Non-woven material and absorbing product using it

FIELD: human vital needs satisfaction.

SUBSTANCE: non-woven material containing the first protruding portion passing to the first side of the surface in a horizontal projection of the non-woven material in the form of a sheet, and the second protruding portion passing to the second side of the surface as the opposite side from the first surface, where a plurality of the first acting portions and the second protruding portions, alternately through the wall parts, is distributed in two directions: the first direction and the second direction, in the horizontal projection of the non-woven material, where the wall part has the orientation of the fibres along the direction connecting the first protruding portion and the second protruding portion, almost anywhere in the direction of the surface defined as the first direction and the second direction.

EFFECT: improvement of the product properties.

FIELD: production of nonwoven materials, in particular, equipment for manufacture of mat from mineral filaments.

SUBSTANCE: apparatus has device for cutting of strips having predetermined length and width from thermally fixed carpet of mineral filament, means for rotation of strips through 90 deg relative to their longitudinal axis, and means for placing of turned strips in side-to-side manner in the form of laminated mat. Means for rotating of strips through 90 deg relative to their longitudinal axis has at least one cassette construction adapted for placing groups of strips in side-to-side arrangement after cutting thereof, and means for rotating cassette construction through 90 deg relative to longitudinal axis of rotation extending in parallel with longitudinal axis of strips. Apparatus is further provided with feeding cassette for placing of strips rotated by means of cassette construction. Feeding cassette has ejector located adjacent to its discharge edge.

EFFECT: increased efficiency and improved construction.

Non-woven material // 2617985

FIELD: textile, paper.

SUBSTANCE: proposed nonwoven material comprises: the first projecting section protruding from the first surface on the side in view in the nonwoven material plan as a sheet, and a recessed section, curved from the second surface on the side opposite to the first surface side. The first projecting section and the recessed section are alternately and continuously arranged by using a wall in each of various intersecting directions in a view in the nonwoven material plan, wherein the wall has a fiber orientation characteristics in the direction connecting the top part of the first projecting section and the lower section of the recessed section; in the case where the thickness of the first projecting section, including the top of the first projecting section, is defined as Ta and the thickness of the nonwoven fabric as a whole in view from the side of the nonwoven material is defined as T, the value of expression (Ta/T)100(%) is equal to 50% or more; and fibers with different fineness are included in the nonwoven material.

EFFECT: improved material properties.
