The transition metal compound may be applied on a layer containing a deodorant together with an antibacterial agent and a water absorbing agent, or may be previously contained in a fiber product containing polyamide fibers.
[0020]
When the transition metal compound is reacted with a polycarboxylic acid to convert a part or all of the carboxy groups of the polycarboxylic acid into salts, the deodorizing effect on sulfur-based malodorous substances, such as methyl mercaptan and hydrogen sulfide, is greatly improved.
[0021]
According to the present invention, by performing antibacterial deodorization, deodorization, and water absorption processing, deodorization efficiency is improved, and a decrease in water absorption by an antibacterial agent can be suppressed, and the amount of the deodorant applied can be reduced. It is possible to provide a multifunctional product economically.
Furthermore, since water absorption is provided, there is no stickiness at the time of perspiration, and it is possible to spend comfortably.
[0022]
【Example】
Examples are described below to describe the present invention more specifically, but the present invention is not limited by these.
[0023]
Example 1
Nylon / polyurethane tricot knitted fabric is treated with an α, β-unsaturated dicarboxylic anhydride-based deodorant (Zeon Chemical Co., Ltd., Zeon Clean 1015A) so as to have a 6% owf and a water-soluble crosslinking agent (Zeon Chemical Co., Ltd.) , Zeon Clean 1015B) in a working fluid containing 0.6% owf, and heat-treated at 170 ° C. Then, a quaternary ammonium salt cationic antibacterial agent (Nikkanon RB, manufactured by Nikka Chemical Co., Ltd.) 0.5% owf, a polyalkylene oxide polyamide-based water-absorbing agent (manufactured by Takamatsu Yushi Co., Ltd., Ranogen TNT-2) and a copper compound (Zeon Kasei Co., Ltd., ZEON CLEAN 1015C) were added in an amount of 2%. It was immersed in a working fluid containing 0.5% owf and heat-treated at 170 ° C. to perform a two-step process to obtain an antibacterial deodorant, deodorant, and water-absorbing fabric. The cloth was washed 10 times using a neutral detergent Monogen Uni (manufactured by P & G) according to the JIS L-0217103 method, and the water absorption, deodorization rate, and antibacterial property before and after washing were evaluated. Table 1 shows the results.
[0024]
Example 2
An antibacterial deodorant, deodorant and water-absorbing fabric was obtained in the same manner as in Example 1 except that the content of the copper compound was changed from 2.5% owf to 1.5% owf. The water absorption, deodorization rate, and antibacterial property of the fabric after about 10 washes were evaluated. Table 1 shows the results.
[0025]
Comparative Example 1
An antibacterial deodorant, deodorant, and water-absorbing fabric was obtained in the same manner as in Example 1 except that no copper compound was used. The water absorption, deodorization rate, and antibacterial property of the fabric after about 10 washes were evaluated. Table 1 shows the results.
[0026]
Comparative Example 2
An antibacterial deodorant, deodorant and water-absorbing fabric was obtained in the same manner as in Example 1 except that no water absorbing agent was used. The water absorption, deodorization rate, and antibacterial property of the fabric after about 10 washes were evaluated. Table 1 shows the results.
[0027]
Comparative Example 3
Without any treatment, the nylon / polyurethane tricot knitted fabric was evaluated for water absorption after about 10 washes, the deodorizing rate of the knitted fabric, and the antibacterial property. Table 1 shows the results.
[0028]
The deodorization rate, antibacterial property and water absorption were evaluated as follows.
Deodorization rate: 1 g of a work cloth was placed in a 120 ml glass container, 607 ppm of ammonia and 120 ppm of methyl mercaptan were injected, and the remaining amount of ammonia and methyl mercaptan was measured by gas chromatography after 30 minutes.
[0029]
Antibacterial property: The processed cloth was placed on an agar medium inoculated with Staphylococcus aureus, and the bacteria were cultured at 37 ° C. for 24 hours. The antibacterial property was evaluated based on the presence or absence of growth of Staphylococcus aureus around the processed cloth.
：: No growth of bacteria was observed around the work cloth, and halos were generated.
Δ: No growth of bacteria was observed, but no halo was generated.
×: Growth of bacteria is observed.
[0030]
[Table 1]
【The invention's effect】
The fiber product of the present invention is a fiber product containing a polyamide-based fiber having improved detergency, antibacterial property and water absorbency, having improved washing durability. Further, according to the method of the present invention, deodorizing efficiency of the product is improved by performing antibacterial deodorization, deodorization, and waterproofing, and a decrease in water absorption due to the antibacterial agent can be suppressed. Therefore, the amount of the deodorant can be reduced, which is economically advantageous.
