Embodiment 1

[0027] S1 Material preparation: After 30 days of stockpiling, the purchased bamboo chips are first screened out of long pieces and bamboo chips through a bamboo chip sieve, and then washed to remove impurities such as sediment and bamboo chips, and finally dehydrated. Store in the bamboo chip warehouse.

[0028] S2 cooking: Alkaline cooking is adopted, in which the amount of sodium hydroxide is 30% of the absolute dry raw material, the cooking liquid does not contain sodium sulfide, and does not use sulfur-containing cooking aids, the liquid ratio is 1:6, and it is conveyed by a belt The machine puts the raw materials of bamboo slices in the silo into the pot, and then adds the cooking liquid. The cooking liquid is heated up to 140-170°C in circulation, and the pressure is increased to 0.7Mpa for 20 minutes. The whole cooking time is 400 minutes.

Abstract

The invention discloses nature bamboo fiber kitchen towels with high antibacterial property and a preparation method. The preparation method comprises the following steps: S1, washing bamboo sheets, removing impurities of the bamboo sheets and performing dehydration for subsequent use; S2, steaming and cooking the bamboo sheets by adopting an alkali method; S3, screening out bamboo joints and coarse fiber bundles of pulps which are obtained after steaming and cooking, and processing the bamboo joints and the coarse fiber bundles by adopting a hot water counter-current washing method; S4, concentrating the obtained nature bamboo pulp fibers through a press filter, and performing high-concentration pulp grinding and low-concentration pulp grinding to obtain paper pulps; S5, performing dilution, sand removal, molding, dehydration, drying, wrinkling and rolling on the paper pulps to obtain raw paper; and S6, slicing and packaging the raw paper. The nature bamboo fiber kitchen towels with the high antibacterial property disclosed by the invention adopts a sulfur-free steaming and cooking process, an oxygen delignification step which is adopted generally in the industries is eliminated,and chloride-containing bleaching treatment is avoided, and therefore, a production process is green and environmentally friendly, the properties of bamboo raw materials are kept to the maximum extent, the nature bamboo fiber kitchen towels have a faint fragrance of bamboos, and bamboo quinone contained in the pulp has a more natural antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high antibacterial natural color bamboo fiber kitchen paper and a preparation method thereof. Background technique [0002] The mainstream of household paper in my country's market is paper bleached with bleaching agent. In order to improve the whiteness of toilet paper and increase the appearance of paper, paper mills generally add some special additives to the pulp of papermaking. In order to pursue high whiteness of paper, some manufacturers take the risk of using a large amount of fluorescent whitening agent in violation of regulations to improve the brightness and aesthetics of paper, which will not only cause environmental pollution, but also cause human cells to mutate and accumulate toxicity. Potential carcinogenic factors, after the fluorescent agent is absorbed by the human body, it will cause harm to the human body. [0003] Many consumers have a mis...
