During the 1950s, companies such as Kendall, Parke-Davis, Playtex, Adult Diaper and Molnlycke entered the disposable diaper market. In 1956, Procter & Gamble began researching disposable diapers. Vic Mills, along with his design battery including William Dehaas, both men who worked for the company, invented "Pampers" while searching for a more desirable product to use.
Over the next few decades, the disposable diaper corporation boomed and the contest between Procter & Gamble's Pampers and Kimberly Clark's Huggies resulted in lower prices and drastic changes to diaper design. Hardly Any 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 obvious as sodium polyacrylate.
