(Industrial Application Field) The present invention relates to a deodorizing polyacrylonitrile (herein referred to as PAN) fiber and a method for producing the same, and more specifically to a deodorizing polyacrylonitrile (PAN) fiber that has excellent deodorizing properties and can be colored or dyed in any color tone. Concerning PAN fiber and its manufacturing method. (Prior Art) Conventionally, PAN fibers have been widely used as various clothing products and other process materials. (Problems to be solved by the invention) When conventional PAN fibers are used in socks, gloves, and other clothing that easily attracts body odor, or in clothing or other materials used in places where bad odors are generated. When used as clothing, it is desired that these clothing have deodorizing properties. As a way to meet such demands, these
It has been considered to incorporate deodorizing agents such as activated carbon and ferrous sulfate into PAN fibers. However, since activated carbon is black, it turns PAN fibers black, and ferrous sulfate has the problem of easily turning brown due to oxygen in the air, so PAN fibers require various beautiful colors. It could not be used for fibers. Therefore, there is a deodorizing PAN fiber that can absorb and remove unpleasant odors from the surrounding atmosphere for a long time without coloring the PAN fiber, and can be easily colored or dyed to any color. It is requested. (Means for Solving the Problems) That is, the present invention provides a deodorizing agent comprising a deodorizing agent comprising a nonvolatile organic carboxylic acid and a zinc compound, or a deodorizing agent comprising a zinc compound and an aluminum compound. PAN fiber and its manufacturing method. Next, to explain the present invention in more detail, the main feature of the present invention is that by incorporating a specific deodorizing agent into the PAN fiber, the beautiful coloring property that the PAN fiber originally has is not impaired in any way. , the PAN fiber has a long-term deodorizing effect. The PAN fiber referred to in the present invention refers to PAN itself and a high acrylonitrile copolymer containing PAN as a main component, for example, containing 80% or more of acrylonitrile, and these PAN fibers are conventionally known and widely used. It is something that The deodorizing agent incorporated into PAN fibers as described above must be white or substantially colorless, rather than black like activated carbon, and must have no color change. It is preferable that the odor should not be something that reduces the odor, and should be something that can satisfactorily absorb unpleasant odors such as ammonia odor, amine odor, hydrogen sulfide odor, etc. that occur in general homes. Examples of the deodorizing agent having the above characteristics include a mixture of a nonvolatile organic carboxylic acid and a zinc compound, or a mixture of a zinc compound and an aluminum compound. Preferred non-volatile organic carboxylic acids are aliphatic polycarboxylic acids, aromatic polycarboxylic acids and polymeric carboxylic acids. Preferred examples of fatty acid polycarboxylic acids include:
For example, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, fumaric acid, maleic acid, methylmaleic acid, methylfumaric acid, itaconic acid, citraconic acid, mesaconic acid, acetylenic acid, malic acid, methylmalic acid. ,citric acid,
Di- or tricarboxylic acids such as isocitric acid and tartaric acid, or salts thereof, and particularly preferred in the present invention are citric acid, fumaric acid, or salts thereof. Preferred examples of aromatic polycarboxylic acids include:
For example, phthalic acid, terephthalic acid, isophthalic acid, trimellitic acid, 1,2,3-benzenetricarboxylic acid, 1,3,5-benzenetricarboxylic acid, pyromethic acid, benzenehexacarboxylic acid,
Aromatic carboxylic acids such as naphthalenedicarboxylic acid, naphthalenetricarboxylic acid, naphthalenetetracarboxylic acid, diphenyltetracarboxylic acid, diphenyl ethertetracarboxylic acid, azobenzenetetracarboxylic acid, etc., or their anhydrides, particularly in the present invention. A preferred aromatic polycarboxylic acid is benzenetricarboxylic acid, especially trimellitic acid. In addition, examples of polymer carboxylic acids include citric acid,
Polyesters with terminal carboxyl groups obtained by reacting polycarboxylic acids such as tartaric acid and phthalic acid with polyhydric alcohols such as ethylene glycol, 1,4-butanediol, and diethylene glycol in excess of acid; modified with various polycarboxylic acids. Acidic cellulose derivatives; homopolymers such as vinyl ether ester monomers of polyhydric carboxylic acids, or random copolymers, block copolymers, graft copolymers, etc. with other common monomers; Homopolymers of monomers or random copolymers, block copolymers, graft copolymers, etc. with other common monomers; homopolymers of α,β-unsaturated vinyl monomers such as maleic anhydride and itaconic acid, etc. Examples include random copolymers, block copolymers, graft copolymers, etc. with polymers or other common monomers. By adding a zinc compound to the above nonvolatile organic carboxylic acid, hydrogen sulfide odor, which is another source of bad odor, can be absorbed at the same time as well as amine odor and ammonia odor. Examples of such zinc compounds include inorganic zinc compounds such as zinc oxide, zinc sulfate, zinc chloride, zinc phosphate, zinc nitrate, zinc carbonate, zinc acetate, zinc oxalate, zinc citrate, zinc fumarate, and formic acid. Organic zinc salts such as zinc can be used, but particularly preferred are zinc white (zinc oxide) and zinc carbonate. Such a zinc compound is blended in a proportion of 1 to 1000 parts by weight, preferably 30 to 300 parts by weight, per 100 parts by weight of the organic carboxylic acid. Furthermore, preferred white or substantially colorless deodorizing agents for the purposes of the present invention include those in which an aluminum compound is blended with the above-mentioned zinc compound. Such a deodorizing agent can also absorb unpleasant odors such as amine odor, ammonia odor, and hydrogen sulfide odor, which are sources of various bad odors, without reducing the desirable physical properties and dyeability of PAN fibers. Preferred aluminum compounds include aluminum sulfate and potassium aluminum sulfate, and these aluminum compounds are used in an amount of 1 to 100 parts by weight of the zinc compound.
It is used in a proportion of 1000 parts by weight, preferably 30-300 parts by weight. White or substantially colorless deodorizers such as those mentioned above.
Any method may be used to incorporate the deodorizing agent into the PAN fibers, but a preferred method is to add the deodorizing agent to the spinning dope during wet spinning of the PAN fibers, and to incorporate the deodorizing agent at the same time as spinning. . Such a stock solution coloring method is well known as a technique for coloring PAN fibers with pigments, and this method can be used as is in the present invention. A particularly preferred method is to prepare a masterbatch with a high deodorizer concentration from the deodorizer and PAN, and then add this masterbatch to the spinning dope for PAN fibers. The method for producing a deodorizing agent masterbatch may be similar to the conventional method for producing a coloring agent masterbatch. For example, PAN is dissolved in an organic solvent such as dimethylformamide, and the deodorizing agent is dissolved in this at a high concentration. For example, 10 to 200 per 100 parts by weight of PAN
A method of obtaining a masterbatch by adding parts by weight and sufficiently dispersing it to evaporate the solvent or precipitating it with a poor solvent, an organic solvent such as dimethylformamide, PAN, the above-mentioned deodorizing agent, and a grinding aid. Preferably used is a method in which an inorganic salt as an agent is mixed and thoroughly ground, and then water is added to elute the solvent and inorganic salt to obtain a masterbatch. By using the deodorizing agent masterbatch prepared in this way, the deodorizing agent is dispersed in the PAN fiber spinning dope, and the spinning nozzle is not clogged. In addition, in the present invention, since the nonvolatile organic carboxylic acid, which is one component of the deodorizing agent, can be easily dissolved in the spinning stock solution of PAN fiber,
This organic carboxylic acid is added as it is to the spinning stock solution for PAN fiber, while only the inorganic zinc compound and/or aluminum compound is made into a master batch using the above method, and this is added to the spinning stock solution to finally form a non-volatile organic carboxylic acid. The same effect can be obtained by incorporating the carboxylic acid and the above-mentioned inorganic components into the PAN fiber. Further, since the deodorizing agent masterbatch formed as described above is a white or substantially colorless masterbatch, a pigment of any hue may be added thereto to form a colored deodorizing agent masterbatch. or,
The present invention can also be carried out by using the above-mentioned deodorizing agent in conjunction with the coloring of the stock solution using pigments of the prior art. If the amount of the deodorizing agent incorporated into the PAN fiber is too small, the imparting of deodorizing properties, which is the intended purpose of the present invention, will be insufficient, and if the amount of the deodorizing agent incorporated in the PAN fiber is too large, the physical properties of the PAN itself may be deteriorated. As such, the preferred inclusion ranges from about 0.5 to 10 parts by weight per 100 parts by weight of PAN fiber. (Function/Effect) The deodorizing PAN fiber of the present invention as described above is capable of absorbing ambient foul odors such as amine odor, ammonia odor, hydrogen sulfide odor, etc. for a long period of time and deodorizing the ambient atmosphere. , the human body and the inside of the house can be maintained in a good atmosphere for a long period of time. In addition, the method of the present invention can be carried out by incorporating the above-mentioned preferred deodorizing agent into the spinning dope during the conventional coloring of the dope with pigments, so it does not require special industrial costs. Deodorizing property with the above effects in a very economical manner.
We can provide PAN fiber. Furthermore, since the deodorizing PAN fiber of the present invention is a white or substantially colorless deodorizing agent, the PAN fiber does not become colored. It can also be beautifully colored in any hue. (Example) Next, the present invention will be described in more detail with reference to Examples. In the text, parts or percentages are based on weight unless otherwise specified. Example 1 50 parts of zinc oxide, 10 parts of red pigment, 40 parts of PAN (degree of polymerization 1200) powder, 100 parts of common salt, and 75 parts of dimethylformamide were placed in a kneader with a pressure lid and a jacket for heating and cooling, and heated. Knead while stirring. When the contents become viscous and fluid, cooling begins and kneading is performed for 1 hour. Next, 25 parts of water is added to precipitate the minced meat, and the mixture is crushed in a kneader under pressure.
This is taken out and washed with water for about 5 hours until the salt and methylformamide are completely removed. The mixture was then dried in a hot air dryer at 70°C for 12 hours to obtain a master batch of deodorizer. 12.5 parts of this product was dissolved in 87.5 parts of dimethylformamide. The above solution and trimellitic acid were mixed at a concentration of 17%.
In dimethylformamide solution of PAN,
Zinc oxide and trimellitic acid were added at a ratio of 3 parts by weight and 1 part by weight per 100 parts by weight of PAN, and after thorough stirring, the mixture was left overnight to defoam. This colored spinning stock solution was heated to 0.08 mmφ and 100 mm at room temperature.
The present invention was colored red by spinning in n-butanol through a Hall spinning nozzle.
PAN fiber was obtained.
