Description

По существующим способам различные кожи ДоТ  увлажнени  окунают , обрызгивают или помещают во влажные опилки. Все эти способы требуют последующей длительной пролежки увлажненных кож в укрытом виде или в специальных камерах дл  равномерного распределени  влаги по всей площади и толщине кожи, вследствие Вгсьма медленной диффузии воды с поверхности в дерму кожи под действием градиента влажности.According to the existing methods, various skin DoT moisturizings are dipped, sprayed or placed in wet sawdust. All of these methods require the subsequent prolonged passage of moist skin in covered form or in special chambers to evenly distribute moisture over the entire area and thickness of the skin, due to the slow diffusion of water from the surface into the dermis of the skin under the influence of a moisture gradient.

Внедр емый в последнее врем  способ увлажненн  кож в атмосф:;ре насыщенного влагой воздуха (в паровоздушной среде), хот  и позвол ющий устранить стадию пролежки, св зан со значительным расходом тепла , длительностью процесса (не менее 3-4 час.) и т желыми услови ми работы.The recently introduced method of moisturizing the skin into the atmosphere:; re-saturated air (in the vapor-air medium), although allowing the elimination of the decay phase, is associated with significant heat consumption, process duration (at least 3-4 hours) and t conditions of work.

Предлагаетс  способ увлажнени  кож, мехов и деталей из них, основанный на нринципе термодиффузии влаги, котора  может происходить при наличии разницы в температуре отдельных слоев кожи. Скорость термодиффузии влаги пропорциональна разности этих температур и при соответствующих услови х может быть значительно больше скорости диффузии под действием градиента влажности.A method is proposed for moistening leathers, furs and parts made of them, based on the principle of thermal diffusion of moisture, which can occur if there is a difference in temperature between individual layers of the skin. The rate of thermal diffusion of moisture is proportional to the difference between these temperatures and, under appropriate conditions, it can be much higher than the diffusion rate under the action of a gradient of humidity.

По предлагаемому способу процесс увлажнени  заключаетс  в следующем .According to the proposed method, the process of moistening is as follows.

После сушки кожи смачивают теплой водой (желательно с добавлением смачивающих веществ) по бахтарме или с обеих сторон (в зависимости от толщины кожи) обрызгиванием в проходном шприц-агрегате или в стационарной 1пприц-камере, после чего их сразу же подвергают быстрому (примерно 30-60 сек.) нагреву с увлажненной стороны, соприкосновением с гор чей (180-130) поверхностью, например, на гидропрессе , проходной мерейной машине или на каландре с гор чим гладким валом.After drying, the skin is moistened with warm water (preferably with the addition of wetting agents) bahtarma or on both sides (depending on the skin thickness) by spraying in a passing syringe assembly or in a stationary 1 syringe chamber, after which they are immediately subjected to rapid (approximately 30 60 sec.) Heating from the wetted side, contact with a hot (180–130) surface, for example, on a hydraulic press, through a slurry machine or on a calender with a hot smooth shaft.

Большой перепад температур но сло м кожи вызывает быстрое передвижение воды от гор чей поверхно.-:ти к холодной через всю толщу кожи, что приводит к. быстрому и равномерному увлажнению ее. К томуA large temperature drop over the skin’s layers causes the rapid movement of water from the hot surface. To that
