    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:

    1. Fabric samples are treated with synthetic perspiration solution (acidic or alkaline).
    2. They are sandwiched with adjacent fabric and placed between glass or acrylic plates.
    3. The assembly is loaded into the tester and pressed under specific pressure.
    4. it’s then incubated at 37°C (body temperature) for a fixed time (typically 4 or 16 hours).
    5. 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:

    1. Accurate Sweat Simulation – Mimics real-life effects of acidic and alkaline perspiration on fabrics.
