    • The object of the present invention is to provide a papermaking felt which, in a papermaking machine, has good water squeezing capability (water permeability) and durability with regard to flattening and which also has excellent wet paper web smoothing properties and resistance to fiber loss. A papermaking felt made by stacking and intertwiningly integrating by needling a substrate (200), a first batt fiber layer(300) disposed on the wet paper web side of the substrate and a second batt fiber layer (310) disposed on the machine side of the substrate; wherein the substrate (200) is made from a plurality of reinforcing materials, the reinforcing materials comprise a spunyarn (51), and due to the intertwining with a batt fiber layer, the spunyarn (51) is integrated to such a degree that the yarn shape disappears.
    • 本发明的目的是提供一种造纸毡,其在造纸机中具有良好的挤水能力(透水性)和平坦化的耐久性,并且还具有优异的湿纸幅平滑性和抗纤维损失性。 通过针刺基材(200),布置在基材的湿纸幅侧的第一棉絮纤维层(300)和布置在基材的湿纸幅侧的第二棉絮纤维层(310),通过堆叠和缠绕整合而制成的造纸毡 基材; 其特征在于,所述基材(200)由多种增强材料制成,所述增强材料包括纺丝纱(51),并且由于与棉絮纤维层缠绕在一起,所述纺丝纱(51)被集成到使得所述纱线 形状消失。
