STRETCHABLE LAMINATE Russian patent published in 2019 - IPC A61F13/49 

FIELD: hygiene.

SUBSTANCE: present invention relates to a stretchable laminate. In particular, this invention relates to the use of a stretchable laminate in absorbent hygienic articles. Such hygiene products have enhanced elasticity, fastening properties and a better fit, which results in improved leakage protection properties due to the adjustable elastic properties of the stretchable laminate. Elasticity is adjusted by forming recesses of a definite distribution on a fabric layer without applying any elongation pre-forces to the layer and deforming it. Additionally, changing the distribution of the recessed parts provides variability of elasticity in a wide range for a wide range of materials which the fabric layer is produced from in a simple and economical manner. This method allows to obtain stretchable laminates of different elasticity by easily changing the distribution of the recessed parts without changing the dimensions and other basic physical characteristics of the fabric layer.

EFFECT: since the design parameters of the stretchable laminate are so diversified, preparation of the stretchable laminates, which have varying elastic properties, by using fixed amount/size of the fabric layer is accomplished, whereby the shape, appearance and aesthetics of the laminate is maintained.
