摘要
The present invention relates to a nonwoven bag filter media mounted inside a dust collector, and more particularly, to polyphenylene sulfide split prefibers and polyphenylene sulfide short fibers / polyphenylene sulfide scrim / polyphenylene sulfide stages. Forming a polyphenylene sulfide quadruple laminate of fibers, needle punching both surfaces of the polyphenylene sulfide quadruple laminate to form a polyphenylene sulfide nonwoven laminate, and laminating the polyphenylene sulfide nonwoven fabric Dividing the polyphenylene sulfide split fibers by applying a waterjet to the short-fiber nonwoven layer before splitting the sieve to form a polyphenylene sulfide nonwoven felt converted to polyphenylene sulfide microfibers, and the polyphenyl It is manufactured by heat-pressing renulfide nonwoven felt and has mechanical strength, heat resistance and chemical resistance The present invention provides a split type polyphenylene sulfide fiber nonwoven bag filter media having excellent, capable of collecting fine dust, easily dusting, and having a low pressure loss of gas when dust is collected.
