2012-3-23 · Mr Steef Staal, DMC managing director said, “The new spinning machinery, developed in the past two years, makes the production of nozzles much easier and gives an improved end product, because there is only a single weld seam on the inner side of the nozzle. Manufacturing the complete inside of a nozzle in one go is very special.
Get Price2017-5-18 · In rotary jet spinning technology, a rotating nozzle extrudes a solution of extracellular matrix (ECM) into nanofibers that wrap themselves around heart valve-shaped mandrels. By using a series of mandrels with different sizes, the manufacturing process becomes fully scalable and is able to provide JetValves for all age groups and heart sizes.

The two parallel nozzle orifices enable spinning of single (c,d) or double (e) fibers by co-extrusion of spinning dope through both nozzle orifices.
Get PriceElectrospinning is an established method of producing nano- and micro-fibres from a wide variety of natural and synthetic polymers. A polymer solution is injected through a nozzle or needle which is charged to a high voltage. The applied voltage induces a charge on the surface of the liquid droplet and when this is sufficiently high, the ...

Get Price2020-12-15 · This process is advantageous because the emulsion can be spun by a single spinning nozzle to obtain the nanofiber with a multi-core structure or core-shell structure without using a coaxial nozzle (Fig. 3(C)). During this process, the emulsion droplets can be drawn out in the nanofibers to create a core-shell structure or can remain as droplets ...
Get PriceNMO spinning method. The advantage of the special NMO production method is that there are no chemicals used for dissolving the cellulose. Instead of the chemical viscose spinning solution, organic and non-toxic NMO (N-Methylmorphlin-N-Oxid) is used to dissolve the cellulose which is then pressed through the spinneret.However, the requirements for the spinneret for the NMO …
