The evolution of baby diapers from one to three generations

The core key technology of diapers is the 'core'. From a technical point of view, the core body of diapers has experienced three revolutions so far: the first was the birth of disposable diapers half a century ago; the second was the application of polymer absorbent materials in diapers in the 1980s. The liquid absorption performance of the product is fully guaranteed, and the second-generation core is commonly used by mainstream brands in the market. However, this kind of traditional core body still has certain technical limitations in terms of absorption speed, anti-reverse osmosis degree, thickness and core strength and toughness, etc., so that the problems of baby red bottom and reverse osmosis side leakage have not been solved completely. Diaper manufacturers at home and abroad are stepping up the development of a lighter, thinner, more secure diaper, and a dry surface. There are also some semi-mature products on the market. Until the second half of 2012, the E-core phased diaper series was launched, announcing that the third core technology innovation has entered the mature application stage. This kind of core has higher absorption efficiency and stronger toughness, and comprehensively solves the major problems of the traditional second-generation core. Some commentators said that the advent of 'E-core' technology symbolized the development of the diaper industry into a new era. This is the first time that a Chinese company has achieved a leading position in the technology competition since the invention of diapers in the West.
