Abstract: A composite forming fabric woven to a repeating pattern in at least 6 sheds; up to at least 36 sheds can be used. All of the paper side layer warp yarns are pairs of intrinsic warp binder yarns (101, 102) occupying an unbroken warp path in the paper side surface including three segments. The first and a second are occupied in turn by each intrinsic warp binder yarn (101, 102), and the third by both intrinsic warp binder yarns (101, 102) of a pair. The first, second and third segments are separated by at least one paper side layer weft, and a first or second segment is adjacent each end of the third segment. Within each first and second segment, each intrinsic warp binder yarn (101, 102) also interlaces once with a machine side layer weft (2′, 9′), at the same point as a machine side layer warp (103) interlaces with the same weft (2′, 9′). The weave path occupied by each member of a pair of intrinsic warp binder yarns (101, 102) can be the same or different.

Abstract: A method for manufacturing a loop pile fabric with a varied appearance includes a woven backing fabric. Loop weft yarns (12A), (12B) are provided outside the backing fabric, and loop warp yarns (1), (2), (3) are so provided that they are alternately inwoven in the backing fabric and form a pile loop (13), (14) over at least one loop weft yarn (12A), (12B), and the loop weft yarns (12A), (12B) are subsequently removed. By providing first (12A) and second loop weft yarns (12B) with a different thickness, pile loops (13), (14) of different height are formed. To obtain a fabric in which both pile loops (13) and cut pile (15) occur subsequently a top part can be removed from a number of pile loops (13). In areas (19) where no pile loops are formed effect backing weft yarns (11B) with laterally protruding filaments can be inwoven in the backing fabric. A loop pile fabric can be manufactured according to this method.
