合成繊維基質に吸着させる。
（作用）
ナイロン繊維は、木綿繊維や他の合成繊維、例
えばビニロン繊維、ポリエステル繊維、アクリル
繊維とは水中での帯電特性を全く異にしている。
即ち、後者の繊維ではζ（ゼーター）電位が広い
PH範囲において陰性であるのに対して、ナイロン
繊維ではPH5.35に等電位点があり、このPH値より
アルカリ側ではζ電位が陰性、酸性側では陽性と
なる。
ナイロン繊維にカチオン性界面活性剤を吸着保

既に述べた通りである。本発明は、ナイロン繊維
に対して、アニオン活性剤を含有する油剤組成物
を吸着保持させる、即ち上記等電位点よりも酸性
側でナイロン繊維のζ電位を陽性に維持し、これ
にアニオン活性剤を含有する油剤組成物を作用さ

となる。また、この油溶性アニオン界面活性剤を
ノニオン系界面活性剤と組合せて使用することも
重要であり、前記アニオン系界面活性剤単独では
吸着処理用エマルジヨンが安定しにくく、その結
果としてムラ吸着等が生じ易いが、ノニオン系界
面活性剤を併用することにより、この欠点も解消

(Industrial Application Field) The present invention relates to a method for manufacturing dust control products such as dust control products, such as dust control products, which can be cleaned or removed in a dry state, and more specifically, has dust adsorption properties and dust retention properties. The present invention relates to a method for producing a dust control product made of oil-treated nylon synthetic fibers, which has significantly improved restaining properties while maintaining an excellent level of recontamination. (Prior art) In recent years, so-called chemical cleaning tools or dry maintenance cleaning tools have been widely used as cleaning tools that can be cleaned without getting hands wet.This type of material is used in various fields such as cleaning motu, duster, dust removal mat, etc. It has come to be widely used. Such dust control products are produced by emulsifying a self-emulsifying and self-exhausting oil composition containing an oil agent and a surfactant having a cationic active group in water, and immersing fibers in this aqueous emulsion. It can be obtained by adsorbing and retaining the oil composition on. 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) Oil impregnation treatment has been successful for cellulose fibers such as cotton fibers, but when applying this to synthetic fibers, especially nylon fibers, oil adsorption treatment and use are necessary. It is recognized that this poses a serious problem when it comes to laundering finished 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, an object of the present invention is to provide a synthetic fiber-based dust control product that smoothly and efficiently adsorbs oil agents onto synthetic fibers, particularly nylon fibers, and has excellent dust retention and recontamination prevention performance. . (Means for Solving the Problems) According to the present invention, mineral oil or synthetic lubricating oil;
An oil composition containing 0.1 to 3% by weight of an oil-soluble anionic surfactant and 0.1 to 5% by weight of a nonionic surfactant per oil composition is dispersed in water to form a self-emulsifying and self-exhausting water composition. An oil emulsion is formed, and this emulsion and a nylon synthetic fiber matrix are brought into contact at a pH of 5.35 or less, and the oil composition in the emulsion is adsorbed onto the nylon synthetic fiber matrix. (Function) Nylon fibers have completely different charging characteristics in water from cotton fibers and other synthetic fibers, such as vinylon fibers, polyester fibers, and acrylic fibers.
That is, in the latter fiber, the ζ (zeta) potential is wide.
While it is negative in the PH range, nylon fiber has an equipotential point at PH5.35, and the ζ potential is negative on the alkaline side of this PH value and positive on the acidic side. As already mentioned, when a cationic surfactant is adsorbed and retained on nylon fibers, recontamination occurs significantly. The present invention allows an oil composition containing an anionic activator to be adsorbed and retained on nylon fibers, that is, maintains the ζ potential of the nylon fibers positive on the acidic side of the above-mentioned equipotential point, and then adds an anionic activator to the nylon fibers. By applying an oil composition containing the above, the recontamination tendency of oil-impregnated nylon fibers is eliminated, and a dust control product with excellent dust retention and migration resistance is provided while imparting excellent adsorption and retention properties. It is. It is also extremely important that the anionic surfactant used in the present invention is oil-soluble. That is, by using an oil-soluble surfactant, the surfactant dissolves into the emulsion particles made of the oil agent, making it possible to effectively maintain the emulsion particles in a negative state. It is also important to use this oil-soluble anionic surfactant in combination with a nonionic surfactant, as the emulsion for adsorption treatment is difficult to stabilize if the anionic surfactant is used alone, resulting in uneven adsorption, etc. Although this is likely to occur, this drawback can also be overcome by using a nonionic surfactant in combination. (Operations and Effects of the Invention) According to the present invention, it is possible to provide a nylon-based oil-impregnated dust control product with excellent re-staining resistance by adsorbing and retaining an oil agent containing an anionic surfactant on nylon fibers. became possible. In addition, since it has become possible to adsorb a relatively large amount of oil to nylon fibers, it has become possible to improve dust adsorption and dust retention, and the oil can be evenly and firmly adsorbed by chemical adsorption. Therefore, troubles such as the oil agent transferring to the wiping surface are effectively prevented. Furthermore, since it is based on nylon fiber,
The abrasion resistance, strength, etc. of the fibers are improved, making it possible to extend the service life of dust control products, and by making it possible to use crimped fibers, the texture can also be improved. (Description of Preferred Embodiments of the Invention) The oil composition used in the present invention contains an oil agent, an oil-soluble anionic surfactant, and a nonionic surfactant as essential components. As the oil agent, any mineral oil and/or synthetic lubricating oil conventionally used in this type of oil-impregnating treatment can be used. As the mineral oil, any paraffinic, naphthenic, aromatic hydrocarbon, or a mixture thereof can be used, and specifically,
Liquid paraffin, spindle oil, machine oil, refrigeration oil, and other petroleum-based lubricating oils are used. As the synthetic lubricating oil, polyolefin oil (α-olefin oil), polyglycol oil, polybenzene oil, alkylbenzene oil, and other synthetic lubricating oils can be used. These oils can be used alone or in combination of two or more. 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 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, sequestering agents, flame retardants, flame retardants, and the like. Examples of nylon-based synthetic substrates include 6-nylon,
6,6-Nylon and other nylon fibers alone, as well as cellulose fibers such as cotton, mercerized cotton, and regenerated cellulose fibers, and other synthetic fibers such as polyvinyl alcohol fibers, acrylic fibers, and polyester fibers. A combination of yarns or strings such as motupu, woven fabrics such as wiping cloth, etc. are used.
It may be of knitted or non-woven fabric, or of tufted fabric such as dusting mat. 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 emulsion particle size is generally preferred to be from 0.1 to 50 μm. Oil impregnation treatment is performed by bringing this oil-in-water emulsion into contact with nylon synthetic fibers. Generally, it is desirable to immerse the fibers in the emulsion to cause the emulsion particles to self-exhaust. During oil impregnation treatment, the pH of the system is adjusted to a pH such that the ζ potential of the nylon fiber is positive, generally 5.4 or less, especially a pH of 3 to 5.
For this purpose, it is preferable to pre-treat the treated fibers with an acetic acid aqueous solution to achieve the above pH. There are no particular restrictions on the temperature during processing, but
Generally, it is desirable to set the temperature to 20 to 50℃,
The appropriate treatment time is in the range of 10 to 20 minutes. 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 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. During this dehydration treatment, it is a remarkable feature that the adsorbed oil agent is not substantially desorbed by re-emulsification, even though the present invention is highly dehydrated. 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. 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. (Example) Example 1 An oil composition having the following formulation was prepared. Liquid paraffin 96.8 parts by weight Sodium di-2-ethylhexyl sulfosuccinate
