Tensile Testing of Textile Fabrics
Tensile testing of textiles provides the strength and elongation properties for both natural and manmade materials, such as cotton, carbon, polyester, nylon, glass and graphite. Textiles can be tensile tested in many forms, including single strands, yarns, webbing, woven, braided material and nonwoven fabrics. The majority of textile fabric tensile testing is performed as either a grab test, in an effort to eliminate edge effects, or a strip test, including edge effects. For a grab test, the grips clamp a fabric sample in the center using jaws smaller than the sample width. For a strip test, the grips clamp a strip of fabric using jaws wider than the sample width. For both tests, grip the specimen inside the ends of the sample length. Machines for textile tensile testing are typically low force, high elongation, constant rate of elongation or load and are table-top systems.
Tearing Strength Testing of Textile Fabrics
ASTM D5587, ASTM D2261… Etc standatd are a testing specification that determines the tearing strength of textile fabrics by the trapezoid procedure using a recording constant-rate-of-extension-type (CRE) tensile testing machine. This test method applies to most fabrics such as woven fabrics, air bag fabrics, blankets, napped, knitted, layered, and pile fabrics.
Tear strength is the capacity of a material to withstand the tearing force required to propagate a tear after its initiation. The trapezoid tear produces tension along a reasonably defined course such that the tear propagates across the width of the specimen. Tear strength can be calculated as either the single-peak force or the multiple-peak forces based on the fabric type and the tearing action observed.
Theory
Mainly Clamping the specimen.control load and speed by Electronic Control System.Inductive power through force sensor and transmitted to signal to the microcomputer systems to determine various properties of the specimen.
