Girazi rakanyungudutswa rinonyungudutswa kubva muchoto roendeswa kunzvimbo yega yega kuburikidza netambo yakakosha, kwarinotonhodzwa uye rinokweverwa nekukurumidza kuita filaments. Mushure mekunge dombo raumbwa kuita filaments, filaments dzinofanira kuiswa munzvimbo yekugadziriswa mushure mekugadzirwa. Rinogona kuiswa mu "kurukwa" chete mushure mekusvika padanho repamusoro kuburikidza ne "conditioning".

Machira egirazi ane fiber anowanikwawo mubazi reindasitiri yemachira, iro rinonzi jira remagetsi regirazi rine fiber, iro rinonyanya kushandiswa mukugadzira mabhodhi edunhu akadhindwa.
