FIELD: textiles, paper.SUBSTANCE: in a nonwoven fabric a plurality of small fibrous fragments, having a deeper colour than the colour of the basic texture of the nonwoven fabric, is distributed and placed in a scattered state over the whole area of the nonwoven fabric. In addition, the value difference (T3) of thicknesses is 1 mm or less when determining according to the formula T3=T1-T2, where T1 is the thickness of the nonwoven fabric (10) in determining under the pressure of 7.64 kPa in the area where there is a fine fibrous fragment, while T2 is the thickness of the nonwoven fabric determined under the pressure of 7.64 kPa in the area where the fine fibrous fragment is absent.EFFECT: improvement of the efficiency of manufacturing the nonwoven fabric.23 cl, 4 dwg, 2 tbl |
