A Comprehensive Guide to Different Types of
EDANA NWSP Nonwoven Testing Machines
EDANA NWSP nonwoven testing machines are specialized laboratory instruments designed to evaluate the physical, mechanical and functional properties of nonwoven fabrics in strict accordance with EDANA (European Disposables and Nonwovens Association) NWSP series test standards.
Why NWSP Matters
Defines the industry: Establishes clear specifications for the properties, composition, and performance of nonwovens.
Supports global trade: Provides a common technical language across the U.S., Europe, and international markets.
Drives consistency: Ensures products can be reliably described, produced, and tested throughout the supply chain.
Recognized internationally: Many NWSP methods are adopted by ISO or CEN, further reinforcing global alignment.
Common Types of EDANA NWSP Nonwoven Testing Machines
1. Automatic Nonwovens Absorption Tester GT-CN26
Automatic Nonwovens Absorption Tester GT-CN26 is a highly automated testing instrument that uniformly evaluates the liquid absorption capacity and absorption rate of nonwoven material samples. It often applies to absorbent nonwoven products such as baby diaper core materials, sanitary napkin layers and medical dressings since the machine quantifies liquid absorption volume and absorption speed under standardized test conditions.
2. Nonwovens Absorption Tester GT-CN02
This Nonwovens Absorption Tester GT-CN02 is is used to test absorption of nonwoven, liquid absorptive capacity and liquid wicking rate.
3. Liquid Strike-Through Tester GT-CN04
Liquid Strike-through tester can be used to determine the liquid strike-through test of nonwovens such as sanitary napkins, diaper covering materials and so on. Sometimes, repeated strike-through cycles are tested to simulate real-world multiple liquid exposure conditions and evaluate long-term liquid penetration performance. Lack of efficient strike-through performance directly impacts product surface dryness and user comfort, making this kind of tester especially critical for quality control of top-layer nonwoven materials that require fast liquid conduction and lasting surface dryness.
4. Full-Automatic Fabric Stiffness Tester GT-C70A
Fabric Stiffness Tester is used to measure the fabric stiffness, in addition to determine the bending height, flexural rigidity and bending modulus of fabrics by simple procedures and calculations. This machines is mainly used in: cotton, wool, silk, hemp, chemical fiber and other types of woven fabric, knitted fabric and the generality of the non woven fabric, coated fabrics and other textiles, but also suitable for paper, leather, thin film flexible material.
5. Automatic Fabric Drapability Tester GT-C22
Automatic Fabric Drapability Tester is used to test the dynamic and statics drape property of all kinds of fabrics, include drape coefficient, lively rate, corrugated surface and aesthetic coefficient of the fabric.
Fully cyber-control drape-o-meter is designed to measure drape property from the deformation by gravity of an initially horizontal annular ring of fabrics. A circular fabric specimen is held concentrically between two smaller horizontal discs. An annular ring of fabric is allowed to drape into folds around the lower supporting disc.The shadow of the draped specimen is cast onto a sandblasted glass of same size as the un-supported part of the fabric specimen.The outline of the shadow is taken by a digital camera.The photographic will be sent to a computer to determine the shadow area with help of special software.The drape coefficient is calculated from the shadow area and original area of fabric specimen.
6. Dry State Lint Tester GT-RA16
Dry State Lint Tester to test the coefficient of linting and other particle s generation of surgical drapes, gowns and clean air suits for patients, clinical staff and equipment in the drying state.
7. Hydrostatic Head Tester for Textile GT-C26A
Hydrostatic Head Tester for Textile GT-C26A occurs when a gradually increasing water pressure is applied to one side of a nonwoven fabric sample, thus measuring the water penetration resistance and waterproof barrier performance of the material. Digital Hydrostatic Head Tester is used to testing the waterproof properties of fabrics through waterproofing work such as canvas, coated fabrics, hood fabric, tarpaulin, rain-proof fabrics and geotextile.
8. Non-woven Thickness Gauge GT-C46-3
Non-woven Thickness Gauge GT-C46-3 takes precise thickness measurements of nonwoven fabric samples under specified pressure and standard contact area conditions, causing stable and repeatable thickness data for material uniformity evaluation. Such kind of measurement is often required in incoming material inspection as well as in production process monitoring when material thickness directly influences other performance properties such as absorption, softness and tensile strength. Preventive measures for measurement deviation include regular calibration of the pressure foot and gauge sensor, standardizing sample placement procedures, or maintaining stable test environment conditions to lessen data fluctuation.
9. Single Column Tensile Strength Tester GT-C02-1
Single Column Tensile Strength Tester GT-C02-1 is a type of mechanical testing equipment in which a constant-speed vertical tensile force is applied to a nonwoven sample, to measure the tensile strength, elongation at break and tearing resistance of the material. These test parameters reflect the mechanical durability of nonwoven fabrics that make end products more resistant to deformation and breakage during processing and actual use. The single-column structure delivers compact footprint and flexible test configuration, supporting multiple test modes to accommodate different nonwoven material types and EDANA NWSP test standards.
10. Air Permeability Tester GT-C27A
Air Permeability Tester is used to test the air permeability of textile fabrics, various woven fabrics, knitted fabrics, non-woven fabrics, industrial filter materials etc.
How to Choose the Best Nonwovens Tester
In some cases, your production needs would determine the best nonwovens tester to choose. Most times, it is important to consider what products you manufacture and what testing indicators you need. Below are some important questions you should ask yourself before you choose the nonwovens tester type that suits your needs. Your response to these questions will help you determine what is best for you.
Do you need to test raw materials or finished products?
Experts have advised that incoming material inspection is best done with basic material testers to control quality at the source. Absorption, strength and softness testers are great as they cover core raw material properties. However, if you need to verify finished product performance then you should opt for hygiene product specialized testers.
Do you need to comply with international market standards?
If you really need to export products to global markets, it is necessary to select NWSP nonwoven testing machines that fully conform to ISO, ASTM, EDANA and other international standards. This is because test data from standard-compliant equipment is recognized by global markets and third-party certification bodies.
Do you have enough technical personnel for equipment maintenance?
This is an important question to ask when considering the nonwovens tester type to buy. While it is important you clean your tester after every use, some testers require tedious and professional maintenance. Such examples include precision strength testers and multi-functional finished product testers.
Can you afford a more full-featured option?
Overall, your budget speaks volume when choosing nonwovens tester type. A more full-featured and high-precision tester is a good investment in the long run. This is because you don’t have to be worried about insufficient testing capacity as your business grows. However, you can still buy a cost-effective basic tester to cover core quality control needs. Your testers can last longer with the right care and regular maintenance.
