Core structure and working mechanism
Core features of the FCT 8th generation MBR spinneret plate
Its features center on three core principles: maintenance convenience, precision design, and production scalability.
Maintenance convenience: split architecture and quick disassembly
This is the most intuitive breakthrough of FCT technology, directly tackling the time and labor intensive maintenance of traditional spinnerets.
Precision design: monolithic spinneret core and ultra high accuracy
While enhancing maintainability, it pursues extreme precision in key components.
Production scalability: multi-hole expansion and outstanding reliability
The design strongly supports large scale industrial production.
Trustech Spinneret Key Design Elements Trustech
These parameters are fundamental to spinneret design and directly determine the membrane's final performance:
|
Parameter |
Description |
Influence on membrane performance |
| Flow channel (R) | The runner for transporting, buffering, and distributing the dope and bore fluids. | Different structures should be optimized according to material properties, viscosity, spinneret orifice size, and hole quantities to achieve optimal spinning performance. |
| Annular gap width (d) | The gap (thickness) of the dope flow channel. | It primarily determines the hollow fiber wall thickness. Narrower gaps yield thinner walls and lower mass-transfer resistance, but may reduce mechanical strength. |
| Bore tube outer diameter (d₁) | The outer diameter of the central tube forming the inner wall of the annular gap. | Together with the outer sleeve inner diameter, it defines the annular gap width. |
| Outer sleeve inner diameter (d₂) | The inner diameter of the spinneret outer sleeve forming the outer wall of the annular gap. | Together with the bore tube outer diameter, it defines the annular gap width and the fiber outer diameter. |
| Central tube inner diameter (d₃) | The diameter of the bore fluid channel. | It primarily determines the fiber inner diameter. The inner diameter affects membrane module packing density and the pressure drop of fluid inside the fiber. |
| Length-to-gap ratio (L/d) | The ratio of the flow channel length (L) to the annular gap width (d). | It affects spinning stability. Designing an appropriate L/d according to material properties and process conditions helps stabilize flow and eliminate entry effects, resulting in more uniform extruded fibers membrane. |
| Concentricity | The coaxial alignment among the dope layer inner diameter at the spinneret outlet and the bore tube inner and outer diameters. | It affects wall-thickness uniformity and bubble point pressure. |
| Extrusion face geometry | The foremost geometry of the spinneret, such as flat or micro-tapered. | It influences draw-down and deformation after extrusion, especially important for the air-gap segment in dry-wet spinning. |

FCT Design
We can offer FCT designs that allow the spinneret core to be removed, replacing conventional designs where each spinneret hole cannot be independently replaced or disassembled. If one hole has a quality issue, the entire spinneret traditionally needs repair or scrapping. Our FCT spinnerets are independently designed so each hole can be individually replaced if needed. The FCT 6th-generation spinneret enables independent on/off control of the dope feed for each spinneret core, and the 8th-generation FCT spinneret cores can be changed online within a few minute down to 50 seconds when problems occur,to ensure continuous production without downtime.
