Dragon flying around paper is according to plants on surface fiber filament type, form, color, texture are different and it is very characteristic.Appearance and tradition
Product is printed compared to more beautiful and original, novel in design, and there is high artistic value.In the world, Japan and South Korea exist at present
It maintains the leading position in the exploitation of dragon flying around paper, domestic mechanism dragon flying around paper exploitation has been achieved with certain achievement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides the preparation sides of a kind of tapa dragon flying around silk and its mechanism dragon flying around paper
Method.
Specific method of the invention is:
(1) prepared by tapa fiber filament: tapa being split and is divided into 1-10mm wide, 5-500mm long, it is dense to be then soaked in quality
Degree is to be warming up to 90-150 DEG C in the sodium hydroxide solution of 2%-20%, keeps the temperature 50-120min, removes pectic substance and hemicellulose
Deng.Then, it is washed with water to neutrality, being added with water to mass concentration is 3%-15%, and sodium hydroxide and the 2%-8% that 1%-8% is added are bis-
Oxygen water (being the mass percent relative to tapa) is warming up to 60-120 DEG C, keeps the temperature 60-120min, washing, removing remnants
Pectic substance, lignin etc. improve tapa whiteness to 85 degree or more, tapa fiber filament are made.
(2) it prepares tapa dragon flying around silk suspension: tapa fiber filament being put into one kind and is discongested in sub-wire equipment, water tune is added
It is 0.1%-1% to mass concentration, starts and discongest equipment, makes fiber filament in fluffy, no bulk slurry group wadding coagulation drop, and slowly stir
Dynamic holding fiber filament is in suspended dispersion always, and under water flow drive, fiber filament direction is consistent with water (flow) direction.It is added
Mass percent of the thickener and lubricant A(of 0.5%-5% relative to tapa), the viscosity of water is improved, and promote fiber filament
Between mutually wadding it is poly-, and equipment agitation is discongested by control, and by the speed of control water flow, so that fiber filament suitably wad a quilt with cotton and gather.It is fine
Dimension silk forms certain fibre bundle after agitation.Then be added 0.1%-1% cationic substance B, the material surface have compared with
Strong cationic charge interacts with anionic charge with filament surface, fibre bundle inner tight is promoted to combine, and
Promote single fiber filament and fibre bundle wadding poly-, forms the fibre bundle of stable structure.The dispersing agent C of 0.5%-5% is added,
The dispersing agent neutral, will not destroy the rock-steady structure of fibre bundle, be also prevented from the fibre bundle wadding group of being polymerized to.With blender
Stirring, flow shear promote fibre bundle at " streamlined " and " shuttle shape " shape, and such as flowing water curve, form is graceful, the fibre
Tieing up tow is " dragon flying around silk ".The length of dragon flying around silk can be adjusted as needed, and range can reach 5mm-100mm.
(3) dragon flying around silk Top wire former: " dragon flying around silk " suspension is diluted to a certain concentration, is flowed, is driven naturally by water
" dragon flying around silk " is laid in long net surface, and by dehydration, " dragon flying around silk " transfer is on the surface of fourdrinier wire." dragon flying around silk " because water flow drives,
Form graceful tracing pattern.
(4) base paper prepare: wood pulp through discongesting, defibrination, certain paper making additive, including filler, retention agent etc. is added, so
Base paper is made in Top wire former afterwards.
(5) composite molding prepares dragon flying around paper: " the dragon flying around silk " of forming is compound with base paper, after certain pressure is compound,
Dragon flying around silk is transferred to base paper surface, and using squeezing, drying, the workshop sections such as roll paper prepare dragon flying around paper.
Furtherly, chemicals A is in the agent of oxidized starch gluing, the agent of polyvinyl alcohol gluing or water-based polyurethane adhesive
It is one or more.

Measure percentage), it is allowed to interact with filament surface anionic charge, promotes fibre bundle inner tight to combine, and promote
Single fiber filament and fibre bundle wadding are poly-, form the fibre bundle of stable structure.The dispersing agent C for adding 0.5%-5% is (opposite
In the mass percent of tapa), while not destroying fibre bundle rock-steady structure, prevent the fibre bundle wadding group of being polymerized to.So
It is stirred afterwards by blender, flow shear promotes fibre bundle at " streamlined " and " shuttle shape " shape, such as flowing water curve, shape
State is graceful, which is " dragon flying around silk ", as depicted in figs. 1 and 2.
(3) dragon flying around silk Top wire former: " dragon flying around silk " suspension is diluted to a certain concentration, is flowed, is driven naturally by water
" dragon flying around silk " is laid in long net surface, and by dehydration, " dragon flying around silk " transfer is on the surface of fourdrinier wire." dragon flying around silk " because water flow drives,
Form graceful tracing pattern.
(4) base paper prepare: wood pulp through discongesting, defibrination, certain paper making additive, including filler, retention agent etc. is added, so
15-300g/m is made in Top wire former afterwards2Quantitative base paper.
(5) composite molding prepares dragon flying around paper: " the dragon flying around silk " of forming is compound with base paper, after certain pressure is compound,
Dragon flying around silk is transferred to base paper surface, and using squeezing, drying, the workshop sections such as roll paper prepare dragon flying around paper.
Furtherly, chemicals A is in the agent of polyvinyl alcohol gluing, the agent of oxidized starch gluing or water-based polyurethane adhesive
It is one or more.
Furtherly, cationic substance B is one or both of cationic polyphosphate, cationic policapram.
Furtherly, chemicals C dispersing agent is glyceryl monostearate, polyacrylamide and its derivative, alkylnaphthalene sulphur
One or more of sour sodium, or cooperate in any proportion.
Furtherly, dragon flying around paper fiber surface " dragon flying around silk " close structure, is evenly distributed.
