Description

Technical Field

[0001] The invention relates to the technical field of flame retardant dyes, in particular to a flame retardant yarn dye. Background Art

[0002] The textile industry is paying more and more attention to fire safety, especially in places that require high safety standards, such as building materials, home decoration, vehicle interiors, military and industrial protective clothing. Traditional textiles are easy to burn when exposed to fire, especially synthetic fibers such as polyester and nylon. These fiber materials burn quickly and release toxic gases, posing great risks to people's lives and property. Therefore, how to introduce effective flame retardant properties into textiles has become the focus of the industry.

[0003] Flame-retardant textiles are usually made in two ways: one is to modify the fiber itself to make it flame-retardant; the other is through post-processing, such as using flame retardants to surface treat yarns or fabrics. Compared with fiber modification technology, post-processing is more flexible and can be customized according to different textile needs. Flame retardant treatment. However, traditional flame retardants often have problems such as poor adhesion, poor washing resistance, and affect the dyeing effect, making it difficult to meet the dyeing and flame retardant requirements of yarns at the same time. In addition, with the increasingly stringent environmental regulations, traditional halogen-containing flame retardants are gradually being eliminated due to their toxicity and environmental pollution problems, which has prompted researchers to develop more environmentally friendly and efficient flame retardant solutions.

[0004] Therefore, there is an urgent need for a yarn dye that combines dyeing and flame retardant functions. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a flame retardant yarn dye.

[0006] The above object of the present invention is achieved through the following technical solutions: A flame retardant yarn dye, comprising the following components in parts by weight: Dispersed pigment 50-80 parts; 30-40 parts of carboxymethyl cellulose; Sodium sulfate 20-30 parts; 10-15 parts of sodium acetate; 6-8 portions of isolated soy protein; 3-5 parts of flame retardant particles; 8-10 parts of dispersant; 100-150 parts of deionized water.

[0007] By adopting the above technical scheme, the dye of the present application achieves excellent performance in both dyeing and flame retardancy. First, as the main dyeing component, dispersed colorants can provide uniform color coverage while ensuring the color fastness of dyed yarns in different environments. Dispersed colorants are usually water-insoluble dyes suitable for dyeing synthetic fiber materials such as polyester fibers. The main advantage of disperse dyes is their strong light resistance and water washing resistance, which makes the flame retardant yarn not only have good flame retardant properties, but also have high-quality dyeing effects.

[0008] Carboxymethyl cellulose (CMC) plays a dual role as a binder and stabilizer in this formula. As a water-soluble polymer material, CMC can improve the suspension of dye particles in the dye and prevent precipitation and separation. In addition, CMC can also increase the adhesion between the dye and the yarn, thereby ensuring the uniformity of dyeing, improving the feel of the yarn, and preventing the dye from decomposing or falling off in high temperature or humid environments.

[0009] The introduction of sodium sulfate plays a vital role in the dyeing process, mainly used to adjust the ionic strength of the dye solution. By adding sodium sulfate, the dye can penetrate into the yarn fiber more evenly, thereby enhancing the adsorption capacity of the dye. At the same time, sodium sulfate can also effectively prevent the mutual aggregation of dye particles, further improving the uniformity of dyeing and the brightness of the color.

[0010] Sodium acetate plays a role in adjusting the pH value. During the dyeing process, the pH value has a significant impact on the dyeing effect and the fiber structure of the yarn. The appropriate pH value can prevent the degradation of the dye and protect the yarn fiber from the erosion of the acid and alkaline environment. Sodium acetate also has a certain buffering capacity, which can maintain the stability of the dye solution during the dyeing process and prevent uneven dyeing or color difference problems.

[0011] The introduction of soy protein isolate is to improve the tensile strength and abrasion resistance of yarn. Soy protein isolate is a natural polymer material with good biocompatibility and mechanical strength. In flame retardant yarn dyes, it can enhance the binding force between dye and yarn fiber and prevent the dye from falling off or fading during washing or stretching. In addition, soy protein isolate can also improve the softness of yarn, enhance the touch of yarn, and make the dyed yarn more comfortable and flexible.

[0012] Flame retardant particles are the key component of the dye, which significantly improves the flame retardant properties of the yarn. By combining with the yarn fibers, the flame retardant particles can form a stable carbonized layer in a high temperature or flame environment to prevent the spread of flames and the conduction of heat. This physical barrier not only improves the fire resistance of the yarn, but also delays the burning time of the yarn, increasing the escape time and safety factor. The introduction of flame retardant particles enables the dye to meet the dual needs of fire safety and dyeing quality at the same time.

[0013] Dispersants play a key role in dyes, ensuring that dye particles are evenly dispersed in the solution without aggregation or sedimentation. The choice of dispersant is crucial, as it not only determines the stability of the dye, but also affects the distribution of the dye on the yarn. By using the right dispersant, the dye can cover the yarn surface more evenly, preventing streaks or spots during the dyeing process, thereby improving the overall quality of the dyeing.

[0014] Deionized water as a solvent ensures that all ingredients in the dye formula can be fully dissolved or suspended, thus achieving a uniform dyeing effect. Compared with ordinary water, deionized water does not contain any impurities or ions, which can effectively avoid chemical reactions or precipitation problems during the dyeing process and ensure the full combination of dye and yarn. At the same time, the high purity of deionized water also reduces the corrosiveness of the dye solution, protecting the yarn and equipment from damage.

[0015] In general, the formulation design of the flame retardant yarn dye not only fully considers the dyeing effect, but also greatly improves the flame retardancy, durability and stability of the yarn. The interaction of various components forms a comprehensive and effective dye system that can be widely used in the field of textile dyeing and flame retardancy.

[0016] Furthermore, 5-10 parts of composite particles are added to the flame retardant yarn dye; the composite particles include the following components in parts by weight: 20-30 parts of amylase; 30-40 parts of cyclodextrin composite material; and 5-10 parts of base material.

[0017] Furthermore, the cyclodextrin composite is prepared by stirring and mixing the following components in weight percentage: Cyclodextrin 30-45%; Sodium chloride 10-15%; Polyvinyl alcohol 10-16%; Deionized water balance.

[0018] Further, the substrate includes the following components in weight percentage: Activated carbon 40-50%; Sodium α-olefin sulfonate 10-20%; Dodecyl dimethyl ammonium oxide 10-20%; Fatty alcohol polyoxyethylene ether sodium sulfate residue.

[0019] Furthermore, the preparation process of the composite particles specifically includes the following steps: Step 1: Soak the activated carbon in a mixed solution of sodium α-olefin sulfonate, dodecyl dimethyl ammonium oxide and sodium fatty alcohol polyoxyethylene ether sulfate in proportion, raise the solution temperature to 40-60°C, maintain the soaking time for 30-60 minutes, then filter and vacuum dry to obtain an activated carbon substrate; Step 2: fully mix the raw materials of the cyclodextrin composite material according to a certain proportion, and evenly spray the mixture onto the surface of the substrate using an ultrasonic atomization spraying device to obtain particles a; Step 3: Immerse particle a in the amylase solution for 20-30 minutes, filter, dry by vacuum drying technology, let stand, and perform secondary rapid drying to obtain composite particles.

[0020] The addition of composite microparticles further improves the performance of the flame retardant yarn dye, especially in terms of flame retardancy and yarn durability. Composite microparticles are a multifunctional material composed of multiple components, each of which plays a different role in the microstructure, thus achieving better overall performance.

[0021] The amylase component in the composite microparticles is biodegradable and catalytic. In flame-retardant yarn dyes, amylase can not only improve the stability of the microparticles, but also enhance the adhesion of the dye through catalytic reactions during the dyeing process. Amylase can decompose the complex organic substances in the dye, making it easier for the dye particles to penetrate into the yarn fibers, improving the uniformity and depth of dyeing. In addition, the degradation effect of amylase can also produce a certain amount of gas during the flame retardant process to form an insulation layer, thereby further improving the flame retardant effect.

[0022] As the main component of composite particles, cyclodextrin composites have strong encapsulation and molecular encapsulation functions. The cyclodextrin molecular structure has a special molecular configuration that is hydrophobic inside and hydrophilic outside, which can encapsulate active ingredients such as flame retardants in its molecular cavity to form stable composite particles. This encapsulation effect not only enhances the stability of flame retardant particles in dye liquor, but also effectively protects the decomposition and loss of flame retardants in high temperature environments, thereby improving the flame retardant effect. In addition, cyclodextrin composites can also improve the surface hydrophilicity of yarns, making the flame retardant more evenly distributed on the yarn surface, further improving the comprehensive performance of dyeing and flame retardancy.

[0023] The substrate part provides physical support and dispersion carrier for the composite particles. By combining the substrate such as activated carbon with other components, the composite particles can maintain good dispersion and stability in the dye to prevent precipitation or aggregation. Activated carbon has good adsorption and thermal stability, and can form a stable carbonized layer under high temperature or flame environment, thereby preventing the spread of flames and improving the fire resistance of yarns. In addition, activated carbon can also absorb harmful chemical components in dyes, reduce the release of toxic gases, and further improve flame retardancy and environmental protection.

[0024] After adding the composite particles, the flame retardant effect of the flame retardant yarn dye is significantly enhanced. The composite particles effectively improve the fire resistance and heat resistance of the yarn by forming a uniform flame retardant coating on the surface of the yarn. At the same time, the multifunctional effect of the composite particles makes the flame retardant yarn dye not only have excellent flame retardant effect, but also improve the uniformity, adhesion and durability of dyeing.

[0025] Furthermore, the method for preparing the flame retardant particles comprises the following steps: Step 1: mixing fumed silica gel, 1-butyl-3-methylimidazolium chloride, and ethylene glycol-water solution with intermittent stirring to obtain fumed silica gel-coated ionic liquid particles; Step 2: introducing carbon dioxide gas into the ionic liquid microparticles for 20-30 minutes to obtain flame-retardant microparticles.

[0026] Furthermore, the particle size of the flame retardant particles is controlled to be 10-100 μm.

[0027] The flame retardant particles are prepared by mixing fumed silica, 1-butyl-3-methylimidazolium chloride and ethylene glycol-water solution, and then treated with carbon dioxide, showing excellent flame retardant effect and environmental performance. Fumed silica improves the dispersion and stability of the particles, ionic liquids provide excellent flame retardant properties and low volatility, ethylene glycol-water solution ensures uniform dispersion of the ingredients, and carbon dioxide optimizes the structure of the particles, further enhancing the flame retardant performance.

[0028] Further, the dispersant includes the following components in parts by weight: 1-4 parts of sucrose fatty acid ester; 0.1-2 parts of linear alkylbenzene sulfonate sodium; Fatty alcohol polyoxyethylene ether 0.1-2 parts.

[0029] Furthermore, the chemical components of the sucrose fatty acid ester include, by weight percentage: Sucrose fatty acid triesters 21-42%; Sucrose fatty acid diester 7-16%; Sucrose fatty acid monoester 1-2%; Sucrose fatty acid tetraesters balance.

[0030] Compared with the prior art, the present invention has the following beneficial effects: The present invention achieves a dual improvement in dyeing and flame retardant properties by designing a formula for a flame retardant yarn dye. First, dispersed colorants, as the main dyeing component, provide excellent color fastness and uniform color coverage, and are particularly suitable for synthetic fiber materials such as polyester fibers. Carboxymethyl cellulose (CMC) acts as a binder and stabilizer to enhance the suspension and adhesion of the dye, ensure the uniformity of dyeing, and enhance the feel and durability of the yarn. Sodium sulfate effectively adjusts the ionic strength of the dye solution, ensuring that the dye can evenly penetrate into the yarn fiber, enhancing the adsorption capacity and color brightness, while sodium acetate protects the fiber structure and prevents the occurrence of color difference problems by adjusting the pH value.

[0031] As a natural polymer material, soy protein isolate improves the tensile strength and abrasion resistance of yarn, ensures the adhesion of dyes to yarn, prevents fading, and improves the softness and comfort of yarn. The introduction of flame retardant particles significantly enhances the flame retardant properties of yarn. It forms a carbonized layer in a high temperature environment to prevent the spread of flames, thereby improving the fire resistance and safety of yarn.

[0032] The addition of composite particles further enhances the overall performance of the dye. Amylase improves the adhesion and dyeing uniformity of the dye, while the cyclodextrin composite protects the stability of the flame retardant component at high temperatures through molecular encapsulation, ensuring uniform distribution of the flame retardant. The substrate part provides physical support for the composite particles, improving the stability and dispersibility of the particles. In addition, the preparation process of flame retardant particles effectively improves the flame retardant performance and environmental friendliness of the particles by introducing fumed silica gel and ionic liquids.
