Inorganic particulate can absorb luminous energy and discharges thermal energy, therefore can improve the warming effect of textile.In some implementations
In example, inorganic particulate can be for by the first metal MA, doping metals MBAnd the metal oxide that oxygen is constituted, and this metal oxide
It can be indicated with the following general formula (I):
(MA)(MB)O (I)
In logical formula (I), the first metal MAIt can be zinc, indium or tin, and doping metals MBIt can be tin, aluminium, gallium, iron or antimony.
Above-mentioned inorganic particulate is in single metal (for example, the first metal MA) oxide in adulterate another different metal
(for example, doping metals MB) and formed.In other words, in the first metal MAOxide in, have the first metal M of partAIt is doped
Metal MBReplace.In this way, which the first metal M can be madeAOxide energy rank generate variation.When inorganic particulate is by certain wave
When long light irradiates, the energy of this light is converted into the kinetic energy of the free carrier (free carrier) in inorganic particulate.This
A little free carriers generate collision in the lattice (lattice) of inorganic particulate, and then release thermal energy.For example, some

The macromolecule of pyrrolidone containing can form compound with inorganic particulate (also that is, composite nano-powder 104a).If
There is no the macromolecule of pyrrolidone containing, then inorganic particulate is easy to happen aggregation, causes the partial size increase of inorganic particulate and nothing
The surface area of machine particle reduces.In this way, will make to absorb luminous energy and discharge the efficiency reduction of thermal energy.Therefore, by pyrrole will be contained
The macromolecule of pyrrolidone forms composite nano-powder 104a in conjunction with inorganic particulate, can avoid the aggregation of inorganic particulate, in turn
It can avoid the problem of absorbing luminous energy and release heat energy efficiency reduction.

If the content of the inorganic particulate in composite nano-powder 104a is very little, absorbs luminous energy and discharge the efficiency drop of thermal energy
It is low.Conversely, inorganic particulate is easy to happen aggregation if the content of the inorganic particulate in composite nano-powder 104a is too many, cause
The partial size of composite nano-powder 104a increases and surface area reduces.In this way, which the efficiency for absorbing luminous energy and release thermal energy also can
It reduces.Therefore, the content of the inorganic particulate in composite nano-powder 104a can be adjusted within the scope of specific, to avoid suction
The efficiency for receiving luminous energy and release thermal energy is affected.In some embodiments, inorganic particulate accounts for the 62.5- of composite nano-powder

In other embodiments, the high molecular weight average molecular weight of pyrrolidone containing is 30,000-1,100,000.Other
In embodiment, the high molecular weight average molecular weight of pyrrolidone containing is 300,000-700,000.
The method for preparing composite nano-powder 104a can be any suitable method.For example, in some embodiments,
Inorganic particulate, the macromolecule of pyrrolidone containing and solvent can be mixed, and form colloid (colloid) mixture.Then, by
Solvent is removed by the drying of this colloid admixture, composite nano-powder 104a can be obtained.
In order to obtain colloid admixture, the solubility of the macromolecule of pyrrolidone containing in a solvent should be good.And
And in order to efficiently remove the solvent in colloid admixture, solvent should have lower boiling point.Under above-mentioned condition,
In some embodiments, suitable solvent may include dimethyl acetamide (dimethylacetamide, DMAc), dimethyl Asia
Sulfone (dimethyl sulfoxide, DMSO).However, these solvents are only illustrative solvent, it is not limited to.At other
In embodiment, solvent can be other any suitable solvents.
It in some embodiments, may include spray drying process (spray dry), decompression by the dry method of colloid admixture
The way of distillation (reduced pressure distillation).However, these methods are only illustrative method, not to
It limits.It in other embodiments, can be dry by colloid admixture by other any suitable methods.
In some embodiments, above-mentioned colloid admixture can be directly coated on textile substrate 102.It then, then will
This colloid admixture is dry, and obtains composite fabric 100.As shown in Figure 1, obtained composite fabric 100 can have spinning
Fabric substrate 102, and it is formed in the heat insulating material layer 104 on textile substrate 102.It in such embodiments, can be by
By simple processing procedure, composite fabric 100 is expeditiously made.Therefore, time and the cost of production can be greatly reduced.
It can will be on colloid admixture textile coating substrate 102 by suitable coating process.In some embodiments, it applies
Cloth processing procedure may include intaglio printing (gravure printing), screen painting (screen-printing) processing procedure, roller coating cloth
(roll coating) processing procedure, spray coating (spray coating) processing procedure, blade coating (blade coating) processing procedure, its
His suitable deposition manufacture process or combinations of the above.
After colloid admixture formation, if colloid admixture is placed a period of time (for example, 24 hours), then colloid
Composite nano-powder 104a in mixture gradually can assemble and precipitate, and the partial size of composite nano-powder 104a is caused to increase
Add.Thus, it will reduce the efficiency for absorbing luminous energy and discharging thermal energy.
It in further embodiments, can be dry by above-mentioned colloid admixture (being also known as " the first colloid admixture " below)
Afterwards, dry composite nano-powder 104a is obtained.And then optionally dry composite nano-powder 104a is dissolved in properly
Solvent in, and form colloid admixture (be also known as below " the second colloid admixture ") again.Then, then by this second colloid
Mixture is coated on textile substrate 102 and drying, and obtains composite fabric 100.In such embodiments, through overdrying
Dry composite nano-powder 104a has the advantages that small in size and physicochemical properties are stable.Therefore, multiple by dry nanometer
Closing powder 104a need not can use immediately, and can be reserved for for quite a long time (e.g., from a few days to number under preservation condition appropriate
Month), and more meet with demand.In this way, the flexibility that will can greatly improve processing procedure.
The partial size of composite nano-powder 104a can substantially be equal to the colloidal particle size in colloid admixture.For example,
After the drying of above-mentioned first colloid admixture, the partial size of obtained composite nano-powder 104a can substantially be equal to the first glue
Colloidal particle size in body mixture.In further embodiments, after above-mentioned second colloid admixture being dried, obtained nanometer
The partial size of composite granule 104a can substantially be equal to the colloidal particle size in the second colloid admixture.It therefore, can be by measurement glue
Colloidal particle size in body mixture, and learn the partial size of composite nano-powder 104a.
If the partial size of composite nano-powder 104a is too big, the surface area of composite nano-powder 104a can be reduced.Such one
Come, the efficiency for absorbing luminous energy and discharging thermal energy can be reduced.On the other hand, in order to prepare the lesser composite nano-powder of partial size
104a, it may be necessary to spend more time and cost.It therefore, can be by the median particle diameter (median of composite nano-powder 104a
Particle diameter) D50 adjusts to specific range.In some embodiments, in composite nano-powder 104a
Value partial size D50 is 30-600nm.In further embodiments, the median particle diameter D50 of composite nano-powder 104a is 35-200nm.
The median particle diameter D50 of composite nano-powder 104a is 40-100nm in yet other embodiments,.
Still please refer to Fig. 1, heat insulating material layer 104 with a thickness of T.If the thickness T of heat insulating material layer 104 is too small, absorb
The efficiency of luminous energy and release thermal energy reduces.Conversely, might have the nanometer of part if the thickness T of heat insulating material layer 104 is too big
Composite granule 104a is peeled off, and reduces the yield of final products.Furthermore if the thickness T of heat insulating material layer 104 is too big, can reduce multiple
The gas permeability for closing textile 100, is likely to result in the sense of discomfort of user.It therefore, can be by the thickness T tune of heat insulating material layer 104

In example, the thickness T of heat insulating material layer 104 is 5-80 μm.The thickness T of heat insulating material layer 104 is 10- in yet other embodiments,
50μm.The thickness of heat insulating material layer 104 can be used TECLOCK thickness meter (for example, manufacturer: happyly Japanese；Product type:
SM-112 it) is measured.
Similarly, it if the amount of composite nano-powder 104a is very little, absorbs luminous energy and discharges the efficiency reduction of thermal energy.Instead
It, if the amount of composite nano-powder 104a is too many, the composite nano-powder 104a that might have part is peeled off, and reduces final produce
The yield of product.Therefore, the amount of composite nano-powder 104a can be adjusted to specific range.In some embodiments, with
On the basis of the textile substrate 102 of 100 parts by weight, composite nano-powder 104a is 0.0001-600 parts by weight.In other realities
It applies in example, on the basis of the textile substrate 102 of 100 parts by weight, composite nano-powder 104a is 0.01-100 parts by weight.Another
In some embodiments, on the basis of the textile substrate 102 of 100 parts by weight, composite nano-powder 104a is 0.1-50 parts by weight.
In yet other embodiments, on the basis of the textile substrate 102 of 100 parts by weight, composite nano-powder 104a is 1-10 weight
Part.
In order to keep the color of composite fabric 100 same or similar with the color of textile substrate 102, heat insulating material layer
104 can be the higher film of the transparency.In other words, for wavelength is the visible light of 400-700nm range, heat insulating material layer
The higher the better for 104 light transmittance.In some embodiments, in the range that wavelength is 400-700nm, and heat insulating material layer
Under conditions of 104 thickness T is 6 μm, the light transmittance of heat insulating material layer 104 is 70-83%.In some embodiments, it keeps warm
The visible light transmittance of material layer 104 can be used infrared light/visible absorption spectrum instrument (for example, UV/VIS/NIR spectrometer；System

The value of the light transmittance of the bed of material 104 is the thickness T according to heat insulating material layer 104 and is determined.Therefore, when heat insulating material layer 104
When thickness T is not 6 μm, the light transmittance of heat insulating material layer 104 can be converted by thickness T to be acquired.For example, it is assumed that a certain warming
Light transmittance when material layer 104 is with a thickness of X μm is Y, then the light transmittance when this heat insulating material layer 104 is with a thickness of 6 μm
Following formula conversion can be applied to acquire:
Light transmittance=1- { [6 (1-Y)]/X }.
In order to greatly improve the warming ability of composite fabric 100, heat insulating material layer 104 can for infrared ray absorption ability compared with
High film.In other words, the higher the better for the infrared ray absorption ability of heat insulating material layer 104.It more specifically, is 1 to wavelength,
For the infrared ray of 000-2,500nm range, the higher the better for the absorptivity of heat insulating material layer 104.In some embodiments, exist
Under conditions of wavelength is in the range of 1,000-2,500nm, and the thickness T of heat insulating material layer 104 is 6 μm, heat insulating material layer 104

Product model: JASCO-V570) it is measured.Furthermore the value of the absorptivity of heat insulating material layer 104 is according to heat insulating material layer
104 thickness T and determine.Therefore, when the thickness T of heat insulating material layer 104 is not 6 μm, the absorptivity of heat insulating material layer 104
It can be converted and be acquired by thickness T.For example, it is assumed that absorptivity when a certain heat insulating material layer 104 is with a thickness of A μm is B, then
Absorptivity when this heat insulating material layer 104 is with a thickness of 6 μm can apply following formula conversion and acquire:
Absorptivity=(6 × B/A).
Fig. 2 is the diagrammatic cross-section of the composite fabric 100 ' of other embodiments according to the present invention.Referring to figure 2.,
Composite fabric 100 ' includes textile substrate 102, and is formed in the heat insulating material layer 104 on textile substrate 102.Figure
2 is similar to Fig. 1, the difference is that heat insulating material layer 104 includes composite nano-powder 104a and macromolecule carrier 104b.Fig. 2 and Fig. 1

In order to avoid above-mentioned composite nano-powder 104a peeling, adhesion of the macromolecule carrier 104b to textile substrate 102
Property can be better than composite nano-powder 104a to the adherence of textile substrate 102.Furthermore if macromolecule carrier 104b and nanometer
The compatibility of composite granule 104a is bad, then macromolecule carrier 104b and composite nano-powder 104a may be layered
(delaminate).Also that is, composite nano-powder 104a may can be concentrated in the top or bottom of macromolecule carrier 104b, without
It can be homogeneously dispersed among macromolecule carrier 104b.If macromolecule carrier 104b is layered with composite nano-powder 104a,
It then can not effectively enhance the adherence between composite nano-powder 104a and textile substrate 102.In this way, will be unable to keep away
Exempt from the peeling of composite nano-powder 104a.Therefore, and and nano composite powder good to the adherence of textile substrate 102 may be selected
