Method of forming fibrous product

FIELD: hygiene.

SUBSTANCE: present invention relates to method and device for forming fibrous product, involving following steps: 1) passage of formed fibrous product through calender, comprising vacuum drum and opposite calender shaft, on surface of which, at least one groove is located, configuration of which allows to give volumetric contour to formed fibrous product; 2) embossing calendering of fibrous product in embossing calender between first and second rollers without use of bearing layer. Thus produced fibrous product can be used as layer of absorbent core of disposable hygienic products, such as sanitary napkins, daily linings, diapers, etc. Present invention also relates to disposable hygienic products, base for making of which is formed fibrous product, made in compliance with principles of present invention.

EFFECT: use of bearing layer complicates production of products, and if bearing layer must be added to end product, it may cause increase of cost of end product and(or) negatively affect hygroscopic properties of product, therefore method and device for forming fibrous product allows to avoid above disadvantages.
