摘要： The present disclosure relates to a thermoplastic fiber web structure (2a, 2b, 2c, 2d), which forms a support structure through fiber filaments (21a, 21h, 21i, 21k, 21l, 21m, 21n, 21q) that are melt-bonded together, the fiber filaments being formed from a thermoplastic elastomer material. The present disclosure further relates to an automobile interior part comprising a thermoplastic fiber web structure as described above and a sleeve and/or fabric (1a, 1b, 1c, 1d) fastened to the thermoplastic fiber web structure. The thermoplastic fiber web structure forms a support structure by melt extrusion of a thermoplastic elastomer material into a three-dimensional network structure, which has high resilience and recyclability. The automobile interior part, at the same time of ensuring support and comfort, achieves environmental protection, breathability and light weight. In particular, the thermoplastic material is subjected to a physical reaction rather than a chemical reaction during the melt extrusion process, so that the stability in the preparation process is better, and the product can be smoothly and controllably made. In addition, considering that conventional sleeve foaming fastening form cannot be applied to the thermoplastic fiber web structure, a completely novel fastening form is provided for the automobile interior part to match the wrapping of the thermoplastic fiber web structure.
