Fini minnu dilannen don, olu bɛ siri ni jiriw ye minnu bɛ wele ko warp ni weft yarns, wa u ka kuran sɔrɔli jɔlen bɛ tali kɛ kosɛbɛ fibre material ni sigida cogoyaw la:
1. Fiyɛriw cogoya : Fiɲɛw (fibres naturelles), u bɛ ji minɛ kosɛbɛ, u bɛ charge (sara) ta nɔgɔya la, wa u tɛ kuran jɔlen dɔɔni dalajɛ; sintetiki fiyɛw (poliyesitɛri, nilon, a ɲɔgɔnnaw) tɛ ji minɛ ka ɲɛ, u bɛ se ka u kɛlɛ kosɛbɛ, wa u bɛ charge mara nɔgɔya la sɔgɔsɔgɔli kɔfɛ. *Textile Research Journal* (2020) ka kunnafoniw b’a jira ko poliyesitɛri fini ka wulicogo jɔlen bɛ se ka tɛmɛ 2000V kan, k’a sɔrɔ a ka c’a la, cotton fini bɛ 500V duguma.
2. Lamini nɛnɛ : Ni fiɲɛ nɛnɛ bɛ 40% duguma, a ka gɛlɛn ji filimu min bɛ taa ni a ye, o ka kɛ fiɲɛ sanfɛ, o bɛ dɔ fara a nɔ kan kosɛbɛ. Kɔrɔbɔliw y’a jira (ka ɲɛsin ASTM D423 sariya ma) ko ni nɛnɛ sera 60% ma, poliyesitɛri fini ka wulicogo jɔlen bɛ dɔgɔya ni 65% ɲɔgɔn ye.
3. Friction Frequency: Friction teliya (i n’a fɔ ni fini bɛ maga fini na taama senfɛ) bɛ charge transfer teliya. Fini minnu sirilen don kosɛbɛ (i n’a fɔ pɔmutɛri ni kanpaɲi) olu ka teli ka kuran jɔlen sɔrɔ ka tɛmɛ finiw kan minnu sirilen don ka ɲɛ (i n’a fɔ gaze) k’a sababu kɛ u ka jiribolo ka bon.
