The decision to use cloth or disposable diapers is a controversial one, owing to issues ranging from convenience, health, cost, and their effect on the environment. Currently, disposable diapers are the most commonly used, with Pampers and Huggies being the most well-known brands in the industry. Plastic pants can be worn over diapers to avoid leaks.
Over the next few decades, the disposable diaper industry boomed and the competition between Procter & Gamble's Pampers and Kimberly Clark's Huggies resulted in lower prices and drastic changes to diaper design. Several improvements were made, such as the introduction of refastenable tapes, the "hourglass shape" so as to reduce bulk at the crotch area, and the invention of super-absorbent material from polymers known as sodium polyacrylate.
