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.
