  • 가시광촉매의 특성 및 가시광촉매가 코팅처리된 자동차내장재 nylon/polyester 복합섬유에 대한 VOCs의 저감에 대해 알아보았다. 가시광촉매 Weltouch의 결정구조는 아나타제상과 루타일상이 복합된 것으로 약 420nm이상의 파장을 갖는 빛에너지에서도 활성을 나타냈다. 또한 가시광촉매가 처리된 자동차내장재 nylon/polyester 복합 섬유에서 발생하는 VOCs 및 포름알데히드는 현저한 저감효과를 나타냈으며, 섬유를 25회 세탁을 행하여도 가시광촉매의 탈락없이 표면에 견고하게 부착되어 가스분해성능을 유지하는 것으로 나타나서 세탁내구성이 우수한 것을 확인하였다.

  • Tire codes are made of materials such as hemp, cotton, rayon, nylon, steel, polyester, glass, and aramid are fiber reinforcement materials that go inside rubber to increase durability, driveability, and stability of vehicle tires. The reinforcement of the tire cord may construct a composite material using tires such as automobiles, trucks, aircraft, bicycles, and fibrous materials such as electric belts and hoses as reinforcement materials. Therefore, it is essential to ensure that the adhesive force between the rubber and the reinforced fiber exhibits the desired physical properties in the rubber composite material made of a rubber matrix with reinforced fibers. This study is a study on the heat treatment conditions for improving the adhesion strength of the tire cord and the reinforced fiber for tires. The core technology of the drying process is a uniform drying technology, which has a great influence on the quality of the reinforcement. Therefore, the uniform airflow distribution is determined by the geometry and operating conditions of the dryer. Therefore, this study carried out a numerical analysis of the shape of a drying nozzle for improving the performance of hot air drying in a dryer used for drying the coated reinforced fibers. In addition, the flow characteristics were examined through numerical analysis of the study on the change in the shape of the chamber affecting drying.
