Abstract
The present invention relates to a method for combining living paper by utilizing collagen fiber and vegetable fiber. Firstly, lime leftovers are washed by water, degreased and added into a masher to be mashed, and after magnesium oxide is added, water is added for dilution and hydrolysis, and collagen fiber pulp is obtained. Secondly, hexadecyl trimethyl ammonium bromide and phosphate ester are mixed to react to generate softening agents. Thirdly, bleached needle leaf (broad leaf) wood pulp and wheat straw pulp are conditioned to make the mass concentration of the pulp reaches 1% to 4%, the bleached needle leaf (broad leaf) wood pulp, the wheat straw pulp and the collagen fiber pulp are mixed, and the softening agents are added into a pulping tank. Finally, after being mixed, the prepared pulp is delivered to a paper machine net, and wet paper is squeezed, dried, coiled and processed into finished products. Collagen fiber extracted from lime leftovers in solid waste of tanning is used as raw material for making paper, so that raw wood pulp can be saved, the dosage of paper additives is reduced, the production processes are simplified, and the pollution of paper making is reduced. Due to the content of the collagen fiber, the living paper has the advantages of favorable affinity with human bodies, high intensity and favorable flexibility.
Description
Technical field
The present invention relates to a kind of method of compound paper for daily use, particularly a kind of method of utilizing collagenous fibres and the compound paper for daily use of string.
Background technology
Utilizing compound this one side of sheet of copying of collagenous fibres and string, only there is Sichuan University to pay the beautiful red correlative study of once doing at present, and the patent of applying for " preparation method of collagen protein face paper ", but she extracts collagen to do raw material in the chrome leather scrap that directly adopts in the tanning waste, need take off chromium, its complex manufacturing, the cost height.
Summary of the invention
The object of the present invention is to provide a kind of chromium that need not to take off, and can reduce production process, the cost-effective method of utilizing collagenous fibres and the compound paper for daily use of string.
For achieving the above object, the method that the present invention adopts is: at first slurrying, be sent to paper machine net after the slurry mixing with system then, l Water Paper is through squeezing, dry, batch, get product after the processing, be characterized in, said slurrying comprises: at first the graywall leftover bits and pieces in the solid leather wastes is washed, conventional degreasing agent degreasing with graywall weight 1%-5%, be cut into 2mm * 2mm to 5mm * 5mm fritter, add in the bruisher, smash to pieces 0.5-2 minute * 2-4 time, dilute with quality multiple 50-100 water doubly behind the magnesia of adding graywall weight 5%-10%, at 45 ℃ of-60 ℃ of following hydrolysis 1-3 hours, be dispersed in the hydrolyzate with refiner, promptly get collagen fiber pulp; Softex kw and the mass concentration that with mass concentration is 20%-40% is that the phosphate of 20%-40% mixes by mass ratio at 1: 1, normal-temperature reaction 30-60 minute, makes softener; To bleach pin wood and/or wealthy wooden leaf wood pulp, Straw Pulp then respectively through the hydrabrusher pulping and in stock tank, size mixing respectively and make the mass concentration of slurries reach 1%-4%, and behind paste mill grinding, enter respectively and kowtow the back stock tank; Bleaching pin wood and/or wealthy wooden leaf wood pulp with mass percent 15%-30%, the Straw Pulp of 50%-78% and the collagen fiber pulp of 5%-20% mix to be placed in the same stock proportioner joins slurry, join behind the slurry through joining stock tank and machine chest, adding mass percent in machine chest is the softener of 0.5%-1.0%.
Because the present invention can save former wood pulp consumption with the collagenous fibres that the graywall leftover bits and pieces in the solid leather wastes extracts as the paper grade (stock) raw material, reduce the use of paper making additive, and simplified production process, reduce paper-making pollution.Owing to contain collagenous fibres, this type of paper for daily use and human body affinity are good, the intensity height, and flexibility is good.
