Perspiration Tester Operation Manual

Perspiration Tester

Perspiration Tester Usage Background：

When there was a reaction between dye clothes and discharged from the body, it may cause discoloration or color change of clothes, such as perspiration. It is because the situation is different individuals and conditions are not the same faded, stained material was measured in case of perspiration fading of methods have been established ISO, AATCC, and other different standards to measure. In some cases, depending on the conditions are more faded clothes, plus a final concentration of sweat accumulation and reaction with the sun is believed to be the reason such a situation, causing the dye structure some elements impact. Such a case, the component prediction method of sweat (acidic and alkaline pH) under different conditions of these proposed standards.

Perspiration Tester Introduction:

Perspiration Tester is widely used to test textiles of the color fastness to perspiration, such as sea water, saliva and distilled water. The colored textile specimen is wet out using a simulated acid perspiration solution or others, and placed in contact with a multi-fiber strip. Extrusion to remove excess liquid of the combination, then subjected to a fixed mechanical pressure for a pre-determined period. Following incubation, the Perspirometer is removed and specimens and multi-fiber strip are observed the charge of color after drying respectively. Stainless steel sample holder that can accommodate 20 samples with acrylonitrile partition plate, while providing AATCC, ISO, BS and other standard weight

Perspiration Tester Operation Manual:

PH test shall be performed on different instruments in order to avoid a chemical reaction, and produce erroneous test results.

1.    Loosen the rotating screw for AATCC Perspiration Tester, along the main support bar to raise roof assembly

2.    Remove 21 acrylonitrile partition plates, and place the prepared samples between adjacent plates. The sample was placed on the partition plate to ensure that the instrument into the oven after the multi-fiber cloth fabric with vertical test. This prevents the flow of other dye fabric tape fabric tape. The appropriate number of samples has been installed partition plate mounted on the instrument. And reacted with a guide rod is flush with the back of the instrument.

3.     Set the last piece of acrylonitrile in the partition plate, the hole will align the top plate assembly main support bar, slid along the main supporting rod uppermost partition plate

4.     The tests specified in the standard weight placed on the top plate assembly by rotating the rotating screw to lock the roof in place. Spring means samples can occur during drying shrinkage pressure changes provide compensation to ensure constant state sample

For the instrument migration test is required 4.5kg (10 lb) of additional weight to ensure that the pressure 9.1kg (20 lb). Gellowen can provide the additional weight

5.     Weight is removed, the combination of instruments loaded into the oven. It is heated in the oven for a period of time (depending on the relevant test standard). Then, remove from the oven and allowed to cool. Loosen the rotating screws and remove the top plate assembly

Warning: Due to the roof assembly under tension, operation of loosening the screw should be careful.

6.     After the sample composition is completely dry, carefully remove it, and then according to the test criteria to evaluate discoloration, staining and changes and other phenomena produced

7.     Clean the instrument and acrylonitrile partition plate, so as to maintain a neutral state

Perspiration Tester Equipment maintenance and repair:

Although AATCC perspiration tester requires only a small amount of maintenance, it is still the instrument and acrylonitrile partition plate washing and neutralization, solvent or prevents its dye staining, or cross-contamination. Typically, the instrument needs to be kept clean and free of dust optimum operating condition. Acid and alkali dish to note the use of separate

Perspiration Tester Instrument characteristics:

The machine adopts high-quality stainless steel processing;

Plywood moves flexible, low friction;

Concealed design, pressure spring hide all;

Upper and lower jaws are used grinder for processing, effectively ensuring the flatness;

Moving plywood with a guide post slider;

Sample plywood is smooth and no glitches.

Perspiration Tester Factors:

①fabric kinds, the fabric is usually different acid and alkali resistance;

② Kinds of dyes, dye there are many kinds of dyes, such as acidic, basic, reactive dyes, and so perspiration reaction is not the same;

③Fixed dye manner,

④ Fabric finishing way

⑤ Other additives

⑥ Type of perspiration
