AN INSTALLATION FOR INVESTIGATING THE MIXED FABRIC STRETCHING DEFORMATION

Abstract

A setup is proposed for studying the elongation of mixed fabric samples under uniaxial tension. The setup allows todetermine the absolute and relative elongation of mixed fabric samples at various values ​​of a gradually increasing load, as well as the fabric samples at the time of their rupture. The values ​​of the breaking load and the cross-sectional area of ​​the samples at the rupture point determine their breaking mechanical strength. On the proposed installation, one can test samples of mixed fabrics of sizes 25 ∙ 100 and 50 ∙ 100 mm in the direction of the warp and weft, as well as samples of homogeneous fabrics and knitted fabrics.
