About This Product
Perspiration fastness is a standard test for dyed and printed textiles, because sweat can change the colour of a fabric or stain the cloth next to it. A specimen is placed between two undyed fabrics, treated with an acidic or an alkaline test solution, and pressed between plates under a fixed load. The loaded frame is then kept in an oven at a set temperature for a set time. Afterwards the colour change and the staining of the white fabrics are assessed against grey scales. Students use the perspirometer to learn how colourfastness is graded.
Frequently Asked Questions
Q1. What does the Perspirometer test?
It is used to determine the colourfastness of dyed or printed fabrics against perspiration, by exposing the sample to alkaline and acidic reagents while in contact with undyed fabrics on both sides.
Q2. What are the technical data?
Test specimens measure 10 cm × 4 cm, the force on the specimens is 5 kg, and the sixteen acrylic plates measure 11.5 cm × 6.0 cm each.
Q3. At what temperature is the test run?
The specimens, held between two white adjacent fabrics and placed between plates under a fixed load, are kept in a hot air oven maintained at 37 °C.
