“…Polypropylene is also a polymer of the olefin family with chemical formula (C 3 H 6 )n. Polypropylene fibers are manufactured and commonly employed as nonwoven HEPA-quality air filter units for home and office [ 55 ]. Polypropylene fibers are hydrophobic, water repellent, not easily dissolved, and washable [ 56 ]. The most common method of producing polypropylene fibers is by melt-spinning, where polypropylene granules are melted at temperatures around 210 to 270 °C, extruded and drawn through a spinning die, and quenched at about 30 °C [ 56 ].…”

Polypropylene fibers have a melting temperature of 165 °C; however, polypropylene molecular chains degrade at temperatures above 100 °C, which limits their use in higher temperature applications.…”

“…Polypropylene fibers are useful components in boat mooring ropes because of their ability to float, and their hydrophobicity [ 56 ]. However, polypropylene fibers deteriorate over time through an aging process, i.e., oxidation in air.…”

“…However, polypropylene fibers deteriorate over time through an aging process, i.e., oxidation in air. Polypropylene fibers also deteriorate through exposure to UV light [ 56 ] and become brittle and rapidly lose strength at temperatures below 0 °C and when they age [ 56 ]. Table 8 shows the density, tensile strength, and specific strength for selected olefin synthetic fibers.…”

The purpose of this review is to survey, categorize, and compare the mechanical and thermal characteristics of fibers in order to assist designers with the selection of fibers for inclusion as reinforcing materials in the additive manufacturing process. The vast “family of fibers” is described with a Venn diagram to highlight natural, synthetic, organic, ceramic, and mineral categories. This review explores the history and practical uses of particular fiber types and explains fiber production methods in general terms. The focus is on short-cut fibers including staple fibers, chopped strands, and whiskers added to polymeric matrix resins to influence the bulk properties of the resulting printed materials. This review discusses common measurements for specific strength and tenacity in the textile and construction industries, including denier and tex, and discusses the proposed “yuri” measurement unit. Individual fibers are selected from subcategories and compared in terms of their mechanical and thermal properties, i.e., density, tensile strength, tensile stiffness, flexural rigidity, moisture regain, decomposition temperature, thermal expansion, and thermal conductivity. This review concludes with an example of the successful 3D printing of a large boat at the University of Maine and describes considerations for the selection of specific individual fibers used in the additive manufacturing process.

“…PP fibers have found many applications owing to their balanced physical and chemical properties, such as low density, high crystallinity, high stiffness or hardness, good chemical resistance of polymer [4,5], and a relatively easy spinning which makes it possible to achieve very high extension of macromolecular chains and their maximum alignment [6,7]. The most common process for fiber productions consists of (i) the melt spinning in which fibers are extruded through a die and (ii) fiber drawing [8,9]. Adjustments of extrusion temperature, die size, winding speed and cooling temperature affect structure and properties of the as-spun fibers/filaments [10,11].…”

Effects of Fumed Silica and Draw Ratio on Nanocomposite Polypropylene Fibers

et al. 2017

Abstract:Hydrophylic fumed silica AR974 was tested as a potential nanofiller for the production of composite isotactic polypropylene filaments/fibers (containing 0.25-2 vol % of nanoparticles) via melt compounding and subsequent hot drawing. The objectives of this study were as follows: (i) to investigate the effects of the composition and the processing conditions on the microstructure and the thermal and mechanical properties of the produced fibers; (ii) to separate the effects of silica addition from those produced by fiber drawing; and (iii) to interpret the changes in the matrix molecular mobility (produced by silica and/or drawing). Scanning electron microscopy (SEM) evidenced a good dispersion of nanoparticles at fractions up to 0.5 vol % of the nanofiller. X-ray diffraction (XRD) analyses revealed the increase in crystallinity after drawing of both neat polypropylene (PP) and produced nanocomposite fibers. Consequently, tensile modulus and stress at break of the fibers were enhanced. Drawn fibers containing 0.25-0.5 vol % of nanofiller showed also a remarkable increase in the creep resistance. Loss modulus of drawn fibers showed a pronounced α-relaxation peak at about 65 • C; the higher the draw ratio, the higher the peak intensity. Thermal and mechanical properties of composite fibers were improved due to the combined effects of nanofiller reinforcement and fiber orientation produced during hot drawing. Both fumed silica and draw ratio were significantly effective on tensile modulus and tenacity of nanocomposite fibers up to 0.5 vol % of AR974.
