This utility model relates to the field of personal care products technology, specifically a front-flow design structure for disposable diapers to prevent soiling. It includes a diaper body and an elastic barrier band structure positioned on the inner absorbent layer of the diaper body. The elastic barrier band structure starts from the outer side of one waist, extends through the groin area on the same side to the perineum, and then extends to the outer side of the other waist. This utility model, by setting the elastic barrier band structure in a three-dimensional "∞" shape, can divide the interior of the diaper body into independent rear and front areas. This innovative design effectively prevents feces and other stains from overflowing from the rear area to the front, avoiding the soiling spread problem common in traditional diapers. For example, during use by infants or adults, when excrement accumulates in the rear area, the elastic barrier band structure acts as a barrier.
