THE METHOD OF OBTAINING ANTI-MICROBIAL TEXTILE MATERIAL by treating the fibers from 2-methyl-5-VI copolymer copolymer with aqueous jpacT compound mercury is also distinguished by the fact that, in order to improve the antimicrobial properties of the material and their resistance to wet treatment, it is subjected to processing a text material, a material, a text material, a text material, and a wet material, a text material, a text material, and a wet material, a text material, and a wet material, a text material, and a wet material, a text material, a text material, and a wet material, can be used to improve the antimicrobial properties of the material and their resistance to wet treatment. -capropactam with 2-mep1l-5 -vinnlpyridine or from the above-mentioned copolymer, alkylated with hporacetamide, and 2-hydroxyethyl alcohol, with a concentration in the solution of 0.52 wt. t eo

Description

This invention relates to the technology of producing textile materials from these tetonic woks () with antimicrobial properties, which can be used for the manufacture of antimicrobial drapery materials, carpets, ha-lator, hats, bone and other products intended for use in medicine. Among the known compounds that impart antimicrobial properties to fibers,. mercury compounds are highly effective. Known methods of imparting antimicrobial properties to mercury compounds in vials using reactions that lead to the formation of either covalent or ionic bonds between the | tutu atom and the fiber, which in the first case causes insufficiently high antimicrobial properties of the windows, and in the second, insufficient stability of the antimicrobial properties of the fiber to wet treatments to which the windows are subjected during the operation of their products l. Closest to the proposed method of obtaining an antimicrobial textile material by treating a starting textile material from a copolymer of celkiose with 2-methyl-5-vnnylnridine with a 2% aqueous solution of acetic acid and mercury for 2 hours. However, the material treated by this method is insufficient. , high antimicrobial properties and low resistance of acquired antimicrobial properties to wet areas 3 - c1Hr-to-j tjf Hg. -.- B-dHf LY.

Ng - & - 5ng cG working. Thus, the zone of stunted growth of Staphylococcus aureus on a tissue sample before washes is 5 mm, and 2 mm after 40 washes. The purpose of the invention is to increase the antimicrobial properties of the material and their resistance to MOKJHJM treatments. This goal is achieved by the fact that according to the method of obtaining antimicrobial textile material wa Copolymer 2-1ethyl-5-4inylpyridine with an aqueous solution of mercury compounds, the B-Coxpolymer E-caprolactam textile material with 2-methyl-5vinylnnridine or from the mentioned copolymer, an allylated compound of an alkylated pattern, an allylated carbon pattern, or an alkylated compound of an alkylated compound, is used for processing. 2-hydroxyethyl mercurcyl chloride is used as a mercury compound with its concentration in the solution of 0.5-2 wt.%. The high antimicrobial activity of the material obtained, combined with the antimicrobial effect of repeated washings, is due to the fact that the mercury compound is bound to the fiber surface by a complex chemical bond combining the advantages of both covalent and ionic chemical bonds. Such a bond provides both a sufficiently strong chemical bond of the antimicrobial substance with the fiber (G1, as well as its optimal mobility necessary for the realization of the antimicrobial effect. ° Conventionally, the reaction can be expressed by the following schemes: iliz-OH g Nd -: - YYG-NGON | with 1 gui-B — fiber-forming. sropolymer. If a fiber is used from copolymer 6-capropactam with 2-methyl-5-vinyl pirschine, the reaction proceeds only according to scheme (I) | and when using fiber from the same copolymer t, alkylated chloroacetamide, -as according to the scheme (1), and according to the schemes (P), as a result of which the antimicrobial properties of the fiber are further enhanced. A method for obtaining o-caprolactam from 2-methyl-5-vinsch1 pyridine and fiber from this copolymer described in sources (33 and 41; fiber is used as the starting textile material; fabrics, three cats, etc. 1. The fiber obtained by PRI m e. p from a copolymer of caprolactam C. 2-methyl-5-vinylpyridine, containing 4 wt.% 2-methyl-5-vinylpyridine, is kept for 1 h. in a 2% aqueous solution of 2-hydroxyethyl mercurkchloride at 20 ° C. Then the fiber is prom Clean with water, air dry, and determine its mercury content and antimicrobial activity before and after repeated washes. PRI mme R 2. Volsnos from a block copolymer of caprolactam with 2-methyl-5-vinylpyridine, containing 4% by weight of 2-methyl-5-dinyl-pyridine, is alkylated with 10% solution of chloroacetamide at 80 ° C in for 4O-50 min. Knitwear is made from the obtained fibers. Samples of knitwear with an area of 2 cm are treated with 1 at 2 ° C in a 2% aqueous solution of 2-oxyethyl mercourt. Then the samples pr (x {ryut, dried in air and tested for mercury content and antimicrobial activity before and after repeated washings. Example 3. From the fiber obtained in example 2, make a fabric containing 50% fiber from block copolymer-caprolactam with 2- methyl 5-vinylpyridine, alkylated with chloroacetamide, and 5O% cotton. Fabric treated 1 8 8 water dissolved 2-hydroxyethylmerichloride analogously to example 2. Test the properties of the fiber according to examples 1-3 are as follows. The amount of mercury bound to the fiber is determined by burning of the fiber sample with the subsequent complexonometric titration of mercury ions. Determination of the antimicrobial activity of the fibers was carried out according to a known method by the method of agar-agar plates on patbgenic golden staphylococcus and pathogenic E. coli. -61 in a solution of the mighty agent Lotos with a concentration of 2 g / l at 4 ° -5 ° C for 5 minutes Properties of samples obtained according to Examples 1-3 are given in Table. 1. As can be seen from the table, the obtained fibers have a sufficiently high antimicrobial activity, which is maintained during repeated wet treatments. In tab. Figure 2 shows the effect of the concentration of 2-hydroxyethyl mercuric chloride in an aqueous solution on the antimicrobial properties of the fiber, characterized by a growth inhibition test zone of 1 microorganisms, with a fiber treating time in the indicated solution of 1 hour. 3: data on the antimicrobial properties of the fiber obtained at different processing times of the initial fiber from a block copolymer of caprolactam with 2-methyl-5-vinylyridine in 2% aqueous solution of 2-hydroxyethyl mercurchloride. In tab. 4 shows data on anti-. microbial properties of the fiber obtained by the i-th processing of the original fiber from the block copolymer of E-caprolactam alkylated with chloroacetamide in 1% solution: D 2-hydroxyethyl mercurchloride depending on the processing time. As can be seen from the data table. 1-4, the invention makes it possible to obtain textile, material with enhanced antimicrobial properties and resistance of these properties to wet treatments.
