New FiberGuard BCF yarn tension sensor

Monitor, adjust, perfect

FiberGuard BCF is the name of the new system for real-time monitoring of yarn tension in all Neumag BCF production processes. Barmag, the innovation and technology leader for filament spinning systems, presented this innovation of its Neumag product line at ITMA Asia + CITME in Singapore last November. The new BCF yarn tension sensor is compatible with all current Neumag BCF machines and can be easily retrofitted to existing Neumag BCF S8 machines.

In FiberGuard BCF, sensors and software ensure that process stability and product quality are sustainably improved. The intelligent system continuously measures the yarn tension between twisting and winding in real time. If there are deviations in the yarn tension, FiberGuard BCF automatically intervenes and adjusts the process independently. The result is less waste, higher efficiency, and greater sustainability.

Operators can use the HMI to call up live data, define individual reporting thresholds, and activate automatic adjustments. In addition, the system enables the creation of customer-specific reference curves for yarn tension during the doffing process.

The solution has been well received by customers, says Jan Pauer, Head of Service Products in Neumünster and responsible for the new system: “Our discussions with interested BCF producers at ITMA Asia have shown that we have listened to our customers. FiberGuard is the next step in all Neumag BCF processes. The combination of hardware and intelligent software opens the door to a new production possibility characterized by reliable thread tension measurement and automated process adjustment.”

Barmag presents the next generation of POY production – energy-efficient and partial-automated

With POY 2.0, Barmag is introducing a completely redesigned spinning concept that takes the production of partially oriented yarn (POY) to a new level in terms of technology and economy. The solution, which was presented to a selected audience of experts for the first time at ITMA Asia + CITME 2025, was met with great enthusiasm: several yarn producers worldwide immediately expressed their interest in a pilot plant.

High-performance yarns for tomorrow's mobility

At this year's Techtextil in Frankfurt (April 21–24), Barmag will be presenting comprehensive solutions for the production of industrial filament yarns at the VDMA joint stand (Hall 12, C56). The focus will be on applications that ensure greater safety, durability, and efficiency in automotive engineering.

Development of bio-based polyethylene fibers for textile applications – BB Engineering partici-pates in the bioPEtex research project

In the German research project bioPEtex, BB Engineering (BBE) is working with other partners to develop textiles made from 100% bio-based polyethylene (PE). The aim is to make use of this poly-mer, which has hardly been used in the chemical fiber industry to date. BBE is contributing its spinning and texturizing expertise and developing the texturing process on an industrial scale. The first promising results are already available – opening up new opportu-nities for sustainable and economically attractive applications in the textile industry.

Rieter advances strategic repositioning amid market volatility

Rieter successfully completed the acquisition of Barmag on February 2, 2026, and reached an important milestone in the company’s repositioning. Barmag will be integrated into the Rieter Group as the “Man-Made Fiber” Division. With this strategically transformative acquisition, Rieter is expanding its core business beyond the short-staple fiber business in a targeted way. This positions Rieter as the global market leader along the entire value chain for natural and man-made fibers. In addition, as a complete systems supplier, Rieter is further strengthening its technological leadership in the areas of automation and digitization.

Measure and control the fiber – optimize yarn quality

Producing consistent yarn quality is an everyday challenge – and a very difficult one. Detailed knowledge and understanding of the fiber raw material is absolutely critical to achieving the best possible quality in the yarn. To help spinners, Uster experts have put together guidelines for avoiding yarn irregularity claims, in a special edition of the Uster News Bulletin.
