This document discusses different types of strength tests for fabrics, including tensile, tear, and bursting strength tests. It describes various tear strength tests like the tongue tear test, tongue double tip test, trapezoid tear test, and ballistic tear test. The document provides details on how to perform the tongue double rip test and the trapezoid tear test. It also briefly mentions the elmendorf tearing test and different types of bursting strength tests.

12. Description

17. Tearing Strength Testing

18. • Tear Strength :Tear Strength is the force required either to start or to
continue tear in a fabric under specific condition.
• Tearing Force: Tearing force is the avg. force required to continue tear
previously started in a fabric.
• Tearing resistance: Tearing resistance is one of the important
properties of a textile fabric. The tear strength of a fabric force indicates its
resistance to tearing.

19. Types of Tear Test
1. The Tongue Tear Test
2. The Tongue Double Tip
3. The Trapezoid Tear Test
4. The Ballistic Tear Test
5. The Ring Rip Tear Test

20. Method of Measuring Tongue Tear Test

22. The Tongue Double Rip Test

24. At First Cut the Specimen (6 inch /3inch)
The Specimen Making Template is placed on the
specimen & Cut with edge AD taught BC in folds
As the jaws separate the fabric tears starting
from the ¼ inch cut
The avg. strength is determined on five specimen
in Each direction.

25. Trapezoid Tear Test

26. Ballistic Tear Test

27. The Elmendorf Tear Test
 Cut the specimen 100mm/75mm
At the middle point of the specimen a 20 mm slit
is cut
Distance between end of the slit to opposite edge
is 43mm.pendulum lever mechanism is used.

28. The Elmendorf Tearing Tester

30. Bursting Strength Test

31. Types Bursting Test
Hydraulic Burst(Mullen Type)
Ball Burst (Required special attachment in the
tester)
