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.
