The digital Elmendorf tearing instrument is mainly used for the determination of the tear strength of various woven fabrics (Elmendorf method) for the detection of textile, woven fabrics, nonwovens, coated fabric impact tear strength, Can also be used for silk, cotton, all kinds of paper, cardboard and single and multi-layer corrugated board resistance to breaking strength test. digital fabric elmendorf tearing strength tester Tearing mechanism In this paper, we discuss the tear breaking process of the fabric by the single-slit method [2], which is discussed along the weft tearing of the fabric and the warp fracture. In the single seam method tear, the formation of a ripple at the force of the triangle. When the weft of the force in the sample is gradually separated up and down, the warp yarns that are not directly stressed begin to slide relative to the wefts of the force and move closer together to form an approximate triangular area. At the bottom of the tearin
