Development and Research on Incontinence Underwear for the Elderly

Zhu Chunyan, Zhou Baixue, Bi Yanwei, Pan Li, Yang Chen

Fibres & Textiles in Eastern Europe

2024

Vol. 32, no. 1

40--52

This study investigates the living conditions of elderly individuals with urinary incontinence and their usage of related products to assess their actual needs, including comfort, convenience, and affordability. Based on these findings, innovative design work was conducted, involving structural design, fabric preparation, and process selection. Ultimately, through product performance evaluation and refinement, the design requirements for comfort, convenience, and affordability were achieved. This research holds significant importance in addressing urinary incontinence issues among the elderly and can be applicable to individuals with restricted access to toilets or those engaged in prolonged activities. Furthermore, the study provides a valuable reference for designing and developing functional garments that cater to practical needs. With further production and market promotion, this research outcome is expected to yield greater value and impact on a larger scale.

Effect of preparation method and polymer impregnation on form stability of expanded perlite/paraffin composite

Interest in the use of phase change materials in construction materials is constantly increasing. However, the problem is to develop an effective method to introduce them. The challenge is to obtain shape-stabilized composites with a high heat storage capacity. In this paper, expanded perlite was proposed as a potential carrier of phase change material (paraffin). The effectiveness of two impregnation techniques - vacuum and immersion - was compared. Composites with various amounts of paraffin were prepared, and then their properties were characterized. It has been shown that the vacuum impregnation method can be used to obtain composites with better shape stability. Despite this, leakage was observed in the materials with high proportions of paraffin. It was been proven that, regardless of the impregnation method, the application of a thin polymer dispersion coating can effectively protect the composite against leakage of the phase change material. Thanks to the use of epoxy resin, a stable composite was obtained with a paraffin content of over 80% by weight. The high PCM content and no leakage effect during the phase transition make the presented composite show great potential for many different applications.
