摘要
The present invention relates to a process for producing an absorbent structure, preferably for use in an absorbent article such as a diaper, a sanitary napkin, a sanitary napkin, a saliva-absorbing element and the like, which comprises dry-forming a pneumatically deposited cellulosic fibrous material to a first density of 0.2 to 1.0 g / cm3. The essence of the invention is that the pressed sheet-free process is mechanically loosened to a second, lower density and, during loosening, spaced-apart areas (63) separated by layers of fibers (62) of the same density as the first are formed. The present invention relates to a water-absorbent structure (11, 21, 41, 51) which is preferably used as an absorbent pad for an absorbent article such as a diaper, a sanitary napkin, a sanitary napkin, an incontinence pad, a bed cover, a wound or other wound dressing, a saliva absorbent or the like. the first density in the dry-formed range of 0.2 to 1.0 g / cm3 is formed from a sheet of cellulosic fibrous fur material. The essence of the absorbent structure according to the invention is that the sheet contains 5 to 100% by weight of cellulose fibers and consists of a first density fiber layer (62) and spaces (63) formed between them by further mechanical loosening of the bases, and the absorbent structure (11, 21, 41, 51 ) is second, with a density of up to 75% lower than the first, and weighs between 30 and 2000 g / m2. The invention further relates to an absorbent article such as a diaper, a sanitary napkin, a sanitary napkin, an incontinence pad, a mattress, a wound or injury cover member and the like, comprising a liquid-permeable topsheet (12, 22, 42, 52) and a liquid-impermeable backsheet (13). , 23, 43, 53) and an insert formed as an absorbent structure (11, 21, 41, 51) interposed therebetween. The essence of the invention is that the insert is formed of the absorbent structure (11, 21, 41, 51) according to the invention. ŕ
