Perspiration Tester

A Perspiration Tester is a lab device used to evaluate the colorfastness of textiles to artificial perspiration (sweat). It simulates the effects of human sweat—both acidic and alkaline—on dyed or printed fabrics under controlled temperature and pressure.

Purpose of Perspiration Tester:

– To test how fabrics react to body sweat and determine whether dyes bleed, fade, or transfer onto adjacent materials.

Working Principle:

Fabric samples are treated with synthetic perspiration solution (acidic or alkaline).
They are sandwiched with adjacent fabric and placed between glass or acrylic plates.
The assembly is loaded into the tester and pressed under specific pressure.
it’s then incubated at 37°C (body temperature) for a fixed time (typically 4 or 16 hours).
Afterward, color change and staining are evaluated using a gray scale.

Applications of Perspiration Tester:

– Garment and sportswear testing

– Quality control in textile processing

– Compliance with standards like ISO 105 E04, AATCC 15

Benefits of Perspiration Tester:

Accurate Sweat Simulation – Mimics real-life effects of acidic and alkaline perspiration on fabrics.
Improves Product Quality – Ensures textiles retain color and don’t bleed or stain when worn.
Supports Standard Compliance – Follows ISO and AATCC test standards for global market approval.
Protects Brand Reputation- Reduces customer complaints due to dye transfer or fading.

Simple and Repeatable- Provides consistent pressure and conditions for reliable results.
Multi-Sample Testing- Tests multiple specimens at once, saving time in labs.
Durable and Low Maintenance- Robust frame with minimal moving parts makes it long-lasting and easy to care for.

Features of Perspiration Tester:

Stainless Steel Frame – Corrosion-resistant body for durability and long-term use.
Multi-Sample Capacity – Can hold up to 20 or more specimens for batch testing.
Standardized Loading Weight- Applies uniform pressure (usually 12.5 kPa) across all samples.
Removable Plates – Glass or acrylic plates ensure even contact and easy cleaning.

Compact Design- Space-saving, bench-top model ideal for lab environments.
Complies with Test Standards – Meets ISO 105 E04, AATCC 15, and related perspiration fastness standards.
Ease of Operation – Simple loading, unloading, and incubation process.
High-Temperature Resistance – Can be used inside incubators at 37°C or ovens as required.

How to Use a Perspiration Tester:

Prepare the Test Solution – Mix artificial acidic or alkaline perspiration as per standard (ISO or AATCC).
Cut the Fabric Samples – Cut both the test fabric and adjacent white fabric (usually cotton) to standard size.
Soak the Samples – Immerse the fabric sandwich (test + adjacent) in the test solution for 30 minutes.
Remove Excess Liquid – Gently squeeze or blot to remove extra moisture—do not dry.

Load in the Tester- Place each sandwich between glass or acrylic separator plates in the tester.
Apply Pressure – Tighten the top plate or place the standard weight on top to apply uniform pressure.
Incubate – Keep the loaded tester in an oven or incubator at 37°C for 4–16 hours (depending on the method).
