    摘要： A method of seaming an on-machine-seamable multiaxial papermaker's fabric to prevent yarn migration. The multiaxial fabric is in the form of an endless loop flattened into two layers along fold lines. CD yarns are removed from the folds to create ravel areas. This leaves the MD yarns unbound in the ravel areas. Seam loops are then formed from the unbound MD yarns at the folds. A thin porous material is sewn to the fabric at each fold. The porous material binds the CD yarns along the edges of the ravel areas while allowing passage of the seam loops through the material. The laminate prevents migration of CD yarn tails into the seam area.
