A lofty non-woven web 40,62 having x,y and z directions, which correspond to the machine direction, the cross machine direction, and the loft direction respectively, comprises a plurality of continuous fibres 46 which are orientated in the z-direction and are folded to form loops 48 that are'U'-shaped and which aggregate in the cross machine direction to form waves extending across the web with a succession of waves spaced apart in the machine direction. The bight of the "U" 50 may extend either in the machine direction (x) with the legs 52,54 extending to the upper and lower surfaces 42,44 of the web, or in the loft direction (z) with both legs 69 extending to the same surface 64 , preferably retrograde of the bight 68. The non-woven webs further comprise an absorbent. |
