Problems solved by technology

[0007] However, it is considered that the common problem of these methods disclosed is that since any of these are substances containing antibacterial agents or metals in a part of the product, and the form containing these antibacterial ingredients is mixed, attached or ionically bound, and therefore may be the cause of an allergic reaction due to dissolution into body fluids secreted, exuded, or excreted from the organism, or detached by friction with the skin, mucous membranes, or wounds

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.

Abstract

According to the present invention, a cellulose fiber or a fiber product made of said cellulose fiber is contacted with a basic amino acid ester and thereafter heat treated, thereby there may be provided an antibacterial product which does not lose its antibacterial property even by being washed several times. The fiber product is excellent in antibacterial property, deodorant property and safety and suitable for use as an antibacterial product such as socks, towel or the like which especially an odor becomes a problem due to the propagation of bacteria during using or storing it, and further it is suitable for use as a medical or sanitary article.

Description

technical field [0001] The present invention relates to fiber products with excellent antibacterial properties, deodorant properties, washability and safety. More specifically, the present invention relates to a fiber product comprising a partial basic amino acid cellulose ester and / or a salt thereof, or a fiber product comprising a cellulose fiber obtained by contacting a cellulose fiber with a basic amino acid ester and then heat-treating it. [0002] Also, the present invention relates to the use of fiber products excellent in antibacterial properties and safety as medical or hygienic products. Background technique [0003] Since the growth of bacteria during use or storage of textile products often leads to undesirable results such as bad odor, antibacterial treatment has been applied to cloth products such as socks and towels where bad smell is particularly a problem in the past. In recent years, under the background that infections of neopenicillin I-resistant Staphyl...
