融点をＡとし、第２の樹脂の融点をＢとした場合、Ａ−Ｂ≧６０℃であり、混練押出機における原料投入位置から溶融樹脂排出位置の全長をＬとした場合、混練押出機の原料投入位置からＬ×０．２８６までの範囲の最高温度がＡ＋５０〜Ａ＋１２０℃である、溶融樹脂の製造方法に関する。【選択図】図１
