Fibers Made by Centrifugal Spinning Technology

Popis výsledku v původním jazyce

Centrifugal spinning, Forcespinning&not;TM or rotary jet spinning, all these names represent relatively new and simple technology that allows production of fibers by using only centrifugal forces. These forces are caused by high-speed rotation of the spinneret unit and are necessary for drawing polymeric jet and fiber formation. Two main ways of centrifugal spinning process depend on type of the spinneret unit. These are needle and needle-less technology. Besides that, it is possible to combine centrifugal forces with electric field to produce fibers by electro-centrifugal method. Fibers could be forming from solutions or melts as well. Centrifugal spinning can offer at special conditions several advantages in comparison to electrospinning such as spinnability of liquid form of materials (polymeric solutions or melts, ceramic, metal), larger range of spinnable materials (no requirements on electrical conductivity of material) and higher production rate. Fibers are arranged in one direction and gathered on collector. This homogenous fibrous layer could be used in many different applications, I.e. in biomedical area, tissue scaffolds, drug delivery systems, filtration, energy industry etc. Materials polycaprolactone (PCL), polyvinyl butyral (PVB), polyamide 6 (PA 6), polyvinyl alcohol (PVA), copolymer of polycaprolactone and polylactid acid (PLC), collagen and other have previously been successfully spun. Centrifugal spun fibers generally have wide distribution of their diameters. Big variability in spinning devices, used materials and process conditions lead to production of modified fibers, such as porous fibers, bicomponent fibers and even hybrid and inorganic fibers.
