The fibers used in the production of non-woven fabrics are mainly polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, polyethylene fiber (HDPE), and chlorine fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable application type and durable type. According to the production process:

In recent years, the demand for PVC as an industrial raw material has been increasing, which has led to the continuous increase in PVC consumption, which has also led to a large amount of energy consumption.
