FIELD: production of nonwoven elastic absorbing materials with improved compatibility at low loading levels, in particular, group of inventions including combination of nonwoven elastomeric single filaments, cellulose filaments and superabsorbing material. SUBSTANCE: first structure is made from elastic absorbing nonwoven material comprising, at the rate of material weight, from 3 wt% to about 20 wt% of matrix of elastic single thread including multiplicity of thermoplastic elastomeric nonwoven single filaments, and about 20-77 wt% of absorbing filaments and about 20-77 wt% of superabsorbing material, which are embedded inside matrix. Second structure is absorbing hygienic article comprising elastic absorbing nonwoven material including, at the rate of material weight, about 5-18 wt% of matrix of elastic single thread involving multiplicity of thermoplastic elastomeric filaments, and 25-70 wt% of absorbing filaments and 25-70 wt% of superabsorbing material, which are embedded inside matrix. Third structure is absorbing medicinal article comprising elastic absorbing nonwoven material including, at the rate of material weight, about 5-18 wt% of matrix of elastic elementary thread involving multiplicity of thermoplastic elastomeric nonwoven filaments, and about 25-70 wt% of absorbing filaments and about 25-70 wt% of superabsorbing material, which are embedded into matrix. EFFECT: improved compatibility at low loading levels and increased absorptive capacity of said structures, reduced production costs and wider range of usage. 24 cl, 1 tbl |
