... by members of the ENFSI (European Network of Forensic Science Institutes) European Fibres Group (EFG) on three dyed fibers: two red acrylics and one red wool. Raman instruments from six different manufacturers were tested as well as nine different laser wavelengths ranging from blue (λ = 458 nm) to near...

...MC Grieve, B.Sc.; KG Wiggins The current emphasis on DNA technology in forensic science has led many to believe that trace evidence examinations, including fibers, may be of little value. Reasons are given here to show that this is an erroneous assumption. In the face of this situation, fibers...

...C Cwiklik, B.S. Several criteria are proposed for making decisions about comparing sets of debris involving the transfer of non-component particles and fibers—those produced from something other than the item itself—using a model based upon rudimentary set theory. Decisions about the significance...

...SF Swinton, B.S. The discovery of hair and fiber evidence can be of critical importance in the investigation of crimes, particularly violent crimes. A procedure is described for the construction and assembly of a roller device that utilizes readily available components and single-sided adhesive...

...R Palmer, PB.Sc.(Hons), M.Sc. Laboratory coats which had been subjected to contact with a yellow polyester/cotton polo shirt and were subsequently sent to an external laundry service. Surface debris tapings were taken from the items on return, and these were searched for fibers originating from...

...IP Keen, B.App.Sc.; GW White, B.App.Sc.; PM Fredericks, D.Phil. A set of fibers, mainly synthetic, has been examined by Raman microprobe spectroscopy. It was found that high quality spectra, requiring no sample preparation, are easy to obtain and that fibers with different molecular structure have...

..., fibers, trace evidence There is now considerable support for the Bayesian approach to assessing evidence in the context of a legal adversary system (2-5). The examples which are described in the literature tend, of necessity, to be relatively simple and practical complications are minimized so...

...J Wąs, Ph.D.; D Knittel, Ph.D.; E Schollmeyer, Ph.D. (Prof.) The analysis of thermally changed, e.g., melted, decomposed, burned, or incinerated textile fibers by FTIR spectroscopy is described. This method allows us to observe the pathway of fiber thermal degradation and to find the chemical...

...R Palmer, B.S., M.S.; V Chinherende, B.S., M.S. A target fiber study using two garments purchased from two major UK clothing retail chains was carried out using cinema and car seats as potential recipient items. A total of 17 acrylic fibers matching one of the target garments and six cotton fibers...

... analyzed for trace evidence. Three types of corresponding fibers and four possible pathways of transfer were identified. Synthetic fibers similar to those composing the car seat covers were located on the victim's clothing, consistent with direct transfer. Secondary transfer was indicated by dyed brown...

...RD Koons, Ph.D. Energy dispersive X-ray fluorescence (XRF) provides the capability for elemental characterization of individual carpet fibers of a few millimeters in length. XRF is rapid, nondestructive, and provides adequate sensitivity to detect the presence of a variety of elements added...

...SF Stoeffler, M.S.F.C. A flowchart system for identifying common types of synthetic fibers is described. Based on polarized light microscopy, the system allows the rapid identification of the nine generic classes of synthetic fibers most often encountered in casework. 21 03 1995 10 07...

... of the pillowcase revealed fragments of a bloody fingerprint and bloody patterns that seemed to indicate the type of weapon used. A thorough search of the woman's bedroom resulted in the recovery of three small blood stains, a wig fiber and a head hair. Although the body of the victim was not recovered during...

...P Brauner, M.Sc.; A Zamir, M.Sc.; A Gorski, M.Sc.; H Granger-Taylor, M.A.; A Sheffer, M.A.; I Salmon, M.A. Two wall hangings, from the time of the Second World War, were reportedly made from human hair. Laboratory examination of the hangings confirmed this fact. Fibers, holding the wall hangings...

...R Spencer, B.A. An adhesive tape lint removal roller was used to isolate fibers from a homicide victim's clothing that had been exposed to the elements for twenty-nine days. Comparison microscopy, microspectrophotometry, and infrared analysis were used to compare recovered fibers to known fibers...

...K Kretschmer, D.Sc.; W Helbig Six types of colorless commercial poly(ethylene terephthalate) polyester fibers (PET) from different manufacturers were investigated using two-dimensional high-performance liquid chromatography (HPLC). As to their peak structure and area distribution...

...GW White, B.App.Sc. Infrared spectra were obtained from single microfibers using a specifically designed anvil and template to preflatten the fiber perpendicular to the infrared (IR) path. A series of IR spectra of fibers from the Collaborative Testing Service (CTS) reference Collection...

...LL Flinn, M.S. The potential for transfer of fiber evidence during the commission of a crime and the use of such evidence in criminal investigations have been well established. One of the accepted methods for collection of fiber evidence is the use of adhesive lifts, generally adhesive tape...

...RR Bresee, Ph.D.; PA Annis, Ph.D. This paper reports an investigation of the influence of fabric softener on fiber transfer, using a relatively new fiber transfer abrasion tester. Nine medium-weight apparel fabrics were evaluated with and without fabric softener. Fiber transfer from these fabrics...

...MW Tungol, M.F.S.; A Montaser, Ph.D. Infrared (IR) microscopic analysis was performed in tandem with traditional techniques of fiber analysis in case studies in order to determine the feasibility of IR microscopy as a routine technique for fiber analysis. All fibers which were comparable by visual...
