Description
Предлагаемое изобретение касаетс способа закреплени основных красителей на растительных волокнах с помощью продуктов конденсации фенола с фурфуролом. В литературе известен способ закреплени основных красителей на растительных волокнах с помощью продуктов конденсации фенолов с альдегидами (см., например, герм, пат, № 562509).The present invention relates to a method for fixing basic dyes on plant fibers using phenol-furfural condensation products. In the literature, there is a known method of fixing basic dyes on plant fibers using condensation products of phenols with aldehydes (see, for example, germs, US Pat. No. 562509).
Автором насто щего изобретени установлено, что продукты конденсации фурфурола с фенолом вл ютс при растворении их в щелочах или органических растворител х хорошими закрепител ми дл основных красителей на растительных волокнах. Способ применени выщеуказанных закрепителей аналогичен обычно примен емым закрепител м И.Т. или катанолю. Ткань, плюсованйа основным красителем, сущитс и проводитс на ходовом аппарате через щелочный раствор закрепител в зависимости от интенсивности крашени при температуре, равной 60°. Дл предупреждени выпадени закрепител от действи уксусной кислоты, остающейс в товаре, к раствору закрепи-, тел прибавл ют соду в количестве 3-5 г на 1 литр.The author of the present invention has found that the condensation products of furfural with phenol, when dissolved in alkalis or organic solvents, are good fixatives for basic dyes on vegetable fibers. The method of application of the above fixers is similar to the commonly used fixers I.T. or katanoly. The fabric, plus the main dye, was dried and carried out on the undercarriage through an alkaline fixative solution, depending on the intensity of dyeing at a temperature of 60 °. In order to prevent the fixative from falling out of the action of acetic acid remaining in the product, soda in an amount of 3-5 g per 1 liter is added to the fixative solution.
После плюсовани -воздущный зрельник с лежкой (1 минута) и промывка на теплой воде.After padding, an aird brew with a mattress (1 minute) and rinsing with warm water.
Получаемые окраски по прочности к мылу не хуже, чем окраски, получаемые с катанолем, несколько уступа последним по устойчивости к действию света.The resulting stains for strength to soap are not worse than the stains obtained with catanol, a few steps to the last for resistance to the action of light.
По оттенку и ркости окраски, получаемые с закрепителем из фенола и фурфурола с сафранином, родамином В, родамином б GDN, значительно превосход т окраски, соответственно получающиес с закрепителем ИТ.In terms of hue and brightness, the colors obtained with phenol and furfural fixative with safranin, rhodamine B, rhodamine GDN significantly exceed the colors, respectively, obtained with IT fixer.
Пример. Смесь, состо щую из 100 г фенола, 70 г бО/о-го фурфурола и 30 г едкого натра 38° Вё, нагревают на вод ной бане при температуре 90° в течение 8 часов в глин ной или медной посуде. Полученный продукт конденсации смещивают со щелочью в отношении 5:4, раствор ют при легком подогревании в воде и примен ют, как выше описано.Example. A mixture consisting of 100 g of phenol, 70 g of bo / o-furfural and 30 g of caustic soda 38 ° We, is heated in a water bath at a temperature of 90 ° for 8 hours in earthenware or copper ware. The resulting condensation product is shifted with an alkali in the ratio of 5: 4, dissolved in light water and applied as described above.
