Tensile Test of Fabrics (JIS L 1096 Strip Method)

Introduction

People change clothes every day, depending on the season, time of day, circumstances, and scene. For example, on a summer day we might wear a T-shirt with good permeability for air, but in cold winter weather, we would wear a down jacket with a high heat-retaining property. People who work at actual worksites wear work clothes that are made of sturdy material and allow easy movement. Thus, various types of performance are required in clothing, depending on which value that the wearer prioritizes, e.g. comfort, functionality, or design, and new products are appearing daily to meet these needs. Since clothing is a product, strength evaluation is necessary in order to maintain a certain quality. JIS L 1096 : 2010 not only provides methods for measuring the tensile strength and tear strength of the woven and knitted fabrics that are indispensable in our daily lives, but also describes various evaluation methods for the permeability of fabrics to air and their heat-retaining property. Among these, the JIS and ISO methods include a total of 6 test methods for tensile strength. There are 4 JIS methods, method A (strip method), method B (grab method), method C (wet strip method), and method D (wet grab method), and 2 ISO methods, method E (strip method) and method F (grab method). This article introduces an example of a tensile test of fabric specimens by method A (strip method).
