Nanofiber lines to create fiber webs in a solution spinning process

DIENES offers nano fiber spinning installations with centrifuge technology which represent a leap forward in many aspects. By the use of high and constant throughput the installation can produce fibers with diameters as low as 80 nm in a simple and compact machine configuration at highest productivity. Centrifugal spinning line with only three heads provide a throughput which is 1.000 times higher than conventional electro spinning installations with 25 rows of 1.250 spin jets. Various polymers can be processed for which a solvent is available.

The technology is used for laboratory units as well as in high-capacity production lines while for all systems the same technological advantages are present.

• compact design, high and constant throughput due to centrifugal spinning and a spin pump
• fiber diameters down to 80-500 nm
• use of proven components
• accurate control of web weight by electrostatic forces and controlled air flow
• stable operation due to constant polymer-solvent ratio
• top-down spinning principle, transport with low substrate tension possible, perfect arrangement for fragile substrates
• easy coating of heavy webs due to separate processes for fiber creation (centrifuge) and web formation (electrical filed)
• variable electrostatic field, variable positioning of centrifuge, variable air flow and variable working width
• design allows to re-feed the substrate
• automatic cleaning run at shut down
• easy access for service
