  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
In the present embodiment, bamboo vinegar liquid obtained by collecting and cooling the flue gas emitted when producing bamboo charcoal is used. And the liquid obtained by refine | purifying with a low-temperature distillation method or a stationary method is made into a bamboo vinegar solution of Ph3.0-5.0, and is diluted and left until it becomes an odorless state. Bamboo charcoal is baked at approximately 900 to 1000 degrees, and the bamboo vinegar liquid produced at 80 to 150 degrees in the smoke vent is left stationary, and the collected yellow-brown liquid (stock solution) is static for about half a year to one year. Put. Bamboo growing within 4 to 5 years is more effective for producing bamboo charcoal.
The bamboo vinegar thus obtained is separated into a liquid layer in which water-soluble tar is precipitated and a highly transparent liquid layer, so the supernatant (transparent part) is taken out from the middle layer and separated by filtration. You can make things close, but cool them. The dilution ratio was diluted 50 to 80 times using distilled water (bamboo vinegar of Example 1).

In addition, the bamboo extract obtained by boiling bamboo and bamboo was cooled and diluted. Add water to the kettle and boil the bamboo and bamboo at 100 ° C. The green bamboo is preferably just after logging. When boiling bamboo and bamboo shoots, components on the surface of bamboo can be extracted and a bamboo extract of Ph 5.0 to 5.5 can be obtained. This was adjusted to pH with acidic water and allowed to stand and diluted until it became odorless to produce a bamboo bamboo extract with a pH of 3.0 to 5.0.
The time for standing still is about 3 to 5 days (green bamboo extract of Example 2). It should be noted that no caustic sadder is used for boiling. In addition, Iwakawa Miso bamboo just after logging was used. Wakatake that grew within the current year or one year is more effective for producing bamboo extract.

Using the bamboo vinegar of Example 1 and the green bamboo extract of Example 2, a Japanese paper fiber fabric (raw cloth) was processed in the scouring dyeing preparation step S1, the dyeing step S2, and / or the finishing step S3. .
Washi made from Japanese paper is made from manila hemp as a raw material and is made up into Japanese paper to be broken down into fibers. Japanese paper is a natural material composed of plant cellulose, and this Japanese paper was fixed to a thread that was not twisted and could not be dissolved in water. Japanese paper thread is made by weaving a special Japanese paper cut into a tape shape with a width of about 1mm to 30mm as it is, so it is very light compared to twisted Japanese paper and cotton thread, and it features smoothness with no fluff on the surface. is there.
This Japanese paper thread was dipped in a container containing the bamboo vinegar solution of Example 1 and the green bamboo extract of Example 2 and applied. When weaving with a loom, it is possible to pass a Japanese paper thread through a tank to produce a woven fabric, or to apply the finished thread to the finished thread in a post-coating process.
The Japanese paper thread is excellent in hygroscopicity, but is manufactured by mixing with recycled fiber or natural fiber in order to obtain the strength as a thread. It may be combined with a hygroscopic yarn such as rayon yarn. For example, Japanese paper 20-50 wt% and recycled fiber 50-80 wt%.

The fiber fabric (raw fabric) is usually manufactured through a dyeing preparation step S1, a dyeing S2, and a finishing step S3 (FIG. 1). Scouring is one of the preparation steps S1 and is performed for the purpose of removing factors that hinder the work of dyeing and finishing, or that impair the finish of the product. This is a process to remove fat, oil, oil, pectin, glue, etc. adhering to the fiber. Although it depends on the type of fiber, in general, an appropriate surfactant is added to an alkaline aqueous solution for the purpose of shortening the scouring time, and heating is performed together with the fiber. In this embodiment, in the dyeing preparation step S1, the bamboo vinegar solution of Example 1 is added, the bamboo shoot extract of Example 2 is added, or the bamboo vinegar solution and the bamboo shoot extract of Example 3 are mixed. The liquid (Example 3) is added (mixed in a 1: 1 ratio) and used in the above processing steps. All are applied by dipping.
In the preparatory step, Example 1 and Example 2 were used instead of the conventional scouring processing agent, and applied by immersing in the fiber fabric. Here, hot water was washed first, and Example 1 and Example 2 and Example 3 in which these were mixed were used. Since the bamboo extract of Example 2 has a function as an oil adsorbent, a synergistic effect with the bamboo vinegar of Example 1 is achieved. That is, using the bamboo extract of Example 2, as a result of special processing, it was proved in the inspection that almost no harmful substances such as free formaldehyde were detected (Attachment Table 1), towel, stall, clothes It has become possible to manufacture clothing, such as fabrics, sheets, and hats, and medical equipment-related products that emphasize hygiene such as antibacterial properties. In addition, because it has the property of absorbing radioactive toxic substances such as radioactive cesium and iodine, it is effective for the treatment of pollutants by filtering radioactive polluted water, and incineration is easy to concentrate and reduces the mass and processing costs during storage. You can expect to contribute. And when mixed with the bamboo vinegar of Example 1 above, a synergistic effect was obtained such as absorbing the smell of bamboo extract and allowing the bamboo vinegar to be stored for a long period of time.

  As shown in Table 1, in JIS L1041 according to Example 2 above, 0.05A-A0 or less was shown for baby underwear and the like, but the measured value of the fabric product of the present embodiment was an extremely low value of 0.01.

  In this embodiment, it was inspected whether or not it has antibacterial properties. Table 2 is a test of the bacteriostatic activity value determined by the Japan Fiber Evaluation Technology Council. When the product of Example 1 was satisfied with a bacteriostatic activity value ≧ 2.2, the bacteriostatic activity value ≧ 3.1 was shown (Table 2). On the other hand, the bacteriostatic activity value was lower than the standard value for those not processed with the bamboo vinegar solution of the example. In addition, the deodorization test was verified by human sense of smell, but no off-flavor was felt. Further, the bacteriostatic activity value was 0.2 in the 10th processed product (SEK standard washing method) (Table 2). In Table 2, the client, Tokai Chemical Co., Ltd., is a joint developer with the present applicant, and the sample cloth in Table 2 is attached with a raw fabric (a fiber fabric made of Japanese paper of the embodiment). It is a thing.

  Next, the bamboo bamboo extract of Example 2 was added in the dyeing step S2. Dyeing is a technique for fixing a dye to a fiber or the like by utilizing the dyeing property of a dye to a fiber material. In general, dyes are diffused in the form of molecules as an aqueous solution, and then fixed on the fibers with a specific affinity (dyeability) for the dye fibers. In this embodiment, the bamboo bamboo extract of Example 2 was added, but the bamboo vinegar of Example 1 was added to the dye, or the bamboo bamboo extract of Example 2 was mixed 1: 1. May be used in the dyeing process.

  The above-mentioned Japanese paper fiber fabric (raw fabric) was verified for texture and fastness (color fading) (Table 2). These were judged by human senses by tactile sensation and rubbing (friction). The comparison object is a comparison with a Japanese paper fiber product manufactured without using Examples 1 to 3 (the conventional scouring agent and dye were used as they were), and the texture and fastness were high (color fading). A case where both were good was marked as ◎, and a case where only one of them was good was marked as ○. From this result, it can be seen that the bamboo vinegar of Example 1 may be used in the refining preparation process, and Examples 2 and 3 may be used in the dyeing process. In addition, the result of 2 uses Example 1-3 in each process (S1-S3), respectively, The overlapping use is not performed.

  As described above, the present embodiment has been described using the example of the Japanese paper thread and the Japanese paper fiber product, but the present invention can also be applied to non-Japanese paper thread and fiber products. Moreover, although not used in the present embodiment, when a yarn or fiber fabric using paper made using bamboo fiber is used, the bamboo vinegar of the present invention and the green bamboo extract are also better matched It is thought that sex can occur.
