Nonwovens Testing Equipment Guide –

ISO 9073 for Nonwovens

Brief Background of the Standard System

The entire ISO 9073 system applies to all mainstream nonwoven production processes, without restrictions on fiber raw materials (polypropylene, polyester, viscose, cotton blended, biopolymer fibers).

Mask coverstock, disposable protective garment outer layer, agricultural mulch nonwoven – tested for air permeability, tensile strength and water repellency.

High-efficiency filtration core material, medical mask filter layer – key test items include air flow resistance and lint generation per ISO 9073-10.

Guide to Selecting Qualified ISO 9073 Nonwovens Testing Equipment

Following the ISO 9073 full-series test specifications, all nonwoven production factories, hygiene product labs, medical material manufacturers and third-party inspection institutes need matching dedicated Non-woven Fabrics Testing Instruments to complete standardized testing of basis weight, tensile strength, absorbency, air permeability,
hydrostatic pressure, lint loss, softness and other core indicators.

GESTER nonwovens testing machines listed below comply with corresponding clauses of ISO 9073 standard series, supporting automatic sampling, fixed standard test parameters, digital data recording and ISO-compliant test report output. Below is the detailed equipment matching guide classified by ISO 9073 test items:

1. Automatic Nonwovens Absorption Tester GT-CN26

This fully automatic absorption tester is designed for testing liquid absorbency capacity, wicking rate and demand absorbency of all types of nonwovens, including spunlace wipes, hygiene top sheet nonwovens and composite absorbent core materials.

2. Nonwovens Absorption Tester GT-CN02

Semi-automatic cost-effective absorbency testing instrument for small laboratories and factory incoming inspection lines. It completes basic absorbency capacity measurement of nonwoven fabrics, featuring compact footprint, simple operation and stable data repeatability, ideal for preliminary screening of nonwoven raw materials with low daily test volume.

3. Liquid Strike-Through Tester GT-CN04

Specialized tester for strike-through time, repeated strike-through performance and wetback rewet volume of disposable hygiene nonwovens such as diaper coverstock and sanitary pad surface fabrics. It simulates human body liquid contact status as required by ISO 9073, accurately recording penetration duration and reverse osmosis liquid volume to evaluate skin-friendly performance of absorbent nonwovens.

4. Full-Automatic Fabric Stiffness Tester GT-C70A

Used to test bending length and bending stiffness of spunlace, spunbond and needlepunched nonwovens, evaluating material softness. Widely applied for medical dressing substrates, facial mask nonwovens and wiping cloths, with automatic angle measurement and digital stiffness value output that fully conforms to ISO 9073 softness evaluation rules.

5. Automatic Fabric Drapability Tester GT-C22

Measures drape coefficient of all nonwoven materials, judging material compliance for protective clothing, isolation gown and decorative nonwoven fabrics.

6. Dry State Lint Tester GT-RA16

Professional dry lint loss testing machine for meltblown filter nonwovens, mask raw materials and automotive interior nonwovens.

7. Hydrostatic Head Tester for Textile GT-C26A

Core barrier performance testing equipment for medical protective nonwovens including surgical gowns, isolation coveralls and mask outer layers.

8. Non-woven Thickness Gauge GT-C46-3

High-precision thickness measuring instrument exclusive for nonwoven fabrics. Equipped with standard pressure measuring head defined by ISO 9073, it accurately tests thickness of spunbond, meltblown, spunlace and needlepunched nonwovens, supporting fast batch measurement for raw material incoming inspection.

9. Single Column Tensile Strength Tester GT-C02-1

Multi-functional mechanical performance tester for nonwovens, covering grab tensile strength, trapezoid tear resistance, ball burst strength and strip breaking strength test items. Adjustable stretching speed, standard fixture clamps and built-in data calculation system satisfy mechanical property testing requirements of all nonwoven types under ISO 9073 series.

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.
