Development of reusable urine leak-proof underwear with an innovative knitted fabrication

Abstract

Urinary incontinence is a considerable health issue that affects people's quality of life worldwide, many of them are female [1]. The development of reusable urine leakproof underwear is a significant innovation in solving the problems faced by people with urinary incontinence. Two main features that contribute to the effectiveness of these undergarments are absorbency and wicking properties. High absorbency, less bulk, and quick dry properties are desirable qualities in fabrics preferred for the inner layer of urine leakproof underwear [2]. Absorbency in textiles is critical to a fabric's capacity to take in urine and prevent leakage to outerwear. There are urine leakproof undergarments with multiple layers on the market, including disposable and reusable materials. Those garments can absorb substantial quantities of urine. However, it had less absorbency capacity and bulk products. According to the previous literature, consumer requirements for a urine leakproof undergarment were identified, and a solution for it [3]. The construction of this urine incontinence underwear often features a specialized layer that enhances absorbency, less bulk, quick drying, and a comfortable fit [4]. This design ensures leak-proof protection and comfortability by using seamless bonding technologies. Furthermore, the moisture-wicking ability of polyester-cotton spacer fabric actively absorbs the urine from the polyester side and quickly dries by entering urine into the cotton side.[3] Then, cotton yarns absorb urine rapidly and spread the gusset area evenly. With this innovative knitted fabric, polyurethane-coated polyester fabric was attached by bonding to the gusset area to ensure leakproof protection. Water retention v-fold bonding tape is used to achieve better leakproof protection of this gusset. Cotton-polyester spacer fabric is knitted to achieve performance such as high absorbency, less bulk, and quick dry properties [5]. When a drop of urine is released, it enters the fabric through the polyester side and absorbs that urine from the cotton side of the innovative fabric. This developed fabric enhances the lightweight quality of our urine leakproof undergarment by seamlessly integrating multiple layers for improved performance compared to existing products. Hence, reusable urine incontinence ladies’ underwear was developed with high absorbency and less bulk after developing the prototypes and testing their functionalities. Also, innovative fabrication has been engineered to significantly enhance the absorbency and comfort of undergarments while fulfilling the current trend in the textile industry.
