Testing Standard
International protocols for determining the tear resistance of textiles provide a consistent framework for quality assurance in global trade. The ISO 13937-2 method uses a trouser-shaped test specimen to measure the force required to propagate a single-rip tear. This specific standard is widely adopted by Chinese flax mills to certify the durability of their export fabrics.
It ensures that the results from a laboratory in Harbin can be directly compared with those from a buyer in Europe.
Tear Resistance
Force applied to the pre-cut legs of the specimen simulates the accidental ripping that might occur during the use of a garment. During the execution of ISO 13937-2, the average force needed to continue the tear is recorded in Newtons. Linen fabrics often show different results in the warp and weft directions due to variations in yarn count and density.
High tear strength is a sign of long-staple flax and careful weaving without excessive chemical damage.
Compliance Verification
Documentation of these test results is often a mandatory requirement for the acceptance of a shipping lot. Adhering to ISO 13937-2 allows the manufacturer to prove that the linen meets the technical specifications of the contract. If a fabric fails this test, it may be rejected or downgraded to a lower price category.
Precise testing according to this international standard reduces the risk of disputes between the weaver and the garment brand.
