Filtration of synthetic fibers

Filtration of synthetic fibers

Most synthetic fibers are produced by extrusion, by a thick and viscous liquid is forced through a spinneret. Characterized continuous semi-solid fibers are produced.

Why Filtration?

● Protects against obstruction of the polymer melt filters, screen packs, spinnerets; reduces the
Cleaning frequency.
● Reduces the cost of replacing damaged filter.
● Reduces production downtime.
● Particulate contaminants lead to broken fibers, thereby creating more frequent breakage.
● breakage per ton.
● Consistent fiber quality (minimum breakage per ton).
● Overall, lower costs = higher selling price.

filtration applications

● Purified terephthalic acid (PTA)
● dimethyl terephthalate (DMT)
● ethylene glycol
● Additives: titanium dioxide sludge
● catalyst: antimony trioxide, germanium dioxide
● DM-fiber filtration
● prepolymer and polymer filtration
