The r-PET spunbond production line takes recycled waste PET bottles, PET fibers, etc. as the main raw materials. These PET products that were originally discarded are, after being processed by the production line, re-converted into spunbond products with practical value, which greatly reduces the environmental pollution caused by plastic waste and improves the recycling rate of resources. The products produced by this production line have physical properties similar to or even better than those produced from traditional virgin raw materials. The spunbond fibers have high strength and good tensile properties, which can meet the requirements for material strength in numerous industrial and daily applications. Moreover, the final products can maintain stable structure and performance, and are not prone to problems such as deformation and aging. This enables them to be widely applied in fields such as agricultural covering, packaging, home textiles, cable protective layers, etc.
