| 摘要 |
The present invention relates to a method for producing a web of an elastic non-woven composite material (24) comprising the following steps: Feeding and delivering a first non-woven layer (4, 4a) in a longitudinal direction (L); feeding a plurality of elastic filaments (6); connecting the plurality of elastic filaments (6) to a first side (70) of the non-woven layer (4, 4a) to form a composite material (14); at least in some regions overstretching of the first non-woven layer (4, 4a) in the longitudinal direction (L) by feeding the composite material (14) through the gap of a pair of profiled, intermeshing stretching rollers (15), by which the composite material (14) is stretched in the longitudinal direction (L), wherein the elastic filaments (6) are arranged in the non-woven composite material such that they are substantially oriented in the longitudinal direction (L), so that they have at most 10 intersecting points with each other per cm2. The invention also relates to a non-woven composite material produced by said method, and a pant-shaped hygienic article (60) having such non-woven composite material. |
