Description

Old clothes color-enhancing refresher and preparation method, use method thereof TECHNICAL FIELD

[0001] The present application relates to the field of textile finishing, in particular to an old clothes color-enhancing refresher and preparation method, use method thereof. BACKGROUND

[0002] Currently, the main treatment method for old clothes is direct disposal, which is incinerated later, causing great environmental pollution. Some old clothes are also recycled and given to others for use, but the utilization rate of this part is low. Some new technologies currently use old clothes as raw materials to produce papermaking and textile raw materials, for example, in CN110156967A, old clothes are soaked, cracked, filtered, decolorized, purified and polymerized to produce PET raw materials. In CN103388188A, old clothes are cleaned with organic alcohol, cut into pieces and dissolved in ionic liquid to obtain colored fibers.

[0003] On the other hand, some old clothes carry people's memories and emotions, some old clothes may be related to some specific important activities and festivals, and some may be related to cultural traditions, personal identity recognition, and friends' memories. Therefore, there is an objective demand for the refresher treatment of old clothes, but this field has not been studied in depth. For old clothes, one is that the color fades due to long-term wear, and the other is that the strength and elasticity of old clothes deteriorate due to long-term use. Therefore, for refresher treatment, improving the color, hand feeling, elasticity and strength is important.

[0004] In addition, for the traditional production of new clothes, there are steps of dyeing and finishing to give new clothes color, pattern, and improve their strength, but such operations are generally large-scale operations, not suitable for small-scale treatment by families and individuals, and the dyeing and finishing in the preparation process of new clothes are generally impregnated at a high temperature of 120 DEG C or above, or treated by impregnation equipment, which is not available in families.

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

[0056] The present application provides an old clothes color-enhancing refresher, which comprises the following components by weight:

[0057] fluoroalkyl-modified amino silicone oil 15-25 parts, polyether-modified vinyl silicone oil 5-10 parts, fatty alcohol polyoxyethylene ether 2-5 parts, sodium diisooctyl sulfosuccinate 3-10 parts, sodium fatty alcohol polyoxyethylene ether sulfate 0.5-2 parts, glycerol 5-10 parts, and water 50-75 parts; based on the above old clothes color-enhancing refresher, one is that the old clothes color-enhancing refresher can be well wrapped on the surface of the fiber in the case of fiber wear on the old clothes, which makes the surface concave-convex smooth and reduces the fiber head caused by wear, effectively improves the color, strength and elasticity of the old clothes, and optimizes the hand feeling. Two is that in the case of various pollution marks possibly existing on the old clothes, good wrapping of the old clothes fiber is formed, while the traditional clothes finishing agent is often difficult to form good wrapping in the presence of stains, especially oily stains. Three is that the old clothes color-enhancing refresher is well dispersed through the cooperation of a specific emulsification system and emulsification process. Four is that the treatment can be carried out at room temperature, greatly simplifying the treatment process.

[0058] Preferably, in some embodiments, the old clothes color-enhancing refresher can also include some other components, such as fragrance, preservative, pH adjuster, etc., but is not limited thereto.

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

[0060] The first organic silicon monomer is 90-100 parts, the first silane coupling agent is 1-5 parts, the fluoroalkyl monomer is 1-5 parts, and the first catalyst is 0.001-0.2 parts.

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

[0062] Specifically, the first organic silicon monomer can be selected from one or more of octamethylcyclotetrasiloxane, hexamethylcyclotrisiloxane, tetramethyltetraphenylcyclotetrasiloxane, and tetraethylcyclotetrasiloxane, but is not limited thereto. Preferably, in one embodiment, the first organic silicon monomer is selected from octamethylcyclotetrasiloxane, which has high reactivity and high conversion rate.

[0063] Specifically, the amount of the first organic silicon monomer is 90-100 parts, and exemplary amounts are 92 parts, 94 parts, 96 parts, or 98 parts, but are not limited thereto. Preferably, the amount of the first organic silicon monomer is 92-100 parts, and more preferably, the amount is 94-98 parts.

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

[0065] Specifically, the amount of the fluoroalkyl monomer is 1-5 parts, and 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 clothes rejuvenating agent to achieve good wrapping of old clothes fibers at a lower temperature. Exemplary amounts of the fluoroalkyl monomer are 1.5 parts, 2 parts, 2.5 parts, 3 parts, 3.5 parts, 4 parts, or 4.5 parts, but are not limited thereto.

[0066] Preferably, in one embodiment of the present application, the weight ratio of the first organosilicon monomer to the fluoroalkyl monomer is 100:2.5-100:4. By controlling the ratio of the two, as well as the compounding with other components in the overall old clothes color-enhancing refresher, the performance of the old clothes fibers can be improved when fluorine is introduced, and the problem of excessive fluorine causing poor wrapping of the old clothes fibers can be avoided.

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

[0071] Specifically, in one embodiment, the method for preparing the fluoroalkyl-modified amino silicone oil comprises the following steps:

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

[0073] The first solvent can be toluene or isopropyl alcohol, but is not limited thereto. Preferably, the first solvent is toluene. The volume ratio of the first solvent to the first organosilicon monomer is 100:50-100:80. By introducing the first solvent, the first organosilicon monomer and the first silane coupling agent can be well dispersed, and the conversion rate of the subsequent reaction can be improved.

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

[0075] The first solvent can be toluene or isopropyl alcohol, but is not limited thereto. Preferably, the first solvent is toluene. The volume ratio of the first solvent to the fluoroalkyl monomer is 100:30-100:80.

[0076] It should be noted that steps S11 and S12 are not sequential, and step S11 can be performed first, followed by step S12, or step S12 can be performed first, followed by step S11, or both steps can be performed simultaneously.

[0082] Specifically, in the old clothes color-enhancing refresher, the amount of fluoroalkyl-modified amino silicone oil is 15-25 parts. When the amount exceeds 25 parts, the hydrophobicity is too strong, which can easily lead to emulsion breaking and cannot form a good coating on the old clothes fibers at room temperature. When the amount is less than 15 parts, the hand feeling of the treated old clothes is poor. For example, 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] The polyether-modified vinyl silicone oil can introduce unsaturated polyether into the side chain of the vinyl silicone oil, improve the hydrophilicity of the entire old clothes color-enhancing refresher, and thus can still penetrate and wrap the old clothes fibers well in the presence of various stains, and the vinyl can also provide good anti-yellowing and crosslinking properties.

[0088] Specifically, the second silane coupling agent 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 1-3 parts, and is exemplarily 1.4 parts, 1.8 parts, 2.2 parts, 2.6 parts, or 2.8 parts, but is not limited thereto.

[0090] Specifically, the polyether is selected from an allyl polyoxyethylene ether, which has high reactivity of the allyl group at the end and can improve the reaction conversion rate. More specifically, the molecular weight of the allyl polyoxyethylene ether is 500-2000, and is exemplarily 500, 800, 1000, 1200, or 1500, but is not limited thereto.

[0091] Specifically, the amount of the polyether is 10-20 parts, and is exemplarily 12 parts, 14 parts, 16 parts, 18 parts, or 19 parts, but is not limited thereto.

[0092] Specifically, the second catalyst is a platinum catalyst, and is exemplarily selected from chloroplatinic acid, but is not limited thereto.

[0093] Specifically, the amount of the second catalyst is 0.001-0.2 parts, and is exemplarily 0.005 parts, 0.01 parts, 0.03 parts, 0.08 parts, 0.12 parts, 0.16 parts, or 0.19 parts, 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 of the second catalyst and isopropanol, the concentration of the second catalyst is 1-3 vol%. The volume ratio of toluene to polyether is 100:80-100:120.

One half of the old clothes is soaked in the old clothes color-enhancing refresher obtained by example 1 to example 3 and comparative example 1 to comparative example 3 for 3 minutes, and then taken out and wrung dry, and then dried in the sunlight. Colorimetric test (colorimeter Datacolor800), hand feeling test (textile material hand feeling style evaluation instrument, manufacturer: Nantong Hongda Experimental Instrument Co., Ltd.) and breaking strength test (GB / T3923.1-2013) are carried out respectively.

[0193] Specifically, the data of the colorimetric test are shown in Table 1, and the actual photos of the clothes are shown in Figures 1 to 5.
