Patent leather is a well-known type having mirror-bright gloss finish and produced from goat, calf, cattle, corrected grain crust leathers by the use of patent finishing technique. Due to emission limitations volatile organic compounds, now water-based applications are used in industry instead solvent-based systems still there has been no information literature reveal effect viscosity on charac...
A new type of slowly growing, nonphotochromogenic mycobacterium was recovered from two patients with disseminated disease. The growth characteristics, acid fastness, acids were consistent with those for Mycobacterium species. The results of biochemical investigations, lipid analyses, and comparative 16S rRNA sequencing showed that these isolates represent a new slowly growing Mycobacterium spec...
The dyeing of wool fibers using saffron petals as a natural dye has been studied for first time in this paper. Saffron petal is one of the by-products of fields which are thrown away after harvesting while they can possibly be used. A series of dyeing formulation prepared with saffron petals and different mordants and the mordant effect on hue, light and wash fastness of dyed fibers were invest...
The goal of this project is to assess the effect natural dye absorption from turmeric powder on cotton fabrics. At commencement, fabrics are mordanted with two different processes, one synthetic mordanting, and another bio mordanting. Both mordanting processes done at 100°C temperature for 60 minutes then dyed 80°C minutes. Application was made mordants. After completing dyeing process, color f...
Abstract This study was carried out to utilize the extract of Terminalia catappa leaves as natural dyes powder on cotton fabric using alum mordant and various solvents. were extracted solvents water, 25% ethanol, 50% 75% 100% ethanol at a ratio 1:10 with pre-mordanting fixation methods. Natural characterized parameters colour direction, intensity, fastness. It found that type solvent affected d...
One of the pre-treatment processes on silk is degumming that has much influences on other processing. There are various degumming methods and each one has its own advantages and disadvantages. In this research protease (Alkalase) and Keliab (remaining ashes of "Oshnow" plant obtained from Qom, Yazd and Kashan) used as environmentally friendly compounds for degumming of silk. Different...
