Description

Process for Producing Rugged Fabric

The present invention relates to a method for producing an uneven processed woven fabric composed of two different kinds of fibers, and more particularly, has excellent sharpness and uneven part smoothness of the uneven processed portion, and is rich in variation. The present invention relates to a method of manufacturing a concave-convex processed fabric having a three-dimensional shape. The present invention also relates to a method of manufacturing an uneven processed fabric which can express colored patterns in recesses.

In recent years, woven fabrics with high functionality have been developed, and the use of interior materials in the automotive and architectural fields, as well as in sports or fashion, is expanding. High-functional woven fabrics, so-called woven fabrics having a three-dimensional shape, have formed an uneven surface on the surface of the woven fabric, and have attracted attention because of the three-dimensional, high-quality, or refreshing feeling.

However, as a method of forming such a three-dimensional shape on a woven fabric, a conventional method of physically forming irregularities and a method of chemically forming irregularities are studied and adopted.

The former physical methods include embossing and schreiner processing, which give a form by contact pressure of a roll under high temperature heating. However, since the woven fabric is inserted between the heating rolls under heavy pressure, the hardening of the touch and the flattening of the woven fabric become very large, and the metallic luster due to the thermal roll or the color change may occur. There is a problem that it is impossible to express the pattern.

As the latter chemical method, when printing is performed, as described in Japanese Patent Application No. 47-23709, a chemical agent that shrinks or reduces fibers is mixed with a printing arc to perform treatment. In the case of using a naphthol derivative as a medicament, there is a problem that stains tend to occur when applied because it is poorly soluble in water, and in the case of using amines and alkali metal hydroxides, there is a problem that odors are generated, and that there is a high risk of danger. In order to solve this problem, it is proposed in Japanese Patent Laid-Open No. 2000-96439 to use a mixture of guanidine carbonate in a printing arc. Although this method has the drawback that alkali resistance is required for the used foaming agent, and the usable foaming agent is limited, it is thought that it is an excellent method in terms of uneven reproducibility, environment, and safety.

However, since the methods enumerated so far have to start with the mold making of the thermal and printing screens, there is a problem in that it is very difficult to cope with small quantity processing in terms of time and price. In addition, since the printing arc mixed with chemicals has a high viscosity, it has a low permeability to woven fabrics, and when used for a long woven fabric having a long pile length, the chemicals do not go to the depth of the pile, the irregularities are insufficient, and the surface smoothness is insufficient. There is this. In addition, when the main part is to be colored, a color shrinkage mixture of a fiber shrinkage agent and a dye is produced and drawn out. However, in the aspect of the process, coloring with a single color is limited, and color patterns can be freely expressed. It is extremely difficult to do.

In order to solve such a problem, in recent years, the method of forming a three-dimensional shape by giving a fiber shrink agent etc. to a woven fabric by the ink-jet method is attracting attention.

The inkjet method does not require the formation of a thermal or printing screen, and it is excellent in terms of economics and safety because it is necessary to spray a chemical to the woven fabric only in the necessary amount. Moreover, the resulting three-dimensional shape is very useful because it is extremely dense which cannot be made in the conventional manner.

For example, as a method of forming a three-dimensional model by an inkjet method, there is a method in which a fiber shrink agent such as that disclosed in Japanese Patent Laid-Open No. 10-298863 is sprayed from a nozzle to shrink a pile. In this case, although a high viscosity ink of 100 to 200 cps is used, the ink jet printer device that is popularly used is a low viscosity type ink of about 1 to 10 cps, and thus a new high viscosity ink printing device is needed. In addition, since the ink has a high viscosity, clogging of the nozzle is likely to occur. In addition, since the fiber shrinkage agent is unlikely to penetrate a woven fabric, when used for a long-knit woven fabric, there is a tendency that the chemical does not penetrate deeply into the pile and the irregularities are insufficient. In addition, the permeability of the fiber shrinkage to the pile tends to be uneven, and there is a problem such as lack of smoothness of the concave surface, resulting in an unclear pattern when colored ink is applied to the same place in order to color a colored pattern on the concave surface. .

Therefore, although the inkjet method is considered to be very useful as a method of forming a three-dimensional shape on a woven fabric, a method of manufacturing an uneven processed woven fabric in which unevenness excellent in unevenness smoothness is obtained, and in which uneven color can be colored is not yet found.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for producing an uneven processed fabric having excellent sharpness and uneven smoothness of unevenly processed portions, and having a three-dimensional shape rich in variation. In addition, the present invention provides a method for producing an uneven processed fabric which can freely color the pattern.

That is, the present invention has a single yarn fineness of 4 decitex or less, 20 to 75% by weight of nylon fibers having a total fineness of 110 decitex or less, and a single yarn fineness of 3 decitex or less, and a total fineness of 170 decitex. The manufacturing method of the uneven processed fabric which includes the process of providing a fiber decomposition agent by the inkjet method to the woven fabric which consists of 25 to 80 weight% of polyester fibers which is the following.

It is preferable to provide an ink capable of coloring the polyester fiber or an ink capable of coloring the nylon fiber simultaneously with the fiber decomposing agent.

It is preferable that the fiber decomposing agent is a guanidine weak acid salt.

It is preferable that the said guinidine weak acid salt is guanidine carbonate.

It is preferable that the woven fabric is a reversible knitted fabric.

It is preferable that the reversible knitted fabric is formed by the plating method of the circular knitting.

Moreover, this invention relates to the uneven processed fabric obtained by the said manufacturing method.

The woven fabric used in the present invention is 20 to 75% by weight of nylon fibers having a single yarn fineness of 4 decitex or less and a total fineness of 110 decitex or less, and a single yarn fineness of 3 decitex or less, and a total fiber having a total fineness of 170 decitex or less 25 to 25 fibers. It consists of 80% by weight.

Because the polyester fiber has excellent strength, weather resistance and chemical resistance, the uneven processing woven fabric of the present invention including the polyester fiber can be used in various applications such as sports clothing, fashion clothing, underwear, automotive interior materials, and advertising films. Can be.

Nylon fibers used in the present invention are nylon 6 fibers and nylon 66 fibers and the like.

Among them, nylon 66 fibers are preferred when strength is required such as sports clothes.

In addition, the single yarn fineness of the nylon fiber is 4 decitex or less and preferably 3 decitex or less. As a minimum, it is preferable that it is 1 decitex. If the single yarn fineness exceeds 4 decitex, the thickness of the woven fabric increases, and there is a risk that deviation or defect occurs in decomposition of the polyester fiber. On the other hand, if single yarn fineness is less than 1 decitex, there is a risk that a high concentration cannot be obtained when colored. The total fineness is 110 decitex or less and 78 decitex or less. The lower limit is preferably 11 decitex, and more preferably 33 decitex. If the total fineness exceeds 110 decitex, the thickness of the woven fabric increases, thereby affecting the decomposition of the polyester fiber. On the other hand, if the total fineness is less than 11 decitex, the strength of the woven fabric is low and there is a risk that the recess is torn.

The polyester fibers used in the present invention include polyester fibers made of polyethylene terephthalate and the like, and cationic salt polyester fibers of normal pressure type or high pressure type. Among them, the high-pressure type cation salt polyester fiber is preferable in terms of excellent color reproducibility and color fastness.

In addition, the single yarn fineness of the polyester fiber is 3 decitex or less, preferably 2 decitex or less. The lower limit is preferably 0.1 decitex, and more preferably 0.7 decitex. If the single yarn fineness exceeds 3 decitex, it may be difficult to completely disassemble and remove it, which is a visual, tactile or functional problem. On the other hand, if the single yarn fineness is less than 0.1 decitex, there is a risk that a high concentration cannot be obtained when colored. The total fineness is 170 decitex or less, and 110 decitex or less is preferable. As a lower limit, it is preferable that it is 22 decitex, and it is more preferable that it is 56 decitex. If the total fineness exceeds 170 decitex, the thickness of the woven fabric increases, and thus affects the decomposition of the polyester fiber. The total fineness of the polyester fibers is preferably set to 1 to 3 times the total fineness of the nylon fibers, and more preferably set to 1.2 to 2.5 times. If it exists in this range, a clear three-dimensional shape can also be formed, and when colored polyester fiber, clear colored pattern can be obtained without adjusting a nylon fiber color.

The total fineness of the nylon fiber and polyester fiber can be determined by the use of the woven fabric of the present invention. For example, when used in a running shirt, nylon fibers are 60 decitex or less, polyester-based fibers are 30-60 decitex, and when used in games, golf shirts, and other cut-sos, nylon fibers are 90 decitex or less, poly When the ester-based fiber is used for warm-up of 55-170 decitex, athletics and tennis, it is preferable that the nylon fiber is 80 decitex or less, and the polyester-based fiber is 30-170 decitex.

These nylon fibers and polyester fibers are preferably used by processing with taslan yarn or covering yarn. These processes can change the woven fabric and can be used for various applications.

As the covering yarns, nylon fibers are screened and polyester-based fibers are used as exterior yarns. In this case, the total fineness of the nylon fiber, which is the screening agent, is preferably 110 decitex or less, and more preferably 78 decitex or less. The lower limit is preferably 22 decitex. If the total fineness of the core yarn exceeds 110 decitex, the thickness of the woven fabric increases, and there is a risk of adversely affecting the decomposition of the polyester fiber as described above. When polyester fiber is used as a sheath yarn, the single yarn fineness is preferably 2.5 decitex or less, and more preferably 1.5 decitex or less. The lower limit is preferably 0.1 decitex. If the single yarn fineness exceeds 2.5 decitex, the degradability of the polyester fiber tends to be extremely reduced. Total fineness should be 30 ~ 170 decitex. If the total fineness is less than 30 decitex, the number of coverings is increased in order to suppress the staining of the nylon fiber, which is the screening, and the staining tends to be hardened, and the texture of the woven fabric tends to be hardened. Tends not to progress well.

In the woven fabric used in the present invention, the nylon fibers are 20 to 75% by weight, the polyester fibers are 25 to 80% by weight, and the nylon fibers are 30 to 70% by weight and the polyester fibers are 30 to 70% by weight. If the nylon fiber is more than 75%, that is, the polyester fiber is less than 25% by weight, the three-dimensional appearance can not be expressed clearly, the nylon fiber is less than 20% by weight, that is, if the polyester fiber is more than 80% by weight The strength decrease of the part from which the polyester fiber was decomposed is remarkable, and the woven fabric cannot be maintained.

In addition, the nylon fiber and polyester-based fiber used in the present invention can be combined by a method such as blending, blending, twisting, teaching or the like. In addition, the woven fabric used in the present invention is preferably composed of two kinds of nylon fibers and polyester fibers. However, if the woven fabric is in a range that does not impair the action and effect of the present invention, polyurethane fibers other than nylon fibers, acrylic fibers, etc. It does not matter even if it contains the fiber which is not decomposed by provision of a fiber decomposition agent.

Although the woven fabric used by this invention contains a knitted fabric, a woven fabric, a nonwoven fabric, etc., it does not specifically limit. Examples of the woven fabric include plain weave, twill weave and runner weave. For example, warp knitted fabrics such as flat pieces, flat pieces of rubber pieces and pearl stitches, tricot pieces, cord pieces, atlas pieces, chain pieces and inlay pieces.

Above all, since it is possible to form a rich three-dimensional shape in a variation, a reversible structure composed of polyester fibers mainly decomposing one side of the woven fabric, and the other side of the woven fabric mainly composed of fibers which are not decomposed. Knitting is good. That is, it is a knitted fabric consisting of a polyester fiber layer and a nylon fiber layer. The method for forming the double-sided knitted fabric is possible by a known method and is not particularly limited. Among them, the plating method of the circular knitting (also called a coarse knitting) is excellent for strength support and is used for wear such as washing. There is little occurrence of peeling by. Moreover, as a bubble shape, a napped fabric is good at the point that touch is good. The napped fabric refers to a woven fabric in which the paper tissue is composed of a knitted or nonwoven fabric and has napped fibers. In addition, because the nap is also called a pile, the nap is also called a pile fabric.

The thickness is preferably 5 mm or less, and more preferably 3 mm or less. As a minimum, it is preferable that it is 0.5 mm, and it is more preferable that it is 1 mm. When the thickness exceeds 5 mm, the permeability of the ink that decomposes the polyester fibers described later is liable to occur, and the decomposition and removal of the polyester fibers tends to be insufficient. When it is thinner than 0.5 mm, it becomes difficult to express clearly the visually and tactilely the part which performs a three-dimensional shape.

The production method of the present invention includes a step of applying a fiber decomposing agent to the woven fabric by an inkjet method.

Examples of the fiber degrading agent include guanidine weak acid salts, phenols, alcohols, alkali metal hydroxides and alkaline earth metal hydroxides. Among them, guanidine weak acid salt is preferable because of the large unevenness obtained and excellent in environmental and safety aspects. Above all, compared to other strong alkalis such as caustic soda, pH of aqueous solution is 10-13, and it is hard to corrode the work safety and apparatus, and in the case of coloring fiber, guanidine carbonate is especially effective at lighting with little influence on the dye used. This is good. The reason why the polyester fiber is decomposed by the guanidine carbonate is presumably because the guanidine carbonate is decomposed into urea and ammonia and changed into a strong alkali in the heat treatment step performed after the provision of guanidine carbonate.

The range of 1-50 g / m <2> is good as the provision amount of the said fiber decomposer, More preferably, 5-30 g / m <2> is preferable. When the amount is less than 1 g / m 2, sufficient unevenness tends to be obtained. On the contrary, when the amount exceeds 50 g / m 2, the amount is more than necessary, which tends to be expensive.

In addition, it is preferable to dissolve and use the fiber decomposing agent in that stable discharge is possible for a long time. In this case, the concentration of the fiber decomposition agent is preferably in the range of 10 to 35% by weight, more preferably in the range of 15 to 30% by weight. If less than 10% by weight, sufficient unevenness tends not to be obtained, and if it exceeds 35% by weight, the dissolution limit of the fiber degrading agent is close to the water so that precipitates may occur, causing clogging of the nozzles. There is a tendency to become impossible.

It is preferable that the viscosity of the ink containing the fiber decomposing agent (hereinafter referred to as fibrous decomposable ink) is 1 to 10 cps, and more preferably 1 to 5 cps at 25 ° C. If it is less than 1 cps, the ejected ink droplets may break apart during flight, and the three-dimensional sharpness may be inferior, and if it exceeds 10 cps, it may be difficult to discharge ink from the nozzle because of high viscosity.

In the case of receiving and using a fiber decomposing agent, it is preferable to contain urea because it dissolves in water stably. Urea is an inkjet ink, and it is optimal with little influence on viscosity and surface tension. As content of urea, the range of 0.1-10 weight% is good, More preferably, the range of 0.5-5 weight% is good. If the amount of urea is less than 0.1% by weight, the effect as a solvent is insufficient and the nozzle tends to be clogged. If the amount of the element is more than 10% by weight, the three-dimensional shape of the original woven fabric tends to be insufficient.

Furthermore, in order to prevent the air clogging of a nozzle, it is good to contain at least 1 sort (s) chosen from the group which consists of a polyhydric alcohol, a polyhydric alcohol derivative, and surfactant which added ethylene oxide. As content, the range of 0.1-10 weight% is good, More preferably, the range of 0.5-5 weight% is good. When the amount is less than 0.1% by weight, the effect of preventing the air clogging of the nozzle is lowered, and the ink tends to be clogged, and when the amount is more than 10% by weight, the ink becomes high viscosity and it is difficult to discharge from the nozzle.

Examples of the polyhydric alcohol or polyhydric alcohol derivatives usable in the present invention include glycerin, diethylene glycol, diethylene glycol monomethyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol dimethyl ether, triethylene glycol monomethyl ether, and propylene. Glycol, propylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, trimethylene glycol, polyethylene glycol, polyethylene glycol dimethyl ether and the like.

As surfactants usable in the present invention, ethylene oxide adducts of nonionic and cationic surfactants are preferable. This is because anionic surfactants pose a problem risk in terms of compatibility with the fiber degrading agent and foaming properties.

As nonionic surfactant to which ethylene oxide was added, ether type nonionic surfactant, such as polyoxyethylene alkyl ether, ether ester type nonionic surfactant, such as polyoxyethylene glycerin fatty acid ester, ester type nonionic, such as polyethyleneglycol fatty acid ester Surfactants and the like.

As cationic surfactants to which ethylene oxide has been added, there are ethylene oxide adducts such as aliphatic amine salts and aliphatic quaternary ammonium salts.

Among them, propylene glycol is more preferable in that the work safety is excellent. In addition, ethylene oxide adducts of aliphatic quaternary ammonium salts are more preferable because of their high stability in alkaline aqueous solutions.

Moreover, it is especially preferable that the said surfactant has a low viscosity whose number average molecular weight is 5000 or less. If the number average molecular weight is 5000 or more, the viscosity of the ink is high, and there is a tendency for the ejection stability of the ink to be insufficient.

To the fiber decomposable ink, a drying inhibitor, a preservative, a water-soluble dye, and the like can be added, if necessary.

The fiber decomposable ink is applied to the woven fabric by an inkjet method. By using the inkjet method, the depth and width of the unevenness can be freely adjusted. In addition, there is no restriction of pattern like printing type, and it is possible to freely express dense three-dimensional shape of 1 pixel level. In addition, since the depth of the unevenness can be gradually changed, it is also possible to express a gradation pattern due to the unevenness in addition to the expression range that has been possible by the conventional roll or screen method. In addition, since it does not discharge a large amount of drainage in addition to time, cost and workability, it can be said that it is superior to the conventional method in terms of environment.

The inkjet printing apparatus used in the present invention is a method in which the ink is not heated because it prevents hydrolysis due to heating of the reactor of the reactive dye in the case of using a reactive dye as the coloring ink to be described later and thermal decomposition of the fiber decomposing agent. It is not specifically limited. For example, it is possible to select any of a continuous method such as a charge modulation method, a charge injection method, a micro dot method and an ink mist method, an on-demand method such as a piezo conversion method and an electrostatic suction method. Among them, the piezoelectric method is preferable in that the ink discharge amount is excellent in stability and continuous dischargeability and can be manufactured at a relatively low price.

It is preferable to include the step of forming an ink repair layer on the woven fabric before the step of imparting a fiber decomposing agent to the woven fabric by an inkjet method. By this, the ink repair layer formed can quickly prevent the fiber decomposable ink from being discharged from the nozzle and keep the fiber decomposable ink therein in order to maintain the proper degree.

The ink repair layer is usually formed by an ink repair agent mainly containing a water-soluble polymer. For example, sodium alginate, methyl cellulose, hydroxymethyl cellulose, carboxydimethyl cellulose, starch, guar gum, polyvinyl alcohol, polyacrylic acid, and the like can be given. You may use these in combination of 2 or more types. Among them, carboxymethyl cellulose which is excellent in alkali resistance and excellent in low cost and fluidity is preferable. If necessary, the ink repair layer may contain a reducing agent, a surfactant, a preservative, a light improving agent, and the like.

It is preferable that the ink repair agent is given 1 to 20 g / m 2 in terms of solid content, and more preferably 2 to 10 g / m 2. If the amount is less than g / m2, the ink capacity is lowered, so the ink tends to cut or fall back. If the amount exceeds 20g / m2, the woven fabric becomes hard and the conveyability in the inkjet printer becomes poor. There is a tendency for the acceptor to fall off from the woven fabric.

In addition, the provision methods include a dipping method, a rotary screen method, a knife coater method, a kiss roll coater method, and a gravure roll coater method. Among them, the dipping method is preferable in that the ink receiving layer can be provided not only on the surface of the woven fabric but also on the entire woven fabric, and the woven fabric having excellent ink acceptance capability can be produced.

At the same time as the fiber decomposing agent, it is preferable to provide an ink capable of coloring polyester fibers (hereinafter referred to as polyester fiber coloring ink) or ink capable of coloring nylon fibers (hereinafter referred to as nylon fiber coloring ink). That is, preparing an ink set including the fibrous decomposable ink, polyester fiber coloring ink and nylon fiber coloring ink, and appropriately selecting and drawing the ink according to the presence or absence of irregularities, the color and the density of the pattern of the recesses and the convexities. good. This makes it possible to color the pattern on the recess, which has been conventionally difficult on the same woven fabric, so that only the uneven processing, the uneven processing and the coloring processing of the recesses, the coloring processing of the polyester-based fibers, and the nylon and polyester fibers Various processing, such as a coloring process, can be performed simultaneously.

More specifically, when the three-dimensional shape is expressed on a woven fabric, a fibrous ink is selected and drawn out. Furthermore, when the color pattern is expressed in the recess, the nylon fiber coloring ink is selected and drawn at the same location as the fiber decomposable ink. In addition, when only polyester fiber is colored without three-dimensional shape, polyester fiber coloring ink is selected and drawn out. If only nylon fibers are to be colored, the nylon colored ink should be selected and printed. Depending on the woven fabric to be used, staining of any one of the fibers may result in uneven coloring, white bleeding, or the like of the obtained colored pattern, which may result in poor quality. In such a case, each coloring ink is drawn in the same place, and a polyester fiber and a nylon fiber are colored simultaneously.

As the polyester fiber coloring ink, an ink obtained by dispersing a disperse dye excellent in color fastness, clarity and color development can be mainly used. In addition, when using the ink which disperse | distributed the pigment or cationic salt-type polyester fiber, the ink which accommodated or disperse | distributed a cationic dye can be used.

As the nylon fiber coloring ink, an ink containing a reactive dye, an acid dye or a metal complex dye can be used. The reactive dye is preferably a reactive dye having one kind selected from the group consisting of a monochlorotriadine group, a monofluorotriadine group, a difluoromonochloropyrimidine group, a trichloropyrimidine group, and the like as a reactor. Reactive dyes having other reactors are likely to cause hydrolysis in an alkaline atmosphere, and when the ink containing a fiber decomposing agent is mixed with a woven fabric, the reactor decomposes, and the coloring concentration in nylon fibers is likely to decrease.

As monochlorotriadine type reactive dye, for example, Kayacion (manufactured by Nippon Kayaku Co., Ltd.), Cibacron (manufactured by Ciba Specialty Chemicals), Drimarene (manufactured by Drimarene P: Clariant), Procion (Procion P: DyStar) KP CION (manufactured by KK Chemical Co., Ltd.), and the like. Examples of the monofluorotriadine-type reactive dyes include CIBACRON F (manufactured by CIBA Specialty Chemicals). Examples of the difluoromonochloropyrimidine-type reactive dyes include Levafix (manufactured by Levafix E-A: DyStar). As a trichloropyrimidine-type reactive dye, it is marketed by the name of a name, for example, Drimarene (made by Drimarene X: Clariant).

The colored ink is a set of ink dissolved or dispersed in water at various concentration levels of various colors, and is suitably used depending on the color or density of the pattern portion.

Therefore, the color is not particularly limited. It is universal, but not limited to, having at least four colors of black, black, and three primary colors of yellow, magenta, and cyan. Thus, the content of the coloring pigment is not particularly limited, but considering the practicality, storage stability and discharge stability, the content is preferably 0.1 to 25% by weight based on the coloring ink. When the pigment content is less than 0.1% by weight, the concentration of the colored ink is too low depending on the concentration of the ground color, which is meaningless. If it exceeds 25% by weight, the ink may have high viscosity or poor solubility, resulting in inferior discharge stability.

Although the provision amount is not specifically limited, 1-50 g / m <2> is preferable and 5-30 g / m <2> is more preferable. If the imparting amount is less than 1 g / m 2, there is a tendency that defects such as white streaks of brush marks are more likely to occur, and if it is more than 50 g / m 2, blurring occurs and the image tends to be unclear.

In addition, the colored ink may both contain a drying inhibitor, a preservative, a viscosity modifier and a ultraviolet absorber, if necessary.

In the inkjet method, a fibrous ink and a color ink are added as necessary, followed by heat treatment. When heat-treating, a fiber is decomposed | disassembled, an unevenness | corrugation appears, and when colored ink is given, coloring with fiber is performed.

As a condition of heat processing, it is good to process about 160 minutes at 160-190 degreeC. When the temperature is lower than 160 ° C, the decomposition of the polyester fibers tends to be insufficient, and in particular, the coloring to the polyester fibers tends to be insufficient. When it exceeds 190 degreeC, the coloring by nylon fiber becomes inadequate enough, or a fiber burns or yellows easily. The heat treatment may be selected from dry heat treatment or wet heat treatment. Among them, the treatment by moist heat is more preferable in that the unevenness to be formed becomes good and in the case of simultaneously performing coloring, a good color development can be obtained at the same time.

Furthermore, after the heat treatment, it is preferable to perform a cleaning treatment for the purpose of removing the ink repair layer, the unfixed reactive dye, and especially the decomposition product of the fiber remaining on the woven fabric from the woven fabric. Regarding this washing treatment method, reduction washing with hydrosulfide, surfactant, soda ash, and the like, which are usually carried out, are used.

Moreover, it is more preferable to perform a weight loss treatment at the time of the reduction washing.

By carrying out the weight loss treatment, it is possible to remove it in the case where there is an insufficient decomposition of the fiber and to form a more sharp unevenness.

Although it does not specifically limit as conditions of a weight loss process, For example, you may process for 10 to 60 minutes at the processing temperature of 70-90 degreeC using the weight loss accelerator 1-5 g / L and caustic soda (granule) 2-15 g / L.

Examples of the weight loss accelerator include aliphatic amine salt cationic surfactants, quaternary ammonium salt cationic surfactants of aliphatic amine salts, aromatic quaternary ammonium salt cationic surfactants, heterocyclic quaternary ammonium salt cationic surfactants, and the like.

In this way, the fibrous decomposable ink is applied to the woven fabric, followed by heat treatment and washing to completely decompose and remove the polyester fiber.

According to the production method of the present invention, it is possible to obtain a woven fabric having excellent sharpness and uneven smoothness of the uneven processed portion. In addition, by simultaneously applying the coloring ink, it is possible to express the color pattern in the uneven part, and thus to obtain a high quality three-dimensional printing material having excellent sharpness and deep coloration in the pattern part of the uneven part and the convex part. Moreover, since ink is provided by the inkjet method, it is excellent also in economy and environmental compatibility.

In addition, the uneven processing woven fabric obtained by the manufacturing method of the present invention uses a woven fabric combining a fiber (polyester-based fiber) that is decomposed and removed by applying a fiber decomposer and a fiber (nylon fiber) that does not decompose in a specific ratio. Because the boundary of the uneven surface is very clear. Furthermore, since the fiber decomposing agent is applied by the inkjet method, it is possible to obtain a three-dimensional shape which is superior in sharpness and recessed smoothness as well as attaching only the height difference as in the prior art. In addition, physical expressions such as new cars, strength cars, and air-permeable cars are also possible, and thus a three-dimensional shape rich in variations can be obtained.

Hereinafter, the present invention will be described in detail with reference to Examples of the present invention together with Comparative Examples, but the present invention is not limited by the following Examples. In addition, [%] in an Example and a comparative example shows [weight%].
