초록

본 연구에서는 칼과 가위 및 화학약품에 의한 물리·화학적 섬유 손상을 분석하여 손상의 원인 파악을 위한 기술 데이터 자료로써 활용하고자 하였다. 칼 4종류 및 가위 5종류와 4종류의 화학약품(황산, 염산, 수산화나트륨, 수산화칼륨)을 이용하여 면(Cotton), 울(Wool), 폴리에스터(Polyester), 레이온(Rayon), T/C(Polyester 50%, Cotton 50%), T/W(Polyester 50%, Wool 50%)에 물리·화학적 손상을 생성하여 공구와 화학약품에 따른 손상을 분석하였다. 칼과 가위에 의한 관통 손상은 칼의 날 부분이 관통한 경우 공통으로 "V" 유형의 손상이 나타났으며, 칼의 등 부분이 관통한 칼의 경우 "T", "ㅁ", 갈고리, "ㄷ" 유형의 손상이 나타났다. 또한, 가위의 경우 모두 "Y" 유형의 손상이 공통으로 나타났다. 화학약품에 의한 섬유 손상은 유류 흔적, 부식, 분해, 수축, 변색 등 다양한 손상이 나타났으며, 화학약품과 섬유의 종류에 따라 나타나는 손상에 차이를 보였다. 섬유의 물리적 손상은 공구의 형태적 특성에 따라 나타나는 특징에 차이를 보였으며, 화학적 손상은 화학약품과 섬유의 종류에 따른 특징 차이를 보임을 확인하였다.

In this study, the physical and chemical fiber damage caused by knives, scissors, and chemicals was analyzed and used as technical data to determine the cause of the damage. Using 4 types of knives, 5 types of scissors and 4 types of chemicals(Sulfuric Acid, Hydrochloric Acid, Sodium Hydroxide, Potassium Hydroxide) physical and chemical to Cotton, Wool, Polyester, Rayon, T/C (Polyester 50%, Cotton 50%), T/W (Polyester 50%, Wool 50%) Damages were created and analyzed for damage caused by tools and chemicals. For penetrating damage caused by knives and scissors, 'V' type damage was generally seen when the blade part was penetrated, 'T', 'ㅁ', ''C' type damage was found, and in the case of scissors, 'Y' ' This type of damage was common. Fiber damage caused by chemicals showed various damage such as remanent trace, corrosion, degraded, contracting, and color changes. Physical damage of fibers showed differences in characteristics according to the shape characteristics of tools, and chemical damage showed differences in characteristics according to chemicals and types of fibers.
