抗菌加工を施した物は、菌の繁殖を抑制するが悪臭その
ものを積極的に消臭する効果はない。Antibacterial-treated products suppress the growth of bacteria, but are not effective in actively eliminating bad odors.

A combination of an iron (If) compound and L-ascorbic acid (JP-A-59-132937) is known.

、充分な性能を具備した物がないのが現状である。However, these products have deodorizing properties, such as only one of the three major bad odors, nitrogen compound ammonia, sulfur compound mercaptan, and hydrogen sulfide, has a deodorizing effect. It is insufficient. In addition, since it is a granular activated carbon, liquid or powder deodorant, the carrier
It requires a protective material, has problems in handling and stable processability, and when used in shoe insoles, it is not durable against sweat, water, washing, friction, etc., and easily falls off. Due to this problem, there is currently no product with sufficient performance.

臭性能と耐久性を有する消臭用靴中敷が得られることを
見いだした。As a result of intensive research into the deodorizing mechanism of shoe insoles, the present inventors found that by using fibers containing a predetermined amount or more of transition metal ions bonded to carboxyl groups in the molecule, we achieved high deodorizing performance and durability. It has been found that a deodorizing shoe insole having the following properties can be obtained.

状態になっているものである。Regarding deodorizing fibers made of polymers having transition metals bonded to carboxyl groups in the molecules described in the present invention, details are given in Japanese Patent Application No. 62-47751. The fiber (1) is reacted with the transition metal compound (2), and most of the carboxyl groups in the fiber are in the state of carboxylic acid-transition metal salt.
（１）の分子中にカルボキシル基を有する高分子からな
る繊維の素材については、アクリル系繊維、メチルセル
ロース等があげられる。Examples of the fiber material (1) made of a polymer having carboxyl groups in its molecules include acrylic fibers and methyl cellulose.

充分な消臭性能を示さず、５．６ ｍｍｏｌ／ｇ繊維以
上ではこのアクリル系繊維は繊維紡糸性能、繊維強度等
の劣化により繊維としての形態をとることが難しい。In the case of acrylic fibers, the manufacturing method is to copolymerize a compound (3) having a carboxyl group during polymerization of acrylonitrile, or to copolymerize an acrylic fiber polymer copolymerized with a carboxyl group with other fibers. Methods such as composite spinning and oxidizing the acrylonitrile groups of acrylic fibers can be considered, but any method may be used. The carboxyl group-containing compound used in copolymerization may be either acrylic acid or methacrylic acid. The carboxyl group content is preferably 2.1 to 5.6 mmol/g fiber; less than 2.1 mmol/g fiber does not exhibit sufficient deodorizing performance, and 5.6 mmol/g fiber or more. However, it is difficult for this acrylic fiber to take the form of a fiber due to deterioration in fiber spinning performance, fiber strength, etc.

トリウム塩、アンモニウム塩等の塩の状態にして、遷移
金属化合物との反応を容易にすることが好ましい。This fiber is reacted with the transition metal compound (2), but at this time, the carboxyl groups are first neutralized using an alkali, such as sodium hydroxide or ammonia, and converted into salts such as sodium salts and ammonium salts. It is preferable to facilitate the reaction with the transition metal compound.
（２）の遷移金属としては、銅、銀、亜鉛、ニンケル、
コバルト等があげられ、好ましくは銅である。その遷移
金属の化合物についても、硫酸塩、酢酸塩、塩化物、水
酸化物等いずれでもよい。これらの遷移金属化合物の水
溶液中にこの繊維を浸せき処理して反応させた後、水洗
、脱水、乾燥することによって消臭繊維が得られる。The transition metals in (2) include copper, silver, zinc, nickel,
Examples include cobalt, and copper is preferred. The transition metal compound may be any of sulfates, acetates, chlorides, hydroxides, etc. Deodorizing fibers are obtained by immersing the fibers in an aqueous solution of these transition metal compounds to cause a reaction, followed by washing, dehydration, and drying.
靴中敷の形状および消臭繊維のいれ方についてはいろい

形状でも用いられる。又、活性炭等の吸着剤と併用する
と効果的である。There are many ways to think about the shape of the insole and how to insert the deodorant fibers, such as putting the deodorant fibers in a part of the insole, putting the deodorant fibers in the entire shoe, exposing the deodorant fibers to the surface, or wrapping them inside. It doesn't matter which one. Furthermore, the deodorant fiber can be placed in any shape such as woven fabric, knitted fabric, non-woven fabric, etc. Moreover, it is effective when used in combination with an adsorbent such as activated carbon.

可能である。Furthermore, it is also possible to use other deodorizing materials together with the deodorant fibers.

The copolymerized polymer was dissolved in 75% nitric acid and then spun in a 25% nitric acid bath to obtain a fiber (1) having a fineness of 3 denier. This fiber (1) was immersed for 15 minutes in a 2% I-+7um aqueous solution of hydroxide at room temperature, and then thoroughly washed in an ethanol solution containing 20% water to remove the carbon atoms in the fiber (1). After the acid is neutralized and the fiber is in the form of an alkali metal salt, it is immersed in a 5% aqueous solution of copper sulfate at room temperature for 10 minutes, washed with water, and dried to produce a fiber that is a deodorizing polymer in the form of a copper salt. (A) was obtained.

Among iron(n) compounds and L-ascorbic acid compounds, deodorizing performance was observed only for ammonia. Furthermore, no deodorizing performance was observed for those treated with antibacterial treatment.

It was measured. Also, ethyl mercaptan 30p
Similar measurements were made for pm.
