Synthetic fiber Manufacturing Optimally Implemented with Siemens Engineering

Synthetic Fiber Automation - Main

Synthetic fibers make up an ever-growing proportion of fiber production worldwide. In contrast to natural fibers, whose associated cultivation regions, e.g. for cotton, are finite and are in direct competition with foodstuffs and plants used for energy production, so far no finite limitations can be seen for synthetic production capacities. As a starting basis, crude oil will continue to be available in sufficient quantities. Consequently, further growth of the production capacity will also be achieved in the near future in order to cover the increasing needs of a quickly growing world population.

For decades, Siemens has proven itself to be a reliable partner for mechanical engineering with its drive and automation solutions, its reliability in the use of extruders, spinning machines, texturizers, and coil winding machines.

Spinning Plants for Synthetic Fibers

Synthetic Fiber Automation - Spinning Plant

BCF spinning plants permit the production of bulked continuous filament in a continuous spinning/drawing/3D curling process for fine and heavy carpet and polyester yarn. The yarn is manufactured as purely white or spun-dyed yarn, single or multi-colored, for 2, 3 or 4 threads per position, at up to 5000 rpm in a vertical production arrangement.

Solution Example

Siemen solutions for spinning plants for synthetic fibers ensure optimum production results with convenient and easy control and highest accuracy.

Fiber Line

Synthetic Fiber Automation - Fiber Line

Fiber lines for staple fiber production are divided into two categories:

  • Discontinuous fiber lines for the production of different 2D crimped fibers for production capacities of up to 250 tons per day of polymers and bi-components recycled from PA6, PA6.6, PET, PP, PTT

  • Continuous fiber lines for the production of PAC fibers in a wet spinning and drawing process for production capacities of up to 100 tons per day


Solution Example

All drives and the process are controlled via PROFINET .The ET 200 distributed I/O reduces the cabling in the plant and additionally supplies all information for the control and visualization to the SIMATIC controller via PROFINET. The WinCC stations permit direct control, monitoring, and logging of the production.

Filament Winder

Synthetic Fiber Automation - Filament Winder

In synthetic fiber spinning plants, winders complete the spinning process. The extremely fine threads from the spinning nozzle are wound onto as many as twelve spools at high speed. Spools are changed without interrupting the spinning process. The take-off speed is up to 8000 m/min depending on the material. Different winding modes are applied: random winding, precision winding, and stepped precision wind.

Solution Example

In this area of application, the intelligent motion control system SIMOTION demonstrates its strengths - the combination of motion control, technology functions, and logic ensures high flexibility, short changeover times, and ease of use.
