Description
Известно, ЧТО при крашении шерсти на посто нной ванне в .кислой среде ванна -постепенно обогаш,аетс водорастворимыми родуктами кислотного гидролиза шерсти, т. е. продуктами КИСЛОТНОГО распада кератина . Эти продукты в известной мере защиш,ают шерсть от вредного действ:и Кислот и щелочей, а также способствуют получению равномерных окрасок кислотными красител ми .It is known that when dyeing wool on a constant bath in an acidic environment, the bath is gradually enriched with water-soluble products of acid hydrolysis of wool, i.e. products of ACID keratin decomposition. To a certain extent, these products protect the wool from harmful effects: both Acids and alkalis, and also help to obtain uniform dyes with acid dyes.
ВодораствОри1мые продукты распада кератина можно также получить путем обработки природных содержащих кератин материалов водой под давлением при температуре выше 140°. Однако указанные выше Продукты как кислотного, так и нейтрального гидpOv изa (распада) кератина не получили Т1ракт1ического применени дл отделки текстильных материалов животного или растительного происхождени .Waterborne keratin decomposition products can also be obtained by treating natural keratin-containing materials with water under pressure at a temperature above 140 °. However, the above products of both acidic and neutral hydropic acid (decomposition) of keratin did not receive a practical use for the finishing of textile materials of animal or vegetable origin.
Автором установлено, что если гидролиз природных кератиносодержапшх материалов водой под давлением при температуре выше 140° вести в присутствии формальдегида , то можно получить новыеThe author found that if the hydrolysis of natural keratin-containing materials with water under pressure at a temperature above 140 ° is carried out in the presence of formaldehyde, then new ones can be obtained
растворимые в воде продукты распада кератина, содержащие св занный формальдегид и в отличие от выщеописанных продуктов кислотного нейтрального гидролиза пригодные дл отдеоТки волокнистых материалов.water-soluble keratin degradation products containing bound formaldehyde and, unlike the acid neutral hydrolysis products described above, suitable for fissioning fibrous materials.
Предложенный способ даст возможность регулировать степень расщеплени белка кератина.The proposed method will make it possible to regulate the degree of keratin protein degradation.
По другому варианту природные кератиносодерл ащие материалы обрабатывают водой под давлением при температуре выше 140° и от полученных таким образом водорастворимых продуктов распада кератина, содержащих св занный формальдегид, отщепл ют последний путем обработки минеральной кислотой при нагревании, после чего нейтрализуют. И в этом случае получают ранее неизвестные водорастворимые продукты распада кератина , не Содержащие формальдегида и также пригодные дл отделки волокнистых материалов.Alternatively, natural keratin-containing materials are treated with water under pressure at a temperature above 140 ° and the water-soluble keratin decomposition products containing bound formaldehyde are obtained in this way, the latter is cleaved by treatment with mineral acid under heating, and then neutralized. And in this case, previously unknown water-soluble keratin decomposition products are obtained that do not contain formaldehyde and are also suitable for finishing fibrous materials.
Пример 1. 50 г человеческого волоса нагревают с 400 г 30%-ного раствора формальдегида в течениеExample 1. 50 g of human hair is heated with 400 g of a 30% formaldehyde solution for
3 час. в закрытом сосуде при 145- 150°. После этого ползченный раствор охлаждают, фильтруют и упаривают до «оноистенции сиропа. Получают частей продукта, содержаще-щ ., бЛ -частей формальдегида .3 hours in a closed vessel at 145-150 °. After that, the creeped solution is cooled, filtered and evaporated to “onto the persistence of the syrup. Receive parts of the product containing-sh., BL-parts of formaldehyde.
Пример 2. 50 г ротовой стружки обрабатывают 500 г 30%-кого раствора формальдегида, как в примере 1. К отфильтрова«ному раствору продуктов реакции добавл ют 10 г концентрированной серной кислоты и нагревают на вод ной бане до удалени св занного и свободного формальдегида, после чего фильтруют, нейтрализуют « упаривают . Выход - 140 частей сухих растворимых в воде продуктов распада кератипа.Example 2. 50 g of oral chips are treated with 500 g of a 30% formaldehyde solution, as in Example 1. 10 g of concentrated sulfuric acid is added to a filtered solution of the reaction products and heated on a water bath until the bound and free formaldehyde is removed, then filtered, neutralized “evaporated. Output - 140 parts of dry water-soluble keratype degradation products.
