Abstract
An anti-static flash spinning composite non-woven fabric and a preparation method thereof are provided. The preparation method includes the following steps, S1: taking anti-static functional masterbatch and a first polymer as spunbond raw materials, obtaining spunbonded fibre with the spunbond raw materials by a spunbond process, and forming a spunbonded fibre web by aggregating the spunbonded fibre; S2: taking a second polymer as a raw material, obtaining a flash spinning fiber web sheet by a flash spinning process; forming a flash spinning fiber layer by laying the flash spinning fiber web sheet on the spunbonded fibre web to obtain a composite fiber web; S3: performing a cold pressing treatment and a hot rolling treatment on the composite fiber web sequentially, causing the spunbonded fibre web to form a spunbond layer and causing the flash spinning fiber layer to form a flash spinning layer.
