| description | The invention discloses paper made of straw and a manufacturing method, and relates to the technical field of papermaking, and the manufacturing method comprises the following steps: S1, carrying out primary treatment on corn straw to soften the corn straw, putting the softened straw into a double-screw thread rolling machine to carry out extrusion and filament separation, putting the filament-separated straw into a 90 DEG C reaction bin to carry out bleaching treatment, s2, the treated straw is poured into the double-screw thread rolling machine again to be subjected to extrusion and thread separation operation again, extruded materials are poured into a pulping machine to be ground, coarse pulp is obtained, black water generated in the grinding process is subjected to an activated sludge method, and the removal rate of suspended matter is increased through chemical precipitation; the harm of sewage is reduced. The straw is extruded and divided, so that a fiber primary wall (p layer) and a fiber secondary wa |
