Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber assembly for cleaning rags, mops, etc. used for business or household use.

[0002]

2. Description of the Related Art As a cleaning fiber aggregate of this kind, a so-called chemical wipe is known, which is obtained by impregnating or coating a non-woven fabric, paper or the like with an oil agent component such as natural oil or synthetic oil. This chemical rag is widely used as a cleaning tool for wiping off dust accumulated on or adhering to floors, walls, furniture, etc. without scattering.

In such a conventional chemical rag, etc., an oil agent component is applied to the base material in order to improve the dust collecting property. However, during repeated use, the oil agent component gradually becomes a surface to be cleaned. However, there is a problem in that the dust collecting property gradually decreases due to the shift to the side. In order to prevent such deterioration of dust collecting ability, a large amount of oil agent component is applied to the conventional chemical rag, and a large amount of oil agent remains as an oil film on the surface to be cleaned, so that the user etc. There was the inconvenience of giving discomfort to.

In order to solve such a problem, Japanese Unexamined Patent Publication (Kokai) No. 57-39825 discloses that a non-dried vegetable oil having a viscosity higher than that of a mineral oil is used as an oil agent to reduce the dust collecting property during repeated use. A technique for preventing the above is disclosed.
Further, JP-A-59-140282 discloses a technique of increasing the adhesiveness of an oil agent to a base material by mixing a wax component and a liquid lubricating oil to prevent the oil agent from migrating to a surface to be cleaned. It is disclosed.

[0005]

However, these techniques described above improve the cohesive force of the oil agent and prevent the oil agent from falling off from the cleaning fiber, so that the dust collecting property during repeated use can be improved. Is not to be lowered, and the transfer of the oil agent cannot be completely suppressed. Therefore, there is a problem in that the dust collection performance during repeated use due to repeated wiping and the like decreases.

Further, if the cohesiveness of the oil agent is simply improved, the wettability with respect to dust may be deteriorated, and the dust collecting property may be adversely affected. Therefore, the object of the present invention is to
An object of the present invention is to provide a cleaning fiber assembly capable of preventing the dust collecting property from being deteriorated during repeated use.

[0007]

The present invention is a cleaning fiber assembly in which a gel-like cleaning oil agent is held on a fibrous base material, wherein the cleaning oil agent is a thermoplastic elastomer and a natural oil. The above object is achieved by providing a cleaning fiber assembly comprising: and / or a synthetic oil.

[0008]

According to the cleaning fiber assembly of the present invention, since the gel-like cleaning oil agent retained on the base material is composed of the thermoplastic elastomer and the natural oil and / or the synthetic oil, the cleaning oil agent aggregates. It improves the force and prevents the cleaning oil from transferring to the surface to be cleaned during repeated use, resulting in
This is to prevent the dust collecting property from being deteriorated during repeated use.

[0009]

EXAMPLES A cleaning fiber assembly according to the present invention comprises a fibrous base material which holds a gel-like cleaning oil agent, and the cleaning oil agent is composed of a thermoplastic elastomer and natural oil and / or synthetic oil. Is characterized by. As the fibrous base material, a woven cloth, a non-woven cloth, paper, or a mop-like material in which fibers are twisted together can be used. More specifically, natural fibers such as cotton, hemp, and pulp, semi-synthetic fibers such as rayon and cupra, and synthetic fibers such as polyolefin, polyester, and polyamide are used as fibers forming the base material (fiber aggregate). You can

The thermoplastic elastomer is preferably a block copolymer such as SBS (styrene-butadiene-styrene), SIS (styrene-isoprene-styrene), SEBS (styrene-ethylene / butylene-styrene). As the natural oil, olive oil, castor oil, rapeseed oil, camellia oil and the like can be used. Among these, those having good wettability to the surface to be cleaned and excellent stability may be used.

As the synthetic oil, liquid paraffin, silicone oil and the like can be used. Among them, those which have good wettability to the surface to be cleaned and have excellent stability, like the above natural oils. Used. Further, when adjusting the gel of the cleaning oil agent, an organic solvent is used, but such an organic solvent can be selected from those having compatibility with both the thermoplastic elastomer and the oil component, for example, chloroform, Toluene, xylene, methyl ethyl ketone (MEK), tetrahydrofuran (THF) and the like can be used.

A solution prepared by dissolving the thermoplastic elastomer and the above-mentioned natural oil and / or synthetic oil in an organic solvent contains the thermoplastic elastomer and the natural oil and / or synthetic oil in an arbitrary ratio. The ratio of the thermoplastic elastomer to the natural oil and / or the synthetic oil is selected so that the surface to be cleaned exhibits a good cleaning state and the cohesive force required for the cleaning oil agent not to move is obtained. The ratio of such a thermoplastic elastomer to a natural oil and / or a synthetic oil is preferably 0.1 to 5 when the amount of the thermoplastic elastomer in the final gel is the standard.
It is 0% by weight, particularly preferably 1 to 20% by weight. 0.
If it is less than 1% by weight, it becomes difficult to gel and the cohesive force is lowered. On the other hand, if it exceeds 50% by weight, the effect of the cleaning oil agent is hindered from exerting, so that the dust collecting property may be lowered. This is because.

A surfactant may be contained in the gel-like cleaning oil agent for the purpose of improving the wettability of the cleaning oil agent with respect to the surface to be cleaned. The amount of the cleaning oil held on the base material is preferably in the range of 1 to 100% by weight, and particularly preferably 1 to 50% by weight, based on the weight of the base material. If it is less than 1%, the dust collecting property is not sufficient, and 1
This is because if it exceeds 00% by weight, the sliding resistance with respect to the surface to be cleaned becomes large and it becomes difficult to clean.

The gel concentration of the cleaning oil agent is preferably adjusted by the ratio of the oil component and the thermoplastic elastomer.
When porous fibers, fibers that absorb the cleaning oil, or the like are used, it is preferable that the amount of the cleaning oil to be held is relatively large. In order to retain the cleaning oil agent on the substrate, it can be applied by a method using a spray or a roll coater. In this case, it is preferable that the organic solvent is held on the base material in a solution state and then the solvent is removed to form a gel.

The product of the present invention will be described below in comparison with a comparative product. (Practical product) SBS (Shell Chemical Co., Ltd. TR1101) and liquid paraffin (Chuo Kasei Co., Ltd. 350S) were used as cleaning oils, and SBS was 5% by weight.
95 wt% liquid paraffin was dissolved in chloroform,
This was sprayed onto a nonwoven fabric made of polyester (basis weight: 40 g / m ² ) to apply 10% by weight of the nonwoven fabric to obtain a cleaning fiber assembly.

The non-woven fabric used was prepared as follows. Polyester fiber 1.5 denier, 51 mm was formed into a fiber aggregate having a basis weight of 8 g / m ² by a conventional card, and the fiber aggregate was wrapped into 5 layers (40 g / m ² ) (not shown), As a mesh sheet, a biaxially shrinkable polypropylene net (distance between wires 9 mm, wire diameter 0.2 mm) was laminated on the upper and lower layers of the intermediate layer, and then entangled with a water needling.

(Comparative product) Liquid paraffin (350S, Chuo Kasei Co., Ltd.) as a cleaning oil was applied to a nonwoven fabric made of polyester (basis weight: 40 g / m ² ) at 10% by weight based on the weight of the nonwoven fabric to collect cleaning fibers. Got the body As the non-woven fabric, a non-woven fabric prepared in the same manner as the above-mentioned product was used.

(Test method) In the dust collecting test, a test dust (JISZ-8901) was used to examine the collecting ability on the decorative plate. The results are shown in Table 1 below. The collecting ability in repeated use was examined in the same manner as the above test after wiping the decorative board.

The transferability of the cleaning oil (oil transfer) was examined by wiping the matte blackboard to check the gloss of the cleaning oil. The dust retaining property was evaluated by tapping the test cloth obtained by the dust collecting property. Table 1 below shows the results of the tests of the collecting property and the like after cleaning using the above-mentioned product and the comparative product.

[0020]

[Table 1] ⊚: Good ○: Normal Δ: Slightly inferior ×: Inferior As is clear from Table 1, the dust trapping property after repeated use is inferior to that in the initial use, whereas
With the implemented product, it was possible to obtain a result that was almost the same as the initial use. That is, according to this example, even after repeated use, it was possible to obtain the same dust trapping property as in the initial use.

Also, in terms of oil agent transferability and dust retention, the practiced product was able to obtain better results than the comparative product. Next, preferred specific examples of the base material constituting the cleaning fiber assembly of the present invention will be described with reference to FIGS. 1 to 5.
1 is a sectional view of a cleaning fiber assembly according to an embodiment of the present invention, FIG. 2 is a perspective view of a cleaning fiber assembly according to another embodiment of the present invention, and FIG. 3 is a cleaning view shown in FIG. It is sectional drawing which shows the state which cut | disconnects the fiber assembly for cleaning along a XX line, FIG. 4 is an expanded sectional view which shows the fiber assembly for cleaning shown in FIG. 3, and FIG. 5 is a mesh sheet. It is a top view of the net used as.

The cleaning fiber assembly 10 according to the present embodiment is
As shown in FIG. 1, after the first sheet 12 is laminated on one side or both sides of the mesh sheet 11 which is uniaxially or biaxially heat-shrinked, the first sheet 12 is placed on one side of the mesh sheet 11 by water flow.
The fibers of the sheet 12 and the fibers of the first sheet 12 on the other side, and the fibers of the first sheet 12 and the mesh sheet 11 are entangled and integrated, and at the same time, the first sheets 12 and 12 are entangled nonwoven fabrics. When the heat-shrinkable mesh sheet 11 is heat-shrinked at the same time as the drying process or separately from the drying process, the constituent fibers of the non-woven fiber web are swelled and arranged in a wavy pattern to form a base material. 14 is provided with an uneven shape as a whole.

According to the cleaning fiber assembly 10 of this embodiment, since the non-woven fiber web constituting the substrate 14 and the substrate 14 as a whole are provided with uniform bulkiness, the degree of freedom of the fibers is remarkably increased. It is possible to improve the strength, and the non-woven fabric-like fiber assembly portion having a low degree of entanglement can be given practical strength by means of a mesh sheet. In particular, in order to develop a flexible uneven shape on the surface of the bulky sheet,
It is possible to easily entangle the dust that comes into contact with the cleaning fiber aggregate.

A cleaning fiber assembly 10 according to another embodiment.
2 to 5, the fiber assembly as the base material 14 is formed integrally with the mesh sheet 11 by the entanglement of the fibers. The base material 14 is formed by partially bonding the first sheet 12 and the second sheet 15 which is a heat-shrinkable sheet. On the surface of the first sheet 12, a large number of relatively small first uneven portions 14A,
14B is formed, and the first sheet 12 as a whole is formed on the second sheet 15 with relatively large second uneven portions 10A and 10B.

The first sheet 12 has a non-woven fabric-like base material 14 composed of entangled fibers on one or both sides of the reticular sheet 11 together with the entanglement of the constituent fibers.
Also, the first sheet 12 is provided with first uneven portions 14A and 14B that are relatively small unevenness due to the contraction of the mesh sheet 11 and are integrally formed in a entangled state. As described above, a nonwoven fabric formed by entanglement of fibers has a greater degree of freedom of constituent fibers than a nonwoven fabric formed by only fusing or adhering fibers, and the entanglement retention of dusts and the fibers is very high. Higher dust collection performance.

Further, the first sheet 12 is a heat-shrinkable second sheet.
The sheet 15 is partially bonded to one side or both sides (one side in this embodiment) of the sheet 15, and the first concavo-convex portion 14 is formed as a whole of the cleaning fiber assembly by contraction of the heat-shrinkable second sheet 15.
A second uneven portion 10A having unevenness larger than A and 14B,
10B is formed on the second sheet 15. That is, the cleaning fiber assembly 10 has a relatively large second uneven portion 10
A and 10B and relatively small first uneven portions 14A and 14B are formed.

The heat-shrinkable net 11a as the mesh sheet 11 is formed in a lattice shape as a whole as shown in FIG. The basis weight, fineness, fiber length, cross-sectional shape, entanglement degree, and strength of the fibers forming the base material 14 are determined in consideration of workability, cost, etc., in accordance with the purpose of use. In particular,
The basis weight is 15 to 15 before shrinking to a predetermined size.
It is suitable to be 0 g / m ² . Basis weight is 15g / m
^{When it is} less than ² , it is difficult to obtain the necessary and sufficient degree of entanglement and strength, and when it is used as a cleaning fiber assembly, fluff may come off, and when it is more than 150 g / m ² , it is disadvantageous in terms of cost. Is.

Although the fineness of the base material 14 also affects the entanglement,
0.5-6.0 denier is suitable. If it is thinner than 0.5 denier, the web-forming property becomes very poor, and if it is thicker than 6.0 denier, the entanglement is difficult and the retention of dusts becomes poor. As the mesh sheet 11,
A heat-shrinkable material is preferably used, and when the net 11a is used as the mesh sheet, a polyolefin-based material;
For example, polyethylene, polypropylene, polybutene, etc., polyester type; for example, polyethylene terephthalate, polybutylene terephthalate, etc., and vinyl type,
Vinylidene type; for example, polyvinyl chloride, polyvinylidene chloride, polyamide type; for example, a net 11a made of a thermoplastic polymer such as nylon 6, nylon 66, etc. or their modified products, mixtures, etc. Which is uniaxially or biaxially contracted, or a filament which is heat-shrinkable with the above-mentioned polymer is used for at least one of the warp and the weft, a woven or knitted net is preferable, and the necessary first uneven portion 14A, 14B.

Net 11a as the mesh sheet 11
It is necessary to determine the size of the lattice, the diameter of the wire, and the like in consideration of the shrinkage force, the shape of the uneven portion due to the shrinkage rate, the degree, the partial entanglement with the non-woven fiber aggregate, and the like. Specifically, the wire diameter is preferably 500 to 20 µ, more preferably 200 to 100 µ, and the shape of the lattice is not limited, but the opening area is 4 to 900 mm ² , and more preferably 1
It is 0 to 200 mm ² . If the grid of the net 11a, that is, the area of the open holes is large, and the area is larger than 4 mm ² , the net 11a is
Since the fibers of the fiber assembly existing on both sides of the net 11a sandwich the holes of the net 11a and are strongly entangled with each other, it is easy to form a convex portion in the hole portion of the net 11a. On the other hand, when the lattice is small or the wire diameter is large, the entanglement between the fibers on the front surface and the fibers on the back surface existing on the net wire increases, so that the concave portion is formed in the hole portion of the net 11a contrary to the above case. Easy to form.

As the heat-shrinkable second sheet 15,
Polyolefin type; for example, polyethylene, polypropylene, polybutene, polyester type; for example, polyethylene terephthalate, polybutylene terephthalate, etc., and vinyl type, vinylidene type; for example, polyvinyl chloride, polyvinylidene chloride, polyamide type; for example, nylon 6, A film sheet of nylon 66 or the like, a modified product thereof, or a mixture thereof is suitable, and a material that shrinks in the uniaxial or biaxial direction is appropriately selected according to the required shape of the second uneven portions 10A and 10B.

The thickness of the second sheet 15 should be determined in consideration of the shrinking force, the shape of the uneven portion due to the shrinkage ratio, the degree, the partial joining workability with the non-woven fiber aggregate, and the like. However, a thickness of about 10 to 40 μm is appropriate. Also,
The resin of the second sheet 15 may be appropriately selected in consideration of the bondability with the non-woven fiber aggregate 14 to be bonded. The present invention is not limited to the above-described embodiments and can be variously modified without departing from the gist of the present invention.

For example, the application of the cleaning oil agent is not limited to the application by spraying, but it may be performed by immersing it in a solution or the like for impregnation.
