Description

Technical Field

[0001] The invention relates to the technical field of textile finishing, and in particular to a color enhancing and restoring agent for old clothes and a preparation method and a use method thereof. Background Art

[0002] At present, the main way to deal with old clothes is to discard them directly and burn them later, which causes great environmental pollution. Some old clothes are also recycled and given to others for use, but the utilization rate of this part is relatively low. At present, some new technologies use old clothes as raw materials to re-produce raw materials for papermaking and textiles. For example, in CN110156967A, old clothes are soaked, cracked, filtered, decolorized, purified, and polymerized to make PET raw materials. In CN103388188A, old clothes are washed with organic alcohol, shredded, and dissolved in ionic liquid to obtain colored fibers.

[0003] On the other hand, some old clothes often carry people’s memories and emotions. Some old clothes may be related to some specific important events and festivals, while some are related to cultural traditions, personal identity, and commemorations of relatives and friends. Therefore, there is an objective demand to refurbish old clothes, but there has been no in-depth research in this field. For old clothes, on the one hand, their colors often fade due to long-term wear; on the other hand, long-term use will also make the strength and elasticity of old clothes worse. Therefore, in terms of refurbishment, it is important to improve its color, feel, elasticity, and strength.

[0004] In addition, for the traditional production of new clothes, there are dyeing and finishing steps to give the new clothes color, pattern, and enhance their strength, but this operation is generally a large-scale operation and is not suitable for small-scale processing by families or individuals. Moreover, the dyeing and finishing in the preparation process of new clothes are generally carried out by immersion at a high temperature of more than 120°C, or by processing through immersion equipment, and families often do not have such conditions.

[0055] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in further detail below.

[0056] The present invention provides a color enhancing and restoring agent for old clothes, which comprises the following components in parts by weight:

[0057] 15-25 parts of fluoroalkyl modified amino silicone oil, 5-10 parts of polyether modified vinyl silicone oil, 2-5 parts of fatty alcohol polyoxyethylene ether, 3-10 parts of sodium dioctyl sulfosuccinate, 0.5-2 parts of sodium polyoxyethylene fatty alcohol ether sulfate, 5-10 parts of propylene glycol, and 50-75 parts of water; Based on the above-mentioned old clothing color enhancer and refresher, firstly, when the old clothing fibers are worn, the old clothing color enhancer and refresher can be well wrapped on the fiber surface, making the surface uneven and flat, reducing the fiber heads caused by wear, effectively improving the color, strength and elasticity of the old clothing, and optimizing its feel. Second, when there may be various traces of pollution on the old clothing, it forms a good wrapping of the old clothing fibers, while traditional clothing finishing agents are often difficult to form a good wrapping in the presence of stains, especially oily stains. Third, through the cooperation of a specific emulsification system and emulsification process, the old clothing color enhancer and refresher is well dispersed. Fourth, it can be processed at room temperature, which greatly simplifies the processing process.

[0058] Preferably, in some embodiments, the old clothes color enhancing and restoring agent may also include some other components, such as fragrance, preservative, pH adjuster, etc., but not limited thereto.

[0059] Specifically, the fluoroalkyl modified amino silicone oil is mainly made of the following raw materials in parts by weight:

[0060] 90-100 parts of the first organosilicon monomer, 1-5 parts of the first silane coupling agent, 1-5 parts of the fluoroalkyl monomer, and 0.001-0.2 parts of the first catalyst;

[0061] The first silane coupling agent is a methoxysilane coupling agent or an ethoxysilane coupling agent, and the fluoroalkyl monomer is a fluorine-containing acrylate or a fluorine-containing methacrylate. The fluoroalkyl-modified aminosilicone oil prepared based on the above raw materials in parts by weight can form a good wrapping film at room temperature, and the fluorine of the side chain of the fluoroalkyl-modified aminosilicone oil is well arranged, effectively playing the role of improving color, strength and elasticity.

[0062] Specifically, the first organosilicon monomer can be selected from one or more of octamethylcyclotetrasiloxane, hexamethylcyclotrisiloxane, tetramethyltetraphenylcyclotetrasiloxane, and tetraethylcyclotetrasiloxane commonly used in the art, but is not limited thereto. Preferably, in one embodiment, the first organosilicon monomer is octamethylcyclotetrasiloxane, which has high reaction activity and high conversion rate.

[0063] Specifically, the first organosilicon monomer is used in an amount of 90 to 100 parts, exemplarily 92 parts, 94 parts, 96 parts or 98 parts, but not limited thereto. Preferably, the first organosilicon monomer is used in an amount of 92 to 100 parts, more preferably 94 to 98 parts.

[0064] Specifically, the fluoroalkyl monomer can be selected from one or more of trifluoroethyl methacrylate, dodecafluoroheptyl methacrylate, and tridecafluorooctyl acrylate; but it is not limited thereto. The above-mentioned fluoroalkyl monomer can give the old clothes good softness and enhance their strength after polymerization with the first organosilicon monomer. Preferably, in one embodiment, the fluoroalkyl monomer is selected from dodecafluoroheptyl methacrylate, which has a longer carbon chain length, further optimizes the wrapping performance of the old clothes color enhancer and rejuvenation agent on the old clothes fibers at low temperatures, and has stronger oxidation resistance.

[0065] Specifically, the amount of the fluoroalkyl monomer is 1 to 5 parts. If the amount of the fluoroalkyl monomer is too large, the water-repellent function of the fluorine atom will make it difficult for the old clothing refresher to wrap the old clothing fibers well at a lower temperature. Exemplarily, the amount of the fluoroalkyl monomer is 1.5 parts, 2 parts, 2.5 parts, 3 parts, 3.5 parts, 4 parts or 4.5 parts, but not limited thereto. The preferred amount of the fluoroalkyl monomer is 2 to 5 parts.

[0066] Preferably, in one embodiment of the present invention, the weight ratio of the first organosilicon monomer to the fluoroalkyl monomer is controlled to be 100:2.5 to 100:4. By controlling the ratio of the two and compounding with other components in the overall old clothing color enhancement and rejuvenation agent, various properties of old clothing fibers can be improved when fluorine is introduced, and the problem of difficulty in forming a good wrapping of old clothing fibers caused by excessive fluorine can be avoided.

[0067] Specifically, the first silane coupling agent is selected from one or more of γ-piperazine propyl methyl dimethoxy silane, N-(γ,-dimethylaminopropyl)-γ-aminopropyl methyl dimethoxy silane, γ(methacryloyloxy)propyl trimethoxy silane, Nβ(aminoethyl)γaminopropyl methyl dimethoxy silane, and γdiethylenetriaminepropyl methyl dimethoxy silane, but is not limited thereto. Preferably, in one embodiment, the first silane coupling agent is selected from N-(γ,-dimethylaminopropyl)-γ-aminopropyl methyl dimethoxy silane.

[0068] Specifically, the amount of the first silane coupling agent is 1 to 5 parts, exemplarily 1.5 parts, 2 parts, 2.5 parts, 3 parts, 3.5 parts, 4 parts or 4.5 parts, but not limited thereto, preferably 2 to 5 parts.

[0069] Specifically, the first catalyst is a strong base, which may be one or more of sodium hydroxide, potassium hydroxide, lithium hydroxide, and tetramethylammonium hydroxide, but is not limited thereto. Preferably, in one embodiment, the first catalyst is tetramethylammonium hydroxide.

[0070] Specifically, the amount of the first catalyst is 0.001 to 0.2 parts, and illustratively 0.005 parts, 0.01 parts, 0.03 parts, 0.08 parts, 0.12 parts, 0.16 parts or 0.19 parts, but not limited thereto.

[0071] Specifically, in one embodiment, the preparation method of fluoroalkyl modified amino silicone oil comprises the following steps:

[0072] S11: mixing a first organosilicon monomer, a first silane coupling agent, a first catalyst, and a first solvent, and heating the mixture to 80 to 90° C. to obtain a first reaction base material;

[0073] The first solvent may be toluene or isopropanol, but is not limited thereto. Toluene is preferred. The volume ratio of the first solvent to the first organosilicon monomer is 100:50 to 100:80. By introducing the first solvent, the first organosilicon monomer and the first silane coupling agent can be well dispersed, thereby improving the conversion rate of subsequent reactions.

[0074] S12: mixing the fluoroalkyl monomer with the first solvent to obtain a second reaction base material;

[0075] The first solvent may be toluene or isopropanol, but is not limited thereto. Toluene is preferred. The volume ratio of the first solvent to the fluoroalkyl monomer is 100:30 to 100:80.

[0076] It should be noted that there is no particular order for steps S11 and S12. Step S11 may be performed first, and then step S12, or step S12 may be performed first, and then step S11, or both may be performed simultaneously.

[0077] S13: adding the second reaction base material dropwise to the first reaction base material;

[0078] The total duration of the dropwise addition is ≤1h, and the temperature of the first reaction base material is maintained at 80-90°C during the dropwise addition.

[0079] S14: raising the temperature to 110-140° C., reacting for 10-20 hours, cooling down and removing the first solvent to obtain fluoroalkyl-modified amino silicone oil.

[0080] After the reaction is finished, the residual first solvent can be removed by reduced pressure distillation, but the invention is not limited thereto. After the first solvent is removed, acetone-water can be used for multiple extractions and purification, but the invention is not limited thereto.

[0081] The fluoroalkyl modified amino silicone oil prepared by the above-mentioned preparation method realizes the polymerization of the fluoroalkyl monomer and the first silicone monomer, and the old clothing color enhancer and rejuvenation agent prepared by the preparation method is relatively stable after being combined with other emulsifiers, and can be well and directionally attached to the surface of the old clothing fibers, thereby improving the color, strength and elasticity of the old clothing.

[0082] Specifically, in the color enhancer and restorer for old clothes, the amount of fluoroalkyl modified amino silicone oil is 15 to 25 parts. When the amount exceeds 25 parts, the hydrophobicity is too strong, which easily leads to emulsion demulsification and fails to form a good coating on the fibers of old clothes at room temperature. When the amount is less than 15 parts, the feel of the old clothes after treatment is deviated. Exemplarily, the amount of fluoroalkyl modified amino silicone oil is 16 parts, 18 parts, 20 parts, 22 parts or 24 parts, but is not limited thereto.

[0083] Among them, polyether-modified vinyl silicone oil can introduce unsaturated polyether into the side chain of vinyl silicone oil to improve the hydrophilicity of the entire old clothing color enhancer and restorer, so that it can still penetrate and wrap the old clothing fibers well in the presence of various stains. At the same time, the vinyl can also provide good anti-yellowing and cross-linking properties. Specifically, the polyether-modified vinyl silicone oil is mainly made of the following raw materials in parts by weight:

[0084] 50-80 parts of the second organosilicon monomer, 1-3 parts of the second silane coupling agent, 10-20 parts of the polyether, and 0.001-0.2 parts of the second catalyst;

[0085] The second silane coupling agent is a vinyl silane coupling agent, and the polyether is allyl polyoxyethylene ether. The polyether-modified vinyl silicone oil prepared based on the above raw materials has strong hydrophilicity and can be compounded with other emulsifiers and fluoroalkyl-modified amino silicone oil to form a wrapping film on the surface of old clothing fibers at room temperature, thereby improving the color, strength and elasticity of old clothing.

[0086] Specifically, the second organosilicon monomer can be selected from one or more of octamethylcyclotetrasiloxane, hexamethylcyclotrisiloxane, tetraethylcyclotetrasiloxane commonly used in the art, but is not limited thereto. Preferably, in one embodiment, the second organosilicon monomer is octamethylcyclotetrasiloxane, which has high reaction activity and high conversion rate.

[0087] Specifically, the amount of the second organosilicon monomer is 50 to 80 parts, and exemplary amounts are 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, or 78 parts, and preferably 50 to 70 parts.

[0088] Specifically, the second silane coupling agent vinyl siloxane is selected from one or more of divinylmethyl disiloxane, tetravinyltetramethylcyclotetrasiloxane, and vinyltrimethoxysilane. Preferably, in one embodiment, the second silane coupling agent is selected from tetravinyltetramethylcyclotetrasiloxane.

[0089] Specifically, the amount of the second silane coupling agent is 1 to 3 parts, and illustratively 1.4 parts, 1.8 parts, 2.2 parts, 2.6 parts or 2.8 parts, but not limited thereto.

[0090] Specifically, the polyether is allyl polyoxyethylene ether, whose terminal allyl group has strong reactivity and can improve the reaction conversion rate. More specifically, the molecular weight of allyl polyoxyethylene ether is 500 to 2000, exemplified by 500, 800, 1000, 1200 or 1500, but not limited thereto.

[0091] Specifically, the amount of polyether used is 10 to 20 parts, exemplified by 12 parts, 14 parts, 16 parts, 18 parts or 19 parts, but not limited thereto.

[0092] Specifically, the second catalyst is a platinum catalyst, and chloroplatinic acid can be used as an example, but is not limited thereto.

[0093] Specifically, the amount of the second catalyst is 0.001 to 0.2 parts, and illustratively 0.005 parts, 0.01 parts, 0.03 parts, 0.08 parts, 0.12 parts, 0.16 parts or 0.19 parts, but not limited thereto.

[0094] Specifically, in one embodiment, the preparation method of polyether-modified vinyl silicone oil comprises the following steps:

[0095] S21: uniformly mixing the second silane coupling agent, the polyether, the second catalyst, and the second solvent, and heating to 60-65° C. to obtain a third reaction base material;

[0096] The second solvent may be toluene or isopropanol, but is not limited thereto. Preferably, the second catalyst is dispersed in isopropanol and then mixed with toluene, the second silane coupling agent and the polyether. In the solution formed by the second catalyst and isopropanol, the concentration of the second catalyst is 1 to 3 vol%. The volume ratio of toluene to polyether is 100:80 to 100:120;

[0097] S22: uniformly mixing the second organosilicon monomer and the second solvent to obtain a fourth reaction base material;

[0098] The second solvent may be toluene or isopropanol, but is not limited thereto. Toluene is preferred. The volume ratio of the second solvent to the second organosilicon monomer is 100:50 to 100:80.

[0099] It should be noted that there is no particular order for steps S21 and S22. Step S21 may be performed first, and then step S22, or step S22 may be performed first, and then step S21, or both may be performed simultaneously.

[0100] S23: adding the fourth reaction base material dropwise to the third reaction base material;

[0101] The total duration of the dropwise addition is ≤ 0.5 h, and the temperature of the third reaction base material is maintained at 60-65° C. during the dropwise addition. Preferably, in one embodiment, the temperature is maintained at 60-65° C. for 0.3-0.8 h after the dropwise addition is completed.

[0102] S24: raising the temperature to 80-100° C., reacting for 4-10 hours, cooling down and removing the second solvent to obtain a polyether-modified vinyl silicone oil;

[0103] After the reaction is completed, the residual second solvent may be removed by distillation under reduced pressure, but the invention is not limited thereto.

[0104] The polyether-modified vinyl silicone oil prepared by the above-mentioned preparation method realizes low-temperature and high-conversion-rate polyether modification, and effectively improves the hydrophilic properties of the vinyl silicone oil.

[0105] Specifically, in the old clothes rejuvenation agent, the amount of polyether-modified vinyl silicone oil is 5 to 10 parts, exemplified by 6 parts, 7 parts, 8 parts, 9 parts or 9.5 parts, but not limited thereto.

[0106] Preferably, in one embodiment, the weight ratio of the fluoroalkyl-modified amino silicone oil to the polyether-modified vinyl silicone oil is controlled to be 20:5 to 25:8.

[0107] In the present invention, the smoothness, strength and color depth of old clothes are effectively improved by modifying the amino silicone oil with fluoroalkyl. However, the introduction of fluoroalkyl will further enhance the hydrophobicity of the amino silicone oil, making it difficult to use at room temperature. For this reason, the present invention introduces polyether-modified vinyl silicone oil on the one hand, and selects fatty alcohol polyoxyethylene ether, sodium dioctyl sulfosuccinate and fatty alcohol polyoxyethylene ether sodium sulfate for emulsification on the other hand, so as to improve the stability and permeability of the emulsion, so as to facilitate the direct refurbishment of old clothes at room temperature.

[0108] Specifically, the amount of fatty alcohol polyoxyethylene ether is 2 to 5 parts, exemplified by 2.5 parts, 3 parts, 3.5 parts, 4 parts or 4.5 parts, but not limited thereto. In the present invention, fatty alcohol polyoxyethylene ether is a C10 to C13 straight chain fatty alcohol polyoxyethylene ether.

[0109] Specifically, the amount of sodium diisooctyl sulfosuccinate is 3 to 10 parts, illustratively 4 parts, 5 parts, 6 parts, 7 parts or 8 parts, but not limited thereto.

[0110] Specifically, the amount of sodium fatty alcohol polyoxyethylene ether sulfate is 0.5 to 2 parts, exemplified by 0.7 parts, 0.9 parts, 1.3 parts, 1.5 parts or 1.8 parts, but not limited thereto.

[0111] Among them, propylene glycol and water are the main dispersants, which are used to disperse silicone oils and emulsifiers.

[0112] Correspondingly, the present invention also discloses a method for preparing a color enhancing and restoring agent for old clothes, which comprises the following steps:

[0113] S31: preparing a fluoroalkyl-modified amino silicone oil emulsion and a polyether-modified vinyl silicone oil emulsion respectively;

[0114] S32: 15 to 25 parts of fluoroalkyl modified silicone oil, 1 to 3 parts of fatty alcohol polyoxyethylene ether, 0.5 to 2 parts of fatty alcohol polyoxyethylene ether sodium sulfate and 20 to 40 parts of water are uniformly mixed to obtain a fluoroalkyl modified silicone oil emulsion;

[0115] S33: Evenly mix 5 to 10 parts of polyether-modified vinyl silicone oil, 1 to 2 parts of fatty alcohol polyoxyethylene ether, and 10 to 20 parts of water to obtain a polyether-modified vinyl silicone oil emulsion;

[0116] S34: Evenly mix the fluoroalkyl modified silicone oil emulsion, the polyether modified vinyl silicone oil emulsion, the remaining water, 5 to 10 parts of propylene glycol and 3 to 10 parts of sodium diisooctyl sulfosuccinate to obtain a product.

[0117] Correspondingly, the present invention also provides a method for using a color-enhancing and restoring agent for old clothes, which comprises: soaking old clothes with the color-enhancing and restoring agent for old clothes, and then drying; wherein, during soaking, the color-enhancing and restoring agent for old clothes may be diluted with water or not diluted. Specifically, drying may be air-drying at room temperature, air-drying, shade-drying or drying, but is not limited thereto. Specifically, the temperature of the drying treatment is ≤60°C, and more preferably ≤40°C.

[0189] Comparative Example 3

[0190] This comparative example provides a color enhancing and restoring agent for old clothes, which differs from Example 1 in that no polyether-modified vinyl silicone oil is introduced.

CIE Da is the color component from red to green. When it is a positive number, it means that it is reddish, and when it is a positive number, it means that the color is greenish. CIE Db is the color component from yellow to blue. When it is a positive number, it means that it is yellowish, and when it is a positive number, it means that the color is bluish. CIE DC is the saturation. When it is a positive number, it means that the color is brighter, and when it is a positive number, it means that the color is darker. CIE DH is the hue. When it is a positive number, it means that the color is counterclockwise in the CIE chromaticity diagram, and when it is a positive number, it means that the color is clockwise in the CIE chromaticity diagram. CIE DE represents the total color difference, and the relative intensity represents the degree of change in the color depth before and after treatment.
