Three classic tests of sanitary napkins

The combustion test, the water absorption experiment, and the breathable impermeable test are the three classic tests that are performed on sanitary napkins.

The primary objectives of the combustion test are the following: to differentiate between plant fiber and chemical fiber; When plant fiber is burned, no black smoke is produced, and the byproduct after it has been completely consumed by flame is similar to carbon ash. During the process of burning chemical fiber, black smoke and a burned smell are produced, and the substance ultimately transforms into jelly. Not easy to break down.

The main purpose of the water absorption test is: good water absorption can let you do not have to worry about the amount of Menstrual blood leakage to the underwear, or stick to the skin.

The primary objective of the Breathable and Waterproof Bottom Film Test is: Check the permeability of the bottom film, because if the sanitary napkin is not breathable, it will lead to the breeding of bacteria in the female private parts due to humidity; Impermeability is primarily intended to demonstrate that the bottom membrane of the sanitary napkin will not allow the menstrual blood absorbed by the sanitary napkin to leak back into the underwear. Keep your underwear clean.
