MULTI-LAYER NON-WOVEN FABRIC FOR ABSORBENT PRODUCTS Russian patent published in 2022 - IPC A61F13/514 

FIELD: absorbents.

SUBSTANCE: multilayer nonwoven fabric according to the present invention includes a layer 20 obtained from a blown melt and a layer 10 obtained by a die method superimposed on one or two surfaces of the layer 20 obtained from a blown melt, and the diameter of the fibers, which are fibers 21 forming the layer 20 obtained from a blown melt, it is less than 1 mcm. The multilayer nonwoven fabric according to the present invention is such that the ratio t_max/t_min, which is the ratio of the maximum thickness t_max to the minimum thickness t_min of the layer 20 obtained from the blown melt, is more than 2, or the occupancy level, which is the degree of filling of the space with fibers, is more than 7.7%. In each fiber 11 forming the layer 10 obtained by the die method, the ratio of fiber sizes in the horizontal cross-section of fiber 11 is more than 1.2.

EFFECT: expansion of the range of solutions for the production of absorbent products.
