摘要

PROBLEM TO BE SOLVED: To provide a needle-punched nonwoven fabric using a web for car interior excellent in lightness.;SOLUTION: The needle-punched nonwoven fabric for car interior is constituted by three-dimensionally entangling and integrating a web by needle punch treatment, the web obtained by fiber-blending and carding the main fibers each other which are a thermoplastic polyester hollow crimped short fiber having a fiber cross section shape of a hollow cross section having a hollowness of 5-40%, and a thermoplastic polyester solid crimped short fiber, where the content of the hollow crimped short fiber is 10-90 mass% to 100 mass% of a total amount of the main fibers, the content of the solid crimped short fiber is 90-10 mass%, the crimping of the main fibers is two-dimensional mechanical crimping, the crimp rate of the mechanical crimping is 5-35 mountains/inch, the crimping degree is 5-40%, the residual crimping degree is 3-35%, and the basis weight of the nonwoven fabric is 180-350 g/m².;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
