Single Yarn Strength Instrument Definition
Fully automatic single yarn strength meter is a high-tech product which integrates the technical characteristics of automatic single yarn strength tester. In addition to the test in the process of the operations done automatically, can obviously increase the work efficiency, to guarantee the machine reliability, improve work stable performance, a number of special effective measures are taken, fully meets the requirement of efficient, accurate, stable and reliable.
The instrument is suitable for all yarns except glass yarn, elastic yarn, aramid yarn, ceramic yarn, carbon fiber, and polyvinyl flat yarn. It can be used to test yarns taken from packages, and by agreement, it can be used to test the remove yarns from fabrics.
The Following Definitions are Used in the Test
Breaking Force: In the tensile test of yarn, the specimen bears the greatest force when it is stretched to fracture.
Elongation at Break: The increment of specimen length from fracture strength, which is expressed as the percentage of sample length.
Breaking Tenacity: The ratio of yarn breaking strength to its linear density.
Package: The yarn suitable for use, transportation, storage, and other forms.
This function should be performed regularly or when the instrument force value is biased. Steps are as follows:
1 The instrument needs 30min for a warm-up after turning on and make the amplifier temperature to reach the normal operating temperature.
2 Select “Force Calibration” to enter the calibration interface.
3 Move the cursor to “0” and press “confirm” to read the base.
4 Hang 1000cN weight, move the cursor to “Full” and press “confirm”, and there is “1000+base” in parentheses.
5 Move the cursor to “Calibration” and press “confirm”, the right side of “calibration” is “1000”. Please repeat the steps as above when there is a difference.
1 Turn on the power, check whether the air pressure is in the range 0.4Mpa-0.8Mpa or not.
2 Turn on the power, and clamp the yarn.
3 Enter the operating interface of the instrument and set the parameters according to the test requirements, such as Test Time, Yarn Num, Bobbins, Elongate, Speed and so on.
4 Click “F2” to start and stop running after the test is finished.
5 If the midway shutdown or power failure, the next time the boot can directly click “F1” to enter “Test” interface, and then click “F2” fixed speed test show the positioning of the yarn. Click “F4” continue to enter the steady-state test, and then click “F2” to continue the last shutdown or power off test.

Q: What is single yarn strength and elongation?
A: Tensile testing of yarns is used to determine the breaking force, elongation, and toughness properties of the yarn. Breaking tenacity, a ratio of the breaking force to yarn linear density is also a common property for evaluating the strength of a yarn material and for comparison and validation purposes. Tensile testing of yarn to determine properties such as breaking strength and elongation includes the use of a tensile testing machine and unique grips to hold the yarn.
Q: What is single yarn strength calculation?
Tmax = 50 – L + f / 9
Where L – 50% span length
f- Fibre fineness
