Disclosure of Invention
The purpose of the invention is: the curtain fabric of the intelligent curtain can be set or changed according to the requirements of users.
In order to achieve the purpose, the technical scheme of the invention is to provide a processing method of an intelligent color-changing curtain, which is characterized by comprising the following steps:
step 1: the method comprises the following steps of (1) taking terylene flame-retardant yarns and silver-plated conductive nylon filaments with electrifying and heating effects as raw materials, wherein the yarn density range of the terylene flame-retardant yarns is between 100d and 120 d; the silver-plated conductive nylon filament is used as a conductive heating material, and the yarn density of the yarn is in the range of 70d-100 d;
step 2: weaving the terylene flame-retardant yarns and the silver-plated conductive nylon filaments in the step 1 into a dyeable and nonflammable surface layer and a double-layer conductive fabric which has conductivity and can be pressurized to ensure that the inner layer of the fabric is heated up through connecting nodes, wherein the surface layer is totally the terylene flame-retardant yarns, and the silver-plated conductive nylon filaments are partially woven into the inner layer;

The surface layer is a five-warp three-fly surface satin weave, and the lining layer is a five-weft two-fly surface satin weave; the number of the connecting nodes between every 5 tissue points is 3, so that the light shading device has excellent light shading effect. Since the back weft contains silver-plated conductive filaments and is poor in coloring property during dyeing and printing, weft floats located on the front weft of the surface layer cover weft structure points located on the back weft of the back layer, and short weft floats located on the back weft are arranged between two weft floats located on adjacent front wefts.

because the inner weft of the fabric structure 2 contains the silver-plated conductive filaments, the temperature can be quickly raised after the two ends of the weft are electrified and pressurized. The curtain fabric needs to be combined with the fabric weave of the 2 nd kind according to the changing effect of the pattern design, and the width of the curtain fabric in the warp direction is equal to the width of the pattern in the warp direction in the whole weft direction by matching the fabric weave of the 2 nd kind on the part of the curtain fabric where the pattern or the color needs to be changed; the weft directions of other areas of the fabric which do not need to be changed are all matched with the fabric weave of the type 1.

Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Fabric (I) process
The invention provides a processing method of an electrothermal discoloration curtain fabric, which comprises the following steps:
step 1: the raw materials used by the electrothermal discoloration curtain fabric are terylene flame-retardant yarns and silver-plated conductive nylon filaments. The yarn density range of the terylene flame-retardant yarn is between 100d and 120 d; the conductive heating material is silver-plated conductive nylon filament, and the linear density range of the yarn is 70-100 d.
The silver-plated conductive nylon filament has the effect of electrification and heating, and is prepared by pretreating nylon multifilament, plating a layer of metal silver on the surface of the nylon multifilament to form a metal silver layer and waiting for use; preferably, in order to ensure that the heating effect reaches a better state, the specification of the silver-plated conductive nylon filament is 70d, and the resistance is 8-10 ohm/m; the specification of the selected polyester flame-retardant yarn is 100 d.
Step 2: weaving the 100d polyester flame-retardant yarns and the 70d silver-plated conductive nylon filaments in the step 1 into a double-layer conductive fabric with a surface layer and an inner layer connected through connecting nodes, wherein the surface layer is completely the 100d polyester flame-retardant yarns, and the double-layer conductive fabric is dyeable, difficult to burn and high in safety factor; 70d of silver-plated conductive nylon filament is woven into the inner layer, so that the fabric is conductive, and the fabric can be heated up by pressurizing.
(1) The surface layer of the double-layer conductive fabric is used for screen printing of thermochromic ink; the inner layer is woven with a conductive material, the surface layer can be heated through heat conduction when the inner layer is electrified, and when the surface layer fabric is heated to a certain value, the thermochromic ink changes color along with the thermochromic ink.
(2) Referring to fig. 1, in the fabric structure of the double-layer conductive fabric, the surface layer and the inner layer are tightly connected through uniformly configured connecting nodes, and as a preferred scheme, the surface layer is a five-warp-three-fly-surface satin weave, and the inner layer is a five-weft-two-fly-surface satin weave; the number of the connecting nodes between every 5 tissue points is 3, so that the light shading device has excellent light shading effect. Since the back weft contains silver-plated conductive filaments and is poor in coloring property during dyeing and printing, the weft floats of the front weft must cover the weft structure points of the back weft, and the short weft floats of the back weft must be disposed between two floats of the adjacent front weft.
(3) The double-layer conductive fabric can be divided into two fabric tissues according to different yarn configurations, the warp and weft of the 1 st fabric tissue are both made of 100d flame-retardant yarns, the warp of the 2 nd fabric tissue is made of 100d flame-retardant yarns, and the weft is made of 100d flame-retardant yarns and 70d silver-plated conductive filaments and is fed in different feeding ratios. Because the inner weft of the fabric structure 2 contains the silver-plated conductive filaments, the temperature can be quickly raised after the two ends of the weft are electrified and pressurized. The curtain fabric needs to be combined with the fabric weave of the 2 nd kind according to the changing effect of the pattern design, and the width of the curtain fabric in the warp direction is equal to the width of the pattern in the warp direction in the whole weft direction by matching the fabric weave of the 2 nd kind on the part of the curtain fabric where the pattern or the color needs to be changed; the weft directions of other areas of the fabric which do not need to be changed are all matched with the fabric weave of the type 1. Therefore, the temperature of the pattern or the color of the curtain fabric needing to be changed can be quickly raised in a plurality of rectangular areas matched with the fabric structure of the 1 st fabric, the problem of pattern positioning offset of screen printing during screen printing is avoided, meanwhile, the large-area use of conductive materials is reduced, the cost is saved, and the energy consumption is reduced. Referring to fig. 2, the combination configuration of two fabric weaves is shown, and in combination with the fabric pattern design of the window covering of this example, the pattern portions of the fabric that need to change color are concentrated and distributed in three areas, which can be divided into a first area, a second area, and a third area.
(4) With reference to fig. 3, the weft yarn configuration of the double-layer conductive fabric is described as follows, as a preferable scheme, in order to realize the effect of changing the printed patterns of the fabric: the weft yarns can be divided into two fabric tissues according to different arrangements of surface warps and surface wefts, wherein the 1 st fabric tissue comprises the following components: surface weft: weft yarn 1; and (3) weft insertion: weft yarn 1; fabric organization of the 2 nd type: surface weft: weft yarn 1; and (3) weft insertion: weft yarn 1/weft yarn 2 is 2/5. The surface weft and the inner weft of the 1 st fabric tissue are all weft yarns 1; the surface weft of the 2 nd fabric structure is weft yarn 1, and the arrangement of the inner weft is weft yarn 1/weft yarn 2 as 2/5. The weft yarn 1 is 100d polyester flame-retardant yarn, and the weft yarn 2 is 70d silver-plated conductive nylon filament. The fabric weave structure of the 1 st fabric weave is the same as that of the 2 nd fabric weave.
(5) Referring to fig. 3, the warp configuration of the double-layer conductive fabric: the surface warp and the surface weft are all 100d polyester flame-retardant yarns except for two side selvedges; the length of the selvedge of the fabric is not less than 5cm, and the configuration of the selvedge warp yarns is as follows: the table meridian: 100d of terylene flame-retardant yarn; internal meridian: 70d silver-plated conductive nylon filament. When the conductive yarns of the cloth edge inner warp are interwoven with the conductive yarns of the 2 nd fabric tissue in each row of the inner weft in the weft yarn configuration, the whole fabric forms a parallel circuit in the inner layer, and the circuit loop can be communicated when a power supply is switched on.
(6) Referring to fig. 4, a schematic diagram of equivalent resistance of the inner layer of the double-layer conductive fabric is shown, in this example, R0 and R0' are equivalent resistance of two fabric edges of the fabric, respectively, R1-1To R1-nRepresents the equivalent resistance of all the conductive weft yarns in the first area in parallel in (3); r2-1To R2-nRepresents the equivalent resistance of all the conductive weft yarns in the second area in parallel in (3); r3-1To R3-nRepresents the equivalent resistance of all the conductive weft yarns in parallel in the third area in (3).
And step 3: and (3) pattern printing is carried out on the double-layer conductive fabric prepared in the step (2) in a screen printing mode, two kinds of slurry are used for printing in the example, one kind of slurry is common printing slurry, the other kind of slurry is thermochromic ink prepared from thermochromic ink powder, the temperature-sensitive thermochromic ink is printed at the designed pattern change position of the fabric and then dried by combining the combined design of the two fabric tissues of the double-layer conductive fabric, and the temperature does not exceed 50 ℃ so as to obtain the electrothermal color-changing curtain fabric.
(1) The printed position of the silk screen printing pattern corresponds to the weave structure of the double-layer conductive fabric in the step 2, the part of the curtain fabric, the pattern or the color of which needs to be changed, is printed on the surface layer of the fabric weave of the 2 nd type in the step 2, and as the conductive material is woven into the inner layer of the fabric weave of the 2 nd type, when the circuit of the fabric is open, the surface layer is under the heat conduction effect of the inner layer, the printed pattern part can be quickly heated up, and when a certain temperature is reached, the pattern printed on the surface layer can generate a corresponding change effect according to the pattern design.
(2) The silk screen printing refers to that a silk screen is used as a plate base, and a silk screen printing plate with pictures and texts is manufactured by a photosensitive plate making method. The screen printing is composed of five major elements, namely a screen printing plate, a scraper, ink, a printing table and a printing stock.
