To effectively test the absorbency of sanitary napkins,various standardized methods and equipment are utilized.Here’s a summary of the key practices and methodologies involved in conducting absorbency tests:

Absorbency Testing Methods

Water Absorbency Tester:

The Sanitary Napkin Water Absorbency Tester(GT-CN20)is a specialized device used to determine the water absorption capacity of sanitary napkins.It can test multiple samples simultaneously and provides automatic weighing and result calculations.The testing parameters include:

Measuring Range:0 to 1000g

Test Stations:Up to 5

Temperature Control:Room temperature to 45°C

Testing Speed:1 to 900 mm/min.

Laboratory Test Method No.H-5:

This method involves submerging the sanitary napkin in a 1%saline solution for a specific time(typically two minutes)to measure how much liquid it absorbs.The steps include:

Weighing the dry specimen.

Partially submerging it in saline solution.

Weighing it again after removal to calculate the absorbed weight.

The absorbency rate is calculated as the difference between the wet and dry weights,indicating how effectively the product can keep users dry.

EDANA Guidelines:

The European Disposables and Nonwovens Association(EDANA)provides guidelines for testing feminine hygiene products,including absorbency tests that assess both absorption capacity and retention under pressure(wetback).These tests help evaluate how well products perform in real-life conditions.

IS 5405 Standards:

In India,the Bureau of Indian Standards outlines specific requirements for sanitary napkins under IS 5405.This includes testing for absorbent fillers,ensuring they do not leak under specified conditions,and verifying that they meet size and comfort specifications.

Evaluation Criteria

Absorbency Capacity:Indicates how much liquid a pad can hold before leaking.

Wicking Ability:Measures how quickly liquid spreads through the material.

Retention Capacity:Evaluates how much liquid remains in the pad when pressure is applied,which is crucial for comfort and preventing leaks.

pH Level:Ensures that the product maintains a neutral pH to avoid irritation.
