It is used to test the resistance to repeated flexing damage of coated fabrics. This machine is the De Mattia test method. The resistance to repeated flexing damage of the covered fabric is tested. This machine is the De Mattia test method. DRK516A fabric flexing tester is used to test the resistance to repeated flexing damage of coated fabrics. This machine is the De Mattia test method. Standards compliant: GB/T 12586 (Method A De Mattia), ISO 7854, BS 3424:Part9 Test principle: The two ends of the strip sample formed by folding a rectangular coated fabric twice are clamped in two opposite clamps. One of the clamps reciprocates in its vertical direction, causing the coated fabric to bend repeatedly, thereby causing folds on the specimen. This folding of the coated fabric continues until a predetermined number of cycles or significant failure of the sample occurs. Technical parameter: 1. Fixture: 6 groups 2.
