Prueba de tracción de las telas (método de agarre JIS L1096)

Introducción

People wear different types of clothing every day to match the season, time of day, and setting. Highly breathable T-shirts are worn on hot summer days and down jackets with excellent warmth retention properties are worn on cold winter days. People doing physical labor wear work clothes made of durable fabric that allows freedom of movement. Depending on the feature that takes priority, such as comfort, functionality, or design, different performances are needed and new clothes are being created every day according to such requirements. Woven products must undergo strength evaluation to ensure they meet a certain level of quality. JIS L1096 (2020) describes various techniques for evaluating woven and knitted fabrics that are an essential part of daily life; these include test methods to measure not just breaking strength and tearing strength, but also air permeability and warmth retention. JIS L1096 (2020) specifies six different methods for breaking tests conforming to JIS and ISO. Four JIS methods includes method A (strip method), method B (grab method), method C (wet strip method), and method D (wet grab method). Two ISO methods includes method E (strip method) and method F (grab method). This article describes an example case in which a tensile test of fabrics was performed by method B (grab method).
