Fabric Stiffness Tester
Fabric Stiffness Tester is a lab instrument used to measure the stiffness or flexural rigidity of fabric materials. It evaluates how resistant a fabric is to bending, which influences its drape, comfort, and handling characteristics.
Purpose of Fabric Stiffness Tester:
To determine the stiffness of textiles by measuring the bending length and calculating flexural rigidity, often using methods like the Cantilever Test (as per ASTM D1388 or ISO 9073-7).
Working Principle of Fabric Stiffness Tester:
A fabric strip is slid over a horizontal platform until its free end bends under its own weight to a specific angle (usually 41.5°). The length at which this occurs is used to calculate bending length and stiffness.
Main Components of Fabric Stiffness Tester:
– Test Platform: Flat surface for sample movement.
– Graduated Scale: Measures the overhanging length of fabric.
– Angle Indicator: Guides the measurement based on standard deflection angle.
– Fabric Clamp or Guide: Helps place and move the sample smoothly.

How to Use Fabric Stiffness Tester (Cantilever Method):
- Prepare the Sample – Cut the fabric into a rectangular strip (e.g., 25 mm × 200 mm), as per standard.
- Place the Sample – Lay the fabric strip flat on the test platform with one end aligned at the zero mark.
- Slide the Fabric – Gently push the fabric forward so it slowly overhangs the platform.
- Watch for Deflection – Stop sliding when the free end of the fabric bends down to the reference angle (typically 41.5°).
- Read the Bending Length – Measure the overhang distance from the scale. This is the bending length (C).
- Calculate Flexural Rigidity
– Use the formula:
G = W × C³
Where:
– G = Flexural rigidity (mg·cm)
– W = Fabric weight per unit area (mg/cm²)
– C = Bending length (cm)

Fabric Moisture Permeability Tester
A Fabric Moisture Permeability Tester, also known as a Water Vapor Permeability Tester, is a laboratory instrument designed to measure the rate at which water vapor passes through textile materials. This measurement is crucial for assessing the breathability and comfort of fabrics, especially those used in active wear, outdoor gear, medical textiles, and protective clothing. Purpose of Fabric Moisture Permeability Tester The primary function of this tester is to evaluate a fabric's ability to allow moisture vapor to pass through it, which directly impacts the wearer's comfort by facilitating sweat evaporation and thermal regulation. High moisture permeability indicates better breathability, making the fabric suitable for applications where moisture management is essential. Working Principle of Fabric Moisture Permeability Tester The tester operates by placing a fabric specimen over a container filled with water. Under controlled temperature and humidity conditions, water vapor passes through the fabric over a specified period. The amount of water vapor transmitted is determined by measuring the weight loss of the container, allowing for the calculation of the Water Vapor Transmission Rate (WVTR). Common Testing Methods- Upright Cup Method: The fabric covers a cup containing water, and the assembly is placed upright in a controlled environment. After a set duration, the weight loss is measured to determine the WVTR.
- Inverted Cup Method: The fabric is sealed over a cup, which is then inverted and exposed to a controlled environment. The amount of water vapor absorbed by the fabric is measured over time.
- Sweating Hot Plate Test: Simulates human perspiration by measuring the energy required to maintain a constant temperature on a heated plate covered with the fabric, providing insights into the fabric's breathability.

- Start the Test - Begin rotation (usually ~2 RPM) and let it run for the specified time (often 24 hours).
- Weigh the Cups Again- After the test duration, reweigh the cups to determine weight loss due to moisture vapor passing through the fabric.
