Three-dimensional net structure with sound attenuation and high elasticity performance

The invention relates to a three-dimensional net structure with sound attenuation and high elasticity performance. The structure is made of a thermoplastic elastomer, the material hardness is in a range of 80-98 A, the density of the three-dimensional net structure is 20-100 kg/m , and the structure is made of two different types of fibers including (1) hollow fibers which have the wire diameter of 0.3-2 mm and account for 40%-95% of all hole counts and (2) solid special-shaped fibers which have the wire diameter of 0.05-0.6 mm and account for 5%-60% of all hole counts. The compressive deformation durability, resilience, adaptability and sound attenuation performance of a support product are improved, so that the three-dimensional net structure has the longer service life and sound attenuation comfort when used as a buffer material. 本发明涉及具有消音、高弹性能的立体网状结构，由热可塑性弹性体制成，材料硬度介于80～98A，该立体网状结构密度为20～100kg/m，由两种不同型态纤维制成，两种不同型态纤维分别为(1)中空纤维：线径在0.3～2mm间，占所有丝孔数分率的40～95%；(2)实心异型纤维,线径在0.05～0.6 mm间，占所有丝孔数分率5～60%。本发明提高支撑产品的压变耐
