Description

FIELD OF THE INVENTION [0001] The present invention relates to a fiber product in which a fluorescent pigment is uniformly adsorbed at low temperature,

The present invention relates to a fiber product in which a fluorescent pigment is uniformly adsorbed at a low temperature and a method for producing the same.

Fluorescence is a phenomenon in which a molecule absorbs light with a short wavelength of high energy and emits light with a longer wavelength. In other words, the fluorescence is slightly longer than the wavelength of the absorbed light because the fluorescence is emitted with slightly less energy than the absorbed light energy. When a molecule absorbs light, it moves up to a higher energy excited state. When the molecule that absorbs light ascends to an excited state, it becomes unstable and emits energy in the form of heat. In another case, it emits light of a wavelength longer than the absorption wavelength and returns to its original ground state. do. Since the energy and wavelength of light absorbed and emitted by different types of molecules are different, each fluorescent material exhibits a variety of fluorescent colors. Fluorescein, Rhodamine, Anthracene, Naphthalimide, Pyrene, Resorufin, Coumarin, and Cyanine are the organic compounds showing fluorescence properties.

Pigment refers to an inorganic or organic colorant on a colored fine particle which is not soluble in water or a solvent. Pigments may be white or colored, mixed with linseed oil, synthetic resin solution, etc., and various paints, printing inks, etc. may be made to color on the surface of the object, or mixed directly with rubber or synthetic resin. Dyes are similar to pigments, which are colored powders that dissolve in water and organic solvents and are mainly used for fiber coloring. Dyes are not suitable for monochromatic pigments because they have transparency and they are mainly used to make a color mixture. Pigments are opaque compared to dyes and have strong tinting and hiding power. They can be divided into organic pigments and inorganic pigments. Inorganic pigments are inorganic compounds made from natural acids or synthetic pigments. It is stable against chemicals or light. Also, the number of colors is smaller than that of organic pigments, the coloring power is small and the color is not clear. Organic pigments generally have lower hiding power, light resistance, solvent resistance, and heat resistance than inorganic pigments. However, the number of colors is large, and there are many pigments with high coloring power and clear colors.

Examples of the organic pigments include dye pigments, azo pigments, phthalocyanine pigments, condensed polycyclic pigments, nitro pigments, nitroso pigments, and fluorescent pigments. Examples of the azo pigments include soluble azo, insoluble azo, condensed azo, azo complex, benzimidazolone azo type, and the like. Examples of the dye-based pigment include basic, acidic,

Examples of the inorganic pigments include oxide types such as titanium dioxide, zinc oxide, iron oxide and chromium oxide, hydroxide types such as alumina and iron oxide sulfur, sulfide types such as zinc sulfide, chromate types such as zinc chromate and strontium chromate, , Sulphate types such as barium sulphate, carbonate types such as calcium carbonate, and other ferrocyanide, phosphate and carbon black types.

Pigments are used as colorants in all fields for the coloring of all artifacts except dye in our surroundings. It is used as a pigment for road, a pigment for printing ink, a pigment for plastic, a pigment for cosmetic, a pigment for ceramics, a pigment for paper, a pigment for stationery, a pigment for rubber, a pigment for construction material, a pigment for leather, to be.

In Korean Patent Publication No. 2008-0029708, "Method of Coating a Resin Composition Pigment or Dye Water with a Resin Composition Pigment or Dye Article ", the first step is to prepare a resin composition dye coating resin by mixing pigment and dye in a resin for fiber coating In the second step, as a yarn dyeing coating process, a yarn wound on a krill is wound around a beam, the yarn of the beam is refined, bleached, washed, dried by an air drying process, coated with a resin pigment of a resin composition pigment, And then the yarn coated with the dyed resin is wound on a beam to dye the yarn. In addition, the fluorescent dye or the light emitting glass powder is mixed with the resin and coated on the yarn by the above-mentioned process.

However, in the case of a method of coating a resin composition pigment or a dye material with a fiber yarn as in the prior art, since the system is coated with a resin composition, the coating material tends to be detached from the fiber due to mechanical friction in a knitting and weaving process, There is a possibility that the fastness to rubbing is weak.

However, in the above prior art, (1) a positive ionizer containing a polyamine-polyamide epiglolohydrin resin is charged into a first salt bath containing fibers to be dyed, and an aqueous solution containing a basic salt such as anhydrous sodium carbonate The cationized fiber through the cationization and curing step of curing the cationizing agent to partially cure at the surface of the fiber by adding a curing agent rapidly adsorbs the anionized organic pigment at the surface due to the strong cationicity of the surface It is obvious that there is a high possibility of causing unevenness. (2) an anionizing agent such as an organic pigment and an aqueous isocyanate-terminated prepolymer in water in a second salt bath containing the fiber treated with a cationic ionic agent. Magnesium sulfate and glacial acetic acid are added to the solution and then the water in the second salt bath is heated and heated to a temperature of 50 to 80 ° C. When magnesium sulfate and glacial acetic acid are added, It is clear that the pigments are likely to cause association and cause unevenness. That is, the contents of the patent do not specifically describe the technical method and principle of uniform dyeing, which is the basic and essential of dyeing technology.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

As used herein, the terms " about, " " substantially, " " etc. ", when used to refer to a manufacturing or material tolerance inherent in the stated sense, Accurate or absolute numbers are used to help prevent unauthorized exploitation by unauthorized intruders of the referenced disclosure.

The 'fiber product' referred to in the present invention refers to an article which can be formed of fibers such as fibers, threads, fabrics such as woven or knitted fabric, clothing, and the like.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a process diagram of a production method for producing a fiber product in which the fluorescent pigment of the present invention is uniformly adsorbed at a low temperature.

As shown in FIG. 1, the method for producing a fiber product in which the fluorescent pigment of the present invention is uniformly adsorbed at a low temperature condition includes a preparation step, a permeator treatment step, a modification step, an ammonium salt treatment step, an adsorption step, , A fixing step, a softening step and a drying step.

In the preparing step, 1.0 to 5.0 g / L of sodium hydroxide, 3.0 to 10.0 g / L of hydrogen peroxide and 1.0 to 3.0 g / L of sodium silicate are added to the processing bath in a step of refining and bleaching the fiber product before the impregnating agent treatment step, Liquid ratio of 1: 3 to 1:20, treatment temperature of 90 to 110 ° C, treatment time of 20 to 60 minutes, refining, bleaching and washing with water.

The penetrant treatment step is a step of immersing the fiber product in a processing bath containing a penetrating agent. The penetration agent is added to the processing bath in an amount of 1.0 to 5.0 g / L, a solution ratio of 1: 3 to 1:20, a treatment temperature of 20 to 120 ° C For 20 to 60 minutes for increasing the permeability of the fiber to the chemical.

The preparing step and the impregnating agent treating step are processes for expressing the drug permeability of the fibers so that the fluorescent pigment can be uniformly treated at low temperatures. In general, the penetrating agent for fibers is generally used in a bathing process together with a dye or a treating agent. In the present invention, after the preparing step for refining and bleaching, a method of further treating the penetrating agent and removing the penetrating agent through sufficient water washing But also to improve the mechanical permeability of the fibers while preventing the remaining penetrant from affecting subsequent processing.

In addition, when only the refining and bleaching process is carried out without an additional impregnation process, it is difficult for all of the treated fibers to have a sufficiently uniform degree of hydrophilicity, and the conditions under which the fluorescent pigment approaches and adsorbs with the fibers become uneven, Is difficult to be uniformly treated. Therefore, when a permeant having a HLB (Hydrophilic Lipophilic Balance) value of 10 to 20 is further treated after the preparation step for scouring and bleaching, sufficient wettability and permeability can be ensured and the fluorescent pigment can be uniformly treated It can provide a foundation for

The modifying step is a step of modifying the fiber surface by immersing the fiber product in a processing bath containing a fiber surface modifier containing diaryldimethyl ammonium chloride polymer. The fiber surface modifier is added to the processing bath in an amount of 0.5-5.0% owf, 1: 3 to 1:20, a treatment temperature of 20 to 100 ° C, and a treatment time of 20 to 60 minutes.

When the surface of the fiber is modified as described above, a cationic agent including a polyamine polyamide epichlorohydrin resin is used in a conventional general method. The polyamine polyamide epichlorohydrin resin is preferably a diethylene triamine, The molecular arrangement is irregular because it is polymerized based on three or more monomers such as diphosphoric acid and epichlorohydrin. Therefore, there is a high possibility that the strength of the cationic surface of the fiber surface is uneven after processing, which limits the uniform treatment of the fluorescent pigment on the surface of the fiber.

In addition, since the strength of cationic strength is relatively weak, durability against washing and the like is not excellent. On the other hand, the diaryldimethylammonium chloride polymer contained in the fiber surface modifier used in the present invention is very regular in molecular arrangement because a single kind of monomer of diaryldimethylammonium chloride is polymerized by chain reaction.

Therefore, after processing, the cationic strength of the fiber surface becomes uniform as a whole, and the fluorescent pigment can be uniformly adsorbed to the fiber surface. Also, since the cationic strength is stronger than the cationic agent based on the polyamine polyamide epichlorohydrin resin, it can exhibit an excellent durability against washing and the like.

The ammonium salt treatment step is a step of immersing a fiber product in a processing bath containing an ammonium salt, wherein 0.1 to 100.0 g / L of an ammonium salt is added to the processing bath, a liquid ratio is 1: 3 to 1:20, a treatment temperature is 20 to 50 ° C, For 5 to 60 minutes to prevent rapid absorption of the fluorescent pigment into fibers and to maintain the dispersion stability of the fluorescent pigment.

The introduction of the ammonium salt when the fluorescent pigment is added to the processing bath is to prevent the fluorescent pigment from being adsorbed rapidly to the fiber and to maintain the dispersion stability of the fluorescent pigment. The modified fiber using the fiber surface modifier in the modification step is uniformly treated with the diaryldimethyl ammonium chloride polymer, and a large number of ammonium groups are located on the surface thereof. Since many of these ammonium groups have a characteristic of strongly adsorbing anionic fluorescent pigments, if fluorescent pigments are directly introduced after the fiber surface modification process, fluorescent pigments are rapidly adsorbed on the fiber surface, resulting in nonuniform results.

Therefore, in order to prevent this, the ammonium salt is added prior to the application of the fluorescent pigment to the processing bath, because when the ammonium salt is dissociated in the processing bath and ammonium ion is generated, an electric charge equivalent to the ammonium group on the surface of the fiber is released, And the charge of the processing liquid are equally balanced, so that the fluorescent pigment can not be rapidly adsorbed to the surface of the fiber and can stay in the processing liquid. If the charge level is larger or smaller than the ammonium group on the surface of the fiber, the dispersion stability of the fluorescent pigment is broken and the adsorbed on the surface of the fiber rapidly, or the possibility of association between fluorescent pigments increases. Namely, the ammonium group in the fiber surface and the ammonium ion in the processing bath are kept in balance to prevent the rapid adsorption of the fluorescent pigment.

The ammonium salt treatment step ammonium salt may be any one or a mixture of two or more of ammonium chloride, ammonium sulfate, ammonium carbonate and ammonium nitrate.

Wherein the adsorbing step is a step of charging a fluorescent pigment into a processing bath containing the ammonium salt and adsorbing the fluorescent pigment to a fiber product, wherein 1.0 to 20.0% owf of a fluorescent pigment is added to the processing bath and the treatment temperature is 20 to 50 ° C, Thereby adsorbing the fluorescent pigment to the fiber.

The particle size of the fluorescent pigment used in the present invention is preferably 1 m or less in terms of adsorption and durability with respect to the fiber product, and the color of the fluorescent pigment is typically a yellow, orange, red, pink, magenta, And other colors can be realized by changing or combining the coloring material.

The fluorescent dye is a step of introducing a pH slide agent into the processing bath into which the fluorescent pigment is added to develop fluorescent hue. The pH slide slurry is added to the processing bath at a pH of 0.1 to 10.0 g / L and a solution ratio of 1: 3 to 1:20, Treating at a treatment temperature of 20 to 50 캜 for a treatment time of 10 to 60 minutes to thereby express the fluorescent color while minimizing the association of the fluorescent pigment.

In order to maximize the fluorescence color and minimize the association of the fluorescent pigment, the pH slide agent is added for the purpose of developing the fluorescent color of the fluorescent pigment as described above.

Generally, glacial acetic acid is used to express the fluorescent hue of fluorescent dyes in the fluorescent dyeing process of polyester fibers. If glacial acetic acid is used for fluorescent pigment dyeing according to this general method, fluorescent pigment is associated and precipitate occurs.

The pH slide agent is known to gradually lower the pH of the dye bath in the acid dye dyeing process to maintain the acidic condition, but is used in the present invention to express the fluorescent hue of the fluorescent pigment. In other words, unlike glacial acetic acid which causes rapid pH change, since the pH slider gradually changes the pH, it can help the fluorescence color expression while minimizing the association of the fluorescent pigment.

The step of homogenizing is a step of adding ammonium salt and neutral salt to the processing bath to which the pH slurry is added to increase the homogeneity. The ammonium salt and the neutral salt are added to the processing bath at a rate of 0.1 to 200.0 g / L, For 10 to 300 minutes so that the fluorescent pigment can be uniformly adsorbed by the fibers under low temperature conditions.

The mixing of the ammonium salt and the neutral salt at a certain ratio as described above is intended to uniformly adsorb the fluorescent pigment on the surface of the fiber.

Generally, in the dyeing process of reactive dyes, the middle dyes play a role of promoting the adsorption of dye to the fiber surface. However, when such a method is directly applied to the fluorescent pigment dyeing, since the strength of the cationic property of the fiber surface treated with the diaryldimethyl ammonium chloride polymer is strong, there is a high possibility that the fluorescent pigment is rapidly adsorbed and causes unevenness. Therefore, in order to prevent this, in the present invention, the neutral salt is mixed with the ammonium salt at a certain ratio. The ammonium salt introduced with the neutral salt is dissociated in the processing bath to exhibit a cationic strength equivalent to that of the ammonium group of the diaryldimethyl ammonium chloride polymer treated on the fiber surface so that the fluorescent pigment is not adsorbed rapidly on the fiber surface do. Therefore, it is possible to uniformly adsorb the fluorescent pigment on the surface of the fiber by mixing ammonium salt and neutral salt for a certain period of time.

The neutral salt may be selected from the group consisting of sodium nitrate, sodium chloride, sodium sulfate, sodium carbonate, potassium nitrate, sodium nitrate, sodium nitrate, sodium nitrate, sodium nitrate, Any one or a mixture of two or more of potassium chloride, potassium sulfate and potassium carbonate may be used.

The mixing ratio of the ammonium salt to the neutral salt is preferably 1:99 to 99: 1 by weight.

The fixing step is a step of fixing a fluorescent pigment immersing the fiber product in a processing bath containing a dye fixing agent. The dye fixing agent is added to the processing bath in an amount of 0.1 to 5.0% owf, and a liquid ratio of 1: 3 to 1:20, 40 to 80 占 폚 for a treatment time of 20 to 60 minutes so that the dyed durability is improved by firmly fixing the dyed fluorescent pigment.

The dye fixing agent may be any one or a mixture of two or more of cationic, anionic, acrylic, urethane and natural sugar.

After the fixing step, the textile article may further include a softener treatment step and a drying step. It is preferable that the softening agent treatment step is performed by charging the softening agent at 1.0 to 100.0 g / L, and the drying step is performed at a treatment temperature of 100 to 180 ° C for a treatment time of 1 to 10 minutes.

The softening agent may be a conventional softening agent such as a silicone type softening agent, a fatty acid type softening agent and the like.
