Pneumatic fabric stiffness tester
1. Product Introduction & Applications
The Pneumatic Fabric Stiffness Tester is designed to measure the bending properties of textiles, an essential physical parameter for evaluating a fabric’s crispness, drape, flexibility, and softness.
The instrument uses bending length (overhanging stiffness) and bending stiffness as mechanical indicators to quantify the fabric’s resistance to bending deformation, commonly referred to as fabric stiffness.
Applicable Materials:
Woven fabrics (cotton, wool, silk, linen, chemical fiber)
Knitted fabrics
Nonwoven fabrics
Coated textiles
Paper, leather, film, and other flexible sheet materials
Typical Applications:
Evaluation of textile handle and softness
Quality control for fabric stiffness uniformity
R&D testing of coating materials and technical fabrics
Comparative analysis of rigid vs. flexible sheet materials
Key Functional Advantages:
Infrared “stealth” detection slope replaces traditional mechanical slope, enabling non-contact measurement and eliminating errors caused by sample twisting.
Adjustable slope angle to meet different test methods.
Automatic pneumatic pressure plate ensures consistent sample positioning and improves testing efficiency.
Strong anti-interference performance with enhanced detection stability.
2. Conforming Standards
The Pneumatic Fabric Stiffness Tester complies with:
GB/T 18318.1-2009 — Determination of the bending length of textile fabrics
ZB W04003-87 — Fabric stiffness test method (Slope Cantilever Method)
This instrument is recommended for the above test method.
