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.                         

On the other hand, Japanese Laid-Open Patent Publication No. 2002-153406 proposes a wiping fabric having a single yarn fineness of 0.001 to 0.1 dtex of warp and weft yarns using a split composite yarn or its air-texturing yarn as warp and weft yarns.

However, the above method has a problem that the touch is hard and the risk of damaging the surface of the decontamination object is used because the divided composite yarn is used as the warp and weft yarns.

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.

Contaminant-removing polyester fabric of the present invention for achieving the above object is a polyester multifilament made of polyester ultrafine yarns of 0.001 to 0.1 deniers or its twisted yarns thereof, the warp density of the ultrafine yarns 100,000 to 1,500,000 to 1,500,000 tons per inch, the weft density of the ultra-fine yarn is 50,000 to 550,000 tons per inch, characterized in that the uneven pattern by embossing is formed on any one or more of the front and back surface of the fabric. It is done.

In addition, the present invention is a polyester multifilament made of island-in-sea and sea-component after the sea component eluted (single-fibrils) single-core fineness of 0.001 to 0.1 denier islands-like composite yarn or its flammable processed yarn is inclined and weft Weaving the fabrics, refining the woven fabrics in an aqueous alkali solution and eluting the seaweeds at the same time, then dyeing or dyeing the woven fabrics, and then eluting the seaweeds in the alkaline aqueous solution. Embossing process to prepare a polyester fabric for removing contaminants.

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

Polyester multifilament made of polyester super microfibers (single yarn fibrils) of 0.001 to 0.1 denier or its warp yarns constituting the pollutant-removing polyester fabric (hereinafter abbreviated as "fabric of the present invention") Combustible work.

It is more preferable that the fineness of the said polyester ultra-microfiber (single-fiber fibrils) is 0.05-0.005 denier.

The inclined density of the ultrafine yarns is 100,000 to 1,500,000 tons per inch, and the weft density of the ultrafine yarns is to 50,000 tons to 550,000 tons per inch.

If 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 a long period of time. Problems may also arise that are difficult and increase the manufacturing cost.

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. Accordingly, the fabric tissue of the present invention is a plain weave or twill, or a tissue in which a plain weave or twill weave and a pattern forming tissue of the weave 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.

As a warp and / or weft, polyester multifilaments made of the ultrafine yarns described above, that is, yarns that are not twisted or treated after spinning and stretching, can be used, but the warp and weft are prevented from slipping each other on the fabric structure. In order to further improve the dirt removal performance, it is more preferable to use a twisted yarn manufactured by twisting the polyester multifilament as warp and / or weft yarn.

Specifically, it is preferable to use the twisted yarn as the warp yarn and the polyester multifilament which 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 the island-in-the-sea composite yarn in the same process as FIG.

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

The uneven pattern is formed by embossing.

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 25 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 ~ 25㎜ 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 The single yarn fibrils are dispersed / diffused / reaggregated so that they are evenly distributed throughout the entire space of 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 the feel and expands the space for collecting contaminants. 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.

Fabric for removing contaminants of the present invention described above is composed of ultra-fine yarns (single fibrils) of warp and weft yarn of 0.001 ~ 0.1 denier can effectively collect fine contaminants by the fine pores formed between them, the touch is smooth and appearance It is excellent and does not damage the surface of the dirt removal object.                     

Furthermore, the contaminant removing fabric of the present invention has an uneven pattern formed by embossing on its surface and / or its back surface, so that it has excellent aesthetics and shape stability, and when its surface is surface-treated with friction material, it has an aesthetic and soft touch. This is further improved. Next look at in detail the method of manufacturing the fabric of the present invention.

The island component constituting the island-in-the-sea composite yarn is polyethylene terephthalate, and the sea component is a copolymerized polyester obtained by copolymerizing 1-10 mol% of sodium dimethylene sulfoisophthalate. In the weaving, the tissue may be plain or twill.

In the present invention, the woven fabric may be eluted at the same time as elution of the sea component in an aqueous alkali solution, and then dyed, or the fabric may be dyed immediately after the woven fabric is rinsed and then eluted.

In general, when manufacturing a suede-like knitted fabric using an island-in-the-sea composite yarn, a highly shrinkable yarn is used together with the island-in-the-sea composite yarn to give a thickness to the fabric.                     

However, in the present invention, since the fabric is produced only by the island-in-the-sea composite yarn without using high shrinkable yarns together, the fabric is preheated and post-heated at 120 to 160 ° C. before and after dyeing in order to give the fabric a sense of thickness. It is preferable to generate crimps due to shrinkage, and to reduce alkali (elution of sea component) to 28 to 38% by weight of the total weight.

1 is a photograph showing the surface state of the fabric of the present invention immediately after the weight loss process.

Next, the fabric, which has been dyed and reduced (reduced and dyed), is embossed (uneven) by a concavo-convex machine to form concavo-convex patterns on the surface, the back side, or both the front and back side of the fabric to form stability and aesthetics of the fabric. Improve.

By the embossing treatment, the tissue points on the fabric are firmly fixed to each other by fusion or the like to improve the shape stability of the fabric.
