Description

Technical Field

[0001] The invention relates to the field of preparation and processing of textile materials, and in particular to a colored fluorescent corrosion-resistant gold and silver wire and a preparation method thereof. Background Art

[0002] Gold and silver thread is a colored fiber with a long history. It is rich in color and dazzling. It can greatly improve the color and brightness of textiles when used in textile fabrics and has a good decorative effect. It is usually used in traditional high-end fabrics such as brocade. In recent years, gold and silver thread, a colored fiber with strong Chinese traditional cultural symbols, has begun to attract more and more attention and show good market prospects.

[0003] The gold and silver threads on the market are currently made of polyester film (PET film) as the base material, and are prepared through processes such as aluminum plating, color coating, mechanical cutting and twisting. Since the side section of the gold and silver threads will be exposed after mechanical cutting, and aluminum has poor acid and alkali resistance and corrosion resistance, it is easy to cause the gold and silver threads to fade and the coating to delaminate during the printing and dyeing process of textiles. Traditional scraping, spraying and other processes are also difficult to achieve effective coating of the side section of the gold and silver threads. Therefore, how to improve the acid and alkali resistance and corrosion resistance of the gold and silver threads is the key to improving their application performance.

[0004] In addition, after twisting, the gold and silver threads will produce a dazzling luster during the day due to the reflection of light, but at night, due to the lack of sunlight, its gorgeous decorative effect will disappear. If the process is improved so that the gold and silver threads can still maintain good color at night, it can not only solve the time limit of the decorative effect of the gold and silver threads, but also play the role of warning signs, improve the safety of night travel, and greatly increase the application scope of gold and silver threads in textiles. In summary, the preparation of colored fluorescent corrosion-resistant gold and silver threads has good practical significance. Summary of the invention

[0005] The purpose of the present invention is to provide a colorful fluorescent corrosion-resistant gold and silver wire and a preparation method thereof, which realizes the coating protection and fluorescent coating finishing of the gold and silver wire cross section, has both good corrosion resistance and excellent night gloss, and can be used for the decoration of textiles such as curtains, wall cloths and clothing.

[0006] To achieve the above objectives, Figure 1 As shown, the technical solution provides a method for preparing a colored fluorescent corrosion-resistant gold and silver wire, comprising the following steps:

[0007] S1: mixing a set ratio of fluorescent powder, disperse dye, dispersant, anti-settling agent and resin to obtain a color fluorescent coating slurry, wherein the resin is an epoxy modified polyurethane resin mixed with a curing agent, a toughening agent and a diluent;

[0008] S2: Winding the mechanically cut gold and silver threads on the surface of the yarn tube of the yarn dyeing machine, adding the color fluorescent coating slurry into the slurry storage tank, and the slurry storage tank is connected with the pores of the yarn tube;

[0009] S3: Controlling the color fluorescent coating slurry to spray from the pores of the yarn tube under set spraying conditions to cover the mechanically cut gold and silver wires, thereby obtaining gold and silver wire monofilaments coated with the color fluorescent coating slurry;

[0010] S4: The gold and silver monofilaments are sequentially pre-baked by an infrared pre-baking device and dried by a hot air drying device to obtain colored fluorescent corrosion-resistant gold and silver wires.

[0011] This scheme adopts the bobbin coating technology to prepare the colored fluorescent corrosion-resistant gold and silver wires. The colored fluorescent coating slurry is coated on the surface of the mechanically cut gold and silver wires through the bobbin coating technology, and the coated gold and silver wires are subjected to the process steps of rewinding, pre-baking the single wires, and drying and curing to form films, so as to give the gold and silver wires a colored fluorescent effect while using the resin to coat the side sections of the gold and silver wires to improve the corrosion resistance of the gold and silver wires. The colored fluorescent corrosion-resistant gold and silver wires obtained by this scheme not only have good corrosion resistance, avoiding the problem of fading of the gold and silver wires and delamination of the coating that is easily caused during the printing and dyeing process, but also have excellent night gloss, and obtain good night decoration effects, and can be used for the decoration of textiles such as curtains, wall cloths and clothing.

[0012] In step S1 , the phosphor is selected from one or more of red phosphor, blue phosphor, purple phosphor, green phosphor and yellow phosphor. The color of the phosphor can be selected according to actual needs.

[0013] In some embodiments, the fluorescent raw materials of the fluorescent powder are mixed evenly and added into a high temperature resistant crucible, which is covered and calcined at high temperature for a period of time to obtain a fired material, which is put into a grinder for grinding and then cleaned and dried to obtain the fluorescent powder.

[0014] In a specific embodiment, the fluorescent raw materials of the phosphor are mixed evenly and added into a high temperature resistant crucible, and then covered and calcined at 135°C for about 60 min to pick out impurities with incomplete color to obtain a fired material, and the fired material is put into a ball mill for grinding, and then washed and dried to obtain the phosphor.

[0015] When the phosphor is red phosphor, the phosphor raw material is: Li 3 PO 4 3 parts, Cu(NO 3 ) 2 3 parts BaSO 4 52 parts MgSO 4 42 copies.

[0016] When the phosphor is a blue phosphor, the phosphor raw material is: K 2SO 4 7 parts MgSO 4 8 servings, Na 2 S 8 parts, SrSO 4 8 parts, CaS 60 parts, NaCl 7 parts, AgNO 3 2 servings.

[0017] When the phosphor is purple phosphor, the phosphor raw material is: Sr(NO 3 ) 2 1 part, CaS 59 parts, Na 2 S 12 parts, MgS 28 parts.

[0018] When the phosphor is green phosphor, the raw materials of the phosphor are: In(NO 3 ) 3 10 copies, K 2 S 3 parts, CaS 54 parts, Na 2 S 13 parts, Ba (NO 3 ) 2 10 servings.

[0019] When the phosphor is yellow phosphor, the raw materials of the phosphor are: Al 2 S 3 3 parts, KNO 3 2 parts, BaS 52 parts, MgS 38 parts.

[0020] In step S1, the disperse dye is one or more of disperse yellow 54, disperse red 60, disperse green SD-6B, disperse blue 6G, and disperse violet B. During the dyeing or coating process, the disperse dye can be well attached to the surface of the gold and silver thread, so that the color is not easy to fall off, and the color fastness of the gold and silver thread in the subsequent use process is improved. Even after a certain degree of friction, washing and other treatments, it can still maintain a relatively stable color, extending the service life of the gold and silver thread and ensuring its long-term effect in textile decoration. At the same time, the disperse dye and the fluorescent powder are co-dispersed in the epoxy resin. While ensuring the color brightness of the color fluorescent coating slurry, it may produce a synergistic effect with the fluorescent powder, so that the gold and silver thread has a normal color decoration effect during the day, and can play a fluorescent role through the fluorescent powder at night, so that the gold and silver thread can maintain a good color performance both during the day and at night, further improving its decorativeness and practicality.

[0021] In some embodiments, the color of the phosphor is identical to or matches the color of the disperse dye.

[0022] In step S1, the dispersant is one or more of dimethylpentanol, polyvinyl butyral, sodium carboxymethyl cellulose, and polyvinyl alcohol. The dispersant can help the fluorescent powder and disperse dyes to be evenly dispersed in systems such as epoxy resins. The fluorescent powder and disperse dyes are usually solid particles or powdery substances, which are easy to agglomerate in liquid resins. The dispersant can reduce the agglomeration tendency between them, so that they are evenly dispersed in the entire slurry, ensuring the uniformity of the composition of the color fluorescent coating slurry, so that the color and performance of the finally prepared gold and silver wires are more uniform and consistent; at the same time, the dispersant adjusts the color fluorescent coating slurry so that it can be smoothly sprayed out from the pores of the yarn tube, and can form a uniform coating on the surface of the gold and silver wire without problems such as flowing, dripping or inability to cover.

[0023] In step S1, the anti-settling agent is one of organic quaternary ammonium salt montmorillonite, oxidized polyethylene wax, and polyacrylamide. The anti-settling agent is used to prevent solid particles in the color fluorescent coating slurry from settling during storage and use. When the color fluorescent coating slurry is left to stand, the solid particles tend to sink due to gravity. The anti-settling agent can prevent the particles from settling to the bottom by increasing the viscosity of the system, forming a thixotropic structure, or adsorbing on the surface of the particles, thereby ensuring that the slurry composition is uniform and the performance of the slurry sprayed each time it is used is consistent, thereby ensuring the quality stability of the gold and silver wire coating and avoiding fluctuations in the color, fluorescent effect, corrosion resistance and other properties of the gold and silver wires due to uneven composition.

[0024] In step S1, the toughening agent added to the resin is selected from one or any combination of monoepoxy compounds, diepoxy compounds, polycarboxylic acids, and polyol esters. This solution overcomes the defects of traditional epoxy-modified polyurethane resins, such as high hardness and easy cracking after film formation, by adding a toughening agent to the epoxy-modified polyurethane resin to improve the toughness of the epoxy-modified polyurethane resin.

[0025] In step S1, the diluent added to the resin is selected from one or any combination of dibutyl ether and acetone. In this solution, the leveling property and film-forming uniformity of the epoxy-modified polyurethane resin are improved by adding the diluent to the epoxy-modified polyurethane resin.

[0026] In step S1, the curing agent is selected from ethylenediamine, which is used to promote chemical reaction with epoxy groups in the epoxy-modified polyurethane resin to initiate the cross-linking and curing process of the resin.

[0027] In the embodiment of this scheme, 10-25 parts of fluorescent powder, 5-15 parts of disperse dye, 3-8 parts of dispersant, 5-8 parts of anti-settling agent and 50-65 parts of resin are mixed to obtain a color fluorescent coating slurry. In addition, the resin contains 5-7 parts of curing agent, 3-5 parts of toughening agent and 10-15 parts of diluent.

[0028] In step S2 and step S3, this scheme adopts yarn bobbin overflow coating technology to coat the mechanically cut gold and silver threads with colored fluorescent coating slurry. By controlling the winding tension of the gold and silver threads on the yarn bobbin, adjusting the winding density of the gold and silver threads and controlling the overflow pressure, it is ensured that the colored fluorescent coating slurry can evenly coat the gold and silver threads on the yarn bobbin.

[0029] like Figure 2 As shown, the gold and silver threads are wound on the surface of the yarn drum of the drum dyeing machine. Specifically, the gold and silver threads after mechanical cutting are wound on the surface of the yarn drum of the drum dyeing machine at a set winding speed under a set traction tension. In some embodiments, the winding density (winding tightness) of the gold and silver threads wound on the surface of the yarn drum of the drum dyeing machine is 0.3 g / cm³-0.4g / cm³, and the winding density is related to the uniformity of the subsequent color fluorescent coating slurry coating on the gold and silver threads. At this density, a certain gap is maintained between the gold and silver threads and has sufficient compactness. Sufficient gaps can provide a good penetration channel for the color fluorescent coating slurry, so that the color fluorescent coating slurry can fully infiltrate each gold and silver thread to ensure the uniformity of the coating. At the same time, appropriate compactness helps to maintain the relative position stability of the gold and silver threads during the coating process, prevent the gold and silver threads from being displaced or loosened under the action of the slurry injection pressure, thereby ensuring that the coating can be evenly and stably coated on the surface of the gold and silver threads.

[0030] In some embodiments, the pulling tension is 16-20N, and the winding speed is 800-1000 m / min. When the pulling tension is stable in this range, the gold and silver wires can be stretched and wound smoothly to avoid overlapping, crossing or uneven density between wires. The control of the winding speed also ensures that each circle of gold and silver wires can be wound on the yarn tube in a relatively consistent state, thereby forming a regular winding structure.

[0031] In step S3, the color fluorescent coating slurry is controlled to spray from the pores of the yarn tube to coat the mechanically cut gold and silver wires under the set spraying conditions, wherein the spraying conditions are a spraying pressure of 0.3-0.45Mpa, a time of 30-60 min, and a temperature of 20-40°C. The spraying conditions of this scheme are directly related to whether the gold and silver wires can be completely infiltrated. This pressure range enables the color fluorescent coating slurry to spray from the pores of the yarn tube at an appropriate speed and force. On the one hand, sufficient pressure can ensure that the color fluorescent coating slurry can overcome the resistance between the gold and silver wires, penetrate into the gaps between the wires and the tiny depressions on the surface of the gold and silver wires, and achieve comprehensive and uniform coating. If the pressure is too low, the color fluorescent coating slurry may not be able to fully penetrate, resulting in a thin coating on the surface of some gold and silver wires or even an uncoated area; on the other hand, too high a pressure may cause the slurry to be sprayed too violently, resulting in uneven coating on the surface of the gold and silver wires, local accumulation or sputtering, and affecting the appearance and performance of the gold and silver wires.

[0032] Step S4 of this scheme is to dry the gold and silver wire monofilaments during the gold and silver wire rewinding process to prevent the gold and silver wires from sticking together in bundles. The gold and silver wire monofilaments should be pre-dried and then dried to avoid uneven coating caused by migration of the slurry.

[0033] In step S4, the gold and silver monofilaments are reeled under the set pulling tension and winding speed, so that the gold and silver monofilaments are pre-baked by the infrared pre-baking device and dried by the hot air drying device in sequence, and the colored fluorescent corrosion-resistant gold and silver wires are obtained. In some embodiments, the set pulling tension is 16-20N, and the winding speed is 80-100m / min. The pulling tension of 16-20N can keep the gold and silver monofilaments in the reeling process with appropriate tension, ensuring that each monofilament can pass through the heating area in a relatively stable state and spacing when passing through the infrared pre-baking device and the hot air drying device. This helps to avoid entanglement, overlap or local accumulation of the filaments, so that each filament can receive heat evenly, thereby achieving uniform drying; the winding speed of 80~100m / min matches the power of the hot air drying device and the curing characteristics of the coating slurry. Within this speed range, the time that the gold and silver wire monofilaments stay in the heating area can ensure that the solvent in the coating is fully volatilized and the resin and other components complete the curing reaction smoothly, while at the same time it will not cause energy waste or low production efficiency due to too slow a speed.

[0034] The arrangement structure of the infrared pre-drying device and the hot air drying device of this scheme is as follows Figure 3 As shown, the gold and silver monofilaments on the bobbin placed on the bobbin stand are pulled under the winding of the bobbin on the other side to achieve rewinding, and in the rewinding process, they are processed by an infrared pre-baking device and a hot air drying device in sequence. The infrared pre-baking device of this scheme is composed of a quartz tube and an electric heating wire that can emit infrared rays. The electric heating wire is set toward the gold and silver monofilaments to achieve pre-baking of the gold and silver monofilaments. In some embodiments, the electric heating wire of the infrared pre-baking device is 2~2.5 kW, the outer diameter of the quartz tube is 12~30mm, the wall thickness is 1.5~2 mm, and the length is 1~1.5 m; in some embodiments, the hot air drying device blows air toward the gold and silver monofilaments, and the power of the hot air drying device is set to 2~4Kw.

[0035] In the second aspect, this scheme prepares a colored fluorescent corrosion-resistant gold and silver wire according to the preparation method of the colored fluorescent corrosion-resistant gold and silver wire mentioned in the first aspect, and forms a colored fluorescent coating on the surface of the mechanically cut gold and silver wire, wherein the colored fluorescent coating is obtained by solidifying the colored fluorescent coating slurry.

[0036] Compared with the prior art, this technical solution has the following characteristics and beneficial effects:

[0037] 1. This solution protects the cut surface of the gold and silver threads with colored fluorescent coating slurry and performs fluorescent coating finishing. It not only has good corrosion resistance, avoiding the problem of discoloration and coating delamination of the gold and silver threads during the printing and dyeing process, but also has excellent night gloss, and obtains colored fluorescent corrosion-resistant gold and silver threads with good night decoration effect, which can be used for the decoration of textiles such as curtains, wall cloths and clothing.

[0038] 2. This scheme uses the bobbin coating technology to coat the gold and silver wire with colored fluorescent coating slurry. By controlling the winding tension and winding ratio of the gold and silver wire on the bobbin, adjusting the winding density (winding tightness) of the gold and silver wire, and controlling the slurry injection pressure, it is ensured that the colored fluorescent coating slurry can evenly coat the gold and silver wire on the bobbin. Compared with the traditional aluminized PET film coating, the bobbin overflow coating technology for gold and silver wire can achieve the coating and protection of the side section of the gold and silver wire, which is beneficial to improve the corrosion resistance of the gold and silver wire.

[0039] 3. In this scheme, the coated gold and silver wire monofilaments are rewound, the monofilaments are pre-baked, and dried to solidify into a film to obtain gold and silver wires coated with a colored fluorescent coating. The monofilaments are dried during the rewinding process to prevent the gold and silver wires from sticking together. The gold and silver wires must be pre-baked and then dried to avoid uneven coating caused by migration of the slurry. BRIEF DESCRIPTION OF THE DRAWINGS
