三层成形网在纸机上的应用已经有20多年的历史。三层网包括面层(成形层)和底层(磨损层)两个网面,这两层由一系列的缝合纱线(中间层)连接在一起。面层通常采用优质纱线以优化成纸性能,而底层通常采用线径较粗的纱线,以提高成形网稳定性和耐磨性。当成形网从单层、双层发展到高纤
Three-layer forming machine in the paper machine has been used for more than 20 years of history. The three-layer net consists of two meshes, the top layer (forming layer) and the bottom layer (wear layer), which are joined together by a series of stitching yarns (middle layer). The top layer is usually made of high-quality yarn to optimize the performance of the paper, while the bottom is usually used thicker diameter yarn to improve the stability and wear-resistant forming nets. When the forming network from single, double development to high fiber
