Problems solved by technology

The light fastness (light fastness) of the non-woven PP fabric with excellent recyclability is somewhat insufficient, and the outer layer material of the TPO series sheet has insufficient scratch resistance on the surface, so it needs to be improved
[0006] In addition, existing automotive headliners with such structures are difficult to recycle due to the use of adhesives for bonding between different materials
Other issues include weight gain caused by laminating different materials, and pungent smell, dust and noise during its production due to the use of materials containing hazardous ingredients and the use of thermosetting resins

Embodiment 1

[0055] This embodiment relates to an automotive headliner having a three-layer structure consisting of a core layer and an outer layer. Both outer layers were made of shell-core bicomponent fiber (CoPET / PET; LM; commercially available from Huvis Corporation) as base fiber and conjugated hollow PET fiber (CH-PET) (commercially available from Huvis Corporation) as reinforcing fiber, and the core The layers were made of sheath-core bicomponent fibers (CoPET / PET; LM; commercially available from Huvis Corporation) as base fibers and conjugated hollow PET (CH-PET) fibers (commercially available from Huvis Corporation) as reinforcing fibers. The outer layer and the core layer are connected to each other by needling, and the bonded nonwoven fabric is produced to have 1200 g / m 2 ±5% uniform weight, and comparatively analyze the change of physical properties with the composition and content of the outer layer and the core layer. From the produced nonwoven fabric, a 6.5±0.3 mm thick aut...

Embodiment 2

[0069] The present embodiment relates to a headliner having a three-layer structure composed of an outer layer and a core layer. Both outer layers were made of sheath-core bicomponent fibers (CoPET / PET; LM; commercially available from Huvis Corporation) as base fibers and conjugated hollow PET fibers (CH-PET) (commercially available from Huvis Corporation) as reinforcing fibers, and The base fiber:reinforcing fiber weight ratio was 70 / 30. The core layer was made of a sheath-core bicomponent fiber (CoPET / PET; LM; commercially available from Huvis Corporation) as a base fiber and a conjugated hollow PET fiber (CH-PET) (commercially available from Huvis Corporation) as a reinforcing fiber. The base fiber:reinforcing fiber weight ratio in the core layer was 60 / 40.

[0070] The outer layer and the core layer are connected to each other by needle punching. In order to analyze the change of physical properties with the weight of the non-woven fabric comparatively, the non-woven fabr...

Embodiment 3

[0077] This embodiment relates to a vehicle headliner having a three-layer structure consisting of a core layer and an outer layer. Both outer layers were made of sheath-core bicomponent fibers (CoPET / PET; LM; commercially available from Huvis Corporation) as base fibers and conjugated hollow PET fibers (CH-PET; commercially available from Huvis Corporation) as reinforcing fibers, and the base The fiber:reinforcing fiber weight ratio was 80 / 20. The core layer was made of a sheath-core bicomponent fiber (CoPET / PET; LM; commercially available from Huvis Corporation) as a base fiber and a conjugated hollow PET fiber (CH-PET; commercially available from Huvis Corporation) as a reinforcing fiber. The base fiber:reinforcing fiber weight ratio in the core layer was 60 / 40.

[0078] The outer layer and the core layer are connected together by needling, and the connected nonwoven fabric is produced with a weight of 1217g / m 2 . From the non-woven fabric, under the same conditions as i...

Abstract

The present invention relates to an automotive headliner, and more particularly to a multilayer automotive headliner, which is manufactured by blending at least one thermoplastic fiber, a sheath-core bicomponent fiber composed of a core component and a sheath component having a melting point and properties different from those of the core component, and at least one functional thermoplastic organic fiber and natural fiber with each other at various blending ratios, and forming the fiber blends into a multilayer structure. The inventive automotive headliner is a thermoplastic organic fiber-reinforced composite material reinforced with functional thermoplastic organic fiber or natural fiber at a suitable ratio and having a two-layer, three-layer or five-layer molded structure, and thus has effects of excellent sound absorption, thermal insulation, impact resistance, moldability and durability. Also, it is a multilayer lightweight automotive headliner which is eco-friendly and recyclable because it contains pure thermoplastic organic fiber and natural fiber without using thermosetting adhesives, polyurethane foams and inorganic reinforcing fibers, such as glass fiber, carbon fiber and boron fiber, as used in the prior automotive headliner.

Description

technical field [0001] The present invention relates to automotive headliners, and more particularly to multilayer automotive headliners produced by mixing at least one thermoplastic fiber in different mixing ratios , a sheath-core bicomponent fiber consisting of a core component and a sheath component having a melting point and properties different from said core component, and at least one functional thermoplastic organic fiber or natural fiber, and preparing said fiber mixture into a multi-layer structure. The automobile headlining of the present invention is superior to the automobile headlining according to the prior art in aspects such as sound absorption and heat insulation; by using a weight of 900g / m 2 ~1500g / m 2 , Expanded material with a thickness of 4mm ~ 8mm has excellent impact absorption and elasticity; it contains layers that are bonded to each other by using different melting points, without using any adhesives that are harmful to the human body; and because...
