Forensic Application of Chemometric Analysis to Visible Absorption Spectra Collected from Dyed Textile Fibers
… profiles collected from highly similarly colored textile fibers via microspectrophotometry (MSP). Several chemometric techniques were applied to spectral data and utilized to help discriminate fibers beyond the point where traditional methods of microscopical examination may fail. Because a dye's …

Development and analysis of a maintenance shop simulator-decision making game
… game involving a maintenance facility in a textile fibers plant. The first part of this paper is a discussion and analysis of decision-making games in general. The second part contains the description of the objectives and the model of the game. An important feature of the game is that the …

A study of the crease-resistance of viscose rayon
… is a very greatly desirable property in textile fibers. Of the natural fibers, wool exhibits this property to the greatest degree, followed by silk, cotton, and flax, which has a very low crease-resistance. The artificial cellulose fibers fall considerably below wool and silk in this …

Fire safety and interior textiles
… for fire safe interiors is an important one. The textile end-products they specify play an important part in the start and/or spread of interior fires. Furthermore, the rate of developments in textile testing and products makes it difficult for designers to keep abreast of the latest information. …

Forensic Analysis of Trace Evidence Fibers and Drugs of Abuse In Biological Matrices Using Chromatographic and Mass Spectrometric Methods
<p>Textile fibers found at crime scenes as trace evidence often provide leads or confirmations in criminal investigations. The development of analytical techniques for forensic discrimination of fibers by micro-extractions of dyes followed by liquid chromatography (LC) or capillary electrophoresis …

Forensic Discrimination, Age Estimation, and Spectral Optimization For Trace Detection of Blood On Textile Substrates Using Infrared Spectroscopy and Chemometrics
… to visualize blood on forensically relevant textiles was evaluated using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). Reflectance spectra of bloodstains contain distinctive amide bands due to the proteins in blood. Amide I, II, and III bands (1650, 1540, and 1200-1350 …

Synthesis and Characterization of Cycloaliphatic and Aromatic Polyester/Poly(dimethylsiloxane) Segmented Copolymers
… applications such as food containers, films and textile fibers. The physical and mechanical properties of these materials are well documented and are a function of chemical structure and morphology (e.g. semi-crystalline, amorphous, etc.). Polyesters, as are many organic polymers, are quite …

Hyphenated fourier transform infrared spectrometry: techniques for separations and analysis
… towards the extraction of finishes from textile fibers. SFE has previously been applied to less complex finish systems. The proposed method making use of intermediate trapping is viable for more complex systems that show limited solubility in a supercritical fluid. Quantification of the …

Chemometrics applied to the discrimination of synthetic fibers by microspectrophotometry
… and reproducible method to compare colored fibers for forensic purposes. The use of chemometric techniques applied to spectroscopic data can provide valuable discriminatory information especially when looking at a complex dataset. Differentiating a group of samples by employing chemometric …

The conserved C-terminal domain of spider tubuliform spidroin 1 contributes to extensibility in synthetic fibers
… mechanical analysis of synthetic egg case silk fibers spun from the Latrodectus hesperus tubuliform silk proteins, TuSp1 and ECP-2. We provide evidence that recombinant ECP-2 proteins can be spun into fibers that display mechanical properties similar to other synthetic spider silks. We also …

The Synthetic spider silk fibers spun from Pyriform Spidroin 2, a glue silk protein discovered in orb-weaving spider attachment discs
<p>Spider attachrnentdisc silk fibers are spun into a viscous liquid that rapidly solidifies, gluing dragline silk fibers to substrates for locomotion or web construction. Here we report the identification and artificial spinning of a novel attachment disc glue silk fibroin, Pyriform Spidroin 2 …
