Abstract

The invention relates to kitchen paper prepared by regenerating and utilizing Qianjinfang medicine residue resources, and a preparation method thereof, and discloses a method for preparing kitchen paper by regenerating and utilizing Qianjinfang medicine residue resources, wherein the method comprises: ethanol pulping, puffing, extracting of medicinal ingredients from cooking liquid, papermaking, paper modification, and the like. According to the present invention, the kitchen paper is prepared by using the Qianjinfang medicine residue raw material, and the puffing treatment process is additionally set in the preparation process, such that the prepared kitchen paper has high bulkness and high softness, the durability of the fiber is good, and the paper can maintain good water absorption andoil absorption performances in the case of no embossing treatment; the raw paper is subjected to hot air drying after freezing treatment so as to significantly improve the tensile strength of the paper; and the medicinal ingredients are extracted from the pulping cooking liquid, and are applied to the fiber, such that the finally obtained fiber product has good antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of regeneration and utilization of medicinal dregs resources, and in particular relates to a kitchen paper prepared by recycling medicinal residue resources of Qianjin Fang and a method thereof. Background technique [0002] Kitchen paper belongs to a new type of household paper. Because of its hygiene, convenience, and environmental protection, it has gradually been widely used and is more and more favored by consumers. Kitchen paper can not only be used to remove water , filter oil, absorb excess oil from fried food, and can also play a role in wiping and cleaning around the kitchen. With the improvement of people's consumption level and quality of life, the development trend of kitchen paper is increasing day by day, and people's requirements for kitchen paper are getting higher and higher. [0003] Existing kitchen paper is usually prepared by laminating a certain number of sheets of embossed sanitary t...
