Problems solved by technology

[0008] In addition, car headliners using urethane foam, which is a commonly used material, have good sound absorption, but have the problem of poor weather resistance, resulting in reduced service life, such as discoloration or foam cell breakage after long-term use, and due to the use of adhesive The agent makes it bond with other materials such as fiberglass for strength, making it difficult to recycle
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 to Embodiment 4

[0040] The shell / core bicomponent fiber (CoPET / PET fiber; Huvis Corp.) as the base material and the conjugated hollow PET fiber (CH-PET; Huvis Corp.) / PET) to reinforcing material (CH-PET) in a weight ratio of 70 / 30 (Example 1), 60 / 40 (Example 2), 50 / 50 (Example 3) or 40 / 60 (Example 4) .

[0041] The blended fibers are passed through a cylindrical card machine to form a thin web, which is then joined together by needling, thereby producing a nonwoven fabric. The nonwoven fabric is formed directly in a mold for a car headliner. Alternatively, the nonwoven fabric can be formed into a composite sheet in a continuous type composite sheet manufacturing facility configured to perform preheating, heat bonding, pressing, A series of processes such as cooling, expansion, and cutting, and then molding the manufactured composite sheet in a mold, thereby manufacturing a weight of 1200g / m 2 , A car roof with a thickness of 6mm. The performance of the automotive headliner manufactured a...

Embodiment 5 to Embodiment 8

[0052] Car headliners were manufactured in the same manner as in Examples 1 to 4, except that a shell / core bicomponent fiber (CoPET / PET fiber; Huvis corp.) was used as a base material, and a conjugated hollow PET ( A mixture of CH-PET) fibers and double-crimped PET fibers (DC-PET fibers) was used as a reinforcing material, and the weight ratio of CoPET / PET:CH-PET:DC-PET was 60 / 35 / 5 (Example 5), 55 / 35 / 10 (Example 6), 50 / 40 / 10 (Example 7) or 50 / 20 / 30 (Example 8). Samples were prepared in the same manner as in Example 1 to Example 4, and sag was measured after 24 hours.

Embodiment 9 to Embodiment 12

[0061]Car headliners were produced in the same manner as in Examples 1 to 4, except that a shell / core bicomponent fiber (PP / PET fiber; Huvis Corp.) was used as a base material, and a conjugated hollow fiber ( CH-PET fiber; Huvis Corp.) as reinforcement, and the weight ratio of substrate (PP / PET) to reinforcement (CH-PET) was 70 / 30 (Example 9), 60 / 40 (Example 10) , 50 / 50 (Example 11) or 40 / 60 (Example 12). Samples were prepared in the same manner as in Example 1 to Example 4, and sag was measured after 24 hours.

Abstract

The present invention relates to a recyclable eco-friendly automobile headliner, and more particularly to an automobile headliner comprising an expanded composite sheet formed by integrally expansionmolding a base material, comprising a sheath-core bicomponent fiber composed of a high-melting-point core component and a low-melting-point sheath component, with a reinforcing material composed of afunctional thermoplastic organic fiber. The inventive automobile headliner shows the same thermal resistance and dimensional stability as those of the prior automobile headliner, and at the same time,has improved noise absorption and thermal insulation compared to the prior automobile headliner because it utilizes the functional thermoplastic organic fiber having excellent elasticity and expandability. In the inventive automobile headliner, a covering material is adhered to the substrate using the difference in melting points. Also, the inventive automobile headliner has useful effects in terms of improvement of the working environment and maintaining of human health due to the use of only eco-friendly recyclable materials in place of the prior thermosetting material and inorganic fiber.

Description

technical field [0001] The present invention relates to a recyclable and environmentally friendly automotive headliner comprising an intumescent composite sheet formed by an integral intumescent molding base material and a reinforcement material composed of functional thermoplastic organic fibers, the The substrate comprises a sheath-core bicomponent fiber consisting of a high-melt core component and a low-melt sheath component. The car headliner of the present invention exhibits the same heat resistance, dimensional stability, and impact resistance as the prior car headliner, and in addition, the car headliner of the present invention utilizes Functional thermoplastic organic fiber, which has improved sound absorption and heat insulation performance compared to the previous car headliner, excellent impact absorption and elastic properties due to the use of expanded base material, and has a weight of 800g / m due to the use of 2 ~1600g / m 2 , Thickness is the expansion matrix o...
