Definitions

  • the present invention relates to a fiber treating agent containing a chitosan zirconium salt and fibers whose quality is improved by ion-bonding chitosan.
  • An important quality characteristic of fiber is good texture, which is related to the heat retention of the fiber.
  • the insulation is improved by hollowing the fibers to improve heat insulation, or by kneading ceramics, and in the case of natural fibers, the method of attaching and processing the ceramics with resin is used to maintain heat insulation. Fibers are being made.
  • such a method has a problem in that it takes too much time from yarn production to processing into a fiber product, and it is not possible to quickly respond to market demands.
  • hollow fibers have the disadvantage that they are weakly bent, and if natural fibers are adhered with resin by attaching resin, the texture becomes hard even if it has heat retention, resulting in a design effect. There is a problem.
  • chitosan which is a deacetylated product of chitin, and it is expected to improve antimicrobial properties and texture by including it in fibers.
  • the following two technologies are known for fixing chitosan to fibers.
  • One method is to knead the chitosan into the fiber, which is intended to prevent chitosan from falling off.
  • this method cannot be technically applied to natural fibers such as cotton, and is intended for specific fibers such as polyester and rayon.
  • chitosan is kneaded inside the fiber, so that chitosan is not much exposed on the surface of the fiber, so that the antibacterial effect is not so expected.
  • the other is a low-temperature heat treatment method, which is thought to be aimed at fixing the fibers to the fiber surface by simply heat-treating the fibers with chitosan, and is also applicable to natural fibers.
  • chitosan is simply settled at low temperature
  • an object of the present invention is to provide a fiber treating agent for binding chitosan to fibers for a long period of time, and to provide fibers whose antibacterial properties and heat retention properties are maintained over a long period of time by using the same. Things.
  • the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have completed the present invention.
  • the fiber treating agent of the present invention is characterized in that chitosan is ion-bonded (cross-linked) with a zirconium salt, and by using this, it is possible to ion-bond chitosan to fibers by treating the fibers. I have.
  • the fibers of the present invention have the property that they are not immediately absorbed when water comes in contact with a liquid, but are absorbed immediately and generate heat when they come in contact with water vapor. Therefore, when used as clothing, it is thought that liquid sweat absorbs only a small degree, while it has a high ability to absorb water vapor that evaporates from the surface of the skin, and the heat retention based on this enhances heat retention. That is, in the case of ordinary clothing, the liquid sweat wets the clothing, and when the liquid sweat evaporates, a large amount of heat is taken away. Is improved, and the effect is maintained for a long time. BEST MODE FOR CARRYING OUT THE INVENTION
  • the chitosan used in the present invention may be produced from chitin having a degree of acetylation of 1 to 100 as a raw material in a usual manner, and commercially available products can be used.
  • the zirconium salt that crosslinks chitosan can be employed without particular limitation as long as it is a water-soluble salt. Specific examples thereof include zirconium acetate, zirconium fluoride, and zirconium nitrate.
  • the fiber treating agent of the present invention is obtained by ion-bonding (cross-linking) chitosan with a zirconium salt, and is prepared by dissolving chitosan with an acid and then adding a water-soluble zirconium salt. .
  • chitosan When dissolving chitosan with an acid, for example, chitosan may be 2 to 10%, acid concentration may be 3 to 8%, and the remainder may be appropriately stirred with water.These concentrations may vary depending on the type of acid and the desired chitosan. It can be appropriately selected depending on the concentration.
  • the acid is not particularly limited, but generally an organic acid is preferred, for example, acetic acid, formic acid, citric acid or phosphorus acid. Goic acid and the like.
  • the zirconium salt is dissolved in hot water to make a 1 to 10% solution.
  • the above chitosan solution and zirconium aqueous solution are mixed at an arbitrary weight ratio of 1:99 to 99: 1, and the temperature is raised to 50 to 80 ° C and the reaction is performed for about 10 to 120 minutes. By doing so, a chitosan zirconium salt is obtained. At this time, chitosan is often in an oligosaccharide state.
  • the above-described chitosan zirconium salt is used as a fiber treatment agent.
  • the fibers referred to in the present invention include all kinds of filamentous fibers, raw fabrics, processed products using fibers, semi-finished products, and the like.
  • Any fiber material may be used, such as natural fibers (eg, cotton, wool, silk, hemp, etc.), synthetic fibers (eg, nylon, polyester, acrylic, rayon, etc.) or a blend of these.
  • the fibers are prepared by immersing chitosan in an aqueous solution of the chitosan zirconium salt under acidic conditions (usually at pH 3 to 5) at a temperature of about 20 to 60 ° C. by about 10 or more. Can be ionically bonded to The fibers after this treatment are dehydrated and dried as usual.
  • chitosan is used as a base material, and a zirconium salt is ion-bonded thereto.
  • Zirconium is an eight-coordinate ion with eight binding sites, so one to three of them are ionically bonded to chitosan and the remaining three are bonded to fiber.
  • An exothermic reaction occurs when the rest tries to combine with water molecules. Since this is a reversible reaction that occurs many times when chitosan tries to absorb water molecules, the zirconium ion does not change at all and exchanges water molecules as a catalyst, causing an exothermic reaction each time. happenss. This persists until the cationic groups of chitosan have completely absorbed the water molecule. Furthermore, when re-dried, the same phenomenon occurs again. The heat retention of the fiber is promoted by such a principle.
  • a chitosan solution containing 5% by weight of chitosan, 5% by weight of acetic acid, and 90% by weight of water was prepared.
  • zirconium acetate was dissolved in hot water to prepare a 5% by weight solution. 50 parts by weight of this chitosan solution and 50 parts by weight of a zirconium acetate solution were mixed and reacted at 60 ° C. for 60 minutes to obtain a chitosan oligosaccharide zirconium salt.
  • the chitosan oligosaccharide zirconium salt obtained in Example 1 was treated by adding 10% by weight to the wool thread.

  • Example 2 Using 20 g of the wool yarn and 20 g of untreated wool obtained in Example 2 as such, a woven fabric was produced under the same conditions as a test cloth. A drop of 1 m1 of water was dropped on each fabric in an atmosphere at a temperature of 18 ° C and a humidity of 40% RH (related humidity). At this time, the sedimentation velocity of each drop of water on the fabric was measured. The sedimentation speed here is the time until the water droplet is completely sucked into the fabric. Table 1 shows the measurement results.
  • a test cloth was prepared in which 20 g of wool treated with the present invention and 20 g of untreated wool were woven under the same conditions. Each cloth was sprayed with steam under the same conditions.
  • the steam conditions were as follows: using a domestic steam iron (made by National), 10 seconds after the start of the steam blast, it was confirmed that the steam blast was stable, and 30 seconds each from 15 cm above the test cloth.

  • the treated product of the present invention generates heat by absorbing water vapor. This is because wool that has been treated according to the present invention has a high ability to absorb water vapor. This indicates that heat is generated, that is, the heat retention is good.
  • the fibers to which chitosan is ion-bonded according to the present invention are those in which chitosan forms a coating on the surface of the fibers evenly and maintains heat retention and antibacterial properties over a long period of time. The antibacterial effect is exhibited even after repeating the above.
  • the fibers that have undergone this treatment, such as clothing, have heavy metal ⁇ contaminants that ooze out of the body together with perspiration, and the chitosan adsorbs them. Since heavy metals and contaminants are adsorbed and removed in this way, the skin is kept clean and effective for hygiene.
