How long does it take for the plastic bottle to biodegrade? It depends on who you ask, but the average time it takes to completely biodegrade a plastic bottle is 450 years. It could even take as long as 1,000 years.
Textile manufacturers buy the recycled plastic bottles in the form of polyester yarns. After bleaching or dyeing the yarns, they feed into a circular knitting machine. Once knit together, the end product is polyester fabric made from the original recycled bottles.
To make different textures, the polyester fabric will go through a napper machine. Here, it will pass through mechanized bristles that give the fabric texture by raising its surface. It also shears the raised threads with a yarn to even out the surface. Polyester fabric from plastic bottles will become fabrics like fleece wool, corduroy, velvet, and other similar piled textiles.
