    • 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. The papermaking felt is made by stacking and intertwiningly integrating by needling a substrate, a first batt fiber layer disposed on the wet paper web side of the substrate, and a second batt fiber layer disposed on the machine side of the substrate; wherein the substrate is made from a plurality of reinforcing materials, the reinforcing materials include a spunyarn, and due to the intertwining with a batt fiber layer, the spunyarn is integrated to such a degree that the yarn shape disappears.
    • 一种造纸机,其在造纸机中具有良好的挤压能力(透水性)和对扁平化的耐久性,并且还具有优异的湿纸幅平滑性能和抗纤维损失。 造纸毡是通过针刺衬底,设置在衬底的湿纸幅侧上的第一絮垫纤维层和设置在衬底的机器侧上的第二胎层纤维层进行堆叠和交织的一体化而制成的。 其特征在于,所述基材由多种增强材料制成,所述增强材料包括纺丝纱,由于与毛层纤维层相互缠绕,所述纺丝纱一体化,使得纱线形状消失。
