Abstract

The invention discloses a pollution-resisting web squeezing paper blanket making method, which is characterized by the following: forming paper-making blanket of weaved bottom web grey cloth through profiling and punching; impregnating the blanket through pollution-resisting agent within fluorine compounds and adhesive after cleaning; precompressing and baking the blanket to generate pollution-resisting web squeezing paper blanket, wherein the pollution-resisting agent formulation is the adhesive of polytef and melamine. The method contains obvious pollution-resisting effect, rational making method and easy operation, which reduces the disposal cost and improves the product added value greatly.

Description

technical field [0001] The invention relates to the finishing technology of industrial textiles in the textile industry, and refers to a manufacturing method of an anti-pollution bottom wire press papermaking felt. Background technique [0002] The papermaking process is a process in which the papermaking clothing is continuously drained. The papermaking felt is used in the press section of the paper machine, mainly through the press roll of the paper machine to exert pressure on the wet paper sheet and the felt to remove a certain amount of moisture in the wet paper sheet. In addition to cellulose fibers and other useful substances that make up paper sheets, pulp also contains resins, lignin and other substances that can adhere to papermaking felts. When the wet paper sheet and felt pass through the nip formed by the press rolls, these substances have a tendency to adhere to the surface of the felt fibers and block the pores of the felt. Once this phenomenon occurs, altho...
