| description | ABSTRACTTextile waste materials such as chemical-based diapers are responsible for aggravating environmental pollution. It usually takes years to degrade naturally. The world is in constant need of some green alternative solutions without compromising on product performance. Cellulosic materials being highly absorbent and biodegradable in nature such as cotton, Kapok, jute, banana etc. have the potential to replace these synthetic materials. The present study investigates the simulated urine absorption and retention characteristics of 100% cotton and Kapok-cotton blended webs. The morphological characteristics of raw, scoured and rewetted Kapok fiber were first studied. The hollow Kapok fiber lumen was found to have collapsed after scouring. However, it regained its shape after re-wetting in simulated urine. Absorption capacity was found to be maximum at 50:50 Kapok-cotton ratio in the nonwoven web. Statistically, the t-test also corroborates the same result at a 5% significance level. The absorption rate (g/s) and retention (%) were also maximum for the same blend. With an increase in external pressure, the liquid retention was reduced. On comparing a 50:50 Kapok-cotton blended with a 100% cotton nonwoven fibrous web, the absorption capacity, rate, and retention are increased by 26.1%, 300%, and 13.5%, respectively. |
