Embodiment 1
[0042] 4.66g (20mmol) of L-lysine methyl ester dihydrochloride, 2.22g (6.2mmol) of disodium phosphate 12 hydrate and 0.2g of polyethylene oxide lauryl ether ("newcol 1100", Japan Emulsifier Co., Ltd. nonionic surfactant) was dissolved in 10.0 ml of water to prepare a treatment agent solution. Cotton cloth (200 mm x 200 mm, 7.5 g) was dipped in 25% sodium hydroxide aqueous solution at room temperature for 1 hour beforehand, washed with water, and dried. After making the treated cotton cloth absorb the total amount of the treatment agent liquid evenly, it was air-dried at room temperature for 3 hours. It was heated at 140°C for 20 minutes in a batch-type hot air oven (Tavaies back (stock), Inert oven "IPHH-2000"), washed with water, and then washed with 5% soda water and washed with water three times. , 3 times of 10% citric acid aqueous solution washing and water washing, finally washing with household detergent, washing with water, and air drying. The produced L-lysine cellu...
Embodiment 2
[0044] 5.22 g (20 mmol) of L-arginine methyl ester dihydrochloride, 2.22 g (6.2 mmol) of disodium phosphate 12 hydrate and 0.2 g of polyethylene oxide lauryl ether ("new col1100", A nonionic surfactant manufactured by Nippon Emulsifier Co., Ltd.) was dissolved in 10.0 ml of water to prepare a treatment agent solution. Cotton cloth (200 mm x 200 mm, 7.5 g) was previously immersed in 25% sodium hydroxide aqueous solution at room temperature for 1 hour, washed with water, and dried. After the treated cotton cloth absorbs the total amount of the aforementioned treatment agent liquid evenly, it is air-dried at room temperature for 3 hours. It was carried out at 140°C for 20 minutes in a batch-type hot air oven (Tavaies back (stock), Inert oven "IPHH-2000"), washed with water, and then washed with 5% soda water and washed with water repeatedly three times, 3 washes with 10% aqueous citric acid and water, and finally, rinse with household detergent, wash with water, and air dry.

Embodiment 3
[0046] 4.84g (20mmol) of L-histidine methyl ester dihydrochloride, 2.22g (6.2mmol) of disodium phosphate 12 hydrate and 0.2g of polyethylene oxide lauryl ether ("newcol1100", Japan A non-ionic surfactant manufactured by Emulsifier Co., Ltd.) was dissolved in 10.0 ml of water to prepare a treatment agent solution. Cotton cloth (200 mm x 200 mm, 7.5 g) was dipped in 25% sodium hydroxide aqueous solution for 1 hour at room temperature, washed with water, and dried. After making the treated cotton cloth absorb the total amount of the treatment agent liquid evenly, it was air-dried at room temperature for 3 hours. It was carried out at 140° C. for 20 minutes in a batch-type hot air furnace (Tavaies back (stock), Inert oven "IPHH-2000"), after heat treatment, washed with water, and then repeatedly washed with 5% soda water and washed with water three times, 3 washes with 10% aqueous citric acid and water, and finally, rinse with household detergent, wash with water, and air dry.
