Abstract: To address interfacial degradation of thermoplastic polyurethane (TPU) adhesives for cotton fabrics during water exposure in applications such as sports footwear and outdoor equipment, a polyester/polyether‐type TPU blending strategy was developed. Maleic anhydride‐grafted TPU (TPU‐g‐MAH) was employed as a compatibilizer to construct a ternary system of polyester‐type TPU/TPU‐g‐MAH/polyether‐type TPU. The compatibilizer promoted hydrogen bonding among hard segments and formed a physical cross‐linked network, facilitating uniform dispersion of polyether segments and improving phase compatibility. This synergistic structure effectively suppressed water penetration and enhanced hydrolytic stability. The optimized formulation (mass ratio: 90/0.5/10) exhibited a tensile strength of 14.58 MPa, elongation at break of 1584%, and T‐peel strength of 12.68 N/mm. After 96 h of water immersion, water absorption was only 1.25%, and the tensile and peel strength retentions reached 91.02% and 88.56%, respectively. These results demonstrate that the TPU‐g‐MAH‐modified polyester/polyether TPU system provides a robust approach to develop water‐resistant, high‐toughness TPUs for textile bonding and outdoor functional materials. Summary: Blending polyether‐type TPU with polyester‐type TPU enhances the material's stability in water.The compatibility of polyester/polyether TPU is enhanced by using TPU‐g‐MAH.The modified TPU composites retain over 88% tensile and T‐peel strength after 96 h immersion.The modified TPU composites show a water absorption of only 1.25% after 96 h immersion.
