Nonwoven fabrics having a fibrous background portion (12) in one plane thereof and raised fibrous portions (16; 18) in another plane thereof. There may be two types of raised portions (16; 18) in one type, the basis weight of the raised portion (16) is substantially the same as the basis weight of the background portion (12). In another type of raised portion (18), the basis weight is greater than the basis weight of the background portion (12). The raised portions (16; 18) are joined to the background portion (12) by a fibrous transition region (22; 24). IMAGE
