经编结构静电阻隔织物的设计与开发

为探究不同衬纬结构与不同托玛琳质量分数对经编结构静电阻隔织物的影响，采用涤纶纱线和聚偏氟乙烯纤维为原料，通过经编平纹和衬纬工艺相结合的织造方式形成静电阻隔织物样布，并使用托玛琳溶液对织物进行后整理处理，使其具有静电吸附功效。测试相同衬纬工艺下不同质量分数托玛琳溶液处理后样布的过滤效率，以及相同质量分数托玛琳溶液处理不同衬纬工艺样布的过滤效率，经比较得出最佳的衬纬工艺与托玛琳溶液质量分数。测试结果表明：使用质量分数为３０％的托玛琳溶液处理样布，样布的过滤效率最高；在相同质量分数托玛琳溶液处理下，过滤网采用１ 隔２ 衬的工艺组合进行织造时，样布的过滤性能最佳。

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

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 electrostaticbarrier effect of was prepared from thepolyester 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 thefabric have a function of electrostatic adsorption effect. The filtration efficiency of fabric of same lining weftprocess treatedwith different concentration of tourmaline was measured, that of fabric ofdifferent lining weft processtreatedwith the same concentration of tourmaline was measured,and by comparison, the best lining weft process and tourmaline solutionconcentration were determined. The results indicated that the fabric has the bestfiltration efficiency when the tourmatline solution concentration in the finishing treatment was 30%.Underthe same condition, when the filter screen was woven by the combination of one-partition-two-lining process, the fabrichadthe best filter property.
