Discussion on quantitative testing method for flexibility of textile-based stab-proof material
The flexibility and wearability of the stab-proof material are subjectively evaluated at present,and there is no quantified flexible performance index and testing method standard.In this paper,two testing methods for the flexible performance of stab-proof material,vertical pressing method and plane pressing method,were discussed from the evaluation of the force and deforma-tion of the materials in the use cases.50 N as the constant load force was applied to test the deformation rate and surface radian of the material,or 100 mm as the constant deformation was used to test the force loaded on the material in the case of the vertical pressing method.The plane pressing method took the pressure value of the material pressed to a depth of 20 mm.
