What is bursting strength test?
Bursting strength test is a mechanical test used to measure the strength and durability of woven fabrics. It is an important parameter in assessing the quality and performance of woven fabrics, as it provides information about the fabric’s ability to withstand pressure and resist bursting or tearing under mechanical stress.
The bursting strength test is typically conducted using a specialized instrument called a bursting strength tester or a hydraulic bursting strength tester. The test involves applying pressure to a fabric specimen until it bursts, and the maximum pressure required to cause the fabric to burst is recorded as the bursting strength.
The basic principle of the bursting strength test involves clamping a circular or square-shaped fabric specimen securely between two circular plates or jaws of the bursting strength tester. A hydraulic or pneumatic pressure is then applied gradually to the specimen until it bursts. The pressure required to burst the fabric specimen is measured and recorded as the bursting strength, typically expressed in units of pressure, such as pounds per square inch (psi) or kilopascals (kPa).
The bursting strength of a fabric is influenced by various factors, including the type of fiber, yarn construction, fabric construction (such as weave or knit structure), and fabric finish or treatment. Higher bursting strength values generally indicate stronger and more durable fabrics that are less likely to burst or tear during use or processing.
Bursting strength testing is widely used in the textile industry for quality control, product development, and performance evaluation of woven fabrics, such as apparel fabrics, upholstery fabrics, and technical textiles. It helps textile manufacturers ensure that their fabrics meet the required standards and specifications for their intended end-use applications and helps in the development of fabric designs with optimal performance characteristics.
What is bursting strength of woven fabric?
Bursting strength for woven fabric refers to the maximum pressure or force that a fabric can withstand before it bursts or tears. It is a measure of the fabric’s strength and durability, indicating its ability to resist bursting or tearing under mechanical stress.
Bursting strength is typically measured using a specialized instrument called a bursting strength tester or a hydraulic bursting strength tester. The test involves applying pressure to a fabric specimen until it bursts, and the maximum pressure or force required to cause the fabric to burst is recorded as the bursting strength.
The bursting strength of a woven fabric can vary depending on various factors, including the type of fiber used, yarn construction, fabric construction (such as weave or knit structure), fabric thickness, and fabric finish or treatment. Higher bursting strength values generally indicate stronger and more durable fabrics that are less likely to burst or tear during use or processing.
Bursting strength values for woven fabrics are typically reported in units of pressure, such as pounds per square inch (psi) or kilopascals (kPa), or in units of force, such as pounds or newtons (N), depending on the testing standards and specifications used.
Bursting strength testing is an important parameter in assessing the quality and performance of woven fabrics and is widely used in the textile industry for quality control, product development, and performance evaluation of fabrics for various end-use applications, such as apparel, home textiles, upholstery, and technical textiles. It helps textile manufacturers ensure that their fabrics meet the required standards and specifications and helps in the selection of fabrics suitable for specific applications based on their bursting strength characteristics.
