Application of Digital Yarn Tension Meter in Textile Process Quality Control

Customer Background

The customer is a medium-sized textile manufacturer specializing in wool, chemical fiber, and blended yarn production. The company operates multiple spinning and weaving production lines and supplies yarn products to garment factories and industrial fabric producers.

In recent years, with increasing demand for high-quality and stable yarn products, the customer has placed greater emphasis on process tension control, especially during spinning, winding, and weaving stages. Even slight tension fluctuations were found to directly affect yarn uniformity, breakage rate, and final fabric performance.

Production Challenges Before Equipment Upgrade

Before introducing the digital yarn tension meter, the customer relied mainly on indirect or experience-based tension control methods, which led to several practical issues:

(1) Inconsistent yarn tension across production batches

Operators adjusted machine settings based on experience, resulting in variation between different shifts and production lines.

(2) High yarn breakage rate in weaving process

Unstable tension control caused frequent yarn breakage, especially during high-speed weaving operations.

(3) Lack of real-time quantitative data

Previous inspection methods could not provide accurate static and dynamic tension values, making process optimization difficult.

(4) Difficulty in quality traceability

Without digital records, it was difficult to trace tension-related defects back to specific production stages.

Solution: Digital Yarn Tension Meter Implementation

To improve process stability, the customer introduced our digital yarn tension meter for on-site and laboratory tension monitoring.

The instrument is used to measure both static and dynamic tension of yarn during production, helping operators quickly identify abnormal tension conditions and adjust machine parameters in real time.

Its portable structure allows direct measurement on spinning frames, winding machines, and weaving equipment without interrupting production.

Key Technical Basis of the Equipment Used

The equipment applied in this case includes the following core specifications:

Measuring Range: 0–200 cN

Accuracy: ±1% FS or ±1 digit

Measurement Principle: Strain gauge bridge system

Signal Processing: 12-bit A/D conversion digital processing

Sampling Rate: ~5 kHz

Display: 4-digit LCD display

Line Speed Capacity: up to 3000 m/min (ceramic rod mode)

Damping: 10-level adjustable electronic damping

Portable aluminum alloy structure with battery operation (approx. 50 hours continuous use)

These features allow stable and fast measurement under actual production conditions.

Application Results

After the equipment was deployed in the production line, the following improvements were observed:

(1) Improved yarn tension consistency

Real-time measurement enabled operators to standardize tension settings across different machines and shifts.

(2) Reduced yarn breakage rate

Better control of dynamic tension during winding and weaving significantly reduced production interruptions.

(3) Improved process visibility

Digital tension data allowed engineers to analyze and optimize spinning and weaving parameters more effectively.

(4) Enhanced quality control capability

The laboratory and production departments could now use unified tension data for quality verification and process comparison.

Customer Feedback

The production manager commented:

“Before using the digital tension meter, we mainly relied on experience, which made it difficult to maintain consistent yarn quality. After introducing this instrument, we can clearly see tension changes during production. It has helped us reduce breakage and improve overall stability of our weaving process.”
