Background portion is positioned in first plane of fabric and raised portion is positioned in second plane, above first plane, in parallel with it. Raised portion is connected to background portion through intermediate portion defined by filaments. Basic weight of raised portion coincides with basic weight of background portion. According to another version, nonwoven fabric is of the same kind as previous version, with the exception of basic weight of raised portion that exceeds basic weight of background portion, with both portions being of equal density. Other version of nonwoven fabric involves plurality of filaments and has background portion disposed in first plane, and first and second raised portions disposed in second plane, above first plane in parallel with it. Each raised portion is connected to background portion through transition portion made from filaments. Fabric has distinctly expressed raised portions defining distinctly expressed pattern.
