The utility model relates to the technical field of paper diapers, and provides a
urine and excrement partitioned baby paper diaper, which solves the problem of baby
diaper rash caused by design defects of the existing paper diapers, and comprises a paper diaper body, a front
waist area corresponding to the front side of a
human body, a rear
waist area corresponding to the rear side of the
human body and a connecting area connecting the front
waist area and the rear waist area are arranged on the paper diaper body, a plurality of front side flow guide grooves are formed in the front waist area, a plurality of middle flow guide grooves are formed in the connecting area, and a plurality of rear side flow guide grooves are formed in the rear waist area. Each front side flow guide groove is connected with each middle flow guide groove, and at least two front side flow guide grooves are connected with each rear side flow guide groove through each middle flow guide groove; by designing different numbers of the front flow guide grooves and the rear flow guide grooves, the flow guide and absorption characteristics of the front area of the paper diaper are higher than those of the rear area, and when an infant urinates and defecates,
urine is prevented from flowing to the rear area to be mixed with excrement, so that
diaper rash is avoided.
