Conversion of Textile Waste Yarns to Candle Product by Designing Simple Candle Producing Machine

Abstract

During the production of yarn in textile industry, there is high waste generation due to different reasons. These wastes are used for the production of candle and tapper product. In order to be competitive with companies performing similar operation, it requires changing this waste into some product. Since there is no other sector, which produces candle from waste yarn in Ethiopia, and candles are currently imported, which increases the product cost, reduces the availability of the product and results in high transportation cost of the product. Therefore, in order to produce this product at low cost, it is essential to design and manufacture candle-producing machine. The machine has four molds; this means the machine can produce four candles at a time. As we observe from testing of the machine, the candles were produced in 20 minutes. The product of this machine has the height of 20 centimeters and diameter of 0.18 centimeter, which has equivalent parameter with the existing product and is produced by using recycled paraffin wax and waste cotton yarns. During testing of the product, we observe that the product has equivalent performance capacity as the currently available products in the market. The total manufacturing cost of the machine is 3,530 birr; this cost includes machine assembling and welding costs. This machine has its own motion transmission for withdrawal of the product. The machine production efficiency is tested whether it can produce the product or not; for this test, the machine can produce efficiently.
