This study aims to analyze the changes in the mechanical properties of interlock fabrics knitted with three types of fibers (i.e., cotton, wool, and polyester) by bonding fusible interlinings with varying deniers (i.e., 10D, 20D, and 30D) for a 3D virtual try-on system. We experimented with four properties and thicknesses of twelve specimens of interlining bonded knitted fabrics including face fabrics and interlinings. The results showed that the tensile property changed values (i.e., LT increased, and WT and RT decreased) according to the denier of interlinings; however, the change was slight. On the other hand, the bending property increased significantly as the denier of the interlining increased on both the wale and the course. Among shearing properties, the value of G increased as the denier of the interlining increased on both the wale and the weft; however, 2HG decreased. Additionally, changes in the compression property varied according to the fibers and the denier of the interlinings. The thickness of the knitted fabrics increased or decreased slightly by bonding the interlining. based on these results, we conclude that the 3D virtual system users need to reflect these numerical changes of interlock fabrics by bonding interlinings when they perform fitting tasks on the screen to accurately express the to accurately express the manufacturing conditions of the real garment.

방화댐퍼는 방화구획을 관통하는 덕트에 설치되어 화염의 전파 및 연소확대를 방지하도록 하는 방화설비로서 ‘건축물의 피난·방화구조 등의 기준에 관한 규칙’에서 구조 및 시험 기준에 대해서 규정하고 있으나, 정해진 성능기준이 없어 관련 제도의 개선이 필요하다. 본 연구에서는 방화댐퍼의 ‘KS F 2822(방화댐퍼의 방연시험방법)’에 대해서 소개하고, 시험 항목 중 ‘연동폐쇄장치 작동시험’ 사례를 통해 관련 제도 개선을 위한 적용 타당성을 검토하였다. 검토 결과, 구축된 시험설비의 환경 및 운영 여건에 기인하여 만족할 만한 성과를 얻지는 못하였으며, 시험설비의 충분한 성능 확보를 위해 보완이 필요한 것으로 파악되었다. 방화댐퍼 관련 제도의 개선을 위해서는 보완 후 검토 결과에 따라 대안적인 성능평가 방법의 검토가 필요한 것으로 판단되었다.
