Product development: reusable diaper

Product development is usually a response to an existing problem in a product, or it is identifying users' needs in order to ameliorate the living conditions of people or to enhance life in general. Some patients with certain ailments and geriatrics in general usually have an incontinence problem. Disposable products are available at relatively expensive price and not easily available for certain people or for financially marginalized people, and yet there is need for these products. This research was done to develop an affordable, re-usable product for adults who have an incontinence challenge. Terry cloth was used as an absorbent fabric for the future product and three water repellent fabrics were tested for water repellency and bleaching, prior to designing and evaluating the product. All three fabrics were water repellent and only one was resistant to chlorine bleach used in the development of this product. The chlorine resistant fabric was used in constructing the adult washable nappy. When the prototype was evaluated from user trials, it received approval when used with durable laundry gloves and machine washed. Generally, the design was approved for use by individuals with an incontinence problem and thus recommended for public use.

Development of fabric using chemically-treated sisal fibres

The aim of this study was to explore the spinnability of sisal fibres treated with sodium hydroxide (NaOH), and the potential utility of spun yarns in producing a woven fabric for different end uses. Exploratory and experimental approaches were utilised in gathering data for this project. Yarns were spun using a spinning wheel, and subsequently a portable weaving loom was used for weaving the fabric. Fabric softeners were applied on the woven fabric, and later fabrics were evaluated for hand and potential end uses. Major findings revealed that sisal fibres treated with NaOH were successfully spun into yarns using a traditional spinning wheel with the aid of a binding agent. Yarns spun from treated fibres were finer, weaker and highly absorbent. Flexural rigidity was the only significant fabric property that was decreased for fabric made from treated fibres compared to the control fabric. The application of fabric softeners had no significant effect on fabric hand. Subsequently, potential end uses of woven fabric were identified, which included apparel and accessories.
