Description

Eco-friendly solvent and dry cleaning composition containing the same {Eco-friendly solvent and dry cleaning composition containing the same}

The present invention relates to an eco-friendly solvent and a dry cleaning composition containing the same, and more particularly, to a dry cleaning composition containing solketal and its derivatives as a solvent and further containing a specific fragrance to reduce wrinkle formation of fibers. It's about the composition.

In general, washing to remove stains from fibers or clothes can be classified into dry cleaning, which removes stains by dispersing a surfactant in water or dissolves stains in a solvent. A washing method using water and a surfactant is effective in removing water-based contamination, but has limitations in removing oil-based contamination. Dry cleaning is suitable for washing fabrics or clothes unsuitable for a washing process accompanied by a strong dehydration process, and is suitable for removing oily contamination using an organic solvent.

In conventional dry cleaning, petroleum-based or chlorine-based solvents have been mainly used. As the petroleum-based solvent, a hydrocarbon having 10 or more carbon atoms, more specifically, a hydrocarbon having 10 to 13 carbon atoms is used. Petroleum-based solvents have the advantage of excellent cleaning power against oil-based contamination and high volatility, so they are easy to dry. However, there is a risk of fire and explosion due to their low boiling point and high vapor pressure. There is a limit to that. As the chlorine-based solvent, a compound such as PERC, in which 4 chlorine atoms of 2 double-bonded carbons are bonded, is used. Chlorine-based solvents have the advantages of excellent detergency against oily contamination, high volatility and low risk of explosion, but have been found to be toxic substances that can cause cancer to the human body. Petroleum-based and chlorine-based solvents are gradually being limited in their use.

In order to solve the disadvantages of these conventional solvents, various solvents such as glycol ether-based solvents, bromine-containing solvents, and silicone oil-containing solvents have been developed, and a dry cleaning method using liquefied carbon dioxide and a small amount of water are used. Alternatives have also been proposed, such as wet cleaning methods to remove contamination by cleaning.

However, glycol ether-based solvents have attracted attention because of their excellent cleaning power compared to petroleum-based hydrocarbon solvents, but have disadvantages in that they take a long drying time and consume a lot of energy required for drying due to their relatively low volatility. Solvents containing bromine have the advantage of being non-flammable, including N-propyl bromide or 1-bromopropane, but cause environmental pollution when discharged to the outside, cause contact irritation to the human body, or cause serious diseases when inhaled for a long time. It has been found to cause Silicone oil is estimated to cause cancer according to the results of recent animal experiments, and regulations on its use have begun. The dry cleaning method using liquefied carbon dioxide requires expensive equipment as it liquefies carbon dioxide using a high pressure of 600 psi or more, and there is a risk of explosion. Wet cleaning involves shrinkage and deformation of fibers due to water. there was

Recently, a solvent represented by Formula 1 has been proposed for washing textiles, and it has been found that the solvent is safe for the human body and the environment, has excellent cleaning power against contamination, and has the advantage of being fast and easy to dry with low risk of explosion.

In the expression

R ₁ and R ₂ are each independently hydrogen or linear or branched chain alkyl having 1 to 4 carbon atoms;

R ₃ is hydrogen or straight or branched chain alkyl having 1 to 4 carbon atoms.

In the expression

R ₁ and R ₂ are each independently a straight-chain or branched-chain alkyl having 2 to 4 carbon atoms, and may be linked to each other to form cycloalkyl.

The solvent represented by Chemical Formula 1 was found to be suitable not only for dry cleaning but also for cleaning with water, because it is soluble in water, unlike petroleum-based, chlorine-based solvents, or solvents containing silicon oil. However, although the solvent of Chemical Formula 1 is relatively small compared to petroleum-based and chlorine-based solvents, there is still a limit to leaving a specific odor on fibers after washing.

In adding reference numerals to components of each drawing in this specification, it should be noted that the same components have the same numbers as much as possible, even if they are displayed on different drawings. In addition, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, the detailed description will be omitted.

Hereinafter, fiber refers to laundry to which the dry cleaning composition according to an embodiment of the present invention is applied, and includes clothing, miscellaneous goods, bedding, and other products including fibers.

Hereinafter, the composition for dry cleaning may be a composition for dry cleaning of fibers or may be a liquid composition.

The dry cleaning composition according to an embodiment of the present invention includes a solvent represented by Chemical Formula 1 and fragrance, and the fragrance may have a log P value of -1.0 to 4.5.

Hereinafter, the solvent means a compound represented by Formula 1 below or a mixture of the compounds.

[Formula 1]

In the expression

R ₁ and R ₂ are each independently hydrogen or linear or branched chain alkyl having 1 to 4 carbon atoms;

R ₃ is hydrogen or straight or branched chain alkyl having 1 to 4 carbon atoms.

In the above formula, R ₁ and R ₂ are each independently a straight-chain or branched-chain alkyl having 2 to 4 carbon atoms, and may be linked to each other to form a cycloalkyl.

Hereinafter, fragrance may refer to a dry cleaning composition used together with the solvent of the present invention and one or more compounds that emit scent from fibers washed using the dry cleaning composition.

Specifically, in the present invention, by using a fragrance with a log P value of -0.1 to 4.5, it is possible to reduce the specific smell of the solvent in the washed fabric by leaving the fragrance in the fabric, and the fragrance in the washed fabric Sustainability can be improved.

In addition, the fragrance having the above log P value remains in the washed fabric and can prevent the formation of wrinkles in the fabric. During the washing process of the fibers, a process of removing contaminants using mechanical force as well as contact with the composition for dry cleaning may be accompanied, and temporary deformation of the fibers may be induced during the process. Fibers may be composed of molecules containing hydrophilic functional groups on at least a part of their surface, although there is a difference depending on the type of material constituting the fibers, and the hydrophilic functional groups may be formed by contacting adjacent hydrophilic functional groups or water or hydrophilic molecules in the washing process. Intermolecular forces, including hydrogen bonds, can be induced between them. Such intermolecular attraction acts relatively strongly when the fiber is deformed, so that wrinkles can be formed according to the crumpling of the fiber. The fragrance according to the present invention maintains the surface of the fiber relatively lipophilic while remaining on the fiber by using the log P value as described above, thereby reducing the intermolecular force constituting the fiber to prevent wrinkle formation of the fiber. there is.

Hereinafter, P is a fractionation coefficient, which may represent the solubility of the compound in two solvents, but may specifically be an octanol-water fractionation coefficient. For example, P may be the ratio of the compound's solubility in octanol and the compound's solubility in water. If the compound is lipophilic, the P value can be very large, so it can be expressed as a log P value.

Fragrance may be an organic compound having a unique fragrance, but is not limited to aromatic, and a log P value of -0.1 to 4.5 may be used. When the log P value of the fragrance is lower than -1.0, the dry cleaning composition or the dry cleaning composition rapidly evaporates from the surface of the fabric washed with the composition, resulting in a rapid decrease in fragrance on the surface of the fiber. When the log P value of the fragrance is higher than 4.5, compatibility with the solvent of the present invention is rapidly lowered, resulting in separation of the fragrance and the solvent in the dry cleaning composition. That is, the fragrance used in the present invention may be one or more compounds that are soluble in octanol at a ratio of about 0.8 to 30,000 times that of water.

Preferably, fragrances having a log P value of 0.5 to 4.5 may be used, and more preferably, those having a log P value of 0.7 to 4.5 may be used. More preferably, the fragrance may use a log P value of 1.0 to 4.4, and most preferably, a log P value of 2.0 to 4.4 may be used for the fragrance. The solvent according to the present invention may have a log P value of approximately 1.07, and the log P value of the fragrance is similar to that of the solvent or relatively high compared to the solvent, and a level capable of maintaining compatibility with the solvent is used. It is possible to simultaneously provide excellent persistence on post fibers and excellent compatibility of the composition itself.

Solketal peculiarity dreadlocks Example 1 3.0 3.2 Example 2 2.7 3.7 Example 3 2.3 4.0 Example 4 2.2 4.2 Example 5 1.7 4.2 Example 6 1.5 4.3 Comparative Example 1 4.8 - Comparative Example 2 4.5 1.7 Comparative Example 3 4.5 1.9

When the dry cleaning composition according to the example was used, it was confirmed that as the log P value of the fragrance increased, the specific smell of Solketal in the fibers after washing was reduced, but the log P value was lower than -1.0 in Comparative Examples 2 and 4.5. In Comparative Example 3 exceeding , it was confirmed that the degree of specific odor reduction was rapidly reduced to a level similar to that of Comparative Example 1 that did not use a separate fragrance.

Likewise, as the log P value of the fragrance included in the dry cleaning composition according to the example increased, the fragrance of the fragrance in the fabric after washing became stronger, but when the fragrance according to Comparative Examples 2 and 3 was used, the fragrance was very weak. Confirmed.

This result seems to be because the more lipophilic the log P value of the fragrance used in the dry cleaning composition is, the more it is not washed out during the washing process and remains on the fiber, reducing the specific smell of Solketal or smelling its own fragrance. In Comparative Example 3, as the log P value of the fragrance was too large, it seems that a relatively large amount of solketal remained on the fiber surface as the solvent and fragrance were applied separately in the dry cleaning composition.

Experimental Example 2. Evaluation of wrinkle formation of fibers after washing

After washing the fibers using the dry cleaning compositions according to Examples and Comparative Examples according to the present invention and drying the fibers, the degree of wrinkle formation was sensory evaluated, and the results are shown in Table 3 below.

After washing, the degree of wrinkle formation of fibers was evaluated with a complex satisfaction based on visual and tactile sensations, and 15 textile evaluation monitoring agents were evaluated and the average was calculated (5 points: very satisfied, 4 points: satisfied, 3 points: Moderate, 2 points: dissatisfied, 1 point: very dissatisfied).

Satisfaction with wrinkles Example 1 3.7 Example 2 3.7 Example 3 3.9 Example 4 4.0 Example 5 4.3 Example 6 4.3 Comparative Example 1 2.3 Comparative Example 2 1.8 Comparative Example 3 2.7

When the dry cleaning composition according to the example was used, it was confirmed that as the log P value of the scent increased, the amount of wrinkles formed in the fibers after washing decreased, resulting in higher satisfaction. However, in Comparative Example 2 having a log P value lower than -1.0 and Comparative Example 3 having a log P value exceeding 4.5, it was confirmed that the amount of wrinkles rather increased.

This result seems to be because the more lipophilic the log P value of the fragrance used in the dry cleaning composition is, the more it remains on the surface of the fiber and reduces the intermolecular attraction of the surface of the fiber. In Comparative Example 3, as the log P value of the fragrance becomes too large, the solvent and fragrance are separated in the dry cleaning composition, making it difficult for the fragrance to remain. appears to be formed.
