The invention relates to a needle punched papermaking felt. The felt includes a plurality of layers of relatively easily woven endless foundation fabrics consisting of synthetic filament yarns, synthetic fiber spun yarns, synthetic-natural fiber blended spun yarns or two or more kinds of those yarns. Batts, consisting of synthetic fibers and/or natural fibers, are laid over one or both sides of the foundation fabric. In accordance with the invention, the component fibers are caused to be entangled with each other by needle punching. The invention also relates to a method for making the felt which method includes the steps of weaving a plurality of relatively easily woven endless foundation fabrics, setting up the foundation fabrics to a needle punching machine under tension and supplying and laying batts consisting of synthetic fibers and/or natural fibers over the layers of foundation fabrics while the layers of foundation fabrics are advanced. The combined layers of the foundation fabrics and the batts are then needle punched so that the component fibers are caused to be entangled with each other. |
