Methodological Approaches to Product Testing

Protocols for Absorption Capacity Measurement

The meticulous evaluation of absorption capacity in incontinence underwear is a cornerstone of product testing. Protocols for measuring liquid absorptive capacity are critical in determining the efficacy of these products. According to the NWSP 10.1 standard, a structured approach is employed where Absorbent Distribution Layers (ADLs) are weighed, immersed, and then reweighed to calculate the percentage increase in weight, indicative of the liquid absorbed.

The process involves a precise timing sequence: immersion for 60 seconds, followed by a 120-second draining period. This method provides a quantitative measure of the product's ability to absorb and retain liquid. Furthermore, the repeatability of absorption under identical conditions is assessed to ensure consistency across multiple samples.

To complement these findings, the ISO 11948-1 method is also utilized, which gauges the maximum absorption capacity. This is achieved by placing a weighted object on the product and recording the time taken for the liquid to be fully absorbed. The mean absorption time and capacity are then calculated from multiple tests to establish a reliable average.

Test Parameter Mean Value Standard Deviation
Immersion Time 60 sec 1 sec
Draining Time 120 sec 3 sec
Absorption Time 27 sec 5 sec
Rewet Weight 3500 g 70 g

These protocols are essential for consumers seeking reliable information on the performance of incontinence products. 

pH Determination Techniques in Product Evaluation

The precision of pH determination techniques is critical in evaluating the efficacy of incontinence underwear. Accurate pH measurement is essential for ensuring skin compatibility and preventing irritation. In a recent study, the surface pH of a new diaper design was measured using a calibrated pH meter with a glass electrode. The diapers, with a mean fluid absorption capacity according to ISO 11948-1, were tested under controlled conditions.

The procedure involved loading the diapers with a synthetic urine solution and measuring the surface pH at specific intervals. Initially, the pH was rapidly reduced and remained stable for a period, indicating the product's ability to maintain an acidic environment, which is beneficial for skin health. Subsequent loadings showed a slight increase in pH, yet it remained within a range that suggests continued skin protection.

For a comprehensive understanding, the following table summarizes the pH measurements at different time intervals:

Time (minutes) Initial pH pH after 2 hours Final pH (5 hours)
5 4.5 5.6 5.6
10 4.5 5.6 -
15 4.5 5.5 -
20 4.5 5.5 -

These findings underscore the importance of incorporating pH regulation technologies in incontinence products. The ability to maintain an acidic surface pH even after multiple loadings is indicative of advanced diaper designs that prioritize skin health. 

Criteria for Assessing Rewetting and Dry-Feel Performance

In the quest to enhance the user experience of incontinence underwear, a pivotal factor is the garment's ability to maintain a dry surface, thereby reducing the risk of skin irritation. The rewetting criterion is a measure of the diaper's surface moisture post-absorption, indicating the potential for skin contact with residual moisture. This is quantitatively assessed by the rewet value, which is the difference in weight of the diaper when wet versus dry, expressed as a percentage of the dry weight.

To accurately gauge this performance, a structured approach is employed. For instance, after applying a 70 mL saline solution, the rewet value is measured at 30-minute intervals. The initial rewet value might be low, indicating minimal surface moisture, but a subsequent application can reveal the product's ability to handle multiple wettings. The acquisition time, or the duration taken for the liquid to be fully absorbed, is also a critical metric, with faster times correlating to better performance.

The following table summarizes the results from a recent study:

Time After Saline Application (min) Rewet Value (mg/cm2) Acquisition Time (sec)
30 1.2 44
61 2.9 N/A

These findings are instrumental in the ongoing development of incontinence products that not only prioritize absorbency but also ensure the comfort and skin health of the wearer.
