Case gloss is constant low and deep.Illustrate technical solution of the present invention below by way of specific embodiment.
Embodiment 1
As shown in the flowchart of fig.1, the method being embossed again after gold stamping stamp of the present invention makes triangular fibre first
Fabric then successively carries out gold stamping stamp and embossing to it, the specific steps are as follows:
(1) it makes triangular fibre fabric: selecting cross section to be spun into fabric for the terylene triangular fibre of triangle and obtain
Triangular fibre fabric.
(2) gold stamping stamp: open width is put into roller together after being respectively bonded above-mentioned triangular fibre fabric with gold stamping mould paper
Formula gilding press, and moved with the speed of 20m/min.
Wherein the gold stamping mould paper include PE film ground layer and the breakcoating being fixed on PE film ground layer and according to
The secondary coat of metal and function of glue coating being layered in breakcoating, the function of glue coating are bonded with dacron surface.And it is described
The silicone resin layer that breakcoating selects heated rear viscosity to be lower, the strong temperature-sensitive of viscosity change after the function of glue coating selection is heated
Adhesive layer, such as polyurethane, polystyrene, polyacrylate.
The operating parameter for adjusting gilding press applies 4 tons of pressure and 135 DEG C of temperature to triangular fibre fabric and gold stamping mould paper
Degree, makes the coat of metal on gold stamping mould paper adhere to triangular fibre fabric surface by function of glue coating and forms gold stamping pattern.
(3) gold stamping mould paper substrate is removed: by triangular fibre fabric together with gold stamping mould paper after to gold stamping stamp
Clot is put in oven, is cooled down at 50 DEG C for 24 hours afterwards by the PE film ground layer of gold stamping mould paper and breakcoating from triangular fibre
Fabric surface strips down.
(4) it is embossed: will be by step (3) treated triangular fibre fabric open width under the movement speed of 20m/min
It is put into roller embossing machine, makes to carve figuratum roller (i.e. mold) in the case where pressure is 4 tons, temperature is 195 DEG C in fabric
Surface applies pressure and heat, and dacron surface is made to form concave-convex decorative pattern, i.e. embossed pattern.By triangle fibre after embossing
Tie up fabric clot.
As a comparison, while cross section being selected to be spun into fabric for pentagon, triangular hollow type and circular fiber, then
The fabric is handled according to above-mentioned steps (2)~(4) technique respectively.
Felt carrying out pattern of the gold stamping stamp again after embossed technology to fabric made of above-mentioned four kinds different fibers
Official's evaluation, as a result as follows:
The result shows that being respectively triangle by cross section, the terylene of three kinds of pentagon, triangular hollow type fibers production is knitted
Object can individually obtain the full gold stamping pattern of metallic luster after the processing of gold stamping embossed technology, and cross section is circular
Fiber surface metallic luster is low and deep.But be further continued for after being embossed process, only triangular fibre fabric can retain
The full metallic luster of gold stamping pattern, although and cross section is that the dacron that pentagonal fiber makes can be made clearly
Embossed pattern, but the metallic luster of its gold stamping pattern has become low and deep;Cross section is that the fiber of triangular hollow type makes
Dacron embossed pattern edge blurry is not only then being pressed after embossed technology is handled, but also be the gold stamping pattern of script
Change colour low and deep unglazed.
Then three kinds are carried out home washings 15 times by the dacron that gold stamping stamp is embossed again again, it can be seen that crosscutting
The dacron that face makes for the fiber of triangle still remains the full gold stamping pattern of gloss and clearly embossed pattern,
Do not change before opposite washing;Cross section is the dacron gold stamping pattern after washing and pressure of pentagonal fiber production
Also there is no variations for floral pattern;And cross section be triangular hollow type fiber make dacron after washing its
Embossed pattern becomes seriously fuzzy.
For the fabric of different fibers production by same process processing, final pattern effect is different, mainly due to
The distribution of the coat of metal of different fiber surfaces and its different to the effect of light.
During gold stamping stamp, the function of glue coating on gold stamping mould paper is become strong by thermal viscosity, is made securely with fiber surface
With so that the coat of metal is uniformly adhered to dacron surface fullly.Breakcoating is lower by thermal viscosity simultaneously, so that metal
Coating is separated.For triangular fibre, pentagon and triangular hollow fiber type, the coat of metal is sticked to fiber surface
In the plane distribution of continuous and derivable, continuous mirror-reflection is formed to light, shows full metallic luster;And for circle
For fiber, the coat of metal is sticked to fiber surface distribution in curved surface, carries out diffusing reflection to light, metallic luster is low and deep.
Then in subsequent embossing process, the fiber of dacron is pressurized and is heated, and is carving figuratum roller
Under effect, the region of pattern contacts forms concave-convex decorative pattern in dacron surface and roller.For triangular fibre, though
It is melted after right function of glue coating is heated, mobility becomes larger, but due to triangular fibre stable structure, will not occur when being pressurized heated
Deformation, therefore function of glue coating will not be squeezed, the distribution on triangular fibre surface will not change, then metal-plated
Distribution of the layer on triangular fibre surface does not also change, so as to keep the full metallic luster of original gold stamping pattern.
For pentagon fiber, after gold stamping stamp, its two angle or three for being in surface in embossing process
A angle is bent downwardly after compression, causes its distribution to become uneven so that function of glue coating be made to be extruded, the coat of metal is caused to exist
The partial region of pentagon fiber surface is not distributed, but may be thickly stacked together in partial region, cannot the company of being formed
Continue smooth metal coating surface, and compared to changing before embossing to the reflection angle of light, light can not be connected
Continuous mirror-reflection, along with diffusing reflection, therefore gold stamping pattern will become low and deep.Similarly, for triangular hollow fiber type
For, surface is recessed inwardly by severe crush, structure, so that the function of glue coating on its surface be made to be extruded, leads to metal-plated
The hollow type fiber surface of layer after deformation cannot form the plane of continuous and derivable, carry out before no image of Buddha embossing to light continuous
Mirror-reflection, therefore gold stamping pattern will become low and deep.For circular fiber, shape does not occur after being under pressure in embossing process
Become, the coat of metal is sticked to fiber surface still distribution in curved surface, keeps carrying out diffusing reflection, the low and deep phenomenon of metallic luster to light
Also do not improve.
Embodiment 2
The more big then embossed pattern of the pressure generally applied in embossing process is more clear, but embossing pressure is bigger simultaneously and meeting
Cause gold stamping pattern by severe crush, may cause gold stamping pattern tarnish, and practices the gold stamping print for also reflecting embodiment 1
In the technique being embossed after spending, the embossing pressure that gold stamping pattern can bear is limited, exceeds certain value rear triangle in embossing pressure
Gold stamping pattern on fabric has the tendency that dimmed mute.Therefore applicant attempts to weaken between embossing cylinder and gold stamping pattern
Active force, it is desirable to which embossing pressure, which can be improved, again can slow down extruding of the embossing pressure to gold stamping pattern.Similarly in view of embossing temperature
More high then embossed pattern is also more clear, the drive and the excessively high function of glue coating mobility that will lead to gold stamping pattern of embossing temperature becomes larger
The coat of metal is displaced and the gold stamping pattern gloss of impression, therefore applicant also attempts barrier embossing heat and is transmitted to function of glue coating, wishes
Prestige can be improved embossing temperature again and can be reduced influence of the high temperature to function of glue coating.
Specific step is as follows for the method being embossed again after the gold stamping stamp of the present embodiment 2:
(1) it makes triangular fibre fabric: selecting cross section to be spun into fabric for the terylene triangular fibre of triangle and obtain
Triangular fibre fabric.
(2) gold stamping stamp: open width is put into roller together after being respectively bonded above-mentioned triangular fibre fabric with gold stamping mould paper
Formula gilding press, and moved with the speed of 20m/min.
As shown in Fig. 2, wherein the gold stamping mould paper include PE film ground layer 10 and be fixed on PE film ground layer point
From coating 20 and the magnetosphere being sequentially laminated in breakcoating 30, the coat of metal 40, thermal insulation layer 50 and function of glue coating 60.Institute
State the silicone resin layer that breakcoating selects that as the temperature rises viscosity gradually dies down;The magnetosphere selects ferriferous oxide magnetic
Property material, such as ferroso-ferric oxide;The coat of metal aluminium;The thermal insulation layer selects methyl polysiloxane, aminomethyl phenyl
The organosilicons heat-insulating material such as polysiloxanes, vinyl polysiloxane;The function of glue coating selects polyurethane, polystyrene, poly- third
As the temperature rises that viscosity gradually becomes strong temperature-sensitive adhesive layer, and function of glue coating for any one or more than one in olefin(e) acid ester
It is bonded with dacron surface.
The operating parameter for adjusting gilding press applies 4 tons of pressure and 135 DEG C of temperature to triangular fibre fabric and gold stamping mould paper
Degree, make gold stamping magnetosphere, the coat of metal, thermal insulation layer and function of glue coating on gold stamping mould paper adhere to dacron surface formed it is gold stamping
Pattern.
(3) gold stamping mould paper substrate is removed: by triangular fibre fabric together with gold stamping mould paper after to gold stamping stamp
Clot is put in oven, is cooled down at 50 DEG C for 24 hours afterwards by the PE film ground layer of gold stamping mould paper and breakcoating from triangular fibre
Fabric surface strips down.
(4) it is embossed: will be by step (3) treated triangular fibre fabric open width under the movement speed of 20m/min
It is put into roller embossing machine, is 4 tons in pressure, temperature is 180 DEG C, 195 DEG C, 215 DEG C, 230 DEG C, 250 DEG C, or in temperature
Be 195 DEG C, pressure be make to be carved under 3.75 tons, 4 tons, 4.25 tons, 4.5 tons, 4.75 tons pattern and have on gilding film paper
The roller of magnetosphere same magnetic apply pressure and heat in triangular fibre fabric surface, so that dacron surface is formed bumps
Decorative pattern, i.e. embossed pattern.Wherein the embossing magnetosphere is identical as magnetosphere magnetism.Triangular fibre is knitted after embossing
Object clot.
(5) magnetic of triangular fibre fabric surface pickling: is cleaned using the concentrated nitric acid that concentration is 68~98% at normal temperature
Property layer.
Magnetosphere in above-mentioned technique, can also be independently of boiling hot other than being arranged between breakcoating and the coat of metal
Magnetic material is coated in gold stamping patterned surfaces, then that is, after completing gold stamping stamp and removing gold stamping mould paper substrate by golden mould paper
Carry out subsequent embossing and pickling processes.
As a comparison, applicant by triangular fibre fabric in the case where no magnetosphere and thermal insulation layer in different embossing
Embossed technology processing is tested after carrying out gold stamping stamp in the case where pressure and embossing temperature, after increasing magnetosphere and thermal insulation layer
Pattern Analyses Methods for Sensory Evaluation Results it is as follows:
The result shows that in the case where no magnetosphere and thermal insulation layer, gold stamping pattern embossing temperature be increased to 230 DEG C,
Embossing pressure increase to 4.5 ton hour metallic luster start it is low and deep;And after increasing magnetosphere and thermal insulation layer, fabric is in gold stamping print
It is full that gold stamping pattern metal gloss is still able to maintain after spending under up to 4.75 tons of embossing pressure and 250 DEG C of embossing temperature
It is full;Furthermore in practice it can further be seen that under 230 DEG C, 250 DEG C, 270 DEG C of embossing temperature, and in 4 tons or more of embossing pressure
Under power, the concave-convex trace of embossed pattern is become apparent from, and embossed pattern is apparent.
Occur the above results on the one hand be since the magnetosphere on gold stamping pattern and the roller with same magnetic are mutually exclusive,
To slow down the extruding that gold stamping pattern and triangular fibre are subject to, the actual pressure ratio that gold stamping pattern and triangular fibre are subject to
The pressure theoretically applied is small, avoids coat of metal displacement and the case where being unevenly distributed of generation, and gold stamping pattern is made to keep full
Full metallic luster.On the other hand, thermal insulation layer can prevent heat from passing to function of glue coating, the actual heat ratio that function of glue coating is subject to
The heat theoretically applied is small, and function of glue coating Heated Flow is avoided to become larger to be subjected to displacement and may cause the coat of metal and be unevenly distributed
Even situation, so as to keep the full metallic luster of original gold stamping pattern.Meanwhile do not have outside gold stamping pattern magnetosphere and
The region of thermal insulation layer, fabric is identical as the pressure and temperature that theory applies by actual embossing pressure and embossing temperature, more
High pressure makes fabric be extruded more serious at a temperature of, shows and becomes apparent from concave-convex trace, keeps embossed pattern apparent.
It compared with the existing technology, is after the dacron that triangular fibre is made into carries out gold stamping stamp by selecting cross section
Embossing, the coat of metal is uniformly adhered to triangular fibre surface fullly during gold stamping stamp, in subsequent embossing process three
Deformation occurs for angular fibers, and the coat of metal distribution for forming gold stamping pattern does not change, and still keeps the gold of continuous and derivable
Belong to coating surface, the metallic luster that gold stamping pattern can be kept full.And in embossing process, using between magnetosphere and roller
Repulsive force slow down extruding of the embossing pressure to gold stamping pattern, avoid the coat of metal from being displaced;Heat is prevented to pass using thermal insulation layer
To function of glue coating, function of glue coating Heated Flow is further prevented to become larger to be subjected to displacement and may cause the coat of metal and be unevenly distributed
The case where, so that the coat of metal be made to keep smooth, uniform plane distribution, the metal for keeping gold stamping pattern full in fabric surface
Gloss.In addition fabric is cleaned using concentrated nitric acid finally, concentrated nitric acid can be dissolved as magnetospheric ferriferous oxide material
Material, makes the coat of metal be exposed to most surface layer, generates preferably reflection to light, gold stamping pattern is made to show full metal light
