How to measure the twist of the yarn

How to measure the twist of the yarn:

Measurement of a twist:

There are different methods of measuring yarn twists. However, which of these methods will be used when depends on the following factors:

1. Experimental objects.

2. Accuracy of result demanded.

3. Form of the test material.

4. Amount of material.

How to measure the twist of the yarn:

The method of measuring twist has a special effect on the measurement of twist in the following matters. Therefore, to get the right result, it is necessary to consider the following issues:

1. Sampling:

The amount of twisted yarn is not the same everywhere. Usually, there is more twist in thin areas of yarn and less twist in thick areas. So if you test the twist with the yarn of your choice, you will not get the right result. Therefore, the sample that will be taken to measure the twist from a long thread should be taken at least a 1-yard interval. That means at least 1 yard of yarn should be omitted while doing two tests side by side. At least 20 of the 10 yarn packages need to be tested. Test samples are usually taken 10 inches. https://bdfabric.com/role-of-yarn-on-fabrics-properties/

2. Withdrawal of yarn from the package:

The yarn should be removed from the yarn package in such a way that it does not affect the yarn. The examination has shown that if the yarn is pulled from the side of the package, the twist of the yarn will change, but if it is pulled from one side, the twist of the yarn will not change. Care must also be taken to ensure that the yarn is handled less when transferring the yarn from the package to the testing device. So when pulling the yarn out of the package, it should be held outside the test length. https://bdfabric.com/finishing-process-in-textile-wet-processing/

3. Pull on the test yarn:

The tension of the parasitic object can affect the twist of the yarn. Therefore, standard tension must be maintained while measuring the twist. Standard Tension 2 +/- 10% grams/tex.

Twist measurement instruments:

There are various types of instruments used for measuring yarn twist, Such as

1. The ordinary twist tester.

2. The continuous twist tester.

3. Twist contraction method.

4. Take-up twist tester.

5. The quadrant twist tester.

6. Twist measurement by microscope.
