Description
Известен способ растворени коллагена шкур животных, состо щий в том, что обводненный коллаген нодвергают сначала длительному золению, затем растворению при высоких температурах.A known method for dissolving animal collagen is that watered collagen is first exposed to long-term peeling, then dissolving at high temperatures.
Предлагаемый снособ улучшает качество раствора благодар тому, что коллаген подвергают сначала щелочно-солевой обработке, затем его нейтрализуют борной кислотой и выдерживают в кислой среде. При этом весь процесс растворени ведут на холоду.The proposed snoot improves the quality of the solution due to the fact that the collagen is first subjected to alkali-salt treatment, then it is neutralized with boric acid and kept in an acidic medium. In this case, the entire dissolution process is carried out in the cold.
Способ осушествл ют следующим образо.м.The method is carried out as follows.
Обводненный коллаген шкур обрабатывают 10%-ным раствором NaOH в присутствии солей например NaCl или Na2SO4 в течение 1 - 2 суток, при температуре не выше 20°С, при ж.к. 6-10 па сухой вес коллагена. Затем сливают отработанную жидкость и коллаген нейтрализуют растворами борной кислоты или кислых солей, промывают водой и выдерживают в кислой среде, имеющей рН не выше 2,5,Watered collagen skins are treated with a 10% NaOH solution in the presence of salts, such as NaCl or Na2SO4, for 1 to 2 days, at a temperature not higher than 20 ° C, while the case 6-10 pa dry weight of collagen. Then the waste liquid is drained and the collagen is neutralized with solutions of boric acid or acid salts, washed with water and kept in an acidic medium, having a pH not higher than 2.5,
при температуре от 3 до 20°С и ж.к. 40-100 в течение 24-48 час.at a temperature of from 3 to 20 ° C and zh.k. 40-100 within 24-48 hours.
Наилучшие результаты получают при применении органических кислот, в том числе уксусной кислоты и буферных растворов из органических кислот и солей.The best results are obtained when using organic acids, including acetic acid and buffer solutions from organic acids and salts.
Из полученных продуктов растворени коллагена можно получить волокна путем выделени их ацетоном или сол ми, например NaCl, NaoSO4, (NH4)2SO, и др.Fiber can be obtained from the obtained products of the dissolution of collagen by isolating them with acetone or salts, for example, NaCl, NaoSO4, (NH4) 2SO, and others.
Предмет изобретени Subject invention
Способ растворени коллагена шкур животных , отличающийс тем, что, с целью получени более качественного раствора, коллаген подвергают сначала щелочно-солевой обработке, затем его нейтрализуют борной кислотой или кислыми сол ми, промывают и выдерживают в кислой среде, при этом весь процесс растворени ведут на холоду.The method of dissolving animal collagen, characterized in that, in order to obtain a better solution, the collagen is first subjected to alkali salt treatment, then it is neutralized with boric acid or acid salts, washed and kept in an acidic medium, while the whole dissolution process is carried out to cold
