Description
Известен способ вакуумного крашени трикотажных изделий, текстильных волокон и т. п., с применением предварительного вакуумировани изделий и последующей пропиткой их красильным раствором. Однако при этом способе сорбци красителей протекает недостаточно быстро.There is a known method of vacuum dyeing knitwear, textile fibers, etc., using pre-vacuuming products and then impregnating them with a dye bath. However, with this method, the sorption of dyes is not fast enough.
По описываемому способу вакуумного крашени дл ускорени процесса и повышени качества изделий красильный раствор после пропитки изделий нагревают до температуры, превышающей 100°, и процесс крашени ведут при избыточном давлении.According to the described vacuum dyeing method, to speed up the process and improve the quality of the products, the dye solution after impregnation of the products is heated to a temperature in excess of 100 °, and the dyeing process is carried out at an overpressure.
Применение описываемого способа осуществл ют следующим образом.The application of the described method is carried out as follows.
Вакуум-аппарат загружают трикотажными издели ми, текстильными волокнами и т. п., затем его герметически закрывают и производ т вакуумирование изделий в течение 3-10 мин до остаточного давлени 0,1-0,3 мм рт. ст. После этого вакуум-аппарат соедин ют со сборником, где произведена предварительна подготовка и подогрев красильного раствора до 40-100. После перекачки красильного раствора в ванну крашени подключают паропровод и поднимают температуру выше 100°, например до 101-108°. При этой температуре процесс крашени проходит ускоренно, в пределах 15 мин. После окончани крашени раствор спускают, издели промывают и выгружают. Во врем процесса вакуумируютс лишь издели , а вакуумироваиие раствора не требуетс .The vacuum apparatus is loaded with knitwear, textile fibers, etc., then it is hermetically sealed and the products are evacuated for 3-10 minutes to a residual pressure of 0.1-0.3 mm Hg. Art. After that, the vacuum apparatus is connected to the collection, where the preliminary preparation and heating of the dye solution is made to 40-100. After pumping the dye solution into the dye bath, the steam line is connected and the temperature is raised above 100 °, for example, to 101-108 °. At this temperature, the dyeing process is accelerated, within 15 minutes. After finishing the dyeing, the solution is lowered, the products are washed and unloaded. During the process, only products are evacuated, and no vacuuming of the solution is required.
Предмет изобретени Subject invention
Способ вакуумного крашени трикотажных изделий, текстильных волокон и т. п., с применением предварительного вакуумировани изделий и .последующей пропиткой их красильным раствором, отличающийс тем, что, с целью ускорени процесса и повышени качества изделий, красильный раствор после пропитки изделий нагревают до температуры , превышающей 100°, и процесс крашени ведут при избыточном давлении.A method of vacuum dyeing knitwear, textile fibers, etc., using pre-evacuation of products and subsequent impregnation with their dyeing solution, characterized in that, in order to speed up the process and improve the quality of the products, the dyeing solution is heated to exceeding 100 °, and the process of dyeing is carried out at an overpressure.
