A Digital Yarn Twist Tester is a laboratory device used to measure the number of twists (turns) per unit length in a yarn. It’s crucial for evaluating yarn quality, strength, elasticity, and uniformity. The digital version offers precise, automated readings for both S-twist and Z-twist yarns.
Purpose Digital Yarn Twist Tester:
To determine twist per inch (TPI) or twist per meter (TPM) in single and plied yarns using direct untwist or untwist-retwist methods.
Applications Digital Yarn Twist Tester:
Quality control in spinning mills
Yarn standard testing (cotton, polyester, blends)
R&D in textile manufacturing
Working Principle Digital Yarn Twist Tester:
One end of the yarn is clamped, and the other is rotated to remove or measure twists.
The tester counts and displays twist digitally based on length and rotation.
Benefits of Digital Yarn Twist Tester:

How to Use Digital Yarn Twist Tester:
Prepare the Yarn Sample
– Cut a yarn length (e.g., 250 mm or 10 inches) as per testing standard.
– Make sure it’s free from knots or damage.
Mount the Yarn – Fix one end in the stationary clamp and the other in the rotating clamp.
– Ensure the yarn is straight and under slight tension.
Set the Gauge Length – Adjust the length scale or input it digitally, depending on the machine.
Select Twist Direction – Choose S or Z direction based on the yarn’s twist.
Start the Test – Activate the motor to untwist (or untwist-retwist, if applicable). – The display shows the number of rotations. Read the Twist Value – The twist (TPI/TPM) appears automatically based on the set length.
Stop and Unload – Once reading is complete, stop the machine and remove the yarn.
Record the Result – Note the reading for documentation or further analysis.

Fabric Stiffness Tester
Fabric Stiffness Tester
Fabric Stiffness Tester is a lab instrument used to measure the stiffness or flexural rigidity of fabric materials. It evaluates how resistant a fabric is to bending, which influences its drape, comfort, and handling characteristics. Purpose of Fabric Stiffness Tester: To determine the stiffness of textiles by measuring the bending length and calculating flexural rigidity, often using methods like the Cantilever Test (as per ASTM D1388 or ISO 9073-7). Working Principle of Fabric Stiffness Tester: A fabric strip is slid over a horizontal platform until its free end bends under its own weight to a specific angle (usually 41.5°). The length at which this occurs is used to calculate bending length and stiffness.

- Place the Sample - Lay the fabric strip flat on the test platform with one end aligned at the zero mark.
- Slide the Fabric - Gently push the fabric forward so it slowly overhangs the platform.
- Watch for Deflection - Stop sliding when the free end of the fabric bends down to the reference angle (typically 41.5°).
