Waste fibers produced from manufacturing processes are a byproduct commonly deposited in storing yards and/or landfills and thus results in many serious environmental problems in Iran. If these waste materials could be advantageously put to practical use in any application, it would reduce the burden on the environment and landfills. This paper compares the performance of the stone matrix aspha...

Microwave dyeing was carried out under a variety of conditions in terms of the power and time of a microwave to investigate the effects of microwaving on the dyeability of acrylic fibers. It was found that the dyeability of acrylic fibers were significantly improved under microwave irradiation caused by the increased adsorption of the dye into fibers due to the local over heating and an amplifi...

o bjectives: heat-polymerized acrylic resin has been the most commonly used denture base material for over 60 years. however, the mechanical strength of acrylic resin is not adequate for long-term clinical performance of dentures. consequently, fracture is a com- mon clinical occurrence, which often occurs in the midline of denture base.this study aimed to evaluate the efficacy of cold cure and...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

Background. Acrylic resins used in restorative dentistry are the most popular denture base material, because they have good optical properties and small solubility in body fluids. However their mechanical properties are limited and therefore acrylic resins require different methods of reinforcement one of which can be application of different kinds of fibers. Objectives. To investigate the effe...

Abstract The good mechanical and chemical stability of textile acrylic fibers waste has promoted its candidacy for fabricating low cost membranes wastewater treatment. In this work, nanofiltration based on the were successfully prepared using phase inversion technique. First, membrane solutions with different concentrations (16, 18, 20, 22%) (AF) in dimethyl formamide (DMF) prepared. Evaluation...

Abstract The current research aimed to use waste treat waste; recycling of acrylic fibers combined with nano-chitosan for as an adsorbent remove Congo red (CR) from wastewater. Acrylic (AF) were mixed (NCh) different ratios and converted into films by using phase inversion method prepare two nanocomposites coded, AF-NCh AF-NCh-Epichlorohydrin. have been characterized using; Fourier transform in...
