In addition, the use of dangerous chemicals is difficult to handle, requires knowledge of chemicals and skill in work, and requires a large amount of water and chemicals, drainage affects the environment, and batch processing is possible. However, there was a problem that continuous processing was impossible.

However, when ozone is dissolved in water, large bubbles composed of ozone and oxygen or air are formed, and these bubbles immediately rise. Since ozone disappeared into the atmosphere, the time during which ozone stayed in water was short, and the objectives could hardly be achieved. Further, the fabric is wound in a multilayer structure on a cylinder made of a perforated plate and placed in a tank, and an ozone solution having an ozone concentration of about 15 mg / liter is passed from the inside of the cylinder in the radial direction of the rolled fabric wound in the multilayer structure. Although a method (see Japanese Patent Application Laid-Open No. Hei 7-11565) is known, even in this case, even though the ozone concentration is low and effective for improving bleaching and pilling properties, a fiber modification comparable to kneading can be performed. It could not be performed and was unsuitable for continuous processing.

It is possible to continuously process long fibers in the form of tows, yarns, woven fabrics, knits, etc. and carry out fiber modification processing comparable to kneading at several times the speed of conventional kneading.

However, the generated ozone concentration in air or oxygen is preferably 58 g / m 3 (29000 ppm) or more. If the generated ozone concentration is lower than this, it becomes difficult to bring the ozone concentration in the ozone water to a desired concentration, and the fiber It is unsuitable for use as a material for reforming.

In the present invention, ozone water having an ozone-containing bubble diameter of 0.08 mm or less is used. For this purpose, ozone immediately after generation is introduced into the water together with air or oxygen, and large ozone-containing bubbles generated in the water are carried in a water stream and collide with projections or baffles to break them into fine bubbles, which are then brought into the water. It is preferable to perform uniform dispersion.

ことが困難になり、目的の達成が困難になる。In the present invention, the fibers are immersed in the above-mentioned ozone water in the form of tows, yarns, woven fabrics, knits and the like. This immersion
Either a batch type or a continuous type may be used, but a continuous type in which the immersion treatment tank is filled with ozone water and the long fiber is immersed in the ozone water while being renewed and transferred in one direction is advantageous. Then, the fiber is treated with ozone in water during the immersion, but since ozone is dissolved in water as fine bubbles together with air and oxygen, ozone stays in water for a relatively long time, and the ozone The ozone concentration is maintained at a high level, so that the ozone effectively acts on the immersed fibers, whereby the fibers are fibrillated and softened in a shorter time than conventional kneading. However, when the diameter of the ozone-containing bubbles is large and exceeds 0.08 mm, the residence time of the ozone-containing bubbles in water is short, and it is difficult to maintain the ozone concentration at a high level of 35 mg / liter or more as described in claim 2. And it becomes difficult to achieve the purpose.

Thereafter, it can be introduced into the above immersion treatment tank. In this case, once the fibers are immersed in warm water, the dried fibers are not immersed in the immersion treatment tank, so that it is possible to prevent bubbles from coming into contact with the dried fibers and being repelled. Also, by cooling with cold water of about room temperature after immersion in warm water, the temperature of ozone water in the immersion treatment tank can be prevented from rising, and ozone can be kept at a high concentration.

A change appears on the surface of the fabric F in 10 minutes, fibrillation starts in 15 minutes of immersion, and breakage of a part of the fiber structure occurs in 20 minutes of immersion, which is caused by a conventional general modification using enzymes. It was almost the same as the destruction caused by the quality processing. That is, the required time was reduced to 1/10 or less from the conventional 4 to 5 hours. When the diameter of the bubble is about 0.5 mm, ozone is easily scattered.

害物質が全く発生しない。As described above, according to the first to third aspects of the present invention, the fibers are fibrillated by ozone treatment in the form of a tow, a thread, a woven fabric, a knitted fabric, or the like. Modification processing at the same level as processing can be performed, and the required time is greatly shortened compared to conventional processing, and continuity is possible. In addition, ozone disappears into the atmosphere and becomes oxygen, generating harmful substances at all do not do.

The above-mentioned reforming can be performed more efficiently. According to the third aspect of the present invention, since the contact between the fiber and ozone is improved and the temperature of the ozone water is prevented from rising, it is possible to prevent ozone from disappearing early.
