Nanofibers layer deposited on the polypropylene non-woven textile for water filters production with the enhanced properties due to potential implementation of plasma technology to the manufacturing process
Original language description
The aim of this functional sample was to perform a set of plasma treatment tests on Polypropylene Spunbond (PP SB) 30 gsm non-woven textile in order to enhance their properties for future use as water filter parts. A Diffuse Coplanar Surface Barrier Discharge (DCSBD) was used as a plasma source and was tested on the industrial manufacturing line.

Technical parameters
The carrier fabric and nanofibers were processed using planar DCSBD electrodes. Plasma was generated in the form of a surface dielectric barrier discharge in air at atmospheric pressure at a supplied H V of 15-20 kHz frequency and 20 kV peak-to-peak voltage. The tested power of the DCSBD was 400 W. Two DCSBD electrodes were installed on the spinning line before the Nanospider machine (pretreatment) and two after the Nanospider machine (post-treatment).
Economical parameters
Plasma pre-treatment of the carrier substrate leads to improved adhesion of the nanofibers to the carrier fabric. This step could omit the lamination step for some types of products using nanofiber membranes (e.g., drapes). The treatment of the nanofiber layer leads to partial sintering and fixing of the fibers together, which again improves their mechanical abrasion resistance. The nanofibers treatment also leads to their chemical modification, which can improve, for example, their wettability and thus their permeability to liquids. Leaving aside the acquisition costs of the plasma treatment apparatus, operating costs can only be expected to be associated with electricity consumption.
