Design and development of warp- knitted fabric with electrostatic  barrier effect


  • Received:2016-06-06 Revised:2016-11-21 Online:2017-02-15 Published:2017-02-27


The influence of different weft structure and mass fraction of tourmaline fabric on the electrostatic barrier behaviors of warp knitted structure fabric was investigated in this paper. The fabric with electrostatic barrier effect of was prepared from the polyester yarn and polyvinylidene fluoride fiber by the combination of warp plain and lining weft process. Tourmaline solution was utilized during the finishing treatment, so that the fabric have a function of electrostatic adsorption effect. The filtration efficiency of fabric of same lining weft process treated with different concentration of tourmaline was measured, that of fabric of different lining weft process treated  with the same concentration of tourmaline was measured, and by comparison, the best lining weft process and tourmaline solution concentration were determined. The results indicated that the fabric has the best filtration efficiency when the tourmatline solution concentration in the finishing treatment was 30%. Under the same condition, when the filter screen was woven by the combination of one-partition-two-lining process, the fabric had the best filter property.
