Description
Technical field
The present invention relates to thermal dye sublimation transfer printing technical field, more particularly, to one kind is dry type thermal dye sublimation transfer printing number paper.
Background technology
Thermal-printing Technology refers to for the contents such as word, figure to use hot print ink printed in common paper or high accuracy
On printing paper, then it is heated to 180～230 DEG C within a few minutes through corresponding thermal transfer equipment, the image color on paper is forced
Very it is transferred to a kind of special process on unlike material.Transfer printing digital paper is the carrier of pattern and ink, being heated to 180～
230 DEG C of transfers are printed in different material medium, and basic guarantee dye molecule is transferred completely on dielectric material.
Number of patent application is 99810480.9 transfer paper for ink jet printing, discloses a kind of transfer paper, this transfer
Paper has sealing coat or barrier layer in one side to be printed, and sealing coat or barrier layer are coated to be printed by coating way
One side on, obtain after coating porosity (or referred to as breathability) be up to 100 ml/min coating.This transfer paper leads to
Cross single layer coating only one index of control porosity, therefore have the shortcomings that ink capacity is little, slow drying speed and the rate of transform are low,
And these three indexs are to ensure three indispensable elements of thermal dye sublimation transfer printing paper product matter at present.Number of patent application is
201310320165.2 composite membrane quick-dry type thermal dye sublimation transfer printing number paper, this digital paper includes substrate paper, hydrophobic layer, ink absorbing layer
And surface layer, wherein hydrophobic layer can prevent dye molecule invade base stock fiber in, improve transferring rate, ink absorbing layer pass through water absorption
Material significantly improves rate of drying, has certain progress.
But digital printing and making quickly grows within this several years, manufactures efficiency to improve, printer is from single spraying head, double spray
Head is notable to the technological progress of many shower nozzles, and printer digital printing manufacturing speed is also promoted to 100 by original 15～30 ms/h～
2000 ms/h, and the making of pattern also becomes increasingly complex, the rate of drying of the digital transfer paper that current technology produces is not
The demand of printing speed can be met.
Content of the invention
The present invention is directed to the shortcoming that rate of drying present in prior art can not meet printing and making speed requirement, provides
A kind of digital paper of i.e. dry type thermal dye sublimation transfer printing that can achieve rapidly dryings, quick blotting, the high rate of transform.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals:
I.e. dry type thermal dye sublimation transfer printing number paper, by the four layer function structure compositions with the quick pervious function that absorbs water, by under
Supreme include successively substrate paper, water suction pervious bed, porous layer, surface channel layer, this four-layer structure achieves quickly inhales from surface
Ink, dyestuff are separated from water the purpose being rapidly dried with moisture through paper fiber.

Wherein, resin complexes be vinyl alcohol-vinyl acetate copolymer, ethylene-vinyl alcohol-acetate ethylene copolymer,
Two or more combination any in polyvinyl acetate, sodium carboxymethyl cellulose, cellulose.
General surface resin layer has certain hydrophilic, but absorbs or slow with contacts ink, and the present invention adopts
Porous silica can be with the porosity of effective control surface channel layer, and the silicon dioxide of different proportion and resin complexes
Surface channel layer space can effectively be adjusted, thus greatly improving the infiltration rate to ink for the surface channel layer.
Under room temperature print when surface channel layer in porous silica silicon compound have very strong water permeable ability pass to many
Aperture layer；Intermolecular hydrogen bonding in high temperature transfer condition undersurface layer reduces, using the teaching of the invention it is possible to provide bigger space, and dye molecule is from turning
Quickly fully distil in printing code paper and coating material, transferring effect is preferable.Surface channel layer has the advantage that ink absorption is fast
Speed, blotting effect are preferable, transfer efficiency is high, keep picture and text bright in luster, and can make porous layer efficient absorption dye molecule,
Water suction pervious bed quickly transmits hydrone.
Preferably, the quality of every square metre of substrate paper upper surface channel layer is 1.5～3.0g.Every square metre of base material
When the quality of paper upper surface channel layer is 1.5～3.0g, it is printed with very strong water permeable ability under room temperature and passes to porous layer；In height
Warm transfer condition lower surface channel layer intermolecular hydrogen bonding reduces, using the teaching of the invention it is possible to provide bigger space, dye molecule is from transfer printing digital paper
Quickly fully distil in coating material, transferring effect is preferable.The quality of every square metre of substrate paper upper surface channel layer is less than
During 1.5g, dark images print and situation that ink do not do occur, wrapup procedure easily dim pattern, directly affect transfer effect
Really produce substandard products problem；When the quality of every square metre of substrate paper upper surface channel layer is more than 3.0g, surface layer is too thick, can shadow
Ring the distillation of dye molecule, also result in transferring effect and be deteriorated, surface channel layer is too thick also directly to increase production cost.
Preferably, porous layer is cellulose or sodium carboxymethyl cellulose or starch is led to cation-modified polyacrylamide
Cross the interpenetrating network resin that diisocyanate is cross-linked to form.
Preferably, porous layer is polyacrylamide or cellulose or sodium carboxymethyl cellulose is led to cationic modified starch
Cross the interpenetrating network resin that diisocyanate is cross-linked to form.
Wherein, calculate according to mass percent, cellulose or sodium carboxymethyl cellulose or starch are 62%～79%, sun from
Sub- modified polyacrylamide is 18%～30%, and diisocyanate is 3%～8%；Or polyacrylamide or cellulose or carboxylic
Sodium carboxymethylcellulose pyce is 62%～79%, and cationic modified starch is 18%～30%, and diisocyanate is 3%～8%.Two is different

Acrylamide copolymer, tertiary amine salt is dimethylamino propyl acrylamide hydrochlorate-acrylamide copolymer, and aliphatic two is different
Cyanate is hexamethylene diisocyanate (hdi) or isophorone diisocyanate (ipdi) or hydrogenation phenylmethane two isocyanide
Acid esters (h12mdi).There is space between cellulose, gap structure can increase blotting amount, shorten transfer time, improve and produce effect
Rate.
In prior art, after the ink absorbing layer in transfer printing digital paper absorbs dyestuff, interpenetrating network resin can rapid expanding " pocket
Live " dyestuff, thus reaching the effect increasing blotting amount, the hydrone in ink and dye molecule all catch, due to rate of drying
Related to interpenetrating network resin expansion, thus the transmitance of wherein hydrone is but very low, therefore quick-dry type thermal dye sublimation transfer printing is digital
Paper can only meet being dried of 15～50 ms/h of printer operating speed and require it is impossible to meet existing printer operating speed 100
～2000 ms/h of demand.The present invention passes through to control the resin composition of interpenetrating network resin to improve water penetration with network density
