理が問題となる。Although it is known in the prior art that ozone has a strong bleaching action, there is no method for decolorizing a textile dyeing product by actively using ozone. Rather, efforts have been made to reduce the ozone fading of dyed textiles as seen in JP-A-63-309680. Conventionally, as a decolorizing agent used for partial decoloring of jeans, there are active chlorine bleaching agents such as hypochlorite, chlorite, bleaching powder, and cyanuric acid chloride bleaching agents.
In addition, there are oxidative bleaching agents such as permanganate, hydrogen peroxide solution, sodium peroxide, sodium perborate, and barium peroxide. There are also reducing bleaches such as hydrosulfite. However, there is a problem that fiber dyeings (including jeans) dyed with a slen dye are fast and are difficult to be decolorized by the above conventional decolorizing agents. On the other hand, as a method for partially decolorizing jeans using the above decolorizing agent, there are a stone wash method, a chemical wash method, a bleach method and the like. In the stone wash method, twill weave blue jeans and pumice stone are stirred and contacted in a device such as a washer, and a colored portion is removed by frictional force to partially remove the color. In the chemical wash method, twill weave blue jeans and pumice impregnated with a bleaching agent solution such as sodium hypochlorite are agitated and contacted in a device such as a washer to partially decolorize. The mechanism of this partial bleaching is that when the pumice stone containing the bleaching agent comes into contact with the twill weave blue jeans fabric, part of the impregnated bleaching agent moves from the pumice stone to the jeans and decomposes and decolorizes the dye in this part. is there. In both the stone wash method and the chemical wash method, the bleaching pattern is a so-called stirring contact bleaching pattern (a hitting pattern) in which a portion that is in good contact with pumice stone is well bleached, and a portion that is less in contact is less bleaching.
However, the part with less contact with pumice stone also has some decolorization, and the color contrast between the contact part and the non-contact part is not so remarkable. Further, since these agitated contact decolorization pattern products have been on the market for many years, they are becoming products lacking in freshness, and the development of new decolorization patterns is an issue. Further, in these stone wash method and chemical wash method, since the cloth is rubbed with pumice, embrittlement of the cloth also becomes a problem. On the other hand, the bleach method is a method in which jeans and a large amount of a bleaching agent such as sodium hypochlorite are stirred in a device such as a washer to decolorize, and all parts are decolorized almost uniformly. This is also a kind of bleaching pattern and has been commercialized, but it is not the above stirring contact bleaching pattern (contact pattern). Furthermore, since the above-mentioned decolorizing agent is used in a large amount of liquid at the time of processing, its waste liquid processing becomes a problem.

That is, facilitating the partial decolorization of dyed products dyed with all dyes including slene dyes, and in jeans of the stone wash method and chemical wash method, there is little contrast in the agitation contact decolorization pattern (hit pattern), This solution solves the problem that it is not interesting and that it has been marketed for many years and is becoming a product lacking in freshness.It provides a fresh decolorized pattern completely different from the conventional stirring contact pattern. is there. Further, in these stone wash method and chemical wash method, since the fabric is rubbed with pumice, brittleness of the fabric is also a problem, but this is prevented. Furthermore,
This is a decolorization process that does not pose a problem for waste liquid treatment.

ることもできる。The present invention obtains a bleaching pattern with a bleaching contrast due to a slight difference in the amount of adhering water by exposing it to an ozone atmosphere in a state of containing moisture with a difference in the amount of adhering water to the textile dyed product. And a method for forming a decolorized pattern of a dyed fabric. The method of the present invention will be described in detail below. The fiber dyed product applied to the present invention is a dyed product composed of a woven fabric, a knitted fabric, a non-woven fabric, or the like, and jeans are often used. That is, the conventional partial decolorization technology for dyed products is
As mentioned in the prior art, it has been used especially in jeans. The reason is that a stirring contact decolorization pattern (a hit pattern) can be effectively produced. That is, jeans are twill-woven using thick count dyed yarns as warp yarns and non-dyed yarns as weft yarns, but since only the warp yarns are dyed, this cloth is put in a rotary stirring container with pumice stone and a decolorizing agent liquid. This is because, when the stirring contact treatment is performed in the inside, the contact portion is almost completely decolorized, and a so-called contact decolorization pattern (a hitting pattern) with a color contrast between the decolorized portion and the non-bleached portion appears. If necessary, the fiber dyeing material to be used is pretreated in advance. For jeans, remove wrinkles and desizing. The method is to put a large amount of water inside the product such as pants to pass wrinkles,
The so-called dipping method is also used to remove desizing.
There is a method in which warm water is put into a rotary stirring container such as a drum, washed, and then dehydrated and dried or not dried. Next, in the decoloring step, moisture is applied to the fiber dyed product in advance so that there is a slight difference. The reason for the application is that in the subsequent ozone treatment, the ozone is more decolorized than the portion in which a large amount of water is present is smaller than the portion in which a large amount of water is present. The degree of decolorization after 30 minutes of ozone exposure increases as the water content increases from 0% to 10%, 20%, 30%, 40%, and reaches a maximum at about 50% to 60%, but 70%, 100%, 100
It decreases as it goes above%. Where moisture content is 0%
Is a state in which moisture is not intentionally added, that is, at room temperature,
Equilibrium moisture condition of the line dyed product at normal humidity. Water can be added not only by using pure water but also by adding acid, alkali, or a surfactant. Water can be applied by immersing in water and then squeezing to an appropriate water content, or by spraying water. In addition to the non-uniform method, a conscious design pattern appears. As an example, with jeans, a part that gives a lot of moisture locally,
By making a portion to which a small amount of water is applied, the decolorization pattern (contact pattern) that appears after exposure to ozone can be made to have a more remarkable decolorization contrast than the conventional contact stirring pattern (contact pattern). Moisture can also be applied by applying moisture to the ozone treatment container without performing it on the dyed product. Next, the above-mentioned fiber dyeing product having a different water application amount is put in an exposure container, and ozone is blown into the room to decolorize. The ozone outlet is passed through a potassium iodide solution to decompose ozone. A commercially available ozone generator can be used to generate ozone. For example, Mitsubishi Ozonizer OS-4 type can be used. This ozone generator is a method of silent discharge, air is used as a raw material gas, and the maximum production amount is 4 g / hr, and the production amount is variable in the range of 0 to 100%. Maximum ozoneizer applied voltage is 12
kv, maximum power consumption is 125W / hr, water is used for cooling, and the required water volume is 0.2 liters / min or more. As described above, the decolorizing effect by ozone treatment is affected by water content, but is also affected by the time of ozone treatment. Almost no bleaching occurs when the treatment time is 5 minutes with a water content of 30 to 70%, but there is considerable bleaching in 20 to 30 minutes, intense bleaching in 45 minutes, almost all bleaching in 60 minutes, and complete bleaching in 90 minutes. , Becomes white. In addition, the feature of ozone treatment is that the decolorizing power is strong,
No matter what kind of dye is used for dyeing the fiber in advance, for example, not only direct dyes and sulfur dyes, but also slene dyes and mixed dyes thereof which are difficult to decolorize with conventional decolorizing agents. Even if there is any, it can be easily decolorized. In the decolorized product obtained by the ozone treatment in this way, the gaseous ozone uniformly spreads to each part of the cloth surface, so that the decolorized pattern can have various patterns depending on the water adhesion state of the cloth. As an example, if you create a part with high moisture content and a part with low moisture content in jeans locally, the difference will appear as a difference in decolorization, and the freshness with a more remarkable decolorization contrast than the conventional contact stirring pattern (contact pattern). It becomes a decolorized pattern (hit pattern) with a depth. Furthermore, when water is applied in a design state by spraying, a decolorized product having the pattern can be obtained. Decolorization treatment is performed by soaping with water or a surfactant. The ozone treatment is carried out by subjecting the dyed fabric to any one or more of pumice, a pumice-like solid matter, and a fiber pad in a rotary stirring container in which moisture and ozone are present, by stirring contact treatment,
In addition to the pattern due to the slight difference in the amount of adhering water, a decolorized pattern in which a stirring contact decolorization pattern (a hit pattern) is locally added may be used.

態によって定まる。The feature of the present invention is that, by forming a portion with a large amount of water and a portion with a small amount of water for the dyed textile, the difference appears as a difference in decolorization, and the contact stirring pattern (per hit) by the conventional stone wash or chemical wash Compared with the (pattern), it becomes a fresh decolorized pattern (hit pattern) with more remarkable decolorization contrast. Furthermore, when water is applied in a design state by spraying, a decolorized product having the pattern is obtained. All of these decolorization patterns are determined by the state of water adhesion to the cloth.

ったデザインとなった。Hereinafter, the embodiment of the present invention will be described with reference to specific examples.
The invention is not limited to these examples. Example 1 Black jeans pants (800 g) dyed with a sulfur dye were immersed in water and squeezed with a mangle to a water content of 60% by weight. Next, the pants were suspended in a stainless steel cylindrical container having a diameter of 50 cm and a height of 140 cm, and ozone was blown into the pants while rotating the pants. The ozone outlet was passed through a potassium iodide solution to decompose ozone. Ozone was generated using a Mitsubishi Ozonizer OS-4 type, and a silent discharge method was used under the following conditions: flow rate: 3.0 liter / min, voltage: 100 V, time: 30 min. Then, it was soaped, washed with warm water, softened and dried to obtain a final product. The decolorized product obtained by the ozone treatment in this way is almost completely decolorized in the part where the amount of adhering water seems to be optimum, and the part which seems to be not optimal due to the large amount of adhering water is hardly decolorized. It is a decolorized pattern (hit pattern) with a decolorization contrast more remarkable than before. Therefore, as shown in Comparative Example 1, it is a new fresh bleaching pattern, which is different from the stirring contact bleaching pattern (a hitting pattern) having a weak bleaching contrast of the conventional treatment. Comparative Example 1 50 kg of pumice stone having a diameter of 3 to 10 cm was dipped in an aqueous solution of sodium hypochlorite containing 0.2% of available chlorine for 3 minutes, and drained to remove 40
The liquid content was set to%. Put the pumice stone and 40 kg of black jeans pants made of the same cloth as in Example 2 in the washer,
The mixture was subjected to rotary stirring for 30 minutes to carry out partial decolorization. Then
Jeans pants were washed with water and dechlorinated to obtain products. The product thus obtained had a conventional pattern in which the color contrast between the bleached portion and the non-bleached portion was weak. Example 2 Jeans pants dyed with an indigo dye rope (800 g)
Then, about 50 to 70% by weight of water was applied by spraying in a diagonal streak pattern. Then, the pants were treated under the same ozone exposure apparatus and exposure conditions as in Example 1. The product thus obtained had a design with a decolorizing pattern in a diagonal streak pattern.

い。The decolorized pattern of jeans obtained by the ozone treatment with a slight difference in the amount of adhering water of the present invention is not only the conventional decolorized pattern but also the conventional stirring contact decolorized pattern (a hit pattern) depending on the state of adhering water. In comparison, a decolorized pattern (winning pattern) with a freshness with a remarkable decolorization contrast between the decolorized portion and the non-bleached portion is obtained, and a conscious design can also be obtained. Further, in the present invention, since it is not necessary to rub the fabric with pumice stone, the fabric is less brittle as compared with the conventional stone wash and chemical wash. Furthermore, in the conventional decolorization, since a large amount of decolorizing agent liquid and pumice stone are used during processing, the treatment of the waste liquid and waste pumice stone has been a problem,
In the ozone treatment of the present invention, there is no problem of treating waste liquid and waste pumice.
