Abstract
A weft-water type n-shaft papermakers' fabric has a running side surface and a papermaking side surface, in which n is an integer of at least 6. The fabric has warps and wefts forming the running side surface, the wefts consisting of both short crimp-forming wefts, which cross two or more warps, and long crimp-forming wefts which have a length more than 1.5 times the length of the short crimp. The improvement in crimpiness permits the use of large wefts having a large diameter. The arrangement of the running side surface does not affect the papermaking side surface of a double layer, triple layer or other multilayer weave.
