Problems solved by technology

[0004] Some manufacturers often add a large amount of fluorescent agent in order to pursue the whiteness of the paper, which will not only cause pollution, but also cause harm to the human body. After the fluorescent agent is absorbed by the human body, it will combine with the protein in the human body, making it difficult to be decomposed. It can only be excreted through the en

Embodiment 1

[0027] S1: After 30 days of stockpiling, the purchased bamboo chips are first screened out of long pieces and bamboo chips, then washed to remove impurities such as silt and bamboo chips, and finally dehydrated and sent to the factory by a belt conveyor Storage of bamboo chips;

[0028] S2: Use a belt conveyor to put the raw materials of bamboo slices in the silo into the pot, and use the alkaline method for cooking, add cooking liquid to the bamboo slices, the liquid ratio is 1:3, and heat up the cooking liquid to 140-170°C in circulation. Boost the pressure to 0.4Mpa and keep warm for 20 minutes. The whole cooking time is 240 minutes. The cooking liquid is a sodium hydroxide solution, wherein the amount of sodium hydroxide is 15% of the absolute dry raw material amount. The cooking liquid does not contain sodium sulfide, nor use of cooking aids containing sulfur;

[0029] S3: Sieve out the bamboo knots and thick fiber bundles in the slurry by means of closed screening, wash...

Embodiment 2

[0034] S1: After 100 days of stockpiling, the purchased bamboo chips are first screened out of long pieces and bamboo chips through a bamboo chip sieve, then washed to remove impurities such as sediment and bamboo chips, and finally dehydrated and sent to the factory by a belt conveyor Storage of bamboo chips;

[0035] S2: Use a belt conveyor to put the raw materials of bamboo slices in the silo into the pot, use the alkaline method for cooking, add cooking liquid to the bamboo slices, the liquid ratio is 1:6, and heat up the cooking liquid to 140-170°C in circulation. Boost the pressure to 0.7Mpa and keep warm for 60 minutes, and the whole cooking time is 400 minutes. The cooking liquid is a sodium hydroxide solution, wherein the amount of sodium hydroxide is 30% of the absolute dry raw material amount, and the cooking liquid does not contain sodium sulfide, nor use of cooking aids containing sulfur;

Abstract

The invention discloses highly bacteriostatic bamboo fiber toilet paper and a preparation method. Natural color bamboo pulp is prepared by the steps of material preparation, stewing, screening, washing and the like of the highly bacteriostatic bamboo fiber toilet paper, the pulp is made into base paper by the processes of filter press concentration, high concentration grinding, low concentration grinding, low concentration desanding and the like, and then is post-processed, cut and packaged into finished products. According to the highly bacteriostatic bamboo fiber toilet paper, because a sulfur free stewing technology is adopted, an oxygen removal link commonly used in the industry is avoided, the bleaching treatment containing chlorine is not subjected, the production process is environmental friendly, the nature of the bamboo raw materials is retained to the greatest extent, the light bamboo fragrance is achieved, and bamboo quinine contained in the pulp also has the natural bacteriostatic effect.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a high antibacterial bamboo fiber paper towel and a preparation method thereof. Background technique [0002] The mainstream household paper in my country's market is the paper bleached by bleaching agent. In order to make the white paper more beautiful, some special additives, such as talcum powder and blue and purple dyes, are generally added to the paper pulp. Merchants will also take the risk of adding a large amount of fluorescent whitening agent in violation of regulations to improve the brightness and aesthetics of the paper. [0003] Many consumers choose white tissue paper because they think it is hygienic and clean. In fact, this is a misunderstanding. During the pulp bleaching process, carcinogens such as dioxins and adsorbable organic halides will be produced. Dioxins are a class of persistent organochlorine compounds. There are as many as 30 kinds of ...
