The present invention relates to a cleansing fabric (Cleansing Fabric) and a method for manufacturing the same, more specifically, excellent in removing the contaminants, soft to the touch, to prevent surface damage of the decontamination object to remove the cosmetics remaining on the skin The present invention relates to a fabric particularly useful as a fabric for wiping, such as a cosmetic cleansing cloth, an optical element and an optical storage medium, and a manufacturing method thereof.

As a conventional technology for the fabric for removing contaminants, Korean Patent Laid-Open Publication No. 1994-1987 proposes a method for manufacturing a cleaning polyester fabric using a yarn which is air-entangled with a highly shrinkable polyester yarn and a two-component polyester composite yarn as a weft yarn. have. However, the polyester fabric prepared by the above method has a problem in that the monofilament of the monofilament constituting the weft yarn exceeds 0.3 denier, thereby degrading pollutant removal performance and feel.

On the other hand, Japanese Laid-Open Patent Publication No. 2003-95868 proposes a cosmetic wiper which is a nonwoven fabric containing 20% or more of the ultrafine fibers having a single yarn fineness of 0.5 dtex or less relative to the surface area.

However, since the cosmetic wiper is a non-woven fabric rather than a fabric, the shape is deformed when used for a long time, that is, the fiber density becomes non-uniform, resulting in a large deterioration of the dirt removal performance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fabric for removing contaminants useful for cleaning fabrics or cosmetic cleansing fabrics such as precision products and optical devices by solving such conventional problems.

The present invention is to provide a contaminant-removing fabric, particularly useful for cosmetic cleansing fabrics, wiping fabrics such as precision products and optical devices, such as excellent in the removal of contaminants and soft to the touch and does not damage the surface of the decontamination object.

The contaminant removing fabric of the present invention for achieving the above object is a synthetic fiber multifilament made of ultra-fine yarn of 0.001 to 0.2 denier or a false twisted yarn thereof, the warp and weft yarn, any of the surface and the back surface of the fabric It is characterized in that the uneven pattern by embossing is formed in at least one.

In addition, the present invention uses a synthetic fiber multifilament made of a bicomponent composite yarn having a single yarn fineness of 0.001 to 0.2 denier or a false twisted yarn thereof as a warp and weft yarn after dissolving or dividing the sea component. The woven fabric is rinsed in an aqueous alkali solution and eluted or divided into sea components at the same time, and then dyed or dyed woven fabric and then eluted or divided into sea water in an alkaline aqueous solution, and the unevenness of the dyed fabric uneven pattern Embossing treatment with a processor, characterized in that for producing a fabric for removing contaminants.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

The warp and weft yarn constituting the contaminant removing fabric (hereinafter abbreviated as "fabric of the present invention") is a synthetic fiber multifilament made of ultra-fine fibers (single-fiber fibrils) of 0.001 to 0.2 denier or its flammable work.

It is more preferable that the fineness of the said ultra-fine yarn (single yarn fibrils) is 0.005-0.05 denier.

The inclined direction density of the ultra-fine yarn is 100,000 bones / inch to 1,000,000 bones / inch, and the weft direction density of the ultra microfibers is 50,000 bones / inch to 500,000 bones / inch.

When the warp density and the weft direction density are lower than the above ranges, the shape stability of the fabric may be deteriorated, causing problems such as rubbing of the fabrics over long periods of use, and when exceeding the above ranges, manufacturing processes such as weaving may be difficult. In addition, manufacturing costs may also increase.

Since the ultrafine yarn (single-fibrils) has very low fineness, the degree of freedom is high, and in order to destroy them sufficiently, it is necessary to weave a dense tissue. Therefore, the textile tissue of the present invention is a plain weave, runner or twill, or a tissue in which the plain tissue of the plain weave, runner or twill and the pattern forming tissue of the texture are used together. More preferably, the plain weave is good, and a twill weave with a short repeat section can be used.

Conventional cleaning fabrics were mainly woven in twill to improve dirt removal performance, but the fabric of the present invention is more preferably a plain weave or a short twill weave.

Synthetic fiber multifilament made of the ultrafine yarns described above as warp and / or weft yarns, that is, yarns that are not flammable after spinning and stretching, may be used, but the warp and weft yarns may slip against each other in the fabric structure to prevent the appearance of undesired phenomenon. In order to further improve the pollutant removal performance, it is more preferable to use a twisted yarn manufactured by twisting the synthetic fiber multifilament as warp and / or weft yarn.

Specifically, it is preferable to use the twisted yarn as the warp yarn and to use the synthetic fiber multifilament that is not flammable as the weft yarn, or to use the twisted yarn as both the warp yarn and the weft yarn.

The false twisted yarn can be manufactured by processing a two-component composite yarn in the same process as in FIG.

The two-component composite yarn is island-in-the-sea composite yarn or split composite yarn, and the synthetic fiber multifilament is most preferably polyester multifilament, but the material is not particularly limited.

On the other hand, the woven fabric of the present invention is formed with an uneven pattern on the surface and / or back.

The concave-convex pattern is formed by embossing. Embossing to form the concave-convex pattern is carried out by heating and pressurizing the fabric while passing the fabric between the etched embossed rollers. ~ 300kgf, embossing temperature is 13 ~ 150 ℃, the embossing work speed is preferably 5 ~ 15m / min. The embossing roller is a product manufactured by Kyungwon Machinery Co., Ltd., the diameter of the embossing roller 20 inches, embossing roller The width of is preferably about 62 inches. However, in the present invention, the embossing processing conditions are not particularly limited.

When the uneven pattern is repeated in a state separated from each other as shown in FIG. 9, it is more preferable that the spacing between the uneven patterns adjacent to each other is 2 to 20 mm to improve aesthetics and shape stability.

On the other hand, if the uneven pattern is repeated with each other as shown in Figure 8, the maximum spacing between the lines forming one uneven pattern, that is, the maximum width of the uneven pattern is 2 ~ 20㎜ aesthetics and shape It is preferable for improving stability.

As the fabric of the present invention as described above, irregularities are formed on the surface and / or the back to improve the aesthetics and at the same time firmly hold the tissue point of the fabric is good morphological stability of the tissue.

On the other hand, the fabric of the present invention is more preferably surface-treated with a friction material in order to improve the aesthetics and feel.

The surface treatment may be performed by rubbing the surface of the fabric with a roller, a disc or an apron attached to a friction material such as fabric, knitted fabric, nonwoven fabric, leather, sandpaper, needle cloth, ceramic material, metal, paper, and wood.

Surface treatment with a friction material, the microfibers (single-fiber fibrill) of the fabric of the present invention receives not only the external force in the direction parallel to the inclination but also the external force in the direction perpendicular to the inclination, so that the microfibers are unbalanced and distributed as a weft yarn assembly in the fabric. Single yarn fibrils are dispersed / diffused / re-aggregated so that they are evenly distributed throughout the fabric.

Dispersion / diffusion / re-aggregation of this series of microfibers (single-fibrils) fills the space where the microfibers (single-fibrils) are not filled in the fabric before the surface processing, and the average space in the fabric is more The volume is increased and the volume is improved. This improves touch and also provides space for collecting contaminants.

Will be expanded. In addition, microfibers (single-fiber fibrils) are entangled with each other during the dispersion / diffusion / reaggregation process, and have sufficient form stability against external force applied to the fabric.

This fact becomes even more apparent when comparing FIG. 10 and FIG. 12 or FIG. 11 and FIG.

FIG. 10 is an electron micrograph showing the surface state of the uneven pattern formed part of the fabric which is not subjected to the surface processing after the uneven processing as shown in FIG. 8, and FIG. 11 is not formed of the uneven pattern of the fabric not subjected to the surface treatment. Electron micrograph showing the surface state of the part not.

12 is an electron micrograph showing a state in which the fabric portion of FIG. 10 is surface processed, and FIG. 13 is an electron micrograph showing a state in which the fabric portion of FIG. 11 is surface processed.

As a preferable example, the island component constituting the island-in-the-sea composite yarn is polyethylene terephthalate, and the sea component is preferably copolyester copolymerized with 1 to 10 mol% sodium dimethylene sulfoisophthalate.

The split composite yarn is a structure in which the eluting component and the fiber forming component are formed in a wedge shape or the like, and it is preferable that polyamide is used as the eluting component and polyester is used as the fiber forming component. Such split type composite yarn is eluted by alkaline aqueous solution treatment, and the polyester, which is a fiber-forming component, is separated from each other to become ultrafine yarn.

In the above weaving, the tissue may be plain weave, runner or twill.

In the present invention, the woven fabric may be eluted or divided and then dyed after scouring in an aqueous alkali solution, or the woven fabric may be dyed immediately after scouring the woven fabric and then eluted or divided.

In general, when producing a suede knitted fabric using a two-component composite yarn, a high shrinkable yarn is used together with a two-component composite yarn to give a thickness to the fabric.

However, in the present invention, since the fabric is made only of two-component composite yarns without using high shrinkable yarns together, the fabrics are subjected to heat treatment and post-heat treatment at 120 to 160 ° C. before and after dyeing to give a thickness to the fabrics. It is desirable to generate crimps due to shrinkage, and to reduce the alkali (elution or splitting of the sea component) to 28 to 38% by weight of the total weight.
