Abstract
The invention relates to a method for improving the wet tensile strength of a tobacco sheet of a paper-making process. The method comprises the following steps of: weighing hydroxyethyl cellulose with an average molecular weight of 150,000-200,000 and a degree of substitution of 0.8-1.6, and adding clear water to prepare a solution with a mass concentration of 1 percent; weighing chitosan with an average molecular weight of 300,000-500,000 and a deacetyiation degree of 85-95 percent, dissolving by using an acetic acid solution with a mass concentration of 1 percent, and adding clear water to prepare a chitosan solution with a mass concentration of 1 percent; and adding the prepared hydroxyethyl cellulose solution and the chitosan solution to the tobacco sheet, wherein the addition quantities of the hydroxyethyl cellulose and the chitosan are respectively 0.2-0.6 percent and 0.05-0.2 percent of the absolute dry quantity of a tobacco raw material during tobacco sheet making. According to the method of the invention, the wet tensile strength of the tobacco sheet is improved, the continuity of production is effectively, and particularly, the production continuity during making tobacco sheets with a lower fix quantify is guaranteed.
Description
Technical field
The present invention relates to a kind of method that improves the tobacco sheets by paper making method wet tensile (strength), belong to the tobacco sheets by paper making method production technical field.
Background technology
Tobacco sheets by paper making method is to utilize offal discarded in the cigarette process, offal, smoked sheet etc. and some strings as raw material, and the thin slice of processing near tobacco leaf through paper-making process is used further to production of cigarettes.Single angle from papermaking; Offal, offal and smoked sheet are not a kind of good paper making raw materials; Because offal, tobacco stalk fibre length are lacked, fiber fines is many, heteroproteose cell content is high; Can bring a series of puzzlement to manufacturing paper with pulp of back reconstituted tobacoo, especially the wet tensile (strength) influence to the tobacco substrate is very big.
The wet tensile (strength) of tobacco substrate is the index of the special control of needs in the tobacco sheets by paper making method production process; Because the too small meeting of the wet tensile (strength) of tobacco substrate causes reconstituted tobacoo the broken end phenomenon in coating process, to occur, thereby have a strong impact on the continuity of production.When especially producing quantitatively lower reconstituted tobacoo, the wet tensile (strength) of tobacco substrate is a key factor of restriction ordinary production.
In early days, people use the concentrated sulfuric acid to make the fiber gel, or add artificial silk mucus such as cellulose acetate, nitrocellulose, hydroxyethylcellulose etc., re-use acid, basic salt is deposited on the fiber it increases the wet tensile (strength) again of page to improve water repelling property.The present increase page best bet of wet tensile (strength) again is to add some thermosetting wet strengthening resins, like Lauxite, daiamid epoxy resin, melamine resin, polymine etc.But because the particularity of tobacco business, make that adjuvant used selection is restricted in the tobacco sheets by paper making method production, must reach natural, nontoxic, have performances such as good retention aid and filtering aid and enhancing simultaneously.Because thermosetting resin all contains a large amount of nitrogen elements, the combustion potential of nitrogen element must produce toxic gas, so thermosetting resin can not be applied in the reconstituted tobacoo.
Hydroxyethylcellulose is a kind of nontoxic wet strength agent; The strong mechanism of its humidification is to be deposited between the fiber through high molecular polymer to constitute cancellated amorphous interweaving with fiber; Limited interfibrous activity; Also limit the performance such as expansion and page dilatation of fiber accordingly, thereby increased the wet strength of paper.Shitosan also is in the reconstituted tobacoo industry, to use wider auxiliary agent at present; It also has the effect of certain increase page wet strength; Its mechanism of action mainly is: shitosan is a linear macromolecule, and relative molecular mass is bigger, has good film forming ability; Have enough bonding strengths also can between fiber, build bridge to fiber, positive center on its strand and hydroxyl, part amino have formed numerous intermolecular hydrogen bondings with the hydroxyl in the nonionic zone of fiber surface.In addition, the basic group in the chitosan molecule can be fully near fiber surface, not only can form ionic bonding with the carboxyl of fiber surface, also can form a small amount of covalent bond with some aldehyde radicals of existing in the fiber, thereby improve the wet tensile (strength) of tobacco substrate.
Use hydroxyethylcellulose also bad to the reinforced effects of page wet strength separately, its reason is that the hydroxyethylcellulose surface is electronegative, is difficult to be deposited in same electronegative fiber surface, and the aluminum sulfate that generally all need add positively charged is done precipitating reagent.Use its reinforced effects of shitosan also not good separately; Its reason is shitosan addition strong DeGrain of humidification when low; When addition is higher,, can have a strong impact on the evenness of manufacturing paper with pulp of reconstituted tobacoo because the strong wadding of shitosan gathers effect; The shitosan expensive taking cost into account also should not be added too much simultaneously.Therefore use hydroxyethylcellulose and shitosan to act synergistically and strengthen the wet strength of tobacco substrate; Because the shitosan electropositive is very strong; Shitosan can be when increasing the reconstituted tobacoo wet strength as the precipitating reagent of hydroxyethylcellulose; Improve the retention of hydroxyethylcellulose greatly, thereby effectively improve the wet strength of tobacco substrate.
Summary of the invention
The invention provides a kind of method that improves the reconstituted tobacoo wet tensile (strength); Hydroxyethylcellulose and shitosan are applied to the production of reconstituted tobacoo; Utilize synergy hydroxyethylcellulose and shitosan to be deposited between the fiber and constitute cancellated amorphous interweaving with fiber; Limit interfibrous activity, thereby increase the wet tensile (strength) of tobacco substrate.
