Description

Solvent, solvent moisture removal system and laundry device

The present invention relates to a solvent used for dry cleaning, a water removal system of a solvent and a laundry apparatus.

In general, washing, which is a process of removing contamination of fibers or clothes, is classified into two types.

The first is to use a laundry detergent in the usual way. That is, it is a method of dispersing a surfactant in water and increasing the alkalinity of water to remove contamination, rinsing it, and then dehydrating and drying.

Second is dry cleaning. That is, the fiber may be deformed on the surface and inside of the fiber due to alkaline washing conditions, long-term contact with water, and the force of the washing machine that is strongly driven for a long time, causing loss of shine and deformation such as shrinkage or relaxation (for example, In the case of natural protein fibers such as wool or silk fabrics and artificial dogs or acetate fibers), petroleum based solvents (solvents), chlorine based glycol esters, cyclic silicones or silicone based terpene oil solvents such as fluorine and limonene are used. Oil solvents are dissolved and removed, and these solvents are physically removed from the garment, followed by drying to volatilize the solvent.

Here, the general method using a laundry detergent is excellent in removing water pollution due to the use of water in a large amount, but there is a limit to the removal of oil contamination, and the deformation on the surface and inside of the fiber due to alkaline washing conditions and long-term contact with water. It can cause a loss of shine and cause deformation such as shrinkage or relaxation. Thus, in recent years, neutral liquid detergents are commercially available to prevent clothing damage and deformation due to the basicity of the detergent, but they are also diluted with water, and there is still a disadvantage in that deformation by water cannot be alleviated.

On the other hand, dry cleaning can prevent damage or deformation of fibers and clothes, which is a disadvantage of water washing. However, dry cleaning shows excellent properties for oil contamination but has limitations for water pollution. In addition, in most cases, the laundry is to be carried out in a closed laundry system, which is classified as a substance harmful to the human body and the environment, and thus the equipment is expensive and has a very complicated disadvantage in maintaining the laundry system. In addition, in order to improve aqueous decontamination, dry cleaning includes a component, commonly referred to as "soap", in which various ionic surfactants such as anionic, nonionic, cationic and amphoteric are mixed with a very small amount of water in a dry cleaning solvent. The method of washing by adding very small amount is used. However, the dry cleaning solvent has a low affinity with water, which limits the amount of soap it can contain, and therefore it is still difficult to remove aqueous contamination.

On the other hand, looking at the characteristics of each solvent used for dry cleaning are as follows.

Perchlorethylene (PERC), trichloroethylene, and the like, which are most commonly used in dry cleaning, have the advantage of being nonflammable without damaging the fabric.

However, there is a problem that causes air pollution, is non-biodegradable, and particularly carcinogenic to the human body. Therefore, recently, hydrocarbons having a mixed form of petroleum-based straight chain, branched chain, cyclic or the like having about 5 to 13 carbon atoms have been used in place of chlorine-based solvents.

However, these hydrocarbon solvents present a risk of fire and explosion, cause environmental pollution (VOC (cause of ozone production)), and the solvents themselves have microbial contamination problems. In the case of Stoddard Solvent, a typical hydrocarbon type dry cleaning solvent, inhalation carcinogenicity has been confirmed. Thus, many studies have been conducted to develop safer and more environmentally friendly solvents for the human body in dry cleaning.

US Patent Nos. 7087094 (dipropylene glycol n-propyl ether) and 7144850 (dipropylene glycol dimethyl ether) disclose solvents in the form of ethylene glycol ethers. These glycol ether-based solvents are relatively safe for the human body and the environment, and have an advantage of containing a certain amount of water. However, there is a disadvantage in that a high volatility of the temperature requires a lot of energy and time to dry the fibers or clothing. In addition, U.S. Pat.Nos. 4,598,30,604 and 6063135 use cyclic silicone solvents as environmentally friendly dry cleaning solvents. However, cyclic silicones also have a problem of carcinogenicity, a very low affinity for water, and a very low oil pollution decontamination ability. As such, dry cleaning solvents are harmful to the human body and the environment and require a closed laundry system, and the use of these solvents is increasing due to the high risk of fire or explosion. In washing, conventional water washing or dry cleaning uses an excessive amount of water or a solvent.

Below, Table 1 shows the amount of wash water according to the capacity of the washing machine and the amount of washing. As can be seen from Table 1, in the case of a drum washing machine, a large amount of washing requires 28 to 48 liters of water depending on the capacity of the washing machine, and in the case of a general washing machine, a large amount of washing water of 78 to 117 liters is required. In the case of dry cleaning, there may be differences depending on the device capacity, but a solvent storage tank of about 200 liters is required. In addition, even in washing clothes, the solvent to be put into the dry cleaning washing tank takes tens of liters. Therefore, there is a need for a method for a system capable of washing clothes with a small amount of solvent more effectively in washing clothes using water or a solvent.

<Test method>

Oily water cleaning test

For the quantitative evaluation of decontamination, Japanese standard contaminated cloth (hereinafter referred to as contaminated cloth) (cotton, contaminated-oleic acid, triolein, oleic acid cholesterol, paraffin oil, etc.) was used. After measuring the initial chromaticity of each of the 8 x 5 cm x 5 cm cloths using a colorimeter, attach 8 dirt cloths to the white cotton tee.

After spraying 40 g to 100 g of acetone glycerol on the contaminated cotton tee in a drum washing machine, tumbling for 10 minutes in a standard course, deoiling at 1000 rpm, and then general general sun drying. After drying at room temperature (23-25 ° C.) and relative humidity (20-30 RH%) for 8 hours, the chromaticity is measured again using a colorimeter.

The change of the white balance (WB) value was made into the change of the washing power of oil-water contamination.

<Test result>

As shown in Figure 2, by spraying the solvent in a spray method was shown the result of the soil cleaning force according to the solvent content.

In Figure 2, it can be seen that the washing power is improved as the injection amount of acetone glycerol (Acetone glycerol) increases.

Figure 3 is a result of the soil cleaning power test for the method of applying the solvent to the contamination and the solvent contact time.

In the graph shown in (a) of FIG. 3, when the acetone glycerol solvent is supplied to the garment, it is poured randomly without spraying. Therefore, when the solvent is partially applied to the clothes, decontamination is not effective. In this case, even if the washing time is extended to the drying course, the washing power appears to be lower, which randomly pours the solvent into the clothing, so that the solvent-free portion of the clothing occurs, the washing power of the corresponding clothing is lowered. This can be seen in (a).

On the other hand, in the graph shown in (b) of Figure 3, acetone glycerol (Acetone glycerol) solvent of the same capacity as in Figure 3 (a) is evenly sprayed on the clothing through the solvent injection unit 120. Since the solvent is evenly applied to the clothes, regardless of the washing time, it can be seen through (b) of FIG.

Therefore, as can be seen in Figure 3, it was confirmed that the even coating of the solvent evenly to the clothes rather than simply increasing the washing time, the more important factor in effective washing.

4 is a cleaning force test result of the contaminated cloth corresponding to the time for deoiling the solvent.

Earlier, under the same conditions as the experiment, evenly sprayed acetone glycerol solvent, tumbling with a washing machine standard course for 10 minutes, at 1400 rpm, different deoiling time (2 minutes, 8 minutes) And, after drying at room temperature, color difference values were taken to show the white balance (WB) values before and after washing.

As can be seen in Figure 4, even if the solvent is sprayed in the same manner and the washing for the same time, it was found that the washing effect is increased by increasing the rotation speed of the washing tank in the desolvent process, increasing the desolvent time.

According to the experimental results shown in Figures 2 to 4, the solvent of formula (1) or formula (2), it can be confirmed that the clothes can be effectively washed even in the amount much less than the amount of washing water or dry cleaning solvent used in the conventional washing Can be.

In addition, evenly applying the solvent to the soiled portion of the clothing using the spray device, it was found that even better cleaning power by using the same volume of solvent than to pour the solvent to the clothes at random. In addition, when washing with a small amount of solvent, when the solvent is increased at a high speed to increase the centrifugal force, the solvent penetrates the clothes, and the effect of removing the contamination is increased, and the washing power is also enhanced.

Figure 5 is a block diagram showing the configuration of a preferred embodiment of a water removal system of a solvent and a washing apparatus including the same according to the second invention.

In one embodiment, referring to Figure 5, the water removal system 200, it is revealed in advance that it is applied to the washing apparatus for effectively dry cleaning the laundry by increasing the cleaning power of the dry cleaning solvent and ensuring the safety of use.

First, the dry cleaning solvent will be described.

The dry cleaning solvent used in the present invention simultaneously removes oil-soluble and water-based contamination, and is harmless to humans and has environmentally friendly properties. Such dry cleaning solvents have structures represented by the following Chemical Formulas 3 and 4.

Formula 4

<In Formula 4, R ₁ , R _{2 And} R ₃ Independently from each other hydrogen, normal alkyl having 1 to 24 carbon atoms, alkenyl having 2 to 24 carbon atoms, having 3 to 24 carbon atoms Isoalkyl, cycloalkyl having 4 to 24 carbon atoms, or acyl having 1 to 24 alkyl groups bonded to a carbonyl group, except where R ₁ , R ₂ and R ₃ are hydrogen at the same time.

Formula 5

In Formula 5, R ₄ and R ₅ are each independently a hydrogen atom or an alkyl having 1 to 4 carbon atoms, and R ₆ is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms or an alkyl atom having 1 to 4 carbon atoms. It represents the nil group>

The solvent having the structure of Chemical Formula 5 described above is mainly 4-butoxymethyl-2,2-dimethyl [1,3] prepared by synthesizing glycerol or a glycerol derivative with acetone, methyl ethyl ketone, methyl isobutyl ketone, and butylaldehyde. ] May correspond to a compound such as dioxalane, and preferably, may correspond to acetone-glycerol.

The dry cleaning solvent as used in the present invention has an oil-soluble pollution and an aqueous pollution effect, has a quick drying effect, and is safer for the human body and the environment than a conventional dry cleaning solvent.

Specifically, as shown in Tables 2 and 3 below, the dry cleaning solvent (example) used in the present invention contains much less moisture than Comparative Examples 1 to 6 itself, and Comparative Examples and In contrast, it can be confirmed that the stability at 4 ℃ for 4 weeks at high temperature without degradation over time conditions.

Here, Examples 1 and 2 shown in Tables 2 and 3 are compounds synthesized in the structure of Chemical Formula 4 by reacting glycerol with acetone and ketones, respectively. That is, in Formula 4, R ₃ is hydrogen, and R ₁ and R ₂ have a structure of an alkyl group derived from acetone and ketones.

Through Table 2 and Table 3, it can be seen that it is advantageous to include less moisture in the solvent itself to ensure the safety of the solvent.

However, when the dry cleaning solvents contain water during the washing process, the washing power of the solvent is lowered, and is hydrolyzed over time to decompose and form into acetone, ketones, aldehydes and the like containing glycerin and carbonyl groups. It is converted into harmful substances and deepens the deterioration of cleaning power.

Thus, properly removing the moisture contained in the dry cleaning solvent through the water removal unit is a necessary process for reusing the dry cleaning solvent.

As shown in FIG. 5, the laundry apparatus for performing dry cleaning includes a water removing unit A for removing moisture of the solvent including water after washing. The water removal unit (A) is connected to the washing tank and the inflow pipe (U1), receives the solvent after washing from the washing tank, and connected to the solvent storage unit and the outflow line (U2) to remove the solvent from the solvent to the solvent storage unit It has a configuration to supply.

Such a water removal unit (A) may be formed before and after the filter for cleaning the solvent after washing, it may be formed by adding as a form of the filter. That is, as described above, the water removal unit (A) is composed of a compound having excellent water binding force in the form of a filter, disposed on the solvent pipeline, or composed of a portion of the filter for purifying the solvent installed inside the washing machine do.

On the other hand, in addition to the reject water first (A) according to the present invention is a physical method, sodium sulfate (Na2SO _4), magnesium sulfate (MgSO _4), using the calcium sulfate (CaSO ₄₎ to remove water through a chemical method Can be. Salts prepared with sulfate ions have crystallized water, which increases the binding strength with water in the solvent and thus has a dehydration function.

In addition, activated alumina and silica gel such as molecular sieve may be used.

In consideration of the structure of the laundry machine, it is preferable to remove moisture by the above chemical method, rather than the physical method that requires a lot of equipment to remove the moisture.

Referring to FIG. 5, the water removal system 200 of the solvent includes a detection unit 210 for detecting a state of a replacement determination factor of the water removal unit A, and a control unit for generating replacement information of the water removal unit A ( And a display unit 230 for displaying replacement information.

The detection unit 210 is formed on the inlet pipe U1 or the outlet pipe U2 described above and serves to detect a state of the replacement determination factor of the water removing unit A.

Here, the replacement determination factor means a property that can measure the current water collection performance of the water removal unit A, and can use a change in the electrical conductivity of the solvent. That is, when the collection trapping capacity of the water removing unit A is lost, the water contained in the solvent is not removed, and the water content in the solvent increases, so that the components of the compound that make up the solvent are relatively reduced, so that the solvent vision Specfic conductance is different.

For example, among the solvents used in the present invention, in the case of acetone-glycerol, the electrical conductivity is lower than that of water, and as the content of water increases, the electrical conductivity becomes higher. Recognizing the change in the electrical conductivity of the solvent can generate information about the replacement time of the water removal unit (A).

Here, the method of measuring the electrical conductivity can be obtained by configuring the detection unit 210 to include two electrodes to flow a current through the solvent to measure the magnitude of the current.

Meanwhile, as illustrated in FIG. 5, the detector 210 may be divided into a front detector 211 and a rear detector 212 before and after the water removing unit A, respectively.

In determining the replacement time of the water removal unit A, it is possible to detect when the water removal unit A is no longer performing by comparing the electrical conductivity of the front detection unit 211 and the rear detection unit 212. have.

Next, the control unit 220 will be described.

The control unit 220 receives the state of the electrical conductivity detected by the above-described detection unit 210 serves to generate replacement information of the water removing unit A.

Here, the replacement information refers to information for effectively informing the user of the replacement time of the water removing unit A, and the corresponding replacement date or the remaining time until the replacement, or the immediate replacement message, the replacement date elapsed message, and the like. can do.

A DB is provided in which information about a state of electrical conductivity corresponding to a degree of cleaning power of the solvent having the structure of Formula 4 or Formula 5 or the solvent of Formula 4 and Formula 5 is pre-registered is provided. ) Is formed to be connectable thereto.

When a state of a predetermined replacement determination factor is input by the detection unit 210, the controller 220 generates replacement information by matching the information of the DB based thereon.

The control unit 220 may be implemented in one form of a control unit configured in the laundry machine.

Next, the display unit 230 will be described.

The display unit 230 serves to display the replacement information generated by the controller 220 so that the user can visually check. In order for the user to clearly know the replacement time of the water removing unit A, the replacement date may be directly displayed or the number of days remaining until the replacement date may be displayed according to the type of replacement information. Or an immediate replacement message or a replacement date message.

The display unit 230 may also be implemented in the display unit of the laundry machine.
