Abstract
As the strategy of waste-management, it is very important to ensure that waste materials are recycled and reused in different industry in order to protect the ecological environment and there are so many initiatives related to this subject. Especially in the textile industry, recycling of PET bottle waste into recycled polyester fiber (r-PET) has made a difference in the industry to reduce load on environment pollution. In addition, it contributes to reducing the fossil fuels sources, water and energy which is the required amount in the production of synthetic polymers. With supporting these attempts, we have to fulfill our social responsibility in order to preserve the ecological balance. This study aims to compare the tenacity and elongation properties of ring spun yarns produced from r-PET fibers recycled from waste PET bottles and cotton fiber at different blend ratios. Besides, virgin PET fibers were also used to conduct the difference between recycled and virgin fibers. Both r-PET and virgin PET fibers were blended with cotton as 100%, 70%/30%, 50%/50% and 30%/70% ratios. All production parameters were constant to determine the effect of raw materials on yarn tenacity and elongation. Results showed that ring spun yarns containing r-PET fibers had lower tenacity and elongation than virgin PET. On the other hand, the quality parameters of r-PET fibers can be improved by technological developments, and so they will be preferred to preserve the ecological balance.
Highlights
Nowadays, climate change has serious problem for all over the world
It is obvious that yarns containing virgin Polyethylene terephthalate (PET) fiber have higher tenacity than that of recycled polyester fiber (r-PET) fiber
The increase in the synthetic blend ratio leads to higher tenacity of yarns both containing virgin PET and r-PET fibers
Summary
Climate change has serious problem for all over the world. To overcome this problem some attempts have been performed by governments to minimize waste generation or reuse wastes. Polyethylene terephthalate (PET) bottles are produced from raw petrochemical products and waste after use has not affect environment directly. The increasing volume of PET bottle waste causes economical and environmental problems unless to be recycled [1]. It is becoming critical problems, besides environmental and economic awareness, legislations has started to minimize the solid residues [2]. Recycling of PET bottles leads to decrease waste problem and use of raw petrochemical products, water and energy. On the other hand, recycling of PET bottles and using in textile industry give textile products an added value [5,6]. Recycling processes which can be mechanical or chemical are the best
