What is BS EN 29073-3 – Nonwovens about?
BS EN 29073-3 is an international standard that focuses on the best quality of nonwoven fabrics.
BS EN 29073-3 specifies a method for the determination of the tensile properties of nonwovens by the cut strip method.
BS EN 29073-3 covers technical specifications such as the principle of the test method, apparatus used, sampling of the test specimen, preparation and conditioning of test pieces, procedure, expression of results, etc. for determining the tensile strength and elongation of nonwoven fabrics.
Note: Anomalies can occur when testing some spun-laid and glass fibre nonwovens. This may require modification of the test procedure.
Who is BS EN 29073-3 – Nonwovens for?
BS EN 29073-3 on tensile strength and elongation of nonwovens is useful for:
- Textile manufacturer
- Clothing industries
- Textile testing laboratories
- Regulatory authorities
- Quality control personnel
- Research and development facilities
Why should you use BS EN 29073-3 – Nonwovens?
Nonwovens are innovative, high-tech, engineered fabrics made from fibres. The trapezoid tear method is a test that produces tension along a defined course such that the tear generates across the width of the specimen. Although nonwovens are classified within the textile industry, it should be recognized that nonwovens technologically share characteristics not only with textile products but also with paper and plastic products.
BS EN 29073-3 gives you a test method to determine the tensile strength and elongation of nonwovens. It specifies the method of sampling the test specimens of an approximate length. This ensures you that the fabrics are of good quality and free from any flaws.
BS EN 29073-3 determines the elongation of the test piece at the maximum breaking strength and expresses this as a percentage of the nominal gauge length, that is, the original jaw separation.
Thus, BS EN 29073-3 helps the users to manufacture and enhance the quality and longevity of the nonwoven fabrics.
