Description
（産業上の利用分野）
本発明は、清掃用含油繊維の製造方法に関する
もので、より詳細には、油剤成分の水性乳化液か
ら、油剤の繊維への吸着処理を塩析作用により行
なう方法に関する。
（従来の技術）
近年、手を濡らさずに清掃が可能な清掃用具と
して、所謂化学ゾウキン或いはドライメンテンナ
ス・ゾウキンが広く使用されており、この種の材
料は各種清掃モツプ、ハタキ、防塵マツト等の分
野に広く使用されるに至つている。
このようなダストコントロール製品は、油剤及
びカチオン活性基を有する界面活性剤を含有する
自己乳化性及び自己吸尽性の油剤組成物を水中に
乳化させて、正に帯電した油剤微粒子を形成さ
せ、繊維が水中で負に帯電する性質を利用して、
繊維に油剤組成物を吸着保持させることにより得
られる。
ダストコントロール製品は、一般にレンタル制
で需要者に供給される。即ち、この製品は一定期
間にわたつて需要者に貸与され、清掃等に用いて
汚れた製品は、洗濯及び含油処理によつて再生さ
れ、再び需要者に供給され、その反復使用回数を
可及的に増加させることがコスト低減の上で重要
である。
（発明が解決しようとする問題点）
上述した含油処理は、木綿繊維等のセルロース
系繊維には成功しているが、これを耐摩耗性、強
度等に優れた合成繊維、特にナイロン繊維に適用
する場合には、油剤の吸着処理及び使用済み製品
の洗濯に関して重大な問題を生じることが認めら
れる。
即ち、セルロース繊維を油剤組成物の水性エマ
ルジヨンに浸漬した場合、数分の処理により液が
透明化し、油剤の吸着が完了し、またセルロース
繊維に対する油剤吸着量は50重量％迄のような高
いレベルに到達するが、ナイロン繊維を上記エマ
ルジヨンに浸漬した場合には、液は白濁した状態
で残存し、油剤吸着量も高々５重量％に達するに
すぎないのである。
また、ナイロン繊維に対してカチオン界面活性
剤を含む油剤組成物を吸着処理させると、汚れを
再吸着することによる繊維類の再汚染が著しいた
め、含油繊維をレンタル向けのダストコントロー
ル製品の用途に供給することが困難である。
従つて、本発明は、ナイロン類等の合成繊維を
含めた広範囲の繊維に対して容易にしかも手軽に
適用でき、繊維類に比較的多量の油剤を効率良く
且つ均一に吸着保持させ得ると共に、再汚染防止
性とダスト保持率とに優れた清掃用含油繊維の製
造方法を提供することを課題とする。
（問題点を解決するための手段）
本発明によれば、鉱物油または合成潤滑油と油
剤当り0.2乃至10重量％の非カチオン系界面活性
剤とを水中に分散させてダスト吸着用油剤の水性
乳化液を調製し、この水性乳化液と清掃用繊維と
を接触させ、清掃用繊維と水性乳化液とが十分な
じませた後、水性乳化液中に乳化液当り0.01乃至
５重量％の塩析剤を添加し、これにより乳化液中
のダスト吸着用油剤を清掃用繊維に吸着させる。
塩析剤としては、任意の水溶性無機塩が使用さ
れるが、アルカリ土類金属、特に塩化物を用いる
のが望ましい。

(Industrial Application Field) The present invention relates to a method for manufacturing oil-impregnated fibers for cleaning, and more particularly, to a method for adsorbing an oil agent onto fibers from an aqueous emulsion of oil components by salting out. . (Prior Art) In recent years, so-called chemical cleaners or dry maintenance cleaners have been widely used as cleaning tools that can be cleaned without getting hands wet, and this type of material is used in various cleaning motsupu, dust removal mats, dustproof mats, etc. It has come to be widely used in the field of Such dust control products emulsify a self-emulsifying and self-exhausting oil composition containing an oil agent and a surfactant with a cationic active group in water to form positively charged oil particles. Utilizing the property of being negatively charged in water,
It is obtained by adsorbing and holding an oil composition on fibers. Dust control products are generally supplied to customers on a rental basis. In other words, this product is lent to a user for a certain period of time, and if the product becomes dirty after being used for cleaning, it is recycled through washing and oil treatment, and then supplied to the user again, allowing the product to be used repeatedly as many times as possible. In order to reduce costs, it is important to increase the (Problems to be Solved by the Invention) The oil impregnation treatment described above has been successful for cellulose fibers such as cotton fibers, but it is difficult to apply this to synthetic fibers that have excellent abrasion resistance and strength, especially nylon fibers. In this case, it is recognized that serious problems arise regarding the adsorption treatment of oil agents and the washing of used products. That is, when cellulose fibers are immersed in an aqueous emulsion of an oil composition, the liquid becomes transparent after a few minutes of treatment, and the oil adsorption is completed, and the amount of oil adsorption on the cellulose fibers reaches a high level of up to 50% by weight. However, when nylon fibers are immersed in the emulsion, the liquid remains cloudy and the amount of oil adsorbed is only 5% by weight at most. In addition, when nylon fibers are adsorbed with an oil composition containing a cationic surfactant, the fibers are significantly re-contaminated due to re-adsorption of dirt, so oil-impregnated fibers are supplied for use in dust control products for rentals. difficult to do. Therefore, the present invention can be easily and conveniently applied to a wide range of fibers including synthetic fibers such as nylons, and can efficiently and uniformly adsorb and retain a relatively large amount of oil on the fibers. An object of the present invention is to provide a method for producing oil-impregnated cleaning fibers with excellent recontamination prevention properties and dust retention. (Means for Solving the Problems) According to the present invention, mineral oil or synthetic lubricating oil and a non-cationic surfactant of 0.2 to 10% by weight per oil agent are dispersed in water to form an aqueous dust adsorption oil agent. After preparing an emulsion, bringing the aqueous emulsion into contact with the cleaning fibers, and allowing the cleaning fibers and the aqueous emulsion to fully blend together, salting out 0.01 to 5% by weight based on the emulsion is added to the aqueous emulsion. A cleaning agent is added thereto, thereby causing the dust-adsorbing oil agent in the emulsion to be adsorbed onto the cleaning fibers. As the salting-out agent, any water-soluble inorganic salt can be used, but alkaline earth metals, especially chlorides, are preferably used. (Function) In the oil impregnation treatment method of the present invention, in a system where an aqueous emulsion of an oil agent for dust adsorption and fibers coexist, when a salting-out agent is added to this system, the emulsified state of the oil agent is destroyed, and the oil agent is applied to the fibers. This is based on the knowledge that the adsorption of ions occurs selectively and uniformly. Moreover, according to the treatment method of the present invention, it is also advantageous that the oil agent can be efficiently adsorbed onto the fibers even when the amount of salting-out agent added per aqueous emulsion is as low as 1% by weight or less. It is one of the. Adsorption treatment of oil agent from aqueous emulsion to fiber is
It is possible to maintain the dispersed oil particles as small as possible in particle size and to adsorb them onto the fibers while maintaining this emulsified state.
It was thought to be advantageous in preventing uneven adsorption and ensuring uniform adsorption to the entire fiber. However,
In the present invention, by adding a salting-out agent to the system to destroy the emulsified state, it is possible to achieve more uniform and efficient oil adsorption, and this fact can be seen in the example described below. It will become clear by reference. Furthermore, according to the present invention, any surfactant can be used as a surfactant for emulsifying oil agents, without being limited to cationic surfactants and amphoteric surfactants containing cationic active groups. Then,
The room for choice will be expanded, and problems such as re-contamination that have arisen with the use of conventional cationic surfactants will also be resolved. (Operations and Effects of the Invention) According to the present invention, there is provided a method for producing oil-impregnated fibers whose principle is completely different from that of conventional adsorption treatment methods.
In particular, it has become possible to efficiently adsorb and retain a sufficient amount of oil for dust adsorption even on synthetic fibers such as nylon. In addition, it is now possible to use any surfactant, which improves recontamination prevention ability, prevents uneven adsorption, and enables uniform adsorption to prevent oil from migrating to the cleaning surface. , the dust rate could be improved. Furthermore,
For this purpose, it has become possible to use synthetic fibers with excellent wear resistance and strength, making it possible to extend the lifespan of rental products. (Description of Preferred Embodiments of the Invention) In the present invention, an aqueous emulsion is obtained by emulsifying and dispersing a dust-adsorbing oil agent by the action of a surfactant. As the oil agent, any mineral oil and/or synthetic lubricating oil conventionally used in this type of oil impregnation treatment can be used. As the mineral oil, any paraffinic oil, naphthenic oil, aromatic hydrocarbon oil, or a mixture thereof can be used. Specifically, liquid paraffin oil, spindle oil, machine oil,
Refrigerating machine oil and other petroleum-based lubricants are used. As synthetic lubricating oil, polyolefin oil (α
-olefin oils), polyglycol oils, polybutene oils, alkylbenzene oils, and other synthetic lubricating oils. These oils can be used alone or in combination.
Combinations of more than one species can also be used. As the surfactant, a non-cationic surfactant, a nonionic surfactant, an anionic surfactant, or a combination thereof is used. Alternatively, any amphoteric surfactant may be used without particular limitation as long as emulsion type performance is obtained. Of course, it is also possible to use a combination of two or more surfactants. Suitable examples of surfactants include, but are not limited to: Nonionic surfactants Polyoxyethylene alkyl ether, polyoxyethylene alkylaryl ether, polyethylene glycol fatty acid ester, polyoxyethylene fatty acid ester, polyoxyethylene fatty amine ether, polyoxyethylene fatty amide ether, polyhydric alcohol fatty acid ester, oxyethylene polyhydric alcohol fatty acid ester,
Alkylolamide, pluronic type activator. Anionic surfactant Sodium dialkyl sulfosuccinate, alkyl sulfonate, fatty acid-amino acid condensate, funnel oil, higher alcohol sulfate ester salt, alkylbenzene sulfonate, alkyl sulfate ester salt, alkylolamide sulfate ester, alkylnaphthalene sulfonic acid salts, fatty acid ester sulfonates, fatty acid amide sulfonates, heterocyclic sulfonates, fatty acid salts. In the present invention, the surfactant is 0.2
It is advantageous to use amounts of from 1 to 10% by weight, especially from 1 to 3% by weight. As the surfactant, it is particularly desirable to use a combination of an oil-soluble anionic surfactant and a nonionic surfactant from the viewpoint of preventing recontamination. As the oil-soluble anionic surfactant, any oil-soluble surfactant having an anionic active group such as a carboxylate or a sulfonate can be used. The most preferred example is sodium dialkylsulfosuccinate such as sodium di-2-ethylhexylsulfosuccinate, and petroleum sulfonates and higher fatty acid alkaline earth metal salts such as calcium stearate and magnesium stearate may also be used. As a nonionic surfactant, HLB is 5 to 5.
Nonionic surfactants in the range of 13, especially in the range of 6 to 11, such as polyoxyethylene alkyl phenyl ethers, especially those with an added mole of ethylene oxide of 2 to 6, polyoxyethylene alkyl ethers, especially those with an added mole of ethylene oxide Those with an additional mole number of 2 to 6 are preferably used. The oil-soluble anionic surfactant is preferably used in an amount of 0.1 to 3% by weight, especially 0.3 to 1% by weight per oil agent, and the nonionic surfactant is preferably used in an amount of 0.3 to 1% by weight per oil agent.
It is preferred to use amounts of 0.1 to 5% by weight, especially 0.5 to 2% by weight. Of course, any known ingredients can be added to the oil composition used in the present invention according to known formulations. For example, the oil composition may contain one or more of antibacterial agents, antifungal agents, colorants, fragrances, sequestrants, flame retardants, flame retardants, various stabilizers, and the like. Fibers include nylon fibers such as 6-nylon and 6,6-nylon; acrylic fibers; synthetic fibers such as polyester fibers, polyvinyl alcohol fibers, and vinyl chloride fibers; cellulose fibers such as cotton, mercerized cotton, and polynosic fibers; and wool. or blended fibers consisting of two or more of these animal fibers. The present invention focuses on synthetic fibers that are difficult to adsorb and retain large amounts of oil with conventional oil-impregnating treatments.
Especially those made of nylon fibers or acrylic fibers alone, or those made of 20% by weight of these synthetic fibers per total fiber.
The above can be advantageously applied particularly to those containing 50% by weight or more. The nylon fibers and acrylic fibers mentioned above can be highly crimped or bulk processed, and by applying oil impregnation to these fibers, the dust rate can be significantly improved compared to that of cotton fibers. Moreover, the texture can also be improved. These fibers can take any form such as various spun yarns and multifilaments. These may be of twisted yarn or string, such as mops, of woven, knitted or non-woven fabrics, such as wiping cloth, or of tufted fabrics, such as dusting mats. When impregnating fibers with oil, the aforementioned oil composition is made into an oil-in-water emulsion. The concentration of the oil composition in water is generally 0.01 to 10% by weight, particularly 0.5%.
A range of from 5% to 5% by weight is preferred, and the size of the emulsion particles is generally from 0.1 to 50 μm. The treatment of fibers with an emulsion of the oil composition can be carried out either batchwise or continuously.
This treatment is most easily carried out by dipping the fibers in the emulsion described above, but the treatment can also be carried out by spraying the fibers with the emulsion. Further, when the fibers are continuously treated with the oil emulsion, the oil emulsion and the fibers may be brought into contact with each other in a countercurrent or cocurrent manner. The conditions for bringing the oil emulsion into contact with the fibers are not particularly limited and can be varied over a wide range, but generally a PH range of 3 to 10 is desirable for uniform and efficient adsorption treatment. In the present invention, a salting-out agent is added to the system while the oil emulsion and fibers are in contact with each other. Any water-soluble inorganic salt can be used as the salting-out agent. Salting-out agents include ammonium salts such as ammonium sulfate and ammonium chloride; alkali metal salts such as sulfate, potassium sulfate, sodium chloride, potassium chloride, and sodium nitrate; calcium chloride, barium chloride, magnesium chloride, magnesium sulfate, and calcium nitrate. , alkaline earth metal salts such as strontium chloride; metal salts of group b of the periodic table such as zinc chloride and zinc sulfate; metal salts of group b of the periodic table such as aluminum sulfate, aluminum chloride, and basic aluminum chloride; sulfuric acid Examples include group metals of the periodic table such as ferrous iron and ferrous chloride, or combinations or double salts of two or more thereof. According to Hardy's law, colloidal solutions coagulate due to oppositely charged ions, and the effect is said to be greater as the ion valence increases. In other words, Ca 2+ is higher than Na + , A1 3+ is higher than Ca 2+ , etc. For example, A S2S3 sol has a negative charge, but the valence, valence, and
The minimum concentration of valent metal ions (referred to as aggregation value) is as shown in Table 1.

Alkaline earth metal salts, especially chlorides, are effective since the resulting fibers tend to be recontaminated. The amount of salting-out agent added varies depending on the type of salting-out agent and the type of fiber, but in general, the amount added per oil emulsion is
It is preferably added in an amount of 0.01 to 5% by weight, particularly 0.05 to 1.0% by weight. When the amount is less than the above range, the effect of salting out to promote oil agent adsorption is small, and as the amount of the salting out agent increases, the adsorption rate increases, but there is no particular advantage when it exceeds the above range. It is best to add the salting-out agent in the form of an aqueous solution, and it may be added at the beginning of the contact between the aqueous emulsion and the fibers, but generally the aqueous emulsion and the fibers are mixed for 10 seconds to 10 minutes. It is preferable to add the salting-out agent after thoroughly contacting and blending the mixture for several minutes.
At this time, the temperature of the treatment bath is generally room temperature, but it is also suitable to heat the treatment bath to about 20 to 50° C. in order to efficiently adsorb the oil agent.
The treatment time after addition of the salting-out agent is generally 1 to 20 minutes. In the present invention, the adsorption amount of the oil composition to the fibers is generally 5 to 40% by weight, particularly
A range of 10 to 30% by weight is suitable. The fibers that have been impregnated with the oil agent are then subjected to dehydration treatment until the absorbed moisture contained in the fibers is 70% by weight or less, particularly 60% by weight or less. A remarkable feature of this dehydration treatment is that, despite the high degree of dehydration according to the present invention, the adsorbed oil agent is not substantially desorbed by re-emulsification. The dehydration treatment can be easily carried out using a dehydrator known per se, for example, a centrifugal dehydrator, a pressure dehydrator such as a pressure roll, a vacuum dehydrator, or the like. The dehydrated oil-impregnated fibers are then dried at a temperature of 60 to 80°C to form the final product. (Example) Various tests in the following examples were conducted as follows. (i) Dust test Put the sample (weight W F ) into a bottle, add fine silica sand powder twice the weight of the sample and 5 rubber balls, and stir for 1 minute. Then, remove the sample onto a wire mesh and leave it for 10 minutes. In a dust tester
Shake both sides 100 times and weigh (weight W D ). The dust ratio (D) was calculated from the following formula as the average value of three samples each. D=W D −W F /W F ×100 (ii) Cleaning test The sample was left overnight, and excess dust was adsorbed by massaging and pressing the sample. Washing was performed for 15 minutes using a household washing machine under the following conditions, and after drying, the reflectance of the sample was measured to determine the washing efficiency. Here, the cleaning efficiency is expressed by the following formula. Cleaning efficiency (%) = R W - R S / R O - R S × 100 R S : Y value before washing, R W : Y value after washing, R O : Y value of white cloth. (iii) Contamination test The sample was contaminated for 30 minutes using a targotometer (100 rpm) at 60°C and 10 g of dust.
The reflectance was measured and the contamination rate was calculated using the following formula. Contamination rate = R S - R W / R S ×100 R S : Y value before contamination, R W : Y value after contamination. Example 1 An oil composition (hereinafter referred to as oil agent A) having the following formulation was prepared. Mineral oil 99.8-94.0% Sodium di2-ethylhexyl sulfosuccinate
0.1-2% Polyoxyethylene nonyl phenol ether (4 moles of EO added) 0.1-4% HLB = 8.9 A crimped nylon fiber cloth is treated with an acetic acid aqueous solution, and then brought into contact with an aqueous emulsion of the above oil composition. An aqueous emulsion of a salting-out agent shown in Table 2 was added, and oiling treatment was performed under the following conditions. Bath temperature 30℃ PH 7 Bath ratio 1:25 Amount of oil agent 10% by weight per fiber Amount of salting-out agent 300ppm per emulsion Observe the state of the liquid 5 minutes, 10 minutes, and 15 minutes after adding the salting-out agent, and check the oil agent. The progress of adsorption was evaluated in the following three stages. ○ The liquid becomes completely transparent, and the oil agent has migrated from the bath into the fibers. △ The liquid has become opaque and most of the oil has migrated from the bath into the fibers, but a small amount of oil still remains in the bath. × The liquid is still a cloudy emulsion. The results are shown in Table 2. In addition, the dust rate and recontamination rate were measured for the sample oiled for 15 minutes, and the obtained results are also shown in Table 2. From the results in Table 2, it can be seen that by adding the salting-out agent, the oil agent is efficiently adsorbed and retained on the fibers within a short period of time. In addition, it can be seen that the use of alkaline earth metal salts brings about good results in terms of preventing recontamination.
