STUDYING THE EFFECTS OF SOME STRUCTURAL PARAMETERS ON THE TENSION STRENGTH AND ELONGATION AT BREAK OF WEFT KNITTING FABRIC

Abstract

The study was conducted with the aim of evaluating the influence of textile materials and some structural parameters such as thickness, weight, density on
the break load and elongation at break of weft knitting fabrics. In this study, the authors use three fabric samples with the following compositions: 70% bamboo/
20% polyamide/ 10% spandex, 100% polyamide, 80% bamboo/ 20% polyamide, provided by local manufacturers for testing. Experimental research methods
were used to: Determine the weight of fabric (g/m2
) according to TCVN 8042:2009; Determine fabric density according to TCVN 5794:1994; determine fabric
thickness according to TCVN 5071:2007, determination of breaking load and elongation at break according to TCVN 5795:1994. The experimental results were
synthesized and analyzed using Microsoft Excel. The experimental results were synthesized and analyzed to compare and analyze the data obtained for each
sample of test cloth and the results showed that the higher the fabric weight, density, and thickness, the greater the break load and elongation at break; Among
the tested samples, the fabric containing spandex exhibited the highest tensile break load and elongation at break.
