Woven Fabric Weight Tolerances and Linear Metre Yield Calculations
Reconcile woven fabric purchases by calculating linear yield from conditioned mass and usable cuttable width under ISO 3801 and ISO 139 parameters.
Tensile Strength Iso 13934
Fabric Strength
An international testing standard determines the maximum force and elongation of woven textile fabrics using strip or grab methods in a laboratory environment. Quality control laboratories apply tensile strength iso 13934 to verify that finished fabrics meet the minimum strength requirements specified by clothing brands. This standard is not intended for knitted or nonwoven materials.
Testing Protocol
The test involves securing a strip of fabric of specific dimensions between the clamps of a tensile testing machine. As the clamps move apart at a constant rate, the machine records the force until the fabric ruptures. This measurement provides objective data on fabric performance.
Material Response
Warp and weft directions are tested separately because fabrics usually exhibit different strengths along these axes. When analyzing results under tensile strength iso 13934, engineers evaluate both the breaking force and the elongation at break. High tensile strength prevents the seams from tearing under stress during garment wear.
This property is crucial for workwear and technical apparel that undergo intense physical strain. The testing must be done under standardized temperature and humidity conditions.
Commercial Compliance
Buyers use these test results to accept or reject fabric shipments from mills. Fabric that fails to meet the specified strength limits is rejected before it can be cut and sewn. This preventive check protects the brand’s reputation.
