摘要
In this paper, the filtering effect on fine particle of warp-knitted mesh fabrics was investigated. Polyester yarn (PET) and polyvinylidene fluoride (PVDF) fiber were used as materials to knit the fabrics with five different structures on KS4 tricot warp-knitted machine. After knitting, the fabrics were treated with tourmaline liquid with five different concentrations of tourmaline. Then, the filtration efficiency of samples was tested by the comprehensive test machine. By comparing the filtration efficiency of samples with different concentrations of tourmaline and different structures, the optimal process parameters were obtained that the concentration of tourmaline liquid was 30% and the structure of fabric was one by two insertion. The experimental data of the comprehensive test also revealed that the application of the PVDF and tourmaline did have effects on the promotion of the filtration performance of the warp-knitted fabrics.
