Recycled Polyester Staple Fiber (RPSF) is a synthetic fiber made from used PET bottles. These fibers are also used for making geotextile and spinning yarn. Since PET bottles are basically non-biodegradable, it was very challenging to settle them. Therefore, a new technology has developed which helps in the consumption of PET bottles for the production of artificial fiber such as recycled polyester staple fiber. This polyester finds wide spread application in spinning to make spun yarn which is later knitted or woven in fabric.

Re-using of PET / Polyester wastes and utilized PET bottles is perfect job for keeping up cleanliness of the environment. Since there is increasing in textile industry, increasing demand for non-woven fabric and increasing awareness of consumers about recycled PSF and durable textiles is the primary factor in the development of recycled polyester staple fiber market.
The major uses of recycled PET are polyester fiber, strapping and non-food containers. Most thermoplastic can be recycled. PET bottle recycling is more applicable than many other plastic applications because the exclusive use of PET is widely used for carbonated soft drinks and water bottles. The recycling of thermoplastic can pass through two processes. In the past, recycling involves initial raw material where the composition of the polymer is completely destroyed, and the other process involves recycling where the original polymer properties are being maintained.
Recycling of thermoplastic is a permanent initiative. Large amounts of plastic waste are diminishing the environment day by day, so there is an excessive use of initiative for cleaning and sorting of wastes. In Thermoplastic Recycling Industry, the recycling of bottles is the major part which is used in all types of liquid packaging such as water, juice, sauce, detergent, domestic chemicals and carbonated soft drinks. Separation of bottles is very easy due to stability and size. Bottles are separated from waste streams by automated or manual sorting processes.
Recycled Polyester Staple Fiber (RPSF) recycling is a major segment in PET and it has been estimated that RPSF is going to become a future fiber in the entire Textile Industry. This is produced by melting the Thermoplastic PET bottles again and again so that thick material can be obtained in the form of filaments. Filaments can be used as an endless thread and length-defined fiber cut for spinning. After knitting, the fabric is turned into the fabric, such as pullover, jacket or sweatshirt.
