Abstract: A thermoplastic polyurethane resin suitable for melt spinning is formed from a reaction mixture via a polymerization reaction. The reaction mixture includes an isocyanate component and a polyol component. The polyol component includes a first polyol that has a first number average molecular weight and a second polyol that has a second number average molecular weight. The first number average molecular weight is between 1,000 g/mol and 1,500 g/mol, and the second number average molecular weight is between 2,500 g/mol and 3,000 g/mol. One resin component formed by the first polyol via the polymerization reaction is defined as a low melting point segment and correspondingly has a first melting point between 170° C. and 185° C. Another resin component formed by the second polyol via the polymerization reaction is defined as a high melting point segment and correspondingly has a second melting point between 195° C. and 210° C.
