Изобретение относитс к кожевенно обувной промьшшенности и может быть использовано дл вьфаботки кожи дл низа обуви.The invention relates to leather and footwear industry and can be used to work the leather for the bottom of the shoe.
Цель изобретени - улучшение качества голь , а также условий труда.The purpose of the invention is to improve the quality of the mole, as well as working conditions.
Отличительной особенностью изобретени вл етс тот факт., что полиакриламид проникает в структуру коллогена , увеличива его объем, при . этом происходит набухание и частичное растворение белкового вещества, креп щего волос к коже. Кррме того, полиакриламид поглощает вредные продукты распада белков, вьщбл ющиес при золении.A distinctive feature of the invention is the fact that polyacrylamide penetrates into the structure of the collogen, increasing its volume, at. this results in swelling and partial dissolution of the protein substance that binds the hair to the skin. In addition, polyacrylamide absorbs the harmful degradation products of proteins that occur during salting.
Пример. Мокросоленое сырье отмачивалось в течение 1 сут при 16 С. Затем оно подвергалось обработке водным раствором полиакриламида в количестве 3-4% от парного веса сьфь при 22 С. рН раствора 11-12. Полное ослабление св зи волоса с дермой наблюдалось через 3-4 сут. После чего производили сгонку волоса и обеззоливание сульфатом аммони в количестве 2,5% от массы голь .Example. Wet raw materials were soaked for 1 day at 16 C. Then it was treated with an aqueous solution of polyacrylamide in an amount of 3-4% of paired weight at 22 C. The pH of the solution is 11-12. A complete weakening of the bond between the hair and the dermis was observed after 3-4 days. After that, the hair was pulled and the ammonium sulfate was desoldered in the amount of 2.5% by weight mole.
Указанным образом бьши обработаны образцы по примерам 1-6.In this way, the samples of examples 1-6 were processed.
Результаты приведены в таблице.The results are shown in the table.
