The present invention relates to a nonwoven laminate, a shaped article, use thereof, a product and a production process. The non-woven laminate comprises a non-woven layer (A) comprising multi-component staple fibers, a non-woven layer (B) optionally comprising multi-component or single-component staple fibers, a needle-punched non-woven layer (C) comprising single-component staple fibers (c1) and multi-component staple fibers (c2), a non-woven layer (D) optionally comprising multi-component or single-component staple fibers, and a needle-punched non-woven layer (C) comprising single-component staple fibers (c1) and multi-component staple fibers (c2). And optionally a non-woven layer (E) comprising multicomponent staple fibers, the layers being arranged in this order (A) to (E), the layers being bonded to each other by melting rather than needling, the multicomponent fibers comprising a polyester component and a copolyester component, the monocomponent fibers in layer (C) being polyester fibers, the monocomponent fibers in layers (B) and (D) being copolyester fibers, and the monocomponent fibers in layers (B) and (D) being polyester fibers. The copolyester content in the layers (B) and (D) is higher than the copolyester content in the layers (A) and (E), and the fibers of the nonwoven laminate are all polyester and/or copolyester fibers.

    本发明涉及一种非织造层压件、成形制品、其用途、产品和生产工艺。非织造层压件包括:包括多组分短纤维的非织造层(A),任选地包括多组分或单组分短纤维的非织造层(B),包括单组分短纤维(c1)和多组分短纤维(c2)的针刺非织造层(C),任选的包括多组分或单组分短纤维的非织造层(D),及任选地包括多组分短纤维的非织造层(E),各层以(A)至(E)的顺序布置,各层通过熔化而非针刺彼此粘合,所述多组分纤维包含聚酯组分和共聚酯组分,层(C)中单组分纤维是聚酯纤维,层(B)和(D)中单组分纤维是共聚酯纤维,层(B)和(D)中共聚酯含量高于层(A)和层(E)中共聚酯含量,非织造层压件的纤维均是聚酯和/或共聚酯纤维。
