FIELD: private hygiene articles. SUBSTANCE: absorbing material has laminated structure comprising at least one layer with relatively high moisture permeability on upper side contacting with user's body and at least one layer with relatively low moisture permeability. This layer has structure with capillary surface tension within the range of 1-5 cm, with capillary surface tension difference from the top to the bottom being at least 1 cm. Absorbing material has layer with moisture permeability of at least 1,000 darsi and layer with moisture permeability below 1,000 darsi, with difference between higher moisture permeability and lower moisture permeability layer values being 250 darsi. Laminated structure has drainage rate for first entry of below 30 ml for 100 ml of excreta released at the rate of 20 ml/s. Absorbing material allows excreta to be effectively held and may be used in private hygienic articles such as diapers, isolating clothing, absorbing underwear, articles for grown up people suffering incontinence of urine, etc. EFFECT: simplified structure and wider range of use. 24 cl, 1 dwg, 3 tbl, 7 ex
