Melt-blown Nonwoven Fabric is the key material for masks. Due to the outbreak of Covid-19 epidemic, there is vast demand for melt-blown nonwoven fabric while the output is limited due to: limited production machine, restricted production time due to machine breakdown, etc.

Black spots and residues in the screw, barrel and mold is one of the most popular problems, which require frequent mold switch, filter replacement and change of spinneret. Starting from a new machine, the continuous production time can be up to 15 days or even more. As time goes on, black spots, residues and precipitates start to build up in the screw, barrel and mold, which lead to shorter and shorter production cycle. The replacement of filters and spinneret is a very labor demanding and time-consuming task, it lead to low production and high waste at the same time.   

SANP Tech. has conducted in-depth study prior to the Covid-19 epidemic, we provide high efficiency Purging Compound and know how to solve the problem, refer to below video and pictures from manufacturing sites.
