Yarn Tension Test Method and Yarn Tension Meter

 Yarn tension is used to measure the tension of moving or static yarn, thin steel wire, and plastic wire, providing a reliable basis for improving material quality and product performance.

Yarn tension

Generally speaking, “yarn tension” can be understood as the degree of tension of the yarn after being subjected to external force.
In the spinning process, there are tensions in roving yarns and fine yarns. To elaborate further, for example, during the twisting and winding process: The tension of the yarn from the front roller to the yarn guide hook is called spinning tension; The tension of the yarn from the yarn guide hook to the traveler is called balloon tension; The yarn tension from the traveler to the bobbin is called winding tension, etc.
The weaving process also involves yarn tension, such as warp tension, weft tension, yarn winding tension, etc.
In textile engineering, yarn tension results from work. The objects that exert force and receive force vary depending on different conditions and situations.
Yarn tension is a process parameter involved in each weaving process.
Tension is not only related to yarn breakage, but also to the efficiency of the equipment. It is also related to weaving shrinkage and fabric quality.
Tension is not only related to the properties of fibers and yarns, but also to the configuration of other process parameters in the production process of each process.
Theory and production practice prove that end breakage is weakly related to the strength of the yarn itself, but closely related to the yarn tension. Therefore, yarn tension is of great significance to production, process configuration and product development.

Yarn tension meter

This digital yarn tension tester is designed to determine the tension of moving or static yarn, fine wire, plastic thread.

Yarn Tension Meters are utilized all over the world in a wide range of standard and specialized applications. Man-made fiber industries, cotton textile industries, knitting industries, optical fiber industries, wire industries, and so on are examples.
Three long and closely spaced slender shafts with precision guide rollers, as well as the end of the middle slender shaft, combine with the most recent microprocessor technology to make this instrument an excellent choice for tension measuring applications. If necessary, the operator can recalibrate the instrument.
Many international and retailer requirements are met by the Yarn Tension Meter.

​Follows are features of tension meter for yarn：

• Aluminum profile with Aluminum outer casing.
• Three long and closely-spaced slender shafts with precision guide rollers, and the end of the middle slender shaft combine with the latest microprocessor technology.
• Employ a strain-gauge system for accurately perceive and record the tension change.
• Adjustable damping (10 steps) for easier readings when tension fluctuates,
• The large LCD display (4-digit) shows dynamic tension values calculated during the update, and can reach to accuracy of 0.1cN.
• The yarn tension meter automatically power off after about 3 minutes of non-operation.
