Among the lost handmade papers, the developed paper is considered to be one of the best Ming and Qing ancient book printing imperial papers, the paper quality of the developed paper is white, soft, smooth, fine, free from curtain lines, thin and tough, and has very high historical status and cultural value. Therefore, the manufacture of the high-quality handmade paper is an important problem to be solved urgently at present, has a promoting effect on the technical reconstruction of ancient paper, and also has an important significance on the development of related subjects such as the arrangement, protection, utilization and the like of ancient books.
Patent CN105544282B discloses a paper making process using paper mulberry bark as raw material, which comprises, first screening paper mulberry bark, soaking, boiling in a paper steamer, rolling, adding quicklime for a period of time, then boiling the obtained paper mulberry bark in a paper steamer at high temperature, washing the obtained paper mulberry bark to remove lime and impurities, rubbing and peeling, cutting the peeled raw material into thin pieces with a steel knife, mashing in a stone groove to obtain paper pulp, finally pouring the mashed paper pulp into a paper groove filled with water, stirring sufficiently to make the paper pulp form uniform suspended floccule in water, then making paper and squeezing, sweeping, drying and uncovering wet paper with water, however, it is not directed to the making of paper, does not have the advantages of traditional manual paper making, and more importantly, in the bark fiber as the paper making raw material, the width of the wild goose skin fiber is smaller, the length-diameter ratio is larger, and the wild goose skin fiber is more flexible; in the cooking step, the time is shorter, the temperature is lower, the bleaching step which is originally required to be independently operated is completed in one step through the combined action of lime and hydrogen peroxide, and the production period is greatly shortened.
Disclosure of Invention
The invention aims to solve the problems and provide a method for making the opened paper based on wild goose bark fibers, the method takes the wild goose bark fibers as raw materials, the opened paper is made by the processes of solarization, fermentation, alkali cooking, beating, medicine adding and the like of the wild goose bark fibers, the method has the characteristics of high efficiency and short time, the fibers can be simultaneously cooked and bleached within 3 hours at the temperature of not higher than 100 ℃, the production period is shortened, and the method has the potential of being suitable for large-scale production.
The purpose of the invention is realized by the following technical scheme:
a preparation method of opened paper based on wild goose bark fiber is characterized in that wild goose bark is used as a raw material and is prepared by the procedures of sun drying, soaking fermentation, retting, coarse smashing, alkali boiling, fine grinding, size mixing, paper fishing and paper drying.
A preparation method of a starting paper based on wild goose bark fiber comprises the following steps:
(1) preparing materials: drying wild goose barks in the open air;
(2) soaking materials: soaking the obtained sun-dried goose bark in water;
(3) cutting: cutting the soaked goose barks;
(4) retting the pulp: putting the wild goose barks into a retting pool, and pouring plant ash;
(5) coarse tamping: pounding the goose barks subjected to the retting treatment directly until the fibers are loose and separated;
(6) cleaning: washing the mashed pulp;
(7) and (3) cooking: putting the smashed loose fibers on a steamer for steaming, then adding lime and hydrogen peroxide, and steaming again to obtain paper material;
(8) fine grinding: finely mashing the paper material in batches to form fine pulp;
(9) size mixing: pouring the prepared pulp fiber into a paper tank filled with clear water, adding the cactus juice, and uniformly stirring by using a wood stick. The cactus juice is a natural high-quality adhesive, has high-efficiency adhesion effect among fibers, and improves the strength of paper.
(10) Fishing out paper: firstly, flatly placing a bamboo curtain on a paper fishing frame, extending into a paper groove, and tucking up from the water from the outside to the inside to obtain wet paper sheets;
(11) drying the paper: drying the wet paper sheets together with the paper frame in the sun;
(12) uncovering paper: the dried paper sheet is fed and finished for use.
Preferably, the wild goose barks are sun-dried in the open air for 1-2 months in the step (1).
Preferably, the sun-dried goose bark is soaked in water for 1 month in the step (2).
Preferably, the step (3) cuts the above-mentioned impregnated goose barks into sheets having a length of 20 cm.
Preferably, the loose fibers smashed in the step (7) are put on a steamer to be steamed for 2-4 hours at the temperature of 80-100 ℃ for the first time, and are steamed for 1-3 hours again at the temperature of 60-80 ℃. The first cooking is to remove air in the capillary pores of the fiber raw material through the steam permeation, the cooking effect is poor at a low temperature when the temperature is lower than 80 ℃, the effect on the pores of the inner layer of the fiber is not good, and when the temperature is higher than 100 ℃, the effect can be further improved by continuously increasing the temperature, but the energy consumption is wasted. The exhaust function of the first cooking also lays a foundation for the second cooking. Meanwhile, the temperature of the use environment and the action efficiency of the hydrogen peroxide are both considered, and the control at 100 ℃ is more suitable. When the temperature is lower than 60 ℃, the pulp cooking effect is poor, the pulp is still stiff and is not easy to form pulp, and when the temperature is higher than 80 ℃, the decomposition of hydrogen peroxide is intensified, so that the effect of bleaching while cooking can not be achieved.
Preferably, the lime and the hydrogen peroxide in the step (7) are added in an amount of 10 wt% of the mass of the slurry. Lime has the functions of steaming and boiling the medicament and adjusting the hydrogen peroxide environment, and compared with the dosage of 20-50 wt% in the traditional hand-made paper production, the dosage of the medicament is relatively less.
Preferably, when the paper is fished in the step (10), the bamboo curtain is firstly flatly placed on the paper fishing frame, extends into the paper groove, is bellied from the outside to the inside, transversely and violently shakes for 3-5 times, and stays for 5 seconds. The operation makes the fiber have orientation distribution in both longitudinal and transverse directions, and eliminates the anisotropy of the fiber.
Preferably, in the step (4), the plant ash accounts for 20% of the mass of the pulp.
Preferably, in step (9), the cactus juice is used in an amount of 5% by mass of the slurry.
Compared with the prior art, the invention has the following beneficial effects:
the opening paper manufactured by the method has the advantages of the traditional hand-made paper, is suitable for large-scale production, and has good artistic value and social and economic benefits. In the aspect of process, the wild goose bark selected by the invention is a good papermaking raw material with developed bast fiber and larger long diameter. The effect of the subsequent steps is improved by adopting a mode of cutting firstly, the unevenness of the cooking effect is increased by overlong raw materials, and the fiber length is reduced violently by overlong raw materials after cooking, which can cause poor paper-making performance; the optimized fiber length is adopted, a slight retting treatment is adopted, and a rough pulping step is adopted after retting, so that enough alkali can be ensured to act on the fiber through infiltration; lime and hydrogen peroxide are adopted for treatment in the cooking step, the aims of cooking and bleaching are achieved in one step, in the conventional manufacturing process, unbleached pulp is obtained after cooking, a bleaching section is required to be equipped if the whiteness is improved, more treatment processes cause more damage to fibers, so that the alkaline conditions and agents for cooking and bleaching are considered, the lime and the hydrogen peroxide are selected for treatment together, and further, the cooking temperature is controlled below 100 ℃ in cooperation with the use temperature of the hydrogen peroxide, so that the aim of one-step pulp-forming bleaching is achieved; the whole process is controllable, the severe cooking process is replaced by a plurality of relieving steps, the advantages of the traditional manual papermaking are well utilized, the production period is favorably shortened, and the potential of being suitable for large-scale production is realized.
