“…The masterbatch, PLA pellets, and PEG were mixed according to the compositions in Table 3 ; the mixture was melt-extruded using a single-screw extruder with a 24-hole spinneret and a diameter size of 0.32 mm, spinning temperature between 190 and 220 °C, screw speed of 8 rpm, and free fall at draw speed of 500 m/min for spinning the glittering biocomposite fibers. This parameter is developed and modified from the studies in the literature of Pivsa-Art et al ( 33 ) and Prahsarn et al ( 34 ) During spinning, it was observed that to evaluate fiber spinnability, the continuous and steady spinning of fibers without breakage was regarded as good fiber spinnability. The nomenclature and spinnability of the glittering biocomposite fibers are given in Table 3 .…”

Golden glittering biocomposite fibers from poly(lactic acid) (PLA) and nanosilver-coated titanium dioxide (Ag/TiO 2 ) were successfully prepared via a melt spinning process. Various contents of 10% Ag/TiO 2 /PLA masterbatch were diluted with PLA in concentrations of 5, 10, 15, 20, 25, and 30 phr, respectively. The physical, mechanical, thermal, and antibacterial properties of the obtained fibers were investigated. The results indicated that the glittering biocomposite fiber had a light, yellow-gold color and a slightly rough surface. Tenacity and elongation at break of the glittering biocomposite fibers were lower than those of the pristine PLA fiber. The thermal properties of the glittering composite fibers also decreased with increasing masterbatch content. The PLA/PEG-10 biocomposite fiber with good spinnability and mechanical properties was suitably used for preparing the golden glittering composite fabric by the knitting process. Moreover, the golden glittering biocomposite fabrics exhibited antibacterial activity against certain microbes, for example, Staphylococcus aureus , Bacillus subtilis, and Candida albicans . The prepared fabric has significant potential for use in eco-friendly textile products and antibacterial fabrics. Besides, our novel textiles showed not only the photocatalytic property needed to degrade organic dyes such as methylene blue in water but also the ion-sensing property for mercury(II) ions by changing the textile color from yellow to colorless.

“…Modification can be carried out in a polymer matrix of fibers, when they are synthetic or man–made fibers. Prahsarn et al [ 3 ] created a novel luminescent substance, the 3,12-Bis(dibutylamine)-7,8-dicyano-5,6,9,10-tetrahydro (5) helicene (M123), and incorporated into polypropylene fiber during the melt–spinning process. The fibers were characterized by different cross-sections and emission of green light under UV excitation.…”

This article presents the results of research related to the development of cellulose man-made fibers with luminescent properties. The fibers were obtained from regenerated cellulose with the use of the N-Methylmorpholine-N-Oxide (NMMO) method for lyocell (Tencel) fiber formation. The method is named after the cellulose solvent (NMMO) used to obtain the spinning solution. Fibers are formed by the dry–wet spinning method. Due to the characteristic of the lyocell process, the fibers were easily modified to achieve luminescent properties with star-shaped organic compound poly((9-carbazolyl)methylthiirane) (KMT). Fibers were examined on their mechanical parameters with the use of Zwick Z2.5/TN1S tensile testing machine, and the results show the influence of the KMT concentration in the fiber matrix on mechanical parameters of the fibers. The study also attempted to determine the concentration of the modifier in the fibers with the use of UV-VIS Spectrofluorometer JASCO. The luminescent properties of fibers were estimated as well, using Jobin–Yvon spectrofluorometer FLUOROMAX–4, and the results are very promising as the fibers emit blue light in the range of visible light spectrum even for small concentrations of KMT (about 0.1 wt.%).

“…The fluorescent anti-counterfeiting fiber has aroused more and more attention in the recent years [4][5][6][7]. However, the research of fluorescent anti-counterfeiting fiber was mainly focused on single wavelength anti-counterfeiting fiber, which only emits one color under the excitation of a special light [6][7][8][9]. Therefore, it is easy to be forged and cannot satisfy the demands of anti-counterfeiting technologies with the improvement of forgery techniques.…”

The UV short-wavelength/infrared excitable dual-wavelength fluorescent anti-counterfeiting polypropylene (PP) fibers were spun by the traditional melt spinning process. The effects of pH value, temperature, and solvents on the structure and properties of fibers were investigated by means of tensile tester, fluorescence spectrometer and scanning electron microscope (SEM), respectively. The results showed that the fibers could emit red light under the excitation of 254 nm wavelength UV light and emit green light under the excitation of 980 nm wavelength infrared light, which show the double anti-counterfeiting effects. The dual-wavelength fluorescent fibers showed stable mechanical properties in acid and alkali resistance, whereas the fluorescence properties of fibers decreased with the increase of processing time in acid and alkali solutions. With the extension of high temperature treatment time, the mechanical properties of fibers decreased slightly and tended to be stable, while the fluorescence performance of fibers decreased gradually. The influences of different organic solvents on the properties of fluorescent fibers were different, and the fibers showed relatively good solvent resistance.
