초록
섬유는 상호 접촉을 동반하면서 발생하는 사망 또는 성폭력 사건 등에서 가해자, 피해자 또는 사건현장의 상호 관련성을 입증하는데 유용하게 활용될 수 있다. 사건현장에서 섬유를 채취하는 가장 일반적인방법은 전사테이프법이며, 다양한 분석을 위해서는 섬유를 분리해야 한다. 섬유를 분리하는 다양한 방법들이 활용되고 있으나 대부분 많은 시간과 노력이 소요되어 보다 간단하고 신속한 채취법이 요구되고 있다. 섬유가 부착된 부위에 핀셋 끝부분의 모세관작용을 이용하여 용제를 섬유 부착부위에 전이시킴으로써 점착제성분의 용해 후, 핀셋으로 섬유를 곧바로 집어 채취하는 것이 가능하여 신속한 채취가 가능하였다. 또한 모세관작용에 의한 미량의 용제 전이로 섬유 채취 시 용제 흡입에 의한 유해성을 크게 감소시킬 수 있었다. 이러한 모세관작용에 의한 용제전이법은 개별섬유채취를 위한 V형 절단채취법과 다량섬유채취를 위한 섬유부착면채취법에 적용하여 섬유의 신속한 채취가 가능하였다
Abstract
Fibers could be usefully employed to prove the interrelationship between perpetrators, victims, or crime scenes in death or sexual violence cases that occur through mutual contact. The most common method of collecting fibers at crime scenes is tape lifting, and for various analyses, fibers must be separated from the tapes. Various methods of separating fibers are being used, but most of them require a lot of time and effort. Thus simpler and faster collecting method is required. By transferring the solvent to a fiber attached site by using the capillary action of tweezers to the area to which the fiber is attached, it is possible to immediately collect the fiber with tweezers after dissolving the adhesive component. In addition, it can significantly reduce the harmfulness caused by solvent inhalation due to a trace amount of solvent transfer by capillary action. This solvent transfer method by capillary action can be applied to the V-shaped cutting method for individual fiber preparation and the fiber attached surface collection one for a large number of fibers to enable fast collection of fibers.
