Description

[Detailed explanation of the idea]

(Industrial Application Field) The present invention relates to a pine-like material that has good water absorption properties as a surface property, and good water absorption and water retention properties as an internal property. Due to its characteristics, even if it gets wet due to spillage, it does not give a cold feeling to the user and has a desirable dry feeling, and it also has high performance characteristics such as being easier to dry than similar conventional products. It is related to pine-like things. The pine-like product of the present invention takes advantage of the above-mentioned characteristics and can be used as a floor mat placed in the washroom, in front of the bathroom, in the kitchen, etc., a floor mat placed inside the toilet, and a toilet seat cover. It can be used optimally, and its characteristics can also be effectively used in various fields such as bedding materials, construction materials, and rags and rags. be. (Prior art) Mats that have traditionally been used for purposes such as floor mats placed in front of bathrooms and in the kitchen, as described above,
The main types are those with a pile structure made of 100% cotton, or carpet-like materials made of 100% cotton, 100% synthetic fibers, or a mixture of cotton and synthetic fibers. (Problems that the invention aims to solve) However, all of the previously used pine species mentioned above have the disadvantage that it is difficult to say that they have sufficient water absorption and water retention performance, and the water absorption rate is slow. It can be said that the amount of water retained is small, and the water absorbency of the floor surface is not sufficient. Among these, those made of cotton can be said to be better in terms of performance than others, but on the other hand, they have the drawbacks of being difficult to remove stains, difficult to wash, and taking a long time to dry. In addition, one thing that can generally be said about conventional products is that even if water is absorbed, it is often retained near the surface layer, and this is especially common with products made of cotton. If you stood on it, you would feel wet and cold, and it was not at all comfortable. In view of the above-mentioned points, the inventors of the present invention have conducted various studies in order to obtain pine with a good feeling of use, and have found that, in particular, for pine for the above-mentioned purposes, the characteristics of the pine surface such as spilled water etc. It can quickly absorb moisture from the pine and quickly transfer the moisture to the inside of the pine itself, and further retain the absorbed moisture inside the pine so that the water does not seep onto the floor etc. under the pine. We have obtained the knowledge that it is extremely effective to make a pine that can be used as a bath mat.If such a pine is used in front of a bathroom as a bath mat, for example, after one user uses it to wipe their feet after bathing, etc. However, the next person can use the mat comfortably without feeling wet or cold. The purpose of this invention is to improve the above-mentioned drawbacks of conventional mats, to improve water absorption on the surface and to quickly transfer moisture to the interior of the mat, and to effectively retain the transferred moisture inside the mat. To provide a mat-like article that can be optimally used as a comfortable floor mat in front of a bathroom, in the kitchen, in a washroom, etc., and is also easy to wash and dry. (Means for Solving the Problems) The pine-like object of the present invention that achieves the above-mentioned object has the following configuration. That is, a sheet-like article constructed using ultrafine synthetic fibers with a single fiber fineness of 0.05 to 1.0 denier;
It is a mat-like material having water absorption and water retention properties, which is made by laminating knitted fabrics or nonwoven fabrics made of fibers having a single fiber thickness larger than the single fiber thickness of the ultrafine fibers. In the pine-like article of the present invention, the fibers constituting the knitted fabric or nonwoven fabric may be synthetic fibers, in which case even better washability and drying properties can be obtained. In order to achieve all of the above-mentioned objectives such as water absorption, water retention, and drying properties at a high level, the fibers that make up the knitted fabric or nonwoven fabric should be synthetic fibers, and the single fiber fineness of the fibers should be the same as that of the sheet material. It is best to configure the fiber fineness to be at least 1.5 times the single fiber fineness of the ultrafine synthetic fiber. (Function) Hereinafter, the pine-like material of the present invention will be explained in more detail based on the drawings and the like. As the model structure is shown in FIG. 1, the mat-like material 1 of the present invention has a single fiber fineness of 0.05 to 1.0 denier on the floor side, that is, the side that will be lower when used as a floor mat. It consists of a sheet-like material 2 constructed using ultrafine synthetic fibers, and
On the surface side, that is, above the sheet-like material, a knitted or non-woven fabric 3 made of fibers having a single fiber thickness larger than that of the ultrafine fibers forming the sheet-like material 2 is laminated. That's what happens. In addition, in the figure, 4 is a base fabric that is used as necessary, and as the base fabric, an arbitrary fiber cloth base fabric or a lining material such as a urethane layer is used,
Further, 5 indicates the floor. In the pine-like material of the present invention, the relationship between the thicknesses of the single fibers constituting the surface layer and the inner layer is such that the inner layer is smaller and the surface layer is larger, so the distance between the single fibers in each layer is as follows: The surface layer becomes larger compared to the inner layer, which causes capillary action,
When water drips onto the surface of the mat, the water does not accumulate on the surface layer 3 of the knitted fabric or nonwoven fabric, but quickly moves from the surface layer 3 to the inner sheet-like material 2. The inner sheet material uses ultra-fine synthetic fibers of 0.05 to 1.0 denier, so it exhibits high water absorption performance as described above, as well as good water retention ability.Also, since it is a synthetic fiber, it is easy to wash. It is easy and has good drying properties, thus achieving the object of the present invention as described above. When using a single fiber fineness of more than 1 denier instead of using ultrafine synthetic fibers of 0.05 to 1.0 denier as the sheet-like material,
It is difficult to achieve good water absorption and water retention. There are no particular limitations on the manufacturing method for the sheet-like material constructed using ultrafine synthetic fibers with a single fiber fineness of 0.05 to 1.0 deniers, which is used in the present invention. Known sea-island type composite synthetic fibers or peelable type composite fibers are spun, the fibers are made into filaments or stapled and laminated to an appropriate number of layers, and then needle punching etc. are performed to make felt-like fibers. Preferably used are felt-like products obtained by making a product and then subjecting it to ultrafine treatment such as de-sea treatment, and sheet-like products obtained by laminating and entangling fiber bundles directly spun into microfibers. . By employing such a manufacturing method, the sheet-like article becomes a felt-like aggregate composed of fiber bundles that are aggregates of ultrafine fibers, and can fully exhibit the above-mentioned capillary phenomenon. As the above-mentioned ultrafine synthetic fibers, polyester fibers, polyamide fibers, etc. can be used as appropriate. In addition, the above sheet-like material does not necessarily need to be composed of 100% of the ultrafine synthetic fibers,
Other fibers may be mixed in for purposes such as reinforcement or cost reduction within the range that does not impair the effects of the present invention.According to the knowledge of the present inventors, generally 50% It is preferable that the ultrafine synthetic fibers be contained within a range of 100% by weight. The knitted fabric or nonwoven fabric 3 made of fibers having a single fiber thickness larger than the single fiber thickness of the ultrafine fibers, which is laminated on the above sheet-like material, is not particularly limited in its structure, and the constituent fibers are not particularly limited. 100% synthetic fiber or 100% chemical fiber
It may be made of 100% natural fibers, it may be made of blended yarns of these, or it may be made by mixing or knitting these, and may also be made of long fibers, short fibers, Any of these may be used in combination. According to the findings of the present inventors, the knitted fabric or non-woven fabric is most preferably made of long synthetic fibers in order to improve product quality and durability, and the single fiber fineness is within the range of 3 to 10 deniers. Practically preferred are knitted fabrics or nonwoven fabrics made of synthetic filament yarns. In other words, when the single fiber fineness is less than 3 denier, the anti-pilling and anti-snagging properties tend to be slightly inferior, and when it is greater than 10 denier, the fiber tends to feel somewhat rough and hard when used. It is in. However, these are also a matter of personal preference, and there is no problem in setting it outside the above range depending on the desired texture. In addition, in order to achieve all of the objectives such as water absorption, water retention, and drying properties at a high level with the pine-like material of the present invention, the fibers constituting the knitted fabric or nonwoven fabric should be synthetic fibers, and the fineness of the single fibers should be It is preferable that the fineness of the single fiber is 1.5 times or more the fineness of the ultrafine synthetic fibers constituting the sheet-like material. The above-mentioned sheet-like material and knitted fabric or non-woven fabric can be laminated by sewing means such as quilting sewing of the sheets that are simply layered as shown in Fig. 1, or point bonding with an appropriate adhesive. Alternatively, as shown in Fig. 2, the sheet-like material 2 may be placed inside a bag-shaped knitted fabric or non-woven fabric 3, and the sheet-like material 2 may be placed in the bag-shaped knitted fabric or non-woven fabric 3. The opening of the bag may be fastened with a zipper or the like, or a sewing method such as quilting as described above, or a fastening means as described above may be employed as appropriate. In the pine-like material of the present invention, it is preferable to use hydrophilic treated fibers for the sheet-like material, knitted fabric, or non-woven fabric, as this further improves water absorption and water retention performance. For example, in the case of using polyester fibers, the hydrophilization method includes a method in which about 1 to 2% by weight of a hydrophilized polyester resin is used for hydrophilization treatment. Of course, the pine-like material of the present invention may be used with a suitable cover within the range that does not impair its effectiveness. (Example) Composite fiber with a sea-island ratio of 50:50 (single fiber fineness 3.6
denier) to make staples with a length of 51 mm. The composition of this composite fiber has 18 islands,
After sea removal, the polyester fiber has a single fiber fineness of 0.1 denier. Using such staples, create a web using a roller card, and stack 30 layers of this to achieve the desired fabric weight.
1000 g/m ² of felt was produced. This felt is subjected to sea removal treatment of the composite fibers using a sea-based solvent (Trichlene) to produce a sheet-like material (thickness:
1.4mm) was obtained. Furthermore, using a high pressure dyeing machine on the sheet-like material,
2% by weight of hydrophilized polyester resin as a hydrophilic agent
A hydrophilic treatment was performed at 130°C for 1 hour. Furthermore, a knitted fabric was made using a 150 denier-30 filament yarn of polyester false-twisted modified yarn, and subjected to almost the same hydrophilic treatment as above. A bag-like object is made using this knitted fabric, and two superfine synthetic fiber sheets obtained above are placed inside it,
The opening of the bag was closed with a fastener to obtain the matuto-like material of the present invention. The results of various tests conducted on the pine of the present invention and commercially available cotton pile pine were as follows:
As shown in Table 1, it was confirmed that the pine of the present invention had good characteristics.

[Table] In Table 1 above, the water absorption rates were determined by the Larose method as described below. The water absorption rate was determined by dropping a 0.2 cc water droplet onto the mat surface and measuring the time required for the water droplet to disappear with the naked eye. In addition, the cold sensation was evaluated by sensory evaluation, and 100%
After 10 minutes, let the mat absorb 3 c.c. of water per cm ² .
The presence or absence of a cold sensation after 20 minutes and 30 minutes was evaluated. (1) How to measure water absorption using the Larose method: The Larose method uses the measuring device shown in Figure 3 to measure the amount of water that a sheet placed on foamy glass wool absorbs in a predetermined time. Tell me how to measure using the steps below. Cut the sheet into a circle with a diameter of 6 cm, condition the humidity at 20°C and 65% RH, and measure the sample weight (g). Water supply container a held at the top of the device in Figure 4
Inject water b at 20°C. Open the water supply container c and remove the water absorption measuring tube d.
Fill the water up to the tip of the water absorption test part e.
Raise the water to the top of the glass wool filter h (diameter 6.5cm, standard: 17G). Close Kotoku G and glass wool filter H
A filter paper is brought into contact with the top surface of the filter to absorb excess water, and by this operation, the scale of the water absorption measuring tube d is set to 0 (zero). Gently and flatly place the circular sample g prepared above on the top surface of the glass wool filter h using tweezers. Immediately place a brass weight f (480 g) with a diameter of 6 cm on top of this sample, and at the same time begin measuring time with a stopwatch. After 1 minute, 2 minutes, and 5 minutes have passed, read the scale on the water absorption measuring tube d to determine the amount of water absorbed (g) at each time. Then, the water absorption rate is determined according to the following formula. Water absorption rate = {(water absorption amount)/(sample weight)} ×100 (%) The measurement was performed five times, and the water absorption rate at each time was expressed as an average value. In Fig. 4, i is a flexible tube, j is a stand, and k, l,
All m are supports. (Effect of the invention) According to the pine-like material having water absorption and water retention properties of the present invention as described above, the relationship between the thicknesses of the single fibers constituting the surface layer and the inner layer is such that the inner layer is smaller and the surface layer is smaller. Since the side is large, the space between the single fibers in each layer is larger in the surface layer than in the inner layer, so that even when water drips onto the surface of the pine-like material due to capillary action, the moisture is absorbed. It is capable of quickly transferring and diffusing from the surface layer to the inner layer of the ultrafine synthetic fiber sheet without accumulating on the surface layer of the woven or nonwoven fabric, and the inner layer of the ultrafine synthetic fiber sheet has high water absorption performance. Because it has a good moisture retention capacity, the pine-like surface always feels dry without giving the user a wet or cold feeling, and is comfortable to use. It is something that can be done. According to the studies conducted by the present inventors, in the pine-like material of the present invention, which has particularly good properties, the water retention rate of the ultrafine synthetic fiber sheet generally shows a high value of about 300%, and this allows for a long period of time. Not only can it be used for washing and drying, the matte-like material can be used as is, or in some cases, the ultra-fine synthetic fiber sheet can be removed and washed separately. It is also possible to subject it to drying. In any case, the pine-like material of the present invention using synthetic fibers has better washability and drying properties than conventional cotton-based products. I can do it. According to this invention, it can be used in various fields such as floor mats laid in washrooms, in front of bathrooms, in kitchens, etc., floor mats laid in toilets, toilet seat covers, etc., as well as bedding materials, construction materials, etc. The present invention provides a pine-like material that has great practical value and can be effectively used for various purposes such as rags, rags, and waste cloths by taking advantage of its characteristics.
