Title:
EXTRACTION METHOD AND CUTTING DEVICE FOR PLASTIC PARTICLES IN FABRIC
Document Type and Number:
WIPO Patent Application WO/2023/087230
Kind Code:
A1
Abstract:
The present application provides an extraction method for plastic particles in a fabric, comprising the following steps: embedding the fabric with an embedding liquid, and freezing until the fabric is solidified to obtain a solid to be cut; cutting said solid, and collecting solid slices obtained by cutting; and after the solid slices are melted, centrifuging and drying to obtain the plastic particles. Using the extraction method can obtain the plastic particles having a small size and high purity, and is beneficial to provide a technical basis for deep research of pollution of the plastic particles to the ecological environment and harm of the plastic particles to the biological health. The present application further provides a cutting device for plastic particles.
