本発明は深色に染色されたジーンズの脱色方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for decolorizing jeans dyed in a deep color.

研摩石も使われている様である。<Prior art> For example, in recent years, it has been possible to completely or partially bleach clothes or bags made from fabrics dyed in indigo colors, such as jeans dyed blue, green, or red. . The polishing stone used in this method is conventionally a natural pumice stone, and the color is removed by kneading the natural pumice impregnated with a bleaching agent in a tank that is included with the jeans. In some cases, plastic abrasive stones are also used.

等である。なお軽石内部の保有水分を乾燥除去するのは
非常に手間と時間を要するのである。<Problems to be solved by the invention> Among the conventional methods described above, the method using natural pumice has a large amount of abrasion of the polishing stone, generates a large amount of sludge, and its discharge treatment is complicated. At the same time, the sludge gets into the pockets of pants, etc., and it is troublesome to take it out, and of course, the worn bones must be replenished. Also, since it is a natural pumice stone, its quality varies widely, and it is difficult to control when decolorizing it, so it is necessary to change the conditions each time taking into account the characteristics of the pumice stone at that time. For example, if the humidity is high, not only will the absorption of the bleaching agent be poor, but also moisture will be stored inside the pumice stone, making it impossible to maintain the desired concentration of the bleaching agent. It is noted that drying and removing the moisture retained inside pumice requires a great deal of effort and time.
また一部で実施されているプラスチック製研磨石を用い
る方法は、気孔が不均一で脱色剤の吸着保有能力が低い
ので脱色の仕上がりがよくない。In addition, the method of using plastic polishing stones, which is practiced in some places, has uneven pores and has a low ability to adsorb and hold decolorants, resulting in poor decolorization results.

う方法である。Means for Solving the Problems> The above object of the present invention can be achieved by adopting the following means. That is, as a method for producing abrasive stones, a mixture of 5 to 30 parts by weight of glass frit added to 100 parts by weight of silica sand is kneaded, and then 15 to 40 parts by weight of water is added and mixed.
Furthermore, 2 to 10 parts by weight of carboxymethyl cellulose is added and mixed until it becomes sufficiently sticky, and the mixture is pressure-molded, then dried and fired. A porous abrasive stone obtained by firing a mixture containing silica sand as a main component and glass frit added thereto, and an aqueous bleach solution are placed in the tank provided.
After fully impregnating the porous abrasive stone with the bleach aqueous solution, the remaining bleach aqueous solution is drained, and the bleach absorbent is sprayed.Then, the dyed jeans are placed in the tank, the tank is rotated, and then the jeans are removed. In this method, the sample is taken out, washed with water, and neutralized.

３０重量部を越えると気孔率が低下し目的とする多孔質
体が得られないからである。Here, 5 parts of glass frit is added to 100 parts by weight of silica sand.
The reason for adding ~30 parts by weight is that if it is less than 5 parts by weight, it will not be possible to fire unless it is fired at a very high temperature, whereas if it exceeds 30 parts by weight, the porosity will decrease and the desired porous body will not be obtained. This is because it cannot be done.

パリを除去する様にする。Within the range of the method of the present invention, it can be fired at a temperature of about 900 to 980°C, has sufficient wear resistance, and has a porosity of approximately 20 to 50%, so it can be used as a polishing stone for washing. fully demonstrate its function. Carboxymethyl cellulose is a substance that keeps the mixed powder in the desired shape when it is in use.If it is less than 2 parts by weight, it has no effect, and even if it is added in a large amount exceeding 10 parts by weight, the effect will hardly change. In addition, there is a problem that it remains in the fired body and reduces the wear resistance of the fired body or becomes a cause of deterioration, so the limit is set at 10 parts by weight. Since the raw molded body before firing often has burr during molding, this burr is removed using a mixer.

行う。It goes without saying that the porous abrasive stone produced by the method of the present invention, which has silica sand as its main component, can be used in the so-called stone wash method, which is a method of decolorizing jeans by bringing only the abrasive stone into contact with the jeans. However, the so-called chemical wash method allows you to take full advantage of the porous nature of this abrasive stone. The jeans wash of the present invention is also a type of chemical wash method, in which hypochlorite soda, for example, is used as the bleaching agent.
A bleach absorber is also used to remove wetness from the surface of the polishing stone and make the decoloring effect uniform. The concentration of bleach and the amount of bleach absorbent used are determined by the color and degree of dyeing of the jeans, as well as the degree of bleaching. After decolorization, neutralization treatment is performed.

Since the abrasive stone is poured into the abrasive stone and stirred, the aqueous bleach solution impregnated into the pores of the abrasive stone gradually comes out to the surface, effectively decolorizing the jeans.
〈実施例〉 以下本発明をその実施例を示し乍ら詳述する。<Example> Hereinafter, the present invention will be described in detail while showing examples thereof.

判った。In this Example 2, 40 abrasive stones obtained in Example 1 above were placed in a horizontal cylindrical tank measuring 1400 mmφ x 1300 mm wide.
Pour in the mausoleum, swirl for 10 minutes, then add 100 ml of sodium hypochlorite solution! and water 1002, left for 2 minutes, opened the drain hole at the bottom of the tank, and drained the sodium hypochlorite aqueous solution. Next, sodium sulfate powder was evenly spread over the surface of the abrasive stone, 10 jeans pants dyed blue with indigo were placed, and the tank was rotated at 20-25 rpm for about 20 minutes. Next, the jeans pants were taken out of the tank, washed in a horizontal washing tank of approximately the same shape and size as the decolorizing tank, which can rotate freely, and then neutralized with a neutralizing agent made by adding hydrogen peroxide to sodium carbonate. Washed with water, dehydrated, and dried. The resulting pants were effectively and evenly bleached to a whitish color. It should be noted that there was still some ground material of the abrasive stones in the decolorizing tank, and as a result of examining the weight of the remaining abrasive stones, it was found that about 1% by weight was ground in one operation.
従って、上記操作を１０回繰返す（但し最初のから回し
は２回目以降は不要）毎に、約４ ｋｇ位の研摩石を補
充すればよい事となる。Therefore, it is sufficient to replenish approximately 4 kg of abrasive stones every time the above operation is repeated 10 times (however, the first rounding is unnecessary from the second time onwards).

択できる。<Effects of the Invention> As described above, the method for producing an abrasive stone of the present invention is clean, wear-resistant, and porous abrasive stone can be obtained with high reproducibility. The method of washing jeans using abrasive stones is that the abrasive stones have a three-dimensional ceramic structure with uniform communication holes, have high liquid absorption properties, have a large capacity to retain decolorants, and are also highly abrasion resistant. Because of its excellent properties, it is highly durable, and since only a small amount of ground material is generated, post-processing is easy. Furthermore, the reproducibility of the decolorizing effect is good in chemical washes under the same conditions, and the finish can be arbitrarily selected by changing the conditions.
従ってジーンズウォッシュ工場の安定した行程。Hence the stable process of the jeans wash factory.
品質管理が容易になり、また自動化操業にもつながる。This makes quality control easier and also leads to automated operations.
