  Washing process such as traditional stone wash to obtain an old-fashioned color is effective for durable denim materials, etc., but it should be applied to flexible and delicate materials to physically damage the fabric. Was difficult. With regard to uneven dyeing, it has been difficult to obtain a fine uneven dyeing effect with good reproducibility, which is likely to be a rough uneven pattern with the conventional method and looks uniform at first glance. The conventional method of obtaining an iridescent tone effect is different in the method of dyeing warp and weft yarns in different colors, which entails great restrictions on product planning from the stage of fabric design, and requires many complicated steps in the post-processing method. Met.

In view of the above-described conventional circumstances, the present invention is to obtain a three-dimensional color with a clear and shaded tone, shaded tone, iridescent tone, and shading without damaging the fibers even for flexible and delicate materials. Furthermore, it aims at providing the thread | yarn, the fabric, or textiles which fixed the particle | grains of the natural fiber colored with the pigment | dye, and its manufacturing method.

  In order to achieve the above object, in the present invention, unlike conventional coloring methods using dyes and pigments, natural fiber particles adsorbed with dyes and yarns, fabrics or textile products are paired as positive and negative in a water bath. Ions were ionized and the particles were adsorbed onto yarns, fabrics or textiles by Coulomb attraction and subsequently fixed with a binder. In addition, the adsorbed particles are partially washed away, or the ionization of the yarn, fabric, or textile product is processed unevenly, so that the fabric is worn, unevenly dyed, iridescent, and three-dimensional with clear colors and shades. Gave a different color.

  Natural fiber particles include cellulosic fibers such as hemp and kenaf, and particles obtained by finely pulverizing protein fibers such as silk and wool, as well as chitosan obtained by treating fiber such as crab shells. Particles could also be used. The particle diameter of the natural fiber is preferably appropriately large in order to obtain an old feeling and uneven dyeing effect, but if it is too large, it tends to precipitate in a water bath and the efficiency of the adsorption treatment decreases. Therefore, moderately pulverized particles having a particle diameter of about 1 to 20 μm were used.

  The pigments used for coloring natural fiber particles are the synthetic dyes used for normal dyeing, considering the nature of the material of the particles, color tone, dyeing fastness, etc. together with the product's use and required consumption scientific performance. Selected from natural pigments. In order to increase the amount of natural pigment adsorbed and to improve dyeing fastness, the natural fiber particles were cationized or anionized before dye adsorption, if necessary. In addition, as in the case of dyeing with ordinary natural dyes, it was possible to change the hue or improve dyeing fastness by metal mordanting.

  The colored particles were adsorbed on the fabric or the textile product while both were present in a water bath with stirring. In order to efficiently adsorb the particles to the fiber or fabric, an attractive force is required between them, and in the present invention, a Coulomb force is used as the attractive force. The particles were adsorbed between the fibers by stirring colored particles and yarns, fabrics or textiles that are ionic in positive and negative pairs in water in the same bath. If the colored particles and the yarn, fabric or fiber product are not ionic, they had to be anionized or cationized so as to have opposite charges. However, for example, when the material itself has ionicity, such as silk, it was possible to perform the adsorption treatment of the colored particles without performing the ionization treatment.

  In order to impart a three-dimensional color with a clear, shaded, shaded tone or shade on a fabric or textile product on which colored particles are adsorbed, the following method was used. In order to obtain a fine uneven finish, the ionization treatment of the fabric and the fiber product was performed uniformly, and the colored particles were adsorbed in an appropriately adjusted stirring state. In order to obtain an old-fashioned color, the colored particles adsorbed on the fabric and the textile product were partially washed away before the fixing with the binder. In order to express the pattern unevenness, the ionization treatment of the fabric or the textile product was performed unevenly to obtain a pre-designed pattern. Conventional methods such as squeezing, textile printing, and spraying by spraying could be used as a method for nonuniform treatment. A clear three-dimensional color of iridescent tones and shades was obtained by localizing the colored particles at a high concentration inside the fiber bundle where the colored particles are easily adsorbed and held. By adsorbing two or more kinds of colored particles of different colors or by combining ordinary dyeing and coloring with colored particles, three-dimensional colors with iridescent tones and clear shadows were obtained more effectively.

  In order to fix the colored particles adsorbed by the Coulomb attractive force on the yarn, fabric or fiber product with sufficient firmness, a treatment with a binder was performed. The binder treatment was carried out by drying or heat treatment after the particles were adsorbed onto yarns, fabrics or textile products, or after the step of imparting the effect of an aging tone or uneven dyeing, and immersed in a solution containing the binder.

Since the present invention is configured as described above, the following effects can be obtained.

By adsorbing and coloring natural fiber particles having a particle diameter of about 1 to 20 μm by Coulomb force, it is possible to impart a three-dimensional color with an antique tone, uneven dyeing style, iridescent tone, and shading. When colored particles are adsorbed by uniformly treating anion or cationization of yarns, fabrics or textile products, natural fiber particles are much larger than dyes or pigments. Uneven dyed finish can be obtained with good reproducibility.

  Since the colored particles adsorbed to the fabric or the textile product by the Coulomb force are not firmly fixed, it is possible to express a feeling of wear and fading by partially washing off. Unlike the conventional washing process, this method does not give a physical force enough to damage the fiber material, so that it can give a unique color expression that fades even with a soft and delicate material such as knit.

As a pretreatment of yarns, fabrics or textiles that adsorb colored particles, anionization or cationization is treated non-uniformly using conventional techniques such as drawing, printing, spraying according to a pre-designed pattern, Particle adsorption can be finished in an uneven dyeing style as designed.

By fixing the colored natural fiber particles in a non-uniform state with a density difference between the surface layer and the inside of the fabric, it has a three-dimensional color with iridescent tones and shadows that look different colors depending on the viewing angle. Can be made. In the conventional method, there is a great restriction on the product planning from the fabric design stage, and a complicated multi-step post-processing process is required. However, the method of the present invention can obtain the same effect with a simple process. it can.

Threads, fabrics, or textiles that have colored particles adsorbed on them are made by pulverizing natural fibers even though the colored particles are much larger than dyes or pigments. The texture of the product will not change significantly. Moreover, since it is light even if the particle size is large, it can be easily suspended by stirring in water, and an efficient and reproducible treatment can be performed.

  As natural fiber particles used in the present invention, cellulose fibers such as hemp and kenaf, and particles obtained by pulverizing protein fibers such as silk and wool, as well as chitin which is a fiber such as crab shells are treated. It is also possible to use chitosan particles obtained as described above. The particle diameter of the natural fiber is preferably appropriately large in order to obtain an effect of aging and uneven dyeing, but if it is too large, it tends to precipitate in a water bath, causing inconvenience in adsorption to the fiber or fabric. In order to float by stirring lightly in a water bath, those pulverized to a particle size of about 5 to 15 μm are preferred. Cellulose powder, silk powder, and chitosan powder manufactured by Tosco Central Laboratory, which are commercially available for cosmetics and food use, can be used as they are because they are ground to an average particle size of about 10 μm.

  As the pigment used for coloring the natural fiber particles used in the present invention, those having good dyeability are selected from synthetic dyes and natural pigments according to the properties of the particle material. When dyeing using a synthetic dye, direct dyes, reactive dyes, acid dyes, and the like can be used as in the case of dyeing cellulose fibers and protein fibers. When adsorbing natural pigments, select from among anthocyanin pigments, flavonoid pigments, quinone pigments, diphenyl pigments, benzopyran pigments, tannins, indigo, shell purple, carthamin, pigments contained in herb plants, etc. Can do. As in the case of normal natural dye dyeing, the hue of natural pigments can be changed or dyeing fastness can be improved by metal mordanting.

The fiber material constituting the yarn, fabric or fiber product that adsorbs the colored particles in the present invention is not particularly limited as long as it can be cationized or anionized to adsorb the colored particles. Specifically, cellulose fibers such as cotton, hemp, rayon, cupra and Japanese paper, protein fibers such as silk and hair, semi-synthetic fibers such as diacetate and triacetate, synthetic fibers such as polyester, nylon, acrylic and polylactic acid, and You can choose from these mixed materials.

The ionization treatment performed as a pretreatment for adsorbing the colored particles to the yarn, fabric, or textile product is performed so that the ionicity of the colored particles and the adsorbed material in water becomes a positive / negative pair. As long as the ionicity of a colored particle and a thread | yarn, a fabric, or a textile product is a positive / negative pair, either may be positive and which may be negative. There are no particular restrictions on the chemicals used, and among the chemicals used for normal anionization or cationization treatment, select one that is suitable for the colored particles and the material of the yarn, fabric or textile product. Can do. As the cationizing agent, reactive nitrogen-containing compounds such as quaternary ammonium salts, polyfunctional quaternary ammonium salts, glycidyltrimethylammonium chloride, and cationic surfactants can be used. Examples of the anionizing agent include triazine derivatives such as Sandspace R (manufactured by Clariant Japan Co., Ltd.), commercially available anionizing agents such as EMACOL CT AGENT TR Con 20 (manufactured by Sanyo Dyeing Co., Ltd.), and polyacrylic acid. Polyanionic compounds such as polymethacrylic acid, and alkali metal salts thereof, and sulfonating agents such as 1,4-butanesultone can be used. Further, the fibers and particles having ionicity can be subjected to an adsorption treatment without performing the pretreatment without any treatment.

In order to increase the amount of natural pigment adsorbed and to improve dye fastness, natural fiber particles may be subjected to cationization or anionization treatment before dye adsorption. The cationization and anionization treatment can be performed in the same manner as the ionization treatment performed as a pretreatment for adsorbing the colored particles.

  Adsorption of the colored particles to the yarn, fabric or textile product is carried out by adsorbing both particles in a water bath with stirring. As the type of bath, a dyeing machine which is usually used for the dyeing method of yarn dyeing, cloth dyeing and product dyeing can be used. The bath ratio can be set to an appropriate condition according to the dyeing machine, but since the adsorption speed is increased by the Coulomb attractive force, an efficient treatment can be performed even at a bath ratio higher than the normal dyeing condition. If the amount of the colored particles used is too large, fixing with the binder becomes difficult. Therefore, the maximum amount is 20% of the weight of the object to be adsorbed, and the treatment is preferably performed in the range of 0.1 to 10%. In order to perform uniform adsorption treatment, the colored particles may be divided and administered to a water bath. As an auxiliary agent, an acidic auxiliary agent such as acetic acid used for normal dyeing, an alkaline auxiliary agent such as soda ash, a nonionic surfactant, and the like can be added to the bath. The temperature of the treatment liquid during the adsorption treatment can be room temperature, and the temperature may be raised to a temperature of 40 ° C. or higher in order to keep the reproducibility of the treatment high without being influenced by seasonal temperature fluctuations.

Fabrics or textiles that adsorb colored particles can obtain three-dimensional colors with clear and shaded colors such as antique, uneven dyeing, iridescent tones, and the like in combination with the following methods. The fine uneven finish has a uniform anionization or cationization treatment for fabrics and textiles, adsorbs colored particles in a properly adjusted stirring state, and the colored particles are larger than conventional dyes and pigments. It can be obtained by using the subtle uneven effect that occurs. The color of the old-fashioned color uses the fact that the colored particles adsorbed to the fabric by the Coulomb attractive force are not completely adhered, and the colored particles adsorbed to the fabric and textiles are partially washed away before fixing with the binder. Can be obtained. The pattern-like uneven dyeing color can be obtained by performing anionization or cationization treatment of a fabric or fiber product according to a pre-designed pattern. As a method of ionization treatment according to the designed pattern, various conventional printing techniques can be applied, such as tie-dyeing technique, anti-dyeing technique using glue and wax, and spraying by spraying. be able to. Clearly three-dimensional colors with iridescent tones and shades can be obtained by coloring particles adhering to the dense areas of the fibers and sticking in a non-uniform state with a concentration difference between the surface layer and the inside of the fabric or textile product. It is done. By adsorbing two or more kinds of colored particles of different colors or by combining ordinary dyeing and coloring with colored particles, it is possible to more effectively obtain iridescent tones and shaded three-dimensional colors.

In the binder treatment, after the colored particles are adsorbed on yarns, fabrics or textile products, or after the step of imparting the effect of aging and uneven dyeing, treatment in a solution containing a binder is followed by dehydration, natural drying or heat treatment. And do it. The binder is used for adhering the pigment to the fiber in pigment printing, and is particularly limited as long as it has appropriate hardness, flexibility, adhesive strength, various durability and stability. Can be used without Although a specific composition cannot be generally stated, acrylic resins, acrylic ester resins, epoxy resins, urethane resins, and the like can be given.
