Single yarn strength usage instructions

1. Product Overview

Single yarn strength refers to the maximum force that a single yarn can withstand when it is stretched and broken, and is one of the important indicators for measuring yarn quality. This product is suitable for testing and evaluating yarn strength in the textile industry.


2. Scope of application

1. Strength test of various types of yarns such as cotton yarn, wool yarn, and chemical fiber yarn

2. Quality control of textile production enterprises

3. Acceptance standards for yarn procurement

4. Material performance research of scientific research institutions


3. Technical parameters

1. Test range: 0-5000cN

2. Accuracy: ±1%

3. Clamping distance: 100mm, 250mm, 500mm (adjustable)

4. Stretching speed: 50-500mm/min (adjustable)

5. Test environment: temperature 20±2℃, relative humidity 65±3%


4. Operation steps


4.1 Preparation

1. Place the instrument on a stable workbench

2. Connect the power supply and preheat for 15 minutes

3. Set the appropriate clamping distance and stretching speed according to the yarn type

4. Prepare the yarn sample to be tested to ensure that it is not damaged and has no knots


4.2 Test process

1. Clamp the yarn sample vertically in the upper and lower clamps

2. Ensure that the yarn is not loose and is perpendicular to the fixture

3. Start the test program

4. The instrument automatically records the breaking strength value

5. Repeat the test at least 20 times to obtain reliable data


4.3 Data processing

1. Calculate the average single yarn strength

2. Calculate the strength unevenness

3. Record the maximum and minimum values

4. Generate a test report


5. Notes

1. The instrument should be calibrated before testing

2. Different types of yarn should use corresponding test parameters

3. Avoid the fixture from clamping the yarn and affecting the test results

4. The temperature and humidity of the test environment should meet the standard requirements

5. Clean the fixture surface regularly to maintain the test accuracy


6. Maintenance

1. Perform a full calibration once a month.

2. Clean the instrument surface after each use.

3. Check the sensor sensitivity regularly.

4. When not in use for a long time, the power should be turned off and covered to prevent dust.
