を引き起こすおそれは解消する。The specific water was produced by applying an electrostatic voltage to approximately neutral water (industrial water, etc.). It is something. The electrostatic voltage may be applied, for example, to substantially neutral water stored in a tank from an electrode. The applied electrostatic voltage is usually about 8000 volts or more, and the application time is usually 18 to 24 hours. By applying such an electrostatic voltage, the number of hydroxide ions increases and ionized fecal water is slightly alkaline (approximately 7.5 to 7.8 per day). In the process, chloride is also decomposed and removed. According to the enzyme treatment process using fecal water, chloride is less likely to enter the jeans material, and as a result, the amount of chloride remaining in the final product is reduced. Therefore, the possibility of yellowing of the product and the risk of causing skin disorders is eliminated.

酵素処理工程の具体的な操作の代表例をより詳しく次に
説明する。A representative example of a specific operation of the enzyme treatment step will be described in more detail below.

．． Tender fecal water adjusted to about 5 to a washing machine (such as a large industrial washing machine). The temperature of the fecal water is set to a temperature suitable for increasing the activity of fibrinolytic enzymes before or after the fecal water is introduced into the washing machine.
次に、温度調整された便化水中に繊維素分解酵素を混入

ＨＮ−１０の場合も含めて一般に、ジーンズ素材１００
重量部に対して、１〜５重量部程度とする。Next, a fibrinolytic enzyme is mixed into the temperature-controlled fecal water. The amount of fibrinolytic enzyme is determined by the above N0VATEX-T.
In general, jeans material 100, including the case of HN-10.
The amount is approximately 1 to 5 parts by weight.

うして、ジーンズ素材表面の毛先を分解して、艶を出し
たり風合いを変化させる。Jeans, jeans skirts, and other jeans materials are placed in a washing machine filled with washing water adjusted in this manner. Next, the jeans material is subjected to enzyme treatment by operating a washing machine containing washing water and the jeans material. In this way, the hair ends on the surface of the jeans material are broken down, giving it a shine and changing its texture.
この酵素処理は、ジーンズ素材が３〜７重量％程度、減
量するまで実施するのが好ましい。減量がこれ以下であ
ると、表面改質の効果が充分でなく、これ以上であると
、ジーンズ素材の強度が低下するためである。This enzyme treatment is preferably carried out until the jeans material loses about 3 to 7% by weight. If the weight loss is less than this, the effect of surface modification will not be sufficient, and if it is more than this, the strength of the jeans material will decrease.

素処理工程でのジーンズ素材が同様な外観になったら、
酵素処理工程を終了すればよい。Incidentally, the end point of this enzyme treatment step can be simply determined in the following manner, for example. A preliminary enzyme treatment experiment was conducted on a smaller scale than the actual enzyme treatment process, with various cleaning treatment times, and the jeans material, which had been reduced to around the target weight, was used as reference material for comparison. When the jeans material has a similar appearance after the enzyme treatment process,
It is sufficient to complete the enzyme treatment step.
上記酵素処理工程を終えたら、その処理がなされたジー
ンズ素材を、繊維素分解酵素の入っていない弱アルカリ
性の優化水ですすぐ。即ち、リンス工程（工程３）を実
施する。After completing the above enzyme treatment process, the treated jeans material is rinsed with mildly alkaline enriched water that does not contain fibrinolytic enzymes. That is, a rinsing step (step 3) is performed.
このリンス工程の操作は例えば次のようである。The operation of this rinsing process is, for example, as follows.

ンスの時間は１５〜３０分間程度とする。The washing water contaminated with the fibrinolytic enzyme used in the enzyme treatment process is drained from the washing machine, and freshly purified water is then rinsed with the purified water. The temperature of the enriched water depends on the type of enzyme used in the step, but the temperature of the enriched water depends on the type of enzyme used in the above step.
In general, the temperature should be around 50°C, including the case of 0 (7), and the rinsing time should be about 15 to 30 minutes.

優化水にて、もう１度２０〜３０’Ｃでリンスすれば、
繊維素分解酵素のより充分な失活を図ることができる。In this rinsing step, the P of the enriched water is weakly alkanoic, so the fibrinolytic enzyme is inactivated and the fibrinolytic enzyme is removed. In addition, at the final stage of the rinsing process, if you rinse once again at 20-30'C with new enriched water,
More sufficient deactivation of fibrinolytic enzymes can be achieved.
以上説明したリンス工程では、繊維素分解酵素の失活の
ために従来使用していたアルカリ剤を使用していない。In the rinsing step described above, the alkaline agent conventionally used to deactivate fibrinolytic enzymes is not used.
またジーンズ素材をかなり高温（９０°Ｃ程度）に温度
上昇することも行っていない。Also, the temperature of the jeans material is not raised to a fairly high temperature (about 90°C).
アルカリ剤が使用されていないため、最終ジーンズ製品

、水和による湿った感触となったりする間実は生じない
。しかも、中和剤を用いたアルカリ剤の中和工程も当然
不要であるため、中和工程による工程数の増加や中和剤
使用によるコスト上昇が起きない。Since no alkaline agents are used, there is no chance of residual alkaline agents remaining in the final jeans product.Therefore, there is no chance that alkaline agents will cause jeans products to harden, become brittle, or have a damp feel due to hydration. Moreover, since the neutralization step of an alkaline agent using a neutralizing agent is naturally unnecessary, the number of steps due to the neutralization step does not increase, and the cost does not increase due to the use of the neutralizing agent.
また、繊維素分解酵素を失活する目的での温度上昇が不
要なために、燃料や製造時間をロスしない。Furthermore, since there is no need to raise the temperature to deactivate fibrinolytic enzymes, there is no loss of fuel or production time.
上記リンス工程の後に、必要に応じて各種の仕上げ剤を
用いて仕上げ処理工程を実施する（工程４）。例えば、
ジーンズ素材の柔軟性をより向上するために、カチオン

性の良い柔軟性のあるジーンズ製品が製造できる。On the other hand, in Example 1 according to the present invention, since no alkaline agent remained in the gins, it felt soft to the touch, and no embrittlement due to alkali was observed even after being left for a long period of time. In addition, in Comparative Example 2, when the residual chloride was measured, it was about 18 ppm for both the first and second times.
Since the temperature was raised to 0°C, fuel loss was greater than in Example 1, and the manufacturing time was 45 minutes longer than in Example 1. Effects of the Invention As detailed above, according to the method for manufacturing jeans products of the present invention, the weak alkalinity is improved in the rinsing step after the enzyme treatment step. Since water is used to deactivate the fibrinolytic enzyme, there is no possibility that the alkaline agents used in the past will remain in the jeans. Therefore, even without performing a neutralization step, it is possible to produce jeans products that do not experience any wet feel, brittleness, or hardening caused by alkaline agents, that is, flexible jeans products that have good texture and good water absorption.
