In an examination of sexual crime cases, the possibility that constituent fibers of the top sheet of a sanitary napkin or a panty liner, which the victim may have been using, might stick to the suspect's hands and fingers were examined.   Nineteen brands of sanitary products (15 sanitary napkin brands and 4 panty liner brands) were classified, by their material of the top sheet, in 12 brands of non-woven fabrics and 7 brands of porous films. The 12 brands of non-woven fabrics products were classified by their bonding process in 2 types, i.e. thermal bonding (through-air oven bonding) and mechanical bonding. Meanwhile out of 19 brands of products, 9 products have non-woven fabrics on both sides of the top sheet to prevent leakage and all of their bonding processes are thermal bonding (point-bond hot calendaring).   Next, materials stuck to two subjects' fingers were collected on a transparent adhesive tape and examined whether constituent fibers came off and stuck to their fingers when two subjects rubbed the surface of a sample with their fingers. It was found that constituent fibers of non-woven fabrics stuck to the transparent adhesive tape.   As a result, it was found that constituent fibers of non-fabrics came off by rubbing and stuck to fingers and hands, though those of porous films did not stick to them. Consequently, it is suggested that examination of constituent fibers of sanitary products is noteworthy for sexual crime cases.

It is impossible to spend even a day without paper in recent cultural life. Papers are liable to be concerned in many kind of crimes, so that. For example, forgery of bills, duplicate of document, incendiarism and murder are as such. Nowadays demands that are expert discrimination of paper are on the increase. However, complete paper is hardly found in most of these criminal cases. Minute, degenerate and/or stained papers are apt to become evidential matter. Therefore, it is difficult to inspect these papers according as JIS or to inspect them in view of manufacturing technique. So characteristic method is necessary for forensic science.This report is a presentation with regard to some typical discrimination as follows which we have ever done and obtained good result on the field of forensic science.(1) Two examples for inspection of minute or degenerate paper fragment.(2) Two examples for analysis of coatings and filler in woodfree paper and mechanical paper.(3) Two examples for inspection of new domestic articles.
