The key technology at the core of diapers is the "core body". In terms of technology, the diaper core has undergone three revolutions so far: the first was the birth of disposable diapers half a century ago; The second is the application of polymer absorbent materials in diapers in the 1980s, so that the liquid absorption performance of the product is fully guaranteed. The mainstream brands in the market are widely used in the second generation of core body. However, this kind of traditional core still has some technical limitations in absorption speed, anti-seepage degree, thickness and core strength, so that the baby red butt, reverse seepage leakage and other problems have not been solved.
Domestic and foreign diaper manufacturers are stepping up research and development of a thinner, more reliable liquid absorption performance, dry surface of the diaper, 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 entered the mature application stage. This kind of core has higher absorption efficiency and stronger toughness, and comprehensively solves the major problems of traditional second generation core. Some say the introduction of the E-core technology marks a new era for the diaper industry, and it is the first time since diapers were invented in the West that a Chinese company has taken the lead in the overall technology race.
