FIELD: personal and household goods.SUBSTANCE: present invention relates to an ultrathin superabsorbent infant diaper that not only can rapidly absorb urine, but also effectively prevents urine leakage, providing favorable air penetration, while the diaper thickness is significantly reduced. Ultra-thin superabsorbent baby diapers contain the foundation of a baby diaper. Inguinal region of a baby diaper base comprises a surface layer, SAF fibrous nonwoven fabric with high water absorbing capacity and a layer of neutralizing a salt impregnated nonwoven SMS material, SAF with a high water-absorbing capacity is placed between the surface layer and the neutralizing impregnated salt-impregnated nonwoven SMS material. Ultra-thin super absorbent baby diapers have the following advantages: 1. nonwoven SMS material impregnated with salt is on the reverse surface of the breathable middle layer of the moisture retaining substrate, so as to ensure water resistance, effectively prevent seepage and greatly reduce the thickness of the baby diaper, while combining water impermeability, resistance to precipitation and air permeability； 2. fibrous nonwoven SAF material with high water-absorbing capacity serves as a layer of sanitary napkin, absorbent liquid, which not only significantly reduces the thickness of the sanitary napkin, but also increases the ability of the baby diaper to absorb urine, providing a child with comfort and satisfying user's requirements.EFFECT: higher ability of a baby diaper to absorb urine, providing a child with comfort and satisfying user's requirements.6 cl, 2 dwgНастоящее изобретение относится к ультратонкому супервпитывающему детскому подгузнику, который не только может быстро впитывать мочу, но также эффективно предотвращает просачивание мочи, обеспечивая благоприятное проникновение воздуха, при этом толщина подгузника значительно уменьшена.
