1056 Improvements to Eco-Friendly Sanitary Napkins made from Natural Fibres: Development and Characterization paper, a weighing machine, and a stopwatch were needed for this test. Blotting papers with known beginning weights were inserted on top and bottom of the pad, respectively, after weighing the sanitary napkin and identifying the leak's position. A standard weight of 1 kg was placed across this fluid-absorbed area for 1 minute. At the end of the loading time, the top and bottom of the pad are taken out in order to calculate the ultimate weight of the serviette and blotting sheets.The retention percentage measured how much blood the sanitary napkin could hold after absorbing it when 1 kg of weight was applied. The retention% was calculated using the formula: Retention% = ((FR-IN)/ (IN))*100 Where IN- napkin Initial weight FR- napkin final weight The sanitary napkin's ability to contain absorbed blood from its sides and bottom when one kilogramme of weight is applied is known as the leak factor. The leak factor was calculated using the formula: Leak factor% = ((FTB-ITB)/ (ITB))*100 Where ITB- top blotting paper Initial weight FTB- top blotting paper Final weight The rewet under load is the ability of the sanitary napkin to resist leaking of the absorbed blood from the top of the sanitary napkin on application of 1 Kg weight. The Rewet under load was calculated using the formula: Rewet under load% = ((FBB-IBB)/ (ITB))*100 Where IBB- bottom blotting paper Initial weight FBB- bottom blotting paper Final weight 2.2.3 Techniques for evaluating the performance of the sanitary napkins in the made-up performance tester A performance tester, test fluid, and a stop clock were used to conduct the testing. The aforementioned procedures were followed in order to utilise the fictitious performance tester. The integrated load cell made it unnecessary to take out the sanitary napkins from the apparatus each time the weight of the apparatus needed to be measured, making the process easier and more precise than with the previously mentioned internal approach. Initially, the load cell controller is nullified to guarantee the accurate measurement. The exact centering of the burette was confirmed. The glass plate was placed on top of the sample sanitary napkin. The liquid was released from the burette at a rate of 15 drops per minute, with a distance of 1 to 2 millimetres from the sanitary napkin. Furthermore, there is a reservoir that will provide the liquid to the burette during the testing procedure, removing the need to empty the burette and add more liquid. The electronic weighing balance will show the weight of the sample. The stop clock was configured to run each time the time component required to be measured and reported. The weighing lever was skewed inward to the top of the napkin's centre, and the liquid reservoir holder was turned sideways to measure the fluid retention capacity. The sanitary napkin's rewet under load and leak factor might be measured by placing blotting paper over and below it before adding weight. To calculate weight, sanitary napkins and blotting sheets were weighed separately before being placed on the base plate. The sanitary napkin's performances were computed.
