FELT FOR HIGH-SPEED VACUUM CYLINDER PAPER MACHINE

FELT FOR HIGH-SPEED VACUUM CYLINDER PAPER MACHINE

A felt for a high-speed vacuum cylinder paper machine. The felt comprises, sequentially connected from top to bottom, a front-layer fiber web (1), an intermediate-layer fiber web (2), a base web (3), and a back-layer fiber web (4). The front-layer fiber web (1), the intermediate-layer fiber web (2),...

description A felt for a high-speed vacuum cylinder paper machine. The felt comprises, sequentially connected from top to bottom, a front-layer fiber web (1), an intermediate-layer fiber web (2), a base web (3), and a back-layer fiber web (4). The front-layer fiber web (1), the intermediate-layer fiber web (2), the base web (3), and the back-layer fiber web (4) are shaped by means of needling. Each layer of the felt is made from fibers having a specific fineness and the base web (3). The felt has a good dehydrating capabilities, and reduces the occurrence of the felt rewetting the paper, thereby improving the dryness of a wet sheet in an outgoing nip, and reducing steam consumption. The steam consumption is reduced by 10% when compared to a conventional felt, and the felt of the invention has higher tensile strength, and a long service life. The base web is prepared by using warp threads (32) and weft threads (31). The warp threads (32) and the weft threads (31) are formed by combining multi-ply yarns having different nu
