Saffron Petals, a by-product for dyeing of wool fibers
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...
متن کاملProperties of antibacterial polypropylene/nanometal composite fibers.
Melt spinning of polypropylene fibers containing silver and zinc nanoparticles was investigated. The nanometals were generally uniformly dispersed in polypropylene, but aggregation of these materials was observed on fiber surface and in fiber cross-sections. The mechanical properties of the resulted composite fibers with low concentration of nanometal were comparable to those for the control P...
متن کاملEffect of Adding Nanoclay on the Mechanical Behaviour of Fine-grained Soil Reinforced with Polypropylene Fibers
In this study the performance of clay nano-particles on the soil reinforced with Polypropylene fibers (PP-fiber) has been investigated. Also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. Soil mixtures were modified with varying percentages of nanoclay and Fibers. Unconfined compressive strength (UCS), Compac...
متن کاملFormation and antifouling properties of amphiphilic coatings on polypropylene fibers.
We describe the formation of amphiphilic polymeric assemblies via a three-step functionalization process applied to polypropylene (PP) nonwovens and to reference hydrophobic self-assembled n-octadecyltrichlorosilane (ODTS) monolayer surfaces. In the first step, denatured proteins (lysozyme or fibrinogen) are adsorbed onto the hydrophobic PP or the ODTS surfaces, followed by cross-linking with g...
متن کاملEffect of Polypropylene Fibers on Strength and Thermal Resistance of Concrete
In this paper, the effect of Polypropylene Fibers added to concrete on strength and thermal resistance of high strength concrete has been investigated. Therefore, five tests have been carried out to reach this goal which it includes; effect of weight percent of polypropylene fibers on mechanical properties of concrete, effect of fiber’s length on the strength of high strength concrete, effect o...
