FIELD: textile industry. SUBSTANCE: nonwoven material has repeat pattern composed of interlaced fibrous zones. First fibrous zone has plurality of parallel fibrous segments. Second zone has a number of twisted and turned fibrous segments defining strip extending perpendicular to parallel fibrous segments of first fibrous zone. Second fibrous zone adjoins first fibrous zone. Nonwoven material has third fibrous zone for connecting first and second fibrous zones. Third fibrous zone has a plurality of highly entangled fibrous segments. Nonwoven material has uniform absorption characteristics in all directions of fabric surface. According to second version, material has uniform absorption characteristics and, as a result, pattern of absorption of liquid on fabric has average index of at least 0.6. Absorption pattern has even perimeter, with average index of its form being at least 0.7. According to third version, nonwoven material has uniform absorption characteristics and sine-shaped curve of filament distribution over its section area. Average percentage of filament covering area in fabric section multiplied by 1/2 of average number of maximum and minimum filament covering points per cycle and divided by average amplitude of filament distribution curve is at least 600. EFFECT: provision for obtaining improved relatively uniform absorption characteristics without deteriorating other required properties of nonwoven material. 12 cl, 10 dwg |
