DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping cloth for wiping water. More specifically, after dirt has adhered,
The present invention relates to a wiping cloth from which dirt is quickly removed from a cloth by washing with water or other washing. Furthermore, the present invention relates to a wiping cloth which is easy to work with water and does not leave traces of water droplets and dirt after wiping.

[0002]

2. Description of the Related Art As represented by eyeglass wiping, fabrics using ultra-fine fibers of 1 denier or less have very good performance of removing dirt such as oil and have been developed for various uses.

However, since the wiping cloth generally used is made of a woven fabric, a nonwoven fabric, or a felt, the dirt entering the fiber gap is not easily removed from the fabric during washing or the like. Although it can be used without problems in fields with little dirt, such as spectacle lenses, optical components, musical instruments, and furniture surfaces, it can be used to remove dirt from highly contaminated areas such as windows, window frames, car windows, and car bodies facing the open air. Can remove dirt from the material to be wiped,
In the cloth from which the dirt has moved, the cloth turned black immediately, and the dirt could not be easily removed, and there was resistance to repeated use.

Further, wiping with water to remove dirt and dust is a commonly used technique.
Normally used wiping cloths are supposed to be used in a dry state.If they are used for wiping with water, they will not only be difficult to wipe off due to low weight per unit area and low water retention, etc. However, there is a problem that the data remains. In addition, a wiping cloth composed of a plain weave is integrated with a porous body such as a sponge to give a sense of volume. However, even with the wiping material, there is no solution to the problem that water droplets remain on the wiping marks.

[0005] The problem that water droplets remain after wiping occurs also in generally commercially available rags and the like, and does not simply mean that the wiping cloth only needs to have water absorption.

[0006] On the other hand, a proposal to use a napped fabric using ultrafine fibers for dust removal has already been made in Japanese Patent Application No. 2-98360. However, these proposals are for removing dirt present in the liquid or on the liquid surface, and when wiping the dirt on the solid surface, and as a wiping cloth for wiping with water, use a napped fabric using ultrafine fibers. There was no idea of using it.

[0007]

SUMMARY OF THE INVENTION The present invention solves these problems and enables smooth wiping with water.
Further, the present invention provides a wiping cloth which does not leave wiping marks such as water droplets and stain marks, and which quickly removes stains adhering to the cloth by washing or washing.

[0008]

[SUMMARY OF] To achieve the above object wiping of the present invention the cross consists raised fabric is less ultrafine fiber single fiber fineness of forming a napped part of the fabric 1d, standing bristles density Is more than 60000 pieces / cm ² , standing hair length
Is 2 mm or more and 15 mm or less, and a napped fabric in a dry state.
This is a napped wiping cloth for wiping with a total basis weight of 200 g / m ² or more .

[0009]

Hereinafter, the present invention will be described in detail.

[0010] The wiping cloth of the present invention uses ultrafine fibers effective as a wiping cloth as nap fibers, and has specific nap fineness and nap length to remove stains attached to the cloth quickly by washing. This is characterized in that the wiping cloth has excellent water wiping performance that does not leave a wiping mark by providing water absorption based on a capillary phenomenon by setting the nap density to be high.

That is, in a wiping cloth made of a material such as a woven or knitted fabric, a nonwoven fabric, or a felt, it is very difficult to remove dirt particles that have entered between the single fibers. Since the fibers are composed of fibers, the single fibers are easily separated from each other at the time of washing, and the dirt particles entering the fiber gaps are easily released.

Further, since the wiping cloth of the present invention is an ultra-fine fiber, it is softer than a yarn having a fineness of a normal thickness, and is tightly adhered to a dirt surface when wiping, so that dirt particles are easily entangled inside. This is because if you wipe with a thick napping cloth, as if you traced it with a brush,
The present invention solves the problem that dirt remains along fiber traces and dirt removal performance is insufficient. This performance is more effective in the presence of a small amount of water in a squeezed state, rather than in a dry wipe.

[0013] The napping fibers in the wiping cloth of the present invention are thinner, the higher the wiping performance, the greater the gap between the fibers, and the easier it is to take in dirt particles. In addition, the effect of the later-described capillary phenomenon is great. In order to perform these actions sufficiently, the fineness of the single fiber is preferably 1d or less,
More preferably, it is 0.4d or less.

In the napped wiping cloth of the present invention, the napped density is preferably as high as possible. This makes it possible to leave no trace of water on the trace of wiping when performing wiping. In a conventional wiping cloth, moisture pushed out of the cloth by hand pressure at the time of wiping is usually not completely re-absorbed by the cloth and partially remains on the object to be wiped. In order to solve this problem, it is sufficient to adopt a structure that causes a capillary phenomenon in the cloth. The denser the nap fibers are, the more easily the capillary phenomenon occurs and the better the drainage property is. Specifically, it is sufficient if the number is 60,000 lines / cm ² or more, preferably 100,000 lines / cm ² or more, and more preferably 20 or more lines / cm ^2.
0000 lines / cm ² or more.

The nap fiber length of the wiping cloth according to the present invention needs to be long enough that the nap fiber lies to some extent by hand pressure during wiping, so that dirt particles are involved and picked up. On the other hand, if the length is too short, the picked-up dirt particles will be detached on the spot, or conversely immediately reach the ground structure of the wiping cloth, making it difficult to remove dirt during washing, which is not preferable. However, if the nap length is too long, the fiber gap may not be effectively utilized, and the abrasion of the fabric may be accelerated. From these points, the preferred length of the ultrafine nap fiber in the present invention is 2
mm to 15 mm, more preferably 4 mm to 10 mm. The total fineness of the nap fiber is generally 30 to 500 denier, but is not particularly limited to this.

The fibers constituting the napped fabric in the present invention can be any ordinary fibers without any particular limitation. The material of the nap fiber and the fiber constituting the base cloth may be the same or not. Conventional synthetic fibers, regenerated fibers, and natural fibers can be used. Specific examples of the polymer constituting the synthetic fiber include polyester, polyamide, polyacrylonitrile, polyethylene, polypropylene, polyvinyl chloride,
Polyvinylidene chloride, polyvinylidene fluoride, polyether, polyimide, polyvinyl alcohol, polyvinylpyrrolidone, polysulfone, polyphenylene sulfide, polyurethane, polyacrylic acid, polyarylate,
Polymethacrylate, polymethyl methacrylate and the like can be used, and as regenerated fibers, rayon, cellulose, regenerated cellulose and the like, and natural fibers such as cotton can be used. Particularly, polymers such as polyester, polyamide, polyphenylene sulfide, polyarylate, polypropylene, polyethylene, etc. obtained by melt spinning are preferred from the viewpoint of easiness of producing an ultrafine yarn having a denier of 1 denier or less. In consideration of cost and cost, polyester and polyamide are more preferable. On the other hand, the material of the base fabric does not need to be particularly fine fibers, and any material can be used.

In order to maximize the effect of the present invention,
It is more preferable that the polymer constituting the cloth itself is a polymer having high hydrophilicity in that the cloth to which dirt has adhered is easily removed from the cloth when the cloth is washed. On the other hand, the raised fibers are preferably non-water-retaining in order to move moisture into the fabric by capillary action so that no water droplets remain after wiping. Considering these combinations, synthetic fibers such as nylon and PVA are more preferable as the nap fibers. Further, in these respects, rayon or the like which is highly hydrophilic and does not involve dirt such as fibrillation is preferred as the material of the base fabric which does not require the use of ultrafine fibers. In consideration of actual production, it is possible to use, for example, polyester or polyamide, for which ultrafine fibers can be easily produced, as the raised fibers, and to use rayon having high hydrophilicity for the fibers constituting the base fabric.

The base material constituting the napped wiping cloth of the present invention is not particularly limited, and may be any of a woven fabric, a knitted fabric, and a non-woven fabric. Therefore, a woven fabric is preferable to a nonwoven fabric, but it is preferable that the woven fabric be composed of filaments rather than staples, and that the number of filaments be small and the fineness be high.

The raised fabric in the present invention is not particularly limited, and includes, for example, a pile woven fabric obtained by a pile loom such as a single pile, a double pile, a double velvet, a chinchilla weave, and the like.
It is a collective term for all things such as tricot, napped knitted fabric obtained by a Russell knitting machine, and napped fabric obtained by post-processing such as buffing and napping. Further, it also includes a woven or knitted fabric using chenille yarn or a fabric obtained by flocking.

In the wiping cloth of the present invention, when the fiber material is a hydrophobic material such as polyester,
Applying a hydrophilic treatment to the surface does not matter at all.

In the present invention, such a hydrophilizing agent may be imparted without changing the fineness of the fibers constituting the fabric and not impairing the texture of the fabric remarkably. It is preferred that the film be provided extremely thinly on the surface. In the wiping cloth according to the present invention, it is difficult to remove the dirt that has reached the base cloth from the nap portion due to its structure, and it is preferable that the above-mentioned hydrophilization treatment is applied to the entire cloth. The effect can be fully exhibited if it is made on cloth.

Known treatments can be applied to the hydrophilic treatment in the present invention. For example, a method in which a hydrophilic polymer resin is immersed in the fiber surface, or a method in which a hydrophilic monomer is polymerized and fixed to the fiber surface by steaming or the like can be used. Examples of the treating agent include acrylic acid type, methacrylic acid type, polyethylene glycol type, sulfonated polyester type, melamine type resin, acrylic acid derivative quaternary ammonium salt polymer, and water-soluble polyalkylene described in JP-B-53-47437. Block copolymers of glycol, terephthalic acid and ethylene glycol can be used, but are not limited thereto. For polyester,
Hydrophilization can also be achieved by treatment with a dilute alkaline solution. Furthermore, physical means such as plasma processing may be used.

If necessary, one or more additives such as an antistatic agent, a hard finishing agent, and a softening agent may be appropriately compounded in the treatment agent.

The wiping cloth according to the present invention has a sufficient capillary phenomenon and exhibits excellent drainage properties. However, it is necessary to set an appropriate water content in advance by hand squeezing at the time of use. In performing this operation, if the entire fabric is too thin, it is difficult to draw down and it is difficult to control the water content. Therefore, it is preferable to have a certain amount of basis weight, and it is desirable that the total weight of the fabric is 200 g / m ² or more, more preferably 250 g / m ² or more.

0:20), 75 denier and 18 filaments are used as the nap warp yarn, 75 denier and 24 filament nylon 6 temporary warp yarn are used as the ground warp yarn, 150 denier and 3 denier.
Using a 6-filament nylon 6 temporary warp yarn as a ground weft yarn, a vertical double-wool fabric having a nap length of 7 mm was obtained. At this time, the weaving density was 45.5 yarns / inch, ground warp yarn 9
1 / inch and ground weft 92 / inch. Next, the cloth was treated with trichloroethylene to remove the sea component of the nap fibers, and a cloth made of ultrafine nap fibers having a single fiber fineness of 0.2 d was obtained. The basis weight of the fabric was 300 g / m ² . The nap density is calculated to be about 370,000 fibers / cm ² . Then, as described in JP-A-60-134070, the cloth was treated with a liquid dyeing machine, and the dicarboxylic acid component contained 5- (sodium) -sulfoisophthalic acid in an amount of 30 mol% based on the liquid-treated product. The terephthalic acid is 50 mol%, the isophthalic acid is 20 mol%, and the alcohol component is a 10% solution of a sulfopolyester resin containing 80 mol% of ethylene glycol and 20 mol% of diethylene glycol. The temperature gradually rises from room temperature under 30,
The treatment was performed at 130 ° C. for 35 minutes.

Next, when the resin was dehydrated and dried, the amount of the adhered resin was 0.5%.

After immersing the obtained extra fine upholstery fabric in water,
When the TV screen, which had been squeezed relatively tightly and dust was accumulated due to static electricity, was wiped with water, the screen after the wiping was not only cleaned, but no wiping marks such as water droplets were observed, and the screen was clean. On the other hand, the stains attached to the television were blackened on the extra-fine napkin cloth, but all the stains were removed by washing with water, and the original cloth was obtained.

Example 2 As the napping fiber, the same fiber as in Example 1 was used, and as the fiber constituting the base cloth, rayon was used to produce an ultra-fine napping cloth having a napping length of 8 mm.

When the cloth was used for wiping the dirt as it was, it showed a wiping performance comparable to that of Example 1 and a good dirt-removing property by subsequent washing with water, even though the surface was not subjected to hydrophilic treatment. Was.
