[0001]

TECHNICAL FIELD The present invention provides flexibility to refined cellulosic fibers, yarns, woven fabrics, and knitted fabrics, and reduces the “fluffing” of the fiber surface to enhance the sensation of clothing products. The present invention relates to purified cellulose fiber, yarn, woven fabric, knitted fabric and a method for treating the same.

2. Description of the Related Art In general, a woven fabric or a woven fabric made of purified cellulose fiber produced from wood pulp is softened by being subjected to a padding process in warm water and then subjected to a bioprocessing using a fiber-degrading enzyme to "hair" the fiber surface. Adjust the standing position,
It is customary then to wash away the enzyme before it is applied to the production of clothing products. Cellulose fibers are formed by arranging microfibrils in which a large number of cellulose molecules are gathered side by side, and the cellulose itself is the main component (about 3
0 to 50%), which is the most abundant biological resource in nature, and 98% of cotton fibers are composed of cellulose.

In the method of treating the woven fabric made of the above-mentioned purified cellulose fiber in hot water, the fabrics are intertwined with each other in a complicated manner and the "hair buzz" is unevenly formed, and a good clothing product is obtained. It has the drawback that it may not exist. In response to this, registered utility model publication No. 30
No. 05592 divides the interior of the horizontally long porous inner cylinder into a plurality of laterally adjacent small chambers by a porous partition plate, puts the dough into each chamber, and supplies warm water to the outer cylinder to form the inner cylinder. For example, there is disclosed a technical means for performing a burr machining by reciprocally swinging within an angle range of 300 degrees.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, the treatment for treating the woven fabric made of the purified cellulose fiber in hot water is a physical chaffing process, so that a partially untreated portion remains, There is a problem that entanglement of each fabric or non-uniformity of "hairiness" occurs. According to the technical means disclosed in Registered Utility Model Publication No. 3005592,
Although the problems of entanglement of the above-mentioned fabrics and "hairiness" are solved, since the basic treatment is essentially the polishing process, there are still problems such as shrinkage and damage of fibers, discoloration, etc. Since a special processing machine is required, there is a problem that the cost for fiber production increases.

To explain the concept of a water molecule cluster, ordinary water does not exist as a water molecule (H ₂ O) alone.
36 to 37 of these water molecules are held together like a bunch of grapes and exist in a state of being polymerized by a chain. This is commonly referred to as a cluster of water molecules.

For example, as shown in FIG. 5, assuming that a normal water molecule cluster 2 comes into contact with the cellulose fiber 1, the diameter of the cluster 2 becomes relatively large, so that the cluster 2 becomes larger. It is hard to penetrate into the cellulose fiber 1. Therefore, even if an attempt is made to process the cellulose fiber 1 and decompose and remove the impurities 3 contained in the fiber by mixing the fiber-degrading enzyme into the water molecule for biotreatment, the fiber-degrading enzyme itself does not. It is difficult for the biotreatment to proceed normally because it is difficult for the biotreatment to penetrate inside. In addition, 6 has shown the "hair bar" grouped on the surface part of the cellulose fiber 1.

Therefore, the present invention improves the permeability of the fiber-degrading enzyme into the inside of the cellulose fiber, imparts flexibility to the fiber, forms "fluff" less, and evenly forms it as a garment. Purified cellulose fiber with enhanced sensation
It is an object to provide a yarn, a woven fabric, a knitted fabric and a method for treating the same.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, according to claim 1, treated water in which water molecules alone or only a small number of water molecules are polymerized is appropriately heated, and the treated water is added to the treated water. Cellulose fibers, yarns, woven fabrics, and knits are immersed in an aqueous solution prepared by mixing fiber-degrading enzymes for an appropriate time to soften the cellulose fibers, yarns, woven fabrics, and knits by biotreatment and decompose and remove impurities. The purified cellulose fiber, yarn, woven fabric and knitted fabric obtained by the above are provided.

According to the second aspect of the present invention, by treating the water molecules with electromagnetic waves to excite and oscillate the polymerized water molecules, treated water in which water molecules are polymerized alone or only a few water molecules are polymerized is obtained. A fiber-degrading enzyme is mixed into the mixture, and the mixture is heated appropriately to prepare an aqueous solution.
The yarn, the woven fabric, and the knitted fabric are soaked for an appropriate time to soften the cellulose fiber, the yarn, the woven fabric, and the knitted fabric by biotreatment and decompose and remove impurities, and then penetrated into the fiber by washing in warm water. Provided is a method for treating purified cellulose fibers, yarns, woven fabrics, and knits, which removes fiber-degrading enzymes.

In practice, a cluster of water molecules is irradiated with an electromagnetic wave of 4 to 14 μm to obtain treated water in which water molecules alone or only a few water molecules are polymerized. Further, the mixing ratio of the fiber-degrading enzyme to the treated water is set to about 10% by weight, the temperature of the aqueous solution containing the fiber-degrading enzyme is set to 30 to 60 ° C., and the cellulose fiber, the yarn, the woven fabric, and the knitted fabric are added to the aqueous solution. Immersion time 30 minutes to 6
0 minutes.

When the cellulose fiber, yarn, woven fabric, or knitted fabric is dipped in the aqueous solution of the fiber-degrading enzyme prepared as described above, the enzyme adheres to the surface portion of the cellulose fiber, yarn, woven fabric, or knitted fabric to average the “hair bristles”. At the same time as the treatment is performed, a minute portion of the cellulose fiber, thread, woven fabric, or knitted fabric is decomposed by the decomposition action of the enzyme, and water molecules and the fiber-degrading enzyme penetrate into the inside of the cellulose fiber, yarn, woven fabric, or knitted fabric. , Cellulosic fibers, yarns, woven fabrics, and knits by biotreatment are efficiently processed and impurities are decomposed and removed to impart flexibility to the fibers, thereby enhancing the sensation when used as clothing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings. As described above, normal water exists as a cluster in which 36 to 37 water molecules are polymerized by a chain. Therefore, even if this cluster comes into contact with cellulose fibers, yarns, woven fabrics, and knitted fabrics, it penetrates into the cellulose fibers. It is in a difficult state. However, when an electromagnetic wave of 4 to 14 μm is applied to a cluster of water molecules, the polymerized water molecules are excited and vibrated to break the chain, so that the water molecules exist independently or only 3 to 4 water molecules are present. Processed water mainly consisting of small clusters connected by a chain can be obtained.

Therefore, when the water molecules 4 come into contact with the cellulose fibers 1 as shown in FIG. 1, the diameter of the water molecules 4 is much smaller than that of the cluster 2 shown in FIG. Therefore, the water molecules 4 easily penetrate into the cellulose fiber 1. The same applies to treated water mainly composed of small clusters.

Therefore, in this embodiment, first, the water molecules are excited and vibrated by the action of electromagnetic waves to obtain treated water in which the water molecules exist alone or small clusters in which a few water molecules are polymerized, and this treatment is performed. An aqueous solution is prepared by mixing fiber-degrading enzyme with warm water obtained by heating water moderately. The temperature of the hot water is 30 to 60 ° C., and the mixing ratio of the fiber-degrading enzyme to the hot water is about 10% by weight.

Then, the cellulose fiber 1 is dipped in the aqueous solution of the fiber-degrading enzyme prepared as described above for an appropriate time. Then, as shown in FIG. 2, the fiber-degrading enzyme 5 is attached to the surface portion of the cellulose fiber 1 to perform the averaging treatment of the “hair fibers” 6 and, at the same time, the cellulose fiber 1 is decomposed by the degrading action of the fiber-degrading enzyme 5. 3 is decomposed, water molecules 4 and fiber-degrading enzymes 5 permeate into the inside of the cellulose fiber 1 as shown in FIG. 3, and the cellulose fiber 1 is processed by biotreatment and is contained in the fiber 1. The action of decomposing and removing the impurities 3 that have progressed efficiently.

With the action of the fiber-degrading enzyme 5, flexibility is imparted to the fiber, and the fiber-degrading enzyme 5 is added.
Acts to shorten the length of each fiber, so that the "hair buffs" 6 are less likely to project from the fiber surface, and as a result, the treatment for lowering the "hair buffs" 6 on average is performed. The immersion time of the cellulose fiber 1 in the aqueous solution may be experimentally determined, but normally 30 minutes to 60 minutes is suitable.

Since the fiber degrading enzyme 5 starts degrading the cellulose fiber 1 itself after decomposing and removing the impurities 3.
After the immersion treatment of the cellulose fiber 1 in the aqueous solution is finished, the cellulose fiber 1 is washed in warm water heated in advance to 60 to 100 ° C. to remove the fiber-degrading enzyme that has penetrated into the fiber to perform the treatment. finish. The cellulose fibers 1 obtained as shown in FIG. 4 have a “hair bar” 6 averaged in a low state, and there are no impurities inside, so that cellulose fibers having enhanced flexibility can be obtained. In addition, although the said embodiment demonstrated based on the refined cellulose fiber, it can be similarly softened also in the state of the yarn, woven fabric, and knitted fabric of the refined cellulose fiber.

[0018]

As described above, according to the purified cellulose fiber, yarn, woven fabric, and knitted fabric according to the present invention, and the method for treating the same, the cellulose fiber, yarn, woven fabric, and knitted fabric are added to the prepared aqueous solution of the fiber-degrading enzyme. By performing the operation of immersing, at the same time as the averaging treatment of the "hair fibers" of the cellulose fibers, yarns, woven fabrics and knits, the cellulose fibers, yarns,
Water molecules and fiber-degrading enzymes penetrate into the inside of woven and knitted fabrics, and the decomposition action of the enzymes makes it possible to efficiently progress the processing of cellulose fibers, yarns, woven and knitted fabrics, and the decomposition and removal action of impurities. . Since no special processing machine is required for carrying out the invention, the cost for fiber production can be reduced.

[0019] In particular, since there is no need to treat the fabric in hot water as in the conventional case, there is no entanglement phenomenon of the fabric, and there are problems such as shrinkage or damage to the fiber and discoloration of the fabric. Is completely eliminated, and there is no fear of partially leaving unprocessed parts, increasing flexibility and providing uniform “fiber”, cellulose fibers, yarns, woven fabrics, and knitted fabrics. The sensation can be significantly enhanced.
