Известен опоооб получени антими1Краблого волокна Путем модификации лоливинилcinnpTOiBoro волокна 1аль(дегвдами 5- ит1рофуранового )р да р-(5-,иитрофурил-2)-акролеин (НФА) и др.. По этому способу волокно обрабатываетс водньгм или в одно-спиртовым .растворам нитрофурилакролеина. Осиовиым недостаткам этого способа вл етс сравнительно небольшое содержание нитрофу)рила;к ролеина на волокне и, 1соатветст1венно, недостаточно высока 1антими1кроб«а активность получаемых 1воло«о«, особевно три иопользо (ваиии их iB смеси с другшМИ неантимикробны;ми волокна-мл (степень замещени таких ант (имикрО|бных волокон НФА составл ет 7-10 мол. %). Это св зано с малой растворимостью нитрофурила-кролеина в воде (максимальна растворимость 5 г НФА на 100 г воды).Known anti-antimicrobial fiber by modifying lolivinylcinnpTOiBoro 1al fiber (degvdami 5-it1ofuranovogo) row p- (5-, iitrofuryl-2) -acrolein (NPA) and others. In this method, the fiber is treated with water or in one alcohol. nitrofuryl acrolein. The axiomatic drawbacks of this method are relatively low levels of nitrofuranyl, to rolin on the fiber and, consistently, not high enough for anti-bacteria and the activity of the obtained o, especially three ipolz (their iB mixtures are different from other antimicrobials; the degree of substitution of such ant (imfra | biofibers of NFA is 7-10 mol.%). This is due to the low solubility of nitrofuryl-krolein in water (the maximum solubility of 5 g of NFA per 100 g of water).
Дл 1по1вышени ра1ст1воримости иитрофурилакролеина и, тем самым, дл увеличени содержани его на волокне до 15-;20% предлагаетс IB 1а1цеталирующий раствор вводить Я:иметил1азльфок1сид в количестве ,20-30%. По физкко-механическим показател м волак но трактвчеаки не отличаетс от волокна, об.работакноро водным или вадно-опиртавым pacTiBOpOM НФА (прочность его составл ет .201-25 гс/гекс).In order to increase the solubility of nitrofuryl acrolein and, thus, to increase its content on the fiber to 15–; 20%, IB: 1–1 acetalizing solution is added to I: imethyl acid in an amount of 20–30%. In terms of physical and mechanical parameters, wolf no tract does not differ from the fiber, but the working or aqueous or high-grade pacTiBOpOM NPA (its strength is .201-25 gf / hex).

полученный раствор томещают термообработаиное поливлпил апиртовое волокно и обрабатывают 1,5-2 час. После обработки волокно промывают водой и сущат.The resulting solution is heated by heat-treated polyvinyl alcohol and treated for 1.5-2 hours. After processing, the fiber is washed with water and it is present.
