| Abstract: | Using the molecular weight of 70,000 polylactic acid(PLA) as raw materials and with two different solvents,we can obtain two kinds of spinning liquid.PLA nanofibers were spun on the spunlace and melt-blown nonwovens,respectively,by electrospinning method.We tested the resistance and efficiency with TSI8130 apparatus,and compared the filter performances.Datas show that the filtration efficiency of spunlace nonwovens and nanofiber composite materials can be increased from near zero to 45.88% when the thickness of nanomaterials is about 2 mm,and to 26.12% when the thickness of which is 1 mm;filtration efficiency of melt-blown nonwoven fabric in both the two thickness increased by 23.7% and 24.6%,but the corresponding filter resistance increased at the same time. |
