Abstract: Изобретение относится к кожевенно-меховой промышленности и может быть использовано для обработки шкур. Способ обработки кожевой ткани шкуры предусматривает предварительную подготовку шкуры путем дубления водными растворами солей хрома трехвалентного при суточном вымачивании с последующей стиркой, вымачиванием в чистой холодной воде, высушиванием в центрифуге на 1000 оборотах и сушкой естественным способом. Далее шкуру натягивают на алюминиевую раму и поэтапно обрабатывают кожевую ткань шкуры наждачной бумагой на 1000 зерен, 2000 зерен, 3000 зерен, выдувая пыль компрессором. После этого шкуру натягивают на алюминиевую раму и выполняют покраску кожевой ткани путем нанесения рисунков ультрафиолетовой (УФ) струйной печатью с использованием УФ-отверждаемых чернил с последующим разминанием снятой шкуры с рамы. Далее шкуру устанавливают на деревянный щит и на кожевую ткань шкуры наносят шпателем тонкий слой полимера «клей-герметик Момент» и выполняют сушку естественным способом в течение суток, после чего обрабатывают поверхность УФ-лампой в течение 3-5 минут. Шкуру снимают со щита и вымачивают в течение 40 минут в теплой воде 50-60°С с добавлением соли поваренной. Затем шкуру высушивают в центрифуге на 1000 оборотах и снова натягивают на деревянный щит для естественной сушки. После этого шкуру снимают и разминают вручную и дальнейшую обработку кожевой ткани шкуры выполняют средством KENDA FARBEN для глянцевого или матового эффекта с последующей сушкой и обработкой поверхности шкуры вибрационной машинкой с войлочным диском. Предлагаемый способ обработки кожевой ткани шкуры обеспечивает повышение устойчивости к механическим повреждениям и к выцветанию кожевой ткани шкуры. 1 пр.
