Abstract
This study is a follow-up to ‘Research on the Development of Fabrics for Industrial and Firefighting Protective Clothing and Comparison of Flame Retardant Performance,’ focusing on the thermal protection performance of clothing designed to protect the human body from high temperatures and heat in industrial settings and fire scenarios. In this study, additional thermal protection performance tests were conducted to provide a more comprehensive analysis. Aside from the flame-retardant performance evaluation conducted according to ISO 15025 on 12 base fabrics with different yarn compositions, the following thermal performance studies were carried out: radiant heat protection (ISO 9151), convective heat protection (ISO 6942), and combined radiant and convective heat protection (ISO 17492). The heat-transfer index of the intermediate layer, which plays a crucial role in the thermal protection performance of thermal clothing, was also assessed. The results indicated that although most of the 12 base fabrics offered a certain level of thermal protection, some of them melted and failed to provide adequate thermal protection.

요지
본 연구는 고온 및 고열의 산업 및 화재현장으로 부터 인체를 보호하기 위한 방열보호복에 대한 열적방호성능평가를 다룬 ‘산업용 및 소방용 보호복 원단 개발 및 방염성능비교 연구’의 후속연구로써 추가적인 열적방호성능평가를 수행하여 종합적인 분석결론을 도출하였다. 원사조성이 상이한 12종의 원단(Base Fabric)을 대상으로 수행한 ISO 15025에 의한 방염성능 평가 외에 추가적인 열적성능평가로 복사열 방호성능(ISO 9151), 대류열 방호성능(ISO 6942), 복사열 + 대류열 방호성능(ISO 17492)에 선정하고 방열보호복의 열방호성능에 영향을 미치는 중요한 역할을 하는 중간층(Base Fabric)에 대해서 열전달지수(HTI: Heat Transfer Index)평가를 수행하였다. 분석결과 12종의 원단(Base Fabric) 중 대부분은 일정수준의 열적방호성능을 나타냈으나 일부 조성의 Base Fabric은 용융하여 열방호 성능을 가지지 못한 것으로 나타났다.
