The DIENES wet spinning lines in standard or air-gap execution enable highest performance in the production process. The wet spinning lines consist of various main steps: coagulation - washing – drawing – drying – fixation – winding. 

 We offer:

• Lab lines with independently driven modules

• Pilot plants: modules are connected in the MultiMode® principle

• Production lines

Filament Fibers made from: Polyester (PET),  Polypropylen (PP),  Polyamide (PA6.6, PA6),  Polyacryl (PAN), Textile and Technical Viscose,  New Cellulose NMMO,  SiO2, Al2O3,  Amorphous Materials,  Composite Materials

Equipment for the production and treatment of: Multifilaments low speed spinning (e.g. precursor), Monofilaments (e.g. medical and reinforcement), Nanofibers (webs)

In a MultiMode® plant, each process step is represented by a module which can be individually adapted to customer-specific requirements and has its own decentralized control. Thus, DIENES production lines consist of several intelligent modular units which can be easily exchanged and rearranged at any time with a reduced programming effort. Moreover, all production parameters can be permanently visualized and recorded, enabling a complete traceability of the process. The general set-up and the complexity of the machine depend on the process and the customer's target.

 Wet spinning Lab-Line

Our Wet spinning Lab-Line is a solution spinning laboratory line especially designed for research institutes and is suitable for instance for PAN, PEG, PVA . An Aramid process was already realized in a special design of the lab line.

This affordably priced compact line finds its principal application in the development and research of small amounts of polymer. The modular design and the local control allow to take specific customer requirements into account. You can easily add or exchange modules at any time to achieve fast research results. Furthermore, it is possible to integrate the modules to other manufacturer lines.

The standard DIENES LLC line consists of the following modules:

• Spinning unit with dope supply & coagulation bath

• Washing & drawing unit (with baths or as a duo) and drying section

• Quintet

• Dancer arm cross winder

The LLC is being further developed and is available as MultiMode® LAB too.

The Spinning Unit includes two dope vessels for a more comfortable operation: one vessel can be used for spinning while the other one is in stand-by being stirred and degassed.

The spinning pump will be defined according to the requested viscosity.

The lines has been optimized for Lyocell or similar highly viscous dopes: heating along the spinning pipe, higher grade stainless steel in the spinning line and coagulation bath and higher temperature heating jackets for the dope vessel(s).

DIENES offers mono- and bicomponent compact melt spinning plants according to the MultiMode® principle. The production speed of these lines is up to 6.000 m/min.

The lay out of the extruder with dosing, spinning unit, quench, drawing sections and high-speed winder is adapted to the specific needs of the developers in order to lead to the achieved results.

• Individual yarn path adjustment

• Actively cooled godet

• Speed up to 6.000 m/min

Stabilization is an important process step in the creation of high-quality carbon fibers. For this process DIENES offers furnace systems with high temperature accuracy. The optimized system for yarn transportation with DIENES own godets implements a tension-controlled stabilization.

Subsequently to the stabilization the carbonization of the material follows, which is usually performed in a two-stage process in an inert atmosphere and at temperatures of up to 2.800 °C. DIENES offers thread guiding equipment and together with its partners carbonization ovens.

DIENES also offers modules for the activation process of the carbon fiber which includes treatments such as electrolytic surface treatment and sizing application.

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

MultiMode® - Research 4.0

The development of new innovative filaments demands an efficient systematic and, in part, self-optimising experimental working system, which must be intelligent in gathering data from the process and flexible in enabling the rearrangement of the process.

Our implementation of the Research 4.0 approach is called MultiMode® and ensures high flexibility, modularity and versatile applicability. Each module can be individually adapted to customer-specific requirements and has its own decentralised control, which is the key for its integration into any plant at any time with a reduced programming effort.

In connection with the DIENES visualization unit all process-relevant data is graphically available for the user. Changes in the process can be made effectively by entering data via touchscreen. Through the combination of several DIENES MultiMode® modules and the integration of a MultiMode® Master (MMM), all local controls are displayed in a central control panel.

For the analysis of complex relationships to carry out process analysis the MMM is getting extended by a DIENES MultiMode® Explorer (MME). In the MME developed by Dienes, all process data are permanently visualised and recorded with a high degree of transparency for further evaluation. From system expansions to process development the MultiMode offers a customized process control system for your application.

Control set-up available with:

• Local and central visualization per unit

• Central visualization for line

• Process evaluation in real time

• Data logging for all parameters

• Access control via user administration incl. password
