Accompanying drawing explanation
Fig. 1 is the flow chart of the manufacture method of a kind of cheque paper that the embodiment of the present invention provides.
Detailed description of the invention
Refer to Fig. 1, Fig. 1 is the flow chart of the manufacture method of a kind of cheque paper that the embodiment of the present invention provides, and as shown in the figure, the manufacture method of the cheque paper of the present embodiment comprises the following steps:
S101: lithocyte component is dyeed.
The lithocyte of the embodiment of the present invention is a kind of prothenchyma (of wood) with supporting function, and they have thick, usually lignified secondary wall, have common simple pit.Generally all protoplast is lost after ripe.In many plants, lithocyte shows as idioblas in the distribution of lithocyte, i.e. the aspect such as thickness of its shape, size and wall, comparatively easily and peripheral cell distinguish and come.
Wherein, the lithocyte component in the embodiment of the present invention can be the lithocyte component obtained by any way.As a kind of concrete implementation, the lithocyte component of the embodiment of the present invention by filtering out from slurry wherein.Specifically can select containing in the many leaf wood slurry of lithocyte Component comparison, grass tree section slurry wherein or both combined slurries, after fiber is screened out to leaf wood slurry and/or grass tree section slurry, then pass through >=325 object net collection screens except the gleanings after fiber, from gleanings, then filter out lithocyte component wherein.
Wherein, leaf wood slurry can be selected from wherein one or more the combination in poplar, birch, Eucalyptus, beech, principal columns of a hall wood and Acacia, and grass tree section slurry can be selected from wherein one or more the combination in bamboo, reed, reed, giantreed, bagasse, kaoliang stalk, straw, wheat straw, mulberry skin, wingceltis skin and structure skin.
Wherein, as a kind of concrete implementation, dyeing to lithocyte component and specifically can realize in the following manner: lithocyte solution lithocyte component being configured to 1-10%, is the dye liquid mixing and stirring of 0.1-1% by lithocyte solution and concentration, such as stirs 5-20 minute.Stir and terminate to carry out filtering to obtain the lithocyte component after dyeing.
Wherein, as a kind of citing specifically, the kind of dyes of the embodiment of the present invention is one or more the combination in ACID DYES, basic-dyeable fibre, direct dyes and pigment.Dyestuff colour system be redness, yellow, bluish violet, purple and orange in the formed induced color of one or more combinations.
S102: the lithocyte component after dyeing is added in paper making pulp system, carries out paper making and obtain cheque paper.
Wherein, as a kind of concrete implementation, by through hyperchromatic lithocyte to be added in paste system relative to the ratio of slurry oven-dry weight 0.01%-1% (such as 0.02%, 0.04%, 0.06%, 0.1%, 0.5% etc.), wherein preferred proportion is 0.01%-0.1%, such as 0.05%, 0.08%, 0.09% etc., slurry temperature is controlled at 20-60 DEG C, slurry concentration controls at 0.1-10%, subsequently after handsheet paper machine is shaping, again through squeezing, oven dry, shaping cheque paper can be obtained.
Obtained paper can uncoated or process coating.Normally meet light to watch, paper surface has the coloured color dot of slight band of random distribution; Under general backlight irradiates, transparent clearly color dot paper with random distribution can be seen.
The manufacture method of the cheque paper that the above embodiment of the present invention provides, by dyeing to lithocyte component, then saying that the lithocyte component after dyeing is added in paper making pulp system, carrying out paper making and obtain cheque paper.Make use of the transparent lenticular of lithocyte, be colored transparent lenticular after dyed, its structure and optical property are different from general fibre, define difference to a certain degree, thus realize manufacturing paper with pulp of cheque paper with paper fibre optical characteristics.By such mode, only need the lithocyte component of adding dyeing in the paper making pulp system of routine, manufacturing paper with pulp of cheque paper can be realized, be simple and easy to implement.
