Fabrication 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...
متن کاملComposite 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 کاملWet-spinning assembly of continuous, neat, and macroscopic graphene fibers
Graphene is now the most attractive carbon-based material. Integration of 2D graphene sheets into macroscopic architectures such as fibers illuminates the direction to translate the excellent properties of individual graphene into advanced hierarchical ensembles for promising applications in new graphene-based nanodevices. However, the lack of effective, low-cost and convenient assembly strateg...
متن کامل1{D Isothermal Spinning Models for Liquid Crystalline Polymer Fibers
A slender 1{D model for laments of liquid crystalline polymers (LCPs) is applied to simulate isothermal ber spinning of materials with internal orientation. The model and predictions focus on the hydrodynamic{orientation interactions in spinning ows, isolated from other signi cant spinline e ects of temperature, crystallization and phase changes. An important practical feature of the model is t...
