Clothes are prone to wear and tear from the moment they are purchased. This is due . Every day, many of these actions cause serious wear and tear on our clothes. Therefore, the importance of testing the tear strength to ensure better quality products delivered to customers cannot be overemphasized. Tear strength Testers are reliable instruments for determining the tear .
What is the tear strength of the fabric?
The force that starts to tear the cloth in the weft or warp direction under certain conditions is defined as the tearing force. Rips in fabric or clothing usually occur along a straight line and may be caused by a moving cloth caught over a sharp object. Tear strength testing plays an important role in the textile industry in determining the quality of fine garments. This will help ensure that textile manufacturers are delivering good products to their customers by testing them for wear .
When a piece of cloth is hooked by a sharp tool, with a little force, the momentary little hole punch turns into a long slit . This may be considered a fabric strength failure. This is especially important in industrial textiles that are subject to a lot of wear. ( eg tents, sacks, parachutes, etc.) Low tear strength will be evaluated in various applications such as tapes, bandages, etc. Therefore, with a tear Tester, you will be able to test the effect of forces that can cause the quality of the fabric to tear. The tear resistance test, also known as tear strength, is used to determine the ability .
How to take the tear strength of the fabric?
A tear Tester can simply be used to measure the tear strength of textiles. This test tool is not only suitable for the textile industry, but also for other industries. The test will be performed under the exact conditions when the tearing force is transferred to the specimen. With this testing device, you can quickly analyze the tear resistance of fabrics.
You can follow the steps below:
Lift the fan pendulum until it rests on the release catch pin on the left.
Open the two jaws and insert the test sample between the jaws so that it is centered between the two jaws and the bottom edge of the sample is in contact with the bottom edge of the jaws.
Tighten the jaws in the same position. When loaded, the long side of the specimen should be parallel to the top of the jaws and the transverse yarn should be perfectly perpendicular to the top edge of the jaws.
Push the knife holder, cut a slit in the specimen, and raise the knife holder until the knife holder rises further.
Lower the knife to its initial position.
Move the pointer until it rests on the zero setting block. Press the brake release lever to release the fan pendulum.
Hold the brake release lever until the tear is complete, then release the brake release lever as you swing back.
Read the scale to the nearest whole division. Reject the reading if the sample slips or tears more than 6 mm from the projection of the original slit in the grip .
Reject the reading and repeat the test with a fresh sample by fully tightening the sample and cleaning the jaws. Repeat the test until at least five warp and weft specimens are tested. Any readings that differed by more than 9% from the mean were rejected.
