Abstract

The invention relates to high-air-permeability mixed pulp, which contains high-air-permeability straw pulp. The mixed pulp contains 10-100 percent of high-air-permeability straw pulp and 0-90 percent of other pulp by weight percent. Preferably, the weight percent of the high-air-permeability straw pulp is 30-97 percent and the weight percent of other pulp is 3-70 percent. More preferably, the weight percent of the high-air-permeability straw pulp is 51-95 percent and the weight percent of other pulp is 5-49 percent. The most preferably, the weight percent of the high-air-permeability straw pulp is 71-93 percent and the weight percent of other pulp is 7-29 percent. The other pulp is one or more of wood pulp, bamboo pulp, cotton pulp and secondary fiber. Preferably, the wood pulp and the bamboo pulp are selected. The mixed pulp has the advantages that the drainage capacity is good, the high-speed paper machine can be used during papermaking and the production efficiency is further improved.
