manufacture example 1
[0024] Hereinafter, the present invention will be described in more detail using production examples and examples, but the present invention is not limited to these examples. Production Example 1 [Manufacture of citric acid L-lysine cellulose partial ester salt]
[0025] 2.33 g (10 mmol) of L-lysine methyl ester dihydrochloride was dissolved in 15 mL of methanol, and 5 mL of a 2N aqueous sodium hydroxide solution was added thereto to obtain a treatment solution. 5.0 g of cotton non-woven fabric (C × 32 produced by Hanilon Co., Ltd.) was immersed in this treatment agent solution for about 30 seconds, and after being air-dried for 1 hour, it was heat-treated at 140° C. for 20 minutes. It was repeatedly washed with water, washed with 5% by weight aqueous sodium bicarbonate solution and water three times, and washed with 10% by weight aqueous citric acid solution and washed three times with water. Then, it was dehydrated, air-dried, and used as a sample. A part of this sample wa...
manufacture example 2
[0026]From this result, the bound amount of L-lysine corresponding to 1 g of the sample was calculated to be 0.105 mmol (esterification substitution degree 0.017). In addition, the citric acid in this detection liquid was quantified by high-performance liquid chromatography (HPLC), and the binding amount of citric acid corresponding to 1 g of samples was calculated as 0.190 mmol from the result. Production Example 2 [Manufacture of citric acid L-arginine cellulose partial ester salt]
[0027] The same experiment as in Production Example 1 was performed except that 2.61 g (10 mmol) of L-arginine methyl ester dihydrochloride was used instead of L-lysine methyl ester dihydrochloride in Production Example 1. The amount of bound L-arginine corresponding to 1 g of the sample was calculated to be 0.109 mmol (degree of esterification substitution: 0.018) by the same method as in Production Example 1. Also, the binding amount for the citric acid experiment was 0.162 mmol.
Embodiment 1
[0028] Example 1: Manufacture of socks
[0029] 5.83 g (25 mmol) of L-lysine methyl ester dihydrochloride was dissolved in 20 mL of methanol, and 12.5 mL of a 2N aqueous sodium hydroxide solution was added thereto to obtain a treatment solution. Soak pure cotton socks (about 25g) in the treatment solution for about 20 seconds, air-dry them for 2 hours, and heat them at 140°C for 20 minutes. It is washed repeatedly with water first, then washed with 5% by weight of sodium bicarbonate aqueous solution and washed 3 times with water, washed with 10% by weight of citric acid aqueous solution and rinsed with water for 3 times, and then washed with household neutral detergent and washed with water. , dehydrated, and air-dried to obtain socks of the present invention.
