A Comparative Analysis of Tear Strength Methods

Fabric utility parameters most often depend on its mechanical properties. The most important strength parameters include unidirectional tensile strength, tear strength and elasticity properties. In this work we describe in detail the problem of tear strength, appropriate measurement methods and the correlation relationships between the results obtained by different tear methods. The measurements of tear strength were carried out for a chosen group of protective textiles. In addition, the unidirectional tensile strength was measured for the group of textiles mentioned above, and the correlation coefficients between the tensile strength and tear strength were calculated by different methods.
