NWSP 090.1.R0 (20) Nonwoven Fabrics Stiffness Test NWSP 090.1.R0 (20) is a harmonized nonwoven standard procedure developed by INDA‑EDANA. It tests the stiffness performance of nonwoven fabrics. The standard evaluates fabric stiffness by the cantilever test principle. It applies to a wide range of nonwoven materials, including untreated, sized, coated and resin‑treated nonwovens. Stiffness refers to the resistance of fabric against bending deformation. Appropriate stiffness improves product hand‑feel, shaping performance and handling property for nonwoven goods. Specific content of NWSP 090.1.R0 (20) standard The NWSP 090.1.R0 (20) standard describes how to test nonwoven fabric stiffness via cantilever method. It covers test principle, specimen requirements, sampling, conditioning atmosphere, apparatus specifications, operating steps and calculation rules. The standard ensures tests are consistent and comparable across laboratories. It also provides a reliable basis for assessing the bending performance of nonwoven fabrics in global nonwoven tradeINDA. Application of the NWSP 090.1.R0 (20) standard The NWSP 090.1.R0 (20) standard is widely used in the production and quality control of nonwoven textiles. It applies to most nonwoven fabrics. It also sets a harmonized testing benchmark for international nonwoven fabric trade. Related equivalent standards include ISO 9073‑7, ASTM D 1388, GB/T18318 and BS EN22313. Testing principle of NWSP 090.1.R0 (20) NWSP 090.1.R0 (20) defines stiffness testing by cantilever principle. It measures the overhang length of rectangular specimen which slides forward on horizontal platform, when the specimen tip bends down under its own weight and touches the 41.5° inclined reference plane. Bending length can be derived from measured overhang length, then flexural rigidity and bending modulus can be calculated. The stiffer the nonwoven sample, the longer overhang length it presents. Test results cover bending length, flexural rigidity and bending modulus. Machine direction (MD) and cross direction (CD) shall be tested separately for anisotropic nonwoven materials. Test Methods of NWSP 090.1.R0 (20) Standard For stiffness tests, use professional instruments, such as full‑automatic fabric stiffness tester GT‑C70A. The Cantilever Tester for fabric stiffness pushes rectangular specimen forward at fixed feed rate. It records overhang length when specimen tip reaches the 41.5‑degree inclined plane. Then the instrument computes bending length, flexural rigidity and bending modulus automatically. Manual cantilever devices are also acceptable if they fully satisfy the standard precision requirements. Factors affecting the results of the NWSP 090.1.R0 (20) standard NWSP 090.1.R0 (20) test results depend on several factors. These include the specimen’s fiber composition, fabric structure, bonding condition, coating or resin finishing, basis weight and thickness. The lab technician must handle the specimen carefully during the test,...

Nonwovens Absorption Testing: ISO 9073-6 VS NWSP 010.1.R0 (20) If you want to know how fast a disposable wipe can absorb spilled liquid, or how much fluid a medical dressing can hold without leakage, or how quickly liquid spreads across a nonwoven fabric in practical use, then you must go with the nonwovens absorption test. A hygiene nonwoven with a fast absorbency time and high absorptive capacity can easily handle daily use scenarios. Nonwovens buyers and manufacturers heavily rely on this test to ensure the fabric’s ability to handle liquid exposure in real-world applications. What Is the Role of the Nonwovens Absorption Tester for Consistent Results? The Non-Woven Water Absorption Tester gives a simulation of real-world liquid contact scenarios, and it operates on standard parameters that are defined by international organizations such as ISO and EDANA. GESTER’s Automatic Nonwovens Absorption Tester GT-CN26 and Nonwovens Absorption Tester GT-CN02 both adopt high-precision sensing systems and automated control programs, which help the operator get accurate and repeatable test results. Is it essential to do Standardized Testing for Nonwovens Absorption? To perform standardized testing, we have two widely recognized standards, ISO 9073-6 and NWSP 010.1.R0 (20), which provide consistency when performed over different labs. Both standards are internationally recognized and provide comprehensive details regarding test procedures, including specimen preparation, test conditions, operation steps, and result calculation methods. Actually, these standards help the manufacturers as well, because if they have to make the product that can meet a specific absorbency time or capacity requirement, then it means after quality production, their product will meet this index in every country’s lab. The nonwovens buyers buy the product with confidence after seeing the standardized absorption test results. So, in this way, the standardized testing eliminates the guesswork and gives authentic data. ISO 9073-6 The International Organization for Standardization (ISO) provides standard testing methods to measure the liquid absorption properties of nonwoven fabrics under ISO 9073-6. The ISO 9073-6 standard specifically defines standardized test methods to determine the absorption performance of nonwovens.
