The present invention relates to a dust control product comprising a cleaning fiber substrate such as a mop, mat, or wiping cloth, and an oil composition adsorbed and retained in the fiber substrate. This product relates to dust control products with improved cleaning properties such as oil migration resistance and oily feel. Conventionally, cleaning fiber substrates impregnated with mineral oil or synthetic lubricating oil have been used to clean floors, walls, furniture,
It is widely used as a cleaning material, ie, a dust control product, to remove dust deposited or attached to bookshelves, etc., without scattering it. These oil-impregnated fibers for cleaning firmly adsorb and hold dust on the fiber surface without scattering it to the surroundings during cleaning work, and they also prevent the oil film that is caused by the migration of the oil contained therein into the surface to be cleaned. After a certain period of use, the used oil-impregnated cleaning fibers must be washed to remove contaminants and re-impregnated to prevent repeated use. Normal. Furthermore, in the case of a wiping cloth, since wiping is performed manually, it is required that it not give an oily feel. In general, the amount of oil impregnated into cleaning oil-impregnated fibers is 10 to 40% by weight per fiber in order to maintain the above-mentioned cleaning properties such as dust adsorption, dust retention, connectivity, and oil migration resistance. In order to impregnate such a large amount of oil, cotton fibers are exclusively used as the fiber material for dust control products. When cotton fibers are impregnated with an oil agent, their unique structure allows them to adsorb and retain the impregnated oil agent well, preventing the oil agent from transferring to the cleaning surface during cleaning and preventing rapid consumption of the oil agent due to this. Cotton fibers have the advantage of improving cleaning efficiency due to their ability to absorb and retain moisture, and these characteristics of cotton fibers have not been found in any other synthetic fibers. However, in conventional dust control products that use cotton fibers as a cleaning fiber matrix, when subjected to repeated use, the cotton fibers themselves become hard.
The disadvantage is that the texture is lost. In addition, it gives an oily feel and is not sufficiently durable. The present inventors used water-absorbent acrylic fibers with a water absorption of 20 to 60% as a cleaning fiber substrate instead of cotton fibers, and impregnated this with an oil agent to make a dust control product. The drawbacks of dust control products using fibers have been improved, and a dust control product with excellent cleaning properties such as dust adsorption, dust retention and durability, and oil migration resistance, and without an oily feel can be obtained. It has also been found that in the manufacturing process, the dehydration and drying steps can be performed more quickly and at lower energy costs. That is, the purpose of the present invention is to significantly prevent the transfer of oil to the surface to be cleaned during cleaning, and to achieve excellent cleaning properties such as dust adsorption, dust retention, and durability, and to remove oil when touched by hand. Our goal is to provide dust control products that do not give sexual sensations. Another object of the invention is that by using synthetic fibers in the cleaning fiber matrix instead of traditional cotton fibers,
To provide a dust control product that is lightweight in itself, does not lose its texture even after repeated use, and has excellent durability. Still another object of the present invention is to provide a dust control product that can be dehydrated and dried more quickly and at lower energy costs during its manufacture and regeneration. That is, according to the present invention, in a dust control product comprising a cleaning fiber substrate and a dust adsorption oil agent adsorbed and retained on the fiber substrate, the cleaning fiber substrate has a water absorption of 20 to 60% (DIN53814).
10 per total fiber weight
A dust control product with improved oily feel and oil migration property, characterized in that the fiber matrix is impregnated with 10 to 40% by weight of an oil agent for dust adsorption. is provided. The water-absorbing acrylic fiber used in the present invention is
It has an exceptionally high water absorption rate of 20 to 60% compared to ordinary synthetic fibers, as determined by the DIN53814 measurement method. As shown in the electron micrographs in Figures 1 and 2, this water-absorbing acrylic fiber has many pores inside the single fiber, and many of these pores are located on the outer surface of the fiber. The fibers have open pores, and many wrinkles or pleats are formed on the fiber surface in connection with this fine structure. The pore content or specific surface area of this fiber is determined by the water absorption rate mentioned above, and the fact is that it has a water absorption rate of 20 to 60%, whereas the water absorption rate of ordinary acrylic fibers is at most a few percent. This indicates the fact that this fiber can hold a large amount of dust-adsorbing oil. In other words, this water-absorbing acrylic fiber adsorbs and retains a large amount of oil in the pores within the fiber, so it has excellent dust adsorption and dust retention properties through this oil, especially when used repeatedly over a long period of time. Even when the cleaning is repeated, the oil agent is constantly supplied to the effective surface of the fibers due to capillary action, resulting in stable cleaning continuity. Furthermore, this porous fiber containing an oil agent achieves the unexpected advantage that the amount of oil agent transferred to the wiping surface is extremely small compared to conventional dust control products. That is, when oil-impregnated fibers are used for cleaning, if they migrate to the wiped surface, (a) if the surface to be cleaned is a paint film, there will be an adverse effect from the oil on the paint film; (b) the surface to be cleaned (c) The oil that has transferred to the surface to be cleaned will absorb dust, etc., causing problems such as even more staining, and the cleaning oil-impregnated fibers will become contaminated. It is no exaggeration to say that the most important issue is how to minimize the transfer of oil to the surface to be cleaned. However, in products in which cotton fibers are impregnated with an oil agent, a large proportion of the oil agent is retained on the fiber surface, so it is difficult to suppress the amount of oil agent transfer below a certain level. In contrast, according to the present invention, most of the oil is retained in the internal pores of the acrylic fibers, so the amount of oil transferred can be suppressed to an order of magnitude lower. This is a significant advantage of the present invention. In addition to the characteristic of a small amount of oil transfer, the product according to the present invention has a characteristic in terms of texture that there is little to no oily feel when touched. Generally, when fibers are moistened with water and then dried to examine the relationship between moisture content and damp feel,
In contrast to ordinary acrylic fibers, which do not lose their wet feel unless the water content drops below 5%,
In the case of the water-absorbing acrylic fiber used in the present invention, the wet feeling is already lost when the moisture content is 35% or less. This fact applies exactly in the case where the fibers are impregnated with an oil agent. This is probably because the solvent is stably held within the pores of the fibers. Moreover, in addition to the above-mentioned porous structure, this water-absorbing acrylic fiber has the characteristics of acrylic fiber itself, such as strength, durability, water resistance, lightness, stiffness, and dimensional stability. It has excellent properties. Furthermore, it can be manufactured using the same method as conventional products for oil impregnation treatment, and due to the structure of the acrylic fiber used, it has good water release properties, making dehydration and drying quick and easy, and at low energy costs. It has various advantages in that it can be carried out in This water-absorbing acrylic fiber is, for example,
As described in No. 103527 and No. 52-107326, a certain additive substance is added to the spinning stock solution of an acrylonitrile polymer and dry spinning or wet spinning is performed, and the additive substance is eluted into the spinning bath.
Alternatively, it can be produced by removing it from the spun yarn using an appropriate means. Suitable water-absorbing acrylic fibers are commercially available from Bayer AG under the trade name Dounova. This water-absorbing acrylic fiber, so-called staple fiber, can be used in the form of a filament to form a fiber substrate for cleaning. It can be knitted into a hataki, and made into a mat by tufting or electrostatic flocking onto a base fabric. Of course, this fiber may be crimped by means known per se. In the present invention, the above-mentioned water absorbent acrylic fibers having a water absorbency of 20 to 60% are used per total fiber weight.
One or more types of other fibers, such as natural fibers such as cotton, recycled fibers such as rayon, polyvinyl alcohol fibers, ordinary acrylic fibers, nylon fibers, etc., in an amount of 10% by weight or more, especially 20% by weight or more. It is used in combination with, but of course, it can also be used alone. If the amount of the water-absorbing acrylic fiber is less than the above-mentioned range, desirable cleaning properties such as dust collection, dust retention, and oil transferability will not be obtained, and the oily feel will not be improved. The above-mentioned mixing of the fibers is carried out by means such as blending, doubling, interweaving, and interweaving.
From the standpoint of reducing the strength and durability of the cleaning fiber matrix, as well as its cost, it is desirable that non-water-absorbing acrylic fibers be present in the fiber matrix in an amount of 20% by weight or more. Further, in the present invention, it is desirable to impregnate the fiber substrate with 10 to 40% by weight, particularly 15 to 30% by weight of the oil agent for dust adsorption. If the amount of oil is less than this range, the desired dust collection performance cannot be obtained, and if it is more than this range, the amount of oil that can be retained in the pores during cleaning may be exceeded and transferred to the surface to be cleaned. This causes disadvantages such as recontamination and an oily feel. The dust adsorption oil used in the present invention includes:
Normally non-volatile oils such as spindle oil, machine oil, liquid paraffin, mineral oil such as electrical insulating oil, alkylbenzene oil, diolefin oil, diester oil, alkylnaphthenate oil, etc. are preferably used.
This oil agent may contain one or more of cationic or amphoteric surfactants, fragrances, dyes, flame retardants, fungicides, antibacterial agents, etc., according to known formulations.
More than one species can be blended. The dust control product of the present invention is generally prepared by adding a cationic surfactant, a nonionic surfactant, etc. to the above-mentioned oil to prepare a self-emulsifying and self-exhausting oil composition, and dispersing this oil composition in water. It can be obtained by preparing an oil-in-water emulsion, immersing cleaning fibers containing the water-absorbing acrylic fibers in this emulsion to adsorb oil droplets, and dehydrating and drying the treated fibers. The cleaning fibers are impregnated with the oil by directly applying the dust adsorption oil by spraying or rolling, or by dissolving or dispersing it in a volatile solvent, and then drying the treated fibers. Of course, it can also be manufactured. When manufacturing the dust control product of the present invention, it also has the advantage that the dehydration and drying processes are performed much faster than conventional products, as will be described in the examples below. This effect is believed to be due to the water-absorbing acrylic fiber having good water discharging properties due to the above-mentioned structure. As mentioned above, the dust control product of the present invention has excellent cleaning properties such as excellent dust collection, dust retention and durability, and oil migration resistance.Furthermore, the water-absorbing acrylic fiber itself is lightweight. In addition, since it has the properties of acrylic fibers, such as excellent strength, durability, and dimensional stability, the dust control product of the present invention also has properties based on these properties, that is, the product itself can be made lighter. It retains its texture even after repeated use, and has excellent durability. The invention is illustrated by the following example. Example 1 As a dust control product according to the present invention,
Prepare oil-impregnated piles and oil-impregnated cloth as described below. Pile used: Single fibers of 5 to 10 denier are used, 40%
Water-absorbing acrylic fiber (Dounova, manufactured by Bayer) with a water absorption of 30%, regular acrylic fiber 70%
A mop is made using a pile yarn using three strands of yarn with a yarn count of 4, which is a blended yarn with a ratio of 1.5%, and is impregnated with spindle oil by spray coating at 20% by weight based on the weight of the yarn. It is an oil-impregnated fiber product for dust control. Cloth used: 10 count thread, which is a blend of 50% water-absorbing acrylic fiber (Dounova, made by Bayer AG) with 40% water absorption and 50% regular acrylic fiber, is used both vertically and horizontally to create a plain weave. The number of threads per inch is 35 vertically and 20 horizontally, and this is impregnated with spindle oil by spray coating at 20% by weight based on the weight of the thread to obtain the oil-impregnated cloth for dust control of the present invention. The dust collection rates of the oil-impregnated piles and oil-impregnated cloths prepared as described above were measured and are shown in Table 1. For comparison, similar piles and cloths were prepared using cotton fibers, and the dust collection rate was measured.
It is also shown in the table. Dust collection rate Place the sample and silica sand powder twice the weight of the sample in a plastic container, cover with a lid, and shake well to uniformly adhere the silica sand powder to the sample. This material is then subjected to constant mechanical vibration to shake off the silica sand powder that is weakly adhered to the cloth. The weight increase rate before and after this operation was defined as the dust collection rate. That is, dust collection rate = b - a / a x 100, where a: sample weight before test, b: sample weight after test

In addition, when comparing the amount of dust collected per unit area for cloth, the product of the present invention is lightweight, so compared to cotton fiber.
It can be seen that it is 16 mg/cm 2 , whereas in the case of water-absorbing acrylic fibers it is 21 mg/cm 2 , which is rather superior. Furthermore, an oily feel sensitivity test was conducted on the oil-impregnated pile and oil-impregnated cloth described above using 20 panelists. This sensitivity test was conducted by having the participants actually hold in their hands water-absorbing acrylic fiber products and cotton fiber products with identification codes attached, and answering the code of the sample that they felt did not have an oily feel. Regarding water-absorbing acrylic fibers in any case
We received 20 responses out of 20 people. Example 2 Using a cloth prepared in the same manner as in Example 1, the transfer amount and transfer rate of the dust adsorption oil agent were measured,
The results are shown in Table 2. In addition, the migration test is performed by leaving the sample fabric on paper under a constant load (15.6 g/cm 2 ) at 20°C and RH65%.
This test measures the amount of dust adsorption oil transferred to the object to be cleaned after 48 hours.
