Production of recycled EPS fibers by centrifugal spinning
نویسندگان
چکیده
Centrifugal spinning is a new technique for producing of nano and microfibers that has great differential: higher production rate than those presented by traditional methods. Due to interest in using technological applications along with the environmental polymer recycling, this research had purpose fibers centrifugal from expanded poly-styrene recycling evaluation influence operational parameters such as concentration solution speed rotation average diameter distribution diameters formed. The obtained were characterized Scanning Electronic Microscopy (SEM) they their measured ImageJ software. entangled, woven, fused, rough porous surface, bead formation without directional ordering. results show was most influential parameter analyzed characteristics and, general, its increase generates an diameter. With speed, there been often reduction presence beads microparticles due better stretching fibers. In less concentrated solutions, continuous more regular surfaces obtained, however, promoting beads. we noticed very surfaces, well fused woven Through measurement diameters, it possible observe obtaining 407,02 nm 38113,20 nm, smallest value 5% w/w 15000 rpm highest 15% 10000 rpm.

Composite Fibers from Recycled Plastics Using Melt Centrifugal Spinning
New methods are being developed to enable the production of value-added materials from high-volume, low-cost feedstocks arising from domestic recycling streams. In this work, recycled bottle-grade polyethylene terephthalate, polystyrene, and polypropylene were spun into fibers from the melt using a centrifugal spinning technique. Mono-component fibers and 50/50 blends of each polymer and a 33/3...
متن کاملFabrication of κ-Carrageenan Fibers by Wet Spinning: Spinning Parameters
This study demonstrates the fabrication of κ-carrageenan fibers by a wet-spinning method and discusses three important spinning parameters: coagulation bath composition, spinning rate and post-spinning mechanical drawing. The as-spun fiber diameter decreased with KCl and ethanol concentration in the coagulation bath. In general, the ultimate tensile stress and elongation at break both increased...
متن کاملPreparation and Properties of Gelatin Fibers Fabricated by Dry Spinning
Gelatin fibers have been prepared by dry spinning based on the sol-gel transition phenomena of aqueous gelatin solutions. This method is simple and environmentally friendly because only water is used for the spinning, thereby avoiding the use of any toxic organic solvents. A sol-state aqueous solution of gelatin at 50 ̋C was extruded into air through a thin nozzle at room temperature followed b...
