dc.description.abstract This study investigates the possibility to obtain high quality in the foam dyeing of wool at a temperature below 80oC by establishing a mathematical model of the process. In the experiments scoured wool was used. The dyestuff that was tested was Acid Red 17, C.I. 16180. The mathematical model of the process allowed us to emphasize the big importance that the temperature of the foamed solution has upon the dye uptake. It has been concluded that best results are obtained at a temperature of 80,7oC, upper values determining modest characteristics of the foams. It was found that the role of the foaming agent concentration is of lesser importance. en_US
dc.description.abstract În lucrare s-a analizat posibilitatea obţinerii vopsirii corespunzătoare din punct de vedere calitativ prin procedeul de vopsire a lânii la temperatură scăzută din spumă prin stabilirea unui model matematic al procesului. Experimentele s-au efectuat asupra lânii degresate, folosind colorantul Acid Red17, C.I.16180. Modelul matematic obţinut a permis evidenţierea rolului hotărâtor, pe care îl are temperatura băii de vopsire spumată asupra eficacităţii procesului. La temperaturi mai mari calitatea spumei se reduce. S-a observat că rolul concentraţiei agentului de spumare este redus. ro
dc.description.abstract Cette étude examine la possibilité d’obtenir la qualité supérieure dans teignant avec mousse de laine à une température au-dessous de 80oC en établissant un modèle mathématique du procédé. Dans les expériences de la laine dégraissée a été utilisée. Le colorant, qui a été utilisée, était Acide Rouge 17, C.I. 16180. Le modèle mathématique du procédé nous a permis de souligner la grande importance qui la température de la solution a sur le pouvoir de montage du colorant. Il a été conclu que les meilleurs résultats sont obtenus à une température de 80,7oC. Il a été trouvé que le rôle de la concentration d'agent est de moindre importance. fr
dc.description.abstract В работе анализирована возможность высококачественной покраски шерсти пенообразным способом при низкой температуре путем разработки математической модели процесса. Эксперименты были выполнены с обезжиренной шерстью, используя краситель Acid Red 17, C.I. 16180. Полученная математическая модель позволила выделить определяющую роль температуры пенообразной красильной ванны на эффективность процесса. Оптимальные результаты получаются при температуре 80,7oC. При более высоких температурах качество пены пострадает. Выло установлено малое влияние концентрации пенообразующего агента. ru
