Textiles, yarn, thread, fabrics, wool, cotton, and other animal and plant-derived fibers are commonly tested to make sure product quality by assessing the performance of materials and ensuring they're acceptable towards proper end-use. This blog post will cover certain mechanical testing methods to check fabric and re-evaluate the testing standards also because the recommended equipment.

Tension Testing
Tensile testing is that the most ordinarily applied test method for analyzing the mechanical properties of cloth materials. Although the direction of applied force is usually in tension, there are a spread of tensile test methods available for capturing the foremost relevant data for final product usage.
The strip test may be a tensile test during which the complete width of the test specimen is gripped within the tensile grip jaws of a universal testing machine. During this test, tensile force is applied on the material specimen until it ruptures. Mechanical properties to research include the force at rupture and therefore the elongation (expressed as percentage) at maximum force and/or at rupture.
Testing standards which will be followed to run strip tests include:
A grab test may be a tensile test during which the middle a part of the specimen width is gripped within the tensile grip jaws. thanks to the way the sample is gripped, edge effects, which can cause inaccurate data for fabrics, are eliminated. almost like the strip test method, tensile force is applied to the material specimen until rupture and maximum force is recorded. Fabric specimens most frequently tested using the grab method are woven and non-woven textile fabrics.
Testing standards outlining grab test instructions include:
ASTM D751 – Standard Test Methods for Coated Fabrics (Breaking Strength, Procedure A)
ASTM D1683 for woven apparel fabric seams
ASTM D2208 for soft, boarded, sueded, or embossed leather
ASTM D5034 – Standard Test Method for Breaking Strength and Elongation of Textile Fabrics (Grab Test)
ISO 13934-2
